How to eliminate blind plate force when water pump installs rubber joint?

Henan Shunying New Energy Co.,Ltd. Official website will introduce information for you: How to eliminate blind plate force when install rubber joint for water pump , if you can not eliminate blind plate force, then choose anti-pull rubber joints to eliminate blind plate force which do not make rubber joints damaged.

Since the pump end is a fixed base, it can be regarded as a fixed end, and the pipeline will not be deviated. Therefore, all the axial thrust generated by blind plate force is diverted to the main pipe at the pump outlet, and the main pipe will be deviated. When the offset is too large, it may appear that the flexible rubber joint is pulled out from the flange.

When the water pump adopts the straight line piping (Buried main pipe laying), the water pump piping is shown.;

The inlet and outlet pipes are the same; DN500 mm, water supply pressure 0.55 MPa, It can explain this problem. When the pipe diameter is larger or the water pressure is higher, the blind plate force generated by the outlet pressure will be larger, which will generate a great thrust to the pump end and the buried outlet main pipe. Due to the buried outlet main pipe laying, the soil resistance makes the pipe cannot ,be deviated.All thrust is deflected to the pump .Therefore, the foundation bolts and pump are easily damaged.

When the water pump adopts vertical pipe, the flexible rubber joint installed on the pipe will expand and push the pipe upward under the blind plate force generated by the water pressure. When the water pressure is too large, the flexible rubber joint may be pulled out from the flange.

Analysis of blind plate force under different water pressure: The blind plate force produced by the blind end of the pump outlet pipe. It can be seen that with the increase of pipe diameter and water pressure, the blind plate force produced by water flow also increases. Generally, when the pipe diameter is not less than 150 mm, the pipe with flexible rubber joints should be installed with anti-pull device or fixed pipe rack to eliminate the blind plate force generated by water pressure.

The blind flange force of water pump outlet pipe response in water piping design, when the system needs to install a flexible rubber joint, piping system should be analyzed whether can eliminate the influence of the blind flange force itself, if can not be eliminated , it should be chosen with anti pulled off in a flexible rubber joint or setting fixed tube frame, in order to eliminate the blind plate force acting on the pipeline caused by the deviation.
