1.1 Foundation
All pumping units are on the same foundation. The function of foundation is to support and immobilize the pumping unit, make it run stably, avoid severe vibration. Therefore, the requirements for the foundation are as follows:
1) The foundation for the whole pumping unit must be concrete. Its size must be same as regulated.
2) Leave some anchoring holes on the foundation. Pour concrete to the holes after the pumping unit has been put on its position. This way may take some trouble, but as the bolts have been put into the anchoring holes on the pump base beforehand during construction, the pumping unit can be installed fluently.
3) The foundation bolts should reach out long enough so as to provide enough room for adjustment of the pumping unit. Reach out length=the length of anchoring hole on pump base+the thickness of washers+the thickness of nuts+15~20 mm
4) Large pumping unit has no integrated pump base, but separate bases for pump motor and pump head. Both the two bases should be horizontal. You can measure it with gradienter or spirit level.
Single stage double suction centrifugal pump installation
1) Before installation, you should check if the pumping unit is damaged during transportation. If the pumping unit has an integrated base, You should check and confirm if there is relative shift between the coupling of pump head and the coupling of pump motor. If so, adjust to make them coaxial.
2) Adjust the pumping unit to make it horizontal and coaxial. You should prepare steel plates of different thickness or iron wedges for adjustment. Make adjustment on condition that the pumping unit is standing stably and the nuts are bearing some pressure. Don't tighten the nut when there is clearance around the foundation bolt between the foundation and the pump base.
3) When adjusting the pumping unit, you should take off the elastic pin (in case of pumping units with integrated pump base). If the coupling of pump head and the coupling of pump motor are independent from each other, you should adjust their relative position.
