A fully automatic intelligent liquid dynamic viscosity measurement device and method

Abstract

The invention provides a fully automatic intelligent liquid dynamic viscosity measurement device and method, which belong to the field of experimental instruments, comprising: a viscosity measurement unit including a rotational viscometer and a viscometer adjustment frame, the rotational viscometer is used to measure the viscosity value of the liquid to be measured, The viscometer adjustment frame drives the rotary viscometer to achieve lifting, translation and rotation movements; the constant temperature water bath unit includes a preheating constant temperature water bath and a measuring constant temperature water bath, both of which are used to control the temperature of the liquid to be tested; the sample transfer unit is used for The sample cup containing the liquid to be measured is reciprocally clamped and released between the two water baths; the cleaning unit is used to clean the rotor of the rotational viscometer, and the drying unit is used to dry the cleaned rotor; the control unit is used to control The operation of each unit; the data acquisition and analysis unit is used to collect the viscosity data measured by the rotational viscometer, and collect and analyze the viscosity data. The device integrates artificial intelligence and automation, and has high measurement accuracy and efficiency.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, in particular to a fully automatic intelligent liquid dynamic viscosity measuring device and method. Background technique [0002] In production and scientific research, it is often necessary to measure the dynamic viscosity of liquids and fluids. A rotational viscometer is a commonly used measuring instrument. ) to measure the dynamic viscosity. [0003] The market situation and technical status of rotational viscometers are as follows: 1. There are many manufacturers, brands and models of rotational viscometers at home and abroad. On the whole, all kinds of rotational viscometers can measure a large range (1mPa·s~20×10 6 mPa·s). However, these products sold on the market have the following limitations: 1. The main unit of the viscometer and the temperature control device, rotor cleaning and drying devices do not form a matching system, which causes certain difficulties in the...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of the host, it is easy to cause the screw to slip off and the positioning is difficult

3. When placing the sample cup in the constant temperature water bath, place it manually, because the manual operation is not stable, it will often cause liquid overflow

If the liquid is a complex component such as crude oil, if it overflows into the water, it will cause a large pollution accident that is difficult to clean.

4. It is necessary to observe the appropriate range of temperature with the naked eye before the test, and to identify the test data and test time with the naked eye during the test, which is difficult and lacks precision in operation

5. In the detection process, only relying on the instrument's own program to determine the results may input worthless and meaningless data, so the accuracy is not high enough for specific sample performance

6. Since all the above-mentioned links need to be done manually, the work efficiency is relatively low
