Self suction pump suction pipe for pump self-priming performance and operation has a great impact, only the correct design, manufacture, installation, in order to ensure the self suction pump in normal use. Self priming pump suction pipe manufacturing requirements have the following points.

    1, self suction pump suction pipe of the choice of materials is very strict, different situations require different materials. Water pipes often use steel or PVC pipe, if it is a large flow of self suction pump need convenient removable can adopt imported silica gel tube, or if the use of small self-priming pump can be used for lining of steel wire hose is convenient for disassembly and mobile.

    2, in order to make the self suction pump suction pipe does not appear to gas accumulation phenomenon, self suction pump suction piping requirements the number of elbow fewer is better, most a bend for appropriate, ceiling surface to the pump inlet should be the slope to the arrangement to avoid the gas accumulation phenomenon.

    3, self-priming pump suction pipe should not be increased and reduced, self suction pump suction pipe to increase inside the pipe will have a large number of gas is not easy to exhaust the net, self suction pump suction and discharge time is too long after the water inside the pump body will burn variable pump body, will lead to self - priming pump does not suck up liquids, self suction pump suction pipe, after narrowing, due to exports than imports for the discharge of high flow inhalation flow resulted in a small inlet flow and outlet flow so it will fail.

    4, a self suction pump suction pipe and self-priming pump suction pipe can not insert the pool depth is too shallow, because too shallow surface water in the water flow state inside will contain some of the air, it will also cause self suction pump suction on runoff phenomenon.

    Also, according to other relevant aspects of the flow rate of self-priming pump using the common thoughtful to choose suitable self-priming pump suction pipe, so as to achieve a multiplier effect.
