If voltage, if it is rotates the connecting terminal and the connecting terminal is fastened, return step (2), if otherwise executed
Step c；
Whether the thermocouple c. detected in oil pump control circuit acts, and if it is step d is executed, thens follow the steps g if not；
D. Oil pump electrical machinery insulation resistance is measured, judges whether the insulation resistance is greater than the first preset resistance, if it is
Execute step e, if otherwise replacing spare motor, return step (2)；
E. Oil pump electrical machinery D.C. resistance is measured, judges whether the D.C. resistance is greater than the second preset resistance, if it is
Execute step f, if otherwise replacing spare motor, return step (2)；
F. involution thermocouple, return step (2)；
G. oil pump control circuit insulation resistance is measured, judges whether the insulation resistance is greater than third preset resistance, if
It is to then follow the steps h, if otherwise switching control circuit, return step (2)；
H. Oil pump electrical machinery insulation resistance is measured, judges whether the insulation resistance is greater than the 4th preset resistance, if it is
Execute step e, if otherwise replacing emergency bearing oil pump, return step (2)；
I. Oil pump electrical machinery D.C. resistance is measured, judges whether the D.C. resistance is greater than the 5th preset resistance, if it is
Terminate, if otherwise replacing emergency bearing oil pump, return step (2).
