Definitions

  • the present invention refers to a pump with progressive vortex system.
  • the current pump systems are composed of the so-called helical progressive cavity pumps. These pumps have a rubber stator with a single cavity. This cavity has a helical shape generated by two 180°-dephased circumferences (double entry) that are displaced with a determined pace along the central stator shaft. The helical rotor as it rotates inside this cavity has an inevitable radial displacement. Therefore, these pumps need a compensation system in the rotation movement transmission, generally performed by a cardan shaft. Although the problem in the transmission is solved, these pumps have the inconveniences of having great lengths, in function of the cardan, and of working with an undesirable vibration. This vibration most of the time hinders these equipments to work with rotations greater than 500 rpm.
  • Another system currently used is based on the axial flow of the fluid through multiple longitudinal cavities and it is a combination of peristaltic pump and helical progressive cavity pump.
  • These longitudinal cavities are formed by flexible tubes (hoses) displaced circularly inside a steel pipe.
  • a helical rotor rotates in the central space of this assembly compressing the hoses against the steel pipe.
  • the fluid is pumped longitudinally inside the hoses.
  • the problem of this pumping system is that between the hoses and the rotor and also between themselves results a useless empty spaces, which hinders the reduction of the pump dimensions.
  • PI 0403685-9 proposes a pump with centered helical rotor, the persisting problem in this concept is that the stator is made of rubber.
  • the composition components of the petroleum end up attacking the rubber, aggregating or removing some component of its composition. Besides this inconvenience the helical progressive cavity pumps cannot work at elevated temperatures, since the rubber deteriorates.
  • the objective of the present invention is to provide a progressive vortex pump, aiming at solving the problems encountered in the rubber component, vibrations and pump size.
  • the progressive vortex pump of the present invention has multiple stages, works at the center, eliminating totally system vibration, all components are metallic, which can work at very elevated temperatures.
  • FIG. 1 represents a front view of a PCP pump ( 11 ) installed in a well
  • FIG. 2 represents a front view of a progressive vortex pump ( 21 ) installed in a well;
  • FIG. 3 represents a front view of a PCP pump ( 11 ) sectioned longitudinally, where we can observe all its internal components;
  • FIG. 4 represents a front view of a vortex pump ( 21 ) sectioned longitudinally, where we can observe all its internal components;
  • FIGS. 5, 6 and 7 represent front views of the progressive vortex pump ( 21 );
  • FIG. 8 represents a detail of FIG. 7 where we can observe the vortex ( 71 ) operation (the direction of fluid rotation within the stage can be observed);
  • FIG. 9 represents a detail of FIG. 8 where we can observe the passage of the fluid from one stage to another ( 81 );
  • FIG. 10 represents a blown out view of the vortex pump ( 21 ) components
  • FIG. 11 represents a detail of FIG. 10 where we can observe the 3 basic components of the vortex pump ( 21 ) (diffuser ( 111 ), rotor ( 112 ), stator ( 113 )).
  • All vortex pump ( 21 ) components are metallic, this way they can work at high temperatures without damaging any component of the vortex pump ( 21 ).
  • the difference of the progressive vortex pump ( 21 ) in relation to those already existing in the market is the number of stages, because due to the geometry of the parts, diffuser ( 111 ), rotor ( 112 ) and stator ( 113 ), we can mount the number of stages that we may wish.
  • the mounting of the progressive vortex pump starts with the shaft, where the rings (sliding, graphite, sealing), bearings, pump pipe, valve, diffuser ( 111 ), rotor ( 112 ) and stator ( 113 ) are assembled.
  • the diffuser ( 111 ), rotor ( 112 ) and stator ( 113 ) assembly forms a stage and can be mounted in accordance with the number of stages needed to reach a particular pressure for the application in which the pump will be used, where there is no limit to the number of stages.
  • the fluid enters through an existing opening in the diffuser ( 111 ), then passes through an opening in the stator ( 113 ) and when the fluid arrives at the rotor ( 112 ), in each one of the rotor ( 112 ) blades the fluid performs a vortex movement (direction of fluid rotation).
  • the progressive vortex pump ( 21 ) can be used in petroleum wells, which is installed in the drilling. Since all components are metallic, the pump ( 21 ) can work under temperatures higher than 300° C. without harming any of its components, or reducing its capacity. Since this pump ( 21 ) has the shaft at the center, the pump works without generating vibrations, which increases the useful life of the pump ( 21 ) and it can even work at high rotations without any damage.
