NDJ-1-type
Rotary viscometer
|
| NDJ-1 rotary-type viscometer was used to measure the fluid viscous resistance and liquid kinematic viscosity, widely used in the determination of oil, paints, plastics, food, medicines, cosmetics, adhesives and other fluid viscosity, is to monitor and control of product quality and stable production of precision instruments. |

As shown in Figure 1, apparatus from the synchronous motor at a steady speed of rotation, the connection scale disk, and then driven through the gossamer and the rotor shaft rotation, if the rotor is not subject to the liquid resistance, then the gossamer, pointer and the scale at the same speed disc rotation, pointer pointed out that the readings on the dial "0." Conversely, if the rotor resistance by the liquid viscosity, then the gossamer generate torque, and viscous resistance to contend with the final balance, when connected with the gossamer pointer scale disc reading a certain direction (ie, gossamer torsional angle). Will be readings by the coefficients that have a specific viscosity of the liquid.
Instrument speed from the gear system and the clutch through the speed control knob for variable-speed, sub-fourth gear speed, according to measured need to select. |
