318503808 blind flange assembly XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Blind Flange Assembly (Part No. 318503808): High-Pressure Sealing Barrier, Safeguarding Efficient Operations

In high-intensity operation scenarios such as large-scale mining and heavy engineering construction, the XCMG XE2000 excavator, with its powerful performance, has become a core piece of construction equipment. The blind flange assembly (part no. 318503808), as a high-pressure sealing component of the machine’s fluid system, bears the heavy responsibility of sealing the openings of key parts such as the hydraulic oil tank, hydraulic valve group, and cylinder cavity, providing a solid guarantee against media leakage in the XE2000’s high-pressure fluid system. It is a core sealing accessory that ensures stable equipment operation.

Precise Fit, Meeting System Sealing Requirements

The hydraulic system, transmission system, and other high-pressure components of the XCMG XE2000 excavator have precise structures, requiring extremely high dimensional accuracy and matching degree from the sealing components. The blind flange assembly (part number 318503808) is specifically designed and manufactured to meet the interface parameters and sealing standards of the XE2000 equipment, precisely matching the installation dimensions, bolt hole positions, and sealing pressure requirements of the corresponding openings. Whether sealing the maintenance port of the hydraulic oil tank or the reserved interface of the valve assembly, this blind flange assembly can perfectly fit the equipment opening, achieving seamless connection through precise dimensional control. This ensures no leakage or deformation under high-pressure conditions (maximum pressure up to 35MPa), providing reliable sealing support for the closed-loop circulation of media in various systems.

High-strength material, resistant to harsh working conditions

In mining environments, blind flange assemblies must withstand multiple challenges, including high-pressure media impact, high-frequency vibration, alternating high and low temperatures, and corrosion from dust and oil. The XCMG XE2000 blind flange assembly (part number 318503808) is manufactured from high-strength alloy steel, undergoing precision forging and heat treatment processes. This gives it excellent compressive strength and deformation resistance, with a tensile strength exceeding 500MPa, effectively resisting the impact of high-pressure media. The sealing surface is equipped with high-quality, oil-resistant and aging-resistant gaskets (such as nitrile rubber and metal spiral wound gaskets), maintaining stable sealing performance within a temperature range of -30℃ to 120℃, resisting long-term corrosion from hydraulic oil, lubricating oil, and other media, and extending its service life.

Precision structure ensures reliable sealing performance

The sealing effect of the blind flange assembly directly depends on the precision of its structural design. The XCMG XE2000 blind flange assembly (part number 318503808) features an optimized sealing structure design. The flange face undergoes high-precision grinding, with a flatness error controlled within 0.02mm/m, ensuring a tight fit with the equipment interface sealing surface. Bolt hole tolerances are controlled within ±0.1mm, ensuring uniform force during installation and preventing seal failure due to excessive local stress. The sealing gasket precisely matches the flange sealing groove, achieving uniform compression through bolt pre-tightening force to form a tight sealing ring. This maintains a stable sealing effect even under high-frequency vibration conditions, eliminating the risk of high-pressure media leakage.

Strict quality control ensures long-term stable operation

XCMG maintains strict quality control over core sealing components throughout the entire production process. The blind flange assembly (part number 318503808) undergoes rigorous testing from raw material selection to finished product delivery. Raw materials undergo multiple inspections, including spectral analysis and mechanical performance testing, to ensure that material composition and strength meet standards. During production, key indicators such as flange flatness, roughness, and bolt hole accuracy are 100% inspected using precision testing equipment. Finished components also undergo rigorous tests such as pressure resistance testing (1.5 times the working pressure), sealing testing, and vibration testing to ensure no leakage or loosening under simulated working conditions. This comprehensive quality control system gives the blind flange assembly extremely high reliability, effectively preventing media leakage and system pressure drop caused by seal failure, reducing equipment downtime for maintenance, and lowering overall user operating costs.

Choosing the XCMG XE2000 excavator blind flange assembly (part number 318503808) means choosing reliable sealing protection under high-pressure environments and continuous, efficient equipment operation. As an important component of XCMG’s high-quality parts system, its robust structural design and precise manufacturing process provide a strong high-pressure sealing defense for your XE2000 excavator during high-intensity operations, facilitating efficient project progress.
