How Can Storage Enhance Your Solar Rooftop Project?

Although the benefits of switching to a more sustainable renewable energy like solar are quite well known in India by now, what is less talked about are the virtues of storing solar energy for use in the future. Despite the cost of energy storage sometimes continuing to be a barrier, such as in the case of using Li-Ion batteries for the purpose, there can also be commercial benefits to the practice.

You can meet all your energy needs completely with solar storage

In a state where tariff rates are high, it would make sense for a factory using solar energy to maintain the solar capacity below the contract demand. If 20 to 50 percent of the total energy requirement can be met by consuming energy generated by the rooftop solar installation, the entire 100 percent can be met by combining both this as well as the energy storage to keep it cost-efficient even at peak hours of usage like the afternoons and evenings.

You can increase financial savings significantly

Storing solar energy for later use can reap 20 to 30 percent in financial savings for clients. What’s more, this can be provided in the OPEX financial model too. For those clients that are unable to install more than 1MWp of solar panels through net metering, adding a solar energy storage component with battery storage can make up for it.

Ramp up/down demands for thermal power can become more gradual

Solar capacity firming is a concept where a solar installation is operated along with a thermal power plant. The fluctuations in solar energy output call for abrupt changes in balancing the demand for thermal power. Not only does this put pressure on the thermal power plant and result in inefficiency, it can also incur penalties or a higher tariff. By storing energy, this can be smoothened out and prevented.

A solution for industries using batch production

For industrial applications which require batch processes to be run with an online UPS, solar energy storage provides an alternative solution. Additionally, it can even be stacked up for several different applications even without using solar.

Cleaner and cheaper alternative to diesel generators

Storing solar energy is a far more efficient and sustainable solution than using conventional diesel generators which can cause pollution and drive up carbon footprint.

With rapidly improving technology and gradually reducing costs, solar energy storage can become the predominant solution across industries in the near future.

How a Differential Pressure Gauge Can Help to Maintain the Air Quality in a Compressed Air System

by vemcoblogs -
How a Differential Pressure Gauge Can Help to Maintain the Air Quality in a Compressed Air System

What is differential pressure?

Differential pressure (DP) refers to the difference between two applied points of pressure. When this value tends to fluctuate significantly in a process system, it can be an indication that the component is in need of repair, replacement or maintenance. This is why, it becomes important to understand how to read differential pressure to keep functioning at optimal levels without the equipment breaking down.

What is a differential pressure gauge?

A differential pressure gauge is an instrument that is used to measure the differential pressure in a system and display the results visually. It can monitor the status of the air filter, which is an integral part of most compressed air systems. While the air filter performs a key function in removing contaminants entering the system, it creates a resulting change in pressure between the entry and exit points of the system. With passing time, these points accumulate dirt and get clogged, thus increasing the differential pressure.

A differential pressure gauge can track the changes in differential pressure in the system and alert you when it has reached a point when the filter must be replaced. This is a major benefit in operating an air system, as it can help minimize downtime from a malfunctioning and conduct timely maintenance as and when required.

Here is a look at some important facts about using differential pressure gauges:

  • Although a differential pressure gauge is an indicator of air quality, it does not directly influence the quality of the air that goes out from the system. However, it checks the condition of the air filter in the system and plays a large role in keeping it healthy.
  • If you have a compressed air filter fitted with a differential pressure indicator or monitor, keep in mind that this differs from a true differential pressure guage. Such devices are not as accurate or calibrated as the latter.
  • Be careful not to fall into the trap of thinking that you must only change your compressed air system’s filter when there is an increase in the differential pressure. A marked fluctuation in differential pressure means that the air compressor has to function at higher pressures for prolonged periods of time to overcome the same. So, fluctuations can occur regardless of the condition of the air filter. Besides, any wear and tear in the filter can sometimes prevent the differential pressure from showing a change, despite being clogged up.

A differential pressure gauge is a valuable tool to monitor the condition of the air filter in a compressed air system, which is instrumental in ensuring that the system maintains high standards of air quality.

