COMBINED BOILER FEED AND CONDENSATE PUMP |
摘要 |
Docket No. 1083-IR-CA A boiler feed pump including an elongate casing adapted to be interconnected in a pipeline and a variable speed electrical motor driving an axially extending shaft, which drives a condensate inducer pump and a multiple stage centrifugal pump, all of which are housed within the casing. The inducer pump comprises a series of axially spaced rotating annular disks which the condensate flows between. The centrifugal pump receives the condensate from the inducer pump and pumps it to a higher pressure suitable for feeding a boiler. The motor can operate at a variable speed to handle various flow demands. The motor also serves as a thrust balancing device for the multiple stage centrifugal pump. |
