Liquid ring vacuum pump structure
Liquid ring vacuum pump is mainly used for the formation of rough vacuum. Because of its close isothermal compression, insensitive to dust, inhaled gas can be entrained with liquid or a large number of water vapor, etc., in the power, petrochemical, pharmaceutical, paper and other fields are widely used. In most applications, the liquid ring vacuum pump to work as a working fluid, people used to call it a water ring vacuum pump. There are many different configurations in all liquid ring vacuum pump products on the market. â‘ by suction, exhaust parts structure divided into cone pump and flat pump. â‘¡ divided by the impeller series, can be divided into single-stage pump and two-stage pump. Among them, cone pumps and flat pump have a single-stage impeller and two-stage impeller structure. â‘¢ according to the impeller per rotation of a week to complete suction, exhaust process points can be divided into single-action and double-acting vacuum pump. In the above several different structure of the vacuum pump, each pump is by the pump shaft, pump body, side cover, impeller, distributor plate (plate pump) or distributor (cone pump), shaft seal components, bearing components . Parts exposed to the working medium during work are called overcurrent parts, and the remaining parts are called non-overcurrent parts.
