    摘要： A method for controlling a pump arrangement upon clogging. The arrangement includes a pump and a control unit. The pump includes a motor, and the control unit drives the motor. The motor during operation is associated with an operational parameter from which the motor torque may be derived. The operational parameter has a normal value PN during normal operation of the motor in a first direction. The method includes the steps of driving the motor in a first direction by the control unit, stopping the motor if a real value P of the operational parameter exceeds a predetermined clogging limit PI, driving the motor in an opposite second direction a predetermined flushing time TR by the control unit, and stopping the motor if the absolute value of the real value P of the operational parameter during the flushing time TR exceeds the absolute value of a first unfastening limit PL1.

    摘要： The invention relates to an adjustable coolant pump for use in the cooling circuit of internal combustion engines. The problem addressed by the invention is that of developing an adjustable coolant pump driven by the engine, which pump requires no external power for pressure or volume-flow adjustment, which guarantees a high reliability and an optimal heating of engines with high engine outputs relative to the engine displacement, which outputs demand coolant pumps of large design. The adjustable coolant pump according to the invention comprises an impeller (5) arranged rotationally fixed on a pump shaft (4) and a spring-loaded ring piston (7) guided axially in a pump housing (1) by a return spring (6), on which ring piston a control slide valve (12) arranged in the pump interior (9) is rigidly fastened, and which is characterized in that the ring piston (7) and a filter sleeve (29) provided with laser holes (28) form together with other components in the interior of the coolant pump a ring-cylinder-shaped spring pressure chamber (31) which is connected to a pressure chamber (18) arranged on the pump shaft side, wherein a pilot valve (20) is arranged on the impeller side end of the pump shaft (4) in such a way that the valve piston (24) closes a shaft bore (25) arranged centrally in the pump shaft (4), which shaft bore discharges into the pressure chamber (18) via cross bores (26) arranged in the pump shaft (4).

    摘要： A method of inhibiting oxygen in ambient air from entering a water supply system having at least one ingress point at which a fluid can enter the water supply system includes supplying an inert gas to the at least one ingress point of the water supply system. The inert gas enters the water supply system at the at least one ingress point and substantially inhibits ambient air including oxygen from entering the water supply system at the at least one ingress point to substantially inhibit oxygen corrosion in the water supply system. Example pump assemblies for coupling to water supply systems, piping networks, and water-based fire sprinkler systems for inhibiting ambient air, including oxygen it may contain, from entering the systems are also disclosed.

    摘要： Pressure volume regulator (20) for control of supply and pressure of barrier fluid for pumps and compressors subsea, comprising an inlet (18) for barrier fluid at an inlet pressure, a first outlet (19) and a second outlet (15), the inlet pressure is higher than the first outlet pressure that is higher than the second outlet pressure. The pressure volume regulator is distinctive in that the inlet and the second outlet are interlocked between a movable longitudinal interlock member (5) with valve elements operatively arranged at either end, the length of the interlock member plus said valve elements is shorter than the distance between an open-close valve mechanism of the inlet and an open-close valve mechanism of the second outlet.

    摘要： The invention relates to the field of mechanical protection devices comprising a transmission shaft (1) with a main axis of rotation (X) and an element (2) that can rupture in the event of a torsional overload, and in particular to a mechanical protection device further comprising a mobile part (3) secured to the transmission shaft (1) in rotation about the main axis (X) and able to move radially outwards with respect to the main axis (X) from a first position to a second position, a spring (4) for urging the mobile part (3) towards the first position, and a tangential end stop (8) able to arrest the rotation of the mobile part (3) about the main axis (X) when the mobile part (3) is in the second position. The mobile part (3) and the spring (4) are calibrated so that once a predetermined triggering angular velocity has been reached, the mobile part (3) moves from the first into the second position under the effect of a centrifugal force that is stronger than the preload of the spring (4).
