When the foundation of double suction pump manufacturer is grouted once, the position of anchor bolt hole of pump base and motor base shall be reserved. The foundation surface of primary grouting shall be 20-40mm lower than the lower plane of unit base plate for secondary grouting. When the pump and motor can be placed after the cement is dry and fixed, the pump base shall be fully grouted without cavities, and the grouting shall be carried out continuously without long-term interruption. The quality of grouting directly affects the vibration and noise of the pump unit, so be careful
The equipment installation and preliminary alignment of double suction pump manufacturer are for the unit with base. After the base is placed on the foundation surface, use wedge block or cushion block to level the base plate, use level meter to align, and the levelness tolerance is not more than 0.1M m/m. Then place the device. Loosen the connecting bolts of the pump and motor coupling, check the axial clearance value (see the outline dimension drawing for the clearance value) on several points in the circumferential direction of the pump and motor coupling, and the end face deviation is ≤ 0.06mm; use a straight gauge (knife edge ruler) to cross the pump and motor coupling, and check the alignment of the pump and motor coupling, and the outer circle deviation is ≤ 0.10mm.
For the secondary grouting of pump base and motor base of double suction pump manufacturer, for the split pump and motor, the welded common base is used. Considering its rigidity, it is recommended that the common base is also buried in the concrete, leaving only the upper layer of the common base exposed.
