Vacuum pump

Abstract

The invention particularly relates to a vacuum pump. The vacuum pump comprises a vacuum pump body and an impeller. The top of the vacuum pump body is connected with an air inlet pipe and an air outlet pipe. The top of the air inlet pipe is provided with an air inlet. The top of the air outlet pipe is provided with an air outlet. A pipe sleeve is arranged on the periphery of the air inlet pipe and the air outlet pipe in a sleeving mode. The lower end of the air inlet is connected with the upper end of a filtering mechanism. The filtering mechanism comprises a rubber ring and a filtering assembly. The filtering assembly comprises a first metal net layer, a phenolic paper element and a second metal net layer. A check valve is arranged at the lower end, close to the vacuum pump body, of the inlet pipe. A silencing mechanism is connected with the upper portion of the air outlet. The silencing mechanism sequentially comprises a pipe, silencing cotton and a metal plate from outside to inside. An outer shell is arranged on the periphery of the vacuum pump body in a sleeving mode. The pipe sleeve is provided with an opened plate. The outer wall of the vacuum pump body is connected with a thermometer. The thermometer is connected with an alarming device which is arranged on the outer side wall of the outer shell. The service life of the vacuum pump is greatly prolonged through the reasonable structural design.

Description

technical field [0001] The invention relates to the field of pumps, in particular to a vacuum pump. Background technique [0002] According to the working principle of vacuum pumps, vacuum pumps can be divided into two types: gas capture pumps and gas transmission pumps. vacuum In other words, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space. In the machinery manufacturing industry, a vacuum pump is an indispensable mechanical device, but the vacuum pump is in practice. There are the following deficiencies in the use process: In the actual production process, the vacuum pump still sucks dirty gas, and the heat of the pump is too high to cause the pump oil to solidify, which hinders normal work and reduces the service life of the vacuum pump. Contents of the invention [0003] In view of the above, the object of the present invention is to provide a vacuum pump to solve the problems in the prior art. ...
