摘要： Single-stage liquid ring gas pump which can be flanged to a drive unit. The suction and delivery connections are disposed on a connection casing (3) which is to be connected to the drive unit. On the side of the connection casing remote from the drive are disposed a plate cam (4) and a working chamber casing (5) together with the impeller (14) rotating in the latter. The impeller sealingly cooperates on its open end face with the plate cam and on its largely closed end face (19) with an end wall (7) of the working chamber casing (5). The working chamber casing is in the form of a deep-drawn sheet metal part and has no medium connections. For the purpose of connection to the connection casing or the plate cam, it is provided with a radial connection flange (6). The transition from the cylindrical part to the connection flange (6) of the working chamber casing (5) is rounded on the inside such that the gap remaining between this rounding and the plate cam remains below a particular size. Its incircle should not be larger than 3.5% of the diameter of the impeller.

摘要： A liquid-ring pump according to the invention for use as a vacuum pump, e.g. for the aspiration of centrifugal pumps, and for use in the transport of fluids, e.g. mixtures of liquids and gases or solid particles, is of the type where the distance between the internal surface (17) of the pump housing and the rotor (10) varies. Seen in section, the surface is divided into two identical, reverse-image sectors, in relation to which the rotor (10) is disposed in a symmetrical manner. In the transition area between the two sectors the internal surface (17) is provided with a substantially flat surface (44) stretching tangentially in relation to the periphery of the rotor (10). Thereby cavitiation problems are reduced.

摘要： A two-stage liquid ring gas pump has a rotatable liner supported on a liquid bearing in the first stage housing. The liquid for the liner bearing is withdrawn from the second stage liquid ring and is therefore at a pressure which is high enough to support the liner for rotation without the need for any other component such as a liquid pump to pressurize it for that purpose.

摘要： The present invention relates a liquid-ring pump, in which the impeller (5) of the pump is rotatably arranged in the pump chamber formed by the pump housing (2), and the pump chamber is closed off by a disk cam 6 which has at least one inlet slit (8) and several output ports (10). Arranged between the disk cam (6) and a side shield (1) covering this disk cam is a suction chamber (7), connected to the inlet slit (8), and a pressure chamber (9), connected to the output ports. At least one of the output ports (10) is covered by a valve plate which may be moved away from this output port and be supported on a collector plate (12) affixed to the housing. The assembly of the valve plate is facilitated in that the collector plate (12) is connected to the side shield (1), and the valve plate (11) is guided by guide elements (14) penetrating through corresponding openings (15) in the valve plate (11), which openings are arranged between the collector plate (12) and the disk cam (6).

摘要： In a liquid-ring rotary compressor having a control element with a suction port, a pressure orifice, and a plurality of supplementary ports in front of the pressure orifice with respect to the direction of rotation of the compressor impeller, each supplementary port having a back-pressure valve, pressure losses are reduced by decreasing the flow area of the supplementary ports toward the pressure orifice so that the total flow area for the supplementary ports that are exposed by the back-pressure valves during the compression operation is roughly proportional, with respect to the prevailing nominal pressure condition of the compressor, to the gas mass existing in the vane chambers. Embodiments for flat and conical control elements is disclosed.

摘要： A fluid compressor comprises a casing containing liquid and having located within it a shaft driven radial impeller for pressurizing the liquid before it is fed to a further rotatable structure. By rotation of the impeller and the further rotatable structure, the high pressure liquid compresses a gas or vapor within the compressor casing and expels it from the casing through an outlet port therein. The high pressure liquid inlet end of the rotatable structure is partially shrouded by a shroud structure to restrict the input of high pressure liquid to part of the rotatable structure. The shroud structure has an opening therein which allows the high pressure liquid entering the rotatable structure to be depressurized and returned to the inlet end of the radial impeller after compressing the gas or vapor. By so doing, further gas or vapor for compression will be drawn into the compressor casing.
