The invention discloses a fan hydraulic oil filter which comprises a filter tank body, an air release valve is arranged on the top of the filter tank body, a pressure gauge is arranged on the side portion of the air release valve, a liquid inlet pipe and a liquid outlet pipe are arranged on the upper portion of the filter tank body, and a liquid outlet is formed in the lower portion of the filter tank body. The liquid inlet pipe and the liquid outlet pipe are both communicated with the interior of the filtering tank body. The filter screen can be fixed by arranging the upper retaining seat and the lower retaining seat in the filter tank body, meanwhile, the liquid outlet is formed in the lower part of the filter tank body for discharging liquid, and when the filter screen is replaced, only the valve connected with the liquid inlet and the liquid outlet needs to be closed, and the liquid outlet in the bottom of the filter tank body is opened, so that the filter screen can be replaced. The lower part is opened, the filter element for filtering is taken out, and meanwhile, a new filter element is mounted, so that the oil filter is convenient and quick to use, the replacement time is greatly saved, the use of the fan is not influenced, and the oil filter is convenient and quick.
Description
technical field [0001] The invention relates to the technical field of fan hydraulic oil cleaning, in particular to a fan hydraulic oil filter. Background technique [0002] The wind turbine gearbox is installed in the wind turbine generator cabin, and its function is to transmit the blades driven by the wind to the generator for power generation after speeding up through the gearbox. The lubrication of the gearbox is a forced lubrication system, which is equipped with an oil pump, a filter, a cooler, etc. After the oil pump sucks oil from the oil suction port of the lower box of the gearbox, the lubricating oil is filtered by the filter, and then cooled by the cooler and sent to the oil through the pipeline. To lubricate the bearings, gears and other parts of the gearbox. The filter used in the gearbox lubrication system of the wind turbine is usually composed of a shell, a fine filter element, a coarse filter element and a bypass valve. When the system is cold started (lu...
