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。那么气液增压泵的原理特点以及应用是怎样的？小编为您讲解下。
The gas-liquid booster pump is driven by compressed air. The pressurized liquid, also known as pneumatic liquid booster pump, can pressurize the liquid to 640Mpa. What are the principles, characteristics and applications of gas-liquid booster pump? I'll explain it to you.
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 is generated. The booster pump can realize continuous operation through a two position five vent control reversing valve.
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。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。
The high-pressure plunger controlled by the check valve continuously discharges the liquid, and 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 balance, the booster pump will stop running and no longer consume air. 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.
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 air control non-equilibrium gas distribution valve is used to realize the automatic reciprocating motion of the pump, and the gas drive part of the pump body is made of aluminum alloy. Carbon steel or stainless steel shall be selected for the liquid connection part according to different media. The full set of seals of the pump are imported 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. The output pressure is high, and the large output pressure can reach 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 has a wide range of applications. The working medium can be hydraulic oil, water and most of the chemically corrosive (corresponding corrosion-resistant material seals) liquids, and 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 drop in the pressure maintaining circuit, the pump will automatically start 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.
