耐腐蚀真空泵是根据国际标准并结合非金属泵工艺设计制造的。适用于强酸、强碱、盐、强氧化剂等各种腐蚀性介质的长期运输。它的外壳由内衬聚全乙丙烯(FEP)的金属外壳制成，所有过流部件由塑料合金(聚四乙烯，FEP)制成。

耐腐蚀真空泵结合了各种塑料泵的优点，耐腐蚀性强，耐磨性好，机械强度高。真空泵适用于没有固体颗粒的介质。它的介质温度0℃~120℃，入口压力不大于2kg/cm2。那么真空泵的工作原理是怎样的呢？

耐腐蚀真空泵的工作原理是，当泵内充满水时，叶轮旋转产生离心力，叶轮通道内的水被甩向外边，在作用的离心力作用下面流入泵壳，于是叶轮中间的压力降低，低于进水管内的压力，水在作用的压差作用下从吸水池流入叶轮。这样水泵就可以持续吸水供水。

除了叶轮的作用，螺旋泵壳的作用也很重要。从叶轮获得能的液体流出叶轮时有很大的作用。液体被收集在螺旋泵壳中，动能在后扩散管中转化为压力能。与其他类型的泵相比，耐腐蚀真空泵具有结构简单、磨损小、运行稳定、噪音低、出水均匀、调节方便、效率高的优点，因此化学真空泵得到了广泛的应用。

Corrosion resistant vacuum pump is designed and manufactured according to international standards and combined with non-metallic pump process. It is suitable for long-term transportation of strong acid, strong alkali, salt, strong oxidant and other corrosive media. Its shell is made of metal shell lined with FEP, and all flow passage parts are made of plastic alloy (FEP).

The corrosion-resistant vacuum pump combines the advantages of various plastic pumps, with strong corrosion resistance, good wear resistance and high mechanical strength. Vacuum pump is suitable for medium without solid particles. Its medium temperature is 0 ℃ ~ 120 ℃, and its inlet pressure is not more than 2kg / cm2. So how does the vacuum pump work?

The working principle of corrosion-resistant vacuum pump is that when the pump is full of water, the impeller rotates to produce centrifugal force, and the water in the impeller channel is thrown to the outside. Under the action of centrifugal force, the water flows into the pump shell, so the pressure in the middle of the impeller is lower than that in the inlet pipe, and the water flows into the impeller from the suction tank under the action of the differential pressure. In this way, the pump can continuously absorb water and supply water.

In addition to the role of the impeller, the role of spiral pump housing is also very important. The liquid that can get energy from the impeller has a great effect when it flows out of the impeller. The liquid is collected in the screw pump shell, and the kinetic energy is converted into pressure energy in the rear diffuser. Compared with other types of pumps, the corrosion-resistant vacuum pump has the advantages of simple structure, small wear, stable operation, low noise, uniform water discharge, convenient adjustment and high efficiency, so the chemical vacuum pump has been widely used.
