The inventive principle of the present invention is as follows：
(1) slurry coefficient of viscosity expression
The internal diameter of container cartridge and the external diameter of hollow drum have directly impact on certainty of measurement.Container cartridge position holds tested slurry
The device of body, container cartridge is maintained static, and the internal diameter of container cartridge is R2, hollow drum is the hollow thin-wall circle coaxial with container cartridge
Cylinder, the external diameter of hollow drum is R1, it is highly L.
During measurement slurry viscosity, hollow drum is immersed in the container cartridge for holding slurry, hollow drum passes through first
Rigid rotating support shaft is connected in lower rotation dish, when upper rotation dish, elastic hairspring, lower rotation dish are rotated up to poised state
When, micro synchronous motor can drive hollow drum to rotate in slurry with constant angular velocity vector Ω.
Container cartridge is maintained static, and container cartridge inwall is fricton-tight with slurry, and the slurry angular velocity of rotation at chamber wall is 0, empty
The angular velocity of rotation of heart rotating cylinder is Ω, under the viscosity effect for disregarding upper and lower end parts, when the slurry in container cartridge is with hollow drum
When rotation reaches poised state, moment of elasticity M is balanced with viscous moment on elastic hairspring, and the coefficient of viscosity of slurry is：
In formula, η is the coefficient of viscosity between liquid layer, and the kinematic viscosity of slurry is η/g.
According to above formula, the coefficient of viscosity η of slurry is M, L, Ω, R1、R2Function, when change some of which parameter when, can
So that measurement apparatus to be fabricated to the multrirange test device of measurable different range η and different accuracy.
Above formula is converted, and introduces new variable τ, D, the coefficient of viscosity of slurry is：
Wherein,It is the shear stress of drum surface,It is the shearing of drum surface.
When moment of elasticity M is constant, the physical dimension of τ and rotating cylinderIt is inversely proportional to, L or R1Less, τ-value is bigger, then survey
The viscosity scopes of examination slurry are bigger.
Elastic hairspring is the important component part of sensing device, and elastic hairspring two ends are fixed and the number of turns of elastic hairspring is more than
5 circles, then can ignore the counteracting force P and R of fixing point, act on elastic hairspring only in end moment+M and fixing end
Torque-M.
The corner of elastic hairspring the inner fixing end is：
φ=Ml/EI=12Ml/Ebt3
In formula, l is the length of elastic hairspring, and E is elastic modelling quantity, and I is hairspring section to parallel to the geometry of shaft axis
The moment of inertia, flakiness ratio b/t of general square-section<10.
The corner of the upper and lower fixing end of elastic hairspring, that is, the angle for descending the delayed upper rotation dish of rotation dish is exactly viscous suffered by rotating cylinder
The reflection on year-on-year basis of torque M.
(2) signals collecting principle
When micro synchronous motor drives upper turn disc, elastic hairspring drives lower turn disc；Because of slurry pair
The viscous effect of hollow drum appearance, the rotational angular velocity of lower rotation dish is inconsistent with the rotational angular velocity of upper rotation dish；It is miniature
Sometime point after synchronous motor work, under the balanced action of elastic hairspring moment of elasticity, lower rotation dish is delayed certain
With the stable synchronous rotary of upper rotation dish after angle, but lower rotation dish is inconsistent with the angular displacement of upper rotation dish, in elastic hairspring
Moment M is present；From overhead view, lower rotation dish can change with the breach intersection of upper rotation dish.
From overhead view, instantly rotation dish exists between breach, i.e. light emitting diode and light sensitive diode with upper rotation dish
Without blocking for upper and lower rotation dish, diode current flow；Instantly rotation dish is closed with upper rotation dish, and diode disconnects.
Through the process of pulse signal transducer, during diode current flow, signal is designated as B=1；When diode disconnects, signal
It is designated as B=0.
When moment of elasticity M=0, notch opening angle α=0 between upper rotation dish and lower rotation dish, B=0；Work as moment of elasticity
M>Notch opening angle α when 0, between upper rotation dish and lower rotation dish>0, B=1, persistent period and the notch opening angle α of pulse signal
Size be directly proportional, the as initial data of viscosity.
The initial data that pulse signal transducer is generated, is input into slurry viscosity coefficient η meters after being gathered by data processing equipment
Formula is calculated, the viscous moment that the viscous effect that rotating cylinder is subject to is produced in elastic hairspring is converted into the substrate slurry motion of standard
Viscosity.
It is defeated data to be displayed in after the kinematic viscosity value that data processing equipment process is obtained is exported by data processing equipment
Go out on device；
Complete serosity viscosity intelligent measure.
