803191635 connector XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Connector (Part No. 803191635): A Reliable Connection Node for High-Pressure Hydraulic Systems

In the high-pressure hydraulic systems of large mining excavators, connectors are key components ensuring stable pipeline connections and efficient hydraulic oil transmission. XCMG’s connector (part no. 803191635), specifically developed for the XE2000 excavator, utilizes high-strength materials and precision sealing technology to become a “core connection point” for stable operation of the hydraulic system during heavy-duty work, providing a safe and durable pipeline connection solution for engineering teams worldwide.

High-Strength Alloy Forging, Forging Superior Connection Strength

The XCMG XE2000 connector (part no. 803191635) is forged from high-quality, high-strength alloy structural steel. Authoritative testing shows that its tensile strength reaches 780MPa, and its hardness is controlled between HB260-300, representing a 45% increase in strength compared to conventional connectors in the industry. Through XCMG’s proprietary “vacuum forging + segmented quenching” process, the joint’s internal structure is dense and defect-free, with the hardness of key stress-bearing parts increased to HRC43-48, making it less prone to deformation or breakage under high-frequency hydraulic impact and heavy-load vibration.

Each joint undergoes five rigorous tests: 52MPa ultra-high pressure water pressure test (40 minutes pressure holding without leakage), ultrasonic flaw detection, thread accuracy inspection (compliant with ISO 3H/4g standards), dynamic fatigue test (250,000 pressure cycles without cracks), and salt spray test (2500 hours without rust). Actual test data shows that the joint maintains a 99.6% connection reliability rate during 3500 hours of continuous heavy-load operation, and its service life is extended by 180% compared to ordinary joints.

Innovative sealing structure achieves zero-leakage operation

Addressing the sealing requirements of the XE2000 excavator’s ultra-high pressure hydraulic system, the joint adopts a triple sealing structure of “metal hard seal + elastic buffer seal + thread sealant”. The integrated high-pressure resistant fluororubber sealing ring, with a Shore hardness of 93±2, can withstand extreme temperature changes from -45℃ to 150℃ and shows no aging or extrusion under long-term working pressure of 48MPa. The sealing ring and sealing groove are mechanically fixed using a dovetail groove + high-temperature vulcanization bonding process, achieving a bonding strength of 4.2MPa, completely solving the industry problem of sealing ring detachment in traditional joints.

The joint’s sealing surface is machined with ultra-precision grinding, achieving a flatness error ≤0.005mm/m and a roughness of Ra0.4μm. Combined with the precise machining of the trapezoidal thread (cumulative pitch error ≤0.01mm), it achieves a rigid seal with uniform force distribution throughout the entire surface. Actual testing shows that the joint has a static leakage rate of zero and a dynamic leakage rate of less than 0.005L/min, improving sealing performance by 75% compared to traditional products.

Adaptable to extreme environments, consistently stable performance

This connector is specifically designed for the multi-scenario operational needs of the XE2000 excavator, maintaining stable performance in extreme environments such as high-altitude mines at 6000 meters, -45℃ extreme cold regions, 50℃ high-temperature deserts, and high-humidity coastal construction sites. Its surface utilizes a composite anti-corrosion process of “nano-ceramic coating + PTFE sealing,” offering 6 times better corrosion resistance than ordinary chrome-plated connectors. It maintains structural integrity and operational flexibility even in acid, alkali, and salt spray environments.

Actual engineering application data shows that XE2000 excavators equipped with this connector experience a 96% reduction in hydraulic pipeline connection leakage failures and a 98% reduction in downtime due to connection problems. During continuous vibration crushing operations, the connector thread preload attenuation rate is less than 3%. Even after operations in quarries with excessive dust concentrations, it maintains smooth loading and unloading performance, ensuring reliable operation of the hydraulic system in various harsh environments.

Original Factory Deep Compatibility, Enhanced System Efficiency

As a core original factory connection component from XCMG, the 803191635 connector achieves micron-level precision matching with the hydraulic pipeline dimensions and pressure parameters of the XE2000 excavator, perfectly aligning with the flow requirements and layout design of the entire machine’s hydraulic system. The connector’s internal flow channels have been optimized through fluid dynamics simulation, reducing flow resistance by 25% and increasing hydraulic oil flow efficiency by 15%.

The installation process employs a “blind-plug quick-lock” design, combined with a guiding positioning structure and specialized tools, enabling installation and removal operations to be completed within 2 minutes, improving installation efficiency by 90% compared to traditional connectors. Data shows that using the original factory connector can reduce energy loss in the XE2000 excavator’s hydraulic system by 13%, improve maintenance efficiency by 75%, and maintain an overall equipment uptime rate of over 97%. Choosing the XCMG XE2000 connector (part number 803191635) means selecting a connection safety barrier for your heavy equipment that has been proven under extreme working conditions. This ensures that the high-pressure hydraulic system maintains zero leakage and high-efficiency operation during high-intensity work, creating greater economic benefits and equipment reliability for your project.
