Definitions

  • a motor for example an electric motor
  • drives a rotary pump for example a propeller pump.
  • the drive by an electric motor can be done by placing the motor on the discharge side, which generally requires a relatively long shaft and poses problems of guiding this shaft, or by placing the motor on the suction side, which raises the problem of the great length of such a motor, especially when the pump must operate in narrow wells.
  • the object of the invention is a very space-saving pumping system, with variable speed, and which can operate by means of a drive by any rotary motor, for example electric motor, diesel engine, gas turbine, etc.
  • the pumping system in which a motor drives a rotary pump is characterized according to the invention, in that the motor is coupled to a volumetric machine with variable displacement, connected by means of hydraulic conduits to at least one volumetric machine with fixed displacement coupled with the rotary pump.
  • a rotary pump such as a propeller pump 1 arranged for example at the bottom of a well is coupled to a volumetric machine with fixed displacement 2, for example a barrel machine with fixed inclination per se known.
  • the pump 1 is connected to a discharge conduit 3 which supplies, for example, an irrigation system represented by a channel 4.
  • the volumetric machine 2 is connected by means of flexible conduits 5 resistant to high pressures to a volumetric machine 6 with displacement variable.
  • the displacement of the machine 6 can be modified by means of a crank 7 which controls the inclination of a barrel body. In place of the crank, it is obviously possible to make the adjustment by a hydraulic piston or by an electric drive system, not shown.
  • the machine 6 can be driven by a rotary motor, for example an electric motor, a diesel engine, a gas turbine or even by means of a suitable transmission, a hand-held or animal-driven motor.
  • the size of the motor 8 no longer has any drawback given the particularly small size of the machine 2 coupled to the pump.
  • the motor 8 can be arranged at a suitable distance from the pump, in particular above a well or on the bank of a channel where it is easy to place, monitor and maintain it.
  • the engine 8 can be arranged, on a single common chassis, in addition the accessories of the hydraulic circuit of the machines 2 and 6 such as oil tank 9, oil filter, cooling exchanger as well as the valves and other control and maintenance devices.
  • a single machine 6 driven by a powerful motor 8 can be connected to several machines 2 each coupled to a pump.
  • the system When the system operates with an internal combustion engine, it is independent of an electrical distribution network and can operate in arid and deserted regions with limited, periodic monitoring either for fuel supply or for regulating the speed depending on the tank level. When this level can change unexpectedly, it is possible to provide automatic control of the pump speed.
  • FIG. 2 shows the pump 1, partially in section. It includes a paddle wheel 10, mounted on a shaft It rotating in bearings 12 and 13.
  • the shaft It is coupled to the volumetric machine with fixed displacement 2.
  • the shaft 11 itself is held in place by bearings stop at the location of the bearing 13 and is enclosed in a bulb 14 also surrounding the coupling 15 with the machine 2.
  • the bulb 14 is held in place and supported by upstream anti-rotation ribs 16 and downstream diffusion ribs 17.
  • a conduit formed through one of the ribs 16 makes it possible to lubricate the bearings at the location of the bearing 13.
  • the lubricant can be the hydraulic fluid itself.
  • the vanes of the wheel 10 are adjustable when the wheel is removed.
