摘要： The invention relates to a method for controlling a rotary screw compressor, having at least a first and a second air-end, wherein both air-ends are driven separately from one another and speed controlled. According to the invention, the following steps are carried out: detection of a volume flow taken at the outlet of the second air-end; adjustment of the rotational speed of both air-ends, when the removed volume flow fluctuates in a range between a maximum value and a minimum value; opening of a pressure-relief valve, if the volume flow falls below the minimum value; and reduction of the rotational speed of at least the first air-end to a predetermined idling speed (V1L) to reduce the volumetric flow delivered by the first to the second air-end.

摘要： A fault-rectification method for an eccentric screw pump of a conveying apparatus for conveying viscous construction materials, comprising the steps of monitoring a start of a conveying operation of the eccentric screw pump by way of a characteristic-variable-monitoring program of a control device of the conveying apparatus, wherein a working-free program is executed by the control device of the eccentric screw pump if, for one or more characteristic variables. The characteristic-variable-monitoring program acquires characteristic-variable values which are stored, alone or in combination with one another, as fault values that indicate jamming of a rotor/stator unit of the eccentric screw pump, and wherein otherwise a conveying operation is begun. The eccentric screw pump is operated in the working-free program in such a way that an electric motor of a drive unit of the conveying apparatus is multiply alternately switched on and switched off.

摘要： A positive displacement rotary compressor is designed for near isothermal compression, high pressure ratios, high revolutions per minute, high efficiency, mixed gas/liquid compression, a low temperature increase, a low outlet temperature, and/or a high outlet pressure. Liquid injectors provide cooling liquid that cools the working fluid and improves the efficiency of the compressor. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns.

摘要： A variable displacement lubricant pump includes a first plunger which pushes a shiftable control ring into a high pumping volume direction. A pump rotor comprises radially slidable vanes which rotate in the control ring. A pressure control system comprises a first pressure control chamber wherein a first plunger is axially moveable. A first pressure conduit connects a pump outlet port with the first pressure control chamber. A first pressure control valve controls a pressure in the first pressure control chamber. A second pressure control valve between an outlet opening in a side wall of the first pressure control chamber and a low pressure source controls the outlet opening and is a centrifugal valve mechanically connected with the pump rotor which closes at a high rotational speed of the pump rotor. The outlet opening is closed by the first plunger in a low pumping volume position and opened in a high pumping volume position.

摘要： A gear pump comprises a casing having an inlet, an interior, and an outlet. An inlet gear is positioned at the inlet and pressurizes fluid received at the inlet. A drive gear is positioned at the outlet of the casing, the drive gear receiving fluid pressurized by the inlet gear to output pressurized fluid at the outlet. A speed-reduction gear is meshed to the drive gear and connected to the at least one inlet gear, the speed-reduction gear having a greater number of teeth than the drive gear to reduce a rotational speed from the drive gear to the inlet gear, such that the inlet gear has a lower speed that the drive gear. An input shaft is coupled to the drive gear and receives a rotational input to actuate the drive gear.

摘要： A rotary compressor includes a rotation mechanism, an annular piston and a blade. The rotation mechanism has a cylinder with an annular cylinder chamber. The annular piston is contained in the cylinder chamber eccentrically from the cylinder and sectioning the cylinder chamber into an outer compression chamber and an inner compression chamber. The blade is disposed in the cylinder chamber and sectioning each of the inner and outer compression chambers into a high-pressure side and a low-pressure side. The rotation mechanism compresses a fluid by relatively rotating the cylinder and the piston. The outer compression chamber serves as a low-stage side compression chamber for compressing a low-pressure fluid into an intermediate-pressure fluid. The inner compression chamber serves as a high-stage side compression chamber for compressing the intermediate-pressure fluid compressed in the low-stage side compression chamber into a high-pressure fluid.

摘要： The present invention aims to provide a motor-mounted internal gear pump that is small-sized, less expensive and has high reliability, while utilizing a function of an internal gear pump that is suitable for high head. A motor-mounted internal gear pump has a pump section for sucking and discharging a liquid and a motor section for driving the same. The pump section has an internal rotor having teeth formed around its outer periphery, an external rotor having teeth formed around its inner periphery and a pump casing that accommodates both rotors and has a suction port for sucking a liquid and a discharge port for discharging a liquid. The motor section has a can that composes a part of the pump casing and formed of anon-magnetic material into a thin plate, a rotator arranged at the inside of the can for driving the external rotor or the internal rotor; and a stator arranged at the outside of the can for rotating the rotator.

摘要： In a regulating device for positive-displacement pumps, in particular vane cell and roller cell pumps, a pressure chamber of the pump can be connected with an outlet duct (14) via a bore (13), in which a regulating piston (17) is displaceable against the force of a spring (16). A flow control valve (11) is arranged for regulating a useful flow. In the area of the bore (13) containing the regulating piston (17), the pressure chamber is in continuous connection with a spring chamber (15) of the regulating piston (17) via a bypass duct (18). As a function of the delivery flow of the positive-displacement pump, the regulating piston (17) controls the open cross-sectional surface of a throttle duct (12), which connects the spring chamber (15) with the outlet duct (14). The regulating piston (17) has a control edge (19), by of which the open cross-sectional surface of the throttle duct (12) is reduced during a movement of the regulating piston (17) in the direction toward the spring chamber (15). The regulating piston (17) moreover has a further control edge (20) which, in the course of a further movement of the regulating piston, increases the open cross-sectional surface of the throttle duct (12).
