Description

Patent application

The pump is used to transport fluids with high viscosity, such as hydrocarbons, over long distances. An example of this is transporting oil from Subsea installations offshore to onshore facilities.

When several units with vanes are assembled together, a continuous screw pump (20) is formed where electricity is transferred to the stator / rotor (4-7) via current conductors in the shaft (10) which is stored (9) in the center of the unit (11). Electricity and signal can be transferred via contact with current conductors in the cover (14,15) to the modules (3) with electronics. The grooves in the cover (14,15) will also lock the units (11) together when several units (11) are assembled together by screwing the shafts into each other (12,13). Unit with vanes (16) is mounted on unit (11). Several units with vanes are then screwed into each other and the vanes become connected (20). Shaft (21) is then mounted inside a unit (24) which has current conductors for the supply of electricity to the units with vanes. The pipes (22) on the outside of the vanes are screwed onto the unit (24). A flange can also be used between the unit (24) and the pipes (22). Electricity is connected to the contact on the outside of the unit (24). This can be done at the ends, or on each unit (24) in the series.

Pump assembled together (fig.14).

Technical description:

Fig 1 is seen as a cross-section seen from the side. Unit (1) which consists of pipes (2) where modules / units (3) are threaded onto the pipe and locked against grooves in the pipe. Through bolts lock the modules together on the pipe.

The pipe (2) may have current conductors that conduct current into the modules (3). The modules are used for converting current, signal control or other technology.

Fig 2 is seen as a cross-section seen from the side. Two units (1) are placed against each other and mounted on the rotor / stator. The rotor / stator is stored with ball bearings (4) on both units (1). The shaft is fixed in the center of the rotor / stator (5) Current conductors (5) in the stator / rotor transfer current from the shaft into the coil (6). The current / electricity can also be fed into the module units and transformed before it is used against the stator / rotor. Brushes are used between the stator / rotor and the module units if this is done. Current conductors can also be used instead of brushes.

Magnets / current conductors (7) are fixed between both module units (1).

Fig 3 is seen as a cross-section seen from the side. Shaft with current conductor (8) is screwed onto the shaft part (10) with current conductors that conduct the current / electricity into the stator / rotor (5) and on to the coil (6). The shaft is supported at both ends (9) with ball bearings. The cylindrical cover (11) is threaded onto the unit and locked with bolts to the module units (1). The cover has grooves on the top and bottom (14, 15) which are used when several units are assembled together. These tracks (14,15) can also be used as contacts to transfer power / electricity / signal between several motor units (11) which are assembled together. On the sides of the cover there are grooves that are used to enter the unit with vanes (16). Threads in the shaft (12,13) which are used to screw together several motor units (11). Figs 4 and 5 show the unit seen from the side. Shaft part (8) with current conductor in the center is screwed onto shaft part (10) with current conductors on the outside. Electricity that is conducted through the shaft will be transferred to the stator / rotor via shaft part 10 with external current conductors. Fig 6 shows the figure seen from the side, above from below. Two motor units (11) showing the top and bottom of the unit. Axle in the center where threads (12,13) are used to screw several units together. Tracks (14) which can be used as contacts that fit into the tracks (15). The tracks (14,15) ensure that the motor units are locked together so that they have the same rotation around their own axis. Point 19 is discussed under figures 9 and 10. Figures 7 and 8 show the units seen from the side. Motor unit (11) with groove along the side is placed into groove in unit with vanes (16). Unit with vanes is locked to motor unit with screws (17). Figs 9 and 10 show the figure seen from the side. The figures show how two units with vanes are assembled together with the shafts being screwed into each other. Point 19 in figure 6 shows the rotation of the tracks (14,15) from the upper side to the lower side of the unit (11). This rotation / angle corresponds to the rotation of the vane (18) which is mounted on the unit. This means that the blades will overlap each other (20) when several units are assembled together. Figs 11 and 12 show the figures from the side. Unit (24) is used between the units with vanes to lock the shaft (21) and to screw in the pipes (25) which are on the outside of the vanes. Threads in shaft (21) are screwed into unit (24) from both sides. Contact is then achieved between the current conductors (21) in the shafts inside the unit (24). Electricity is supplied to the units with vanes via contact with current conductors on the outside of the unit (24). Current conductors from the contact pass through the grooves/blades (26) in the unit (24) and come into contact with current conductors in the shaft (21). Fig 13 is seen from the side and above from below. Picture shows how the units (24) are used between the pipes (22) and with the pump inside.

Fig 14 shows the unit from the side screwed together.
