Description
Technical Field
The invention relates to a fine filter box and a filter system, in particular to a lubricating oil fine filter box and a filter system for a wind generating set.
Background
The gear box in the wind generating set is an important mechanical component, and the main function of the gear box is to transmit the power generated by the wind wheel under the action of wind power to the generator and enable the generator to obtain corresponding rotating speed, so that the maintenance of the gear box is particularly important in the whole operation and maintenance process of the wind generating set.
Statistics of AGMA from the american gear manufacturing association in 2015 show that about 75% of the failure rates in global industrial equipment are due to poor or incorrect lubrication patterns.
On the one hand, the pollution particles are an important factor causing poor lubrication of the gearbox, so that the gearbox fails, and the pollution particle sources of the existing wind power gearbox are the following four types:
(1) Particles remaining in the apparatus. Mainly refers to pollutants left by abrasion in the initial stage of manufacturing and working, including sand grains which are not thoroughly cleaned, and metal scraps, burrs, welding slag and the like which fall into the sand grains during assembly and repair.
(2) Metal filings of friction pairs in the system. Mainly refers to a product formed by friction and abrasion of surfaces of the friction pair in the relative motion process.
(3) When the system works, particles invaded from the outside are arranged. The air filter mainly comprises impurities such as dust, fine sand and the like, and the impurities enter an oil way system through two ways, wherein the air filter is poor in performance or too coarse in mesh; secondly, when filling or replacing new oil liquid, the used container is not clean or the oil filling port is not provided with a filter device.
(4) Particles resulting from the decay of the oil. During the use process of the oil, friction polymer particles, fiber particles, carbon deposition particles and oil residue particles are generated due to oxidation, vulcanization, nitrification, additive loss and other reasons.
These solid particles, once lodged in the gearbox, will cause more severe wear of the gearbox, in the form of "erosive" wear, "rasping" wear, and "grinding" wear, either alone or in combination; thus, effective removal of contaminating particles is particularly important. The most feasible method for removing the pollution particles is to add a filtering device into a gear box system, and the service life of a bearing of the gear box which can ensure the continuous and effective filtration of lubricating oil can be prolonged by 2.6 times to 3.7 times according to the description of an authoritative mechanism; however, the main filter added to the existing wind power gear box system has an unsatisfactory filtering effect.
On the other hand, most of the current lubricating oil of wind power gear boxes is fully synthetic gear oil, the new oil has a cleanliness approximately in the range of 8-10 according to NAS cleanliness standard of the U.S. aerospace agency, and the range value is suitable for gear oil with viscosity less than 100 # such as No. 46 antiwear hydraulic oil, which can ensure that oil filtration is not blocked under long-term maintenance-free application; however, for higher viscosity gear oils, such as 150, 220, 320 gear oils, this range of values is not effective to ensure that the oil filter is not blocked in long-term maintenance-free applications, and further to ensure continuous lubrication, so as to affect bearing life, and cause failure of the gearbox when severe.
In order to solve the problems, a set of fine filter box can be added outside the main filter box. However, the wind turbine generator system is installed at a high place, and the internal space is extremely narrow, and it is extremely difficult to additionally install a fine filter box. The precise filter box is arranged by the method, so that the operation space for maintenance workers to overhaul and replace the filter element is smaller.
