1. The installation of the overall unit of the centrifugal unit should be placed directly on the basis of the pair -paired cushion iron.
2. The centrifugal fans assembled on the spot should be properly protected by the cutting surface on the base. When there should be rust or operation, when the base is placed on the basis, it should be used to flatten the oblique pad iron.
3. The bearing seat and the base should be closely coordinated, and the vertical non -horizontal degree should not exceed 0.2/1000. Use the horizontal meter to measure on the main shaft.Measurement.
4. Before scraping the bearing, the rotor axis heart line should be corrected with the case axis heart line. At the same time, the gap between the gap between the impeller and the air inlet and the gap between the main shaft and the back of the shellRegulations of the file.
5. When assembling the main axis and bearing, check in accordance with the provisions of the equipment technical file.Between the bearing cover and the bearing tile, the survey of 0.03 ~ 0.04 mm (measuring the outer diameter and the inner diameter of the bearing seat of the bearing) should be maintained.
6. When assembling the fan case, find the position of the shell on the basis of the rotor axis and the axial and radial gap at the axial and radial gap between the impeller and the air inlet of the air inletInside, check whether the ground foot bolts are tight.When the gap value is irregularly specified, the general axial gap should be 1/100 of the outer diameter of the impeller, and the radial gap should be evenly distributed.Those with small diameter take a large value).When adjusting, strive for a small gap value to improve the wind turbine efficiency.
7. When the fan is found, the different axis of the fan shaft and the motor shaft: radial positioning shift should not exceed 0.05 mm, and the tilt should not exceed 0.2/1000.
8. The centrifugal fans of the rolling bearing are equipped with the different axis of the upper bearing holes of the two bearing frames. After the rotor can be installed, the rotation is flexible.
