摘要： Disclosed is an electric fluid pump wherein a radial outer circumferential surface of a stator and an insulating flat surface of an insulating base part, on which crossover wire guides are mounted and which is perpendicular to the outer circumferential surface of the stator, are covered with a synthetic resin coating of predetermined thickness. Since the insulating flat surface of the insulating base part on which the crossover wire guides are mounted and the outer circumferential surface of the stator are covered with the synthetic resin coating, it is possible that, even when a winding force is exerted in a radially inward direction of the stator by winding of crossover wires on the crossover wire guides, the synthetic resin coating on the outer circumferential surface of the stator suppresses changes in the mounting angles of the crossover wire guides and thereby prevents loosening of the crossover wires.

摘要： The invention relates to a fluid pump, in particular to a liquid pump having a rotor with at last one rotor blade for conveying the fluid, the rotor being variable with respect to its diameter between a first, compressed state and a second expanded state. In order to produce a simple compressibility and expandability of the rotor of the pump, it is provided according to the invention that at least one rotor blade is deformable between a first state which it assumes in the compressed state of the rotor and a second state which it assumes in the expanded state of the rotor by means of a fluid counterpressure during a rotation of the rotor during pump operation.

摘要： A tool for installing a flexible impeller within a water pump includes a sleeve having a diameter smaller than an initial diameter of an impeller in a relaxed state, a support extending about an end of the sleeve, and a translation assembly engaged with the support and configured for translating a pushing surface of the translation assembly. In operation, an impeller is contracted into a constrained state and placed in the sleeve, the sleeve is then positioned proximal or in engagement with an opening of the water pump, and the translation assembly is translated such that the pushing surface pushes the impeller into the engine assembly as the translation assembly is translated.

摘要： A mechanical seal has a stationary side seal ring and a rotating side seal ring in opposed sliding contact with the stationary side seal ring. One seal ring of the stationary side seal ring and the rotating side seal ring is disposed on a sealed fluid side and constitutes a slide bearing which supports the rotating shaft. The other seal ring is disposed on the opposite side to the sealed fluid side, and a pressing member is attached to the other seal ring for biasing the other seal ring in the axial direction to press sealing faces of both the seal rings.

摘要： A pump station arrangement and a method for turning off a pump configured for pumping liquid via a conduit. The pump, before being turned off, being driven at an operational frequency (FN) by a control unit. The method is characterized by the steps of, ramping down the frequency of the pump due to a turn off instruction, the terminal frequency of the ramping down being equal to the operational frequency (FN) of the pump minus at least 10 Hz and the ramping down time being at least a reflection time (TR) for the conduit in question, and the terminal frequency of the ramping down not being less than 10 Hz, and stopping the pump after the ramping down.
