Background technology
Viscosity is the physical quantity for characterizing fluid viscosity degree, be whether can be up to standard to liquid important references mark
Standard, viscosity have vital effect in many industrial departments and scientific research.Whether the product that plant produced comes out
Standard can be reached, whether the performance of product can meet regulation, these be required for this important index of viscosity come to liquid into
Row evaluation, therefore the accuracy of viscosity measurement plays an important roll industrial expansion.It particularly will to viscosity criterion at some
The industry that comparison is high, such as the industries such as petrochemical industry, metallurgy, medicine, food are asked, for some liquid, only need to measure its
Viscosity, it is possible to the which whether quality and performance for evaluating fluid product comply with standard.
There are five types of viscosity measurement field master measuring methods to be used, be respectively viscosity agar diffusion method, vibratory drilling method, Constructional Elements Using Falling Methods,
Blood capillary tube method and rotary process.Frequency of use is preferably at most blood capillary tube method and rotary process in these types of measuring method.In industry
What we were usually used when needing to measure viscosity in production is revolving viscosimeter.This viscosity has the advantages of very much, such as
Measurement is convenient, application method is simple, the accuracy of measurement is high.This viscosimeter is when measuring viscosity by adjusting rotating speed
It completes to the fluid viscosity under different shearings rate.
Six fast rotational viscometers are the common instruments of rotary process viscosimetric.The test philosophy of rotary process viscosimetric is to pass through electricity
Machine drives rotor to be rotated in testing liquid, since the speed of rotation that rotor is influenced be subject to viscous force in liquid is set than motor
Fixed is small, and the elastic element being so connected with rotor has power opposite to the direction of rotation and generates.Ignoring fluid to be measured outside
Suffered viscous force, in the case of being seen as zero, can obtain measured object by equation below on cylinder inner wall and bottom
Viscosity：
In formula：η represents the dynamic viscosity of fluid；M represents moment of face (equal with viscous moment)；H represents that rotor is immersed in
Height in test solution；ω represents the angular speed of rotor rotation；R1Represent rotor radius；R2Represent outer barrel radius.
By the above formula, angular speed is set in measurement, and radius R and height h can be measured directly
Out, it is known quantity, it is desirable to acquire the viscosity of liquid, it is only necessary to know that torque M.Due to extensive use in the industry,
People are more deep for its research, while very many improvement have also been done to rotary viscosimeter, such as add in single
Piece machine controls, and data are acquired using sensor, are in real time shown measurement data by liquid crystal display；It realizes
On-line measurement and off-line measurement two ways.These are all changed the measurement of viscosimeter, make the precision higher of measurement, are glued
Degree meter is also provided with more functions, uses also enhanced convenience.The scope of application of rotary viscosimeter is wider, the life to industry
Production has very big facilitation.
However, the shortcomings that six fast rotational viscometer viscosimetrics also have it, for example equipment volume is bigger, the structure ratio of design
It is more complicated, cost is higher.Furthermore, it is possible to as can be seen that viscous in six speed rotations from above-mentioned viscosity calculations formulation process
Measured object is ignored in the viscous force that outer tube inner wall is subject to when degree measurement examination measured object viscosity.However, in actual survey
This viscous force is existing in the case of examination, it, which is ignored, can influence test result, therefore the six fast rotational viscometer precision is not
Height, existing can be with improved place.
