380906556 XCMG GR2605 motor grader liquid hose

380906556 XCMG GR2605 motor grader liquid hose

380906556 is the original liquid transfer hose for the XCMG GR2605 motor grader. It is suitable for transferring media such as hydraulic oil and coolant, and features high temperature resistance, aging resistance, and reliable sealing to ensure stable operation of the hydraulic and cooling piping systems.

Core Functions and Roles

Media Transfer: Used for the directional transfer of liquids in the hydraulic and cooling systems of motor graders, transmitting core working media such as coolant and hydraulic oil to maintain the normal operation of the equipment’s power and heat dissipation systems.

Shock Absorption and Buffering: The flexible structure absorbs vibrations during equipment operation, reduces pipeline stress, prevents joint loosening and pipeline cracking, and is suitable for high-intensity operating conditions of construction machinery.

Sealing and Protection: The multi-layer structure combined with a sealing layer effectively prevents liquid leakage, blocks dust and oil intrusion, and protects pipelines and surrounding electrical and mechanical components.

Deformation Compensation: Adapts to thermal expansion and contraction of pipelines and equipment displacement, absorbs installation errors, avoids pipeline twisting and bursting, and extends system service life.

Replacement and Maintenance Points

Disassemble after depressurizing and cooling the system to prevent burns from high-temperature liquids and leaks from high-pressure liquids;
Clean oil and impurities from the joints, and check for damage to flanges and threaded connections;
Avoid twisting and excessive stretching during installation, and tighten the joints to the specified torque to ensure a tight seal;
Avoid contact between the hose and high-temperature components and sharp edges to prevent wear and burning;
Regular Inspection: Shorten the inspection cycle under harsh operating conditions, focusing on checking for aging and leaks, and promptly replacing any faulty parts.
