Rotorchamber profile of a liquid ring pump.

In liquid ring gas pumps of the type having a rotor rotatably mounted in a stationary housing for forming a quantity of pumping liquid into a recirculating ring inside the housing, fluid friction loss between the liquid and the housing is reduced by shaping the surface of the housing which is in contact with the liquid ring radially outside the rotor so as to minimize or at least substantially reduce the area of that surface.

LIQUID-RING VACUUM PUMP

On the outer surface of the rotor (1a) an annular channel is provided, which is interrupted by a transverse barrier (17). At the front of the barrier (17), in the rotational direction, a passage (18) connects to the pressure chamber (14), whilst at the roar of the barrier, a passage (19) connects to the suction chamber (13) so that air is alternately sucked (via passage 13) into the sickle shaped hollow space (9) which exists and forced out therefrom (via passage 14) as the rotor rotates. The pump is particularly suitable for liquids which are contaminated with particulate matter, as there are no narrow gaps. ...

The component may be that of a liquid ring pump component, rotary vane pump component or screw pump component. The pump component may also be at least one of a rotor component, stator component and a rotor shaft component. The use of alkoxysilane is used to reduce friction and therefore reduced power consumed during operation of a wet pump.

Liquid ring vacuum pump with cavitation regulation

A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage.

Mixtures of hydrophobic and hydrophilic ionic liquids and use thereof in liquid ring compressors

The present invention relates to mixtures comprising a hydrophilic and at least one hydrophobic ionic liquid, to the use thereof as a working fluid in liquid ring compressors and to a corresponding method.

Method for operating a heat pump and heat pump

Die Erfindung betrifft ein Verfahren zum Betrieb einer Wärmepumpe (1) mit den Schritten: – Kondensieren eines Fluids mittels wenigstens einer Kondensationseinrichtung (5); – Expandieren des Fluids mittels wenigstens einer Expansionseinrichtung (6); – Verdampfen des Fluids mittels wenigstens einer Verdampfungseinrichtung (2); und – Verdichten des Fluids mittels wenigstens einer Verdichtungseinrichtung (3). Beim Verdichten des Fluids wird eine ionische Flüssigkeit eingesetzt. Des Weiteren betrifft die Erfindung eine Wärmepumpe (1). The invention relates to a method for operating a heat pump (1), comprising the steps of: - condensing a fluid by means of at least one condensation device (5); - Expanding the fluid by means of at least one expansion device (6); - Evaporation of the fluid by means of at least one evaporation device (2); and - compression of the fluid by means of at least one compression device (3). An ionic liquid is used to compress the fluid. The invention further relates to a heat pump (1).

Method for operating a liquid ring compressor

The invention relates to a method of operating a liquid ring compressor having an impeller installed eccentrically in a compressor body, with gas being supplied to the liquid ring compressor on a suction side and gas being discharged from the liquid ring compressor on a pressure side. A liquid ring is generated in the liquid ring compressor on the inside of the compressor body by rotation of the impeller. Chambers are formed between blades of the impeller and the liquid ring and gas is drawn into these. The gas is compressed in the chambers which become smaller from the suction side to the pressure side as a result of the rotation of the eccentrically mounted impeller. The compressed gas is ejected on the pressure side. An ionic liquid is used as service liquid for generation of the liquid ring.
