NDJ-79

Rotational viscometer

Introduction

Rotational Viscometer NDJ-79 is a precision instrument for measuring the absolute viscosity of various Newtonian liquids and the apparent viscosity of non-Newtonian liquids. If used with a specific rotor, it can also determine the rheological properties of non-Newtonian liquids. It has the advantages of convenient use, stable performance, simple maintenance, wide range of measuring viscosity (1~1×1000000mpa.s), and can be connected to external equipment such as high-low temperature constant temperature baths to control the temperature of the tested sample and increase the viscosity value of the measured liquid. The accuracy of the test sample liquid is 15-70ml, which can effectively save the sample volume.

Applications

The rotary viscometer is suitable for measuring the viscosity of various fluids such as oil, paint, ink, coating, plastic, slurry, rubber, latex, detergent, resin, condensed milk, cream, medicine and cosmetics. , electromechanical, pharmaceutical, food, light industry, construction, and other industries, as well as universities, scientific research units, laboratories of military industry departments, and analysis rooms.

Principle

The instrument is driven by a miniature synchronous motor, which rotates at a constant speed of 750 r/min, and is hardly affected by changes in load and power supply Voltage. The housing of the motor is installed in a suspended manner. It drives the rotating cylinder to rotate through the rotating shaft. When the rotating cylinder rotates in the liquid to be measured, it receives the action of viscous resistance, thereby generating a reaction force that deflects the motor housing. The motor housing and the two The metal balance spring installed one forward and one reverse is connected, and the rotation of the case causes the balance spring to generate torque. When the torque of the balance spring and the viscous resistance torque are balanced, the pointer connected to the motor case will point out a certain value on the dial, which is proportional to the viscous resistance of the drum, so the scale reading is multiplied by the rotation The barrel factor represents the magnitude of the dynamic viscosity.