How Can You Select the Right Dewatering Pump for Your Building?

by vemcoblogs -

Industrial sites often have areas that get clogged with excess water and sludge from things like the rain, a high water table, and melting ice. Dewatering is an essential process in such cases. However, it requires adequate planning and preparation. So how can you select the right dewatering pump for your building? Let’s take a look at factors you should consider.

Pump size

It is the size of the dewatering pump that determines how much load it will be able to process. Pump sizes may range from 1 kW to 10 kW for most industrial purposes. Operating the pump at its maximum capacity makes it prone to mechanical issues which may create downtime. So, if the pump needs to be run continuously, it is better to install multiple dewatering pumps at the site. Called parallel pumping, this method helps your equipment to function for longer periods.

Discharge head

You should also consider the total height of the discharge pipe which is known as the discharge head, along with the height from the point that the water is pumped. If you need to pump the water from a significant height, be sure to choose a higher discharge head. As well, the suction head capacity will determine the depth of the water being pumped.

Flow Rate

The flow rate of the pump indicates how much time the pump will take to complete the work fully. Depending on how fast you would need the dewatering process to be finished, select a pump with a flow rate that matches your requirements appropriately. Keep in mind the size of your site and the amount of water that is to be removed. For a quicker rate, pick a pump that can discharge a higher volume of fluid per minute.

Flexibility of location

If the nature of your work demands that the pumps be moved around easily as opposed to fixed to a particular location, it would be best to choose a pump that is portable. Although it may be tempting to select a cheaper model that is not, doing so would take more time and resources to relocate during operation and cause inconvenience.

Availability of electricity

The dewatering pumps will need electricity to function, so it is important to ensure that there is access to sufficient electricity at the site.

Waste removal

The dewatering process can unearth a lot of sludge and other solids from groundwater. This is why it is necessary to select a pump that can withstand and pass these through an efficient built-in waste removal system.

Keeping the above factors in mind will help you make a prudent choice when looking for the best dewatering pump for your building and application.

How Effectively Do Solar Panels Work On A Cloudy Day?

by vemcoblogs -
Fickle British weather poses threat to future electricity supplies | Financial Times

Solar panels essentially receive sunlight to convert into electricity which can be consumed. This is why they are usually installed in such a way that lets them receive maximum sunshine. However, what happens on days that are particularly cloudy? Do the solar panels still work when there is a significant cloud cover? This is a pertinent question that has a bearing on the functionality of your home or business’s solar power system. To answer it, yes, solar panels do work even when it’s cloudy. Let’s explore this further.

What effect does cloud coverage have on solar output? Factors like the quality of the solar panels and the density of the clouds determine this. Some solar panels work well in reflected light, which implies they can capture a broader spectrum of sunlight and can generate enough power even on overcast days. Usually, solar panels tend to work at 80% of maximum output when it’s cloudy. It takes extremely dense clouds that block the sun’s ray’s completely to prevent solar panels from working.

Let’s also take into account the fact that in big cities where rain and cloud prevail for much of the year, solar panel installations continue to be a rising trend. A major reason for this is the high cost of electricity in such places, and switching to solar panels can reduce electricity bills drastically. It is also an indication that solar panels can run well despite cloudy conditions.

Another factor is a phenomenon that takes place when the sun emerges from a cloud, which causes its light to become magnified due to refraction, thereby resulting in stronger solar radiation even on a cloudy day.

Besides, the main element in producing solar energy is daylight rather than sunlight. Photovoltaic (PV) panels can use either direct or indirect sunlight to capture solar energy to convert into photovoltaic energy, which subsequently gets converted into electricity. On cloudy days, the solar panels may not work at peak efficiency as on sunny days, but you can make up for the difference in solar output with storage solutions like solar net metering. With this, the required electricity can be drawn from the electrical grid even on cloudy days.

All in all, cloud cover is not a matter of concern when it comes to investing in solar energy. This is mainly because on cloudy days there is only a small dip in solar output which lasts a very brief period of time.

Solar Lease or Solar Financing — How Can You Choose What’s Better for You?

by vemcoblogs -

So you’ve decided to make the switch to solar energy. Great move! However, you’re still wondering how best to finance this. Solar lease and solar financing are two of the most common ways with which you can shift to the new system. Both enable you to install solar panels without having to pay the enormous cost of the system upfront. Let’s understand what each of these is.

