Sentence examples for selecting pump from inspiring English sources

We realize all-optical switch effect by selecting pump light wavelength at the low Q mode and probe light wavelength at the other mode.

The chapter presents and demonstrates the procedure for selecting pumps and gas compressors and illustrates the theory and applications of pipeline design.

A step-by-step procedure for selecting pumps involves developing the calculations for the performance requirements completely and on the basis of the best- and worst-case assumptions for system dynamic headlosses, specifying materials that are suitable for the application, specifying the proper balance grade number, and deciding the number of pumps to be used and the type of pump.

Three solutions are introduced to improve the lack of fluid at some worst case point by using the current selected pump.

The best way to avoid hydraulic resonance is to calculate the expected resonance frequency while the piping system is being designed and make sure that it is well away from the vane-pass frequency of the selected pump.

It is found that as the pump characteristics will change with wear, erosion or fouling and the system characteristics will vary, a reliable control and protection system must be selected to continuously meet the objectives regardless of whether the selected pump is dynamic or positive displacement.

Thus, the head versus capacity performance curve of the selected pump can easily be plotted based on the performance of a single stage.

To ensure that the selected pump will meet all head or discharge pressure requirements, the TPH has to be calculated (Eq. 1), which is being directly affected by the continuous withdrawal of water that causes drawdown (Ebaid et al. 2013).

To kill a live closed-in gas well by bull-heading down the tubing, the selected pump rate should be high enough to ensure efficient displacement of the gas into the formation (i.e. to avoid the kill fluid bypassing the gas).

The basic principles that govern the calculations required to select pumps, valves and design installations are thus understood in fundamental terms.

All the selected pumps were China made.
