Problems with flow control of pipeline booster pumps
Thread Content
Suppose there is a water pump at the beginning of a pipeline, and for process requirements, another pump for increasing pressure is installed on the pipeline downstream of the water pump. If the rated flow rates of these two pumps are different, and given the limited buffer space in the pipeline, is it necessary to install a control valve at the outlet of the pressure-increasing pump to regulate the flow rate? Or, will the flow rate of the booster pump change automatically in response to the flow rate of the previous pump?
If a pipe has no branches, according to the principle of continuity of flow, the flow rate at any point within the pipe is equal. Pipeline flow is related to head as well as to resistance.
For the pump’s inverter, communication between inverters is necessary; isn’t it better to use a pressure transmitter to maintain a constant pressure?
