Description
Technical field
The invention belongs to wind-powered electricity generation lubricating system technical fields, and in particular to a kind of to reduce the high control of wind turbine gearbox oil temperature
Device processed.
Background technology
Large-scale Wind Turbines wind-powered electricity generation lubricating system mostly uses HYDAC, quite you（PALL）, the lube systems such as the quick Thailand in Shanghai
System, there are wretched insufficiencies for these systems, these systems are using temperature control mode control oil circuit heat dissipation, and thermostat valve often occurs in use
It is not closed completely and is opened unsmooth phenomenon, causes lubricant medium that can not all participate in heat dissipation and hypertonia phenomenon.
For the deficiency of temperature control mode, at present some systems mainly using pressure control by the way of, i.e., when wind turbine is low
When startup temperature, the viscosity of medium is larger, causes the pressure of system higher, and check valve opens draining, can avoid high pressure oil impact and dissipates
Hot device, but most of system or device for using this mode, parts of lubricating oil directly flow back to gear-box after shunting
The lubricating oil of bottom, this part will be no longer pass through the oil dispenser of upper gear case, so that always being flowed for lubricating system
Amount is lost, and the requirement of lubrication flow is not achieved.
Control valve plate is Al-alloy parts at present, since check valve can be opened repeatedly, it will the contact at sealing is seriously worn
Area, and contacted firmly with control valve plate, service life is short, easily reveals.
The quality of lubricating oil product drastically influences the ability of its lubrication, the final operation for influencing equipment, still, at present existing
During the use of field, there is no the devices of setting real time monitoring oil quality.

Specific implementation mode
Below in conjunction with attached drawing and specific embodiment, the present invention is further illustrated.
As shown in Figure 1, the control device of wind turbine gearbox oil temperature can be reduced.Motor 1 drives gear pump 2 to supply lubricating oil,
Pressure tap 3 and safety valve 4 are provided on lubricant passage way, pressure tap 3 is connected with pressure measuring unit, and lubricant passage way is connected to filter
6, lubricating oil is divided into two-way after the filtering of filter 6：Upper gear case is connected to by fittings body III 11 after control valve 7 all the way
Oil dispenser 13, another way is connected to air cooling equipment 10 through fittings body II 9, oil dispenser is connected to using fittings body III 11
13。
Filter 6 is formed by connecting by coarse filtration, refined filtration, check valve, pollution transmitter, pressure measuring tie-in and fuel outlet ball valve.It is air-cooled
Device 10 is formed by connecting by motor, fan blade, radiator and by-passing valve.
The process of its work is：Motor 1 drives 2 fuel feeding of gear pump, and when system pressure is less than 10bar, safety valve 4 is in
Closed state, lubricating oil flow to filter 6, and since system just starts, lubricating oil viscosity is big at this time, and system pressure is made to increase,
Lubricating oil is after the 4bar check valves of filter at this time, using 50 μm of progress coarse filtration.With being incremented by for system operation time,
System pressure continuously decreases, and when less than 4bar, then passes through 10 μm of refined filtrations.When system pressure is higher than the unlatching pressure of control valve 7
When power, control valve 7 is then in open state, after lubricating oil flows through fittings body III 11, then flows into oil dispenser 13, is filled to gear-box
It shares in the benefit cunning, such connection type is compared to previous design, i.e. the part when lubricating oil pressure is higher than the Opening pressure of control valve 7
Lubricating oil directly flows back to inside grease-box（The flow that this part is laid down at this time is no longer by oil dispenser 13 to gear-box
Oil site is lubricated, and system total flow is lost）, can guarantee that system total flow is constant.When system pressure is less than control valve 7
Opening pressure when（Wind turbine normal operating condition or the cabin condition of high temperature）, lubricating oil passes through fittings body II 9, to lubricating oil progress
It is cooling（All media are radiated by radiator）, gear-box is returned after then flowing through fittings body III 11.
Control valve 7 is connected by control valve plate 15 with check valve.Control valve plate 15 and original control valve plate installation dimension
Identical, for valve plate 15 with check valve using cone seal form, junction keeps sharp edge, facing-up.Check valve is plug-in structure,
Check valve oil inlet is identical as 10 oil inlet of air cooling equipment, and oil outlet is connected to the oil dispenser 13 of upper gear case, check valve
Pressure is set as 8-10bar.The effect of plug screw 16 is holddown spring and tapered sleeve.Plug screw sealing ring 17 ensures that medium does not leak.Due to
Control valve plate is Al-alloy parts, and in opening process, contact position is seriously worn repeatedly in check valve, by increasing tapered sleeve 18（Through overheat
After processing）The service life of control valve plate can effectively be extended, while playing the role of guiding.Working spring 20 ensures spool 19
Open and close.Inner elements of check valve 19 at work can be along the front and back sliding of tapered sleeve 18, to open and close check valve.With filter
Sealing ring 22 when being connected ensures that joint surface is not revealed.Coupling 14 is arranged at one-way valved outlet, can connect greasy dirt sensing
Device monitors oil quality in real time at the scene during use.Tapered sleeve sealing ring 21 can prevent medium from leaking.
The present invention uses tapered check valve control mode, passes through pressure controling mode open check valve.Control valve group simultaneously
In tapered check valve side open coupling 14, for connecting greasy dirt sensor, can monitor in real time oil quality variation feelings
Condition.
Dielectric viscosity is big when winter wind turbine cold-starting, and system pressure is high, and check valve opens emptying, and high pressure oil is avoided to impact
Radiator, while the oil mass of unloading that check valve is opened flows completely through distributor 13 in lubricating system, ensures lubricant medium total flow
It is constant.When medium temperature is got higher along with the run time of wind turbine, system pressure reduces, closed check valve, ensures all
Medium passes through radiator heat-dissipation.This inventive control device, which avoids former thermostat valve, to be influenced by oil product precision and is failed, to
Cause to be not closed completely when medium high temperature, when low temperature does not open phenomenon, and whole medium participates in heat dissipation when solving high temperature；It is flowed when low temperature
It measures after shunting without radiator, avoids radiator high pressure from bursting and leak, while meeting the system total flow for being used to lubricate not
Become.
