The booster pump uses low pressure gas (2-8 bar) of large area piston to drive high pressure gas/liquid on small area piston. Can be used to compress air and other gases, the output air pressure can be adjusted steplessly by driving air pressure. Gas pipeline booster pumps have single acting pumps and double acting pumps. The double-acting pump piston compresses the gas in both reciprocating strokes. Then, the following Xiao Bian introduced the principle of the booster pump and the characteristics of the booster pump.
Booster pump principle
When the booster pump is running, the pressure will gradually rise to the set upper limit value. When the upper limit value is reached, the booster pump will be powered off and stop running; when the booster pump stops running and the pipe network user continues to use water, The water pressure in the pipe network will drop to the set lower limit value and the booster pump will be powered on again when the switch is triggered. The operation of the reciprocating cycle realizes the automatic water supply function of the traditional automatic booster pump. We know that in addition to industrial water, the general amount of water is always large or small. If the traditional booster pump control mechanism is used, it will inevitably cause the booster pump to start and stop frequently. Frequent start and stop will easily burn out the motor and control components. The indirect influence of the user is the pressure of one or two small water pressures (the biggest influence is the water heater is cold and hot). Obviously, with the current material conditions and people's consumption concepts, traditional pressure differential automatic booster pumps are increasingly unable to meet actual needs.
Booster pump features
1, simple maintenance: Booster pump parts and seal, maintenance is simple and low cost with repressurization.
2, cost-effective: booster pump with high output performance and low cost features.
3, strong adjustability: booster pump output pressure and flow are driven by the gas pressure regulator valve accurately adjusted.
4. Adjust the drive air pressure so that the output pressure of the air pressure pipeline booster pump is accurately adjusted between the pre-increase pressure and the maximum output pressure.
5. High output pressure: The maximum working pressure of the pneumatic liquid pipeline booster pump can reach 700Mpa, and the maximum working pressure of the pneumatic gas pipeline booster pump can reach 300 Mpa.
6, good material: high pressure pump material is hard aluminum alloy. The high pressure plunger is made of stainless steel. And use double seal. The key parts can be selected according to the medium system.
7, a variety of gas drive: compressed air, nitrogen, water vapor and so on.
8, the output flow rate: pneumatic pipe booster pump only 0.2-0.8Mpa compression empty. All "O" rings of the same series of pumps, the vulnerable parts of the repair kit can be replaced with each other, greatly reducing maintenance costs. Pneumatic pipeline booster pumps do not require lubricants.
9. Flexible application: The booster pump can be used from simple manual operation to fully automatic operation. The booster pump is suitable for various application fields and is compatible with the customer's system. Most models of pump air motors in the same series are interchangeable.
10. Automatic pressure keeping: In operation, the booster pump reciprocates quickly. As the output pressure approaches the set pressure value, the reciprocating speed of the pump decreases until it stops. And maintain this pressure, at this time the energy consumption is very small, no heat is generated, no parts move. When the pressure balance breaks the booster pump automatically starts working to the next balance.
Booster pump classification
1, gas liquid booster pump
The gas-liquid booster pump works like a pressure booster and applies a very low pressure to a large-diameter air-driven piston. When this pressure acts on a small-area piston, a high pressure is generated. Through a two-position five-vent control reversing valve, the booster pump can achieve continuous operation. The high-pressure plunger controlled by the one-way valve constantly discharges the liquid, and the pressure of the booster pump outlet is related to the air-driven pressure. When the pressure between the drive section and the output liquid section is balanced, the booster pump stops and no longer consumes air. When the output pressure decreases or the air drive pressure increases, the booster pump will automatically start running until the pressure balance is automatically stopped again. The single-control non-equilibrium gas distribution valve is used to realize the automatic reciprocating motion of the pump. The pump body is used in the air drive. Made of aluminum alloy. The wetted part adopts carbon steel or stainless steel according to different media. The whole set of seals of the pump are imported high quality products, thus ensuring the performance of the gas-liquid booster pump.
2, air booster pump
The principle of the air booster pump is to use a low pressure of a large area piston to produce a high hydraulic pressure of a small area piston. The air booster pump is used in the working environment where the original air pressure system is to increase the pressure, and can increase the air pressure of the working system to 2-5 times, and only the compressed air in the working system needs to be used as the air source. The pump is suitable for single-source pressurization. No power supply (can be used in areas where explosion protection is required). Within the pressure range of the pump, the regulator valve is adjusted to adjust the inlet pressure, and the output hydraulic pressure is correspondingly adjusted accordingly.
3, chlorine booster pump
Chlorine booster pumps have a wide operating pressure range. Different types of pumps can be used to obtain different pressure zones. Adjusting the input air pressure output pressure is adjusted accordingly. Extremely high pressure can be achieved, gas 90Mpa. With a wide range of flow rate, it can work smoothly for only 0.1Kg of air pressure for all types of pumps. At this time, the minimum flow rate can be obtained, and different flow rates can be obtained after adjusting the intake air amount. Easy to control, from simple manual control to full automatic control can meet the requirements.
Automatic restart, no matter what causes the pressure in the pressure keeping circuit to drop, it will restart automatically, supplement the leak pressure, keep the circuit pressure constant. Operating safety, using gas-driven, no arc and sparks, can be used in dangerous places.
