A radial compressor unit for compressing gas has several compressor stages. Each compressor stage includes an impeller having rotor blades, and a flow channel arranged downstream of the impeller, as viewed in the flow direction of the gas to be compressed, having a diffusor section, a deflection section, and a recirculation section having guide blades. The gas compressed in a compressor stage can be removed as cooling gas for cooling a component to be cooled, and can be conveyed in the direction of the component to be cooled. The cooling gas can be removed adjacent to an intermediate wall of the compressor stage from the deflection section and/or the recirculation section of the flow channel of the compressor stage.

A system includes an inductor assembly of an agricultural implement having an inductor box with a wall configured to separate an interior of the inductor box from an exterior of the inductor box, an inductor segment, and a mounting clip. The wall includes an inner surface in the interior and an outer surface on the exterior. The inductor segment includes a mixing portion and a delivery portion, wherein the mixing portion interfaces with the inner surface and is configured to mix agricultural product and airflow into a mixture. The delivery portion is configured to convey the mixture through the wall. The mounting clip is configured to form a seal between the interior and the exterior of the inductor box, and to interface with the outer surface and the delivery portion in an installed position to couple the inductor segment to the inductor box.

A centrifugal compressor includes a casing, a first compression mechanism and a second compression mechanism. The casing has a first inlet portion, a first outlet portion, a second inlet portion and a second outlet portion. The first compression mechanism includes a first inlet guide vane disposed in the first inlet portion, a first impeller disposed downstream of the first inlet guide vane, a first diffuser disposed in the first outlet portion downstream from the first impeller, and a first motor. The second compression mechanism includes a second inlet guide vane disposed in the second inlet portion, a second impeller disposed downstream of the second inlet guide vane, a second diffuser disposed in the second outlet portion downstream from the second impeller, and a second motor. The first and second motors are arranged to rotate first and second shafts in order to rotate the first and second impellers.

A blower of the present disclosure includes: a lower case having a suction port; an upper case which has a pair of towers that are spaced apart from each other and form a space through which a discharge air flows therebetween; and a blower fan which is disposed inside the lower case and discharges air to the upper case, wherein each of the pair of towers has a discharge port that is elongated in an up-down direction and disposed closer to a rear end of the tower than a front end, and has an air guide, which is disposed therein, that guides the air discharged by the blower fan to the discharge port, wherein the air guide is convex upward, has one end disposed near a middle between the front end and the rear end of the tower, and has the other end disposed near a middle of a vertical height of the discharge port, wherein the other end is disposed higher than the one end, so that the direction of air flow discharged from the fan can be smoothly switched to the discharge port side by only a single air guide, thereby minimizing the flow resistance inside the blower and greatly improving the economic efficiency and manufacturability of the blower.

A cleaning system comprises a power plant, a regenerative blower having a power input shaft, a suction port, and a discharge port, an interface assembly configured for transmitting power from the power plant to the regenerative blower, a pump configured for generating pressurized water, and a heat exchanger system configured for heating the pressurized water.

The invention relates to a side-channel machine having a housing (4a), located in the housing (4a) a side-channel (28) for guiding a gas, and at least one gas inlet opening (34) which is formed in the housing (4a) and is fluidically connected to the side-channel (28). Furthermore, the side-channel machine has at least one gas inlet pipe (29a) which connects to the at least one gas inlet opening (34), The side-channel machine further comprises at least one gas outlet opening (33) and at least one gas outlet pipe (31a) which connects to the at least one gas outlet opening (33). Furthermore, the side-channel machine has an impeller that can be made to rotate in the housing (4a), with impeller blades, which bound impeller cells arranged in the side-channel (28), for delivering the gas in the impeller cells from the at least one gas inlet opening (34) to the at least one gas outlet opening (33). The side-channel machine further has at least one interrupter (39) arranged between the at least one gas inlet opening (34) and the at least one gas outlet opening (33).

A side channel compressor for compressing a gas includes a housing and at least one impeller which is arranged in the housing and configured to bedriven in rotation about a central axis. In addition, the side channel compressor includes at least one seal assembly arranged in the housing and including at least one sealing device configured to seal at least one gap between the housing and the at least one impeller and be forced radially outward with respect to the central axis in order to keep the at least one gap small. The at least one seal assembly also includes at least one sealing-device-holding device configured to hold the at least one sealing device in an axially secured fashion with respect to the central axis and which includes at least one main holding body.

A casing of a centrifugal compressor has a first wall facing a back surface of an impeller. A back gap is formed between the back surface of the impeller and the first wall. A specific speed of the impeller is set to be less than 0.1. A ratio of an axial width s of the back gap to an impeller radius r satisfies a relationship of 0.008s/r0.5, where the axial width s is a width of the back gap in an axial direction of the shaft, and the impeller radius r is a radius of the impeller.

An impeller for a ventilation unit, especially for use in plants for the aerobic treatment of organic waste, is provided. The impeller comprises a housing, a pair of mutually facing plates received within the housing and provided centrall with a through-hole for a cylindrical hub, and a plurality of first radial blades arranged between the plates. The impeller further comprises second radial blades arranged on at least one plate, on its side facing the inner wall of the housing and extending from the cylindrical hub toward the periphery for creating an under-pressure zone in the central region of the impeller itself, at its hub. Thanks to this measure, condensate water deriving from the humidity of the air sucked/blown by the ventilation unit is prevented from leaking along the rotation shaft of the impeller, towards its motor and towards the outside environment.
