Oil Pan

The main functions of the excavator oil sump are to store lubricating oil, dissipate heat, provide lubrication and cooling, facilitate cleaning and filtering, and ensure sealing.

The oil sump is located at the bottom of the engine and is an important component of the engine’s lubrication system. Its main functions include:

1. Storing lubricating oil: The oil sump can store a certain amount of lubricating oil, ensuring that there is sufficient oil supply during engine operation, maintaining the lubrication state of the internal components.

2. Dissipating heat: The lubricating oil in the oil sump helps to dissipate the heat generated by the engine, lowering the engine temperature and preventing overheating, thus protecting the engine from high-temperature damage.

3. Lubrication and cooling: The lubricating oil forms an oil film inside the engine, reducing friction between components and extending their lifespan. At the same time, the lubricating oil can absorb heat generated by the engine, providing a cooling effect.

4. Cleaning and filtering: The lubricating oil circulates within the engine, carrying away impurities and worn metal particles to keep the engine clean. Filters within the lubricating oil can remove these impurities, ensuring the cleanliness of the oil.

5. Sealing: The oil sump prevents lubricating oil from leaking, ensuring that the oil functions properly within the engine and avoiding loss of oil and the entry of external contaminants.

The design and functionality of the excavator oil sump are crucial for maintaining the engine’s good operating condition and are an indispensable part of the normal operation of the excavator.
