Abstract
Przedmiotem wynalazku jest ulepszenie wirowej pompy wielostopniowej średniociśnieniowej według patentu PL 217975. Tylna tarcza (1) ostatniego wirnika (2) pompy od strony zewnętrznej ma współosiowe obwodowe występy (3) i obwodowe rowki (4), a tłoczny kadłub pompy od strony tarczy (1) wirnika (2) zamknięty jest czołową tarczą (5) z zewnętrznymi obwodowymi występami (3) i obwodowymi rowkami (4), a co najmniej na jednym obwodowym występie (3) bądź obwodowym rowku (4) tylnej tarczy (1) wirnika (2) i/lub czołowej tarczy (5) kadłuba tłocznego ma obwodowe wgłębienie (6), dzielące określoną szczelinę (7) na dwie części.The subject of the invention is an improvement of a multi-stage medium-pressure rotary pump according to patent PL 217975. The rear disc (1) of the last impeller (2) of the pump on the outer side has coaxial circumferential projections (3) and circumferential grooves (4), and the pump discharge housing on the side of the impeller (2) disc (1) is closed with a front disc (5) with external circumferential projections (3) and circumferential grooves (4), and at least one circumferential projection (3) or circumferential groove (4) of the rear disc (1) of the impeller (2) and/or the front disc (5) of the discharge housing has a circumferential recess (6) dividing a defined gap (7) into two parts.
