Abstract

The invention discloses an electroosmosis principle based liquid dynamic viscosity measuring platform. The electroosmosis principle based liquid dynamic viscosity measuring platform comprises a box body, two adjustable infrared light sources, a first power supply polar plate, a second power supply polar plate, an experimental bracket and electroosmosis tubes, wherein the box body is of a rectangular box body; a movable box cover is arranged above the box body; the experimental bracket is arranged on the middle position of the box body along the long sides; the electroosmosis tubes are supported on the upper part of the experimental bracket; the two adjustable infrared light sources are arranged at front and rear sides of the experimental bracket along the long sides; the first power supplypolar plate and the second power supply polar plate are separately arranged at left and right sides of the experimental bracket; the two adjustable infrared light sources, the first power supply polar plate and the second power supply polar plate are connected with guide wires, and the guide wires are guided to the outside of the box body through wire holes in the box sides; the experimental bracket consists of two bracket pins and a scale bar, wherein semicircular notches are formed in the bracket pins; patch thermocouples are adhered inside the semicircular notches; and the electroosmosis tubes are arranged on the patch thermocouples in the semicircular notches. The electroosmosis principle based liquid dynamic viscosity measuring platform is simple in structure, is convenient to operate, is high in accuracy, and can give the characteristic that the liquid viscosity changes along with time.

Description

technical field [0001] The invention belongs to the field of fluid measurement, and relates to a fluid dynamic viscosity measurement platform, in particular to a liquid dynamic viscosity measurement platform based on the principle of electroosmosis. Background technique [0002] Viscosity is one of the important physical properties of fluids, which reflects the characteristics of liquid flow behavior and is an important standard feature in food industry, petroleum industry and other industries. Measuring fluid viscosity and fluidity is of great significance in industrial production and basic science research. At present, the methods for measuring fluid viscosity include capillary method, sedimentation method, rotation method, vibration method and so on. In many industrial enterprises, different types of viscous liquids used in different occasions have different requirements for viscosity grades. Some can be measured at room temperature, but some require high temperature me...
