Pump body assembly and compressor

Abstract

The invention provides a pump body assembly and a compressor. The pump body assembly comprises a pump body structure and an oil absorbing structure; the pump body structure comprises a compressing assembly suitable for compressing fluid and a crankshaft connected with the compressing assembly; the end, connected with the compressing assembly, of the crankshaft is an oil inflow end; the end face ofthe oil inflow end extends into the crankshaft to be provided with an oil inflow hole; the oil absorbing structure is arranged on the pump body structure, and comprises an oil absorbing body formingan oil absorbing cavity; one end of the oil absorbing cavity communicates with the oil inflow hole, and the other end extends in the direction away from the oil inflow hole; and the cross section areaof at least one position of the oil absorbing cavity is larger than that of the oil inflow hole. Due to the pump body assembly, when the pump body assembly performs oil pumping, oil firstly enters the oil absorbing cavity and passes through the position, with the cross section area larger than that of the oil inflow hole, of the oil absorbing cavity, disturbance generated during oil pumping can be relieved, vertexes formed nearby the oil inflow end are reduced, and a good oil pumping effect is achieved.

Description

technical field [0001] The invention relates to the technical field of compression, in particular to a pump body assembly and a compressor. Background technique [0002] Compressor is a driven fluid machine that upgrades low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure gas to the exhaust pipe. The refrigerant gas that powers the refrigeration cycle. In order to ensure the normal operation of the compressor and not easily damaged, it is necessary to lubricate the parts of the compressor. [0003] When the compressor is running, the pump oil is lubricated for the compressor. Among them, the pump oil means that when the compressor is running, the central hole of the crankshaft has suction, which brings the lubricating oil to the parts of the pump body and lubricates the parts. When the oi...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the compressor in the prior art is easy to form a vortex between the oil suction hole on the crankshaft and the compressor housing when pumping oil, which affects the oil pumping effect, thereby providing an oil pump that is not easy The pump body components and compressors that generate vortex between the oil suction hole and the casing and have better oil pumping effect
