Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of oil equipment self-circulation lubricating cooling system, including oil supply subsystem 1, cooling subsystem 2,
Lubrication subsystem 3, self-loopa subsystem 4, the oil supply subsystem 1, cooling subsystem 2, lubrication subsystem 3 form lubricating oil and follow
Loop back path, the self-loopa subsystem 4 are connect with cooling subsystem 2, and the self-loopa subsystem 4 includes cooling water tank 5, heating
Water tank 6, water pump 7, the cooling water tank 5, heating water tank 6 are in parallel with the water inlet of water pump 7, and pass through water pump 7 and cooling subsystem
2 connection of system, forms water route circuit.
This system is divided into low temperature (less than 25 DEG C) and high temperature (being greater than 40 DEG C) two kinds of operating conditions of starting, (is less than under worst cold case
25 DEG C), since lubricating oil viscosity is larger, the load of oil pump 15 is big, and the starting of oil pump 15 needs that the slow-speed of revolution is kept to run, at this point, opening
Low-temperature signal is fed back to control centre by the variable-frequency motor on dynamic oil pump 15, temperature sensor, and control centre controls variable-frequency motor
Low-power output is kept, thermostat valve 12 adjusts the flow of two sides oil outlet, and oil liquid is made to pass through oil-water- to-water heat exchanger 10, and oil liquid is logical
When crossing oil-water- to-water heat exchanger 10, the heater 21 in heating water tank 6 works, the water in heating water tank, and is sent by water pump 7 to oil-
In water- to-water heat exchanger 10, persistently oil liquid is heated, until oil liquid temperature is between 25 DEG C~40 DEG C.Oil pump 15 is defeated at this time
Power is gradually increased out, and thermostat valve 12 adjusts the flow of two sides oil outlet according to oil liquid temperature, is gradually decreased oil liquid and is flowed through oil-
The flow of water- to-water heat exchanger 10, until the oil liquid flow in oil-water- to-water heat exchanger 10 is zero, oil liquid passes through direct after thermostat valve 12 at this time
Oil site 9 is flowed to, and the heater 21 in heating water tank 6 stops working, water pump 7 also stops working, and oil liquid, which relies on, to be flowed over
Phase mutual friction and the running heat of equipment in journey keep oil temperature.
Under worst hot case (be greater than 40 DEG C), since lubricating oil viscosity is smaller, oil pump 15 loads small, and oil pump 15 can be kept just
Normal revolving speed starting operation.At this point, the variable-frequency motor on starting oil pump 15, temperature sensor feed back to high temperature signal in control
The heart, control centre control variable-frequency motor and keep normal power output, and thermostat valve 12 adjusts the flow of two sides oil outlet, keeps oil liquid equal
By oil-water- to-water heat exchanger 10, when oil liquid passes through oil-water- to-water heat exchanger 10, blower 20 works, will be in cooling water tank 5 by water pump
Water is sent into oil-water- to-water heat exchanger 10, persistently carries out cooling to oil liquid until oil liquid temperature is between 25 DEG C~40 DEG C, then warm
Valve 12 is controlled according to oil liquid temperature, the flow of two sides oil outlet is adjusted, gradually decreases the flow that oil liquid flows through oil-water- to-water heat exchanger 10,
Until the oil liquid flow in oil-water- to-water heat exchanger 10 is zero, blower 20 and water pump 7 stop working, to save electric energy.
