The generation of lubricating system " supercooling " failure, realizes the effect of the fault rate of reduction lubricating system.
Above-mentioned lubricant passage way system and its control method are described in detail below in conjunction with the drawings and specific embodiments.
As shown in fig. 1, a kind of wind turbine generator system gear box lubricating system of the invention, mainly sets in the lubricant passage way of use
Putting part includes：It is oil pump 1, filter 2, heat-exchanger rig 3 (including force fan 3.1 and heat exchanger 3.2), temperature-sensing valve 4, unidirectional
Pressure valve 5, safety valve 6, gear-box oil sump 7, temperature sensor 8, solenoid directional control valve 9.
Oil pump 1 is driven by single-speed motor, for gear oil to be pumped out from oil sump 7, by filter 2 by gear oil
Particulate matter is filtered.Temperature-sensing valve 4 makes gear oil flow through heat exchanger 3.2 when oil temperature is high, forces fan 3.1 to be opened to heat exchanger
Gear oil in 3.2 is cooled down；Temperature-sensing valve 4 makes gear oil be no longer flow through heat exchanger 3.2 when oil temperature is low, swims directly down
Flow back to oil sump 7.Temperature sensor 8 will export oil temperature and feed back to Wind turbines master control system, and master control system reaches in outlet oil temperature
During triggering temperature, manipulate solenoid directional control valve 9 and determine whether gear oil flows through one-way pressure valve 5, then flow back to oil sump 7.Work as system
Occur blocking, when causing pressure to rise too high, gear oil directly via the safety valve 6 of fuel pump outlet, flows back to oil sump.

Mouth oil temperature change, controls the open and close of lubricating system heat exchange function；Heat exchanger 3.2 is monitored using temperature sensor 8
Outlet oil temperature, according to outlet oil temperature change, control solenoid directional control valve 9 open and close, when export oil temperature it is too low when, limitation
The gear oil flow of heat exchange loop, reduces the heat-exchange capacity of heat exchanger 3.2, so as to not use double speed Oil pump electrical machinery
Under the conditions of, it is to avoid the generation of " supercooling " failure.
During practical application, above-mentioned lubricating system of the invention mainly includes three kinds of operating modes：Temperature-sensing valve 4 closes operating mode, temperature-sensing valve 4
Open ＆ one-way pressure valves 5 and close operating mode, and temperature-sensing valve 4 opens ＆ one-way pressure valves 5 and opens operating mode.
Under the conditions of the import oil temperature of heat exchanger 3.2 is less than the opening temperature of temperature-sensing valve 4, lubricating system is closed in temperature-sensing valve 4
Close operating mode.Under the operating mode, a small amount of interior due to temperature-sensing valve 4 is let out, and most gear oils are around (the flow Q of over-heat-exchanger 3.2c),
Flow through bypass circulation (flow Qf), solenoid directional control valve 9 opens (flow Qt2), gear oil mainly flows back to oil by solenoid directional control valve 9
Pond 7, while a small amount of gear oil is by (the flow Q of one-way pressure valve 5t1) flow back to oil sump 7.The flow system flow relation of the operating mode such as formula 1
It is shown.
Qt=Qt1+Qt2≈Qf (1)
In formula 1, QtIt is lubricating system total flow, similarly hereinafter.
Higher than the opening temperature of temperature-sensing valve 4, the outlet oil temperature of heat exchanger 3.2 is higher than master control to the import oil temperature of heat exchanger 3.2
The solenoid directional control valve 9 of system is closed under triggering temperature conditionss, and lubricating system is in temperature-sensing valve 4 and opens the closing work of ＆ one-way pressure valves 5
Condition.Under the operating mode, as the import oil temperature of heat exchanger 3.2 gradually rises, the unlatching amplitude of temperature-sensing valve 4 is incrementally increased, and flows through bypass
Loop is shifting with the gear oil flow of heat exchanger 3.2, until temperature-sensing valve 4 is opened completely, a small amount of tooth let out in temperature-sensing valve 4
Wheel oil flows through bypass circulation, and most gear oils flow through heat exchanger 3.2；Solenoid directional control valve 9 keeps it turned on, gear oil
Oil sump 7 mainly is flowed back to by solenoid directional control valve 9, while a small amount of gear oil flows back to oil sump 7 by one-way pressure valve 5.The operating mode
Flow system flow relation is as shown in formula 2 and formula 3.