Solar lease

When you take a solar lease, it means you make a monthly payment to the solar installer rather than owning the solar panels yourself. This reduces the amount of money that you have to pay overall. You benefit from this arrangement by consuming solar energy for your household or business needs and subsequently, reducing your electricity bills because solar energy is efficient and less of it is required to power your home or office than normal electricity.

Solar financing

In solar financing, you take a loan to buy and install the solar panels. You can pay this off over the tenure. With the cost of solar panels steadily declining with time, many are opting for this option as the main benefit is that you gain ownership of the solar panels whereas, in solar leasing, you don’t.

Solar leases vs solar financing

Both solar loans and solar leases allow you to pay a lesser amount of money upfront when installing the solar panels. However, you will need to consider the terms of both scenarios in order to determine which is better for you. Some perks, such as tax exemptions by the government, may not be available to you if you choose the solar leasing option. On the other hand, if the interest rates for solar financing are too high, it may not be ideal for you. However, in the long run, solar financing may be a less costly option rather than paying a continual sum every month like in the case of solar leasing. As well, keep in mind that maintenance becomes less of a responsibility for you when you choose to lease. No matter which option you choose, your utility bills will dip from switching to solar energy, so that is a cost-saving benefit either way.

On the flip side, the return on investment from solar panels is higher when you go for solar financing rather than leasing. When making your final decision, you must weigh the pros and cons of each option and choose the one that matches your needs best. If you value ownership, you may want to consider solar financing. If you prefer to pay a lower sum every month for the entire duration of having the solar panels installed and like the convenience of maintenance and servicing taken care of, you may want to select solar leasing.

How Does a Dewatering Centrifugal Pump Work?

by vemcoblogs -

A dewatering centrifugal pump works much like a regular centrifugal pump, but with one distinctive difference. This type of pump is built with a special feature that allows the fluid passing through it to be controlled and maintained in its movement. Let’s explore what this means and how a dewatering centrifugal pump does this.

What is a dewatering pump used for?

A dewatering centrifugal pump, just as the name suggests, is primarily used to remove water from a particular place and transfer it to another location. A dewatering pump finds several uses across industries including construction, mining, mills, and municipal operations. Any place that needs to be kept dry and clean, such as roads and worksites, will benefit from having a dewatering pump to work with. During the monsoon season especially, a dewatering pump comes in extremely handy thanks to its effective flood control, inland wastewater management, and prompt drainage functions.

How does a dewatering pump work?

A dewatering centrifugal pump actually functions as any other pump does. Just like a centrifugal pump, the dewatering pump makes use of an impeller that has a blade to start and keep up the movement of the water. The fluid goes into a smaller part of the impeller called the impeller eye. The flow of the water is then collected from here and directed to the diffuser, which is a discharge nozzle that is shaped like a cone. This is when the velocity of the water is decreased and the energy of the water flow is changed to pressure energy.

After the above process, the water is then removed from the pump at an angle of 7 to 10 degrees for optimal efficiency. This is the stage of dewatering. To help this process along, usually, an electric motor is used. However, some pumps may use different types of motors.

Special features of a dewatering pump include a robust and compact design, light weight for portability, high fluid capacity, and high abrasion resistance to enable the most efficient handling of muddy water and slurry.

Dewatering centrifugal pumps are also easy to operate and because they are usually installed above the source of water and a ground level site, they are also quite easy to access.

Today, there are dewatering centrifugal pumps available in the market that offer extremely high performance, durability and are very reliable. Many top brands are also providing quality maintenance services. Make sure to select one that offers hassle-free servicing of parts. This will minimize the possibility of downtime and ensure that your dewatering centrifugal pump continues to function at peak efficiency levels.

What You Need to Know About Solar Panels & Other Components Before Installing A Solar Power System

by vemcoblogs -

So you’ve decided to make the shift to using a greener, more renewable source of energy for your business or household. Firstly, congratulations! Secondly, you would want to know how to go about installing a solar power system in your home or facility. We’ve got you covered. Here are some of the main components of the system that you need to know the uses of in order to understand how to proceed with the installation process.

