The water ring vacuum pump is mainly used in the formation process of coarse vacuum. It is widely used in electric power, petrochemical industry, pharmaceutical industry, papermaking and other fields because of its advantages such as close to isothermal compression, insensitivity to dust, entrainment of liquid or large amount of water vapor by inhalation gas.
In most applications, water ring vacuum pump uses water as working fluid, which is often called water ring vacuum pump. Among all the water ring vacuum pump products on the market, there are many different structures.
① According to the structure of suction and exhaust parts, it can be divided into cone pump and flat pump
② According to the stages of impeller, it can be divided into single-stage pump and double-stage pump. Among them, the cone pump and the flat pump have a single-stage impeller and two-stage impeller structure.
③ According to the process of suction and exhaust completed by each rotation of impeller, it can be divided into single acting and double acting vacuum pumps.
In the above vacuum pumps with different structures, each pump is composed of pump shaft, pump body, side cover, impeller, distribution plate (flat pump) or distributor (cone pump), shaft seal parts, bearing parts, etc. In the process of working, the parts contacting the working medium are called over-current parts, and the other parts are called non over-current parts.
