Description

Technical Field

[0001] The utility model relates to the technical field of vacuum units, in particular to a Roots water ring vacuum unit with a cooling device. Background Technique

[0002] The Roots water ring vacuum unit is a vacuum device that combines the advantages of a Roots pump and a water ring pump and is widely used in various industrial fields. The working principle of the Roots water ring vacuum unit is based on the combination of the working principles of the Roots pump and the water ring pump. The Roots pump is a positive displacement vacuum pump. Through the rotation of two meshing rotors in the pump cavity, gas is sucked in from the intake port, compressed and then discharged. The water ring pump uses the interaction between the water ring and the impeller to suck in gas from the intake port and reach a vacuum state through the compression and discharge process. The Roots water ring vacuum unit combines these two pumps and realizes efficient vacuum extraction through the rapid air extraction of the Roots pump and the higher vacuum degree of the water ring pump.

[0003] During the operation of the existing Roots vacuum pump, due to mechanical friction, gas compression and the interaction of internal components, a large amount of heat will be generated. If there is no effective cooling device to dissipate this heat, the temperature of the pump body will rise rapidly, which may cause the lubricating oil in the pump to overheat and deteriorate, the bearings and other mechanical components to wear more severely due to high temperature, and even may cause component deformation or fracture due to thermal stress, thus damaging the pump body. At the same time, long-term operation in a high-temperature environment will accelerate the aging and wear of the internal components of the Roots vacuum pump, thus shortening the overall service life of the pump. In particular, the lubricating oil is prone to oxidation and deterioration at high temperature, losing its lubricating and cooling functions, and greatly reducing the protection effect on the pump. Therefore, it is necessary to design a Roots water ring vacuum unit with a cooling device to cool the vacuum unit. Content of the Utility Model
