245 | ROTARY VANE PUMP STATOR | EP15903690.4 | 2015-09-08 | EP3269981A1 | 2018-01-17 | Mikheev, Alexandr Vasilievich |
The present invention relates to hydraulic machinery engineering, more specifically to stators of rotary vane-type pumps intended for pumping-over viscous, plastic masses and other fluids and multiphase mixtures lacking unctuous properties, but rich in mechanical impurities and/or having high viscosity, particularly such as stratum fluids of oil deposits, and may be applied in food-processing, chemical, petrochemical and other branches of industry. A technical result to be achieved in implementation of the present invention lies in reduction of transfer area of a pumped fluid having high viscosity and high content of abrasive particles and gas, which leads to raising reliability of stator, increase of its service life, and enhancement of functional capabilities of the pump using such stator. Said technical result is achieved by a stator of a rotary vane-type pump being configured as shells connected by bridges; wherein each of the shells comprises a hollow cylinder formed by two pairs of opposed concentric annular sectors, radii of curvature of each pair being different from each other, and four portions smoothly connecting said sectors; wherein said bridges are joined with the annular sectors of the shells, and have radii of curvature in cross-section corresponding to the radii of curvature of the annular sectors of the shells, and wherein the bridges have a width selected so as to minimize an area of a fluid transfer. |

248 | TWIN-SCREW LIQUID PUMP | EP10859796 | 2010-11-30 | EP2642125A4 | 2016-11-16 | TANG YAN |
A double-screw liquid pump is provided, which is applicable to an Organic Rankin Cycle (ORC). The double-screw liquid pump includes a semi-sealed or fully sealed shell, and the shell includes a first cavity and a second cavity isolated from each other. A motor is disposed in the first cavity, and a main body part of a double-screw is disposed in the second cavity. At least one rotor of the double-screw is fixedly connected to a rotor of the motor, and the double-screw rotates through driving of the motor. A liquid refrigerant injection inlet and a refrigerant outlet are disposed on the first cavity, and the motor is cooled through evaporation of a liquid refrigerant; a liquid inlet and a liquid outlet are disposed on the second cavity. In the double-screw liquid pump applied to the ORC provided in the present invention, since a resistance torque of the female rotor is very small, the liquid pump does not wear even when the liquid viscosity is very low, contributing to good reliability, and thereby improving power generation efficiency of the ORC. In addition, the semi-sealed or fully sealed shell can effectively prevent leakage of the refrigerant. | ||||||

256 | ENHANCEMENT OF SURFACE-ACTIVE SOLID-PHASE HETEROGENEOUS CATALYSTS | EP06800837.4 | 2006-08-03 | EP1919617A2 | 2008-05-14 | COTTER, Mitchell, A. |
Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration. | ||||||

The present invention pertains to a rotary piston regulating device (1) intended for measuring flowable or pourable material, either powdery or granulous. In a cylinder casing (4), a rotary piston is arranged so as to form, in the area of the peripheral surface (18), so tight an area in relation to the cylinder inner surface (6) that, when the cylinder is rotating for each cycle, a working chamber (22) is defined - extending from an inlet area (8) - to receive a certain volume of said material. In order for the volume fed to the working chamber (22) to be modulated, a regulating valve (6) radially adjustable relative to the cylinder casing (4) causes the opening (W) of a slot (40) situated between the rotary piston (14) and the piston-oriented valve end (36) to vary. For intermittent adjustment of the feed slot (40) in each cycle, the valve (36) is radially actuated in both directions by means of a control member (42) depending on the rotary piston rotation (14). | ||||||

The invention concerns a metering gear pump comprising a set of gears (3) supported and guided solely by the inner peripheral surface of the lobe of the chamber (110) wherein they are housed. They do not comprise any shaft to act as support or guide, thereby enabling to reduce significantly useless spaces difficult to rinse when changing the product to be pumped. For the same purpose, the driving shaft (40) is flexibly (41, 300) connected to the driving gear (30). Such arrangement provides the advantage of requiring only one single packing seal (5). Such a pump, connected to a drive motor (41) and an encoder (43) delivering a signal proportional to the number of pump cycles, enables to provide an accurate metering pump for numerous uses. |
