Definitions

  • the invention relates to a housing for a pump, in particular for a centrifugal pump with a suction and pressure port, each of which has a measuring point, in particular a pressure tapping point, the measuring points being connected by at least one line to a sensor, in particular to a differential pressure meter.
  • the object of the invention is to improve a housing of the type mentioned at the outset in such a way that the line (s) connecting the measuring points is / are easily accessible with simple construction, manufacture and assembly, in particular for maintenance, cleaning and replacement.
  • Such a line guided in a groove on the outside of the housing is easily accessible and thus not only easy to replace, but also easy to clean. Furthermore, the line can lie so far in the groove that it is protected against damage.
  • the cross section of the groove is part-circular, in particular semicircular. Production is simple if the groove is milled into the outer wall of the housing.
  • the cross section of the groove corresponds to at least part of the cross section of the line.
  • the line can also be held in the groove by clamping force.
  • a sensor system in particular a pressure sensor system
  • the sensor system can be attached to the outside of the pump housing, in particular to one of the nozzles near the nozzle flange.
  • a centrifugal pump has a housing 1, with a suction nozzle 2 and a pressure nozzle 3. Both nozzles have a flange 4 for attachment.
  • a bore 5 is made in the flange or in the pump housing wall, which leads to the inside of the connecting piece in order to form measuring points, in particular pressure tapping points.
  • Both bores 5 are closed by a plug with a screw and cross bores 8, 9 extend from both bores 5, to which at least one line 10 can be connected.
  • This line leads to a sensor, not shown, in particular a differential pressure meter, which is either interposed in the line or lies in one of the two bores 5.
  • a groove 12 is made, in which the line 10 is particularly fastened by being clamped.
  • the line can be partially or completely received by the groove 12.
  • the cross-sectional shape of the groove 12 preferably corresponds to the outer cross-section of the line 10.
  • the cross-section of the groove 12 is preferably part-circular, in particular semi-circular, and the cross-section of the line 10 is circular.
  • the groove 12 can be produced when casting the pump housing or can be milled in afterwards.
