The Measurement Parameters Are Displayed On The Screen Of The Rotary Viscometer

- May 22, 2018 -

After starting the rotary viscometer, it is necessary to detect the zero position. This operation is generally performed without installing the rotor. Then, the inner cylinder of radius R2 is coaxially installed in the outer cylinder of radius R1, and the viscous fluid is filled in between the synchronous cylinder and the synchronous motor. Rotate at a steady speed, successively with the scale disc, and then drive the inner cylinder (ie, the rotor) through the hairspring and the rotary shaft to rotate. The inner cylinder (ie, the rotor) is subjected to a fluid-based viscous moment, and the larger the effect, the longer the hairspring is. The greater the torque produced by the counterbalance, the greater the scale that the pointer indicates on the dial. Multiply the reading by a specific factor to obtain the fluid's dynamic viscosity.

The

The three kinds of conditional viscosity of the rotary viscometer indicate the method and unit are different, but the relationship between the rotary viscometer can be converted by the chart. Simultaneously, the Enn's viscosity and kinematic viscosity can also be converted, which is more convenient and flexible. Viscosity There are many methods for the determination, such as the barrel method, falling ball method, damping vibration method, cup viscometer method, capillary method, etc. For small-viscosity fluids such as water, ethanol, carbon tetrachloride, etc., commonly used capillary viscometer Measurement; For transparent (or translucent) liquids with large viscosity fluids, such as castor oil, transformer oil, engine oil, glycerine, etc., the falling ball method is commonly used; for liquids with viscosity in the range of 0.100 Pa•s, it can also be used for spinning. Determination.
