Pump installation methods and precautions
Pump installation methods and precautions: First, the installation method and sequence of the pump: 1, the unit is placed on the foundation buried in the bolt, between the base and the foundation, with a pair of wedge pad with calibration. 2, release the coupling large, respectively, with the spirit level on the pump shaft and base, by adjusting the wedge pad, the unit level correction, appropriate tightening anchor bolts to prevent ambulation. 3, the correction of the concentricity of the pump shaft and the motor shaft, on the outer diameter of the coupling path, allowing 0.1 mm deviation; two coupling plane clearance should be guaranteed 2 to 4 mm, (small pump to take small) gap to be uniform, Tolerance of 0.3 mm. 4, pick up the pipeline and determine the direction of motor rotation, then connect the coupling, and then check the concentric ax again axis. 5, the actual test run in the unit after 2 to 3 hours for the final inspection, if no bad phenomenon, then that the installation of qualified. Check the temperature and vibration of the bearing during commissioning as follows:
