Cooling and dedusting method of gearbox lubricating and cooling system

Abstract

A cooling and dedusting method of a gearbox lubricating and cooling system comprises the following steps that S1, the gearbox lubricating and cooling system is assembled; S2, the speed of an oil pump motor is regulated in the starting or running process; S3, dust and oil films bonded on a cooler and a cooler fan are removed. According to temperature information fed back by mounting in an oil tank of a gearbox, PID automatic control is carried out over the running frequency of the oil pump motor and a fan motor so that a frequency converter can control the running speed of the fan and the running torque of the oil pump motor. In the starting and running process of the oil pump motor, the oil pump motor is made to be started smoothly according to the temperature and viscosity condition of lubricating oil, and the aim of saving energy under the working condition of high temperature is achieved.

Description

technical field

[0001] The invention relates to a cooling and dust removal method, in particular to a cooling and dust removal method for the lubrication and cooling system of a gearbox in a wind turbine. Background technique

[0002] In the field of wind power, the existing gearbox lubrication and cooling systems mostly use fixed-speed cooler fans to cool down the cooler, and cannot adapt the wind speed to the temperature of different environments; these cooler systems also mostly use fixed high power oil pump motor, the torque of the oil pump motor of this cooling system is fixed, the oil pump motor with the same and fixed torque is used in low temperature and high temperature conditions, if the oil pump motor torque is large, the oil pump can be started under low temperature conditions, After the motor starts, the actual required torque is smaller than that at the start. Since the torque is fixed, the oil pump motor will still use this torque when it is running, which wil...
