Introduction to the installation sequence of horizontal multistage centrifugal pumps

(1) The unit is transported to the site, and the motor with the base is installed. It is not necessary to remove the water pump and motor when leveling the base.

(2) Place the base on the foundation, pad the wedge-shaped horn near the anchor screw, and place the base cushion 20~40 mm high, ready to be leveled and filled with cement slurry.

(3) Check the level of the base with a level meter. After leveling, tighten the foot nut to fill the base with cement slurry. After the cement is dry, check the level again.

(4) When the power of the unit is large, the pump, motor and base may be separately packaged for convenient transportation. At this time, the user needs to install it himself and calibrate the pump unit. The method is as follows:

a. Clean the dirt on the support plane of the base, the pump foot, and the motor foot, and place the pump and motor on the base.

b. Adjust the pump shaft level, and tighten the nut properly after leveling to prevent walking.

c. Lift the motor to match the pump coupling and the motor coupling, and lower the motor to the corresponding position;

d. Adjust the gap between the two couplings to about 5mm, and correct whether the shaft line of the motor shaft and the pump shaft coincide. The method is to place the flat ruler on the coupling, and the outer circumference of the two couplings is level with the flat ruler. If not coincident, adjust the relative position of the motor or pump, or adjust the pad with a thin sheet;

e. In order to check the accuracy of the installation, the clearance of the plane of the two couplings should be measured with a feeler gauge at several different positions on the circumference of the coupling. The difference between the small gap of Zui and Zui on the plane of the coupling should not exceed 0.3 mm. The difference between the lower or left and right center lines must not exceed 0.1 mm.

(5) When the unit does not have a base, it needs to be installed directly on the basis. The method is similar to 4, but more attention should be paid to correction.
