Abstract

The invention provides a pump body structure and a compressor having the same. The pump body structure includes a cylinder body, a crankshaft and a roller. The cylinder body has an air suction hole and an air supply hole. The crankshaft has an eccentric part, and the eccentric part is arranged in the cylinder body. , the roller is sleeved on the eccentric part and located in the cylinder. During a compression cycle, the area swept by the inner circle of the roller is S, and the air supply hole is located on at least one side of the roller. On one side of the end face of the end, the cross-sectional area of ​​the air supply hole is B, wherein at least part of the air supply hole is arranged in the area swept by the inner circle of the roller within the projection of the cylinder, so that the air supply hole is enlarged The installation space increases the effective air supply area of ​​the air supply hole, and when the cylinder air pressure is insufficient, air is replenished in time, so that the air supply amount of the compressor is sufficient.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a pump body structure and a compressor having the same. Background technique [0002] In the prior art, when the compressor is used for low-temperature heating, due to the low evaporation temperature of the refrigerant, the suction density is small, resulting in serious attenuation of the heating capacity of the compressor at low temperature. There are single-stage air-supplement technology and double-stage air-supplement technology; the two-stage air-supplement technology is also called double-stage enthalpy-increasing compressor, which has good air-supplement effect, but high cost and poor manufacturability. In particular, the displacement of the two cylinders of the two-stage compression is only counted as the displacement of the one-stage cylinder, which leads to the limitation of the displacement of the compressor, which seriously limits the range of use of the ...
