Hydraulic oil change device of gear casing of wind driven generator set

Abstract

The invention relates to an oil change device, in particular to a hydraulic oil change device of a gear casing of a wind driven generator set, which can be applied to the field of wind energy and can be used in a tower foundation so that lubricating oil of the gear casing of a blower can be replaced. The hydraulic oil change device of the gear casing of the wind driven generator set comprises the gear casing and an oil tank, wherein a gear pump is communicated with the oil tank through a pipeline, the gear pump is driven by a motor and is connected with a fine oil filter through a pipeline, the fine oil filter is connected with an oil exhaust hole of the gear casing through a pipeline, a manual reversing valve is arranged on the pipeline between the gear pump and the fine oil filter, a first branch pipeline is arranged on a pipeline between the manual reversing valve and the fine oil filter, and the end part of the first branch pipeline is provided with an overflow valve. The invention has the advantages of solving the defects caused by maintenance, improving the efficiency and the reliability in the maintenance process, and reducing the cost of the operation and the maintenance of the wind driven generator set.

Description

technical field [0001] The invention relates to an oil change device, in particular to a hydraulic oil change device for a gearbox of a wind power generating set, which is applied in the field of wind energy and can be used to replace the lubricating oil of the gearbox of the wind turbine at the base of the tower. Background technique [0002] The process of replacing the lubricating oil of the gear type of the traditional wind turbine is as follows: manually transport the lubricating oil that needs to be replaced to the interior of the nacelle through the elevator equipped with the tower, and then manually discharge the waste lubricating oil inside the original gear. Finally, the waste lubricating oil is transported back to the base of the tower through an elevator for unified treatment. The disadvantages of the traditional technology are as follows: the heavy lifting of new lubricating oil or the landing of waste lubricating oil makes the labor intensity of workers high, ...

AI Technical Summary

Problems solved by technology

The disadvantages of the traditional technology are as follows: the heavy lifting of new lubricating oil or the landing of waste lubricating oil makes the labor intensity of workers high, and only relying on the gravity of lubricating oil to discharge, the process takes a long time and wastes manpower. The whole oil change process takes 6-8 hours , when draining used lubricating oil and injecting new lubricating oil, the process of draining and injecting will cause splashing or spraying of lubricating oil

Increased cost of the entire repair and maintenance process
