Definitions

  • the invention relates to a centrifugal pump unit with the features specified in the preamble of claim 1.
  • Centrifugal pump units of this type in which the rotor is separated from the stator by a split tube, are used in numerous ways, for example as heating circulation pumps, as circulation pumps and the like.
  • the can it is state of the art to form the can as a canned pot, passing through the motor housing.
  • the pot bottom is either formed integrally with the split tube or formed as a separate component, for example as a sealing plug, which is typically accessible from the outside of the motor, so that removed even in the assembled state of the pump, the plug and, for example, a locked rotor solved by manual intervention can be.
  • the gap tube is formed flange. The attachment is typically between the motor and pump housing including this flange.
  • the motor housing is fastened with screws on the pump housing, so that the flange of the split tube and possibly provided seals between them are firmly and tightly clamped.
  • a centrifugal pump unit is offered for example by the applicant under the type designation "Grundfos UP Series 100". This is an in-line pump, in which the motor housing, split tube and pump housing are connected together in the manner described above.
  • Out GB 984 586 A includes a prior art pump assembly in which the can is fixedly connected to the stator of the motor and has a substantially cylindrical shape which is open to the pump and incorporated into a flange of the motor housing.
  • WO 01/27477 A1 includes a pump unit to the prior art, in which the gap tube forms part of the pump housing and the motor housing or the remaining, the gap tube surrounding stator is bolted to the pump housing, so that the stator can be replaced without affecting fluid-carrying lines.
  • the design described there is expensive to manufacture, since the pump housing is constructed of three components.
  • a comparatively large wall thickness of the can causes a reduction in the efficiency of the engine.
  • the present invention seeks to provide a pump unit of the aforementioned type in which the can is fixed pump housing side, so as to form, that the aforementioned disadvantages are reduced.
  • the centrifugal pump assembly has a pump housing accommodating a pump impeller and a motor housing accommodating a stator. It also has a can, in which a drive connected to the pump impeller rotor is arranged, wherein according to the invention, the can is fixed independently of the motor housing on the pump housing.
  • the basic idea of the present invention is thus to fasten the split tube itself to the pump housing, so as to form the fluid-carrying part of the pump set virtually as an assembly unit, the other mounting unit or the other assembly units, which typically include the stator, but also the further engine electronics, in particular frequency converters, terminals, switches, displays and the like may / may be combined to form another assembly unit, which is independent of the other assembly and assembly, so that in repair or maintenance, the latter mounting unit can be removed without the risk of liquid leakage and without the pump side to take any precautions.
  • the can is fixed independently of the pump housing to the motor housing, the liquid-carrying part of the unit from the electrical part is independently handled. It is under canned in the context of the present invention, not only the can in the true sense, ie to understand the pipe section between the rotor and stator, but the whole, the actual canned comprehensive Component, so the canned pot including the wall, which covers the pump housing to the engine out.
  • the can has a flange, with which it connects to the motor-facing side of the pump housing and with which it is preferably screw-mounted on the pump housing.
  • This flange provided on the gap tube serves for fastening the gap tube to the pump housing and forms the wall of the pump housing facing the motor housing.
  • This flange is sealingly connected to the pump housing, so that at the end closed gap tube, be it in the form of a canned pot or in the form of an end closure plug, this canned flange with the stator and possibly arranged in the motor housing motor electronics with respect to the pumped liquid of the pump shields. Because the flange is attached to the pump housing, typically bolted, the motor housing can be removed from the pump housing without having to open the pump housing.
  • the split tube can be made of metal or plastic, is advantageously made as a deep-drawn part of sheet metal.
  • the radial extent of the flange manufacturing technology not too much, according to the invention, canned and flange of two moldings, preferably from correspondingly shaped sheets to produce. These sheets are circumferentially and tightly connected to each other, for example, by a circumferential weld, by gluing, rolling or the like.
  • each of the molded parts has a parallel to the cylindrical portion of the split tube and arranged circumferential portion which these circumferential portions of the mold parts abut each other, preferably there circumferentially welded together are, and form a stiffening rib.
  • the welding in the region of this rib is particularly easy to manufacture, and on the other hand, the rib forms a stiffening component of the flange, so that it can be made more thin-walled.
  • the split tube at its end facing away from the impeller has a receptacle for a closure body, said receptacle is preferably circumferentially welded to the can.
  • Such closure body at the motor end of the split tube are used to vent the can or can solve a blocked rotor by manual intervention.
  • the sealing plug provided in this area must be reliably tight, which is why it is advantageous here to provide a separate receiving component which has a sealing surface towards the sealing plug and which, for example, can receive a thread in order to make a positive connection with the sealing plug.
  • the gap tube should be formed as thin as possible, it is expedient to form such a receptacle as a separate component and then connect to the motor-side end of the can, for example by a circumferential weld.
  • the motor housing with the stator located thereon is detachably fastened to the unit formed from the can and pump housing so that it can be removed or replaced axially in the direction of the can after release of the attachment.
  • the engine electronics or at least a part of the engine electronics can advantageously be arranged surrounding the gap tube between the stator and the pump housing.
  • the engine electronics can be arranged in the motor housing or in a separate, connectable to the pump housing electronics housing.
  • This arrangement is particularly advantageous since this results in an extremely compact design of the unit and can be completely dispensed with the otherwise usual arrangement in the end face or circumferentially arranged on the motor housing terminal box.
  • the power connections can then advantageously be led out parallel to the impeller axis on the outside of the motor housing.
  • This arrangement of the engine electronics also allows optional cooling via the pump or the motor housing or by free convection.
  • fastening means are provided on the gap tube, which define the motor housing on the pump housing.
  • This attachment is suitable for the centrifugal pump assembly according to the invention in a special way, since the motor housing is independent of the can from the pump housing solvable.
  • the fastening can be carried out particularly advantageously via a circumferential groove provided near the motor-side end of the split tube, into which engages at least one latching lug of an end-side plate which is arranged and configured such that it clamps the motor housing between plate and pump housing.
  • This has the further advantage that for removal of the motor housing from the pump housing only this typically at the free end of the engine easily accessible plate must be removed to the motor housing, so the stator and possibly arranged between the stator and the pump housing engine electronics can be removed.
  • This plate is advantageously designed as a rating plate of the unit or carries this.
  • an anti-rotation lock is provided between the pump housing and the motor housing, which is preferably formed by positive-locking means between the motor housing and the pump housing.
