AI Test of the life of the main parts of the product A1.1 The test of the life of the main parts of the product should be carried out in the threaded connection under temperature, static load and without adding dripping agent:
A1.2 The basic dimensions of the thread and end thread of M6--M100 should comply with the provisions of GB196, and the thread tolerance should be within 6H6g according to the provisions of GB197, and the thread roughness should not be less than 6.3m. A1.3M 6~M42 The performance of the machine parts of the frequency-sensitive parts shall comply with the regulations of B3098.1~3098.$. A1.4 The test screw strength level: When the broken bolt diameter d is the maximum value of the screw efficiency range in Table 1, it is 5.6 level, and the minimum repair time is 5.R level. The length of the explosion control 1 should meet the requirements of 4.25. 41.5 The life test shall ensure that the sliding parts and operation methods specified in the product maintenance manual are met. During the life test, the subsequent maintenance work specified in the product maintenance manual is allowed to be carried out in parallel (such as regular disassembly and repair, additional cleaning and lubrication, replacement of plugs, etc.).
1.7 The working pressure during the test is 0. 49--0 3MP (Table 1.1). If the bursting bolt strength level of the monthly life test is 10.9 and meets the requirements of B525, the loss of 3 protective screw inspection can be reduced by 25%:
