| Low-cost apparatus is described for treating an effluent fluid stream from a process tool. In one embodiment, the apparatus comprises an abatement device (12) 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. | ||||||

| Liquid ring pumps are used to pump a variety of fluid types. The present invention provides a two stage liquid ring pump through which an exhaust gas comprising compounds to be destroyed is passed. The exhaust gas passes through the first stage to a gas abatement device, following which it is passed back to the second stage of the liquid ring pump for removal of the compounds formed in said abatement device. The stages of the liquid ring pump may be adjustable. | ||||||

| A microfluidic pump comprising a cylindrical chamber, transfer ports comprising an inlet port and an outlet port positioned on the cylindrical chamber, a magnet member attached outside the cylindrical chamber, a magnetic piston in sliding communication with inner walls of the cylindrical chamber, a magnetic material, and a valve member. The magnetic material self assembles to form a seal plug separating the inlet and outlet port, where the seal plug forms a link between the magnet member and the magnetic piston to rotate the magnetic piston along the inner wall of the cylindrical chamber, where a working fluid suctioned within the cylindrical chamber is discharged at the outlet port during a movement of the magnetic piston from the inlet to outlet port. The valve member positioned at the outlet port prevents the backflow of the working fluid towards the inlet port after the magnetic piston rotates past the outlet port. | ||||||
| 48 | Liquid Ring Vacuum Pump with Cavitation Regulation | US14364083 | 2012-12-12 | US20140377084A1 | 2014-12-25 | 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. | ||||||
| 49 | Ejector Pump | US11883896 | 2006-01-12 | US20120148421A1 | 2012-06-14 | Graeme Huntley |
| An ejector pump (100) comprises 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. | ||||||

| 52 | VACUUM PUMP WITH WEAR ADJUSTMENT | US11625171 | 2007-01-19 | US20080175723A1 | 2008-07-24 | David Muhs |
| A vacuum pump having components that are subject to wear may be adjusted to compensate for the wear. In some instances, a vacuum pump may include a housing and an impeller disposed at least partially within the housing. A gap between the housing and the impeller may be adjustable to compensate for wear. In some cases, the housing may include a ring that may be moved to adjust a tolerance (or gap) between the ring and the impeller. In some instances, the ring may be rotated to adjust this gap. In other instances, the ring may be translated to adjust the tolerance. | ||||||
| 53 | Closed oil liquid ring gas compression system with a suction injection port | US09974496 | 2001-10-10 | USRE38434E1 | 2004-02-24 | Gary Jennings |
| A gas compressor system draws and compresses gas from a well, wherein the gas has entrained liquid and vapor. The apparatus has a scrubber vessel for receiving the gas and separating at least a portion of the liquid. A storage vessel integral with the scrubber stores seal liquid. The seal liquid is injected into the gas before a single stage liquid ring pump which uses the seal liquid to compress the gas. The compressed gas along with entrained seal liquid is routed to a separator vessel having a coalescing filter. The entrained seal liquid is separated from the gas and routed back to the storage vessel. | ||||||

| To provide a gas compressor in which a gas leakage from compression chambers is suppressed to thereby make it possible to enhance compressor characteristics such as a volumetric efficiency. A seal member is interposed between a cylinder of a gas compressor and two side blocks for sealing both end faces of the cylinder, and the seal member is arranged at a position for separating inside and outside of the cylinder so as to surround an opening of a hollow portion of the cylinder. The end face of the cylinder is brought into intimate contact with the end surface of a rear side block or a front side block. Then, the confronting surfaces of the two members are brought into intimate contact with each other to form a close contact portion. | ||||||

| A centrifuge gas compressor for compressing gases to higher pressure states having a housing hollow interior, inside the hollow interior is a distributor and a rotating disc; the distributor is used for channeling gas and liquids into the rotating disc. The rotating disc contains a multiplicity of compression conduits extending perpendicular from a rotating axis of said disc whereby gas and liquids are channeled through. The spinning disc creates centrifugal force on the gas and liquid mixture and forces the mixtures towards smaller exit openings thereby compressing the gas in the process. The compressed gas then exits the spinning disc at a perimeter opening whereby the high-pressure gas can be used for its intended purpose. | ||||||

| 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. | ||||||

| 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. | ||||||
