Centrifugal horizontal pump installation steps:
(1) The horizontal pump unit is transported to the site, and the motor is installed if the base is attached. It is not necessary to remove the pump and motor when leveling the base.
(2) Put the base on the foundation, put a wedge-shaped horn near the anchor bolts, raise the base by 20-40 mm, and prepare to fill it with grout after leveling.
(3) Check the levelness of the base with a spirit level. After leveling, tighten the anchor nut and fill the base with cement slurry. After the cement dries, check the level again.
(4) When the power of the unit is large, the pump, motor and base may be packaged separately in order to facilitate transportation. At this time, the user needs to install and calibrate the pump unit by itself. The method is as follows:
A. Wash the dirt on the support plane of the base, the feet of the water pump and the feet of the motor, and put the water pump and the motor on the base.
B. Adjust the level of the pump shaft, and tighten the nut appropriately after leveling to prevent it from moving.
C. Lift the motor, make the pump coupling and the motor coupling match, and lower the motor to the end to make the corresponding position;
d. Adjust the gap between the two couplings to about 5mm, and correct whether the axis lines of the motor shaft and the pump shaft coincide. The method is to put a flat ruler on the coupling, and the outer circle of the two couplings is level with the flat ruler. , If it does not coincide, the relative position of the motor or pump should be adjusted, or the pad should be adjusted with a sheet;
e. In order to check the accuracy of the installation, the gap between the two coupling planes should be measured with a feeler gauge at several different positions on the circumference of the coupling. The maximum and minimum gap difference on the coupling plane must not exceed 0.3 mm. The difference between the top and bottom or left and right of the end center line must not exceed 0.1 mm.
(5) When the unit does not have a base, it needs to be installed directly on the foundation. The method is similar to 4, but more attention should be paid to the correction.
