Abstract

The invention provides a pump body structure and a compressor provided with the same. The pump body structure comprises a cylinder body, a crankshaft and a roller. The cylinder body is provided with an air suction hole and air supplement holes. The crankshaft is provided with an eccentric portion, and the eccentric portion is arranged in the cylinder body. The roller is arranged on the cylinder body in a sleeving manner and located inside the cylinder body. In a compression cycle, the area swept by the inner circle of the roller is S. The air supplement holes are formed in one sides of the endfaces of one or more ends. The area of the cross section of each air supplement hole is B, wherein the intersection of S and B is not equal to phi. Part or whole of each air supplement hole is arranged within the projection area, relative to the cylinder body, of the area swept by the inner circle of the roller, and thus, the arrangement space of the air supplement holes is increased; the effective air supplement area of the air supplement holes is increase; and air supplement is achieved in time when the air pressure of the cylinder body is insufficient, so that the air supplement amount ofthe 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 ...
