气液增压泵是由压缩空气来驱动，增压液体，又称气动液体增压泵，可以将液体增压到640Mpa的压力。压力无极可调，方便控制。保压的时候不消耗能量。便于携带，可以用于防爆领域。下面来讲讲气液增压泵的原理以及特点吧。
The gas-liquid booster pump is driven by compressed air to pressurize the liquid, also known as the pneumatic liquid booster pump, which can pressurize the liquid to a pressure of 640mpa. The pressure is infinitely adjustable and easy to control. No energy is consumed during pressure maintaining. It is easy to carry and can be used in explosion-proof field. Let's talk about the principle and characteristics of the gas-liquid booster pump.
气液增压泵的原理
Principle of gas-liquid booster pump
气液增压泵工作原理类似于压力增压器，对大径空气驱动活塞施加一个很低的压力，当此压力作用于一个小面积活塞上时，产生一个高压。通过一个二位五通气控换向阀，增压泵能够实现连续运行。
The working principle of the gas-liquid booster pump is similar to that of the pressure booster, which applies a very low pressure to the large-diameter air driven piston. When this pressure acts on a small area piston, a high pressure will be generated. Through a two position five ventilation control reversing valve, the booster pump can realize continuous operation.
由单向阀控制的高压柱塞不断的将液体排出，增压泵的出口压力大小与空气驱动压力有关。当驱动部分和输出液体部分之间的压力达到平衡时，增压泵会停止运行，不再消耗空气。
The high-pressure plunger controlled by the one-way valve continuously discharges the liquid. The outlet pressure of the booster pump is related to the air driving pressure. When the pressure between the drive part and the output liquid part reaches equilibrium, the booster pump will stop running and no longer consume air.
当输出压力下降或空气驱动压力增加时，增压泵会自动启动运行，直到再次达到压力平衡后自动停止。
When the output pressure drops or the air drive pressure increases, the booster pump will automatically start and run until the pressure balance is reached again and then stop automatically.
采用单气控非平衡气体分配阀来实现泵的自动往复运动，泵体气驱部分采用铝合金制造。接液部分根据介质不同选用碳钢或不锈钢，泵的全套密封件均为进口产品，从而保证了气液增压泵的性能。
The single gas control non-equilibrium gas distribution valve is used to realize the automatic reciprocating movement of the pump. The gas drive part of the pump body is made of aluminum alloy. Carbon steel or stainless steel is selected for the liquid receiving part 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.
气液增压泵的特点
Characteristics of gas-liquid booster pump
1、输出压力高，大输出压力可高达400Mpa。
1. High output pressure, large output pressure can be as high as 400MPa.
2、使用范围广，工作介质可为液压油、水及大部分化学腐蚀性（相应的耐腐蚀材质密封）液体，并且可靠性高，免维护和寿命长。
2. It can be used in a wide range. The working medium can be hydraulic oil, water and most of the chemically corrosive (corresponding corrosion-resistant materials are sealed) liquids. It has high reliability, maintenance free and long service life.
3、易于调节，在泵的压力范围内，调节调压阀从而调节输入气压，输出液压相应得到无级调整。
3. It is easy to adjust. Within the pressure range of the pump, adjust the pressure regulating valve to adjust the input air pressure, and the output hydraulic pressure can be adjusted steplessly accordingly.
4、自动保压，无论何种原因造成保压回路压力下降，泵将自动启动，补充泄漏压力，保持回路压力稳定。
4. Automatic pressure maintaining: no matter what causes the pressure of the pressure maintaining circuit to drop, the pump will start automatically to supplement the leakage pressure and keep the circuit pressure stable.
5、操作，采用气体驱动，无电弧及火花，可在危险场所使用。
5. Safe operation, gas driven, no arc and spark, can be used in dangerous places.
The application of gas-liquid booster pump is also very wide, such as aviation industry, automobiles industry, tunnel engineering, etc. if you have any needs, please come to our website http://www.feileisi.com Consult for more information!
