Pump Guide: How to Overcome the Biggest Problems with Pump Life

by vemcoblogs -

Sudden pump failures can disrupt your business and delay project delivery. The hidden cost of breakdowns, owing to business loss, may exceed the preventive maintenance costs of the pumps. Pumps often face delivery failure, priming failure, excessive vibrations, reduced capacity, overload, and loss of displaced liquid. In this blog, we talk about factors affecting the pump life and ways to overcome their challenges.

  1. The type of liquid being pumped: Your quest to prolong your pump life starts with determining the liquid pumped in it. Factors like temperature, viscosity, suspended particles, acidity, etc., of the liquid, are crucial in determining the pump’s ability to withstand exposure.
  2. Material of the pump body: After testing the nature of the liquid, which maintains constant contact with the body of your pump, consider the material of your pump body. Can the pump material withstand contact with a specific type of liquid?
  3. Role of the pump: What’s the usage of your pump? Anticipating the usage of your pump can help in choosing the right one. Pumps play a critical role in some industries, and it is, thus, unwise to use an average pump. Similarly, find out if your business operations require a standardized pump operation or additional features that are available only in specially designed pumps.
  4. Always ensure pump inlet: You must never allow your pump to starve, which is the leading cause of pump seizures. To determine the inlet pressure, you must regularly take the Net Positive Suction Head (NPSH) reading and ensure the NPSH available (NPSHA) exceeds the NPSH value of your pump.
  5. Pump location: The immediate location and surroundings of the pump operation are crucial. Pumps operated outside need special care with regard to temperature and environment. You may need to protect the pump using special shelters or protection closets if there are apprehensions.
  6. Flow rate and pressure: The flow rate and pressure of the displaced liquid is an important consideration. It determines the size, length, and material of the inlet and outlet pipes. Their capacity must match the pressure requirements of the pump’s functions.

An understanding of these aspects affects the depreciation of your pumps and prolonging their valuable life.

How To Calculate The Right CFM or Airflow For Air Compressors

by vemcoblogs -

CFM is the short form of Cubic Feet per Minute (cu ft/min) and as is evident, it has a volume and a time dimension to it. CFM is, in fact, a measurement of how fast air flows into or out of space. The higher the CFM, the higher is the pressure exerted by the tightly compressed air on a pneumatic tool.

Analogous to power, CFM reflects the compressor’s ability to perform work over a certain period of time. While there is no doubt that CFM is a very useful metric of your compressor’s performance, there is, however, a need to understand the concept and arrive at accurate calculations.

Let us first try to understand the relationship between CFM and PSI (Pounds per Square Inch). While the two may seem conceptually alike, they have fairly distinct implications. CFM is the rate of flow of compressed air through a given space. It has a time dimension and is, therefore, a more dynamic metric. On the other hand, PSI is more static and is basically a measure of the pressure created by the compressed air per unit area. CFM is the driver behind PSI, which in turn reflects the Force that a compressor can exert and the amount of work it can get done. Both CFM and PSI determine whether an air compressor can meet your workload demands as each piece of equipment has its own airflow requirement.

There are a number of websites and online calculators that offer a simple and quick calculation of CFM. All you need to do is to enter the variables and within a split second, you arrive at your CFM. However, to gain a deep conceptual understanding of CFM, it is always advisable to do some good old math and arrive at the results through a formula. So, here we go:

CFM = Tank Volume in Cubic Feet x Standard Pressure (ATM) during a Cycle x Cranks per Minute

How to calculate Standard Pressure and Cranks per Minute?

Standard pressure must always be converted to PSI. Remember, 1 ATM = 14.7 PSI

Let’s say, your tank volume is 18 Cu. Ft, Standard pressure is 2 PSI and Cranks per Minute is 1.5.

By simple multiplication of the above-given variables, we get:

18 x 2 x 1.5 = 54 CFM

Another very easy method of calculating CFM is the airflow meter. This gives us the pressure coming out of a fitting and can be installed on individual pieces of equipment or complete systems to provide an instant reading.

Overview Of Multistage Centrifugal Pumps: Here’s All That You Need To Know

by vemcoblogs -

Your usual centrifugal pump can restrict the pressure limit due to the design constraint of a single impeller. However, a Multistage Pump has two or more impellers of the same or different types, i.e., low Net Positive Suction Head (NPSH) suction impeller, double suction impeller, or centrifugal first stage and side-channel impellers.

The design of a Multistage Centrifugal pump is similar to the usual centrifugal pump, except for the multistage parts that channel fluid into the impeller’s eye. The impellers face in the same direction, and this generates a strong thrust. However, this creates a thrust balance, which keeps the thrust down at levels manageable by standard-sized thrust bearings. 

