Definitions

  • the present invention relates to a multicellular pump whose hydraulic and mechanical elements are included in a removable cartridge.
  • the present invention relates to a multicellular pump which is mainly characterized by the fact that the hydraulic and mechanical elements of the pump are included in a removable cartridge, on the one hand on the side of the drive shaft, on the other hand on the side of the circuit of the fluid to be pumped.
  • a vertical multicellular pump of the centrifugal type mainly comprising a motor 1 coupled by a device 2 to a hydraulic assembly 3.
  • the pump is mounted on a circuit of pumping fluid mainly comprising a suction line 8 and a discharge line 9.
  • the motor shaft 4 is coupled by means of a coupling device 6 to the shaft 5 of the pump itself.
  • the hydraulic and mechanical elements are contained in several successive stages established along the pump shaft 5.
  • hydraulic element at least one cell like that 7a shown in the figure. It includes a turbine centrifugal 12 and a static part formed by the diffuser 30 and channels 31.
  • mechanical element is meant, for example, the cell 7b which comprises a support 13 and a bearing for guiding the shaft 5, composed of a jacket 14 and d 'a pad 15 secured to the support 13. It is mainly these hydraulic and mechanical elements which are subject to wear or deterioration due to conditions of use which may cause degradation, disturbance or stoppage.
  • the assembly is made in one piece by a plurality of tie rods 17 which attach the lower flange 19 to the rest of the cartridge.
  • the tie rod 17 connects the two end flanges.
  • the cartridge can also take the form of a cartridge 3b, cartridge 3 to which a lantern 2 has been added which allows access to the sealing device 23. It can also be associated with a centering flange 32 of the cartridge 3b on motor 1.
  • the lantern 2 is linked to the upper flange 24 by screws 27 and the centering flange 32 to the lantern 2 by screws 33.
  • the cartridge 3b is therefore mounted on the motor 1 by screws 38.
  • the cartridge To seal the cartridge, it has seals arranged between on the one hand, and on the other hand between the flange 19 and the cartridge body 16.
  • the sealing device 23 makes it possible to avoid pumping up the pumping liquid along the shaft towards the coupling device.
  • the pump is mounted on a pump body of the "in line" type where the suction 8 and discharge 9 ports are aligned and at the same level.
  • the suction pipe 8 of the body pump communicates with a suction flange 10 in communication, at the foot of the shaft 5, with the first hydraulic element 7a.
  • the pumped liquid is sucked up and goes up along the shaft 5 in the succession of stacked cells to finally fall back into an annular channel 11 arranged between the outer casing 16 of the cartridge and the cylindrical surface 26 formed by the stacking of cells .
  • the pumping liquid enters an annular delivery chamber 22 which communicates with the delivery pipe 9.
  • the fixing between the flange 19 and the pump body 20 is carried out by several bolts 18.
  • the coupling device 6 which connects the shaft 5 to the motor shaft 4. Then, in a second step in the case where the cartridge is of the type 3b, the centering flange 32 - motor 1 connections are released by screw operation 33 and lower flange 19 - pump body 20 by screw operation 18. By simple lifting of the motor unit 1 - coupling device 6, it is then possible to release the cartridge 3b which can at that time be sent back for usual repairs or for a simple change of cartridge.
  • the present invention adapts to different forms of pumps, in particular to centrifugal pumps which admit suction and delivery at different levels of the pump.
  • the discharge orifice 9 is returned from the pump body 20 to the upper flange 24. This orifice will be directly in communication with the outlet of the last pumping cell.
  • the annular chamber II at the annular channel and the external envelope 16 are eliminated.
  • the flange 19 and the pump body 20 can be designed to receive a pumping assembly in cartridge or not.
  • This arrangement can be advantageous in the case of low-cost embodiments where the constitution of a pumping unit in cartridge would be too costly.
  • the flange 19 comprises a housing intended to receive the cartridge 3 which has the same diameter D as the housing of the pump housing 20 which carries the bearing.
  • the O-rings 39 and 37 are of the same dimensions.
  • the fixing of the pumping assembly can be ensured without the screws 18 in the absence of the flange 19. In fact, it suffices to rotate the pumping assembly by a determined angle so that the tie rods 17 are screwed directly in place of the screws 18 because the tie rods are in number, dimensions and spacing identical to the screws 18.
