KONSTANTNOG PROTOKA ZA SERVOUPRAVLJANJE

1 PUPE OPIS Ova familija pumpi primenjuje se u zatvorenim hidrauličkim sistemima servoupravljanja na motornim vozilima, ali može da ima primenu i u drugim hidrauličkim sistemima. Ove pumpe se pokreću pogonskim motorom preko odgovarajuće spojnice, zupčanika, remenice ili vratila kompresora. Kod pogona pumpe obratiti pažnju na sledeće: - Kod pogona preko remenice ili zupčanika treba imati u vidu da je mogućnost nošenja radijalnih sila ograničena, pa je potrebno konsultovati proizvođača. - Kod pogona preko kompresora prenos obrtnog momenta sa vratila kompresora na vratilo pumpe treba da se ostvaruje spojnicom koja dozvoljava vrlo mala odstupanja u saosnosti. - Obrtanje pumpe sme da bude samo u naznačenom smeru. - Pumpu ugraditi tako da joj usisni vod bude ispod nivoa rezervoara iz koga usisava radnu tečnost, a vod za usisavanje je preporučljivo da bude što kraći i sa što manje krivina. psolutni pritisak u usisnom vodu sme da bude najmanje 0,85 bar pri temperaturi od 50 C, s tim da se ne 2 prekorači viskozitet od 27 mm / s. - ko se koristi pumpa bez ugrađenog ventila za ograničenje pritiska, isti treba predvideti posebno ili ga ugraditi u hidraulički servoupravljač ( u hidrauličkom sistemu ne smeju da se nađu dva ventila sigurnosti ). PUPS DESCRIPTION: This family of pumps is mainly applied to closed-loop hydraulic servo steering system on motor vehicles, but it can also be applied to other hydraulic system. These pumps are put into operation by means of drive motor via corresponding coupling, gear, pulley of compressor shaft. Regarding pump drive, special attention should be paid to the following: - In case of pulley or gear drive always bear in mind that the capability to withstand radial forces is limited, so it is necessary to consult the manufacturer. - In case of drive via compressor, transmission of the torque from the compressor shaft to the pump shaft should be effected by a coupling which allows only for small deviations from axial alignment. - The pump is allowed to rotate only in specified direction. - The pump is to be mounted in such a way that its suction line lies below the level of the tank from which working fluid is "sucked in", and suction line is recommended to be as short as possible, the fewer curves the better. The absolute permissible pressure within the suction line should be min. 0,85 bar at the temperature of 2 50 C, and the viscosity of 27 mm /s is not to be exceeded. - In case the pump without pressure-relief valve is used, the valve is to be provided separately or otherwise installed within hydraulic servo steering gear (there should not be two safety valves within a single hydraulic system). -1
