Definitions

  • the invention relates to a pump, in particular a centrifugal pump with a suction and pressure connection, each of which has a measuring point, in particular a pressure tapping point, the measuring points being connected by (one) line (s) to at least one sensor which is arranged within a recess in the pump housing is.
  • the object of the invention is to make the construction of a sensor for a pump of the type mentioned simple and inexpensive. Furthermore, it is an object of the invention to be able to construct the sensor differently and also to be able to change it subsequently, without having to use a completely new sensor. According to the invention, these objects are achieved in that the pump housing partially or completely forms the housing of the sensor in the region of the recess.
  • Such a sensor integrated in the housing no longer requires its own housing, but uses the housing of the pump.
  • a conventional sensor can be split into its components, in order to then assemble them in the recess of the pump as required.
  • the sensor can easily be changed and repaired afterwards.
  • the outer dimensions are smaller.
  • the line (s) leading to the measuring points open into the recess.
  • the individual parts of the sensor in particular a differential pressure sensor, can also lie in the recess. It is proposed that at least one measuring cell be arranged in the recess. It is also advantageous if two pressure measuring cells lie axially one behind the other in the cylindrical recess.
  • At least one electronic component rests in the recess.
  • the parts of the sensor in particular the pressure measuring cell (s) and / or the electronic component, are disk-shaped.
  • the parts lying in the recess can be sealed by sealing rings.
  • the recess opens into the pump housing wall.
  • the recess can be closed on the outside by a stopper, cover or screw.
  • the recess is arranged in or on the flange of a pump connector.
  • the inner end of the recess can also be connected to the interior of the pump connector.
  • the recess is connected to one or both measuring points via at least one line attached to the outside of the pump. Electronics in the sensor can be saved if the sensor is connected to the electronics of the pump.
  • a centrifugal pump has a housing 1 with a suction and pressure connection.
  • the upper pressure nozzle 2 is shown, which ends in a horizontal flange 3, with which the pump can be attached to a pipe.
  • a recess 4 (bore) is made in the wall of the pump housing, in particular in the wall of the connection piece 2, the interior of which is cylindrical with a horizontal cylinder axis.
  • the inner end and thus the bottom 5 of the recess 4 is connected to the inside of the pressure port 2 via a line 6 in the form of a channel or opening.
  • the outer end 7 of the recess 4 opens into the outer wall of the pump housing and can be closed by a plug, cover or screw 8. In the latter case, the outer end 7 has an internal thread.
  • the lower wall of the recess 4 has an opening 9, in particular in the form of a vertical bore, to which a line, not shown, can be connected.
  • This line is preferably fastened on the outside in particular in an outer groove of the pump housing and leads to a measuring point of the lower suction nozzle of the pump, not shown.
  • At least one measuring cell is inserted from the outside, as was previously used in the housing of a sensor, in which case the sensor housing can be omitted since it is formed by the pump housing or by the recess 4.
  • the pressure measuring cell 10 is disc-shaped with a cylindrical outer edge, so that one can speak of a tablet shape of the measuring cell. In this case, more than one measuring cell can be arranged, so that it is particularly easy to carry out to measure a differential pressure which is present via the line 6 and the opening 9.
  • the electronics module can be absent and the recess 4 can be electrically connected to the electronics of the pump.
  • the recess 4 with its cylindrical wall can protrude beyond the outside of the housing 1 or the outer wall of the housing 1 forms an extension at the location of the recess, so that the recess 4 can have a sufficiently large length to accommodate enough building blocks can.
  • the stopper, the cover or the screw 8 can have an inner recess which opens towards the recess 4 in order to also be able to accommodate components.
