Embodiment Construction

[0021] figure 1 The liquid ring vacuum pump in includes a housing 14 with a base 15 . A shaft 19 is mounted in the housing 14, the shaft 19 extending transversely through the housing 14 from the left end to the right end, the shaft 19 supports the rotor 20 of the drive motor of the pump on one side and the impeller 21 on the other side, through which 21 Transport the gas to be delivered.

[0022] The housing 14 consists of three housing parts 16, 17, 18 in the axial direction, the impeller 21 is accommodated in figure 1 In the housing part 18 shown on the left, and the drive motor is accommodated in the housing part 16 shown on the right. The drive motor includes a rotor 20 connected to the shaft 19 and a stator 24 connected to the housing part 16 . Electrical power is supplied to the drive motor via a power supply 25 causing the shaft 19 to be arranged to rotate with the impeller 21 . The medium to be conveyed is conveyed by the rotation of the impeller 21, more details w...

Abstract

The invention relates to a liquid ring vacuum pump, comprising a pump housing (18) and a shaft (19) eccentrically mounted in the pump housing (18). The impeller (21) and the rotor (20) of the drive motors (20, 24) are connected to the shaft (19). The disc-shaped cam (22) is arranged in parallel with the impeller (21). According to the invention, the first main bearing (23) for the shaft (19) is arranged between the impeller (21) and the rotor (20) of the drive motor on the plane of the disc cam (22). The impeller (21) is arranged between the first main bearing (23) and the second main bearing (26). The arrangement of the bearings according to the invention prevents the shaft (19) from bending, allowing the leakage gap between the impeller (21) and the disc cam (22) to be kept small.

Description

technical field [0001] The invention relates to a liquid ring vacuum pump with a shaft mounted eccentrically in the pump housing. The impeller and the rotor of the drive motor are connected to the shaft. The control disc is arranged parallel to the impeller. Background technique [0002] This type of pump can be used to evacuate containers or other enclosed spaces. The inlet opening of the pump is connected to the space to be evacuated, the gas contained in said space is sucked into the inlet opening, compressed in the pump and expelled again through the outlet opening. [0003] In a liquid ring vacuum pump, the liquid ring is maintained in motion by the impeller, causing the chamber between the vanes of the impeller to be closed by the liquid ring. Due to the eccentric mounting of the impeller in the pump housing, the liquid ring penetrates into the chamber to varying degrees depending on the angular position of the impeller, thus acting as a piston that changes the volu...
