The control method put.
The interactive heat abstractor of wind-power electricity generation reduction gearing fuel tank is divided into 4 kinds of work according to the difference that cutting oil is indexed
Pattern：1. 4. high temperature of the medium/low pressure of 2. high pressure 3. of low temperature
Before start work every time, it is necessary to first start lubrication and the cooling device of electricity generation system, treat that each oil site is fully obtained
Work in starter receiver case to after lubrication.Low-temperature cool starting state is in etc. system, first heater is (by electric hydraulic oil pump 3
Constitute with high-pressure safety valve 4), gear oil is heated into Restarter.
As shown in Fig. 2 heat abstractor working condition 2, under high pressure conditions, (in the embodiment of the present invention, high pressure is device
More than 10bar), during due to just starting shooting, gear oil temperature is relatively low, so the viscosity of gear oil is big, causes pressure rise in device,
Gear oil viscosity greatly cannot be by fine cleaner 5, therefore gear oil is directly consisted of with electric hydraulic oil pump 3 high-pressure safety valve 4
Loop, the circulation of accelerating gear oil, makes oil temperature raise rapidly, reduces the pressure in device.
As shown in figure 3, heat abstractor working condition 3, with the circulation of gear oil, gear oil temperature is constantly raised, pipeline
In pressure be gradually lowered, high-pressure safety valve 4 is automatically switched off, it is middle pressure safety valve 6 automatically open up.Pressure drop in the embodiment of the present invention
During to below 10bar, high-pressure safety valve 4 is closed, and middle pressure safety valve 6 is opened.A gear oil part is through going out oil cut-off valve 2, electricity
Hydrodynamic pressure oil pump 3, middle pressure safety valve 6, coarse filter 7, temperature-sensing valve valve 9, oil return stop valve 10 flow back to gear-box 1 and constitute loop stream
Return gear tank；Another part flows back to gear tank 1 after then flowing through heat exchange water tank 12 again.
After gear oil temperature is further raised, pipeline is in low-pressure state, and middle pressure safety valve 6 is automatically switched off.The present invention
In embodiment, when pressure is less than 3bar, middle pressure safety valve 6 cuts out.Gear oil Jing after fine cleaner and coarse filter double-filtration
Pipeline flows back to gear-box and constitutes loop, if oil temperature now continues to raise, the increase of 3 flow of electric hydraulic oil pump.
After device long-play, gear oil oil temperature is caused to be in the condition of high temperature, then device is cooled down to gear oil, this
In inventive embodiments, oil temperature starts cooling when being more than 70 degree, to guarantee oil temperature not over 70 degree.As shown in figure 4, heat abstractor
Working condition 4, now as temperature exceedes threshold value, temperature-sensing valve 9 cuts out, and after gear oil first passes through two-stage filter filtration, enters
Heat exchange water tank 12, by unnecessary heat transfer to cooling water in heat exchange water tank 12.Cooling water through temperature sensor 13,
Flow sensor 14 gathers cooling water temperature, and flow passes data to control unit 18, by control unit in real time according to flow
Information control electric water pump 15, the rotating speed for controlling electronic cooling fan 17 according to temperature information, cooling water is strong in the radiator 16
System radiating, is finally reached the purpose of fluid cooling, and the oil-out and oil cooling service pipe of the fluid Jing heat exchange water tanks 16 after cooling are returned
Oil cut-off valve 10, returns gear tank 1.
