What are the factors that affect the viscosity of hydraulic oil? Rank index is very important

The viscosity of hydraulic oil is an important index to measure whether a specific oil is suitable for certain types of engines and machines In order to provide optimum performance, the hydraulic oil must be able to withstand pressure and tension when the machine is running There are many factors that can affect the viscosity of the hydraulic oil, such as temperature and the composition of the oil itself Temperature is one of the main factors that can affect the viscosity of hydraulic oil When the machine is running and starts to heat up, the thicker oil starts to thin The goal of selecting the right hydraulic oil is to find out the level and type of protection that can be provided to the engine They will not become too thin to cover the working parts and wear the machine parts due to friction Hydraulic oil is classified into different grades based on the ability to maintain a certain viscosity at a specific temperature Another factor that affects the viscosity of hydraulic oil is the composition of the oil itself This is not only about ingredients and additives, but also about the content of each ingredient There are many types of hydraulic oil, each of which combines different components For example, mineral hydraulic oil uses petroleum base, while synthetic oil may use polyol ester, phosphate ester or water glycol as the core component Some hybrid hydraulic oils also contain additives specifically designed to enhance the product's ability to maintain viscosity in practical applications, even at extreme temperatures For end users, identifying hydraulic oil viscosity involves using an industry standard called viscosity index This index can provide information about various engine oils in specific environment The viscosity grade is also related to the lubricant recommendations provided by the machine manufacturer, so it is easier to identify which hydraulic oil provides the maximum protection for engine parts Using this index can help to prevent the purchase of oil that does not meet the internal temperature of the motor, and ultimately achieve the purpose of reducing wear and continuous operation of the equipment.
