The pipe length between the suction surface of the vortex sewage self-priming pump and the pump inlet should be less than the pump mounting height plus 2. The difference is that the backwater does not flow to the outer edge of the impeller, but to the impeller inlet. When the self-priming pump is activated, the reflux valve under the front of the impeller must be opened so that the liquid flow in the pump returns to the impeller inlet. The water is mixed with the air from the tube under the b of high speed rotation of the impeller, bing a mixture of gas and water to the separation chamber. Here the air is discharged and the water is returned from the reflux valve to the impeller inlet. So repeated until the air drained and sucked in the water. Flow along the worm shell. As the liquid in the worm shell constantly impact the cascade, constantly crushed by the impeller, with the air strongly mixed mixing, the bation of gas-water mixture, and continuous flow caused by the gas water can not be separated. The mixture is stripped by the tongue at the outlet of the worm shell and enters the separation chamber along the short tube. In the separation chamber the air is separated and drained by the outlet tube, while the water still flows through the left and right backwater holes to the outer edge of the impeller and is mixed with the tube air.

In order to make its sewage self-priming pump suction pipe will not appear the phenomenon of gas accumulation, sewage self-suction pump suction pipe requirements of the fewer elbow the better, up to one elbow is appropriate, suction water to the pump import should be arranged in the way of slope upward to avoid the phenomenon of accumulation of gas. In order to ensure that the sewage self-suction pump suction pipe compleby sealed non-leaking phenomenon of sewage self-priming pump suction pipe should not be increased and reduced. Sewage self-suction pump suction pipe Increased after the pipeline will have a large number of gas is not easy to clean, sewage self-suction pump self-suction exhaust time after the pump body inside the water will change heat pump body hot, will lead to sewage self-suction pump can not absorb liquid, sewage self-suction pump suction pipe shrinkage, Because the export is larger than the import and the discharge of large flow of traffic caused by the import flow can not keep up with the export flow, so there will be a failure. Sewage self-priming pump suction pipeline requirements of quality and material requirements are very strict. Therefore, water suction pipes usually use steel tubes or PVC tubes.

This is not the type of other pumps. ISG Vertical Pipeline Centrifugal Pump Installation Instructions: 1, pipeline centrifugal pump before installation should check the unit fastener has no loosening phenomenon, pump body flow channel has no foreign body blockage, so as to avoid damage to the impeller and pump body when the pump is running. ISG Vertical pipe centrifugal pump installation When the weight of the pipe should not be added to the pump, so as not to deb the pump. Pipeline centrifugal pump installation must tighten the foot bolts, so as to avoid the impact of vibration on the pump perbance. In order to facilitate the maintenance of pipeline centrifugal pump and safe use, in the pump import and export pipe on each installation of a control valve and in the pump outlet near the installation of a pressure gauge to ensure that the operation within the rated lift and flow range, to ensure the normal operation of the pump, increase the service life of the pump. Pipeline centrifugal pump after installation to toggle the pump shaft, impeller should be no friction or card death phenomenon, otherwise the pump should be disassembled to check the cause.
