摘要： Method for controlling a compressor element of a screw compressor, where the compressor element has a housing with two meshing helical rotors supported in the housing in the axial direction using at least one axial bearing. The method has a process A and/or a process B, where process A has a first step of switching on a first magnet during start-up of the compressor element, such that the magnet exerts a force on the rotor that is directed from an outlet side to an inlet side, and of switching off this first magnet during nominal operation of the compressor element; and where process B has a first step of keeping a second magnet switched off during start-up of the compressor element, and switching on this second magnet during nominal operation of the compressor element, such that this second magnet exerts a force that is directed from the inlet side to the outlet side.

摘要： A shaft load balancing system includes a housing divided into a first chamber at a first operating pressure and a second chamber at a second, lower operating pressure. A shaft passes from the first chamber into the second chamber. The shaft includes a first end in the first chamber, a second end in the second chamber, and a substantially axial channel connecting the first end and the second end. The first end is in fluid communication with a fluid reservoir in the housing. A reaction member engages the second end. The reaction member includes a compression volume in fluid communication with the channel. A pressure differential between the chambers forces fluid from the fluid reservoir through the channel and into the compression volume. The reaction member transmits the fluid force to the housing, allowing the fluid to create a force on the second end of the shaft. In one embodiment, the reaction member is axially movable on the shaft and rotatable with respect to the housing. In another embodiment, the reaction member is axially movable on the shaft and constrained against rotation with respect to the housing. In a further embodiment, the reaction member is fixed to the housing and restrains radial motion of the shaft. The shaft load balancing system balances pressure-induced, axial shaft loads by generating a force on the second end of the shaft that is approximately equal to the pressure-induced force on the first end of the shaft.

摘要： The invention relates to a compact eccentric screw pump including a sliding articulation. The long-lasting operation of the pump is ensured by a plurality of functions. According to the invention, both the reaction pressure resulting from the transport pressure and the concomitant phenomena emerging from the eccentrically rotating rotor and acting on the articulation and the drive are approximately equalized.

摘要： A single screw compressor structure includes a screw rotor and a casing. The screw rotor has a plurality of helical grooves formed in an outer peripheral surface thereof. The casing houses the screw rotor. The screw rotor includes a main tapered portion having a tapered outer diameter that becomes larger from an intake side toward a discharge side of the screw rotor, and a reversely tapered portion that is located on a downstream side of a maximum outer diameter portion of the outer surface and on the discharge side of the main tapered portion. The reversely tapered portion has a reversely tapered outer diameter that becomes smaller as the reversely tapered portion extends away from the maximum outer diameter portion.
