High Pressure Gas Booster, Pneumatic-Driven Gas Booster, Air Driven Liquid Pump

High Pressure Gas Booster Pump, Air Driven Liquid Pump

High Pressure Gas Booster Pumps are divided into gas-liquid booster pumps and gas booster pumps. The principle of the gas-liquid booster pump is to use the low pressure of a large-area piston to generate high hydraulic pressure for a small-area piston.

Booster Pumps Classification

  1. Gas booster pumps such as nitrogen, argon, oxygen, hydrogen, etc.
  2. Liquid booster pumps such as: water, hydraulic oil, etc.
  3. Air booster pump
  4. Refrigerant booster pump

High Pressure Gas Booster Pump Features

  1. High output pressure: liquid pump up to 640MPa, air pump up to 200MPa
  2. Wide range of use: the working medium can be hydraulic oil, water and most chemically corrosive liquids, and has high reliability and long maintenance-free life.
  3. Wide range of output flow: For all types of pumps, only a small driving air pressure is required to work smoothly. At this time, a small flow is obtained, and different flow can be obtained after adjusting the driving air intake.
  4. Flexible application: choose different types of pumps to obtain different pressure areas.
  5. Easy to adjust: within the pressure range of the pump, adjust the regulating valve to adjust the intake pressure, and the output hydraulic pressure can be adjusted steplessly accordingly.
  6. Automatic pressure maintenance: No matter what causes the pressure of the pressure maintenance circuit to drop, it will automatically start to supplement the leakage pressure and keep the circuit pressure constant.
  7. Safe operation: It is driven by gas, without arc and spark, and can be used in dangerous places.

High Pressure Gas Booster Pump Features and Applications

  1. Driven by a variety of gases: compressed air, nitrogen, water vapor, natural gas, etc. can be used as the driving source of the pump.
  2. Wide range of applications: In the industrial field, it is used for clamping machine tool chucks, accumulator inflation, high-pressure bottle inflation, and conversion of reduced-pressure gas to high-pressure gas, etc. Where the pressure of the air source is not high enough, whether it is a machine or a test device, a booster pump can be used.
  3. Automatic pressure maintenance: No matter what causes the pressure of the pressure maintenance circuit to drop, the booster pump will automatically start to supplement the leakage pressure and keep the circuit pressure constant.
  4. Safe operation: It is driven by gas, without arc and spark, and is completely used in places with flammable and explosive liquids or gases.
  5. Simple maintenance: Compared with other air-driven pumps, booster pumps can do the same work, but with fewer parts and seals, easy maintenance
  6. High cost performance: The booster pump is a plunger pump. When working, the booster pump reciprocates rapidly. As the output pressure increases, the reciprocation of the pump slows down until it stops. At this time, the pressure of the pump is constant and the energy consumption is the lowest. All parts stop moving.

Air Driven Gas Booster Pump Composition and principle

  1. Gas part This part is composed of a lightweight different-diameter piston equipped with O-ring seals and a sleeve with outer glass fiber winding or duralumin coating and epoxy resin filling in the middle, and the piston is placed in the sleeve. The diameter of this air piston is constant for any series of air pumps. When compressed air is fed into the pneumatic device, the piston is forced into the compression stroke, and then the air drives the piston back for the suction stroke (except for M series pumps with spring automatic return function). Unlike many other pumps, pneumatic lines do not require the use of lubricants due to the inherently low-friction nature of the design and lubrication during assembly.
  2. Hydraulic part
    The piston/punch rod of the hydraulic device is directly connected with the piston, and its lower end is loaded into the housing of the hydraulic device. Its diameter determines the compression ratio of the pump and thus the output flow and maximum pressure. Its function is to draw liquid through the inlet control valve and let it flow out through the outlet control valve under higher pressure. The unit is equipped with a spring check valve to control the flow of liquid in and out of the channel. When the piston/ram of the hydraulic unit is on the suction stroke, the inlet control valve opens and the outlet control valve is held closed by a spring to introduce liquid into the pump. During the boost stroke, the inlet control valve is closed and the piston/ram of the hydraulic unit forces fluid out through the outlet control valve. The dynamic seal is located around the piston/ram of the hydraulic unit and is a virtually wear-free part. Its function is to contain liquid under pressure during cycling and prevent external leakage or infiltration of gas installations. According to the medium of the pumped liquid, the operating temperature and the boost ratio, different sealing materials and forms are selected. NOTE: Most pumps use a spacer between the pneumatic and hydraulic sections to allow for complete separation and contamination-free operation.
  3. Air circulation valve
    This section consists of a controller and a plunger that causes compressed air to flow to either end of the air piston depending on the position status. The piston pushes the control valve at the upper and lower ends of its stroke to alternately pressurize and ventilate the large area of the slide valve to control the reciprocating movement of the air flow to the air piston to maintain a circulating state. When the air is exhausted from the pump, it needs to pass through the exhaust muffler. Unlike many other pumps, the pump is not designed with a metal-to-metal tight fit, which prevents air leaks that would cause the plunger to cease operation.

Air Driven Gas Booster Pump Selection method

  1. What is the pressurized medium?
    Pneumatic gas booster pumps are divided into gas booster pumps and gas-liquid booster pumps. The working principles of the two pumps are the same, but there are differences in structure. The gas booster pump is suitable for the boosting of clean compressed air and high-purity gas, and the gas-liquid booster pump is suitable for water, hydraulic oil, kerosene and other liquids with less impurities and low viscosity. Different media need to choose different seals to suit.
  2. Where to use it?
    Pneumatic gas booster pumps are suitable for occasions with high pressure and small flow, suitable for scientific research, testing, testing and other occasions, but not suitable for civil and large flow output occasions.
  3. How much traffic?
    Especially for gas pressurization, gas is divided into standard flow and working state flow. Generally speaking, everyone talks about standard flow.
  4. What is the inlet pressure of the pressurized medium?
    Gas-liquid booster pumps generally have no requirement for the inlet pressure of the liquid. Most gas booster pumps require a certain pre-pressure of the gas. The size of the pre-pressure will determine whether to use a single-stage gas booster pump or a two-stage gas booster pump first. Pump.
  5. Is there compressed air on site?
    Pneumatic booster pumps are driven by compressed air, and compressed air is the key. Choosing a different pump will determine the compressor with a large displacement.
