Embodiment Construction

[0019] The online cleaning method for lubricating oil of oil-injected compressors of the present invention is to introduce the lubricating oil in the oil-injected compressors into the lubricating oil online cleaning system outside the oil-injected compressors under the working state of the oil-injected compressors. In the process, the liquid impurities brought by the inlet of the compressor are removed by the vacuum removal device;

[0020] At the same time, according to the impurity content of the inlet liquid detected by the inlet liquid impurity detection device, the automatic start and stop of the system is controlled. By detecting the impurity content of the inlet liquid in real time, and transmitting the data to the control device in real time, the control device controls the start and stop of the lubricating oil online cleaning system.

[0021] Alternatively, the automatic start and stop of the system is controlled according to the pressure at the suction end of the com...

Abstract

The invention discloses an on-line cleaning method for oil injection compressor lubricating oil and a system thereof. Under the working state of an oil injection compressor, lubricating oil is introduced into an on-line cleaning system except the compressor; in the system, liquid impurities brought from a compressor inlet are removed from the lubricating oil by a vacuum removal device; meanwhile, the system is controlled to be automatically started and stopped according to the inlet liquid impurity content detected by an inlet liquid impurity detection device or compressor suction end pressure detected by the pressure sensor. Parts of lubricating oil are subjected to circulating cleaning outside the compressor under the working state of the oil injection compressor. On the premise that the normal work of the compressor is not affected, liquid impurities in the lubricating oil are removed, and the quality of the lubricating oil is improved to satisfy the lubrication requirement of the compressor so as to prolong the service life of the lubricating oil and improve the working efficiency of the compressor.

Description

[0001] technical field [0002] The invention relates to an online cleaning method for lubricating oil, in particular to an online cleaning method for lubricating oil of an oil injection compressor. The invention also relates to a system for realizing the online cleaning method of lubricating oil of the oil-injected compressor. Background technique [0003] Since the existing lubricating oil system of the oil-injected compressor cannot realize the online removal of liquid impurities, after a period of operation [0004] Finally, excessive accumulation of liquid impurities will cause the lubricating oil to decompose and deteriorate, which cannot meet the lubrication needs of the compressor and is difficult to restore. Therefore, the lubricating oil of the existing oil-injected compressor adopts the mode of regularly shutting down and discharging new oil. The main disadvantage of this method is that the operation is cumbersome and affects the normal operation of the compr...
