摘要： A molten metal pumping device is disclosed that comprises a pump base including at least one input port, a pump chamber, and a discharge leading to an output port. A rotor is retained within the chamber and is connected to a rotor shaft. The device further includes a superstructure attached to and positioned above the pump housing, a motor on the superstructure, a drive shaft connected to the motor and a coupling connecting the drive shaft to the rotor shaft. The rotor extends beyond the input port to deflect solid particles thereby reducing jams and preferably is a dual-flow rotor, directing molten metal both into the chamber and out through the discharge. The coupling is flexible and has two coupling members with a flexible disc disposed therebetween. Another aspect of the invention is a housing for a transfer pump that includes a discharge leading to an output port and a button adaptor extending from the discharge. The button is dimensioned so that it can connect to a metal transfer conduit without the use of cement thereby reducing maintenance costs and downtime. Further, the vertical members such as the support posts, metal transfer conduit and rotor shaft, may be sectional so that anti-corrosive materials may be used for the sections positioned in the most corrosive areas of the molten metal furnace. Additionally, a stationary component of the device may be configured to retain a thermocouple.

摘要： A pipe member is pushed into an inner periphery of a core of an armature to fix the pipe member to the armature. The pipe member is inserted over a fixed shaft. Bearing members have a small hole and a large hole formed at their centers. Pipe member ends are pushed into and fixed to the large diameter holes. The fixed shaft is inserted into the small holes to rotatably support the armature. A guide hole is formed at the center of an impeller of a pump unit, and is fitted to the bearing member, thereby the impeller rotates while the impeller is guided by the outer peripheral surface of the bearing member which rotates integrally with the armature. Coupling protrusions formed on the armature are inserted, and engaged with engagement recesses formed in the impeller to transmit a rotation force of the armature to the impeller.

摘要： A scroll compressor has a shell within which is positioned a frame. The frame is supported by a base portion of the shell to prevent axial movement of the frame with respect to the shell. A motor stator, a main bearing housing and a lower bearing housing are each positioned within the shell by engagement with the frame. A drive member which includes a motor rotor is rotatably supported by both the main bearing housing and the lower bearing housing. The frame, by positioning the motor stator, the main bearing housing and the lower bearing housing, allows the “air gap” between the motor stator and the motor rotor to be accurately controlled.

摘要： A motor/pump system which uses an enclosed rotor shell, and also interior hydrodynamic bearings which are lubricated by the liquid being pumped, is arranged to minimize localized heating at the bearings to vaporization levels under high load conditions. To this end output pressure from the pump, which varies with load, is communicated into the rotor interior, without bulk fluid transfer. The increased pressure raises the vaporization temperature, automatically adjusting it with increased load to maintain the hydrodynamic bearing effect.
