The suction pipe of the self priming pump has great influence on the self suction performance and operation of the pump. Only by correctly designing, manufacturing and installing can we ensure the proper use of the self priming pump. The following points are required for the manufacture of the suction pipe of the self suction pump.

1. The selection material of the suction pipe of the self suction pump is more strict, and different manufacturing materials are needed in different conditions. Suction pipes usually use steel pipes or PVC pipes. If the large flow self priming pump needs to be disassembled easily, the imported silicone tube can be used. Or if the small self priming pump is used, the hose with steel wire can also be easily disassembled and moved.

2, in order to make the self-priming pump water pipe will not occur gas accumulation phenomenon, since the required number of elbow suction pump suction pipe less, at most one elbow is appropriate, the water suction pump inlet should be used to ramp up layout so as to avoid the phenomenon of gas deposition.

3, self-priming pump suction pipe should not be increased and reduced, which after the suction pump suction pipe to increase the pipeline will have a lot of gas is not easy to drain, self suction pump after pump suction and exhaust time of water inside the pump body will become hot, will lead to self suction pump to suck the liquid after. Narrow self suction pump suction pipe, due to exports than imports and discharge flow inhalation of small flow led to the import flow can not keep up the outlet flow so there will be trouble.

4, self suction pump suction pipe requirements, as well as self priming pump suction pipe can not be inserted into the pool depth is too shallow, because too shallow water surface is in the mobile state, water will contain some air, which will also lead to self priming pump can not suck up the phenomenon of water.

In addition, according to the flow rate and other related aspects of self-priming pump, we can consider the relevant aspects to make the right suction pipe, so that we can get twice the result with half the effort.
