6.4.1.2.1 Running-in: In your weighing At speed, starting from no-load pressure, the output pressure of the crankshaft is about 25%, 40%, 55%, 5%, 10% and 10% of the nominal pressure. Avoid step loading and step connection. The running-in time under each level of pressure is not less than 1 minute, and the running-in time under nominal pressure is not less than 2 minutes. 6.4, 1.2.2 Test items, contents and methods shall be in accordance with the provisions of Table 4.

Contents and methods
Start the test system at nominal speed and air pressure: Measure the displacement at nominal pressure after running for 2 minutes, and measure the volumetric efficiency at nominal pressure. , the total volume rate
is large displacement, standard speed and 1.25 times the nominal weight, and the reverse operation is not less than 1min at the tail of the oil mountain is 18MP, and the test system is started and stopped for not less than> times in the above test. The separation of the rod production seat seal is not increased, the leakage volume is 1! Under the speed of the test person, the outlet pressure of the test is gradually increased by about 25% of the nominal pressure. The test state is determined after the test is related to the performance data: 2] The above method is reached, and the output power is 40%, 58%, 1%, and 1% of the nominal pressure, respectively. The relevant data of the test room are: 3) When the speed is about 1%, 85%, 70%, 5%, and 10% of the nominal speed, the above test points are respectively measured for the type of loss of the electric head:
4) The standard transfer rush is 2 0.35T, respectively measure the efficiency of each pressure point above the nominal range in the empty small space:

maximum discharge monitoring, nominal shift and 1.2 times the nominal pressure, for continuous operation test, note that during operation, regularly cut The efficiency of the warning volume
is calculated by the volume of the dripping liquid when the volume is 1.05ml. 2. Measure the fixed point, speed and time of each section. The method is not less than 3; 3. The continuous operation time is the source of the test time. S
