A kind of well head viscosity reduction conveyance conduit based on coupling of the invention, its working principle is that:
By well head pipeline body 1-1 connection crude oil well head pipeline when use, start motor 2-1, the output shaft of motor 2-1 starts
The output shaft of rotation, motor 2-1 drives power belt wheel 2-2 to be rotated centered on own axes, the 2-2 band dynamic pressure of power belt wheel
Power impeller 3 is rotated centered on own axes, provides constant pressure in pressurization conical pipeline 5 when pressure blade wheel 3 rotates
Power；Under constant pressure, the cross-sectional area of pipeline is smaller, faster by the liquid flow velocity of this segment pipe, presses conical pipe
Road 5 plays the role of acceleration to the flow velocity by the crude oil in it, guarantees that the flowing velocity of crude oil can push viscosity reduction cabinet 7-1
The viscosity reduction wheel 8-1 of interior eccentric rotary connection may be rotated, and crude oil is by the acceleration of pressure conical pipeline 5 to viscosity reduction wheel 8-1's
Eccentric position is impacted, and is mixed in the multiple viscosity reduction slot 8-2 being arranged on viscosity reduction wheel 8-1 with viscosity reduction solvent, and push viscosity reduction
