摘要： A fan central tube coupling structure includes a base and a central tube. The base has a first section and a second section that together define an upward tapered receiving recess below the base. The central tube is externally provided on around a bottom end with a first and a second protruded section and an engagement groove defined between the first and second protruded sections. The second protruded section has an interference pressing surface defined on an outermost peripheral surface thereof. The central tube is axially extended through the base, such that the second protruded section is axially press-fitted into the tapered receiving recess and the interference pressing surface is radially outward forced against the tapered receiving recess. In the meantime, the second section of the base is fitted in the engagement groove and clamped in place by between the first protruded section and the second protruded section.

摘要： A torque transfer system for centrifugal pumps. A torque transfer system for a centrifugal pump includes a bearing sleeve above an impeller, the bearing sleeve and a hub of the impeller surrounding a rotatable shaft and coupled to the rotatable shaft by a key, the bearing sleeve having a stepped bottom edge, a top edge of the hub stepped inversely to the bottom edge of the bearing sleeve such that the top edge and the bottom edge interlock with a clearance between longitudinally extending portions of the interlocked edges, wherein upon reduction of torque transference between the key and the sleeve, the clearance closes such that the longitudinally extending portion of the stepped top edge contacts the longitudinally extending portion of the stepped bottom edge thereby maintaining rotation of the sleeve with the rotatable shaft. A centrifugal pump includes modules with a series of stepped, interlocked impellers.

摘要： A submersible well pump assembly has upper and lower seal sections connected between the pump and a motor. The seal sections have drive shafts with thrust runners that engage thrust bearing bases. The upper drive shaft will undergo a limited amount of downward movement toward the lower drive shaft in response to wear of the upper thrust bearing base. A spring between ends of the drive shafts transfers a portion of the down thrust on the upper drive shaft to the lower drive shaft prior to the limited amount of downward movement of the upper drive shaft toward the lower drive shaft being reached. A rigid stop member in the coupling transfers down thrust directly from the upper drive shaft to the lower drive shaft, bypassing the spring, only after the limited amount of downward movement of the upper drive shaft toward the lower drive shaft has been reached.

摘要： A system for hydraulically fracturing an underground formation in an oil or gas well, including a pump for pumping hydraulic fracturing fluid into the wellbore, the pump having a pump shaft, and an electric motor with a motor shaft mechanically attached to the pump to drive the pump. The system further includes a torsional coupling connecting the motor shaft to the pump shaft. The torsional coupling includes a motor component fixedly attached to the motor shaft and having motor coupling claws extending outwardly away from the motor shaft, and a pump component fixedly attached to the pump shaft of the pump and having pump coupling claws extending outwardly away from the pump shaft. The motor coupling claws engage with the pump coupling claws so that when the motor shaft and motor component rotate, such rotation causes the pump component and the pump shaft to rotate, thereby driving the pump.

摘要： A direct drive pump employs an on-off tool to attach the drive rod string to a floating pump drive shaft in both torsion and tension. The downward thrust on the drive shaft, as well as the weight of the drive rod string, is born by a thrust bearing in the drivehead at the surface. A floater pump is used with this direct drive pump to permit the free vertical movement of the drive shaft. When a tandem direct drive pump is employed a housing containing a tandem pump drive shaft connector connects the shafts in an upper and lower tandem pump to permit the two to freely move in the tandem direct drive pump.

摘要： An electrical submersible pump (ESP) having a sleeve coupled to the shaft that rotates as the shaft rotates. The sleeve can be a base portion of a pump impeller, a journal bearing, or a bushing. A drive collar mounts around the shaft and has an end with a portion that projects past an end of the sleeve profiled to correspond with the shape of the projecting portion. As the shaft rotates the drive collar the projecting portion of the drive collar pushes against the profiled end of the sleeve to rotate the sleeve. The projecting portion can be a wedge shaped tab on the drive collar, or an angular segment of the drive collar extending axially past the remaining segments. The profiled end of the sleeve can include a recess formed to receive the tab and can have an angular segment corresponding to that on the drive collar.

摘要： Improved components for a molten metal pump include a coupling for connecting a rotor shaft to a motor shaft, a rotor shaft and a rotor. The rotor shaft has a first end and a second end wherein the first end optionally has a vertical keyway formed in the outer surface of the shaft. The second end optionally has flat, shallow threads. The coupling can be one-piece or multi-piece, includes a cavity for receiving the first end of the rotor shaft and, if the first end of the rotor shaft has a keyway, the coupling includes a projection in the cavity for being received at least partially in the keyway. The rotor includes a connective portion that connects to the second end of the rotor shaft. If the second end of the rotor shaft includes flat, shallow threads, the connective portion is essentially a bore having flat, shallow threads configured to receive the second end of the rotor shaft. Optionally, the first end of the rotor shaft may have flat, shallow threads in which case the coupling would have a cavity that receives the first end of the rotor shaft, wherein the cavity has flat, shallow threads.

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.
