Description

Selbsttätig ein- und ausschaltbare Vakuumpumpe für Kreiselpumpenanlagen. In größeren Kreiselpumpenanlagen sind in der Regel Vakuumpumpen erforderlich, welche die Kreiselpumpen vor der Inbetriebsetzung entlüften bzw. mit Wasser auffüllen. Diese Vakuumpumpen sind in -der Regel nur für vorübergehenden Betrieb gebaut und müssen ausgeschaltet werden, sobald die Kreiselpumpen- entlüftet sind. Um nun die 'Pumpenanlagen selbsttätig betreiben zu können, ist auch für die Vakuumpumpe eine selbsttätige Ein- und Ausschaltvorrichtung erforderlich. Bisher wurden die kleinen Antriebsmotore der Vakuumpumpen entweder durch Schwimmerschalter, Vakuumschalter, Druckschalter o..dgl. in und außer Betrieb gesetzt. Derartige Schaltvorrichtungen haben jedoch den Nachteil, daß sie nicht rechtzeitig ,die Vakuumpum e wieder in Betrieb setzen, wenn während ödes Betriebes der großen Kreiselpumpe Luft in, letztere gelangt, so daß sie versagen muß.Vacuum pump for centrifugal pump systems that can be switched on and off automatically. In larger centrifugal pump systems, vacuum pumps are usually required, which vent the centrifugal pumps or fill them up with water before commissioning. These vacuum pumps are usually only built for temporary operation and must be switched off as soon as the centrifugal pumps are vented. To now the 'Being able to operate pump systems automatically is also one of the things for the vacuum pump automatic switch-on and switch-off device required. So far, the little ones Drive motors of the vacuum pumps either by float switches, vacuum switches, Pressure switch or the like put in and out of service. Such switching devices however, have the disadvantage that they do not get the vacuum pump back in in time Start operation if air enters the large centrifugal pump while the pump is idle so that it must fail.

Nach vorliegender Erfindung wird' die Ein-und Ausschaltung .der Vakuumpumpe durch die Strömung des Wassers betätigt. Die Vakuumpumpe bleibt also eingeschaltet, solange das Wasser in den Saug- oder Druckleitungen der Kreiselpumpe nicht in Strömung ist. Ist aber die Kreiselpumpe vollkommen entlüftet, so diaß sie Wasser fördern kann, so tritt eine Wasserströmung in den Rohrleitungen ein. Die Vakuumpumpe wird selbsttätig ausgeschaltet. Das Ein- und Ausschalten der Vakuumpumpe A kann, wie aus Abb. i ersichtlich, durch eine Rückschlagklappe B, durch eine Drosselklappe C oder durch einen Wasserstromschalter D erfolgen. Diese Betätigungsmittel können sowohl in die Saugleitung wie in die Druckleitung der Kreiselpumpe eingebaut werden.According to the present invention, the switching on and off .the vacuum pump actuated by the flow of water. The vacuum pump remains switched on, as long as the water in the suction or pressure lines of the centrifugal pump is not flowing is. But if the centrifugal pump is completely vented, it will deliver water can, a flow of water occurs in the pipelines. The vacuum pump will switched off automatically. Switching the vacuum pump A on and off can, like can be seen from Fig. i, through a non-return valve B, through a throttle valve C or by a water flow switch D. These actuators can be installed in both the suction line and the pressure line of the centrifugal pump.

Die Rückschlagklappe B, Drosselklappe C oder der Wasserstromschalter D werden in ihrer Einschaltstellung durch Feder, Gegengewicht o. dgl. gehalten, derart, daß erst ein starker Wasserstrom die Ausschaltung bewirken kann. Es ist .dies wichtig, damit nicht bei der geringsten Wasserbewegung in den Rohrleitungen schon das Ausschalten der Vakuumpumpe geschieht, sondern erst dann, wenn die Kreiselpumpe vollkommen entlüftet ist und ordnungsgemäß zu fördern beginnt. Die Schaltvorrichtungen können sowohl den elektrischen Strom des Antriebsmotors der Vakuumpumpe aus- und einschalten wie auch eine ausrückbare Kupplung E (Abb. a) betätigen. In letztgenanntem Falle ist ein besonderer Antriebsmotor für die Vakuumpumpe nicht erforderlich, vielmehr wird letztere dann mit der Welle der Kreiselpumpe gekuppelt.The check valve B, throttle valve C or the water flow switch D are held in their switched-on position by a spring, counterweight or the like, in such a way that only a strong flow of water can cause the switch-off. It is . This is important so that not at the slightest movement of water in the pipelines the vacuum pump is switched off, but only when the centrifugal pump is completely vented and begins to pump properly. The switching devices can turn off and off both the electric current of the drive motor of the vacuum pump switch on as well as actuate a disengageable clutch E (Fig. a). In the latter Case, a special drive motor for the vacuum pump is not required, rather the latter is then coupled to the shaft of the centrifugal pump.
