3.1 Quick month this standard insertion should be like the dirty JB267C list related provisions. Especially before the pull installation + shaft and other auxiliary parts of the dry operation temperature rise, inspection piece micro and inspection work box temperature.
3.2 Refer to the provisions of 3.1 in JR2670-83 to adjust the installation level, put a ruler on the working surface (or above), and the horizontal reading of the water level on it should not exceed 0.10/13.3 Before the inspection, the tools and inspection methods can be generally replaced, and the inspection items and requirements are arranged in the order of inspection. 3.4 When the actual micro length is different from the length specified in this standard, it should be converted according to the length that can be measured according to the provisions of 3.3.1.1 in 2670-82. When it is less than 0.0m, it is still calculated as 3.5 The "vertical" referred to in this standard refers to the self-supporting plane passing through the main shaft axis, the vertical axis and the center line of the base, longitudinal! The value number refers to the straight line through the axis and straight to the withdrawal plane. 3.6 The test items can be increased or decreased by agreement between the user and the manufacturer. The Ministry of Machinery Industry approved 170818 and implemented it in 1801-01 (No. 8600.1-1997).
