Problems solved by technology

[0006] 1. The once-a-year hydraulic oil quality inspection cannot detect signs of oil deterioration in time
[0007] 2. If the oil quality is found to be poor, it will take a long time to improve the oil quality
For the above two processing methods, for emergency equipment, the outage time is longer, and there are certain hidden safety risks.
[0008] 3. The existing equipment does not have the function of emergency oil replenishment
If external leakage occurs, the oil in the oil tank cannot meet the liquid level required for equipment operation, which will cause the hydraulic hoist system to fail to work in extreme cases

Abstract

The invention relates to a hydraulic oil quality on-line guarantee system for a hydraulic hoist of a hydropower station, which comprises an oil return main pipe, an oil supply main pipe and an accident oil main pipe, the oil return main pipe, the oil supply main pipe and the accident oil main pipe are communicated with an oil tank of the hydraulic hoist through pressure hoses, and the accident oil main pipe is communicated with an accident oil pool. An accident oil pump is connected to a pipeline between the accident oil header pipe and the accident oil pool; the oil return system is communicated with the oil return header pipe and comprises an oil return pump and an oil return tank, and the oil return pump is mounted between the oil return tank and the oil return header pipe; the oil supply system is communicated with the oil supply header pipe and comprises an oil supply pump and an oil purification tank, and the oil supply pump is mounted between the oil purification tank and the oil supply header pipe; and the oil filtering system is connected between the oil return system and the oil supply system. The hydraulic oil of the hydraulic hoist of the hydropower station can be monitored in real time and replaced and filtered in time, and stable and safe operation of the hydropower station is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydropower station operation, in particular to an online guarantee system for the quality of hydraulic oil of a hydraulic hoist of a hydropower station and a control method thereof. Background technique [0002] In the water conservancy system engineering, especially the hydropower station, in order to ensure the safe operation of the power plant equipment, an accident quick gate is set at the water inlet of the water diversion and power generation system. To prevent major accidents such as flooded workshops in the downstream of the waterway, so as to ensure the safe operation of the power plant workshops and equipment. In order to realize the quick closing of the accident quick gate in a short period of time, the hydraulic hoist structure is currently used to control the opening and closing of the accident quick gate, so the safe and stable operation of the accident quick gate is directly related to the ...
