Description
technical field [0001] The invention relates to a vacuum pump, in particular to an improved belt-type vacuum pump, belonging to the mechanical field. Background technique [0002] At present, there are various types of vacuum pumps. Ordinary mechanical vacuum pumps have low vacuum degree and high energy consumption. During the working process, the motor power required is large, the noise is high, and they are prone to failure. The vacuum pump needs to be maintained frequently after a period of use. Short, high maintenance cost, and the disassembly of the existing vacuum pump is cumbersome, and it is inconvenient to replace the parts in the pump body. Therefore, in order to solve the above problems, a new technical solution is specially provided to meet the needs of enterprises. Contents of the invention [0003] It is an object of the present invention to provide an improved belt vacuum pump. [0004] The technical scheme adopted in the present invention is: [0005] An ...
