Full-automatic intelligent hydrodynamic viscosity measurement device and method

Abstract

The invention provides a full-automatic intelligent liquid dynamic viscosity measurement device and method, and belongs to the field of experimental instruments. The full-automatic intelligent liquiddynamic viscosity measurement device comprises a viscosity measurement unit which comprises a rotary viscometer and a viscometer adjusting frame, wherein the rotary viscometer is used for measurementthe viscosity value of the measured liquid, and the viscometer adjusting frame drives the rotary viscometer to lift, translate and rotate; a constant-temperature water bath unit which comprises a preheating constant-temperature water bath kettle and a measurement constant-temperature water bath kettle, wherein the two water bath kettles are used for controlling the temperature of the measured liquid; a sample receiving and sending unit which is used for clamping and releasing a sample cup filled with the measured liquid between the two water bath kettles in a reciprocating manner; a cleaning unit which is used for cleaning a rotor of the rotary viscometer; a drying unit which is used for drying the cleaned rotor; a control unit which is used for controlling the operation of each unit; anda data acquisition and analysis unit which is used for acquiring the viscosity data measured by the rotary viscometer and acquiring and analyzing the viscosity data. The device integrates the artificial intelligence and the automation as one, and is high in measurement precision and efficiency.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, and in particular relates 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. Rotational viscometer is a commonly used measuring instrument, which can measure Newtonian fluids and non-Newtonian fluids (including plastic fluids, pseudoplastic fluids and expansion fluids, etc.) ) to measure the dynamic viscosity. [0003] The market situation and technical status of rotational viscometers are as follows: 1. At present, there are many manufacturers, brands and models of rotational viscometers at home and abroad. Generally speaking, all kinds of rotational viscometers can measure a large range (1mPa·s~20×10 6 mPa·s) viscosity value. However, these products sold on the market have the following limitatio...

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
