According to the above method, select 4 test pressure points from 5% of the rated pressure to the same pressure of 5% of the rated pressure. At each test pressure point, the test horse's strength and oil temperature should be lower than -2D47. Under no-load conditions, start the test at low speed and fixed speed for five times. Oil viscosity inspection: Under the specified conditions, the oil is reduced by 1 hour, and the engine is continuously running for 1 hour. The oil viscosity should be measured according to the design requirements at high speed or 125% of the rated speed (the higher one). Test the no-load pressure and rated pressure and continue to rotate for 15 minutes. Under rated speed, perform reverse operation test at the maximum pressure or 25% of the rated bed force (the higher one shall be selected): During the test, the oil supply is 300 knots, the delivery rate is 101 and the test is carried out at 112Hz (one reciprocating stroke) and a period of 1, under constant T conditions.

At the rated speed, the oil resistance is 30~60℃ for reverse rotation test, in which the shaft distribution structure type runs forward and reverse for 10h each: the flat oil distribution type runs forward and reverse for 125h each. In the continuous operation process, regularly measure the customer's efficiency (or leakage adjustment), the factory oil wet change motor external light quantity high temperature, etc.
Under the rated.L, the imported oil 30-G0 number of continuous combustion operation test, in which the shaft distribution structure type runs forward and reverse for 400h each: the flat energy configuration type runs forward and reverse for 400h each. Reverse and run for 500h each. During continuous rotation, measure the volumetric efficiency (or external leakage) regularly, the oil inlet is reliable, the external light volume is high, etc.
