Selecting the Right Air Compressor for Tire Inflation: Balancing Power and Portability

Air compressors are multi-purpose equipment and are put to a wide range of uses at home, businesses and factories. For instance, given the power they generate, they can be used for inflating your car tires to maintain an optimum air pressure. However, it is important to know which air compressor is right for which type of tire. VEMC is the top compressor dealer in Mumbai, and in this blog, we tell you how to select the right air compressor for inflating your car tires.

Factors to consider when choosing a tire inflator

  1. Flow rate: This refers to the volume of air that will be compressed and pushed into a tire during a certain span of time. If your vehicle has large tires, it is advisable to use an air compressor with a higher flow rate. Pick-up trucks and SUVs typically require inflators with higher flow rates.
  2. Maximum pressure: Bigger tires can take too long to inflate if your air compressor isn’t generating enough air pressure. Look for a compressor that can offer a pressure of 100-150 PSI to fill your tires fast. This is especially helpful if you’re running a car workshop or a tire factory. 
  3. Portability: Air compressors that operate wirelessly are more handy and portable as compared to the wired ones. These run on rechargeable batteries and do not require any external power supply. These are the best choice and provide a lot of freedom to users if they need to move around too much to inflate a number of vehicles.
  4. Power source: Inflators can either be electric or battery-operated. The latter are more flexible to use as they can be moved around without hassles. However, for longer operations at one location, some users may prefer an electric tire inflator.

Selecting the right balance between power and portability

When it comes to selecting the right air compressor, power and portability appear to be the most visible trade-off. For instance, what typically determines the output of an air compressor is its tank. Bigger the tank, more air it can store and greater will be its productivity. However, it will lower the portability of the air compressor as it may make it bigger and heavier. 

In case you wish to move or travel around with your air compressor, portability becomes an important feature to consider. However, if most of your operations are stationary, it would be much better to look for higher capacity and power.

Safety precautions for tire inflation

Tire inflation can be a slightly dicey task if the right precautions aren’t taken:

  1. It must only be performed by trained personnel.
  2. Read and follow all the product warnings and procedures on your inflator.
  3. Always use inflation cages/restraining devices.
  4. Always center the wheel in an upright position inside an inflation cage.
  5. Wear adequate protective gear while inflating the tires.
  6. Never stand in the trajectory zone.

Understanding Pump Curves

Before investing in a centrifugal pump, it is essential that you understand your requirements and make sure the pump is able to meet them effectively. This is where pump curves come in. Typically, pump curves include performance curves, horsepower and the NPSH needed. VEMC is one of the leading industrial water pumps dealers in Mumbai and in this blog, we tell you all you need to know to understand pump curves.

Definition and basic information displayed on a pump curve

To put it quite simply, a pump curve is a graph that displays the flow rate, head (pressure), efficiency and operating range of a centrifugal pump. Typically, the data is plotted between the flow rate (X-axis) and the head (Y-axis). With an increase in the flow rate, the head decreases gradually. 

Using a pump curve to select the right pump

A pump head signifies the difference between a pump’s inlet and outlet pressure and depends upon pipe designs and configuration. With the increase in the pressure of a centrifugal pump, there is a decrease in the discharge flow with the output dropping to zero. When there is no head to work against, maximum possible output can be achieved within the constraints of the pump design, rotation and impeller speed. The pump curve specifies the range of performance of a pump between these two points.

Performance of a pump can be modified by using a different impeller or operating the pump at varying rotational speeds. A ‘tombstone’ chart is usually used to display the possible range of performance of a particular pump. The upper line of each segment is the pump curve at a particular speed, impeller size and design.

Reading and interpreting pump curve data

Being able to read an interpret pump curve data is necessary to predict the performance of your pump in different operating conditions. Here’s how you can read a pump curve:

  1. Start by identifying the main components of the curve like flow rate and head.
  2. Get acquainted with the performance curve that represents your pump’s head at various flow rates.
  3. Find the duty point, that is, where the system curve intersects with the pump performance curve.
  4. Understand the power curve that represents the electricity consumption of the pump.
  5. Find out the ‘efficiency islands’, that is, zones of maximum efficiency of the pumps.

