| PURPOSE: To make the starting torque small by providing the exhaust port of a pump at an substantially same level with the center of an impeller at an end face of a cylindrical casing which surrounds the impeller, and arranging a water separator on the lower side of the exhaust so as to communicate therewith. CONSTITUTION: On an end face of a cylindrical casing of a pump 11 exentrically surrounding an impeller 3 is mounted a side cover 5 having an upward suction port 5a connected to a suction pipe 9 and an outlet 15 provided at a substantially same level with the center of the impeller 3. To the exhaust port 15 is connected an exhaust pipe 20 whose tip end is open within a water separator 12 arranged at the lower side of the pump 11. With a result, a the start of operation, a casing 4 will not be filled up with the working water, and the starting operation can thus be done with a small starting torque.

| 67 | Pump Assembly and Method for Evacuating a Vapor-Filled Chamber | US14762005 | 2014-01-16 | US20150361979A1 | 2015-12-17 | Heiner Kösters; Matthias Tamm; Daniel Schütze |
| The invention relates to an assembly comprising a vacuum pump and a chamber, wherein a suction tract extends between the chamber and the vacuum pump. The vacuum pump is a liquid ring machine. According to the invention, a liquid outlet is arranged in the suction tract in order to add liquid to gas sucked in from the chamber. The invention further relates to a method for evacuating a chamber filled with vapor. According to the invention, the vapor is condensed by introducing additional liquid into the suction tract, thus by co-condensation. By supplying liquid selectively only when liquid is required for the condensation of the vapor, water is saved. | ||||||

| 70 | Vacuum source and float valve for a self-priming pump | US12881064 | 2010-09-13 | US08246316B2 | 2012-08-21 | David Muhs |
| A self priming pump system that includes a motor coupled to a centrifugal pump. A separator having a reservoir is provided for storing a limited amount of pumped fluid in advance of the centrifugal pump. A vacuum source provides a vacuum suction to the reservoir to draw pumped fluid into the reservoir to prime the pump. A float may be provided, wherein when the fluid level in the reservoir reaches a desired level, the float opens a float valve to let air into the reservoir to maintain the desired level. The float valve may have a capacity that is greater than or equal to the pumping capacity of the vacuum pump, or at least large enough to make up for a difference between the pumping capacity of the vacuum pump and an amount of fluid that can be pumped by the centrifugal pump from the reservoir. | ||||||

| The method and system relate to reducing the content of hazardous chemicals when handling malodorous gases emanating from a pulp mill and before burning said malodorous gases in final incineration equipment in oxygen excess environment in order to oxidize the sulphur compounds. The flow of malodorous gases is transported to final incineration (C2) by using liquid ring pumps. The hazardous chemical, preferably ammonia, is bound or dissolved in the liquid used in the liquid ring pump. A part of the liquid used in the liquid ring pump is bled off to final destruction different than the final incineration equipment in oxygen excess environment. | ||||||

Also, the configuration of a tank used to store liquid for the vacuum pump system may be configured to separate and collect sediments near a drain port, which then can be easily drained.

| The invention relates to rotary machines, with nonparallel rotor and pistons axes of rotation. A spherical cavity (4) formed by a body (1) comprises a rotor (7), which is arranged therein and is provided with a through slot (21) in which a piston (8) in the form of a through-cutout (33) disk is mounted in such a way that it is enabled to perform rotational oscillatory motions. The working cavity is divided into bypass (2) and pressure (3) sections. A C-shaped separator (9) is placed in the bypass section (2) and separates the working medium input window (12) from the output window (13) thereof. In the pressure section (3), the working medium is pushed by the projecting part of the piston (8). The inventive spherical positive displacement rotary machine enables uniform flow rate throughout the cycle. The input and output windows are spaced along a shaft, thereby making it possible to develop, on the basis of said machine, multistage down-hole pumps and hydraulic drives. A high tightness and a low internal hydraulic resistance render the inventive machine effective within a large range of viscosities of the working medium. The simple geometrical shape and the interaction of ‘plane-with-plane’ and ‘sphere-with-sphere’ contacting parts provides the machine with an extended service life. | ||||||
