Definitions

  • the invention relates to a hydraulic submersible piston pump with hydrodhynamic transmission.
  • hydraulic piston pumps with reciprocating movement, with single or double effect, with one or more cylinders, with disc or plunger piston, simple or differential, with manual or motor control, currently known provide that the rod the piston is actuated by means of a mechanical transmission which can be of the pendulum type, with crankshaft or oblique disc or rotary seat, etc.
  • the range and the height of elevation of these pumps depend on the control force adopted, the dimension and the number of cylinders, the number of cycles per minute, the number of stages, the temperature of the liquid and other factors.
  • the suction height is limited by the barometric pressure and by the passive resistances to a maximum of approximately 7-8 m while the range in volume of these pumps is limited to a maximum of around 500-600 l / h.
  • the object of the present invention is to increase the elevation height and the range of said hydraulic piston pumps using a low power that of control, such as manual control.
  • said pump is distinguished by its high performance, that is to say a height of elevation and a range far greater than those obtained, until now, at the same force as the control, and by the simplicity of its operation.
  • Figure 1 shows the overall view, in vertical section, of a submerged, double-acting piston pump, produced in accordance with the present invention
  • Figure 2 shows the overall view, in vertical section, of a submerged piston pump, single effect, according to the invention.
  • the pump shown in Figure 1 of the accompanying drawings comprises: at the bottom of a vertical probe 1, a vertical pump body 2 with piston, which is open at its ends and thus communicates with two manifolds 21 correspondents, which are provided with two stop valves 22-23, respectively of inlet / outlet of the liquid, in phase of pressure / aspiration of the piston 20; a pipe 3 for sending the liquid to the surface, connected to said collectors 21 downstream of the valves 23; machines for the hydrodynamic transmission of the movement to the piston 20 of the pump 2 with a first operating cylinder 4, fixed at the top of the pump 2 and in the axis of the latter, with its own piston 40 operating in tandem with the piston 20 of the pump 2, and with a second surface motor cylinder 5, connected to the first cylinder 4 by two tubes 6 and with liquid in saturation so that, at the down / up stroke of the piston 50 of the cylinder 5 corresponds to the down / up stroke of the piston 40 of the cylinder 4, the diameters of the cylinders 4-5, being differentiated with
  • the pump comprises: a vertical probe 1, at the bottom of which is fixed, coaxially, the pump 2, the cylinder of which is open in its lower part and closed in its upper part and whose piston 20 is provided with a valve 22 with valve, making it possible to block the liquid in the pressure phase; a pipe 3 for sending the liquid to the surface, located inside the probe 1, connected to the top of the pump 2 and provided with a retention valve 23 in the aspiration phase; devices for the hydrodynamic transmission of the movement of the piston 20 of the pump 2, similar to those already described for the pump in FIG. 1.
  • the pump operates with a single effect. / /