Solar Power System

A solar power plant or system is made up of various components that collectively work to convert sunlight into electricity and transfer it into a form that can be used to power your home or facility. It serves to provide a smarter, sustainable solution to minimize electricity consumption and environmental pollution.

Solar Photovoltaic (PV) Panel

The solar panel forms the backbone of the system. Also known as the solar or photovoltaic (PV) cell, the solar panel performs the crucial function of converting thermal energy from the sun into electricity. There are also certain types of solar panels like monocrystalline and polycrystalline. You need to choose a solar panel based on its efficiency, space requirements, warrant, and cost. The output from the panel is ultimately what matters most.

Battery Charge Controller

The battery charge controller manages the voltage and flow of current from the panels to the battery. It tracks the voltage in the battery and regulates the current accordingly. If the battery is charged completely, it will reduce the current. The controller maintains charge so that the battery is ready to be used.

Net Metering

With net metering, any electricity that you don’t use gets converted back into the grid for later use. It can also be sold back to the utility company and only your net usage of the electricity gets billed.

On-Grid System

An on-grid or grid-tied solar system facilitates the transfer of the surplus or deficiency in the converted electricity back to the grid through net metering. With a net metering, this lets you save on your electricity bills.

Solar Inverter

A solar or photovoltaic inverter converts the electricity that is direct current (DC) from the photovoltaic solar panel into alternating current (AC) which an electrical grid can consume. The solar inverter is one of the most important components of a solar power system.

Installing the solar power system, including the panels and inverter, is a highly specialized task that is best conducted professionally. You can consult an expert in solar power installation among the top solar companies in Mumbai to ensure a smooth installation.

5 benefits of regularly changing compressed air filter elements

by vemcoblogs -
5 benefits of regularly changing compressed air filter elements

Compressed air is indispensable to a vast number of manufacturing and industrial applications including pneumatic tools, petrochemicals, and food processing, among others. Most compressor systems are fitted with a filtration system to optimize the movement of the air and minimize the risk of contamination. To keep the system functioning smoothly, it is necessary to conduct regular maintenance and replace the components that have become worn out. Parts of the air filtration system in the compressor have a limited shelf life and in order to keep working effectively, they must be checked and replaced periodically. Let’s take a look at five benefits that changing the compressor’s air filter elements regularly provides:

1. Maintain a high quality of compressed air

Changing the air filters regularly makes for a safer, cleaner work environment without the risk of undesirable contaminants that can cause damage to your staff and equipment. To keep the air filtration system unclogged and functioning at peak efficiency, you need to change the air filters as often as required. Check with the manufacturer to know what the recommended frequency of your filters is.

2. Protect adsorption dryer beds

In some systems, using fresh new filters enables the adsorption dryer beds to operate at their most efficient levels. With reduced particulate matter present in the airflow over these, they are going to remain healthy more easily and offer maximum advantage.

3. Decrease operational costs

Changing the air filter parts regularly cuts down on the risk of running into problems with the entire system which can result in downtime, costly repairs, and all-around inefficiency. Without proper maintenance of the air filtration system, the compressor has to work harder to deliver the required airflow. This puts a burden on the compressor and makes it consume more energy and be susceptible to damage and lowered durability.

4. More productivity and profitability

An outcome of conducting consistent maintenance and changing the air filters is that you will benefit from a boost in efficiency, thereby resulting in increased productivity as well as profitability for your business.

5. Sense of assurance

Changing the air filtration parts of your compressor system keeps everything operating much more smoothly than if you did not. It is a habit that gives you peace of mind and a sense of assurance that your system is running at the best of its ability in the safest way possible. It reduces the anxiety and inconvenience of unexpected downtime. This in itself is invaluable when it comes to the daily operation of your business or factory.

These benefits far outweigh the consequences of not changing the air filter parts regularly as required. So, keep them in mind when maintaining your air compressor system!

Understanding The Cost of Compressed Air

by vemcoblogs -

Compressed air is an indispensable part of most industries. Without it, entire sectors of production would be defunct! It is so essential that it is referred to as the ‘fourth utility,’ after electricity, water, and gas. However, there is a significant cost attached to it. In fact, about 10% of the electricity consumed industrially goes to generating and using compressed air.

