5.3Nominal pressure side, oil output can not rely on small table 1 ship compensation, S.4 standard elimination parts 5.5 The appearance of the surface is smooth, without corrosion, scratches and other defects. 5.6 Under the nominal pressure, after the distributor is working, the oil outlet of each oil outlet of the distributor should be measured. The oil outlet should be more than ten times the value specified in the table. 5.7 Under the nominal pressure, when the distributor is feeding the oil, the oil outlet of each oil outlet should be the same. The difference should be 2M5.8 During the test, the connection parts should not be sealed. 5. During the test, the leakage of each oil outlet per minute should not be greater than 5 times the impulse rate specified in Table 1. 5. Under the annual load, the distribution of the work of not less than 150,000 times, the cleanliness limit of the public distribution should not exceed × 1/unit (the number of distributors) (test method 6.1 Test system 6. 1 Reduce the test medium, use rr~ plastic base when deep, 6.1.2 Test ring culture temperature: 15~
