Are flexible connections installed at the inlet and outlet of the screw pump?
Thread Content
As shown in the diagram, it is a screw pump with fluid flow from top to bottom; there is a diameter change at each of the pump’s inlet and outlet. Using rubber flexible connectors for buffering and shock absorption would yield better results for achieving this diameter change. Since there is no vibration in the operating environment, I was wondering whether it would be feasible to use tees and flanges to make a direct connection. I would appreciate your advice!
A screw pump of this diameter doesn’t require a flexible connection, right????:)
May I ask under what circumstances it should be installed or not, and what is the basis for that?
It is recommended to visit sites with large equipment and low-viscosity oil stations, where such installations are not used. The ultimate goal is to create vibration without causing damage to the equipment. The basis for this is that there are such cases available as references. For reference.
The reliability of soft connections decreases. Something can be done with the pipe supports. The vibration of the screw pump itself is also limited
Soft connections are generally not used at the pump’s inlet and outlet; it is possible to weld the pipelines directly for size changes. Rubber soft connections are prone to breaking, which can lead to accidents, and high outlet pressure further exacerbates damage.
