一、气体增压泵和气液增压缸之工作原理不同:

1、 The working principle of gas booster pump and gas-liquid booster cylinder is different:

1、气体增压泵工作原理;这种以压缩空气为动力源的活塞式增压泵，当进气时增压气控阀的阀芯往复切换工作，控制增床代活塞以极快的速度作往复动作，随着输出压力增大，活塞往复速度减慢直到停止。此时，增压代输出压力达到恒定，能量消耗达到，各部件停止工作;而且无论由于什么原因导致保压回路压力下降，增压阀都会自动启动，补充泄漏压力，保持回路压力恒定。

1. Working principle of gas booster pump; This type of piston type booster pump, powered by compressed air, switches the valve core of the booster control valve back and forth when entering the air, controlling the bed to replace the piston to perform reciprocating action at an extremely fast speed. As the output pressure increases, the reciprocating speed of the piston slows down until it stops. At this point, the output pressure of the booster reaches a constant level, energy consumption reaches its minimum, and all components stop working; Moreover, regardless of the reason for the decrease in pressure in the pressure maintaining circuit, the booster valve will automatically start to supplement the leakage pressure and maintain a constant circuit pressure.

2、气液增压缸工作原理:气液增压缸是将一油压缸与增压器作一体式相结合，利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。因为压力不变，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，从而达到将气压压力提高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)表面时，液压油会压缩空气作用而流向预压行程腔，此时液压油会讯速推动式件作位移，当工作位移遇到阴力大干气压压力时缸则信止动作，此时，增压缸的增压腔因为电信号(或气动信号)动作，开始增压从而达到成型产品的目的。

2. Working principle of gas-liquid booster cylinder: The gas-liquid booster cylinder is a combination of an oil pressure cylinder and a booster, which works by utilizing the ratio of different compression cross-sectional areas of the booster and the Pascal energy conservation principle. Because the pressure remains constant, when the compression area changes from large to small, the pressure will also change with different sizes, thus achieving the pressure effect of increasing the air pressure to tens of times. Taking the pre compression booster cylinder as an example: when the working air pressure is pressed on the surface of the hydraulic oil (or piston), the hydraulic oil will compress the air and flow to the pre compression stroke chamber. At this time, the hydraulic oil will quickly push the displacement of the component, When the working displacement encounters the pressure of negative pressure and dry air pressure, the cylinder will stop working. At this time, the boosting chamber of the boosting cylinder will start boosting due to the action of electrical signals (or pneumatic signals) to achieve the purpose of forming the product.
