1. Place the unit on the foundation buried with anchor bolts, and use a pair of wedge pads for correction between the base and the foundation.
2. Loosen the large coupling, place a level meter on the pump shaft and the base separately, adjust the wedge pad to correct the unit level, and properly tighten the anchor bolts to prevent moving.
3. Correct the concentricity of the pump shaft and the motor shaft. On the outer circle of the coupling shaft, the allowable deviation is 0.1 mm; the gap between the two coupling planes should be 2 to 4 mm, and the gap should be even. The tolerance is 0.3 mm.
4. After connecting the pipeline and determining the direction of rotation of the motor, connect the coupling again and check the concentricity of the shaft again.
5. After the actual test operation of the unit for 2 to 3 hours, make a final inspection. If there is no bad phenomenon, the installation is considered qualified. During the trial operation, check the temperature and vibration of the bearing as follows:
6. During the installation process, in order to prevent debris from falling into the machine, all holes of the unit should be covered.
7. In order to prevent debris in the pipeline from entering the pump, a filter should be installed in the pump glue for the newly installed pipeline, and the effective section should be 2 to 3 times larger than the section of the suction pipe.
