增压泵气动类的工作原理及应用范围是什么?

气体增压泵的原理类似于气动压力增压器,对空气驱动的大活塞直接施加一个很小的压力(如:气体活塞3),当此压力作用一个很小面积的高压活塞(高压活塞2)上面时,产生一个高压,通过一个二位四通阀(滑阀4)气体增压泵可以实现连续运行,换向阀滑阀使驱动气体交替作用于活塞的底部及顶部表面,通过二位二通阀(先导阀7)来控制滑阀,先导阀有空气驱动气压来控制,进行填充或排空滑阀室。
The principle of the gas booster pump is similar to the pneumatic pressure booster, which directly applies a small pressure (such as gas piston 3) to the large air driven piston. When this pressure acts on a small area of high-pressure piston (high-pressure piston 2), a high pressure is generated, and the continuous operation of the gas booster pump can be realized through a two position four-way valve (slide valve 4), The slide valve of the directional valve makes the driving gas act alternately on the bottom and top surfaces of the piston. The slide valve is controlled by the two position two-way valve (pilot valve 7). The pilot valve is controlled by air driving air pressure to fill or empty the slide valve chamber.
由单向阀(入口单向阀和出口单向阀1)控制的高压活塞不断地将气体排出,气体增压泵的出口压与驱动气压力有关,根据气动增压泵的相对应计算公式可以计算出输出压力的数值。
The high-pressure piston controlled by the check valve (inlet check valve and outlet check valve 1) continuously discharges the gas. The outlet pressure of the gas booster pump is related to the driving gas pressure. The value of the output pressure can be calculated according to the corresponding calculation formula of the pneumatic booster pump.
当气体部分与驱动部分的压力平衡时,增压泵不再运动,也就不再消耗空气。当输出压力下降或空气驱动气压增压时候,增压泵会自启动,直到压力平衡后自动停止。那么除此之外,通过控制驱动开关,电接点式压力表或外部控制器可以实现菲恩特泵的自动启停。
When the pressure of the gas part and the driving part is balanced, the booster pump no longer moves and no air is consumed. When the output pressure drops or the air driven air pressure is pressurized, the booster pump will start automatically until the pressure is balanced and stop automatically. In addition, the automatic start and stop of feiente pump can be realized by controlling the drive switch, electric contact pressure gauge or external controller.
