Description

Technical Field

[0001] This utility model relates to the field of lubricating oil viscosity measurement technology, and specifically discloses an industrial lubricating oil viscosity measurement device. Background Technology

[0002] The viscosity of a lubricating fluid indicates its ability to detach from a surface; it is defined as the average distance traveled by liquid molecules per unit time. Higher viscosity means greater internal friction and poorer fluidity, but also better lubrication. Conversely, lower viscosity means less internal friction and better fluidity, but also reduced lubrication. Therefore, it is necessary to test the viscosity of lubricating oils.

[0003] Chinese patent CN218157410U discloses a viscosity measuring device for lubricating oil. However, the above patent has certain shortcomings in its use. It cannot control the temperature of the lubricating oil during measurement, and it is not convenient for multiple groups to be measured simultaneously, which reduces the measurement effect of industrial lubricating oil viscosity. Therefore, we propose an industrial lubricating oil viscosity measuring device to solve the above problems. Utility Model Content
