Definitions
- the invention relates to a single-stage liquid ring gas pump with an impeller that is overhung on a shaft and a housing with a suction and / or pressure chamber as well as suction and / or pressure ports on the side of the pump remote from the drive, in which the impeller has a continuous hub bore that is used for pressure /
- the suction chamber housing side is closed with a cover plate.
- a gland-like seal between the shaft and the impeller hub (FR-A 1254761), in which a made of plastically deformable Material of the existing sealing ring is deformed by the axial tightening of the glasses in such a way that it not only causes tightness, but also torque transmission.
- the glasses can be tightened using screws that interact either with the shaft or with the hub of the impeller. This arrangement does not allow axial adjustment of the impeller and also requires too much space in the axial direction.
- the invention is therefore based on the object of creating a liquid ring gas pump of the type mentioned, in which both the sealing of the hub bore and the axial adjustability of the impeller are made possible with simple means without any significant additional space requirement.
- a cover plate seals the hub bore from the suction or pressure chamber of the pump, is attached to the impeller hub by means of screws and is connected to the shaft via a screw for adjusting the axial position of the impeller.
- Fig. I shows in section a liquid ring gas pump which is flanged to an electric motor 1 as a block pump.
- the shaft passage through the pump housing is sealed by the mechanical seal 5.
- the control disk 6 is located on the side remote from the motor, and then the pump housing 7, which contains the running and pressure ports as well as the suction and pressure chamber and also the pump feet.
- the hub bore of the impeller passes through the entire impeller and on the side open towards the cover 7 it is sealed by a cover plate 8 which is firmly connected to the impeller hub by means of screws 9.
- Seals are provided on the contact surfaces 10, 11 and 12, in this case preferably liquid sealing compounds, which at these points prevent operating fluid or pumped medium from entering any space in the housing cover 7 into the hub bore 13 of the impeller 3 and here between the stub shaft and the impeller or can only cause corrosion on the shaft.
- the axial position of the impeller 3 can be fixed between the control disk 6 and the rear wall of the central body 2 by means of the screw 14. This means that the play between the impeller, control disc and rear wall of the center body can be adjusted exactly.