Limitations of pump curves

While pump curves are theoretically great to predict your pump performance and also select the right pump for your tasks, in real-world situations, things can be slightly different. Factors like low flow operation, bearing failures, cavitation, seal breakage etc. can significantly affect and alter your pump’s performance.

Despite these limitations, a pump curve is an extremely useful tool if you are in the pumping industry. For more on pump performance curves, feel free to get in touch with VEMC by calling on 022 43436655 or email us at marketing@vemc.co.in.

Air Compressor Noise Reduction: Strategies for Quieter Operation in Residential and Industrial Settings

While air compressors are a great source of power across industries and business facilities, these could often disturb the tranquility of a residential house. In these settings, it is necessary that the right strategies for noise-free operation are put in place. VEMC is the leading ELGi compressor dealer in Mumbai and in this blog, we tell you all about reducing the noise produced by your air compressor.

Understanding the sources of noise in air compressors

Before we take action against the noise, it is necessary to understand where it is coming from. The most common sources of noise in an air compressor are:

  1. Intake: The intake of air by a compressor can produce noise due to shifts in pressure or turbulent torrents entering your air compressor.
  2. Discharge: Just as air entering your compressor forcefully produces noise, the compressed air pushed out through the discharge valve can also produce a significant amount of noise.
  3. Motor: Over a period of time, due to friction, wear and tear, or lack of lubrication, the motor of your air compressor can also start making noise.
  4. Vibration: An air compressor is a system of moving parts which can rub against each other during operations, creating a lot of vibration and noise. It may also be caused by simpler reasons like unsteady floor where the compressor rests.

Strategies for reducing air compressor noise

  1. Enclosures: If your compressor is producing noise beyond your tolerance levels, you can simply cut it off from the rest of your home or factory floor by building a physical enclosure around it. Soundproofing the walls of the enclosure can also go a long way in absorbing the noise.
  2. Silencers: Air compressor silencers or mufflers are effective devices available in the market which greatly help reduce the noise produced by an air compressor.
  3. Sound-absorbing material: Unlike steel or concrete, sound-absorbing material absorb rather than reflect the noise produced by a compressor. These include acoustic panels, foam or wood. 
  4. Proper installation location: Installing the compressor in a separate dedicated room can help prevent the noise from affecting the rest of the house or factory. Place the compressor away from walls and corners to prevent the noise from rebounding and amplifying.

Regulations and standards for noise levels

Noise pollution is a massive concern when you’re investing in an air compressor for your home or factory. When buying a compressor in India, you must be aware of the regulations and standards set as per the Noise Pollution (Regulation & Control) Rules, 2000. Here are the noise levels acceptable in various settings as per the rules:

Area codeCategory of Area / ZoneLimits in dB(A) Leq
Day TimeNight Time
(A)Industrial area7570
(B)Commercial area6555
(C)Residential area5545
(D)Silence Zone5040

Advanced Monitoring and Diagnostics for Solar Panel Performance Analysis

Solar energy is gaining steady prominence as one of the most preferred sources of renewable energy across the world. However, to get the maximum out of your investment in solar power systems, it is necessary to keep track of all its critical parameters. Advanced monitoring and diagnostics enable you to do exactly that, for zeroing in on issues and taking timely corrective action. VEMC is a leading solar EPC company based in Mumbai, and in this blog, we tell you all you need to know about performance analysis of your solar power system.

Benefits of advanced monitoring systems

  1. Identify performance issues early: Advanced monitoring and diagnostics technology acts as an early warning system for any performance-related issues which could lead to lower productivity and efficiency.
  2. Optimise system operation: The data collected by advanced mentoring and diagnostics system enables users to zero in on any system issues and take corrective course to optimise system operation.
  3. Maximise energy production: With advanced monitoring systems, users receive a stream of continuous and uninterrupted data which helps keep track of the energy produced by the panels. As soon as deviation is noticed in the production, it could point towards issues such as accumulation of dust, shading of the panels or bird droppings which act as barriers to the sunlight and reduce the energy produced. With timely action, energy production can be maximised. 

