Komatsu Excavator Parts Liquid Storage Tank 20Y-979-3120

Liquid storage tanks in excavators are integral components for storing various fluids required for the machine's operation and maintenance. Here's an overview:

Function of Liquid Storage Tanks

1. Hydraulic Fluid: Store hydraulic fluid necessary for powering the excavator's hydraulic system, including cylinders, pumps, and motors.
2. Coolant: Store coolant or antifreeze to regulate the temperature of the engine, preventing overheating and ensuring optimal performance.
3. Fuel: Some excavators have fuel storage tanks to store diesel or gasoline for powering the engine.
4. DEF (Diesel Exhaust Fluid): Store DEF, which is used in selective catalytic reduction (SCR) systems to reduce emissions of nitrogen oxides from the engine exhaust.

Types of Liquid Storage Tanks

1. Hydraulic Reservoir: Specifically designed to store hydraulic fluid for the hydraulic system.
2. Coolant Reservoir: Stores coolant or antifreeze for engine cooling systems.
3. Fuel Tank: Stores diesel or gasoline for engine fuel.
4. DEF Tank: Stores DEF for emission control systems in modern diesel engines.

Components of Liquid Storage Tanks

1. Tank Body: The main container that holds the liquid, typically made of metal, plastic, or composite materials.
2. Filler Neck/Cap: Provides access for filling the tank with fluid and may include a cap to prevent contamination.
3. Level Indicator: Allows operators to monitor the fluid level inside the tank to ensure adequate supply.
4. Drain Valve: Allows for easy drainage and maintenance of the tank contents when needed.
5. Mounting Brackets: Securely attach the tank to the excavator's frame or chassis.
