气液增压泵之工作原理
气液增压泵工作原理:
Working principle of gas-liquid booster pump:
气液增压泵是以气体为动力源的一种往复式柱塞泵,利用大面积活塞端的低压气体驱动面转换为小面积活塞端的高压液体,增压比决定泵的最大输出压力。
Working principle of gas-liquid booster pump: gas-liquid booster pump is a reciprocating plunger pump with gas as the power source. It USES the low-pressure gas driving surface of large-area piston end to convert into high-pressure liquid of small-area piston end. The pressurization ratio determines the maximum output pressure of the pump.
工作时,当驱动活塞向后运行时,将液体吸入泵内,此时入口处的单向阀打开,出口单向阀关闭;当活塞向前运行时,在液体一侧会形成一定压力,压力会将入口处单向阀关闭,出口处单向阀打开,高压液体就从出口处流出。
When working, when driving the piston running backwards, the liquid into the pump, at this time the inlet one-way valve open, the outlet one-way valve closed;As the piston moves forward, a certain pressure is created on the liquid side, which closes the inlet one-way valve and opens the outlet, and the high-pressure liquid flows out of the outlet.
气液增压泵能够实现自动循环,当出口压力升高时,泵会减速运行,并对活塞产生一定的阻力,当力平衡时,泵会自动停止运行,此时高压活塞端压力与液压力达到平衡,活塞保持静止,此时能量消耗最低,无油温之困扰,各部件停止工作。当出口压力降低或气体驱动压力增加时,液泵会自动启动运行。
Gas-liquid booster pump can achieve automatic cycle, when the outlet pressure rises, the pump will slow running, and the piston produces a certain resistance, when the force balance, the pump will stop running automatically, the high pressure piston side pressure and hydraulic pressure balance, piston remain at rest, the lowest energy consumption at this time, of the oil temperature, components to stop working.When the outlet pressure decreases or the gas driving pressure increases, the liquid pump will start running automatically.