Keeping industrial units supplied with compressed air costs a substantial amount of money. So, it would be prudent for businesses to focus on the consumption of energy, which makes up the majority of the cost of generating compressed air. Energy consumption costs are much higher than the initial cost of air compressors or their maintenance. A whopping 80% of the total cost of the compressed air system will be from the electricity it uses up. Because this is such a huge percentage, determining the cost of compressed air becomes important in order to minimize waste heat and electricity bills.

To identify the ways that you can save such costs, take a look at your business’s requirements of compressed air as well as the components of your compressed air system, along with all the associated costs. When you do this, make sure to account not just for your business’s current system, but also for the one you envision to be in place in the future. Plan for the longer-term demands rather than just the current ones.

Here’s an overview of the components in a compressed air system that you need to look at:

Air compressors

Aim to have an energy-efficient air compressor rather than one that just carries a lower price tag. As mentioned earlier, the initial cost is just a small fraction of the total cost.

Dryers and filters

Compressed air has contaminants that, depending on the application at hand, need to be filtered. There is an additional cost and equipment to this process, so be mindful of that.

Drains

Drains remove the collected condensate of the compressed air system as required.

Piping

A good piping system is crucial for smooth movement of the air and eliminates air restrictions, leakages, and pressure drops.

Ventilation

Ventilation is key to cutting down heat circulation to subsequently reduce energy consumption.

Air leakage

It is of paramount importance to detect and fix any air leaks because these can have a heavy cost otherwise. Monitor your air compressor constantly to prevent this from occurring.

Central controller

In systems that consist of more than one air compressor, a central controller may play a big part. It can decrease the average pressure band (a pressure reduction by one bar reduces energy usage by 7%), regulate the compressor speed, and control compressor capacity.

A streamlined air compressor system strategy can help you reduce your operational costs significantly, so plan ahead and reap the benefits!

Solar Success Story: Installing a Rooftop Solar PV System for Abhijeet Dies & Tools

by vemcoblogs -

VEMC recently completed the installation of a 182.49kWp solar rooftop system at Abhijeet Dies & Tools Pvt Ltd. in Naigaon East, Bapane, Maharashtra. We designed this solar rooftop photovoltaic (SRTPV) system using the space available on the terrace at the client’s site with a module by Jinko and inverters by Polycab.

Execution

The application of the installation was in machinery and light loads. The project commenced in November 2021 and was completed in January 2022, well within the targeted time, but for a slight delay in net meter installation due to a hold up by Maharashtra State Electricity Distribution Company Limited.

Superior safety protocols

We executed the installation smoothly and took extra precautions to maintain the highest levels of operational safety. We ensured that every team member working on the site used the required personal protective equipment (PPE) including safety helmet, safety harness, and safety belt. We were also careful not to use mobile phones and other electric devices that could distract us during the process. Additionally, we used the crane or forklift to unload the modules and checked that a qualified person operated it. We kept the speed limit below 10km per hour.

Training and instructions

We designated an adequately sized team to lift the modules manually up the stairs so that they were easy to handle. We also gave our team rigorous training and proper instruction during the installation which they followed diligently. This way, we were able to avoid damage to any of the modules. The entire process was supervised by a team of qualified engineers.

Routing the AC cable

When the AC cable was routed, the tray was secured from any wear and tear. Once the tray was clear of any damage, it was carefully positioned to keep it moisture free.

Earthing

During the process of earthing, the speed of the boring machine was always maintained at below 10 km per hour. Our team strictly adhered to materials like cotton, PVC, and leather gloves while fixing electrodes, handling the backfilling compound, and connecting the electrical panel. Welding goggles, face shields, and aprons was also used during the welding of the system.

How we overcame challenges

Effective time management, cost management, quality control, team management, procurement management and communication skills were the key ingredients in the successful execution and completion of the project.

