Abstract

1379378 Liquid-ring vacuum pumps SIHI GmbH [trading as SIHI GmbH & CO KG] 9 April 1973 [8 April 1972] 17000/73 Heading F1C A vacuum pump unit comprises a liquid-ring vacuum pump, a drive motor, and a liquid circulating system including an elongated separator container and a radiator for the operating liquid of the pump, the container being arranged parallel to the pump and the motor, and the radiator being cooled by a fan driven by the motor. The unit shown comprises a base frame 1 supported on wheels 2 and carrying a two-stage liquid-ring vacuum pump 9 and its driving motor 10. The gas exhausted by the pump is delivered, together with entrained operating liquid, via a pipe 20 to an elongated separator tank 14, from which the separated gas is discharged at 21. Make-up liquid is conveyed to the tank 14 via a pipe 22, filter 23, solenoid valve 24, pipe 25 and non-return valve 26, any excess being discharged via a pipe 28. The solenoid valve 24 may be controlled by a switch sensing the level or temperature in the tank 14. Liquid is conveyed to the pump 9 via a pipe 27 branching from the pipe 25. The liquid is cooled by circulating it from the tank 14 to the pipe 25 via a pipe 29, a radiator 13 and a pipe 30, a cooling fan 12 for the radiator being driven by the motor 10. The fan 12, which also cools the pump 9 and motor 10, may be located at the other end of the unit. The tank 14 may be located laterally of the pump and motor, as shown, or above or below them.
