Dongfeng Xinjiang truck parts Air storage cylinder assembly 3513910-T8M300Y

Built to maintain consistent air pressure for Dongfeng Xinjiang’s pneumatic systems, this assembly features a 50L high-capacity cylinder that stores sufficient compressed air to power critical functions (e.g., air brakes, clutch assist, air suspension). It maintains a stable working pressure of 0.8MPa even during peak demand (e.g., frequent brake applications in urban traffic), preventing pressure drops that could compromise braking efficiency. The cylinder’s internal smooth surface reduces air turbulence, minimizing pressure loss during air intake and discharge. Additionally, the integrated pressure relief valve automatically releases excess pressure (above 1.1MPa) to protect the system from overloading. This reliable air storage ensures the truck’s pneumatic components operate smoothly, critical for safe driving and load handling

Constructed from high-strength seamless steel (Q345 grade) with a wall thickness of 4mm, the cylinder withstands a maximum test pressure of 1.5MPa—exceeding the working pressure requirement to ensure safety. The steel surface undergoes hot-dip galvanization + epoxy coating (total thickness: 120μm), which provides double protection against corrosion from road salt, rain, and humidity. It passes 1000-hour salt spray testing (ASTM B117) without rusting, suitable for long-term use in harsh environments (e.g., winter roads, coastal areas). The end caps are welded using automatic submerged arc welding, ensuring airtightness with a leak rate of ≤0.5kPa/h (tested at 1.0MPa). These materials guarantee the cylinder’s service life of over 8 years, reducing replacement frequency

The assembly incorporates comprehensive safety features to protect the Dongfeng Xinjiang’s pneumatic system and the truck itself. A built-in pressure relief valve (set at 1.1MPa) prevents overpressure damage to the cylinder and connected components, automatically releasing excess air if the pressure regulator fails. A drain valve at the bottom allows easy removal of condensed water (a common cause of corrosion and valve blockage), which can be opened manually or connected to an automatic drain system. The mounting brackets are made of high-strength steel with anti-vibration rubber pads, reducing cylinder movement during driving and preventing damage to the air ports or pipeline. Additionally, the cylinder is marked with clear safety labels (working pressure, test date, capacity) in compliance with ISO 11439 standards, ensuring proper use and maintenance

Designed for user-friendly installation, the assembly includes pre-welded mounting brackets that align with the truck’s frame holes. The package comes with 4 M12×40 high-tension bolts, lock washers, and nuts for secure fixation—no specialized tools are needed, and two people can complete installation in 30 minutes. The air ports are equipped with standard NPT threads, allowing direct connection to the factory pneumatic hoses using Teflon tape for sealing (included in the package). Maintenance is simple: the drain valve can be opened monthly to remove condensed water, and the pressure relief valve can be checked annually for proper operation. For repair shops or truck operators, this easy installation and maintenance design minimizes downtime, ensuring the Dongfeng Xinjiang truck returns to service quickly
