气液增压缸和气液增压泵在生产原理上有哪些不一样?

1、气液增压缸工作原理:是将一油压缸与增压器作一体式相分离,应用增压器的大小不同受压截面面积之比,以及帕斯卡能源守衡原理而工作。
1. The working principle of the gas-liquid supercharger cylinder is to separate an oil cylinder from the supercharger in one body, and to work by applying the ratio of the size of the supercharger to the area of different compression sections and Pascal's energy conservation principle.
由于压力不变,当受压面积由大变小时,则压强也会随大小不同而变化的原理,从而到达将气压压力进步到数十倍的压力效果,以预压式增压缸为例:当工作气压压在液压油(或活塞)外表时,液压油会紧缩空气作用而流向预压行程腔,此时液压油会疾速推进式件作位移,当工作位移遇到阻力大于气压压力时缸则中止动作,此时,增压缸的增压腔由于电信号(或气动信号)动作,开端增压从而到达成型产品的目的。
Because the pressure does not change, when the pressure area changes from large to small, the pressure will also change with the size of the principle, so as to achieve the pressure effect of increasing the pressure pressure to tens of times. Take the pre-pressurized cylinder as an example: when the working pressure is on the surface of the hydraulic oil (or piston), the hydraulic oil will compress the air and flow to the pre-pressurized travel chamber, and then the hydraulic oil will rapidly advance the components. For displacement, when the working displacement meets resistance greater than the pressure, the cylinder stops working. At this time, the booster chamber of the booster cylinder starts to boost because of the action of electric signal (or pneumatic signal) so as to achieve the purpose of forming the product.
2、气液增压泵工作原理:
2. The 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,应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,增压比决议泵的最大输出压力。
Gas-liquid booster pump is a reciprocating piston pump with gas as its power source. The low-pressure gas driving surface of large area piston end is used to convert into high-pressure liquid of small area piston end. The boost ratio determines the maximum output pressure of the pump.
工作时,当驱动活塞向后运转时,将液体吸入泵内,此时入口处的单向阀翻开,出口单向阀关闭;当活塞向前运转时,在液体一侧会构成一定压力,压力会将入口处单向阀关闭,出口处单向阀翻开,高压液体就从出口处流出。
气体增压泵
When the piston is driven backward, the liquid is sucked into the pump. At this time, the one-way valve at the inlet opens and the one-way valve at the outlet closes. When the piston is running forward, a certain pressure will be formed on the liquid side. The pressure will close the one-way valve at the inlet and turn the one-way valve at the outlet, and the high-pressure liquid will flow out from the outlet.
气液增压泵可以完成自动循环,当出口压力升高时,泵会减速运转,并对活塞产生一定的阻力,当力均衡时,泵会自动中止运转,此时高压活塞端压力与液压力到达均衡,活塞坚持静止,此时能量耗费最低,无油温之搅扰,各部件中止工作。当出口压力降低或气体驱动压力增加时,液泵会自动启动运转。
The pneumatic-hydraulic booster pump can complete the automatic cycle. When the outlet pressure rises, the pump will slow down and produce certain resistance to the piston. When the force equalizes, the pump will automatically stop running. At this time, the pressure and hydraulic pressure of the high-pressure piston end reach equilibrium, and the piston is still. At this time, the energy consumption is the lowest, there is no disturbance of oil temperature, and the components stop working. When the outlet pressure decreases or the gas driving pressure increases, the pump will start automatically.
