Abstract

Inventia se refera la constructia de masini hidraulice si poate fi utilizata in pompele centrifuge pentru echilibrarea sarcinii axiale a rotorului. Pompa centrifuga include un corp, in care sunt amplasati un arbore etansat fata de el si un impulsor al pompei centrifuge, montat pe arbore cu posibilitatea miscarii axiale, in discul caruia sunt executate orificii de scurgere, iar pe corp si pe impulsorul pompei centrifuge sunt executate proeminente circulare, amplasate una in fata alteia, care impart cavitatea dintre impulsor si corp in doua camere ce comunica. Pe corp, din ambele parti frontale ale lui, sunt fixate placi inelare de reazem, iar orificiile de scurgere executate in discul impulsorului pompei centrifuge de tip deschis sunt amplasate in fata camerei, care comunica prin ele cu zona de aspiratie a pompei. Arborele este etansat fata de corp prin intermediul unui cuzinet. Corpul, placile de reazem, impulsorul pompei centrifuge si cuzinetul sunt executate din material antifrictiune. ŕThe invention relates to the construction of hydraulic machines and can be used in centrifugal pumps for balancing the axial load of the rotor. The centrifugal pump includes a body, in which a sealed shaft is located opposite to it and a centrifugal pump impeller, mounted on the shaft with the possibility of axial movement, in which the discharge holes are executed, and on the body and on the centrifugal pump impeller are executed circular projections, located in front of each other, which divide the cavity between the impeller and the body in two communicating rooms. On the body, on both front sides of it, are fixed ring support plates, and the drain holes executed in the disc of the open type centrifugal pump impeller are located in front of the chamber, which communicates through them with the suction area of the pump. The shaft is sealed against the body by means of a bearing. The body, the support plates, the centrifugal pump impeller and the bearing are made of anti-friction material. à
