一、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。
A first liquid booster pump in full, and then start the fast rotating impeller, centrifugal pump, impeller blades driven by fluid rotation, the liquid is rotated by the inertia to flow to the outer edge of the impeller, the impeller from the suction chamber into the liquid at the same time, in this process, the liquid flow around the blade impeller, the flow around the liquid in the role in a lift in the leaves, leaves with a masterpiece in turn and the lift is equal and opposite to the force acting on liquid liquid, the liquid can be energy flow out of the impeller, the liquid kinetic energy and pressure energy were increased.
二、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。
Two, the air pressure booster pump works like a pressure booster, exerting a low pressure on the large diameter air driven piston, which produces a high pressure when the pressure is applied to a small area of the piston. Through a two position five directional control valve, the booster pump can achieve continuous operation. The high pressure plunger controlled by a one-way valve continuously discharges the liquid, and the pressure at the outlet of the booster pump is related to the air driving pressure. When the pressure between the driving part and the output liquid is balanced, the booster pump stops running and no longer consumes the air. When the output pressure drops or the air driving pressure increases, the booster pump will automatically start running and stop automatically until the pressure balance is reached again.
三、全自动气压消防增压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。
Three, automatic reciprocating automatic pressure fire booster pump can be realized by single gas control non-equilibrium gas distributing valve, pump gas flooding with Aluminum Alloy manufacturing. The liquid connection is made of carbon steel or stainless steel according to the medium. General pump intake and exhaust are two, lower than atmospheric pressure at the inlet can be called "negative pressure"; called "positive pressure" can produce higher atmospheric pressure in the exhaust port; for example, the vacuum pressure is often said pump, booster pump is positive pressure pump. The positive pressure pump is very different from the negative pressure pump. For example, the gas flow, the negative pressure pump is the external gas is sucked into the suction nozzle; positive pressure is from the exhaust nozzle jet; for example, the pressure level.
