I. Classification of Hydraulic Oils
There are many types of hydraulic oil, mainly divided into three categories: mineral oil type, emulsion type, and synthetic type. According to national standards, lubricants and related products belong to category L, with group H being hydraulic fluids for hydraulic systems (excluding automotive brake fluids and aviation hydraulic fluids for the time being). Further classification is then based on the composition and characteristics of the products, such as a specific product being named L-HM32 (where 32 represents the viscosity grade of the fluid). The hydraulic transmission system of fire trucks commonly uses mineral oil type hydraulic oil.
Mineral oil-based hydraulic oils offer good lubricity and rust prevention, with a wide viscosity grade range, making them widely applicable in hydraulic systems. Statistics show that over 90% of hydraulic systems currently use mineral oil-based hydraulic oils as their working medium.
Section II: Selection of Hydraulic Oil Varieties
When selecting the type of oil, prioritize the hydraulic oil recommended by the product, as this is crucial for ensuring the reliability and lifespan of the equipment. If a specific hydraulic oil is not available, consider factors such as working pressure and temperature range. For garbage truck hydraulic systems, it is recommended to first choose L-HM or L-HV oil. For low-pressure hydraulic systems without valuable hydraulic components (such as standard dump trucks) where the aforementioned hydraulic oils cannot be obtained, L-HL general hydraulic oil can be used, and L-HH oil (for total loss systems) should be avoided as much as possible.
