[PDF]VARIABLE SPEED PUMPING - Energy.gov For a PD pump, the flow is proportional to speed, but the pressure can be inde- pendent of speed. Consequently, power and energy savings do not fall so quickly when speed is reduced. Sometimes it is necessary to operate PD pumps over a wider speed range than rotodynamic pumps, typically up to 10:1.文件大小: 1MB

VFD for Centrifugal Pumps - Variable Speed Drives Thus, this sort of duty cycle could provide energy savings by variable speed operation of the centrifugal pump. Fig. 2 Typical Centrifugal Pump Duty Cycle Centrifugal Pump Basics An understanding of the basic operating characteristics of centrifugal pumps is necessary to apply variable frequency drives to this particular application.
