Abstract

The invention relates to a lubricating oil filter system of a wind power gear box. The filter system is provided with an oil inlet and an oil outlet in butt joint with a gear box, a main pipe connected between the oil inlet and the oil outlet, a circulating pump arranged on the main pipe, and a filter mechanism arranged on the main pipe; the filter mechanism comprises a mechanical filter with a multistage filter screen, and a charging unit for separation of the lubricating oil and positive and negative charging of particles in two parts of the lubricating oil after separation; and the chargingunit is positioned at the upstream of the mechanical filter, and communicates with the mechanical filter through a gathering pipe. The lubricating oil filter system of the wind power gear box greatlyincreases the purifying rate of fine particles of submicron order and below 5 microns, solves online filter problems of high viscosity, high pressure and high flow, is lower on requirement of the water content in the oil, and is compact and reasonable in structural design, low in production cost and lower in maintenance cost.

Description

technical field [0001] The invention relates to a lubricating oil filtering system of a wind power gearbox. Background technique [0002] The rotating machinery of modern equipment, such as generator sets, gearboxes, transmission bearings, etc., are the core power and key equipment in the entire equipment, and their operating status will play a decisive role in the entire set of process equipment. The corresponding lubrication between these transmission parts also ensures the continuous and stable operation of the entire equipment. [0003] The main pollution forms of the lubrication system of large rotating machinery are solid particle pollution, water pollution and aging and deterioration pollution. As far as the current development level of lubrication system pollution control technology is concerned, ordinary solid particle pollution and water pollution can be effectively controlled by means of purification, but the research on ultrafine particle pollution and aging det...
