Pipeline pump installation considerations

Pressurized pipeline pumps can increase water pressure. In our lives, it is often the case that residents on high floors do not get water because of insufficient water pressure. However, the installation of pipeline pumps is a science, and it is not free to install them.

First of all, we have to determine the suction stroke of the pipeline pump, that is, the vertical distance between the centerline of the pipeline pump impeller and the pump suction surface. On the nameplate of the pipeline pump, we will find a value of “allow to suck vacuum height”, which is related to what we said but it has some correlation with suction stroke, but it is not what we call suction stroke. The "allowed vacuum suction height value" is measured at 1 standard atmospheric pressure and a water temperature of 20°C. However, when we use it under the influence of different environments, the values ​​will deviate. In addition, in practical use, the loss of the lift in the pipeline during the suction should also be considered. The installation height (suction stroke) = "Allow suction vacuum height" - "Pipeline loss head". Thus we can see that the installation height of the pipeline pump is affected by the pipeline resistance. We should consider reducing the pipeline length and the inflection point of the pipeline when installing the pipeline.

After installation, check the leak tightness of the suction pipe. If leakage occurs, it will not only damage the vacuum of the pump inlet of the pipeline pump, affect the amount of water, but also cause water pollution, so care should be taken.

Tips: When purchasing pipeline pumps, it should be noted whether the equipment has a sanitation license issued by the government's health supervision department, and whether its various types of parts and components will not cause pollution to the water quality in its certificate.

Pipeline pump is a kind of single-suction single-stage centrifugal pump, which belongs to a vertical structure. Because its import and export are on the same straight line, and the import and export caliber are the same, it resembles a section of pipe and can be installed at any position of the pipe, hence the name Pipeline Pump (also known as booster pump). Structural features: single-suction single-stage centrifugal pump, the same inlet and outlet, and the same line, and the center line of the shaft into a vertical, vertical pump.