The working mechanism of a multistage centrifugal pump amplifies the thrust at previous levels to move forward. The thrust created by one impeller is cascaded by the next one, causing a build-up of thrust through the stages. The required number of impellers varies as per the final pressure required. The impellers are positioned in a sequence from left to right and the liquid is pushed with continuously rising pressure.

The Multistage Centrifugal Pumps find uses in diverse fields due to their pressure. These are great to pump water against gravity and can be used on constructions on the top floors of a skyscraper. They are also used for spraying and high-pressure cleaning in automotive and allied industrial works. Production of oil and fuel delivery to distant locations also requires high pressure, which Multistage Centrifugal Pumps can manage effectively.

A Multistage Pump is expensive and has a more complex design than the high-pressure duty pump. However, the Multistage Pump is a clear winner in efficiency and reliability. The great thing about these pumps is their uniquely flexible capacity. You can also configure it to have an inter-stage bleed off if you require high pressure at different points and in different directions. You may also run it at varying speeds to improve efficiency. Running the pump at a lower speed reduces noise, which is an important environmental consideration.

Multistage Centrifugal Pumps are available in different variants such as horizontal, vertical, submersible, side-channel pump, and vertical turbine pump. Which Multistage Pump you choose depends entirely upon your requirement and working environment.

Smart Ways To Enhance Pump Performance & Reduce Energy Costs

by vemcoblogs -

Your electricity bills are likely to be expensive if your pumps are not efficient, despite low productivity. In this blog, we will touch upon 10 effective ways to enhance your pump performance and reduce energy costs.

Periodic maintenance:

Your pumps have many moving parts, which could lead to unnecessary friction, wear and tear, noise, and overheating. Therefore, it is important to carry out preventive maintenance by regularly checking parts, like bearings, impellers, packing seals, mechanical seals, etc.

Regular monitoring:

Every part that is vulnerable to faults or troubles must be given special attention and replaced in time. Damaged impellers, clogged pumps, and choked suction pipelines are some problem areas that require keen monitoring.

Use of automated controls:

Instead of physical supervision, you can monitor the parameters remotely through your devices. This helps to enhance the pump’s operational efficiency. KBL’s KirloSmart solution allows remote monitoring of your pumps through the KirloSmart mobile app. 

Avoid excessive heating:

Excessive heating may damage heat-sensitive parts and cause overconsumption of energy. Trimming the pump blades reduces energy generation and eliminates excessive heat.

Match pump capacity with operational needs:

Accurately calculate the required flow rate and try to match the pump capacity with it. Efficiency can drop significantly in case of a mismatch.

Install perfectly sized pumps:

Having a pump that is either too small or big can affect efficiency. If a pump is too small, the enormous pressure to process waste can cause overheating or breakdowns. On the other hand, if the pump is too big, it may have to be throttled to prevent it from running at full capacity. 

Optimize flow rate and head:

This is of paramount importance if you want to ensure high performance and efficiency, and reduce energy consumption.

Use VFDs:

A Variable Frequency Drive manages motor speed. Therefore, rather than operating at a steady speed, irrespective of the load, use VFDs to enhance efficiency and reducing consumption.

We hope these will help you cut down your power bills while making pump operation more efficient.

Solar Farms- The Next Big Thing In Solar Space

by vemcoblogs -

Large-scale solar installations are great for Economies of Scale. In fact, Solar Farms that produce less than one megawatt of power cannot justify their cost of development. Solar Farms are mostly set up in the hinterlands as crowded urban and commercial pockets never provide enough space for their development. To put things into perspective, the Solar Energy Industries Association of the US says that as of date, there are around 12000 major solar projects generating over 166 GW of energy in the country. This mushroom growth of huge Solar Farms is expected to replicate across the world, especially in India that is both a tropical country and has a vast hinterland offering ample space for these projects.

As our energy preferences shift away from fossils, Solar Farms will attain greater significance due to the scale of production, lower costs per unit of energy and other significant benefits that we cover below:

A massive engine of clean energy:

Solar Farms unlike small solar installations have the potential to power townships, villages and even cities in the foreseeable future. You can envision a Solar Farm just like your good old hydro-power project or a thermal power plant. With increasing R&D in the sector, you can expect Solar Farms to be more productive, efficient and feasible. 

The dawn of Agrovoltaics:

Agrovoltaics is beginning to percolate the vocabulary of the Solar Sector. Unlike conventional installations like thermal plants or hydro-power plants, establishing a Solar Farm is not permanent or irreversible. This means the land covered under solar panels and other apparatus can always be re-used for agricultural purposes. Imagine the implications it has on the flexibility of the government’s planning and policy-making.

Energy for everyone:

Solar systems have a significant space factor associated closely with them. This means households or commercial facilities with inadequate space will never be able to accommodate a solar system on their rooftops or batteries in a dedicated room. This issue is however resolved by the Solar Farms that become the singular source of energy to power considerably large settlements from a distance.

