Questions related to the RO pressure stabilization pump, thank you
Thread Content
The RO pressure-stabilizing pump is used in water purifiers, but it is actually a type of diaphragm pump. I would like to know how this pump manages to stabilize pressure When testing the performance of a pump, there are significant fluctuations in pressure when the pressure gauge is connected directly. How can one ensure consistent inlet and outlet pressures? Also, when testing flow rate at specified inlet and outlet pressures, can the inlet pressure be adjusted using a valve? Do we need to consider the issues of dynamic pressure and static pressure?
Diaphragm pump outlets are typically equipped with pulsation dampers, which serve to reduce pressure fluctuations and also help stabilize the pressure. Positive displacement pumps are generally regulated by stroke adjustment or speed adjustment, as well as bypass adjustment, without inlet throttling regulation. Positive displacement pumps generally do not take into account dynamic pressure.
