气液增压器与气液增压泵，原理都是大活塞推动小活塞，由于面积差，使液体压力放大，F=但两个的本质区别在于，气液增器一般为单个往复运动，不连续运动，进出口没有单向阀，外挂油杯，一般用压力脉冲，冲压等场合；气液增压泵能依靠自身的换向阀，接通压缩空气连续往复运动，进出口装有单向阀，出液连续，一般用于压力检测。
The principle of gas-liquid booster and gas-liquid booster pump is that a large piston pushes a small piston, and due to the area difference, the liquid pressure is amplified. F=, but the essential difference between the two is that the gas-liquid booster generally moves in a single reciprocating motion, discontinuous motion, without a one-way valve at the inlet and outlet, with an external oil cup, and generally uses pressure pulse, stamping, and other occasions; The gas-liquid booster pump can rely on its own directional valve to connect compressed air for continuous reciprocating movement. The inlet and outlet are equipped with one-way valves, and the liquid output is continuous. It is generally used for pressure detection.
气体增压泵利用大面积活塞端的低压气体驱动而产生小面积活塞端的高压流体。可用于压缩空气及其它气体，输出气压可通过驱动气压无级调节。输出流量大：只需0.3-0.8MPa压缩空气驱动就可获得较大的输出流量工作时，迅速往复工作，随着输出压力接近设定压力值时泵的往复运动速度减慢直停止。并保持这个压力，此时消耗能量很小，无热气体增压泵量产生，无零件运动。当压力平衡打破后，气动增压泵自动开始工作到下一个平衡。
The gas booster pump utilizes low-pressure gas at the large piston end to drive and generate high-pressure fluid at the small piston end. It can be used to compress air and other gases, and the output pressure can be steplessly adjusted by driving the pressure. Large output flow rate: A large output flow rate can be achieved by driving with only 0.3-0.8MPa compressed air. When working, the pump quickly reciprocates, and as the output pressure approaches the set pressure value, the reciprocating motion speed of the pump slows down until it stops. And maintain this pressure, at which point the energy consumption is very small, there is no hot gas booster pump generated, and there is no component movement. When the pressure balance is broken, the pneumatic booster pump automatically starts working to the next balance.
材质高压部分材质为不锈钢。高压柱塞材质为不锈钢，并采用双层密封。维护简单气动增压泵的零件及密封少，维护简单且成本低。相同系列泵的所有"O"型圈，维修包易损部件可相互替换，大大降低了维修成本。气动增压泵出厂前已加注润滑剂，工作时无需外部润滑。
The high-pressure part is made of stainless steel with excellent material. The high-pressure plunger is made of stainless steel and adopts a double layer seal. The maintenance of the pneumatic booster pump is simple, with fewer parts and seals, and low cost. All "O" rings and vulnerable parts of the same series of pumps can be replaced with each other in the repair kit, greatly reducing maintenance costs. The pneumatic booster pump has been lubricated before leaving the factory, and does not require external lubrication during operation.
