The service life of the distributor shall not be less than 5000 times. When the supply amount of the supply port is less than 8 of the minimum value of the specified quantity, it is considered that the service life of the distributor has been limited
5 Test method
5.1 Test medium
The test medium of the distributor is N69 mechanical oil (except for the individual test medium). The oil supply amount is 13nm./mim.5.2 Principle of the test system
The distribution system is as follows, 4 as shown in the figure, 8
1 an electric LiDONG; 2 a low pressure street, 5 a pressure night: 1 a high speed connection: 6 a block: 7 a tube); 6 a legal distributor 1-junction 7 flow: 1-relay: 11-meter: 12-opening text figure 1 test system principle diagram
5.3 Dynamic pressure test
User dynamic electric system, adjust the high stop flow valve 5. The system standard power source to 30M, the fast direction flash 4 required position adjustment reading monitoring flow valve 2, the system power source 1.MH, the distributor is in the test: 1 yuan back pressure. The oil supply amount is the maximum, the car should move: 6 reversing room to do a sample test. 5.4 Filtration loss test
Set the two positions to 3CMI, all single lubrication parts, and measure the new oil supply port. The compensation should meet the requirements of 4.2. 5.5 Test of filter parts
The system pressure is MP: When the pressure is maintained for 2m, check the external seals of the distributor. There should be no leakage phenomenon: After the reversing, make a sample verification.
5.6 Test of oil supply
5.6.1 Adjust all oil supply to the maximum, without back pressure, and measure the consumption of each oil supply for 10 times. The consumption should meet the requirements of 1.2.1.
5.6.2 Adjust the oil supply rate of all the distributors to the maximum value. Adjust the oil supply rate to 15MPA, and measure each supply port twice. The value should meet the requirements of 4.4.2.
5.7 Function test
JB/T 8462-96
When the distributor with limit switch is running, use a meter to measure the contact point at the close position. When the indicating rod is extended and retracted, the corresponding contact point is connected or disconnected.
5.8 Lubrication inspection
Disassemble the distributor, select all the parts that have been oiled by the hot flushing, and pass the hot flushing film through the quantitative filter paper weighed on it at a temperature of 120 for 60m, and then cut the filter paper into a hot flushing machine at a temperature of 120, and take out the hot flushing film and weigh it again. The difference between the amount of filter paper after melting and before delivery is the impurity hair. Its use should comply with the provisions of 4.6 standard.
5.9 life test
The life test of the distributor is carried out on the lock-in working condition test bench. The test medium is grease with a strength of not less than 2 (25): 10gmr. All oil ports of the distributor are oiled to the maximum back pressure. After running 6 times, the oil supply test is carried out according to the provisions of 5.6.1. The method should comply with the provisions of 4.4. <Inspection rules
6.1 Factory inspection route
Distributor factory inspection is carried out according to 5.A, 5.4.5.5, 5.6.1 and 5.7. 6.2 Type inspection
. 2. If the following conditions are met, type inspection should be carried out carefully! First trial production, finalization appraisal;
b) When the structure, material, and process have significant changes that can affect the product performance:) Normal production and full working years.
6.2.2 Type inspection of products that have been tested or have been taken out of the product should be recorded every time. 6.2.5 Type inspection should be carried out according to the provisions of the school. 6.3 If there are any items that do not meet the test requirements, they should be inspected again. If there are any items that do not meet the test requirements, the product will be deemed unqualified. The marking, labeling and packaging of the product should comply with the provisions of the JG.
