Description

Technical Field

[0001] The utility model relates to the technical field of viscosity testers, in particular to a viscosity tester. Background Art

[0002] A viscometer is an instrument used to measure the viscosity of liquid or semi-solid substances. It determines the viscosity value by testing the flow behavior of the substance under applied shear force. Viscosity is an important parameter that describes the resistance and internal friction characteristics of a substance and is widely used in many industrial fields. The viscometer is mainly composed of a test container, a rotating device, a temperature control system, a timing and recording system, a data processing and display system, etc.

[0003] When using the existing viscosity measuring instrument, after the liquid to be measured is sucked into the viscometer through the ear washing bulb, it is fixed by the viscosity clamp and then inserted into the constant temperature container. Then, the viscometer is observed to see whether it is vertical. If obvious inclination is observed, the viscosity clamp is adjusted by three adjusting bolts. However, it is difficult to ensure the verticality of the viscometer by manual observation and adjustment. If the viscometer has deviations, the height of the liquid column will change, causing changes in the static pressure difference, resulting in errors in the measurement results, making it difficult to ensure the accuracy of the measurement results. At the same time, when adjusting manually, multiple operations are required to achieve the verticality requirement observed by the naked eye, making the adjustment more troublesome.
