Abstract

The invention relates to the technical field of power equipment, and discloses a convenient-to-use oil change device for a hydraulic control system of a wind turbine generator, which comprises a machine body, a mounting plate is arranged in the machine body, an oil storage barrel is fixedly mounted on the mounting plate, and a left port of the oil storage barrel is connected with a first delivery pump; a first one-way valve is connected to a left end opening of the first conveying pump and fixedly installed on the front face of the machine body. When the hydraulic control system is subjected to oil change, a second one-way valve is in butt joint with an oil discharge outlet of the control system, waste oil in the hydraulic system is conveyed into a waste oil barrel through a second conveying pump, the second one-way valve is separated from an oil port after completion, and a first one-way valve is in butt joint with an oil injection port of the hydraulic system; new oil is injected into the hydraulic system through the first conveying pump, the structure is simple, the number of auxiliary tools is small, integration of the oil changing device, the oil storage barrel and the waste oil barrel is achieved, and the safety of high-altitude operation is improved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an oil changer for a hydraulic control system of a wind turbine that is easy to use. Background technique [0002] With the rapid development and wide application of wind power generation technology, the scale of wind farms is getting larger and larger, and the number of wind turbines is increasing. It is becoming more and more important to ensure the normal and stable operation of wind turbines to the maximum extent. At this stage, wind turbines using hydraulic control systems have been widely used. As one of the important components of wind turbines, they must be used and maintained correctly. In order to ensure the stable and reliable operation of the hydraulic control system, we must attach great importance to the hydraulic oil quality of the hydraulic control system. The performance of hydraulic oil will gradually decay with the increase of use time until it...
