Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of viscosimeter, concretely to a viscosimeter. BACKGROUND

[0002] The viscosimeter is an instrument for measuring the viscosity of a fluid, and the viscosity is a physical quantity representing internal friction of the fluid when flowing, and is the ability of the fluid to resist deformation, and is an important index for identifying certain finished products or semi-finished products.

[0003] The common viscosity generally adopts a container to contain the liquid to be measured, a temperature control device to keep the temperature of the liquid to be measured stable, a rotating motion device to generate rotating motion and measure the viscosity of the fluid, and a display part to display the measurement result.

[0004] In order to detect the fluid more quickly, more containers are used to store the fluid to be detected, and after the fluid detection is completed, the container is taken out and placed in the container to be detected. However, during the measurement of the rotary viscosimeter, the sample container has an influence on the measurement value, especially when measuring the relative viscosity, the size and shape of the container will affect the test result. If the viscosity of the sample is large, a larger diameter rotor and a corresponding sample container may need to be used to ensure that the rotor can rotate normally in the fluid and accurately measure the viscosity of the fluid. After replacing the containers of different sizes, the container and the rotary detector are offset, which requires the fixed component to be moved and the corresponding fixed component to be replaced for installing the container, thereby increasing the difficulty of fluid detection.
