Introduction to Seal Adjusters

The seal adjuster is a critical component in the hydraulic system of an excavator. For a model like the PC200-8, it plays a vital role in ensuring the integrity and performance of the hydraulic cylinders, which are essential for executing various excavation tasks efficiently.

Functions of a Seal Adjuster on a PC200-8 Excavator

The primary function of a seal adjuster is to maintain the effectiveness and longevity of seals within hydraulic cylinders. For the PC200-8 excavator, it ensures the hydraulic fluid does not escape during operation, thereby maintaining the necessary pressure for optimal machine performance.

• Prevents fluid leakage: Ensures hydraulic fluid stays within the system.
• Maintains pressure balance: Vital for the operation of hydraulic systems.
• Improves cylinder lifespan: Reduces wear and tear on seals and components.

Components of a Seal Adjuster

The seal adjuster consists of several parts that work together to achieve its function. It typically includes:

• Adjustment Screw: Allows for fine-tuning of the seal tension.
• Lock Nut: Secures the screw in the desired position.
• Wear Ring: Prevents metal-on-metal contact within the cylinder.

Maintenance and Calibration

Routine maintenance and regular calibration of the seal adjuster are imperative for the PC200-8 excavator. Maintenance includes checking for signs of wear and ensuring all components are free of damage.

1. Visual inspection should be conducted every 200 operational hours.
2. Seal replacement is advised every 1,000 operational hours or annually.
3. Calibration involves adjusting the screw to the manufacturer's specified torque settings.
