Gas-liquid booster pump working principle:

　　先将增压泵内充满液体，然后启动离心泵，叶轮快速转动，叶轮的叶片驱使液体转动，液体转动时依靠惯性向叶轮外缘流去，同时叶轮从吸入室吸进液体，在这一过程中，叶轮中的液体绕流叶片，在绕流运动中液体作用一升力于叶片，反过来叶片以一个与此升力大小相等、方向相反的力作用于液体，这个力对液体做功，使液体得到能量而流出叶轮，这时液体的动能与压能均增大。

　　Will be filled with liquid booster pump first, and then start the centrifugal pump, the impeller rapid rotation, the impeller blades driven liquid, liquid to rely on the rotation inertia to the flow of the impeller outer edge and at the same time from the suction chamber impeller sucked into liquid, in the process, of fluid flow in the impeller blade, in the flow around liquid a lift to the blade, which in turn leaves with a lift with the equal and opposite force used in liquid, the force of fluid power, causes the liquid energy and flow impeller, then the kinetic energy of the liquid and the pressure can be increased.

　　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。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。

　　Supercharger gas-liquid booster pump working principle is similar to the pressure, air of big diameter driven piston of a low pressure, when the pressure is applied to a small area of the piston in, create a high pressure. Through a two five ventilation control reversing valve, booster pump can achieve continuous operation. Controlled by the one-way valve pushing liquid discharge, high pressure plunger pump outlet pressure size is related to air driven pressure. When driving part and output liquid pressure balance between the pump will stop running, no longer consumes the charge of air. When the output pressure drop or air driven pressure increases, the pump will automatically start to run, until to achieve pressure balance again after automatic stop.

　　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优质产品，从而保证了德科气液增压泵的性能。一般泵都有进气、排气两个口，在进气口能产生低于常压（即大气压）气压的叫“负压”；在排气口能产生高于常压气压的叫“正压”；比如常说的真空泵就是负压泵，增压泵就是正压泵。正压泵跟负压泵有很大的不同。比如气体流向，负压泵是外部气体被吸入到抽气嘴；正压是从排气嘴喷出去；比如气压的高低等。

　　With one pneumatic non-equilibrium gas distributing valve to realize the automatic reciprocating motion of the pump, the pump body gas drive part adopts aluminum alloy manufacture. After hydraulic parts according to different media carbon steel or stainless steel, the complete set of the pump seals are imported high quality products, to ensure the performance of the deco gas-liquid booster pump. General pump has two mouth, intake and exhaust in the air inlet can produce below atmospheric pressure (atmospheric pressure) is called "negative pressure"; The vent can produce higher than atmospheric pressure is called "positive pressure"; Such as is often said that the vacuum pump suction pump, booster pump is a positive pressure pump. Positive pressure and negative pressure pump is very different. Such as gas flow, negative pressure pump is an external gas drawn into the suction mouth; Positive pressure from exhaust nozzle spray out; Such as pressure of high and low, etc.
