Embodiment 1

[0031] Such as figure 1 As shown, the on-line electrostatic oil filter device and method for the wind turbine gearbox described in the patent of the present invention includes the control box 4 and the distribution box 5 which are electrically connected in sequence; and also includes the oil inlet 0 and the inlet Valve 1, oil pump 2, electrostatic filter 3, intermediate valve 6, tail end filter 7, outlet valve 8 and oil outlet 9; inlet pressure sensor 21 is installed in the oil circuit between inlet valve 1 and oil pump 2; An outlet pressure sensor 81 is installed in the oil passage between the filter 7 and the outlet valve 8 .

[0032] The on-line electrostatic oil filter device and method for the wind power generator gearbox described in the patent of the present invention, in this embodiment, the electrostatic filter 3 is set as a box body, consisting of an upper end cover 314 of the electrostatic filter, a body 315 of the electrostatic filter, The electrostatic filter is ...

Embodiment 2

[0047] As shown in 2, the first installation method of the wind turbine gearbox online electrostatic oil filter device in the patent of the present invention, the wind turbine gearbox online electrostatic oil filter device A2 is connected in series with the wind turbine gearbox radiator A3 oil circuit. The gearbox lubricating oil containing impurities flows out from the wind turbine gearbox A1, first enters the wind turbine gearbox online electrostatic oil filter device A2 to filter, then enters the wind turbine gearbox radiator A3 to cool down, and then returns to the wind turbine gear box A1.

Embodiment 3

[0049] On the basis of Example 1, as image 3 The installation method 2 of the online electrostatic oil filter device of the wind turbine gearbox described in the patent of the present invention is shown. The oil circuit of the online electrostatic oil filter device A2 of the wind turbine gearbox and the radiator A3 of the wind turbine gearbox are independent of each other. The gearbox lubricating oil containing impurities flows out from the wind turbine gearbox A1, enters the wind turbine gearbox online electrostatic oil filter device A2 to filter, and then returns to the wind turbine gearbox A1. The hot gearbox lubricating oil flows out from the wind turbine gearbox A1, enters the wind turbine gearbox radiator A3 to cool down, and then returns to the wind turbine gearbox A1.

[0050] It takes a certain amount of time for the charged impurities to be captured by the dust collector, and the flow rate of the radiator cannot be too low under high power. When the first installat...

Abstract

The invention discloses an online static oil filter device and method for a wind power generator gear case, and belongs to the field of wind power generation. A power distribution box and a control box are included and sequentially electrically connected. An oil inlet, an inlet valve, an oil pump, a static filter, a middle valve, a tail end filter, an outlet valve and an oil outlet are further included and are sequentially arranged along an oil path. The control box is connected with the static filter. Through the static oil filter method, oil mud, oxide, metal particles and other impurities which cannot be filtered through an existing online wind power gear case filter method due to the too small size originally are filtered out, the surface area of a consumable dust collecting body is large, and the service life is relatively long; and meanwhile, the energy consumption of the device is low, and the important significance is achieved for prolonging the service life of the wind power generator set gear case, improving the intelligent degree of a wind power generator set and increasing the utilization hours of the wind power generator set.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to an online electrostatic oil filtering device and method for a gear box of a wind power generator. Background technique [0002] In the field of wind power generation, the gearbox is the core of the wind turbine, and the quality of the lubricating oil during operation directly affects the life of the gearbox. When the gearbox oil life is over and the oil is changed, the contamination of the new oil by impurities in the old oil cannot be ignored. [0003] The traditional online oil filtration of wind turbine gearbox relies on the filtering effect of the filter element, which cannot effectively filter oil sludge, oxides and too small metal debris, and has limited oil purification capacity. The online electrostatic oil filtration method can improve the filtration accuracy and help to prolong the life of the gearbox. Due to the large surface area of ​​the dust collect...