Learnings

A Guide To Select The Best Water Pump For Industrial Use In India

by vemcoblogs -

We need water for a variety of essential purposes — whether it is to cook, wash, clean, or perform industrial functions. This water comes to us from the source through a pump. When you are buying a water pump, there are a number of factors to consider before identifying the right kind for your application. Before we look at what these different factors are, watch this video to get an idea about how to select a water pump:

https://www.youtube.com/watch?v=9i_c-LBEXkw&ab_channel=VijayEngineeringandMachineryCompany

Flow rate

Given in cubic metres per hour (m3/h) or litres per minute (l/min), the flow rate of the pump measures its efficiency, that is, how much water it can pump out within a certain period of time. For industrial applications, this flow rate should ideally be on the higher side, of at least 2000 litres per minute. Another reason that the flow rate is so important is that it determines the daily energy consumption as well as the durability of the pump. The lower the flow rate, the higher the energy consumed due to more prolonged usage.

Discharge head

The total height of the discharge pipe which is known as the discharge head, as well as the height from where the water is pumped, are further aspects to consider when choosing the water pump. If you need to pump the water from a significant height, make sure that you choose a higher discharge head. Additionally, the suction head capacity will determine the depth of the water being pumped.

Inlet

The size of the inlet facilitates the correct flow of the water. Too small an inlet will create friction and a subsequent loss on the pump system. So, be careful that you choose a good-sized inlet for optimal water flow and pump performance.

Water quality

It is necessary to keep in mind that different water pumps and motors, such as trash pumps and dewatering pumps, are built to work with different kinds of water. Trash pumps transfer dirty water quickly while the latter kind moves clean water between locations. When you choose a water pump for your needs, it must fit the specific purpose you require it for and should not be used inappropriately.

Pump quality

Just as the quality of the water that goes into the pump must be suitable, you must also consider the quality of the pump itself. For the maximum efficiency and compatibility, select a pump from a reputed brand and do not compromise on its quality and design. A good quality pump will last much longer, cost much less to maintain, and will consume less energy in the long run. Kirloskar is a trusted name in the industry and would be a safe bet.

Here’s How You Can Understand Centrifugal Pump And Motor Torque-Speed Curves

by vemcoblogs -

A centrifugal pump is powered by a motor that has to produce adequate torque to start off the pump and take it up to the best speed. Without enough torque, the motor might not be able to start the pump at all or only have it function at a lower speed.

To determine the motor that is most appropriate for a pump, we use what is called the pump’s torque-speed curve. We can make this by vertically mapping the percentage of full load torque (FLT) against the percentage of horizontally mapped full load speed (FLS).

The torque-speed curve is common in all centrifugal pumps because though the pump torque changes with its squared speed, when the full load speed (FLS) is at zero percent or at rest, the full load torque (FLT) will never simultaneously be at zero percent. The motor must overcome static friction and inertia in order to start a rotating pump. This brings us to the question of how much full load torque is needed to do this. The answer — about 20% of full load torque. As the speed of the pump increases, the torque that is needed slowly decreases. (At 15% full load speed, about 5 to 10% full load torque is needed.)

Horsepower (HP) is a combination of speed denoted by RPM, and torque. The horsepower of a motor is a basic measure of its abilities. The torque of a motor is calculated with the following formula:

T = (5,250 x HP) / N

(T = Torque, and N = RPM)

When you need to select a new motor for your pump, there are three important values you need to look at. These are:

  • Torque at zero flow
  • Torque at rated flow
  • Torque at maximum flow

Additionally, you will need to consider the inertia value of the pump at the motor shaft. The higher this is, the more time the motor will take to start off the pump and get it to the full load speed. This is important because the longer this is, the more heat is generated. The size of the motor must be suited to handle the inertia of the pump. Otherwise, the motor’s windings may get damaged.

In the case of the motor driving the pump directly, the inertia values of the pump-motor combination and the pump itself will remain constant no matter the speed of the pump. However, if both a gearbox and motor drive the pump, the inertia values will be affected greatly.

To choose the right kind of motor for your centrifugal pump, the above factors are important to keep in mind.

How Can You Mitigate a Mechanical Shaft Seal Leakage?

by vemcoblogs -
  • How Can You Mitigate a Mechanical Shaft Seal Leakage?

Why does leakage occur in a centrifugal pump? To understand this, we must first understand how a centrifugal pump basically works. As fluid goes through its impeller eye and up the impeller vanes, it starts with low pressure and velocity. As it flows into the volute and gets ready to exit, both the pressure and velocity increase. As the fluid flows out through the discharge, the pressure is high but the velocity gets reduced. The flow then goes out of the pump, which makes the pump exert pressure and raise the energy of the fluid.

