Wind power generation gearbox lubricating and cooling system performance experiment platform and test method

Abstract

The invention discloses a wind power generation gearbox lubricating and cooling system performance experiment platform. The experiment platform comprises an oil tank, a heater group, a to-be-tested lubricating and cooling system, a temperature sensor, a pressure sensor, a flow sensor, an electrical control cabinet and a recirculating air device; the to-be-tested lubricating and cooling system andthe heater group form an open type circulating system; a test method comprises the following steps: heating through the heater group, and simulating heat dissipation of a gearbox in a wind power generation system; measuring flow of the system through the flow sensor mounted on an oil outlet branch; mounting the temperature sensor at an oil inlet, an oil outlet and an air intake of an air cooler, and measuring temperature of the oil inlet, the oil outlet and the air intake of the air cooler; arranging the recirculating air devices side by side at the front of an oil liquid circulating system, thereby providing the air of constant temperature for the air cooler; collecting and recording various data by a data acquisition system. With the experiment platform and the test method provided by the invention, a problem of heat dissipation performance verification of the existing gearbox lubricating and cooling device, and product performance reliability is improved at the same time.

Description

technical field [0001] The invention relates to a performance experiment platform and a test method for a lubrication cooling system of a wind power generation gearbox. Background technique [0002] The most important part of the wind turbine - the nacelle, which contains main components such as gearboxes, generators, and control frequency converters. Since the nacelle is erected on a tower tens of meters high, it is difficult to maintain it. Therefore, All components in the engine room are required to be stable and reliable. [0003] During the operation of the gearbox, there will inevitably be a certain power loss, and the lost power will be converted into heat, which will increase the oil temperature of the gearbox. If the oil temperature rises too high, the performance of the lubricating oil will change, the viscosity will decrease, the aging and deterioration will be accelerated, and the oil change interval will be shortened. Under the action of load pressure, if the ...
