Definitions

  • a pressure regulator at the drilling head which, by a hydraulic device, keeps the pressure close to a predetermined value.
  • the device becomes particularly expensive when the flow rates to be checked are high.
  • This device using mechanical parts moving in the fluid, presents risks of deterioration or malfunction in the presence of sand in the water.
  • the subject of the invention is therefore a motor pump group comprising a pump with discharge pipe, a variable speed drive driving the pump an on-off circuit of the variable speed drive, an analog pressure sensor, detecting the pressure prevailing in the discharge pipe and com controlling the variable speed drive as a function of this pressure and a flow sensor.
  • the flow sensor is arranged to detect a minimum threshold for the flow of the fluid passing through the discharge piping and to control the on-off circuit so as to put it in the on position only when the flow becomes above this threshold.
  • the analog pressure sensor controls Consequently, the variable speed drive and, by decreasing the speed of rotation of the pump, tends to decrease the pressure.
  • the on-off circuit is controlled by the flow sensor, the beats are eliminated.
  • the flow sensor and analog pressure sensor do not have to be set to very strict set points. A drift in time of these devices only results in an insignificant displacement of the operating point of the pump set, without bringing any discomfort to the user.
  • a centrifugal pump 1 has a discharge line 2 comprising a bypass a buffer tank 3.
  • the pump 1 is rotated by a variable speed drive 4.
  • On the discharge line 2 is mounted a sensor flow 5 and an analog pressure sensor 6.
  • the variable speed drive 5 is started or stopped by an on-off circuit 7.
