SHANTUI SD22/SD32 Bulldozer NT855 Oil Pump 3042378
The oil pump in a bulldozer is a core component of the engine lubrication system. Its function is to draw oil from the oil pan, pressurize it, and force it to the friction surfaces of all moving parts of the engine to ensure proper lubrication, cooling, cleaning, and sealing.
Main Functions
Lubrication: Reduces friction between parts, prevents wear, and extends engine life.
Cooling: Circulating oil removes heat generated by the engine, preventing overheating.
Cleaning: Oil circulation removes metal shavings and other impurities, keeping the engine interior clean.
Sealing: Forms an oil film on pistons, valves, etc., to help seal combustion gases and fuel.
Working Principle
Oil pumps are mostly gear pumps, composed of a driving gear and a driven gear. When the engine is running, the camshaft drives the drive gear to rotate. The gear throws the oil from the oil inlet to the oil outlet, creating a low-pressure oil intake. The oil pressure at the oil outlet increases and is forced into various lubrication points to achieve forced lubrication.
