According to an aspect of the present utility model, the first order of described two-stage filter is 10 micron filters, and the second level is 60 micron filters.10 microns first order filter and 60 microns second level filter make that filtration is more reliable.Even under the situation that bypass is switched on, the on-line filtration unit also can filter lubricant oil, thereby provides temporary protection for lubrication system under the situation that first order filter core lost efficacy.
According on the other hand of the present utility model, be provided with bar magnet in the filter core of described two-stage filter.Bar magnet is conducive to greasy filth, oxide in the filter core adsorpting lubrication oil etc., thereby has improved filter precision.
According to one side more of the present utility model, described cooling unit has a solenoid valve.Solenoid valve can be controlled the bypass of cooler.
According to another aspect of the present utility model, described cooling unit has a bypass one-way valve.The bypass one-way valve is used for when pressure reaches threshold value the cooling unit bypass.
According to another aspect of the present utility model, described gearbox lubrication system also comprises an off-line filter element that is connected separately with described fuel tank unit.The off-line filter element is conducive to the lubricant oil in the fuel tank unit is filtered.
The purpose of this utility model also is to provide a kind of wind turbine, and its cost is lower and reliability is higher.This wind turbine adopts aforesaid gearbox lubrication system.
Hereinafter will be in clear and definite understandable mode, the accompanying drawings preferred embodiment is further specified above-mentioned characteristic of the present utility model, technical characteristics, advantage and implementation thereof.
