Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, in particular to a viscosity tester. Background Art

[0002] A viscosity tester is an instrument for measuring the viscosity of a liquid, which is driven by a motor to drive a rotor to rotate at a constant speed through speed change. When the rotor rotates in the liquid, the liquid will generate a viscosity torque acting on the rotor. The greater the viscosity of the liquid, the greater the viscous torque; conversely, the smaller the viscosity of the liquid, the smaller the viscous torque. The viscous torque acting on the rotor is detected by a sensor and the viscosity of the measured liquid is obtained after being processed by a computer. When performing viscosity detection, first place an electric heating furnace below the motor rotor, and then adjust the positions of the electric heating furnace and the rotor so that the rotor extends into the heating tank of the electric heating furnace, and then start the motor for detection. In order to save test materials, the notch of the heating tank is generally small, so when aligning the rotor with the notch of the heating tank, the position of the electric heating furnace needs to be adjusted multiple times to align the rotor with the notch of the heating tank, so the operation is rather troublesome.
