Description

Technical Field

[0001] The utility model relates to the field of experimental detection instruments, in particular to an equidistant installation structure for improving viscosity measurement accuracy. Background Art

[0002] The viscosity measuring stand is the main component for measuring liquid viscosity. It calibrates the viscosity by measuring the time it takes for the liquid to pass a constant distance. The length of the constant distance the liquid passes during measurement directly affects the accuracy of the viscosity. Liquid aspiration - liquid passes the lower fiber position - record the current time - liquid passes the upper fiber position - record the current time - liquid goes up a certain distance - begins to enter the measurement state - liquid flows down by free fall - liquid falls back to the upper fiber position - record the current time - liquid falls back to the lower fiber position - record the current time - the system automatically calculates the viscosity - measurement is completed.

[0003] In the process of viscosity measurement, the time of free fall of liquid is mainly affected by the constant distance of liquid flow, in addition to the viscosity of the liquid itself. However, in the use of the existing viscosity measurement frame, the upper and lower optical fiber measurement points on the measurement frame are unstable and easily displaced, which makes the distance of fluid flow measured by the upper and lower optical fibers inaccurate, seriously affecting the accuracy of fluid viscosity measurement.
