Pipeline pump, also known as pipeline centrifugal pump, is used to transport clean water and liquids with physical and chemical properties similar to clean water. It is also known as clean water centrifugal pump. We will explain to you the misconceptions of using pipeline pumps.
1. There are many elbows used on the inlet pipeline. If too many elbows are used on the inlet pipeline, it will increase local water flow resistance. And the elbow should turn in the vertical direction, and it is not allowed to turn in the horizontal direction to avoid gathering air.
When installing the inlet pipeline, the horizontal section should be horizontal or upward. This will cause air to accumulate in the inlet pipe, reduce the vacuum degree of the water pipe and pipeline pump, reduce the suction head of the pipeline centrifugal pump, and reduce the water output. The correct approach is to tilt the horizontal section slightly towards the direction of the water source, not horizontally, and not upward.
3. The water pump inlet is directly connected to the elbow. This will cause uneven distribution of water flow through the elbow and into the impeller. When the diameter of the inlet pipe is greater than that of the water pump inlet, an eccentric reducing pipe should be installed. The flat part of the eccentric reducer should be installed above, and the inclined part should be installed below. Otherwise, air will accumulate, water output will decrease or water cannot be pumped, and there will be a sound of impact. If the diameter of the inlet pipe is equal to that of the water pump inlet, a straight pipe should be added between the inlet and the elbow, and the length of the straight pipe should not be less than 2-3 times the diameter of the water pipe.
The next section of the inlet pipe equipped with a bottom valve is not vertical. If installed in this way, the valve cannot close on its own, causing water leakage. The correct installation method for the water pump manufacturer is to install the inlet pipe with a bottom valve, and the next section is vertical. If vertical installation is not possible due to terrain conditions, the angle between the water pipe axis and the horizontal plane should be above 60 °.
