    摘要： A liquid jet pump for moving a wide variety of material is described. The liquid jet pump is comprised of a nozzle assembly and a target tube, and defines a suction chamber. The nozzle assembly is configured to pull in gas, causing a gas bearing effect wherein a layer of gas surrounds the liquid jet flow exiting the nozzle assembly. The liquid jet passes through the suction chamber with minimal deflection, reducing cavitation and improving mixing as educted materials enter the suction chamber and combine with the liquid jet. The combined material is directed into the target tube, which preferably is designed to detach from the other components and is composed of abrasion-resistant material. The target tube absorbs the majority of wear, and provides ease of changing parts. The nozzle assembly is preferably positioned within the suction chamber in a way which maximizes vacuum, and the vacuum is maintained in relation to the pressure or vacuum produced by a downstream pump in a unique way, by controlling the gas flow into the nozzle assembly. In this way, the pump realizes drastic and surprising increases in solids pumping efficiency and solids/liquid mixing efficiency.

    摘要： An improved liquid jet pump for moving solid or other materials is provided. The liquid jet pump includes a nozzle assembly, a suction chamber, and a target tube. The nozzle assembly pulls in atmospheric air, causing an air bearing effect around the liquid jet exiting the nozzle assembly. The liquid jet passes through the suction chamber with minimal deflection, reducing cavitation and improving mixing as educted materials enters the suction chamber and combines with the liquid jet. The combined material is directed into the target tube, which is designed to detach from the other components and is composed of abrasion-resistant material. The target tube absorbs the majority of wear, and provides ease of changing parts.

    摘要： The mixing chamber of a liquid jet apparatus is composed of a convergent inlet section and a cylindrical outlet section and the ratio between of the surface area of the minimal cross-section of the mixing chamber and the surface area of the inlet cross-section of the mixing chamber ranges from 0.005 to 0.392, and the angle of inclination between either the ruling line of a conical surface forming the convergent inlet section of the mixing chamber or the tangents to each point of a curved surface forming the convergent inlet section and the flow axis of the mixing chamber ranges from 30′ to 10°. In another embodiment of the jet apparatus, the whole mixing chamber converges in the flow direction and the ratio of the surface area of the minimal cross-section of the mixing chamber to the surface area of the inlet cross-section of the mixing chamber ranges from 0.005 to 0.392, and the angle of inclination between either the ruling line of a conical surface forming the convergent mixing chamber or the tangents to each point of a curved surface forming the convergent mixing chamber and the flow axis of the mixing chamber ranges from 30′ to 10°. A jet apparatus realized according to the above-mentioned dimensions exhibits an improved efficiency.
