The plastic self-priming sanitary pump is a self-priming plastic water pump. Because of its corrosion resistance and high temperature resistance, it is favored by the machinery industry. Many people will struggle with the selection and do not know how to choose the right one. Before we talked about how to select the model, today we will tell you a piece of plastic self-priming sanitary centrifugal pump suction pipe installation methods and skills!
(1) In order to prevent air leakage in the suction pipe of the plastic self-priming sanitary negative pressure pump , the suction pipe must be completely sealed and no air can be sucked in. The suction pipe is usually made of steel pipe, and the joints are welded or flanged. .
(2) When the water in the suction pipe of the plastic self-priming centrifugal pump contains dissolved gas, it will escape due to the decrease in pressure in the pipe. If gas accumulates somewhere in the suction pipe, an air bag will be formed, which will affect the passage of the pipe. Water capacity. In severe cases, it will destroy the water absorption of the real house. In order to make the plastic self-priming centrifugal pump can discharge the gas in the suction pipe in time. The suction pipe should have a slope that continuously rises along the direction of the water flow. The gas in the pipe is discharged from the top of the pump casing at the inlet of the water pump.
(3) The installation and laying of the suction pipe of the plastic self-priming centrifugal pump should avoid the formation of air pockets in the pipe.
