Abstract

The invention relates to an instrument for measuring rheological property and viscosity of fluid, which comprises a mounting plate, a central connecting mechanism arranged on the mounting plate, and ajewelled bearing mechanism and a rotor which are arranged below the installation plate and on the central connecting mechanism in sequence. The instrument also comprises a torque sensor, a torque displacement adjusting mechanism and a bearing mechanism which are arranged above the mounting plate and on the central connecting mechanism in sequence, wherein the bearing mechanism is connected with astepper motor driven by a driving circuit of a high subdivision stepper motor; and the side of the torque senor is provided with a non-contact photoelectric sensor which is connected with a computerprocessor control system. The instrument for measuring the rheological property and the viscosity of the fluid has the advantages of simpler structure, no noise, convenient speed variation and good reliability, ensures the accuracy of the measured viscosity; and the instrument is operated through remote control in a non-contact remote control mode to ensure that the horizontal state of the instrument is influenced by human factors as little as possible, and ensure the accuracy of the measurement.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a fluid rheological property and viscosity measuring instrument. Background technique [0002] Fluid rheological properties and viscosity measuring instrument is a measuring instrument for measuring the rheological properties of various fluids, including measuring the apparent viscosity of Newtonian fluids, non-Newtonian fluids, pseudoplastic fluids, plastic fluids, expansive fluids and other non-Newtonian liquids rheological characteristic curve. [0003] Fluid rheology and viscosity measurements are a method of studying the fluid behavior of substances. It is a directly available fluid property. Product developers can predict and evaluate product phenomena and behaviors based on these fluid properties, and obtain the relationship between rheological data and product behavior. [0004] At present, there are many instruments for measuring viscosity in China. As far as the structure of ...
