803401600 XCMG GR2605 motor grader hose assembly

Industrial-grade high-pressure hose assemblies are suitable for hydraulic systems and fluid transport applications, enabling stable media transmission and flexible connections. They are core connection components in engineering machinery and fluid piping systems.

Core Functions and Roles

Media Transmission: Efficiently transmits industrial media such as hydraulic oil, water, and gas, ensuring the continuity and stability of fluid circulation within the system.

Pressure Transmission: Withstands pressure loads during hydraulic system operation, effectively transmitting power and pressure to ensure equipment power output.

Shock Absorption and Buffering: Absorbs vibrations and impacts during equipment operation, reducing pipeline stress concentration and minimizing component wear and resonance.

Flexible Connection: Adapts to the installation requirements of moving parts and articulated joints in equipment, compensating for installation deviations and improving the adaptability of the piping system.

Sealing and Protection: Achieves sealed connections with specialized connectors, preventing media leakage and ensuring the sealing and safety of the piping system.

Suitable Applications

Widely used in hydraulic systems of excavators, loaders, and engineering machinery, as well as hydraulic circuits and fluid transport pipelines in mining machinery, metallurgical equipment, and general industrial equipment, adaptable to various moving and articulated connection parts.

Core Technical Parameters

Material: Inner layer is oil-resistant synthetic rubber, middle layer is high-strength steel wire reinforcement, outer layer is wear-resistant and aging-resistant protective rubber.
Operating Temperature: -40℃ ~ +200℃
Pressure Rating: Suitable for high-pressure hydraulic conditions, meeting the pressure transmission requirements of heavy-duty operations.
Connection Method: Uses quick-connect/threaded connectors, compatible with standard hydraulic connector accessories, easy installation.
Core Features: Pressure and wear resistant, fatigue and aging resistant, good flexibility, reliable connection, long service life.

Troubleshooting and Maintenance

Common Faults: Hose outer layer cracking/damage, connector leakage, hose bulging, pressure leakage, rotation jamming.
Troubleshooting Points: Stop the machine and check the hose’s appearance integrity, connector sealing status, and pipe bending angle; combine this with abnormal operating noises to determine the degree of fault.
Maintenance Points: Regularly check hose wear and aging, tighten connector connections; avoid excessive bending and compression of the pipe; replace damaged parts promptly to ensure normal system operation.
