An automatic quantitative grease injection device for wind turbines

Abstract

The invention discloses an automatic quantitative grease injection device for a wind turbine generator. The automatic quantitative grease injection device comprises an automatic quantitative grease injection display control system, a platform scale, a part needing grease injection, an air compressor and a pneumatic grease injection pump. A grease storage bucket is arranged on the platform scale, the upper end of the grease storage bucket is provided with the pneumatic grease injection pump, one end of the platform scale is provided with a supporting column, and the upper end of the supporting column is provided with the automatic quantitative grease injection display control system. The automatic quantitative grease injection display control system comprises a main control panel, a 7-inch HMI display module, a pressure sensor module, a weight sensor module, a power module, a pneumatic grease injection pump control module, a data storage module, an input module and a sound-light alarm module. The automatic quantitative grease injection device has a self fault diagnosis ability, is capable of precisely controlling the grease injection quantity, free of specially-assigned person guard, higher in efficiency compared with manual grease injection, capable of generating a grease injection record and capable of displaying the grease injection schedule in real time, and has the break point grease injection and sound-light alarm functions.

Description

technical field [0001] The invention relates to the technical field of grease injection for wind turbines, in particular to an automatic quantitative grease injection device for wind turbines. Background technique [0002] At present, most manufacturers use fixed-displacement pneumatic grease injection pumps for grease injection, and the grease injection volume is controlled by the grease injection time. The defect of this method is that the displacement of the pneumatic grease injection pump is greatly affected by the outside world, such as the viscosity Or the internal resistance of the parts increases, which directly affects the amount of grease injected into the parts, reducing the amount of grease injected; some manufacturers use fixed-displacement pneumatic grease injection pumps to control the amount of grease injected by manual tracking and weighing , the defect that this method exists is that the greasing process needs personnel to be on duty, increases the labor lo...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the grease injection process basically does not require personnel to be on duty, but there is a lack of grease injection records, which cannot be traced back, personnel will make mistakes when adding or subtracting weight, the amount of grease injection cannot be guaranteed when the platform scale fails, and there is no sound and light alarm function.