Temperature-sensing valve 4 does not open Q completelyt=Qt1+Qt2=Qf+Qc (2)
Temperature-sensing valve 4 opens Q completelyt=Qt1+Qt2≈Qc (3)
, higher than the opening temperature of temperature-sensing valve 4, the outlet oil temperature of heat exchanger 3.2 is less than master control system for the import oil temperature of exchanger 3.2
The solenoid directional control valve 9 of system is closed under triggering temperature conditionss, and lubricating system is in temperature-sensing valve 4 and opens the unlatching work of ＆ one-way pressure valves 5
Condition.Under the operating mode, the import oil temperature of heat exchanger 3.2 is maintained at more than the opening temperature of temperature-sensing valve 4, and temperature-sensing valve 4 keeps it turned on shape
State, gear oil flows separately through bypass circulation and heat exchanger 3.2；Because the entering air temperature of heat exchanger 3.2 declines, make hot friendship
The outlet oil temperature of parallel operation 3.2 constantly declines, and the outlet oil temperature of heat exchanger 3.2 closes temperature less than the solenoid directional control valve 9 of master control system
When spending, solenoid directional control valve 9 is closed, and most gear oils flow back to oil sump 7 by one-way pressure valve 5, while very small amount gear oil
Due to being let out in solenoid directional control valve 9 oil sump 7 is flowed back to by solenoid directional control valve 9.The flow system flow relation of the operating mode such as formula 4 and formula 5
It is shown.
Temperature-sensing valve 4 does not open Q completelyt=Qf+Qc≈Qt1 (4)
Temperature-sensing valve 4 opens Q completelyt≈Qt1≈Qc (5)
It is a feature of the present invention that using reliability one-way pressure valve and solenoid directional control valve higher, realizing " supercooling " failure
When trend occurs, gear oil is imported all the way by one-way pressure valve by solenoid directional control valve, function is hindered using the liquid of one-way pressure valve,
Reduction flows through the gear oil flow of heat exchanger, it can be seen from equation of heat balance, the heat exchange energy of heat exchanger in lubricating system
Power (being embodied by the coefficient of heat transfer) will be reduced with flow reduction, so as to evade the risk of " supercooling " failure generation.Heat exchange
The coefficient of heat transfer of device is as shown in Figure 2 with the relation curve of flow.
The triggering temperature of solenoid directional control valve 9 is T0, the opening temperature of temperature-sensing valve 4 is TS, generally T0<TS.Temperature is passed
The monitoring outlet oil temperature of heat exchanger 3.2 of sensor 8, master control system is fed back to by signal, and master control system is according to outlet oil temperature and T0's
Relativity makes decisions --- it is turned on and off solenoid directional control valve 9.
It is assumed that when the entering air temperature of heat exchanger 3.2 is less than 10 DEG C, the gear oil flow of heat exchanger 3.2 is not less than
100L/min can meet gear-box cooling requirements, then adjust the spring pressure of one-way pressure valve 5, make by one-way pressure valve 5
Gear oil flow be no less than 100L/min, so as to ensure that gear-box radiating is good, while ensuring that flowing through heat exchanger 3.2 exports
Gear oil temperature be unlikely to too low, cause the blocking of heat exchanger 3.2.
The above, is only presently preferred embodiments of the present invention, and any formal limitation is not made to the present invention, this
Art personnel make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all fall within this hair
In bright protection domain.
