The Apparent viscosity is the ratio of shear stress and shear rate applied to the flowing liquid. It is a measure of the internal friction force when the liquid flows under a certain shear stress. It is an important index of engine oil performance evaluation. The service performance of engine oil can be evaluated by measuring its apparent viscosity under different experimental conditions.
The Cold-Cranking Simulator mainly tests the low temperature dynamic viscosity index of the engine oil at -10C to -35C, and the CCS is fully controlled by the computer and the viscosity result is automatically calculated.
* Drive a rotor closely matched with the stator by a DC motor, and fill the gap between the rotor and the stator with samples. The temperature is controlled by the temperature control system, and the motor speed is corrected with standard oil to make it a function of viscosity. Determine the sample viscosity by measuring the rotation speed.
* The rotor and stator system of the instrument uses a thermoelectric temperature control system. Compared with the previous model, the temperature control is improved, the preheating time is reduced, and the measurement accuracy is improved. The compact structure is easy to install and use.
* The Cold-Cranking Simulator Apparent Viscosity Test is suitable for various types of oil laboratories, testing centers, oil modulation institutions and oil manufacturers, for testing or quality control.
