Problems solved by technology

[0005] The invention provides an oil separator for a compression refrigeration system, the purpose of which is to solve the oil level instability caused by the exhaust pulse of the existing oil separator, which leads to inaccurate monitoring of the lubrication state of the compressor during operation, and even easily causes errors. Alarm or lack of oil damage to the compressor

Abstract

An oil separator for a compression refrigeration system comprises an oil separation shell, a filter screen and an oil level monitoring device, and is characterized in that an exhaust pulse partition plate is arranged in an oil storage area in the oil separator and isolates the area, close to an acting part of the oil level monitoring device, of the oil storage area to form an oil level monitoring area; the bottom of the oil level monitoring area is communicated with the bottom of the oil storage area, the top of the oil level monitoring area is communicated with the upper portion of the working space, and the oil level monitoring device faces the oil level monitoring area. Relative isolation measures are adopted in the monitored area, the isolation can greatly reduce the influence of up-down fluctuation of the oil level of the oil storage area caused by exhaust pulse on the oil level monitoring area, and the communication can correctly reflect the real and stable oil level of the oil storage area. According to the scheme, the problem that the oil level fluctuates up and down due to exhaust pulses can be solved in a small filtering and oil storage space, and the oil sight glass or / and the oil level switch can monitor the correct and stable oil level.

Description

technical field [0001] The invention relates to an oil separation device, in particular to an oil separator used in a compression refrigeration system. The oil separator can make the oil level monitored by the sight glass or oil level switch a correct and stable oil level, so as to accurately obtain the actual amount of lubricating oil currently carried by the refrigeration medium in the compression refrigeration system. Background technique [0002] In the compression refrigeration system, the lubricating oil carried by the refrigeration medium in the working cycle not only plays a lubricating role for the compressor, but also plays a cooling role. The oil separator is an indispensable auxiliary device in the compression refrigeration system. It is usually installed between the compressor discharge port of the compression refrigeration unit and the condenser. It is used to separate the lubricating oil in the high-pressure gas discharged from the compressor without excessive...