When a component of the pump such as static joints and hydraulic malfunction, the whole system might break down. However, a majority of pump failures happen due to the mechanical seal of the pump malfunctioning.

A mechanical seal controls the leakage between a liquid and a rotating shaft. To do this, essentially all seals have to leak in order to maintain a film of fluid over the whole face of the mechanical seal. The leakage from the atmospheric side is quite less. But the leakage between the mechanical seal shafts and sleeves can cause significant issues. Often, the reason these happen is because of the fretting of the O-ring seal on the shaft. You will notice substances dripping from behind the seal close to the drive collar. Polishing the fretted part can provide a temporary fix, but it will not give you a solution. Here are some options you can choose in the short and long term:

Short term solutions

Replacing the shaft could be a practical option given that the maintenance cost is low and you would not have to overhaul the entire pump system.

When repairing or replacing the shaft is proving to be difficult, you can opt for a modified seal but you may have to plan in advance.

You can try relocating the O-ring of the seal sleeve with the help of a local technician. When you get to the bottom of the issue, you can check where the damage on the shaft is and shift the O-ring accordingly. If you still require a new sleeve, the cost will be only a little bit higher.

Long-term solutions

Upgrade the shaft to a higher quality material.

Consult a pump technician and coat the shaft below the seal sleeve with a substance like tungsten carbide. How much of the shaft you may need to coat will depend on the damage. Avoid the area around the drive collar set screws. Make sure to enlist professional support for this.

Solar Panels And EV Stations: How Solar-Powered EV Charging Stations Are Becoming the Prevalent Alternative

by vemcoblogs -
Solar Panels And EV Stations

What is an EV charging station?

Electric vehicles (EVs) powered by renewable energy are steadily emerging as the sustainable alternative to fuel-powered vehicles. With more and more electric vehicles on the road, there also comes the need to be able to charge them.

From where do EV stations source their energy?

EVs are charged in a charging station, which is also referred to as an electric vehicle supply equipment (EVSE) or an EV charger. An EVSE is a device that provides the electrical power to charge all kinds of electric vehicles. Now, although the source of power for EVs may be clean, the same might not be true for that of charging stations! In fact, natural gas is the most common source of power for charging stations. It is very affordable and widely available. However, all electricity is not necessarily generated by only fossil fuels. Charging stations are connected to the ‘grid’ or power supply, so although the EV produces zero emissions, the energy it draws from charging stations usually is not. But, even charging stations have can take the route of using clean, renewable energy.

How are EV stations and solar panels connected?

One of the most sustainable solutions to powering EV charging stations is through solar energy. Solar-powered stations for electric vehicles are one of the best ways to cut down on depending on fossil fuels.

To switch to solar for your charging station, you first need to determine the number of solar panels you would require to set up. For this, first consider how much you drive on average. For example, if you drive 300 km in one month, that would be about 10 km per day. Now, take a look at the energy requirement in kilowatt per hour (kWh) of your electric vehicle. Then, estimate how much direct sunlight you receive in your area. This will give you an idea of how much solar energy you would need, and how many solar panels you would need to set up to generate enough of it.

What is the future of solar-powered EV charging stations?

With the effects of global warming becoming an alarming concern, solar-powered EVs and charging stations are fast being hailed as the better alternative. A recent report found solar rooftop photovoltaic energy from solar panels to be an economic and feasible solution for EV charging, while also offering a cleaner source of energy.

Solar rooftop photovoltaic systems provide a plethora of benefits in EV charging. Thanks to their modular design, they can be installed easily. They are also a cost-efficient solution compared to charging from the grid. They minimize carbon emissions and also soften the blow from surging demands of EV charging power on the grid. A net metering solution can solve the issue of a disparity between solar energy generation and consumption.

Here’s What You Need to Know About ISO Classes for Compressed Air Quality

What You Need to Know About ISO Classes for Compressed Air Quality

We’ve heard the term “ISO standards” quite frequently. But what exactly are they, and why are they so important? Let’s take a look at the concept. The International Standards Organisation (ISO) is a non-governmental body made up of a network of institutes from 159 different countries. ISO is the world’s largest developer and publisher of international standards and is accepted universally.

