A gas booster pump helps to increase the pressure of the gas to enhance the flow and efficiency of a given system. Various types of gas booster pumps exist today, and they include the following:
Reciprocating gas booster pumps
This kind of booster pump is mainly operated by a power piston to move a working fluid across the barrier containing the gas. A gas compression is then performed by a gas piston, which is attached to the working fluid piston. It is also worth noting that these types of gas booster pumps feature a small size even though they can operate at high pressures.
Turbine gas booster pumps
A turbine gas booster pump operates by extracting energy from the gas flow to increase the gas pressure through a rotatory motion. An impeller present in the turbine gas booster pump spins and compresses the gas, while the gas usually passes through the blades where its velocity is decreased and increased. These turbine booster pumps are normally suitable for crying processes where a small loss of the gas is tolerable.
Diaphragm booster pumps
Diaphragm booster pumps are gas-operated pumps commonly used to help boost the gas pressure. These special pumps have a diaphragm that oscillates and compresses the gas in a series of gas chambers. The diaphragm is a critical component that is elastic and flexible and can easily change shapes, which allows it to push and pull away from the gas. In this case, the gas will be drawn into the chamber when the diaphragm expands, and it will be pushed out when it contracts.
Rotary gas booster pumps
This type of booster pump features rotor that will compress the gas by reducing the volume between them and gives out an increased pressure. The rotors are usually engineered to mesh with each other but still leave a small space between them. These types of rotary-based gas booster pumps generate a smooth flow because of the continuous operation.
Gas booster pumps are applied in various means, increasing the gas pressure in several industrial systems. These applications include:
Oil and gas industry
Gas booster pumps are crucial in the oil and gas industry for gas reinjection and transportation. A pneumatic booster pump will help in gas reinjection into the reservoir in order to maintain pressure and enhance oil extraction. With a gas booster pump for natural gas, it is also possible to compress and transport natural gas through pipelines.
Hydrogen fuel systems
In hydrogen fuel systems, gas booster pumps are utilized to increase the hydrogen gas pressure for fuel cell vehicles. These hydrogen gas booster pumps also help store hydrogen in the compressed tanks to ensure the availability of the fuel for the vehicle.
Manufacturing processes
Gas booster pumps are widely utilized in the manufacturing processes that require gas, including the semiconductor industry. In this vacuum, gas booster pumps will be applied to maintain the vacuum pressure or increase the gas for the chemical processes such as metal etching or deposition.
Water treatment
In water treatment, especially in reverse osmosis systems, gas booster pumps are used to help increase the water pressure in order to allow proper filtration. They will help ensure the availability of clean water.Gas booster pumps are applicable in different areas and help increase the overall efficiency of the system.
Gas mixture
Gas booster pumps are applied in gas mixture, where the required gas pressure is boosted to create a specific mixture. In this instance, the gas will be fed into a blending machine, where it will be combined for use in several applications, like welding and diving.
Pharmaceutical and chemical processing
Gas booster pumps are applied in chemical processing in providing the desired pressure for gas, which is used in the chemical reaction. They also help in pharmaceutical sectors in the gas chromatography, which is used to analyze the substance constituents.
The gas booster pump should be selected based on the following key factors:
Pressure ratio
Here, the pressure ratio is the key factor in determining the main operating capability of a given gas booster pump. This ratio is defined as the capacity of the pump to increase the inlet pressure to the desired outlet pressure. Since the pressure ratio differs from one pump to another because of designs and intended use, it is, therefore, important to choose a boaster that has the required pressure range for the specific application.
Gas types and characteristics
Other than the pressure ratio, other factors like gas composition, viscosity, and temperature influence the gas booster pump selection. Ensure the materials used to construct the pump are compatible with the gas to avoid any possible chemical reactions that may bring about corrosion or wear. For example, a diaphragm gas booster pump is meant to handle reactive gases such as hydrogen or ammonia because of the diaphragm that acts as a barrier between the gas and the working components. A viscous gas might require a pump with specific design features to help prevent cavitation or stagnation.
Flow rate
This is one of the most important considerations. A flow rate is the amount of gas the pump can possibly boost within a given period of time. Depending on the application, the flow rate will determine the gas booster pump to go for. For example, quasi-static application necessitates lower flow rates, while dynamic application demands higher flow rates.
Efficiency and energy consumption
Gas booster pump efficiency is usually affected by the energy consumption, which is an important factor, especially when it comes to sustained operations. Higher pumping efficiency will, in turn, reduce the energy costs and make the operations more economically viable. Consider the energy source and ensure it aligns with the overall system to avoid conflicts.
Maintenance and durability
Think about the maintenance needs and the life expectancy of the gas booster pump. In this instance, gas booster pumps, which are considered to be more durable and require less frequent maintenance, are frequently recommended for use in critical application areas.
Keep the area around the pump clean
A gas booster pump is efficiently worked without excess dirt, dust, or debris. This means that the area around the gas booster pump should be cleaned so as to minimize any potential contaminants that may enter the system. Besides, regular cleaning reduces the likelihood of any possible hazards occurring, which may be caused by slipping or tripping.
Check for leaks regularly
Leaks are normally dangerous since they can affect the efficiency and even pose safety issues. Alway check for the signs of leaks, such as hissing sounds or visible signs of gas escaping, and rectify the problem as soon as possible. When one usually identifies a leak, it is advisable to turn off the gas supply, then wait for any signs of evacuation before carrying out repair or replacing affected parts.
Monitor pressure and temperature
In this case, monitoring gas booster pump temperature and pressure is essential in ascertaining that the pump is operating within the recommended limits. Excessive pressure or insufficient extreme temperatures can result in damage, thus reducing the pump's efficiency. Use monitoring devices of the gas pressure booster to track any fluctuations or abnormalities.
Inspect hoses and connections
Since hoses play an important role in the gas booster pump process, ensure they have no signs of wear, cracks, or damage. Regularly check the connection to ensure they are tight and secure; this will help prevent leakage. Any damaged or worn-out hoses should be immediately replaced to avoid incidences that may halt work.
Properly lubricate moving parts
Proper lubrication keeps it in the right condition, as this reduces friction and wear. Be sure to use the right type of lube as stated by the manufacturer and lube it in regular intervals. It is also very important that cleanliness be maintained to avoid the accumulation of dirt, which will hinder the lube from performing its function effectively.
Follow a regular maintenance schedule
Following a regular maintenance schedule is important for the long-term functioning of the gas booster pump. This schedule should involve routine checks, lube applications, part replacements, and any other required maintenance. Close adherence to the manufacturer's instructions will ensure that all important maintenance activities are accomplished in time.
