摘要： Electrochemical machining is used to generate the helical lobe profiles of the stator of a progressive cavity pump or motor. A thin, elastomeric liner, of uniform thickness is bonded either to the interior of the stator, or to the exterior of the rotor. Where the elastomeric liner is to be bonded to the interior of the stator, bonding is improved by electrically etching the interior of the stator during the electrochemical machining process to produce a roughened surface.

摘要： A fluid pump includes a housing having a lateral wall and an end wall, an insert located in the housing surrounded by the lateral wall and including a body having a central aperture and inlet and outlet fluid channels. A seal, located between the end wall and the insert, seals against fluid flow therebetween. A Gerotor pump mechanism located in the housing adjacent the inlet and outlet fluid channels includes a outer gear and an inner gear engaged with the outer gear for pumping fluid from the inlet fluid channel to the outlet fluid channel as the inner gear rotates relative to the outer gear. A cover, fitted in the housing and spaced axially from the end wall, is located adjacent the inner gear and outer gear and is secured to the housing.

摘要： Stator for an eccentric single-rotor screw pump has a casing made of steel or the like and a helical elastomer lining. Stator and a method for its production are described which can also be made with larger lengths at low production costs. Stator is composed of at least two stator segments that are axially arranged in a line, whereby the stator segments are connected to one another at their abutment so as to be pressure-tight by a tube of a polymer material that is pulled onto the casing and overlaps the abutments and by a metal ring radially pressed onto it.

摘要： An apparatus for removing a stator tube from a position about a rotor of a progressing cavity pump is provided. The apparatus includes an actuator assembly having a base and a piston which is longitudinally displaceable relative to the base, and a pusher rod. The base of the actuator assembly is removably attachable to a discharge end of the stator tube. The pusher rod is longitudinally releasably attachable to the piston at a plurality of locations along the length of the pusher rod and is located to engage the rotor when the base is coupled to the stator tube. The pusher rod is coupled to the piston and the piston is driven by the actuator assembly. With only slight modifications the apparatus may also be used to install the stator tube on the rotor when operated in a substantially opposite way.

摘要： A screw compressor includes a suction end, a discharge end, first and second rotors mounted for rotation between the suction end and the discharge end, and a discharge housing at the discharge end. The discharge housing surrounds a portion of the first and second rotors and includes an end surface. The compressor further includes a first axial bearing supporting the first rotor, and a wear-preventing member sandwiched between the end surface of the discharge housing and the first axial bearing such that no portion of the first axial bearing contacts the end surface. The screw compressor further includes a first radial bearing in the discharge housing for supporting the first rotor. The wear-preventing member includes a face abutting the end surface of the discharge housing and abutting at least a portion of the first radial bearing to retain the first radial bearing in the discharge housing.

摘要： The invention concerns a micropump for the substantially continuous delivery of a mass flow, the micropump having a sleeve axis and an offset axis of rotation. An internal rotor meshes with an external rotor in a sleeve and at least one outlet-side pressure opening in a first end-face termination part. Both rotors have a dimension smaller than 10 mm. The invention further concerns a micromotor of similar construction in which the diameter of rotors and the casing are below 10 mm. The pump and motor are extremely miniaturized yet still permit a continuous flow with high feed pressure and high output.
