Abstract
Przedmiotem zgłoszenia jest wirowa wielostopniowa pompa wysokociśnieniowa z bębnowo-tarczowym zespołem odciążenia naporu osiowego. Tarcza oporowa (5) od strony tarczy odciążającej (3) ma współosiowe obwodowe występy i współosiowe obwodowe rowki oraz tarcza odciążająca (3) od strony tarczy oporowej (5) ma współosiowe obwodowe występy i współosiowe obwodowe rowki, przy czym występy i rowki oporowej tarczy (5) oraz występy i rowki odciążającej tarczy (3) są wzajemnie osiowo wsunięte jedne w drugie kształtując wieloszczelinowy kanał (14). Wieloszczelinowe ukształtowanie kanału na tarczy oporowej i tarczy odciążającej powoduje zmniejszenie wysokości ciśnienia na wlocie do szczeliny osiowej między powierzchniami współpracującymi tarczy oporowej i tarczy odciążającej, co umożliwia powiększenie szerokości szczeliny osiowej przy małej stracie objętościowej.The subject of the application is a multistage high-pressure centrifugal pump with a drum-disk axial load relief unit. The thrust disc (5) on the unloading disc side (3) has coaxial circumferential protrusions and coaxial circumferential grooves, and the relieving disc (3) on the thrust disc side (5) has coaxial circumferential protrusions and coaxial circumferential grooves, the protrusions and grooves of the thrust disc ( 5) and the protrusions and grooves of the relieving disc (3) are axially inserted into each other to form a multi-slot channel (14). The multi-slot configuration of the channel on the thrust washer and the relieving disk reduces the pressure at the inlet to the axial gap between the counter surfaces of the thrust disk and the relieving disk, which allows the width of the axial gap to be increased with low volume loss.
