Throttling Process In Pumps at Curtis Donahue blog

Throttling Process In Pumps. Passive valves, or throttling valves, have a fixed position and do not change their loss coefficient in response to other. Control by throttling is used to influence the flow rate in a pump system by varying system resistance. The purpose is to defend the controlled variable against disturbances by adjusting the manipulated variable. The operating point moves to the left on the pump curve when the flow is decreased. How do throttling valves affect the system curve? There are three basic ways of controlling flow rate from centrifugal pumps. In pump systems, the manipulated variable is usually the flow of liquid. Throttling valves are one way of controlling flow rates, by throttling flow directly or in a bypass line. It is also the simplest way to shift. Throttling the discharge by closing a valve in the discharge line. Varying the speed of the pump. When the flow of a pump is regulated using a throttling valve, the system curve is changed. Sometimes a pressure drop occurs adiabatically when fluids flow through a restriction, such as an orifice, a valve, or a porous medium. In continuous processes, the conventional method for continuously controlling a pump is to throttle a control valve. Throttling control leads to high loss in the pump and in the valve when the system is running at a reduced flow rate.
