Horizontal multi-stage centrifugal pump installation order (1) The unit shipped to the scene, with the base has been installed motor, leveling base can be removed without having to pump and motor. (2) The base on the ground, near the anchor in the ground pad wedge-shaped horn, the base pad 20 to 40 mm high, ready to level after filling the slurry used. (3) Check the level of the base with a level meter, flatten the foot nut to fill the base with grout, until the cement should be checked again after the level of dryness. (4) When the unit power is large, in order to facilitate the transportation, the pump, the motor and the base may be packed separately. In this case, users are required to install and correct the pump unit by themselves. The method is as follows: a. Remove the dirt on the support surface of the base, the pump foot, and the motor foot, and remove the pump and motor onto the base. b. Adjust the pump shaft level, tighten the nut properly after leveling to prevent ambulation. c. Lifting the motor so that the pump coupling and the motor coupling cooperate, put down the motor to do the appropriate position in the end; d. adjust the gap between the two coupling is about 5mm, and the correction of motor shaft and pump shaft axis coincide, the method is to place the flat ruler on the coupling, the two coupling cylindrical and flat feet phase , If not overlap, should adjust the relative position of the motor or pump, or pad to adjust the 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 difference between the maximum and minimum clearances on the plane of the coupling must not exceed 0.3 mm. The centerline of the difference between the upper and lower sides or not more than 0.1 mm. (5) When the unit is not with the base, you need to install directly on the basis of the method similar to 4, but should pay more attention to the correction.
