Centrifugal pump installation considerations

1. According to the basic size of the concrete foundation, at the same time to bury the anchor bolts. 2. Centrifugal pump and motor should be checked before installation, all parts should be intact, the pump should be no debris. 3. The unit on the basis of the base plate and placed between the wedge pad, adjust the wedge pad to find the level of the centrifugal pump. After adjusting, tighten the anchor bolts. 4. Centrifugal pump suction, discharge pipe should be scaffold, can not be used to pump support. Import and export pipe diameter should be consistent with the pump import and export caliber. 5. Self-priming pump should be installed before the entrance pipe, fill the liquid and then outlet pipe, correction steering. Pump inlet pipe must be matched with the pump, and the total length of not more than 5 meters, otherwise it will affect the self-priming performance, self-priming height can be simply calculated according to the right formula: Self-priming 3m water / water density = actual self-priming height. 6. Installation is completed, and finally turn the coupling by hand, check whether the phenomenon of rub touch, turn the installation is completed easily. 7. Magnetic pumps are strictly prohibited with the extraction of particles and easy to crystallize the media, does not allow the closure of the discharge port in the case of continuous operation, the need to maintain a minimum flow. 8. In order to prevent debris from entering the pump, a filter should be set up at the inlet. The filtration area should be more than 3 ~ 4 times of the pipe cross-sectional area. 9. Centrifugal pump head high in the export pipeline should also be installed check valve to prevent water hammer suddenly shut down damage.
