Determination of the operating point of pumps in parallel plays a vital important role in design of pumping station. 水泵并联运行的工况点确定在泵站设计中占据着极其重要的地位。 www.ceps.com.tw 2. Using Numerical Method to Calculate Operating Points of Centrifugal Pumps in Parallel 离心泵并联运行工...
The series of the pump The series of pumps mainly solve the problem of insufficient head, after the series of pumps, its flow unchanged, head is the sum of the two pumps.In practice, in order to avoid the water inflow of the downstream pump to the upstream pump is not enough, the ...
An additional aspect is a method of using an open-loop response to deal with large transients threatening to force a pump into an operating region that might result in damage or destruction.Saul MirskyKrishnan Narayanan
The Series/Parallel Pumps Bench, "PBSPB", is designed to demonstrate the operational advantages of parallel or series operation, depending on the required duty.
feed flow by reducing the increasing rate of drive power source output when the feed flow becomes positive from approximately zero when a pump is started newly, in an operating method in which the number of multiple operating pumps connected in parallel with each other is increased or decreased....

This paper presents an optimization framework based on dynamic programming mathematic tool suitable to be implemented in programmable logic controllers to improve the automated control of parallel pumping loops aiming at energy conservation. The paper also contributes with simple methods to derive system cu...
I've a spreadsheet for plotting pump curves on one chart but the problem is in adding the abscissa (x, flow) values for the same ordinate (y, head) values. The two curves are not input with common y-values. The fastest way seems to be to plot out the two pump curves on one ...
