| 107 | GEROTOR PUMP FOR LIQUID MEDIA | PCT/EP9706902 | 1997-12-10 | WO9826181A3 | 1998-11-05 | MOKESCH LUDWIG |
| The invention relates to a gerotor pump for aqueous viscous media which has preferably a two-piece pump housing consisting of pump chamber housing (3) and connection cover (29), and has, in the pump chamber housing, a pump chamber in the form of a circular cylindrical cavity (5) with a gerotor running carriage (9) accommodated therein. The gerotor running carriage (9) is rotationally driven by the motor shaft (11) of a driving motor (13) which is mounted immediately on the pump housing. The motor shaft (11) is encircled in the pump chamber housing (3) by a groove (68) which is directly connected to a cavity (70) in the suction area of the pump chamber (5), so as to be able to introduce leakage liquid via the groove (68) into the suction area of the chamber (5). In the connection cover (29) there is a channel (49) connecting the suction side with the delivery side, with a valve inside which, depending on the pressure on the delivery side, diverts excess carrying capacity to the suction side. The valve can alternatively be designed as a carrying capacity control valve. | ||||||
| 108 | METHOD AND APPARATUS FOR OPERATING A GAS TURBINE USING WET COMBUSTION | US15776821 | 2016-11-17 | US20180334957A1 | 2018-11-22 | Ralf KRIEGEL |
| The aim of the invention is to significantly increase the electrical efficiency or the proportion of the effective work of gas turbines, even in small gas turbines or microsize gas turbines having a simple design. According to the invention, the drawbacks of the prior art are overcome using wet combustion with oxygen, the oxygen being supplied via mixed-conducting ceramic membranes. The driving force needed for the oxygen to penetrate is created by lowering the partial pressure of the oxygen on the permeate side of the membrane module (5), and the energy required therefor is taken from the process energy produced in the gas turbine process. | ||||||

| A method of controlling a liquid ring pump in a pump system includes monitoring a vacuum pressure of the liquid ring pump using a pressure transmitter configured to transmit a vacuum pressure signal to a controller in operative communication with the liquid ring pump. The method also includes maintaining a predetermined vacuum pressure in the liquid ring pump under variable vacuum flow demand within the pump system in response to the vacuum pressure signal by controlling, via instructions from the controller, a parameter of the liquid ring pump based on a comparison of the vacuum pressure signal to the predetermined vacuum pressure by the controller. | ||||||

| Liquid ring pumps are used to pump a variety of fluid types. Corrosive fluids are easily handled by the work fluid but can cause corrosion of pumping mechanisms. The present invention provides a magnetically driven liquid ring pump with corrosion resistant pumping mechanisms which achieves a longer time between service intervals. | ||||||
| 112 | Liquid ring screw pump functional design | US14891545 | 2014-05-15 | US10030654B2 | 2018-07-24 | Ole Asgeir Svenheim |
| A liquid ring screw pump includes a housing with a suction inlet section and a pressure outlet section. Within the housing an Archimedes screw rotor is driven by a motor via a shaft. The inlet section and outlet section are each provided with connecting structure for suction and pressure piping respectively. The displacement CD of the screw rotor in relation to the center axis of the housing is determined by an equation based on the screw rotor radius, a minimum screw rotor core radius, and a variable k that is between 0.14 and 0.29. | ||||||
| 113 | IMPELLER-TYPE LIQUID RING COMPRESSOR | US15722402 | 2017-10-02 | US20180179894A1 | 2018-06-28 | Brian BLACKWELL |
| An impeller-type liquid ring compressor having a particular bearing configuration. Such a bearing arrangement may completely support the impeller as it rotates, eliminating many of the problems inherent in the prior art designs without changing the general overhung impeller design. This may allow the impeller-type liquid ring compressor to be easily retrofitted in existing use environments, such as, for example, oil and gas processing facilities, oil refineries, and petrochemical processing facilities. In some exemplary embodiments, a thrust bearing may be located on the front face of the impeller, or radial bearings may be disposed between the vanes of the impeller. A radial bearing and thrust bearing may further be disposed on the shaft side of the impeller close to the impeller itself. The compressor may be configured so that the process fluid carries heat away from each of these bearings. | ||||||

| A liquid-ring vacuum pump comprises a pump casing and a shaft eccentrically mounted in the pump casing. An impeller and a rotor of a drive motor are connected to the shaft. A disk cam is arranged parallel to the impeller. A first main bearing for the shaft is arranged between the impeller and the rotor of the drive motor, on the plane of the disk cam. The impeller is arranged between the first main bearing and a second main bearing. The arrangement of the bearings prevents the shaft from bending, thus allowing the leakage gap between the impeller and the disk cam to be kept small. | ||||||
| 115 | MOBILE SLUDGE EXHAUSTER AND METHOD | US14889854 | 2014-12-18 | US20160177952A1 | 2016-06-23 | Hans LARSEN |
| The invention relates to a mobile sludge exhauster including a tank for collection of sludge from a device that contains sludge and a vacuum system (8) for creation of suction. Sludge is sucked up and transported in a pipe unit to the tank. The vacuum system (8) includes a vacuum pump (1) and an air inlet pipe (3) for creation of an underpressure and a medium outlet pipe (4). The vacuum system (8) includes a pressure sensor (5) for measuring the absolute pressure P1 in the air inlet pipe (3) or in the vacuum pump (1) and a control and adjustment unit (7) for registering the measured pressure P1 and for correction of the pump's (1) rotational speed. A sludge exhauster is hereby achieved, which functions no matter the atmospheric pressure. | ||||||
| 116 | Liquid ring vacuum pump with cavitation regulation | US14364083 | 2012-12-12 | US09169838B2 | 2015-10-27 | Heiner Kösters; Matthias Tamm; Daniel Schütze |
| 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. | ||||||

| System for treating an effluent fluid stream from a process tool including a vacuum pump (16) for drawing an effluent stream from the process tool chamber, an abatement device (12) for treating the effluent stream and a liquid ring pump (14) for at least partially evacuating the abatement device (12). During use, the abatement device (12) converts one or more components of the effluent stream, for example F2 or a PFC, into one or more liquid-soluble a compounds, for example HF, that are less harmful to the environment. The liquid ring pump (14) receives the effluent stream and a liquid, and exhausts a solution of the liquid and the liquid-soluble component of the effluent stream. The liquid ring pump (14) thus operates as both a wet scrubber and an atmospheric vacuum pumping stage. | ||||||
| 119 | Ejector pump | US11883896 | 2006-01-12 | US08579596B2 | 2013-11-12 | Graeme Huntley |
| An ejector pump (100) includes a chamber having a gas mixing portion (108) and a diffuser portion (112). An inlet (10S) conveys a gas stream into the gas mixing portion, and an outlet (114) conveys the gas stream from the diffuser portion. To provide a motive fluid for the pump, a stream of plasma is ejected through a nozzle (116) into the gas mixing portion (108) of the chamber. Reactive species contained within the plasma stream react with a component of the gas stream to provide simultaneous pumping and abatement of the gas stream. | ||||||
