Horizontal multi-stage centrifugal pump order correct installation

To master the correct installation sequence, can better use the horizontal multi-stage centrifugal pump, and we all know horizontal multi-stage centrifugal pump with high efficiency, wide range of performance, smooth running safety, low noise, long life, easy installation and maintenance, etc. Therefore understanding the horizontal multi-stage centrifugal pump is necessary to correct installation order.

Horizontal multi-stage centrifugal pump installation order:

(1) unit shipped to the scene, the supplementary motor base have been installed, the leveling base can not unload the pump and motor.

(2) base on the foundation, cushion wedge iron near ground screw, will be the base mat 20 ~ 40 mm, preparation of filling slurry after leveling.

(3) use level to check the levelness of the base, pull tight anchor nut water base mud filling after leveling, after being dry cement should check the levelness again.

(4) when the unit power is larger, in order to facilitate transport may be the pump, motor and base separate packing, that requires users to install at this moment, correction of pump unit, the method such as washing:

A. will support base plane, water pump motor, dirt washed out of the plane of the net, and put the pump and motor in the base.

B. adjust pump shaft level, appropriate to tighten the nut after leveling, in case of walking.

C. hoist motor, so that the pump coupling and motor coupling to cooperate, put on the motor did;

D. adjust two coupling gap is about 5 mm, and the correction of motor shaft and pump shaft axis coincidence, the method is to put the ruler on the coupling, two couplings and the cylindrical flat feet flat, if do not overlap, should adjust the relative position of motor or pump, or pad to chip to adjust;

E. in order to check the accuracy of the installation should on the coupling on the circumference of a few different positions with feeler clearance in the plane of the two coupling, coupling plane week difference maximum and minimum clearance shall not be over 0.3 mm. Both ends of the center line of the up and down or left and right sides of difference may not be over 0.1 mm.

(5) when the unit without the base, is installed directly on foundation, its methods and 4 are similar, but should pay more attention to correction.

Above is correct horizontal multi-stage centrifugal pump installation order, hope to be able to cause enough attention, you that subsequent to better use of horizontal multi-stage centrifugal pump.
