Definitions

  • the invention relates to a housing according to the preamble of the main claim.
  • an inline housing for single-stage pumps which consists of two mold halves, the parting plane of which lies in the plane of the pump shaft.
  • the use of a spiral housing shown requires two different housing halves, which is why two different tools are always required to produce the housing halves for the different sizes of a series.
  • An intermediate wall inserted into the housing is connected to the two housing halves in a plane running transversely to the division plane. This requires additional effort, since these parts have to be subsequently inserted into a housing that has already been manufactured and reliably connected there.
  • an in-line design of the pot housing is provided with molded nozzles and is also equipped with a partition wall which is inserted subsequently.
  • This intermediate housing has at the same time a connection flange for receiving a drive motor and is provided on the side opposite the motor with contact surfaces for a plurality of downstream step housings. There is a separation between the suction and pressure chamber within the intermediate housing and a shaft bushing and a shaft seal are provided on the intermediate wall.
  • the invention has for its object to develop a housing for single or multi-stage pumps in inline design, which can easily absorb and transmit pipeline forces acting on the housing with a simple structure and less expensive manufacture. This object is achieved in accordance with the characterizing part of the main claim.
  • assembly is extremely simple, since the three individual parts forming the housing can be positioned with little effort and can be connected to one another in one setting. This can be done by gluing, soldering, welding or the like. It has the advantage that the joining seam runs only in one plane and the joining process can be carried out easily using automatic machines. For this purpose, the intermediate wall and / or the housing parts lying on the intermediate wall can protrude beyond the housing contour with the aid of an attached flange and can thus be available for welding at the same time.
  • One embodiment of the invention provides that the two housing halves are mirror images, the housing half forming the pressure chamber having a central opening in its bottom region.
  • both housing halves can be created with one mold or one tool.
  • the suction and pressure nozzle parts attached to the intermediate wall rest against and / or protrude into the suction and pressure nozzles formed by the housing halves.
  • the suction and pressure connector parts of the intermediate wall can interact with the suction and pressure connectors of the housing in the most advantageous manner in each case.
  • suction and pressure nozzle parts attached to the intermediate wall are longitudinally divided in the direction of the joining plane.
  • a downstream pump or stage housing seals against the opening of the intermediate wall or, in a known manner, the opening of the intermediate wall forms a corresponding throttle gap for an impeller.
  • the inline-type housing is connected to downstream components by known means.
  • the housing shown in Fig. 1 in inline design consists of two identical housing halves (1, 2), for the manufacture of which only a mold is required.
  • An intermediate wall (3) which is arranged in the joining plane (4) of the two housing halves (1, 2), divides the interior of the housing into a suction chamber (5) and a pressure chamber (6).
  • Suction nozzle parts (7) and pressure nozzle parts (8) attached to the intermediate wall (3) are arranged alternately with respect to the joining plane (4).
  • the integrally formed, longitudinally divided and channel-shaped suction nozzle part (7) is located above the joining plane (4) and extends completely into the suction nozzle (9) formed by the two housing halves.
  • the correspondingly designed pressure port part (8) in the exemplary embodiment lies below the joining plane (4) and within the pressure port (10).
  • An opening (11) made within the intermediate wall (3) enables an overflow from the suction chamber into the pressure chamber, wherein the opening (11) can be followed by an impeller or - as shown in dashed lines - a step housing (12).
  • the upper housing half (1) has a central opening (13), which can be easily manufactured using a simple punching tool.
  • the intermediate wall arranged in the joining plane enables direct frictional connection between the suction and pressure ports, the inclusion of the connector parts attached to the intermediate wall in the connectors attached to the housing representing an optimum in terms of strength.
  • Fig. 2 shows a plan view of the housing in-line design, in particular on the housing half (1), the opening (13) with the underlying partition (3) and the opening (11) made therein.
  • FIG. 3 corresponds to a section III-III from FIG. 1.
  • the joining plane (4) there is the intermediate wall (3) against which the two housing halves (1, 2) rest.
  • the housing halves In the area of the intermediate wall, the housing halves have small flange surfaces (14) by means of which the parts shown can be firmly connected by welding, gluing, soldering or the like. If the parts are welded together, the parts of the intermediate wall (3) and the flange surfaces (14) protruding from the housing can be used as material for the weld seam.
  • FIG. 4 and 5 corresponds to a section along the sectional planes IV-IV and VV from FIG. 1.
  • FIG. 4 how flow-favorably the suction nozzle part (7) formed on the intermediate wall (3) within the two halves of the housing ( 1, 2) suction port is arranged.
  • FIG. 5 the mutual course of the pressure nozzle part (8) attached to the intermediate wall (3) can be seen. It is shaped downwards in order to allow an outflow from the pressure chamber into the pressure port (10).
