380906551 XCMG GR2605 motor grader liquid hose

380906551 XCMG GR2605 motor grader liquid hose

3809006551 is a dedicated liquid transfer hose for the XCMG GR2605 grader, suitable for transporting coolant, hydraulic oil, water, and other liquid media. It features resistance to high and low temperatures, oil and pressure, aging, and vibration, ensuring stable operation of the liquid circulation system and preventing leaks and bursts.

Core Functions and Roles

Liquid Media Transport: As a core connecting component of the vehicle’s cooling, hydraulic, and lubrication systems, it enables the directional transport of coolant, hydraulic oil, antifreeze, and other liquids, ensuring the normal operation of the engine, hydraulic components, and cooling modules.

Shock Absorption and Buffering: The flexible rubber material absorbs vibrations during equipment operation, reducing stress on pipes and rigid connections, preventing loose joints and pipe cracking, and is suitable for high-intensity vibration conditions in construction machinery.

Sealing and Protection: The multi-layer composite structure combined with a high-quality sealing layer effectively prevents liquid leakage while blocking external dust, oil, and moisture intrusion, protecting the pipes and surrounding electrical and mechanical components.

Thermal expansion and contraction compensation: Resistant to temperature changes during liquid transportation, possessing a certain degree of flexibility to compensate for pipeline length deformation caused by temperature variations, preventing pipeline twisting and bursting.

Replacement and Maintenance Points

Stop the machine and allow it to cool down before operation to release system pressure and avoid scalding from high-temperature liquid spray or high-pressure liquid leakage;
When disassembling the old hose, clean the joint area of ​​oil and impurities, and check the joint threads and clamps for damage;
When installing the new hose, ensure that the pipeline route is reasonable and free from twisting or excessive stretching. Bend the hose, ensure the joints are securely tightened, and lock the clamps firmly. Avoid contact between the hose and high-temperature components, sharp edges, or moving parts to prevent wear and burns. Conduct regular inspections: In dusty or oily conditions, shorten the inspection cycle, focusing on checking for hose aging, wear, and leaks, and promptly replace worn parts.
