Experts: What are the effects if the flow rate and head of a self-priming pump increase, while the outlet pipe remains unchanged? Thank you!
The pressure at the pump outlet increases, and the fluid flow rate increases as well.
It has no significant impact; it depends on whether the motor is sufficient and whether there will be an overload
Does it mean replacing it with a new self-priming pump that has a higher flow rate and head for use in the original pipeline?
That is, the outlet pressure has increased; let’s see if the original pipe’s pressure rating is sufficient
As the flow rate increases while the diameter of the pipe remains unchanged, the flow velocity rises, leading to more severe erosion of the pipe and its fittings. Turbulence also increases, resulting in higher hydraulic losses. Additionally, as the flow velocity increases, the stress at the bends in the pipe rises, so it is necessary to strengthen the fixation of the pipe and its fittings. As the head increases, it becomes necessary to determine whether the pressure rating of the pipelines and their accessories is sufficient, whether the connection structures at various joints can still function properly, and whether the reliability of the static seals decreases, thereby increasing the likelihood of leaks.
