Problems solved by technology

[0003] However, there are two main problems in the oil-lubricated refrigeration system: on the one hand, when the lubricating oil in the compressor enters the refrigeration / heat pump system with the compressor exhaust, it affects the heat transfer performance of the system
On the other hand, when the external system process is complicated, in order to ensure the safe operation of the compressor, the oil return problem of lubricating oil brings great difficulties to the system design

Abstract

The invention relates to the technical field of compressor equipment and discloses a compressor exhaust mechanism and a compressor. The compressor exhaust mechanism comprises an exhaust cavity, a connecting pipe, an oil separating cavity and an oil bath which are sequentially connected, wherein the connecting pipe is connected with the oil separating cavity in the tangent line direction of the oil separating cavity; an exhaust pipe is arranged at the top of the oil separating cavity, an oil discharging opening is arranged in the bottom of the oil separating cavity, and an oil discharging assembly is arranged at the part of the oil discharging opening; and the oil bath communicates with the oil separating cavity through the oil discharging opening. According to the compressor exhaust mechanism provided by the invention, by arranging the oil separating cavity, lubricating oil in exhaust gas is separated under centrifugal action in the running process; when the compressor stops running, the oil discharging assembly is opened by utilizing pressure difference formed by the variation of pressure at the two sides of the oil separating cavity, and the lubricating oil in the oil separating cavity flows back into the oil bath in a compressor housing; and therefore, oil return is realized in the compressor, the oil content of a system is reduced, and the heat exchange efficiency of the system is increased.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a compressor exhaust mechanism and a compressor thereof. Background technique [0002] Lubricating oil is an effective measure to alleviate the friction between the piston and cylinder of the linear compressor, improve the sealing effect of the gap, and improve the refrigeration performance of the linear compressor. [0003] However, there are two main problems in the oil-lubricated refrigeration system: on the one hand, when the lubricating oil in the compressor enters the refrigeration / heat pump system along with the compressor exhaust, it affects the heat transfer performance of the system. On the other hand, when the external system process is complicated, in order to ensure the safe operation of the compressor, the oil return problem of lubricating oil brings great difficulties to the system design. [0004] Therefore, the oil separation and oil return technolo...
