- Key functions & working principle
| Working Principle |
1. Hydraulic oil is pressurized by the machine’s hydraulic pump (up to 35 MPa) during equipment operation. |
| 2. The 421-03-32170 hose acts as a conduit, transporting the high-pressure oil from the pump to actuators (cylinders, motors) or control valves. |
| 3. The 4-wire spiral reinforcement counteracts internal pressure, preventing the hose from expanding or failing. |
| 4. The outer cover protects the reinforcement and inner tube from external damage, while the NBR inner tube ensures compatibility with hydraulic oil. |
| 5. The hose flexes to accommodate movement of hydraulic components (e.g., excavator boom lifting) without restricting oil flow. |
| Core Functions |
1. High-Pressure Oil Conduction: Delivers pressurized hydraulic oil to power critical equipment functions (digging, lifting, steering), enabling heavy-load operation. |
| 2. Leak Prevention: Factory-crimped fittings and durable inner tube prevent hydraulic oil leakage – oil loss reduces system pressure, impairs performance, and creates safety hazards (slippery surfaces). |
| 3. Component Protection: Shields internal hydraulic components (pumps, valves) from contamination by blocking debris entry through damaged hoses. |
| 4. Environmental Adaptability: Withstands extreme temperatures, ozone, and weather – reliable in hot deserts, cold winters, and humid job sites. |
