3.! When using this standard, the relevant provisions of GB 1742.1.1 shall be referred to. In particular, the case, shaft and other parts before inspection shall be inspected. 3.2 According to the provisions of 3.1 in GB/T17421.1-1998, adjust the installation water level. The horizontal weight in the recognized direction and the direction shall not exceed 0.04/1000.
3.3 Before the inspection, the actual inspection order can be arranged according to the requirements of installation and disassembly. Tools and inspection convenience, thermal inspection items. 3.4 When the measured length is different from the length specified in this standard, the difference should be converted according to the length that can be measured according to the provisions of 2.3.1.1 in GB/T17421.1-1998. When the conversion is less than 0.001mm, it is calculated as 0.001mm. 3.5 When inspecting the working accuracy, the test should be carried out after fine grinding. 3.6. According to the agreement between the user and the demander, the inspection items can be increased or decreased.
