Adjusting the flow can save energy
Jul 12, 2018

The characteristic curve of stainless steel centrifugal pump and pipeline system analyzes several main ways of centrifugal pump flow regulation: outlet valve regulation, pump shift regulation and pump series and parallel regulation. The energy consumption loss of the two methods of outlet valve regulation and pump speed regulation is analyzed by the characteristic curve, and the comparison is made. It is pointed out that the variable speed regulation flow of the centrifugal pump can save energy and save energy by adjusting the flow rate with the outlet valve. It is related to the size of the flow change. In practical applications, attention should be paid to the range of shift regulation to better apply the centrifugal pump shift regulation.