Types of data collected by monitoring systems

Monitoring systems keep a track of a wide range of relevant parameters which are critical indicators of your solar power systems’ performance, efficiency and productivity.

  1. Power output: This is one of the most significant parameters that users must track throughout the lifespan of their solar power project. A steady power output at peak levels indicates a healthy solar power system while deviations may signify its decline.
  2. Voltage: This is another important parameter that must be tracked continuously. It also indicates the productivity of your system.
  3. Current: A monitoring system typically has a current sensor that keeps track of the current generated by your solar power system.
  4. Temperature: Solar power systems are known to operate at an optimum temperature. Extremes of temperatures can lead to a reduction in the productivity of your solar power system.
  5. Irradiance: Greater the irradiance received at the surface of the panels, more will be the electricity generation. Suboptimal irradiance may indicate shade due to newly-grown foliage, dust, debris or simply wrong positioning of the panels.

Using data analytics to track performance

Monitoring and diagnostics is all about collecting and analysing data. This is especially useful for identifying performance trends, detecting anomalies and diagnosing potential problems. Analysing data has an important role to play in preventative maintenance, avoiding downtime, and prolonging the lifespan of your solar power system.

What’s a Split Casing pump? Explaining the concepts.

by katlyngrandi2 -

Split Casing pumps are made out of two pieces which are connected together by bolts. They may be split in two ways, vertically and horizontally. If they are horizontally split, it means that they are parallel to the shaft direction; if they are vertically split, it means that they are perpendicular to the shaft direction. It’s important to understand which type of pump you need. These split case pumps are used for water extraction, booster pumping, cooling tower circulation, industrial utility and petrochemical duties. They’re a type of centrifugal pump but they differ from end suction pumps or inline pumps in the sense that the casing and two nozzles are included in a single chamber. The great advantage of these pumps is that they are very efficient for higher flow applications.

Solar Panel Cleaning and Maintenance: Methods and Scheduling

If you own a solar power system, you would realise that it is all about exposing the maximum surface of the panels to the sun for maximum possible time. What can really affect its performance and efficiency is barriers like dust and debris. This makes it extremely important to clean and maintain the panels regularly. We at VEMC are the leading solar panel consultants and installers based in Mumbai, and in this blog we talk about cleaning and maintaining your solar panels.

Factors affecting cleaning frequency

While it is necessary to clean your solar panels regularly, it cannot be feasible in terms of cost and labour to do so too frequently. Here are some decisive factors that determine how frequently you must clean your panels:

  1. Environmental conditions: The larger environmental context you are located in is the foremost factor to determine your cleaning frequency. For instance, you may need to clean the panels more often if you’re located in the middle of a busy urban centre or near a factory, as compared to a bucolic rural setting.
  • Dust accumulation: How much dust accumulates on your panels in a given setting will also determine the cleaning frequency. Dust could be raised by heavy traffic or industrial processes like mining or stone crushing.
  • Bird droppings: Another widely noticed barrier to sunlight shining on your panels is bird droppings. If your facility has a lot of trees nearby, it is quite likely that birds would fly over your panels and pound them with their droppings. This will make regular cleaning necessary.

Safe and effective cleaning methods

Cleaning your solar panels is quite simple and straightforward but for the sake of longevity, you must keep a few guidelines in mind.

  1. Use water and mild detergent: Use de-ionised, rain or tap water to clean your panels. Make sure the water is clean to prevent any mud or contaminants from remaining behind on the panels. Do not use any abrasive, acidic or alkalic cleaners on your panels. A regular mild detergent should do.
  2. Specialised cleaning brushes: These days, a lot of sellers are offering brushes made specifically for solar panels. These are often motorised and can clean in both linear and circular motion. Most importantly, they clean without leaving any marks or scratches on the surface.
  • Robotic cleaners: These are automated systems used to clean solar panel surfaces. These operate by using a combination of mechanical and smart technologies to clean efficiently. These are especially useful when your solar panels are out of reach or located too precariously for manual cleaning.

