Definitions

  • the invention relates to a pump unit with the features specified in the preamble of claim 1.
  • Pump units of the type in question which have an electric drive motor and a driven centrifugal pump, are at least pump-side designed as a submersible pump, that is, that the suction port of the pump is immersed in the liquid to be delivered. However, it may also be the entire pump unit designed as a submersible pump, as is one of the state of the art, for example in downhole pumps or basement drainage pumps.
  • JP 2010 190 184 discloses a pump with downwardly directed suction mouth and upstream swirl breaker.
  • Such pumps for cooling and cutting oils are offered with both upwardly directed suction mouth, as well as with bottom-side suction mouth.
  • the invention has the object, a generic pump unit in such a way that it is relatively cheaper to produce, especially taking into account the different types.
  • the pump unit according to the invention has an electric drive motor and a driven centrifugal pump in the form of a submersible pump.
  • the submersible pump has a suction mouth and a suction crusher upstream of the suction mouth.
  • the swirl breaker is formed by at least one component which is releasably secured to the pump unit, wherein the swirl breaker component has an annular attachment portion which engages in the suction mouth of the pump.
  • the basic idea of the present invention is not to design the component (s) that comprise the swirl breaker with the pump housing or the motor chair as in the prior art, but instead instead to form at least one or possibly also a plurality of separate components which can be detachably fastened to the pump assembly. so that they can only be applied to the construction projects in which they are required and, incidentally, that the pump set can be supplied and operated without these components.
  • the basic idea of the invention is therefore to provide a pump unit which can be used optionally with and without swirl breaker, without the need for structural changes or, apart from the swirl breaker component itself, other components.
  • the solution according to the invention has the advantage that, independently of pumps and motor design, the unit can be operated optionally with and without swirl breaker.
  • this embodiment of the invention in which the swirl breaker is designed as a separate releasably attached to the unit component, the advantage that with a suitable design of the component no structural adaptation to the use must be done with or without swirl breaker, so that the related components can be supplied for different purposes, d. H. reduces the variety of parts and thus the manufacturing and storage costs are reduced overall.
  • this swirl breaker component can be provided as a detachable component, which is advantageously attached to the motor chair or the pump or both.
  • the otherwise customary Anformung a swirl breaker on the motor chair which is usually designed as a casting omitted.
  • One or more such swirl crushers can be clamped in a common or separate component in the region of the suction mouth of the pump, on the pump itself or the motor chair or on both, for example.
  • the motor chair has advantageous relative to the shaft axis two oppositely arranged legs, one of which forms the pressure line and the other has only support function.
  • Such a two-legged design has the advantage that a comparatively stable connection between the pump and the motor is provided which makes it possible, despite a relatively long motor shaft, not to have to store it on the pump side, which is particularly favorable since a pump-side bearing often leads to problems. if the pumped liquid is not free of solid or abrasive substances.
  • the arrangement of two legs has the further advantage that the attachment of a swirl breaker component can be done in a simple manner that it is clamped between the legs of the motor chair. It is therefore independent of the pump attachment possible, which may be advantageous.
  • the swirl breaker component is fastened on the pump side with an annular attachment portion, which engages in the suction mouth of the pump and defines the swirl breaker component there.
  • the determination of the swirl component can basically be done in a suitable manner, so for example by screwing, gluing, clamping or the like, a latching and / or clamping attachment is particularly advantageous because it can be done without tools.
  • a clamp-shaped fastening section on the swirl breaker component which surrounds one leg of the motor chair at least in sections, for example with a wrap angle of 200 °.
  • the annular attachment portion In order to fix the annular attachment portion in the suction mouth of the pump is provided according to a development of the invention to provide locking tongues on this annular attachment portion with which engages the spin crusher component latching in a suction mouth forming the pump housing.
  • the latching tongues are advantageously formed in that recesses are provided in the annular attachment portion, which extend in the axial direction and between which locking tongues are formed.
  • the swirl breaker on a flat inner leg which extends radially inwardly from the edge of the suction mouth.
  • a leg in the region of the suction mouth is particularly effective because it influences the flow in the immediate region of the impeller.
  • such an inner leg is integrally formed on the inside of the annular member, with which this is fixed in the suction port of the pump, ie in the corresponding opening of the pump housing. It can also be set several such legs there.
  • the swirl breaker may have a flat outer leg which extends outside of the suction mouth.
  • this flat outer leg is also directed towards the engine and advantageously extends radially between a leg of the motor chair and the drive shaft which projects from the engine through the suction mouth to the impeller.
  • the arrangement in this area can effectively prevent the otherwise typical funnel vortex formation. It is particularly advantageous for liquids that are enriched with air to prevent additional air entry here.
  • a particularly intensive effect is achieved when an inner and an outer leg are provided and they are in relation to each other with respect to the axial direction of the shaft in alignment, that is axially connect to each other. Then the Ansaugwirbel Struktur is effectively prevented from the impeller to wide areas in front of the suction port of the pump.
  • the outer leg is advantageously integrally formed on the annular member, suitably on the side remote from the pump side.
  • the swirl breaker according to the invention may be formed in one or more legs or in another suitable manner. It is also possible for a plurality of swirl crushers to be distributed over the circumference or over the inlet area. It is expedient to connect a plurality of swirl breakers by means of a connecting element to a swirl breaker component in order to produce and install in this way, if possible, only one component.
  • the swirl breaker component can increase the seal between the suction side and the pressure side of the pump, ie at the same time as a seal be educated.
  • a sealing surface is preferably the engaging in the pump housing opening part of the annular member, namely the end face of this component.

  • the motor chair 2 has two relative to the axis of the shaft 7 offset by 180 ° arranged legs 11 and 12. While that in Fig. 1 Left leg 11 has only static function, the right leg 12 is formed as a pressure channel, thus connecting the pressure side of the pump 3 with the molded also on the motor chair 2 near the drive motor 1 connecting piece 13, which serves to connect a line.
  • the pump 3 shown is arranged so that the pump 3 is located with the suction port 5 within the liquid to be conveyed, whereas the drive motor 1 and the connecting piece 13 are arranged above the liquid level.
  • a swirl breaker member 14 is provided in the suction 5 of the pump 3 and between the legs 11 and 12 of the motor chair 2 is fixed.
  • This swirl breaker component 14 is integrally formed as a plastic injection molded part and clamped. It has two swirl crushers 15 and 16, which are integrally formed on a common annular part 17, d. H. are attached.
