Problems solved by technology

[0004] At present, the lubricating oil used in the engine is mainly replaced regularly by observation, but there are performance differences between different oil products, and the unified oil change cycle has defects, which is not conducive to timely prediction of the state of the engine
Traditional viscosity measurement methods have been developed for a long time, and the technology has been relatively mature, but they are often inconvenient to operate and time-consuming

Description

technical field [0001] The invention relates to a viscosity testing device, in particular to a novel lubricating oil viscosity testing device, which belongs to the field of engineering machinery. Background technique [0002] When the engine is working, the lubricating system continuously transports the lubricating oil to the friction surface of the moving parts and forms a protective oil film to achieve the purpose of lubricating and reducing wear. At the same time, the lubricating oil also has the functions of cooling, cleaning, sealing, and rust prevention. However, with the operation of the engine and the increase in the use time of the lubricating oil, the lubricating oil will gradually age and deteriorate. When the lubricating oil fails, it is easy to aggravate the wear and tear of the engine, and even cause engine failure. Therefore, the quality of lubricating oil is crucial to the reliability and durability of engine operation. [0003] Viscosity, as an important te...