Recommended cleaning schedules

Solar panels must typically be cleaned twice a year. However, regular inspections are necessary to take more precise decisions and get maximum efficiency. Besides, the above-mentioned factors will also play a key role in scheduling your cleaning.

To get the most out of your solar power systems, cleaning and maintaining them is essential. We at VEMC offer comprehensive solar EPC contracts to our clients which cover everything your solar power system needs post purchase.

Understanding Priming Requirements for Centrifugal Pumps

If you own a centrifugal pump, you must be aware of the process of priming it. Priming simply means filling up the pump casing with the liquid that is to be pumped. This removes any air from the casing and creates a seal between the casing and the impeller. Depending on the type of the pump you’re using, priming can be manual or automatic. VEMC is the leading Kirloskar pump dealer based in Mumbai and in this blog, we tell you all you need to know about priming your centrifugal pump.

Understanding priming

Centrifugal pumps have a priming chamber which is filled with a liquid to expel air and create a vacuum. This helps prevent cavitation of the pump while improving its efficiency. As any Kirloskar pump distributor may tell you, a well-primed pump lasts longer, consumes lesser energy and offers optimum performance.

Different priming methods

  1. Gravity-fed priming: In this type of priming, the casing is filled using the force of gravity, that is, it simply flows downward into the priming chamber without any consumption of external energy.
  2. Vacuum priming: In this type, the vacuum priming system pulls water into the pump allowing it to start. This happens as a result of creation of a vacuum from the top of the impeller down to the level of the water source.
  • Flooding: In this type of priming, the pump is completely flooded with the liquid. However, since these types of pumps cannot handle air, gases or vapours even for a short period of time, there’s always a risk of the liquid being interrupted or bearings getting damaged.

Selecting the appropriate priming method

The right priming method depends upon a number of factors such as:

  1. Pump type: When it comes to priming a pump, there is no one-size-fits-all. Different types of pumps require different priming methods and your Kirloskar pump dealer can provide the right information on this.
  2. Installation: Some pump installation systems may make certain priming methods difficult or impossible. For instance, gravity-fed priming may not be possible for all types of installations.
  3. Operating conditions: Before selecting your priming method, it is important to consider the operating conditions of your pump. These include system designs, constraints, type of liquid to be pumped etc.

Troubleshooting common priming issues

Some of the most common priming issues that customers approach Kirloskar pump distributors with, are:

  1. Air leaks: Air leaks can cause your pump to lose the prime or not prime at all. To fix this, check the pump lid and o-ring for any damage. Even debris or improperly sealed lids or o-rings can cause air leaks.
  2. Insufficient liquid levels: Low water levels can cause a pump to lose the prime. Make sure that the water level is above the minimum level required for operation.
  • Pump not self-priming: This could be caused due to a suction leak. Alternatively, the suction line is too long or its diameter is too wide. To prevent this, use a cling wrap around each joint.

Priming is one of the most crucial aspects of pumping. For more information on priming, feel free to call VEMC at 022 43436655 or email us at marketing@vemc.co.in.

What is a ULFM Approval?

by katlyngrandi2 -

The process of owning or distributing fire pumps is not as simple as for the rest of the pumps. In order for a fire pump to be used, it primarily needs to be tested and then listed strictly for fire services. This is done through a listing and testing agency. Thus, all packages that include fire protection pumps need to meet the ‘National Fire Protection Association’s NFPA 20’ standards in order to be sold. In other words, these fire pumps need to be UL/FM approved so that they can be further used.

UL stands for Underwriters Laboratories whereas FM stands for Factory Mutual and this code ensures that the pumps’ performance has been verified and that they rely upon product safety. We at Vijay Engineering have worked hard to gain certain privileges that not all companies have. Our wish was to provide our customers with fire protection pumps and in order to do that we needed an UL/FM approval. Due to the loyalty that we have established among our clients and cooperators and due to the quality of our products and services, we were qualified to receive the approval.

