Compressor lubricating system performance detection and fault early warning method

Abstract

The invention provides a compressor lubricating system performance detection and fault early warning method. A non-contact measurement mode is adopted for a flow, a temperature and the like, so that pollution to a detected fluid is avoided, and performance detection and analysis can be completed without damaging a pipeline of a lubricating system; on-line testing and analysis of an actual displacement of an oil pump, a heat exchange coefficient and the cooling efficiency of an oil cooler, the filtering precision of an oil filter, the quality of oil and the like can be realized, and an on-line monitoring and fault diagnosis and positioning method of a compressor lubricating system is formed; by regularly monitoring the performance of the lubricating system, the service life of each part and the oil replacement period can be analyzed and predicted, and fault early warning of the lubricating system is achieved; and the test is simple and convenient, and the test can be completed without stopping the compressor in the performance detection process of the lubricating system.

Description

technical field [0001] The invention relates to the field of compressor lubricating systems, in particular to a method for performance detection and failure warning of the compressor lubricating system. Background technique [0002] The natural gas compressor lubrication system is a key link to ensure the normal operation of the compressor. It can effectively reduce the wear of the friction pair and reduce the working temperature of the parts. In actual use, the natural gas compressor lubrication system only depends on the two parameters of its oil temperature and oil pressure to judge whether the lubrication system is working normally. However, whether the actual flow rate of the oil pump outlet in the lubrication system reaches its rated flow rate, whether the heat transfer efficiency of the oil cooler, and whether the quality of the lubricating oil meets the requirements are basically not tested. Only relying on experience to replace the lubricating oil within the specifi...

Problems solved by technology

[0003] The main purpose of the present invention is to provide a method for performance detection and fault warning of the compressor lubrication system, which solves the problem that the performance of each component in the compressor lubrication system cannot be directly and effectively detected, and can only be carried out when the lubrication pipeline is damaged and the machine is shut down. Detection one by one, low detection efficiency, time-consuming and labor-intensive problems
