  • Patent number: 10090737
    Abstract: A stator for an electrical machine with a stator body (2, 102) and a ground contact (3, 103) which is electrically connected to the stator body, wherein the stator body is arranged in a motor housing (4, 104), which is formed from plastic material. In order to have a compact stator that is easy to install and at the same time has a reliable contact to a ground contact, it is provided that the motor housing has a stator holder (7, 107), which receives the stator body in the operating position, and is located on the inner surface of at least one of its housing parts, and to arrange and fix the ground contact at the inner circumference of the stator holder, facing the stator body, so that the stator body can be electronically contacted by the ground contact.

  • Publication number: 20100007209
    Abstract: A device for supplying power to a load, requiring both a pre-determined supply of electrical power and high power for short durations of the operating cycle of the load, where the operating cycle is repeated. The power supply device includes a connection to an electrical grid, an AC voltage transformation circuit, a voltage rectification means and a plurality of DC/DC converters mounted in series to terminals of the load. Each of the DC/DC converters has a storage capacitor mounted in parallel to it and at least one of the DC/DC converters is supplied directly by the voltage rectification means. At least another one of the DC/DC converters is not supplied directly by the voltage rectification means. The power supply device may compensate for losses in the power supply device and load, and may substantially continually and uniformly balance voltages at terminals of the storage capacitors.

  • Patent number: 4995790
    Abstract: A vertical barrel pump wherein the barrel casing is not provided with an integral flange. The flange is a separately produced part whose upper side is engaged by an external shoulder of the barrel before the pump housing is mounted in and is attached to the barrel by way of the flange. The flange can constitute a base plate which is made of reinforced concrete and is embedded in the foundation of the barrel pump.

  • Patent number: 4799857
    Abstract: A fluid flow machine, particularly a centrifugal pump, wherein the casing has a tubular first portion serving to convey a stream of fluid radially toward a pump shaft which drives one or more impellers. The casing has a second portion with an arcuate band-like wall which spacedly surrounds the shaft and defines a passage having an oval cross-sectional outline and receiving fluid from the outlet of the first portion. A cylindrical outlet of the passage is adjacent the foremost impeller or the only impeller of the pump. One or more guides are provided in the passage to control the flow of fluid from the outlet of the first portion of the casing toward and into the range of the foremost impeller.

  • Patent number: 4753571
    Abstract: A liquefied gas pump wherein a vessel contains a supply of liquefied gas which is pumped from its inlet to its outlet by a multi-stage upright centrifugal pump whose first stage is immersed in the supply of liquefied gas in the vessel. The shaft seal at the upper end of the pump housing is held out of contact with liquefied gas by a first flow restrictor above the last stage of the pump, an expansion chamber which is filled with liquefied gas and is located above the first flow restrictor, a gas collecting chamber between the expansion chamber and the seal, and a second flow restrictor which is disposed between the two chambers and prevents penetration of liquefied gas from the expansion chamber into the collecting chamber. The latter is connected with the vessel and/or with a gas collecting tank. The expansion chamber is connected with the second and/or third stage of the pump in order to ensure that it is filled with liquefied gas.

  • Patent number: 4596476
    Abstract: The thrust bearing for the shaft of a boiler feed pump in a nuclear reactor plant is cooled by a first stream of lubricant which is drawn from a sump by an impeller receiving motion from the shaft. The first stream constitutes one branch of a larger second stream which flows from the discharge end of the impeller. A third stream constituting another branch of the second stream is sprayed against and is cooled by the housing of the feed pump. The first and third streams are caused to reenter the sump by gravity flow. The exterior of the housing is provided with heat dissipating ribs.

  • Patent number: 4563801
    Abstract: The inlet and/or outlet edge of a blank which is to be converted into the vane of an impeller for use in a centrifugal pump is reinforced by providing an exposed surface of the blank with a pair of contiguous recesses which extend along the edge and the deeper of which is immediately adjacent to the edge. The recesses are then filled with metallic armoring material by cladding so that some of the surplus extends beyond the recesses and/or beyond the edge. In the next step, the surplus of armoring material is removed by one or more material removing tools, together with a portion of the blank in the region of the edge so that the exposed surface is provided with a fresh edge which is defined by the armoring material.
