1. Pressure Fluctuations: The Leading Cause of Hose Failure
Most high-pressure hose bursts happen due to pressure issues. When heavy machinery operates, hydraulic lines experience sudden pressure spikes or drops. These changes cause oil pressure to rebound, damaging seals and loosening fittings. Over time, this stress weakens the hose and its connections, making failure more likely.
Preventive action: Operate controls smoothly and avoid sudden movements. Maintain consistent pressure to reduce harmful pressure waves in the system.
2. Improper Hose Connections
When replacing a high-pressure hydraulic hose, ensure the length, number of fittings, and overall configuration match the system’s requirements. Minimize bends and tighten all connections securely. Avoid bending hoses near the fittings, as this creates stress points and increases the risk of failure.
Additional protection: Use protective sleeves on hoses that might rub against other components. This prevents abrasion damage that could lead to bursts.
3. Excessive Oil Temperature
Hydraulic systems generate heat during operation, which raises oil temperature. Elevated temperatures accelerate rubber aging in hydraulic hoses. As elasticity decreases, both strength and sealing performance suffer, increasing the risk of hose failure.
Monitoring tip: If you notice rapid temperature increases, identify and address the cause immediately. Consider installing a temperature gauge for early detection.
Important Safety Notes
Avoid excessive bending – When moving or storing hoses, maintain proper bend radii to prevent internal damage.
Limit ground contact – Keep hoses off the ground when not in use to prevent friction damage and contamination.
Monitor pressure in real-time – Use pressure gauges to ensure system performance stays within safe parameters.
Keep away from heat sources – Position hoses away from hot components. When proximity is unavoidable, use heat-resistant hose sleeves for protection.
