Self-priming pump should how to install & what matter need pay attention to ?

 

Self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. Pipeline does not need to install the bottom valve, before the work only to ensure that there is a quantitative primer in the pump body. Different liquid can use different materials of self-priming pump. So the purchase of self-priming pump, how to install, and should pay attention to what matters? Now please pump industry chief editor for us to explain how to install self-priming pump.

 

 

Self-priming pump installation precautions

 

1. Before installing the self-priming pump, we should check carefully whether the bolts of the self-priming pump are loose, and whether there is any foreign matter falling into the pump body incase damage the impeller when the self-priming pump is running.

 

2. Put the self-priming pump on the concrete foundation, put the isolation pad between the bottom plate and the foundation, and find the level of the pump by adjusting the level of the isolation pad, and tighten the bolts after adjustment.

 

3. Before the installation of the self-priming pump, the fire pump manufacturer should do a good job of the appropriate concrete foundation according to the basic size of the self-priming pump, and in the process of doing the concrete foundation, the anchor bolts should be embedded well. Do concrete foundation refers to the large self-priming pump products, small self-priming pump is not necessary to do concrete foundation.

 

4. When the inlet and outlet of the self-priming pump are met with dust cover, the dust cover should be removed in connection with the pipe. It should be noted that if the fastest self-priming pump product is used, the outlet pipe must be turned after 1 meter vertical upward, otherwise the water diversion in the pump body is easy to be drained in the process of self-priming.

 

5, in order to convenient maintenance and safety, the inlet and outlet pipe of the self-priming pump should be installed a regulating valve, also need install a pressure gauge between the outlet valve and the pump, in order to ensure that the fire pump manufacturer certificate self-priming pump in rated flow and head range of use, so as to achieve the normal operation of the self-priming pump to extend the service life of the pump.

 

6. Before the self-priming pump is installed and started, the pump shaft should be moved at the same time to fill the pump chamber with liquid, so that the liquid is filled with the pump chamber to achieve the purpose of exhaust. To check whether the pump has leakage phenomenon, the impeller should have no friction sound or stuck phenomenon, if there is friction sound or stuck phenomenon, the pump should be disassembled and check the specific reasons and solve the problem.

 

7, the suction pipe and outlet pipe of the self-priming pump can not rely on the pump to support, but need a separate bracket to support the import and export pipe, and the caliber of the import and export pipe should be consistent with the caliber of the self-priming pump, especially the inlet pipe can not be enlarged, enlarged will affect the height of the self-priming pump, if the inlet pipe of the self-priming pump is reduced when installed, The export pipeline must also be reduced, we suggest that it is better to configure the corresponding pipeline according to the factory standard caliber.
