Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an on-line monitoring device for the quality of lubricating oil of a chemical compressor. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas and is the heart of a refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving a piston through the operation of an electric motor, and then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] Thus, a refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption) is realized. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. This entry introduces the working principle, classification, accessories, specifications, operating requirements, production of compressors, common faults, as well as environmental protection requirements, selection principles, installation conditions and development trends.

[0004] When the internal mechanical structure of the compressor is operating, lubricating oil is used for lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. When the lubricating oil is used, it is necessary to detect the lubricating oil to determine whether the quality has decreased after long-term use or whether it is mixed with a large amount of impurities, which is not convenient for the compressor to use.

[0005] However, when the existing monitoring sensors are in use, they cannot connect the detection device to the conveying pipeline, so that the sensors need to be installed on the oil storage tank or the equipment, which is likely to cause detection errors due to the sediment at the bottom of the oil storage tank or affect the operation of the equipment. Moreover, for the collected data information, it is directly calculated by the factory computer, which causes a great burden on the factory computer and makes it easy to have deviations and other problems when the computer is performing automatic control.
