Abstract

Offenbart ist ein Verfahren zur Montage einer sauggedrosselten hydrostatischen Pumpe mit mehreren Pumpeinheiten, bei der der Saugventilöffnungsdruck jeder Pumpeinheit vor der Montage ins Pumpengehäuse geprüft und lediglich Pumpeinheiten oder Saugventileinheiten eingebaut werden, deren Saugventilöffnungsdrücke innerhalb eines vorbestimmten Druckintervalls liegen.

Figure 00000001
Disclosed is a method for assembling a suction-throttled hydrostatic pump with several pump units, in which the suction valve opening pressure of each pump unit is checked before installation in the pump housing and only pump units or suction valve units are installed whose suction valve opening pressures are within a predetermined pressure interval.
