Schneckenpumpe
EMI1.1
<Desc/Clms Page number 2>
nung ausführlicher erläutert : Es zeigen Fig. 1 in einem Axialschnitt eine erfindungsgemässe Schneckenpumpe, Fig. 2 einen Schnitt in Richtung A-A durch den Gegenstand nach Fig. 1.
Die in den Figuren dargestellte Schneckenpumpe besteht in ihrem grundsätzlichen Aufbau aus dem Rotor l, derausStahl in Form einer eingängigen Schnecke ausgeführt ist, und dem Stator 2, der als zweigängige Schnecke ausgeführt und aus elastischem Material, nämlich Naturgummi oder synthetischem Gummi, besteht. Läufer 1und Stator 2 arbeiten dabei so zusammen, dass ein stetiger dichter Abschluss erzielt wird, der bei der Rotation sich entlang des Stators 2 verschiebt, wodurch die Pumpwirkung erreicht wird. Der Antrieb des Rotors 1 erfolgt über die Antriebswelle 3, was im einzelnen nicht der näheren Be- schreibung bedarf. Im übrigen mündet in das Pumpengehäuse 4 der Saugstutzen 5 ein, während der Druckstutzen 6 hinter dem Rotor 1 an das Pumpengehäuse 4 angeschlossen ist.
Die einzelnen Gehäuseteile sind mittels Schraubenbolzen 7 miteinander verbunden.
Das Gehäuse 4 für die mehrgängige elastische Statorschnecke 2 besitzt radial verstellbare Druckstücke 8, gegen welche die Statorschnecke 2 abgestützt ist. Durch Verstellung der Druckstücke 8 in radialer Richtung ist somit die Schnecke nachstellbar. Die Druckstücke selbst sind mittels Stiften 9 im Pumpengehäuse 4 geführt, und ihrerseits durch eine Schelle 10 einstellbar, die auf die Stifte 9 gelegtund anziehbar ist. Die Stifte 9 sind dabei mit der Schelle 10 selbstverständlich nicht starr verbunden.

Screw pump
EMI1.1
<Desc / Clms Page number 2>
The following is explained in more detail: FIG. 1 shows an axial section of a screw pump according to the invention, FIG. 2 shows a section in direction A-A through the object according to FIG. 1.
The screw pump shown in the figures consists in its basic structure of the rotor 1, which is made of steel in the form of a single-flighted worm, and the stator 2, which is constructed as a double-flighted worm and is made of elastic material, namely natural rubber or synthetic rubber. The rotor 1 and stator 2 work together in such a way that a continuous, tight seal is achieved which, when rotated, moves along the stator 2, whereby the pumping effect is achieved. The rotor 1 is driven via the drive shaft 3, which does not need to be described in detail in detail. In addition, the suction connection 5 opens into the pump housing 4, while the pressure connection 6 is connected to the pump housing 4 behind the rotor 1.
The individual housing parts are connected to one another by means of screw bolts 7.
The housing 4 for the multi-start elastic stator worm 2 has radially adjustable pressure pieces 8 against which the stator worm 2 is supported. By adjusting the pressure pieces 8 in the radial direction, the screw can thus be readjusted. The pressure pieces themselves are guided in the pump housing 4 by means of pins 9 and are in turn adjustable by means of a clamp 10 which is placed on the pins 9 and can be tightened. The pins 9 are of course not rigidly connected to the clamp 10.
