Definitions

  • the invention relates to a borehole pump according to the features specified in the preamble of claim 1.
  • the invention has the object, a generic borehole pump in such a way that one or more sensors can be arranged inexpensively at a suitable location and corresponding signal or data connected.
  • the borehole pump according to the invention has an electric drive motor and a single-stage or multi-stage centrifugal pump driven by it.
  • one or more sensors of the pump are arranged in a sensor housing, which, liquid flows through and liquid surrounds.
  • the sensor housing is located between the motor and the pump, at the end of the pump or inside the pump.
  • the sensor housing can either be arranged as a separate housing at the end of the pump or form part of the pump housing, so be formed integrally with this.
  • the basic idea of the present invention is, if possible, to accommodate the complete sensor system, but at least one or more sensors in a separate sensor housing, which at the end the pump, within the pump or between the motor and the pump, that is arranged at the other end of the pump.
  • This sensor housing may have a modular design, so that it can optionally be retrofitted to existing pumps or at least pumps of the same series can be equipped with or without sensor housing, so can be shipped with and without sensors. Since the sensor housing is arranged between the motor and pump, within the pump or at the end of the pump, the borehole pump is thereby not changed in its outer contour, but only in their length, which is particularly important for borehole pumps.
  • the sensor housing according to the invention is designed and arranged in such a way that liquid flows through it and liquid is surrounded on the one hand. For example, temperatures and / or pressure can be detected by both the surrounding and the delivered fluid. Since, if possible, the entire sensor system or at least a large part is arranged inside the sensor housing, only that sensor housing needs to be provided with an outwardly directed cable, which is an advantage in borehole pumps when the sensor housing is arranged at the upper end of the pump on which anyway only the power cable runs next to the conveyor line. In the arrangement between the motor and pump, there is the advantage that the wiring can be done via the motor, which anyway requires a cable to the outside to the electrical power supply and possibly also to the control electronics.
  • the sensor housing is divided into a liquid-conducting housing part and a liquid-free housing part, which are separated by a preferably formed by stainless steel sheet housing wall.
  • a housing wall may be formed in the manner of a split tube comparatively thin but absolutely liquid-tight, so that, with the exception of the pressure and / or differential pressure sensors, if necessary, it is also possible to measure through the housing wall, for example temperature, vibration and the like.
  • the entire flow of the pump is passed through the liquid-carrying housing part, wherein the housing part is formed so that it is almost a further pump stage or a pipe extension, that provides as little flow resistance.
  • the sensors located in the sensor housing and possibly electronics requires comparatively little space, so that a small circumferential free space is usually sufficient to accommodate these components.
  • the electrical energy required to operate the sensors arranged in the sensor housing and, if necessary, reprocess the electrical signals emanating therefrom, process them and convert them into digital data can be generated directly within the sensor housing in order to be present completely dispense with a line for powering the sensor housing.
  • an induction arrangement is provided in the sensor housing, with which electrical energy is generated during operation of the pump.
  • the induction arrangement has at least one magnet rotatably arranged in the liquid-conducting housing part and at least one arranged in the liquid-free housing part induction coil, such that a current in the coil is induced by the magnet moving past the coil, which is usable for the aforementioned purposes .
  • two or more magnets are arranged, which cooperate with possibly a plurality of induction coils and thus form a kind of electrical generator.

  • the sensor housing is quasi designed as a further passive pump stage, the flow passing through it drives the impeller mounted thereon with the magnets attached thereto, thereby inducing a voltage in the one or more coils or generate a current and thus the sensor within the housing Supply electricity.
  • such a passive pump impeller which is arranged freely rotatable within the sensor housing, and on which at least one magnet is arranged, also form part of a flow meter, wherein then within the liquid-free housing part, an inductive pickup, such as a coil is arranged , so that the speed of the pump impeller can be detected and above the flow rate can be determined.
  • an inductive pickup such as a coil is arranged , so that the speed of the pump impeller can be detected and above the flow rate can be determined.
  • It does not necessarily have a pump impeller rotatably arranged, it can be arranged rotatably a kind of wing, at the end of a magnet sits, which rotates faster or slower depending on the flow rate.
  • the pump can be structurally adapted thereto, then instead of a passive impeller advantageously the drive shaft can be extended into the sensor housing inside and there are provided with a holder, which or the Magnets and is rotated by the drive shaft itself, also an active pump impeller may be provided which carries magnets.
  • any desired pump stage can be designed as a sensor housing by appropriate modification. So it is also conceivable, not just one, but to provide a plurality of sensor housing to monitor, for example, the pressure of each pump stage.
  • the motor is anyway an electrical supply cable, this can be used by appropriate design in a simple manner for data transmission, either by modulating the signal or by providing a further conductor.
