PTFE lined fluorine centrifugal pump: fluorine lined centrifugal pump is generally lined with fluorine plastic centrifugal pump, fluorine lined centrifugal pump generally adopts the rear door structure, one person can easily carry out internal daily maintenance and parts replacement, without removing the pump import and export pipes, but the premise is that the installation process of fluorine lined centrifugal pump must understand the installation technology.

PTFE fluorine lined centrifugal pump is generally lined with fluorine plastic centrifugal pump, fluorine lined centrifugal pump generally adopts the rear door structure, one person can easily carry out internal daily maintenance and parts replacement, without removing the pump import and export pipes, but the premise is that the installation process of fluorine lined centrifugal pump to understand the key to installation technology where, the following talk about the fluorine lined centrifugal pump installation technology four must know, It may save you a lot of unnecessary trouble in the future.

1. The key to the installation technology of the fluorine lined centrifugal pump is to determine the installation height (that is, suction) of the fluorine lined centrifugal pump. This height refers to the vertical distance between the water surface and the center line of the fluorine-lined centrifugal pump impeller, which cannot be confused with the allowable suction vacuum height, the allowable suction vacuum height marked on the product manual or the nameplate of the fluorine-lined centrifugal pump refers to the vacuum value on the intake section of the fluorine-lined centrifugal pump, and is tested under 1 standard atmospheric pressure and the water temperature of 20 degrees Celsius. It does not consider the water flow condition after the matching of suction pipes. The installation height of the fluorine centrifugal pump should be allowed to absorb the vacuum height after deducting the suction pipe loss head, the remaining part of the value, it must overcome the actual terrain water absorption height. The installation height of the fluorine lined centrifugal pump cannot exceed the calculated value, otherwise, the fluorine lined centrifugal pump will not be able to pump water.

2. The size of the influence of the calculated value is the resistance loss head of the water suction pipe, so it is appropriate to use the shortest pipe layout, and install as few elbows and other accessories as possible, and consider appropriately matching some large caliber water pipes to reduce the pipe flow rate.

3. It should be pointed out that in the chemical pump, when the elevation and water temperature of the installation site of the fluorine lined centrifugal pump are different from the test conditions, such as the local elevation of 300 meters or the water temperature of the pumped water exceeds 20 degrees Celsius, the calculated value should be corrected. That is, the atmospheric pressure at different altitudes and the saturated steam pressure at water temperatures above 20 degrees Celsius. However, when the water temperature is below 20 degrees Celsius, the saturated steam pressure is negligible.

4. From the pipeline installation technology, the suction pipe requires strict sealing, no air leakage, water leakage, otherwise it will destroy the vacuum at the inlet of the fluorine-lined centrifugal pump, so that the water output of the fluorine-lined centrifugal pump is reduced, and even the water cannot be pumped in serious cases. Therefore, it is necessary to carefully do the interface work of the pipeline to ensure the construction quality of the pipeline connection.
