高压自能式SF6断路器是近年来开发的一种基于较新灭弧方式的产品。自能式灭弧室在开断过程中通过电弧的加热，使灭弧室内的气体压力增加，产生足够的压力吹弧。电弧加热气体的方式可以减小灭弧室的体积并且降低操动机构的操作功，使开断过程更加稳定可靠[1-2]。对于灭弧室来说，气吹的压力是一个很重要的参数，直接影响灭弧室的开断能力。

The pump body consists of suction chamber, liquid storage chamber, turbination chamber, liquid return port, gas-liquid separation chamber, etc. After the pump starts normally, the impeller will suck the liquid in the suction chamber and the air in the inlet line so that the both can mix fully in the impeller. Due to the centrifugal force, the liquid along with the gas flows towards the outer edge of the turbination chamber and then a belt of white foam with a certain thickness and a liquid ring with high-speed rotation come into being on the outer edge of the impeller.
