气液增压泵电机的使用特点

先将增压泵电机内充满液体,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。
First, the motor of the booster pump is filled with liquid, then the centrifugal pump is started. The impeller rotates rapidly. The impeller blade drives the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller by inertia. At the same time, the impeller sucks the liquid from the suction chamber. In turn, the blade acts on the liquid with a force equal to and opposite to the lift. This force works on the liquid, so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.
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,增压泵电机会自动启动运行,直到再次达到压力平衡后自动停止。
气体增压泵
The gas-liquid booster pump works like a pressure supercharger, exerting a very low pressure on a large diameter air-driven piston, which produces a high pressure when applied to a small area of the piston. Through a two position five ventilation control reversing valve, the booster pump can run continuously. The high-pressure plunger controlled by 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 driving part and the output liquid part reaches a balance, the booster pump will stop running and no longer consume air. When the output pressure drops or the air drive pressure increases, the motor of the booster pump will start up automatically until it reaches the pressure balance again and 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。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。
The single pneumatic nonequilibrium 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. The liquid connection part is carbon steel or stainless steel according to the medium. Generally, there are two intake and exhaust ports in the pump, the intake can produce less than atmospheric pressure (atmospheric pressure) called "negative pressure"; in the exhaust can produce higher than atmospheric pressure called "positive pressure"; for example, often said that the vacuum pump is a negative pressure pump, booster pump is a positive pressure pump. The positive pressure pump is very different from the negative pressure pump. For example, the direction of gas flow, negative pressure pump is the external gas is sucked into the exhaust nozzle; positive pressure is from the exhaust nozzle out; such as the level of air pressure.
