- Key functions & working principle
| Working Principle |
1. Fluid Transfer: The tube acts as a rigid conduit, transporting high-pressure hydraulic oil (or compressed air) from a source (e.g., hydraulic pump) to a destination component (e.g., boom cylinder). |
| 2. Pressure Retention: Its seamless steel structure and thick wall resist expansion under high pressure (up to 40 MPa), maintaining leak-free operation. |
| 3. Compatibility with Fittings: The tube’s precision OD allows secure connection to Komatsu flare/compression fittings – the zinc-plated surface ensures a tight seal and prevents galling (metal sticking) during assembly. |
| 4. Environmental Protection: The corrosion-resistant coating shields the tube from job site debris, moisture, and hydraulic fluid contaminants – extending service life and preventing fluid contamination (which damages pumps/valves). |
| Core Functions |
1. High-Pressure Fluid Conduction: Enables reliable transfer of hydraulic oil to power excavator/loader movements (boom lifting, bucket digging) – critical for equipment productivity. |
| 2. Leak Prevention: Seamless design and tight fittings eliminate fluid leaks – reduces oil waste and prevents job site pollution. |
| 3. Structural Integration: Pre-bent shape integrates with Komatsu equipment frames – saves installation time and avoids interference with other components (e.g., wiring harnesses, fuel lines). |
| 4. Contamination Control: Smooth inner surface minimizes fluid turbulence and particle buildup – protects sensitive hydraulic components (e.g., control valves) from wear. |
| 5. Durability: Seamless steel and zinc coating withstand harsh job site conditions – service life ≥8,000 operating hours. |
