4 Technical requirements
4.1 Running performance
The oil-softening operation should be stable without abnormal phenomena. 4.2 Endurance
J8811.11 No. 98
The oil-filling case should be free of abnormal phenomena such as parts damage under a pressure 1.1 times the nominal pressure. 4. 3 Sealing performance
The system should not leak at any joint under 1.15 times the nominal pressure. 4.4 Oil flow
t The oil flow should not be less than 16L/tnin under the pressure of the public money. 4.5 The oil outlet and the refueling table should comply with the relevant standards. The surface of the oil storage channel should be smooth and no chain phenomenon is allowed. 4.6 The vertical length of the bacteria washed out by the foaming should not be more than 4m. 4.1 Life span
The life span should not exceed 10CC under the use conditions. When the oil flow is set to a certain value, it can be regarded as the actual service life limit
5 Test method
5.1 Test operation
JB/TB81I.1-
The factory test is for lubricating oil with a viscosity of 1.2~74.8mm/g, and the life test medium is a cone penetration of 265~29525C, 15g>1/10n fat. The basic range of the pressure gauge used for the test is 0-6MPa and the accuracy level is 2.5. 5.2 Principle diagram of the test system as shown in Figure 3
Test system: 8 positive pressure gauge: 3-adjustment bed reading
53 running test
The oil outlet pressure is measured to 94MPa. It is run for 5min and its running performance should comply with the provisions of 4.1. s.4 Performance test
The oil outlet pressure of the oil pump is adjusted to MTa, and its durability is tested for 5min. The pressure performance should meet the requirements of 2. 5. Width test questions
Pressure resistance test rating · Daily inspection of each connection + its sealing performance as specified in 4.3, S.6 state gasket test
will add sleeve spring out: 1 pressure is reduced to 4MFa. Measure the oil volume of the mountain contact 3n. Its half value is in accordance with the provisions of 4.4. 5, the surface coating Ji
monthly visual inspection plus independent surface &, its quality should meet the requirements of 4.5. 5.8 Cleanliness inspection
will be as mentioned above, the whole specification of all parts such as the oil through the oil (body part hidden), will be washed with the oil with the new oil stop temperature of 12C drying flat 60mm and you weight of the fixed paper through the paper model into the group (the building of the following baking m). The filter is weighed again after ten days. The difference between the amount of impurities and the amount before and after the re-weighing is T, and its value should meet the requirements of 1.5.9 life point
Inject the core oil to 11 positive pressure to 4MPa, and it must be 5h later. The fixed outlet lubrication volume should meet the requirements of 4.5. Inspection regulations
. Position inspection
JI/T811.1-199K
For example, the pump record control test technology 5.3, 5.4, 6.2, 5.6 and 5.7 shall be carried out. 2 Type inspection
5.2.1 Type inspection shall be conducted in any of the following cases: a) When the product is first modified and tested: b) When there are significant changes in the structure, material or process that may affect the product performance: ) When the product is completed and finished for 6 years normally
