Different helical angles (tangential direction of spiral and horizontal angle) and different passage lengths vertically downward, adapt to different hydrometries, simultaneously erect passage vertically downward in order to what same fluid used different helical angles or different length, realize different mensuration.Devise the series helix shape passage with different helical angle to select for during different fluid circulating load.In order to prevent the sedimentation of particle, suitable different pressures and the mensuration of suspension adapting to different spiral angles, the hypomere of Ring-cylindrical is preferably detachably connectable.The remaining spiral type influent stream passage with dispensing orifice, the epimere that below dispensing orifice, UNICOM vertically downward erects passage, can individually be referred to as spiral type influent stream passage.Detachably connectable Ring-cylindrical hypomere and the connection of epimere can be Flange joint or bonding or screw thread socket or transition socket.Ring-cylindrical hypomere and perpendicular passage can individually be referred to as Ring-cylindrical collimator.The Ring-cylindrical collimator so formed, below spiral type influent stream passage, is a circular cylindrical fluid collimator, and its effect is to eliminate the tangential of circulation of fluid and Radial Flow further.The annular width of Ring-cylindrical collimator is equal with measurement space width, has the perpendicular passage of arranged distribution, each passage to dock completely with each passage below the dispensing orifice of spiral type influent stream passage along annulus.The fluid flowed out in collimator duct only has the speed of vertical direction.Spiral type influent stream passage and perpendicular passage with dispensing orifice are made up of transparent material, and whether the equilibrium assignment effect that can observe spirality channel from outside completes.
Spiral type influent stream passage, Ring-cylindrical collimator, flow graph urceolus arrange from top to bottom, are preferably connected by ring flange between any two.Leaving 1mm gap between Ring-cylindrical collimator inner wall lower edge and flow graph rotor, both ensured that the rotation of rotor was interference-free, and made again the circulation of fluid overwhelming majority enter measurement space, the fluid flowing to rotor upper end on a small quantity from gap will not impact.Theoretical research proves, fluid is when drum-type rheometer interval of internal and external tube internal circulation flow, if meeting following condition:
(1) circulation of fluid enters measurement space with vertical direction, i.e. in addition to axial velocity, there is not the velocity component of radial direction and direction of rotation；
(2) equiblibrium mass distribution on the fluid of the measurement space whole ring section between inside and outside cylinder it is recycled into；
Then can ensure that flow graph according to original principle work under conditions of fluid circulates, and can not change computation model.
Beneficial effects of the present invention: use " the circulation of fluid collimation distributor " of the present invention, when using drum-type rheometer to measure free settling suspension flow variable element, can make circulation of fluid with vertical direction enter measurement space and enter time equiblibrium mass distribution in ring section, so that flow graph is by original operation principle and computation model running, it is not required to any correction.
