Background
According to the scheme, the pump body and the baffle plate are integrally designed, so that the size of an inner hole of the baffle plate limits the size of an eccentric circle of a crankshaft, and the displacement of the pump body is limited; and the relative movement speed between the baffle plate and the roller is very high, so that the end face abrasion is extremely easy to form. Based on the above design needs, innovative structural designs are needed.

In summary, the pump body diaphragm inner diameter D limits the displacement margin increase.
In order to meet the market demands, the contradiction relation between the inner diameter D and the displacement V of the pump body partition plate needs to be solved.

In order to meet the assembly with the eccentric part of the crankshaft, the inner hole of the partition plate of the compressor in the prior art is designed to be larger, but the eccentric amount of the crankshaft cannot be larger, so that the maximum displacement of the pump body of the compressor cannot be improved, and meanwhile, the technical problems that the sealing distance of the partition plate is smaller, the due sealing effect of the compressor cannot be guaranteed and the like are solved.
