How can I control a pump’s main outlet pipe, which needs to be divided into 10 branches, so that each branch maintains the same flow rate and pressure?
Thread Content
How should flow and pressure be controlled in 10 branches derived from the outlet main pipe of a pump (DN350, 420 m3/h), so that each branch has the same flow rate and pressure? The key is also to save as much money as possible. Do anyone have any good suggestions? ?
Control the main pipe pressure and flow rate? Does each responsible area still have traffic? The description is not particularly clear.
A valve is installed on each circuit for manual adjustment; it is impossible to keep both flow rate and pressure constant. Only the flow rate can be controlled, and adjustments must be made based on feedback from the actual flow rate (either the flow rate itself or the total amount of fluid that passes per unit time)
Perhaps the original poster could take a look at the hot water systems in universities – there is one main pipe from which many branch pipes emerge, and the flow rate at each faucet is more or less the same
It seems to be a recirculating water system; as long as the pipe diameters and lengths are similar, the flow rate should not differ much.
Flow rate is controlled by valves, so there will be differences in pressure After all, the voltage drop across each branch is not the same!
It depends on the pressure at the outlet of the pipe. According to Bernoulli’s equation, when the inlet and outlet pressures are constant, as well as the pipe diameter, the flow rate remains constant
Just install control valves on the direct branches; adjust them to the desired level
It’s fine as long as there’s no branch pipe with a manual valve; as for pressure, it can be adjusted using a manual valve, and sometimes it’s determined by the pressure of the equipment at the end of the pipe.
