Abstract

The invention discloses a pump station oil leakage prevention and control method and system of a hydraulic system and a lubrication system. The method comprises the following steps that firstly, a low liquid level limiting value and an ultralow liquid level limiting value of an oil tank of a pump station are set; secondly, the peak value speed Vmax of decrease of the liquid level of the oil tank when the pump station operates normally and needs the maximum oil use amount is calibrated; thirdly, liquid level information is collected in real time through a liquidometer and sent to a master control system; fourthly, the master control system calculates the real-time decrease speed V of the liquid level of the oil tank according to the liquid level information collected in real time; fifthly, the master control system analyzes and judges the liquid level of the oil tank and sends an alarm warning and a pump stop control instruction. The pump station oil leakage prevention and control method and system of the hydraulic system and the lubrication system prevent the phenomenon of mass oil leakage, implement necessary pump stop control when the oil liquid level continuously descends, lower economic loss and environment pollution caused by oil leakage to the maximum extent, protect safety of a mainframe and prevent damage caused by sudden machine stop in the operating process.

Description

technical field [0001] The invention relates to the technical field of oil liquid level control of hydraulic system pump stations and lubricating system pump stations, in particular to an oil leakage prevention and control method and system for pump stations of hydraulic systems and lubricating systems. Background technique [0002] At present, the liquid level gauge used in hydraulic system and lubrication system pumping station liquid level monitoring includes two signal output forms of analog quantity and limit switch quantity, and one of them can be used, or both can be used to participate in actual control. In terms of liquid level control logic, there are 4 limit points of extremely low liquid level, low liquid level, high liquid level and super high liquid level within the height range of the effective working liquid level from the bottom of the oil tank to the top of the oil tank, which are used to force the oil pump station Stop the pump, alarm, normal and other liq...
