Problems solved by technology

[0003] At present, most of the vacuum pumps on the market will increase the air pressure of the exhaust part when they are operated for a long time. The exhaust quality of the body, the motor will increase the force to exhaust the vacuum pump, which will lead to a further increase in the air pressure at the end of the vacuum pump. It is particularly important to decompress the vacuum pump

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to a vacuum pump decompression device. Background technique [0002] A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space. According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries. [0003] At present, most of the vacuum pumps on the market will increase the air pressure of the exhaust part when they are operated for a long time. The exhaust quality of the body, the motor will increase the force to exhaust the vacuum pump, which will ...
