摘要： A supercharger that receives and/or generates high pressure boost air and contains gear lubrication includes a housing, a rotor coupled to a rotor shaft rotatably supported in the housing, and a high pressure rotor seal disposed about the rotor shaft. The high pressure rotor seal includes a primary lip configured to contact the rotor shaft and be exposed to the gear lubrication, and at least one boost pressure blocking lip configured to contact the rotor shaft and maintain a seal against the rotor shaft when the high pressure boost air acts thereon.

摘要： Disclosed are an exhaust bearing seat, a screw compressor and an air-conditioning unit. The exhaust bearing seat is provided with a discharge port (1), wherein an opening of the discharge port (1) is orientated in such a way that, if the exhaust bearing seat is sheathed in a housing, gas exhausted from the discharge port (1) has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port (1) is able to guide the gas flow to rotationally flow along the inner wall of the housing body and around the axial direction of the housing, which extends the flow path of the gas flow inside the housing, and facilitates the reduction of noise of the gas flow pulsation.

摘要： The invention relates to a liquid ring pump (1) for generating vacuum and for pumping a flow of sewage in a vacuum sewage system. The liquid ring pump comprises in the direction of the flow of sewage a pump inlet (11), an inlet chamber (13), a pump housing (14) provided with a rotor (15) arranged on a drive shaft(16) provided with a mechanical seal (20), an outlet chamber(17), and an pump outlet (19). The mechanical seal (20) is arranged within the outlet chamber (17). The outlet chamber (17) is provided with an integrated extension (18) providing an enlargement of the outlet chamber (17)in order to retain the flow of sewage in the outlet chamber (17) before it is discharged from the pump outlet (19) in order to improve the lubrication of the mechanical seal (20).

摘要： A method for mechanically heating a liquid mixture of substances is described. In a liquid-ring pump (1), a foam phase is compressed and the compression heat is transferred to the mixture of substances. An apparatus designed as a liquid-ring pump (1) for mechanically heating a liquid mixture of substances is also described. Said liquid-ring pump (1) comprises an impeller (12) eccentrically arranged in a cup-shaped pump housing (11) as well as a tangential suction port (13) and a tangential delivery port (14). A gas port (15) for introducing an inert process gas extends into the suction port (13) and/or into the cup-shaped pump housing (1).

摘要： A liquid ring gas pump having two axially adjacent, serially connected stages. Gas to be compressed is admitted to the first stage of the pump solely via a first stage inlet opening at the end of the first stage remote from the second stage. The sole outlet for gas to leave the first stage in order to flow to the second stage is a first stage outlet at the end of the first stage adjacent to the second stage. A residual gas outlet is provided at the end of the first stage remote from the second stage for allowing compressed gas that is unable to exit via the first stage outlet to exit via the residual gas outlet and re-enter the first stage via a residual gas inlet also provided at the end of the first stage remote from the second stage and located after the first stage inlet but before the first stage outlet in the direction of rotor rotation.
