Doosan Daewoo intake bellows (model 65083100010) is a core component of the excavator engine intake system, used to connect the air filter with the engine intake manifold, and plays a key role in guiding flow, sealing and vibration isolation. This product is made of high-strength rubber-plastic composite materials, with an embedded metal support structure (such as a steel wire reinforcing layer) inside. The corrugated cross-section is designed as rectangular or arc-shaped, effectively enhancing the rigidity of the pipe body and its resistance to negative pressure, thus avoiding the problem of insufficient air intake caused by negative pressure flattening during high-power engine operation. Its corrugated tube body has excellent elasticity, which can absorb the vibration and assembly errors during equipment operation, reduce resonance noise and extend the service life of adjacent components.
Core features and advantages:
Reinforced structural design: Metal supports (such as steel wire layers) are built into the trough of the corrugated pipe to ensure that the pipe body does not deform under extreme working conditions and to guarantee smooth air intake.
Outstanding material properties: Oil resistance, high-temperature resistance (suitable for environments ranging from -30℃ to 120℃), anti-aging, and compatible with the harsh conditions in the engine compartment.
Wide compatibility: Specifically designed for Doosan Daewoo excavator series (such as DH220-5, DH300LC-7, DH450, etc.), the installation interface is standardized and compatible with the original factory specifications.
Dual versions available: We offer original quality products and also provide alternative versions from third-party manufacturers with similar performance and lower costs, meeting the diverse needs of maintenance budgets.
Application scenarios
It is mainly used for the maintenance and repair of the engine intake system of Doosan Daewoo excavators, and is suitable for equipment maintenance in fields such as mining, construction, and civil engineering, significantly improving the stability of engine power output and fuel efficiency.
Procurement suggestion
Genuine products can be purchased through Ningbo Qiuning Trading Co., LTD.
The third-party alternative version is suitable for non-extreme working conditions and has a high cost performance. However, it is recommended to regularly check the replacement cycle.
When installing, make sure the clamps are securely fastened to prevent leakage and regularly clean the impurities in the pipeline.
Notes
When choosing third-party products, it is necessary to confirm the material of the pipe body and the integrity of the support structure.
It is recommended to conduct routine inspections in combination with the equipment maintenance cycle and replace aged parts in a timely manner.
This product takes reliability and adaptability as its core, providing a guarantee for the continuous and efficient operation of equipment.
