STest method
5.1 Test medium
The test medium of the distributor is N63 oil (except for the test medium, the oil supply is 120t.na. 5.2 Test principle
The test system principle of the distributor is shown in Figure 4. 5.3 Pressure test
Start the oil pump, and the distributor moves 2 times. Loosen the two holes and close the two screws to discharge the air. Test the pressure gauge, and its indication should meet the current requirements of small 1. 5.4 Sealing test
Re-adjust the back pressure of all oil outlets of the distributor to 10M, run rn, and visually check the external seals of the distributor. There should be no reading phenomenon. ||t t||5.5 Test the oil volume
Block all the feed pools, adjust the pressure of the feed pool to 1Pa and run for 3mi-respectively. The average compensation should meet the requirements of 4.3.
5.6 Test the oil tray
Adjust the oil pressure of the two pieces to 1CMPs, and the two pieces of the even number to 3MPE. Test each feed pool! U change the momentum. Then adjust the oil back pressure on both sides of the odd number to 3MP: adjust the oil back pressure of the oil outlet to 10MP and then test the oil outlet 18 times. The values ​​should meet the requirements of 1,4. 5. T Clearance Method | |tt||Disassemble the distributor, wash all the parts with the changed aldehyde, filter the petroleum scale with the discarded paper with fixed weight after drying in the oven at 12℃ for 60min and weigh it, then put the paper with a low concentration of 1g in the box and weigh the paper before and after the test. The value should meet the requirements of 4.
5.B Life test
