摘要： An apparatus for a submersible screw pump includes a cylindrical rotor located inside of a cylindrical stator. The rotor has a screw thread formed in an opposite direction in relation to screw threads of the stator. The external surface of the rotor has a curvilinear shape and the internal surface of the stator has semicircular shapes without rectangular edges. These surface features of the rotor and stator obtain high speed performance for the apparatus with reduced vortices. A gap between the internal surface of the stator and the external surface of the rotor is 0.1-0.2 millimeters. A unloading thrust bearing is attached to a rotor shaft positioned between an intake thrust bearing and the intake end of the rotor. A cavity in the unloading thrust bearing is configured to receive production fluid from the discharge end of the rotor.

摘要： A fluid machine includes a rotary shaft, an operation body configured to discharge fluid by rotation of the rotary shaft, a housing accommodating the rotary shaft and the operation body, and a foil bearing disposed in the housing rotatably supporting the rotary shaft. The foil bearing includes a cylindrical bearing housing, a top foil between the bearing housing and the rotary shaft, and a bump foil between the bearing housing and the top foil and elastically supporting the top foil. The bearing housing has a protrusion protruding inwardly in a radial direction from the bearing housing. The protrusion includes an abutment surface configured to restrict deformation of the bump foil to an elastic range not to reach a plastic range by abutting against the top foil or the bump foil when the top foil is displaced outwardly in the radial direction of the bearing housing.

摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a compressor with a gas bearing supplied with compressed gas and a controller. The controller is configured to determine an inlet pressure and outlet pressure of the gas bearing, determine a maximum speed limit based on the inlet pressure and the outlet pressure, and prevent the compressor from operating at a speed that is greater than the maximum speed limit. A method of controlling a compressor includes calculating a maximum speed limit based on an inlet pressure and an outlet pressure of the gas bearing. The method also includes in response to determining that a speed setting is greater than the maximum speed limit, adjusting operation of the compressor such that a speed of the compressor is at or below the maximum speed limit.

摘要： An oil bearing structure of a fan includes a shaft seat, a rotating shaft, and an oil bearing. The shaft seat includes a boss. A middle portion of the boss defines a slot. One end of the rotating shaft is inserted into the slot. Another end of the rotating shaft is a free end. The oil bearing is sleeved on an outer periphery of the rotating shaft. An axis of the rotating shaft and an axis of the oil bearing are perpendicular to the shaft seat. An effective length of the oil bearing and the rotating shaft is 50%-70% of a length of the fan.
