Cleaning Requirements for 100-Ton Single-Arm Hydraulic Press Cylinder System

General Requirements for Cleaning the Hydraulic Cylinder System:

1. Achieve and Maintain Satisfactory Initial Cleanliness Levels:

   - Chemically clean and treat the internal surfaces (components, steel pipes, and hoses) of the single-arm hydraulic press system.

   - Conduct hot oil flushing to reach the targeted cleanliness level.

   - Inspect and evaluate whether the cleanliness of the single-arm hydraulic press has reached the specified requirements.

   - Disassemble and clean the circuit in the following steps to prevent contaminants from entering the already cleaned system: Seals, component connections, and flanges of the single-arm hydraulic press. Implement routine maintenance to ensure cleanliness remains within the controlled target range.

2. Maintaining Cleanliness After Liquid Cleaning:

   - Prevent new contaminants from entering the hydraulic cylinder system of the single-arm hydraulic press.

   - Select appropriate system filters. New oil must be filtered before adding it to the tank.

   - New components and/or valve blocks connected to the single-arm hydraulic press system must meet the aforementioned requirements. After component replacement, disassembly, or similar actions, new cleaning and hot oil flushing are required.

3. Key Points for Cleaning:

   - Sequentially connect the cleaning circuit to the 100-ton single-arm hydraulic press, the oil cylinder system.

   - Components susceptible to damage from high flow rates, moisture, particles, or chemical cleaning agents should be short-circuited (not connected to the cleaning circuit) and cleaned separately.
