What is the lubrication system
Excavator Lubrication System
An excavator’s lubrication system is crucial for its efficient and long-term operation. Its primary function is to reduce friction between moving parts, preventing wear and tear, and ensuring optimal performance.
The system typically consists of an oil sump, oil pump, oil filter, and a network of oil lines and passages. The oil pump circulates hydraulic oil throughout the excavator, lubricating various components including hydraulic motors, pumps, cylinders, and bearings.
Hydraulic oil serves a dual purpose: it acts as both a lubricant and a hydraulic fluid. It reduces friction, dissipates heat, and transmits power. Regular oil changes and filter replacements are essential to maintain the lubrication system’s effectiveness and protect the excavator from costly repairs.
Proper lubrication is vital for the overall health and longevity of an excavator.
What type of oil does an excavator use?
Hydraulic oil for excavators consists of mineral oil and other additives, such as organic silicon-based and ethylene glycol-based additives. These additives improve lubrication performance and enhance moisture control.
