The invention provides a test platform for setting kinematic viscosity at non-room temperature and an operation method thereof. The test platform comprises a temperature-control constant temperature oil tank, a dual-layer setting oil tank and a capillary viscometer positioning regulating device that are separate, wherein the temperature-control constant temperature oil tank is filled with heat conductive oil and is communicated with the dual-layer setting oil tank through a liquid, the interior of an inner tank of the dual-layer setting oil tank is a working area, a mixing area is between theinner tank and an outer tank, both the side wall and the bottom wall of the inner tank are provided with diversion gate holes, the capillary viscometer positioning regulating device comprises an installation positioning support and a position regulation mechanism, the installation positioning support is used for fixing a capillary viscometer, the position regulation mechanism can drive the installation positioning support to move vertically so as to regulate the capillary viscometer, and the vertical degree of the capillary viscometer is regulated through depth of heat conductive oil immersedinto the working area through a capillary viscometer through hole and front and back, left and right deflection. Kinematic viscosity of viscosity transfer standard solution can be set and measured accurately at non-room temperature.
Description
technical field [0001] The invention relates to the calibration and determination of the kinematic viscosity of a viscosity transfer standard solution, which belongs to the field of measurement and calibration, in particular to a test platform for determining the kinematic viscosity at a non-room temperature and an operation method thereof. Background technique [0002] The temperature range of viscosity measurement in my country is relatively narrow, only limited to about room temperature, and the viscosity transfer standard solution is almost blank at non-room temperature. With the development and progress of society, the fields of medicine and health, petrochemical industry, solar heat transfer and heat storage, preface scientific research and other fields in our country put forward the demand for viscosity measurement in the non-room temperature range, so how to complete the accurate determination of the viscosity transfer standard solution in non-room temperature It has...
