Dismantled parts from PC200-8M0.
The Hydraulic Oil Tank of the Komatsu PC200-8M0 excavator is a critical component of the hydraulic system, which powers the machine’s operations such as lifting, digging, and rotating. Here's a detailed description:
-
Material: The tank is generally made from steel or other durable metals to handle the pressurized environment and protect the hydraulic oil from external contaminants. It is designed to be robust, resistant to corrosion, and capable of withstanding vibrations from the machine.
-
Capacity: The hydraulic oil tank typically holds a significant volume of hydraulic fluid to ensure smooth operation of all hydraulic functions. For a Komatsu PC200-8M0, the tank capacity is typically around 130-140 liters (or approximately 34-37 gallons), though this can vary slightly depending on model variations.
-
Function:
- Reservoir: The primary function of the hydraulic oil tank is to act as a reservoir for the hydraulic fluid. The fluid is stored and pumped through the hydraulic circuits to operate various components like the boom, arm, and swing motor.
- Cooling: It also plays a role in dissipating heat generated from the hydraulic system as the oil cycles through, preventing the hydraulic system from overheating.
- Filtration: Inside the tank, there is usually a filter or a filtration system that ensures the hydraulic oil is clean and free of debris, maintaining the efficiency and longevity of the hydraulic components.
- Pressure Regulation: The tank helps to regulate the hydraulic fluid pressure, which is essential for the machine's efficient operation.
-
Design:
- Shape and Position: The tank is generally rectangular or cylindrical in shape and is located within the machine's frame, often in the rear section of the excavator for balance and easy access during maintenance.
- Fittings and Ports: It features several fittings and ports for the fluid inlet and outlet, as well as for filling and draining the hydraulic oil. A vent or breather cap is typically included to allow air exchange, preventing pressure buildup inside the tank.
-
Monitoring: The hydraulic oil tank is equipped with a sight gauge or level indicator to monitor the fluid level easily. Additionally, there may be sensors for monitoring the temperature and pressure of the hydraulic oil to ensure the system operates within safe limits.
-
Maintenance: Regular inspection and maintenance are essential to ensure the hydraulic oil tank remains in good condition. This includes checking the oil level, changing the oil filter, and inspecting for leaks or signs of wear.
In summary, the Hydraulic Oil Tank of the Komatsu PC200-8M0 plays a vital role in storing and managing hydraulic fluid, which powers the machine's hydraulic systems, ensuring smooth and efficient operation.
