气动增压泵分为气液增压泵，气体增压泵气液增压泵原理是利用大面积活塞的低气压发生小面积活塞的高液压。
Pneumatic booster pump is divided into gas-liquid booster pump. The principle of gas-liquid booster pump is to use low pressure of large area piston to produce high hydraulic pressure of small area piston.
电动泵，即用电驱动的泵，电动泵是由泵体、扬水管、泵座、潜水电机(包括电缆)和起动保护装置等组成。泵体是潜水泵的作业部件，它是由进水管、导流壳、逆止阀、泵轴和叶轮等零部件组成，叶轮在轴上的固定有两种方式。
Electric pumps, that is, electric-driven pumps, electric pumps are composed of pump body, riser, pump seat, submersible motor (including cable) and starting protection device. Pump body is the working part of submersible pump. It is composed of intake pipe, diversion shell, check valve, pump shaft and impeller. There are two ways to fix impeller on the shaft.
气动增压泵与电动泵比较具有哪些长处呢
What are the advantages of pneumatic booster pump compared with electric pump?
1、 可保持在任何预订压力下，不再消耗能量和发生热量不发生热量，不会有火花和火焰风险
1. Can be maintained under any reservation pressure, no energy consumption and heat generation, no heat generation, no spark and flame risk.
2、容易应用于自动控制系统中
2. Easy to apply in automatic control system
3、接连启停，不受限制，并无不良影响
3. Continuous start-stop without restriction and without adverse effects
4、压力线性输出，容易人工控制
4. Linear output of pressure, easy manual control
5、轻便牢靠，易于保护，坚固耐用
5. Light and reliable, easy to protect, strong and durable
6、以压缩空气为动力源，不需运用电源
6. Using compressed air as power source, no power source is needed.
7、运转时无油润滑。
7. No oil lubrication during operation.
8、达7000bar的增压才能，满足大多数高压需要
8. Supercharging capacity up to 7000bar to meet most high pressure requirements
气动活塞环及其他气动部件在作业状态时不需要添加润滑油，节省运转成本，并可防止油气污染环境
Pneumatic piston rings and other pneumatic components do not need to add lubricating oil during operation, which saves operation cost and prevents oil and gas from polluting the environment.
