Specific embodiment
As shown in Figure 1：After being operated first manual operation platform 17 and the sending enabling signal of industrial personal computer 18,9 energization work of heater
Make, when oil temperature local in fuel tank 8 rises to set temperature, PLC controller 16 controls the first secondary loop 15 and connects, first to
4th solenoid valve 1,2,3,4 is closed respectively, and the 5th solenoid valve 5 is opened, three screw pump M1 starting, oil outlet of the lubricating oil from fuel tank
A outflow flows back into fuel tank into the first secondary loop 15 by filter 13, cooler C1, flow sensor 14, realizes pre-
The purpose of hot lubricating oil.In this stage, temperature sensor 7 is completed to acquire the temperature of lubricating oil in fuel tank 8 in real time and feeds back to PLC
Controller 16 and industrial personal computer 18.When oil temperature meets set temperature, dynamic pressure three screw pump M1 stops working, and warm-up phase is completed.
Second step, PLC controller 16, which issues signal, opens first to fourth solenoid valve 1,2,3,4, and the 5th solenoid valve 5 closes
It closes.Dynamic pressure three screw pump M1 starts to work, and to after a certain period of time, high-pressure pump M2 starting, high-voltage oil liquid is by filter 13, cooling
Device C1, flow sensor 14 flow to left and right spring bearing 19,21 respectively, and high pressure oil lifts each bearing.At the same time, another portion
Transfer pressure lubricating oil flows separately through first to fourth solenoid valve 1,2,3,4 and enters left and right spring bearing 19,21 and experiment bearing 20.
Some oil liquid flows through second subprime circuit 15 ' and flows back to fuel tank 8 by oil quality on-line computing model 6 to oil return opening B.Into
One step, PLC controller 16 issues signal, testing stand electric motor starting, and main shaft 12 starts to rotate.When 20 the operation is stable of test bearing
To when forming complete dynamic pressure oil film, high-pressure pump M2 stops working.Testing stand working stage, flow sensor 14, temperature sensing
6 real-time monitoring lubricating oil parameters of device 7 and oil quality on-line computing model.When temperature is more than preset temperature, cooler
C1 starts to work, and is lowered into the oil temperature of the lubricating oil of bearing.Oil liquid on-line computing model 6 can be to particle contamination in lubricating oil
Object, water content and dynamic viscosity do real-time monitoring.When any one of its index, which reaches pre-, posts a cordon, system can be at once
It alarms and stops motor work.