No noise or other hazards:

Solar Farms go easy on the environment in more ways than one. They not just have zero emissions and can significantly help reduce our Carbon footprint as a society; they are also noise-less. Solar Farms get accommodated very naturally into your surroundings and have barely any effect on the communities, flora and fauna around them. These farms also do not release any hazardous wastes into the environment, quite unlike thermal and nuclear power plants.

The Sun Is Up And Bright. Let’s See How We Still Face Challenges In The Solar Energy Industry

by vemcoblogs -

While Solar Energy is touted to be the fuel for the future, some significant challenges hinder us from making the most of this inexhaustible resource. However, as Solar R&D evolves, our hopes to tackle these challenges effectively will see a steady and upward trajectory. Having said that, the journey starts by identifying these challenges first, and in this blog, we do exactly that.

Dependence on nature:

Natural forces like seasons, geographical location and clouds determine the amount of Solar Energy that you can produce at a given time and place. This is absolutely beyond the control of humans and is likely to remain so, at least in the foreseeable future. Techniques to reduce the effect of these natural forces will have to be worked out so that users may bypass these challenges.

Quality of power:

This refers to the availability and voltage that solar systems can give us. Inconsistent power and fluctuating voltage are not acceptable, especially in commercial applications. This has serious implications for the reliability of this resource. For sectors that require emergency power such as healthcare, solar could struggle to find takers in the coming years. Only as the reliability-to-cost ratio improves in these areas will solar power will find greater acceptability.

Locational challenges:

Geography is a huge determinant in Solar Energy on more than one level. Globally, solar power fits best in the tropical regions that receive plenty of suns all year round. Latitudes further away from the equator will struggle to accommodate it. On a more local level, solar plants may have to be located in a large and open area, such as a desert or abandoned lands. This affects the availability of the resource to the human settlements, especially in urban areas that are in greater need of solar power.

Investment in Solar:

As a thumb rule, the first-time investment in any new technology is always hefty. This is also true of Solar Energy. There is a pressing need to bring all stakeholders such as government agencies, corporations and investors onto a common platform to develop an understanding and channel productive resources of the society into Solar Energy.

Cost of equipment:

The cost of installation of solar apparatus such as panels, storage batteries and VFDs is considerably high. This is quite a disincentive for taking up solar as your staple energy source, especially for households and small commercial undertakings. However, with the passage of time and with adequate research, innovation and competition pouring into the sector, the costs are expected to decline significantly.

Solar energy has gained tremendous traction lately, especially in the wake of the climate change debate. However, the formidable challenges faced on multiple levels require proper redressal through adequate research and development, innovation and investment.

Compressed Air – The Fourth Utility Of The Modern World

by vemcoblogs -

If water, electricity and gas form the trio of essential utilities of the modern world, compressed air has a strong claim to be the fourth one. Air is one of the most ubiquitous resources of nature. When it comes to utilizing it as a source of energy, however, you have to compress and direct it with precision. Compressed air can drive wide-ranging activities and find use in a number of sectors. In this blog, we take you through the importance of this powerful source of energy across the economy.

Manufacturing:

Compressed air finds utility in a number of activities in the manufacturing sector. It powers the actuators, conveyor belts, sprayers and clamping equipment. It also supports casting processes, offers optimal product finishes and helps clean the final products impeccably. 

Construction:

Another sector that requires some heavy lifting and muscle power is construction. Compressed air is used to power pneumatic tools like buffing equipment, nailing, stapling and riveting guns, grinders, drillers, jackhammers and sanders. Lowering and raising heavy loads or demolishing structures also make use of compressed air. Tunnel-digging is another area where compressed air does wonder. They are used for road digging, cutting and cleaning. They also keep the tarmac, debris and other hard surfaces debris-free. 

Agriculture:

Pruning, harvesting, crop fertilising, seed sprinkling and spraying are some of the activities that compressed air helps with, in the agricultural sector. Air compressors power the tractors, sprayers, conveyors and pneumatic fruit pickers. They also facilitate the operation of hydraulic pumps.

Healthcare:

Compressed air is used for administering anaesthesia, power ventilators and other surgical machines in operation theatres. Compressed air is always free of contaminants, pollutants and other particulate matter, making it extremely useful to maintain an allergy and infection-free healthcare facility. Compressed air is also used to inflate emergency mattresses for patients.

Automotive:

In this sector, air compressors find great use in engine construction, assembling car bodies and giving finishing touches to the cars. Intricate components are put in place using compressed air-based pneumatic tools. Plasma cutting, welding and inflating tyres also use compressed air. Finally, the air compressors are used to clean the car and paint it using dry and oil-free compressed air to prevent bubbles or splattering to form on the surface.

The above-given list is not exhaustive and air compressors are used in multiple other areas of the economy. In the future, as the efficiency, precision and power of the pneumatic instruments is improved, air compressors are expected to find the greater application and have an increasingly enlarged role to play.
