Description

Technical Field

[0001] The utility model relates to the technical field of oil viscosity detection, in particular to an oil viscosity detection device. Background Art

[0002] An oil viscosity detection device is a device used to measure the viscosity of lubricating oil. Viscosity is an important index of the flow characteristics of lubricating oil, which affects the flow performance of lubricating oil in equipment. A viscometer is a device commonly used for oil viscosity detection. A viscometer usually uses rotational or extensional technology to measure the viscosity of a liquid. A rotational viscometer determines its viscosity by measuring the rotational resistance of a liquid on a rotating cylinder or cone, while an extensional viscometer measures the viscosity of a liquid by applying a certain force to make the liquid flow.

[0003] After lubricating oil is used for a period of time, it will age and deteriorate, and it will not be able to lubricate the equipment sufficiently, thus increasing the failure rate of the equipment and reducing the service life of the equipment. Therefore, it is necessary to detect the viscosity of lubricating oil regularly or irregularly. When the viscosity of the lubricating oil does not meet the use requirements, the lubricating oil should be replaced in time to improve the service life of the equipment. However, the existing detection of lubricating oil viscosity is relatively complicated. It is necessary to extract the lubricating oil from the lubricating oil tank and send it to the laboratory for inspection. The detection time is long and the process is cumbersome. Therefore, researching a new type of oil viscosity detection device to solve the above problems is of great significance for improving the use convenience of the oil viscosity detection device.
