Liquid-level switch II19 is located at the top of heater 20 in example.
A kind of motor oil cooling device, as shown in figure 3, including above-mentioned exhaust apparatus, oil pump 1, flowmeter 9, motor 7, changing
Hot device 2 and overflow valve 5；
Oil pump 1, pressure-bearing fuel tank 14, flowmeter 9, motor 7, heat exchanger 2 are sequentially connected to form a fluid loop；
Pressure-bearing fuel tank 14, overflow valve 5, oil pump 1 are sequentially connected to form second fluid loop；
Oil circuit between flowmeter 9 and the oil inlet 8 of motor 7 is provided with fuel feeding stop valve 10, the oil discharge outlet 6 of motor 7 with
Oil return stop valve 4 is provided between heat exchanger 2, the fluid porch of heat exchanger 2 is provided with draining valve 3, fuel feeding stop valve 10, oil return cut-off
Valve 4, overflow valve 5, draining valve 3 control by controller.
Heat exchanger 2 provides low-temperature receiver by compressor 22 and condenser 21, and compressor 22 and condenser 21 control by controller.
The oil-out of oil pump 1 is connected with the oil return opening of pressure-bearing fuel tank 14, oil-out and the phase of flowmeter 9 of pressure-bearing fuel tank 14
Even, flowmeter 9 is connected with the oil inlet 8 of motor 7, and the oil discharge outlet 6 of motor 7 is connected with the fluid entrance of heat exchanger 2, heat exchanger 2
Fluid outlet be connected with oil pump 1.
Oiling process：
The first step closes draining valve 3, opens pouring orifice stop valve 13, oil-feed port stop valve 10, is added from pouring orifice 12 cold
But filled with oil to flowmeter 9, be then shut off oil-feed port stop valve 10, continuously add cooling oil to pouring orifice stop valve 13
Place, oil return stop valve 4 is opened, continue to add the cooling oil dosage in motor 7 and in feeding and return line, close pouring orifice stop valve
13。
Second step opens overflow valve 5, fuel feeding stop valve 10, oil return stop valve 4, then open oil pump 1, regulation relief valve 5 to
Flow meets the technical requirements of motor 7 in flowmeter 9.
The oil cooling aggregate course of work：
Because fluid is to be pumped into pressure-bearing fuel tank 14 from the inflow heat exchanger 2 of motor 7, then from oil pump 1, a small amount of air can be brought into
Pressure-bearing fuel tank 14, because the inner fluid flow velocity of pressure-bearing fuel tank 14 is slow, gas can be risen to pressure-bearing by buoyancy in pressure-bearing fuel tank
The top slope of fuel tank 14 is flowed into discharge 18 along slope again.Because pressure-bearing fuel tank 14 only has one outlet and by exhaust electromagnetism
Valve 16 is closed, and gas aggregation can make oil level 23 in discharge decline the switch closure for triggering liquid-level switch I17 in discharge 18,
Exhaust solenoid valve 16 is controlled to open by controller.Because fluid is to be pumped into pressure-bearing fuel tank 14 from oil pump 1, so pressure-bearing fuel tank 14
Internal pressure superatmospheric is strong, and the excessive gas in discharge can be discharged by exhaust solenoid valve 16 from blast pipe 15.Work as gas
Oil level goes up in body discharge discharge, and liquid-level switch I17 switch can disconnect, and exhaust solenoid valve 16 can also close, and gas is no longer
Discharge.
If no discharge 18 and auxiliary equipment gas can assemble the space for causing gas to take in pressure-bearing fuel tank
Fluid discharge the change that motor causes the height of oil level 24 in motor from pressure-bearing fuel tank.
Because the diameter itself of discharge 18 is small, fluid surface area is small, discharge oil when oil level 23 declines in discharge
The volume of liquid is also relatively small.Because the fluid area in motor 7 is much larger than the inner fluid area of discharge 18, from discharge 18
The fluid of interior discharge is into level height variable quantity in motor after motor 7 just much smaller than the level height change in discharge 18
Amount, almost can be ignored, so as to reach the accurate control to oil level in motor 7.
The outlet temperature value that temperature sensor 11 is arranged on pressure-bearing fuel tank 14 goes out to be sent to controller, and controller sends heating
Instruction heater 20 will work the fluid that is flowed through from pressure-bearing fuel tank 14 of heating, and controller sends cooling signals compressor 22, cold
Condenser 21 will work to cool to the fluid for flowing through heat exchanger 2.How overflow valve 5 adjusts the fluid pumped out from oil pump 1 all
Oil pump 1 can be flowed into from heat exchanger 2, therefore all fluid pumped out from oil pump 1 can all participate in cooling down, without freezing individually plus all the way
Circulate to the fluid cooling in pressure-bearing mailbox 14, improve refrigerating efficiency.All fluid are all to firstly flow through after heat exchanger 2 cools to flow again
Enter oil pump 1, relatively colder oil can allow the temperature of oil pump 1 to reduce, reduce the loss to oil pump 1.
If system leakage, liquid level is dropped to below liquid-level switch II19, and liquid-level switch II19 will close together-cutting institute
There is the circuit of electrical appliance, ensure that heater 20 and oil pump 1 will not dry combustion methods.
Draining valve 3 is opened after use, the fluid in emptying system.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