Compressed air is an indispensable utility that is used widely across different industries. But, compressed air is not all of uniform quality. Some uses, such as pharmaceutical production and food handling, call for impeccable quality and cleanliness of the air. In other cases, the primary objective may be to ensure the lifetime and reliability of industrial tools that are powered by air. The ISO standards play a key role in determining the level of air purity required for your particular application. Meeting ISO standards is also important in maintaining and protecting the quality of your production. In some cases, not complying with them can lead to heavy penalties or even your production facility being shut down!

The ISO 8573 air quality standards and ISO 12500 compressed air filter standards help lay a sound foundation for selecting the right air treatment products. ISO8573 is the compressed air quality standard and comprises nine separate parts — part 1 for quality requirements of the compressed air, and parts 2 to 9 for the methods of testing for a range of contaminants.

Compressed air contains contaminants like moisture and pollutants, and must be filtered according to the application’s requirements. Usually, the purer the air must be, the more costly it is to produce. This is why it is crucial to choose the right levels of air purity in order to reduce costs and benefit the environment.

The ISO 8573-1:2010 is a useful tool that makes the task of choosing the right air purity for your application that much easier. It ranks the acceptable levels of different types of contaminants as classes.

The ISO 8573-1:2010 standard is divided into three groups of contaminants—solid particles, water (including liquid and vapor), and oil. Each of these categories is further classified into ten different purity classes — eight for particulates, ten for water, and five for oil. The lower the assigned number to a category, the higher the air purity requirement for it. For example, class 5 would require far less air purity than class 1.

Now that you know how to match the ISO class to the compressed air quality required, how will you select a filter? The answer is simple — just find the particular ISO class on the filter. Once you identify the ISO class for your particular task, planning the equipment you would need becomes much easier.

VEMC provides a variety of Elgi air compressors. For more help with understanding ISO classes for compressed air quality, contact us on +919819907445 and we would be happy to assist you.

What does it mean if your pump is self-priming?

by vemcoblogs -

In several applications that require liquid to be pumped, the pump must be kept above the level of liquid. This lets air into the line, which can often create issues like overheating and pump failure. To avoid this from happening, a self-priming pump is used to empty out the air before moving the fluids. 

A self-priming pump is like other centrifugal pumps but is built with an outer casing that contains the fluid being pumped. The rotation of the impeller in this casing creates an area with low pressure at the impeller’s eye. This causes the fluid, along with the air, to get pushed up into the pump through the line of suction. Through its motion, the self-priming pump causes the air to separate from the fluid and get released from the casing. When all of the air has escaped, the pump allows the fluid to flow. Thus, a self-priming pump essentially removes any air pockets from the fluid to ensure smooth delivery by the pump. 

The main difference between a self-priming pump and a regular centrifugal pump is that there is no need to physically prime the former type, as its extra in-built mechanism is designed to do just that.

Practical uses

A self-priming pump can be used for anything that requires a standard centrifugal pump. This can include pumping water, sewage waste or other industrial applications. 

It is important to choose the right kind of pump for the task at hand, as well as the correct sized pump that matches the flow and head. Then, a net positive suction head (NPSH) calculation must be conducted to make sure there is adequate atmospheric pressure to sustain the required flow. Lastly, the speed of the pump must be high enough to be able to prime itself. The size of its line of suction too must be selected carefully.

Advantages of a self-priming pump

Because self-priming pumps are installed above the fluid source, the infrastructure needed to set them up is relatively less. They are easy to access due to their ground-level location. Maintenance and repair too, are simpler to conduct on a self-priming pump than on a regular centrifugal pump.

Self-priming pumps can handle a variety of liquids as well as slurries and suspended solids. They are also ideal for frequent pumping operations, as the steps involving pump priming at the start are eliminated. As well, they use less power and time to run than other centrifugal pumps. Self-priming pumps are also safer to operate, as hoists or cranes are not required for their use.

Limitations of a self-priming pump

Self-priming pumps have a limited suction lift. There are limitations in the NPSH and fluid temperature and can cause a loss of friction in the line of suction.