Why ULFM Approval is a must?

ULFM (Underwriters Laboratories and Factory Mutual) Approval is an essential requirement for various critical reasons:

Safety Assurance: ULFM Approval ensures that fire pumps and related equipment meet rigorous safety standards. These standards are designed to prevent equipment failure, mitigate risks, and ensure that the equipment will perform reliably in high-stress situations, such as during a fire emergency. This safety assurance is vital for protecting lives and property.

Compliance with Regulatory Standards: Fire protection systems must adhere to strict regulations and codes to ensure they are capable of effectively responding to fires. ULFM Approval aligns with the National Fire Protection Association’s NFPA 20 standard, which is a widely recognized and respected set of guidelines for fire pumps. Compliance with these standards is often a legal requirement.

Reliability in Emergency Situations: Fire pumps are mission-critical components of fire protection systems. In the event of a fire, lives and property are at stake. ULFM-approved gate valve is known for its reliability and performance, which is crucial for ensuring that water supply remains consistent and dependable in firefighting situations.

Preventing Catastrophic Failures: Fire pumps need to operate flawlessly when called upon, and a failure in a fire protection system can have catastrophic consequences. ULFM Approval helps identify and prevent potential points of failure through rigorous testing and quality control, reducing the risk of malfunction during a fire emergency.

Insurance Requirements: Many insurance companies require ULFM Approval as a condition for coverage. This requirement is based on the recognition that ULFM-approved equipment is more likely to perform as expected, reducing the likelihood of extensive damage and claims.

Peace of Mind: Knowing that fire pumps and related equipment have undergone extensive testing and quality control processes to earn ULFM Approval provides peace of mind for building owners, operators, and occupants. It instills confidence that the fire protection system will perform as intended when needed most.

Professional Trust: Fire protection professionals, including fire departments and safety inspectors, place trust in ULFM-approved equipment. When an installation includes ULFM-approved components, it signals a commitment to safety and adherence to industry standards.

To sumarise ULFM Approval is a must because it ensures that fire pumps and equipment are safe, reliable, and compliant with essential regulatory standards. This approval is not just a mark of quality; it’s a critical component of any fire protection system that could mean the difference between life and death in a fire emergency.

In conclusion, we offer the UL FM Approved Gate Valves as well as Back Pull Out Pumps. We are proud to say that we were the first, and currently only, valve manufacturers to receive the approval from Factory Mutual. We got the Certificate of Compliance for the fire service water control valves and these include the Non-Rising Stem Gate Valves which are metal seated and the Outside Screw and Yoke.

Understanding Air Compressor Duty Cycle

by vemcoblogs -

Table of Content

Understanding Air Compressor Duty Cycle

If you plan to procure a new air compressor, you will inevitably come across a specification called Duty Cycle in percentage terms. While a 100% duty cycle may be emphatically advertised by a seller and even seem alluring, you will require a more nuanced and in-depth understanding of the concept. VEMC is one of the leading ELGi air compressor dealers in Mumbai and in this blog, we tell you all you need to know about air compressor duty cycles.

Defining a Duty Cycle

The duty cycle of an air compressor simply refers to the time taken to fill its air tank. Every time the tank of an air compressor is full, the pump stops and then starts again. This is known as the run-time versus rest time of a compressor. However, in case a compressor doesn’t have a tank, then its duty cycle will always be 100%.

A compressor with 25% duty cycle means the compressor will have 45 minutes of downtime every hour and be active for only 15 minutes. Likewise, for a compressor with 50% duty cycle will have a downtime for 30 minutes and be active for 30 minutes.

Factors influencing duty cycle selection

  • Air demand: If your air demand is high, you will require an air compressor with longer duty cycle.
  • System size: A larger system will require a longer duty cycle and vice versa.
  • Pressure requirements: Duty cycle also depends upon the pressure required for your task. This means more the pressure required, more should be the duty cycle.

Selecting the right compressor based on duty cycle

Air compressor with intermittent duty cycles

Applications like filling a tyre, powering mechanical tools like wrenches and nailers, or DIY home projects can make use of compressors with intermittent duty cycles.

