Definitions
- the present invention relates to the field of pumps, in particular for high pressure and high flow pumping, in particular for drilling operations ranging from a few hundred meters to a few kilometers.
- crankshaft pumps are the most widespread in all sectors of the industry: capital goods, oil, gas and agri-food industries, the automotive sector, construction (heating, wells, air conditioning, water pumps, etc.) and more specifically for the treatment of water and waste (water and sanitation network).
- pumps of this type have a limited number of pistons (of the order of 5), because of the limitations of the size of the crankshaft which is also subject to high stresses and sudden changes in pressure that can intervene in repression.
- These pumps therefore have limits in terms of power, torque pressure / flow (limited by "water hammer” generated by the sinusoidal pressure of the crankshaft), weight, yield and service life. In addition, they do not allow to have a variable displacement and therefore lack flexibility of use.
- the fixed-barrel pumps (FIG. 1): in this pump configuration 1, where the barrel is fixed, it is the inclined plate 2 which rotates (driven by the shaft 5) in order to generate the movement of the pistons 3 in their 4.
- the connection between the pistons 3 and the plate 2 is then provided by rotatable pads which rub on the plate 2.
- the advantage here is to have a very low inertia of rotating parts.
- the rotary barrel pumps (FIG. 2): within the pump 1, the plate 2 is fixed and the barrel 6 carrying the pistons 3 is rotated, thus ensuring the movement of the pistons 3 in their shirts 4.
- the piston 3 - plate 2 connection is provided in the same way as for the first configuration.
- the advantage of this architecture is that it can easily make the adjustable tray tilt and thus have the possibility of variable displacement.
- the inertia of the rotating parts increases significantly since the barrel and the set of pistons are rotated.
- Barrel pumps with swash plate the barrel is fixed in this architecture and we have two plates, a first inclined plate is rotating and transfers to the second plate only the oscillation movement.
- a first inclined plate is rotating and transfers to the second plate only the oscillation movement.
- the number and the diameter of the pistons, as well as the inclination of the plate condition the desired flow rate for the pump.
- the pistons are in turn under high pressure, then at atmospheric pressure, so that the barrel / piston assembly prints a load on the plate whose module is spatially heterogeneous. Indeed, with respect to the intake pipe (atmospheric pressure) the load is relatively low, while compared to the discharge pipe, the load is maximum.
- the present invention relates to a double barrel pump, double tray and double inlet / discharge, the elements of each of the barrel-tray-inlet-discharge assembly being distributed along a drive shaft so as to to reduce the stresses on the plates and the different mechanical connections, and thus to reduce the risks of rupture.

- the trays of each set may be substantially disk-shaped. However, the trays can have any shape.

- the intake pipe and the discharge pipe of each of the pumping assemblies can be placed symmetrically with respect to the axis of the drive shaft, or in other words the inlet and discharge pipes of one set face each other with respect to the drive shaft.

- the turntable transmits only the oscillation movement to the swash plate and does not transmit the rotational movement.
- the pistons of each of the compression chambers of a given pumping assembly are driven by the oscillating plate of this assembly, for example by means of connecting rods (the rods connect, by means of ball joints, the oscillating plate and the pistons so as to transform the oscillation movement into translational motion of the pistons), and the translation of the pistons within the compression chambers realize the pumping of the fluid.
- the rotary plate can be driven by the drive shaft by means of a finger ball joint, the position of the finger ball joint determining the inclination of the two plates (rotary and oscillating) by relation to the drive shaft.
