Sentence examples for frequency speed from inspiring English sources

When installing a pump with an optimal characteristic curve, it is not necessary to increase the number of frequency speed drives.

Wind tunnel tests were performed to measure the lift and thrust of the mechanical membrane flapping wing under different frequency, speed, and angle of attack.

Etched into tiny skeletal structures that would be impossible to form with metal, it becomes the featherweight heart of a mechanism that can run at a far higher frequency (speed), which means greater accuracy.

The application of distributed variable frequency speed pump (DVFSP) in the district heating network has been considered as a technology improvement that has a potential in saving energy compared to the conventional central circulating pump (CCCP) district heating system (DHS).

Explanatory variables used included service level, frequency, speed, stop spacing, share of segregated right of way, vehicle accessibility, employment and residential density, car ownership levels and BRT infrastructure quality.

The purpose of this study is to develop a decision support tool to obtain the theoretical characteristic and efficiency curves of the pumps, the number of pumps, and the number of frequency speed drives that minimize the total cost (investment and operation costs) for a specific pumping station demand (design flow, pressure head, and frequency of the discharges).

In this paper a new district heating network with distributed variable-frequency speed pumps (DVFSP) is presented and analyzed.

The distributed variable-frequency speed pump (DVFSP) district heating system is not only to set circulating pump in the heat source, but also to set booster pumps in the heating pipeline network.

Compared with the traditional centralized power heat supply system, the distributed variable-frequency speed pump district heating system has more advantages in solving the hydraulic imbalances and improving the energy-saving rate of the heating system.