Air compressor with continuous duty cycles

Applications like powering tools in electronics, furniture and automobile industries, and operating conveyor belt systems use compressors with continuous duty cycles.

A duty cycle can be a critical determining factor when it comes to selecting the right compressor. However, you must be mindful of a few considerations.

  • Avoiding overloading: While it may be quite tempting to select a compressor with highest possible duty cycle, over-cycling can be problematic. Over-cycling could seriously impact the health of your system and reduce its lifespan significantly due to wear and tear. It also reduces the efficiency of the system as quick cycling consumes more energy.
  • Ensuring sufficient capacity for peak demand: When the demand of compressed air is high, you must have adequate capacity to match it. You can use a larger storage tank or try a wide pressure band to ensure this.

Duty cycles are clearly a significant factor to determine the right air compressor type for the right task. For more information on duty cycles or any other air compressor parameter, feel free to call us on 022 43436655 or email us at marketing@vemc.co.in. We are the top ELGi reciprocating compressor and screw compressor dealers based in Mumbai.

Pump Performance Testing of Centrifugal Pumps

Centrifugal pumps are performance tested to verify their design and ensure they match the standards of mechanical integrity. Under controlled conditions, a centrifugal pump is tested to prove its compliance with client and industry standards. VEMC is the leading Kirloskar pump authorised dealer based in Mumbai, and in this blog we tell you all you need to know about pump performance testing.

Key parameters measured during testing

The most important parameters checked during a performance test are:

  1. Flow rate: This simply represents the volume of the liquid that the pump is able to displace.
  2. Head: This is the pressure which the pump is able to generate and will naturally also impact the flow rate.
  3. Power consumption: Both flow rate and head are functions of the power consumption. While doing performance testing of centrifugal pumps, power consumption must be carefully tracked to keep electric bills at minimum levels.
  4. Efficiency: If the pump is operating with limited consumption of electricity, it indicates optimum efficiency levels.

Purpose and benefits of performance testing

  1. Testing mechanical integrity: Performance testing provides insights with respect to the mechanical integrity of the pump. This means that the tested pump has no mechanical problems, say due to high bearing temperatures, vibration levels or leakage of seals and gaskets.
  2. Checking the performance: The pump displays its ability to offer consistent performance. The performance curve is plotted between capacity (X) and head (Y) and enough data must be collected to complete the curve. Vibration is also observed at each data point to ensure it stays in control in real life conditions.
  • NPSH test: This determines the suction performance of a pump. As part of an NPSH test, pressure is reduced until the pump enters the onset of cavitation. Data is collected till the total head begins to decline while capacity is maintained at a constant rate.
  • Efficiency: As energy prices soar, it is necessary to keep energy consumption at a minimum level. This will improve operational efficiency and also to reduce the carbon footprint of the business.

Different test standards and procedures

Certain industry standards are to be followed when testing a centrifugal pump. These are:

  • Hydraulic Institute (HI) “Centrifugal Pump Tests,” American National Standards Institute (ANSI)/HI 1.6-2000
  • American Petroleum Institute (API) Standard 610, 12th edition
  • American Society of Mechanical Engineers (ASME) Power Test Codes (PTC), ASME PTC 8.2-1990
  • HI “Vertical Pump Tests,” ANSI/HI 2.6-1994

Different standards have different testing procedures. For instance, API pumps measure 6 points while undertaking performance testing:

  1. Shut off point
  2. Minimum continuous stable flow
  3. An intermediate flow (flow between the minimum continuous stable flow to BEP/ rated)
  4. Between 95% and 99% of rated
  5. A point between rated and 105% of rated flow, BEP (if rated flow  is not within 5% of BEP),
  6. A point at the end of the allowable operatio

Performance testing can clearly help unearth a range of pump issues such as efficiency deviations, cavitation, excessive vibration etc. To know more about pump performance testing, call us on 022 43436655 or email us at marketing@vemc.co.in. We are the leading Kirloskar dealer in Mumbai.
