Definitions

  • the invention relates generally to all multi-stage pumps using a very long rotor equipped with blades and, in particular the axial or helical-axial pumps used for pumping two-phase effluents.
  • the pumping of the fluid consisting of a mixture of petroleum and petroleum gases in the context of the exploitation of petroleum deposits, and in particular of deposits at sea.
  • multi-stage double-phase pumps are used which can be associated with a motor unit, in order to allow the high-flow evacuation of a double-phase or multi-phase fluid such as petroleum effluents.
  • these pumps consist of a rotor comprising a main shaft 100 on which impellers 102 are fixed.
  • each impeller 102 is done by means of a key 106 introduced into a slot made for this purpose in the main shaft 100.
  • This precise adjustment is relatively expensive.
  • This assembly allows the rotor to be removable, but by this fact makes the rotor difficult to balance after each change of impellers.
  • the invention aims to remedy this drawback by proposing a multi-stage pump with a different design concerning the rotor.
  • the shaft and the impellers constitute a monobloc assembly produced independently, and each rectifier consists of two half-rings inserted in the annular space separating two impellers and maintained in axial and angular position by washers, the stacking constitutes the main body of the machine.
  • This one-piece structure of the stator allows simple mounting and precise balancing of the entire shaft and the impellers constituting the pump rotor.
  • the central part of the main body consists of at least as many washers as there are stages.
  • the assembly consisting of the shaft and the impellers is manufactured from a single piece in which the impellers are machined.
  • the impellers consist of rings hooped on the shaft.
  • the washers forming the main body are held in place between the inlet and outlet flanges by means of studs connecting these flanges.
  • the shaft is a tube and is terminated at its ends by two pins thus making it possible to mount the free shaft in rotation in the main body by means of bearings.
  • the pump according to the invention is particularly intended for pumping two-phase effluents.
  • the pump according to the invention comprises a pump body 2 which is an assembly, of cylindrical shape over most of its length.
  • the pump rotor consists mainly of a shaft 10 mounted rotating around the longitudinal axis 1 of the body 2. The latter is closed at its ends by flanges (in this case an inlet flange 6 and a flange 20).
  • the shaft 10 is made in the form of a tube. Its two ends consist of two support pins 16 and 18 by means of which the shaft 10 is mounted to rotate in the body 2 by means of two respective bearings 17 and 19.
  • the entire pump is kept assembled by means of studs 4 screwed into a fixing ring 8 and tightened by means of a nut 5 bearing on the inlet flange 6.
  • the pump is advantageously supplemented at one end by a housing consisting of a ring 22 and the fixing ring 8 on the inside diameter of which can bear the external mounting of the bearing 15 and the stop 19 of said end.
  • the pump can be completed with a warhead 24, centered on the axis 1 of the pump. On the inside diameter of this warhead, can bear the outer ring of the bearing 17 corresponding to this end.
  • the driving force is communicated to the fluid by the pump by means of the impellers 12 integral with the shaft 10 and the rectifiers 14, integral with the body 2 and placed in an interposed manner between the impellers 12.
  • the channel created by the interval between the rotor consisting on the one hand of the shaft 10 and the impellers 12 and on the other hand of the stator consisting of the body 2 and the rectifiers 14 delimits the path of the fluid passing through the pump.
  • the outlet flange 20 comprises a cavity 26 placed at the outlet of this channel so as to collect the propelled fluid, thus making it possible to evacuate it by means of an outlet pipe 28.
  • the impellers 12A are mounted on the shaft 10A by obtaining a determined external diameter of the shaft 10 and by boring each thruster 12A to a diameter equal to the external diameter of the shaft 10, so that each impeller 12 can be slidably mounted around the shaft 10 during hot shrinking, the impellers 12 being expanded. The cooling of these ensures their final fixation.
  • This one-piece structure allows the rotor, once balanced, to reach higher speeds than those of a rotor made up of impellers mounted by keying, without generating vibrations. It is noted that speeds of up to 7000 revolutions per minute can be obtained by means of such a hollow shaft with an outside diameter of the order of 240 mm.
  • the mounting of the support pins 16 and 18 can also be obtained by shrinking.
  • the impellers 12B can be an integral part of the shaft 10B. In this case, they are shaped by machining a thick tube whose initial diameter is greater than the external diameter of the impellers 12B.
  • the rotor thus obtained obviously has a one-piece structure having the same advantages as those of the rotor described with reference to FIG. 3A.
  • the body 2 of the pump preferably consists of washers 3 secured by the studs 4.
  • the design of the pump according to the invention provides several advantages of mounting it.
  • this figure represents the lower end of the pump, with the rotor mounted rotating in the last washer 30 in the stack of the body 2, by means of any bearing.
  • the outer ring of the latter is supported on the last washer 30, the inner ring thereof is supported on a sheath 32 hooped on the support pin 16.
  • the warhead 24 acts as a cover for this assembly.
  • the rectifiers 14 each consist of two half-rectifiers 14A and 14B each having the shape of a semicircle. This makes it possible to mount each rectifier by positioning each side of the shaft 10 on each side of these half-rectifiers 14A and 14B and to bring them closer to the shaft 10, as indicated by the two horizontal arrows in this figure. Each rectifier is thus interposed between two impellers 12. This maneuver is better illustrated by FIG. 5 where only the half-rectifiers 14A and 14B are represented in the position which allows them to be inserted between two impellers 12. This figure also each represents washers 3 constituting the body 2 of the pump.
  • the structure of the rotor makes it possible to reach speeds equal to 7000 revolutions per minute without exceeding the maximum critical speed of this rotor with twelve to fifteen stages, which makes the pump according to the invention particularly well suited for pumping oil presenting itself in the form of a liquid phase and a gaseous phase, with significant flow rates.
