803172340 connector XCMG XE2000 excavator spare parts

XCMG XE2000 Excavator Connector (Part No. 803172340): Key to Precise Hydraulic Pipeline Connection

In the high-pressure hydraulic system of large mining excavators, connectors are core components for achieving efficient connection of different pipelines and ensuring stable hydraulic oil transmission. XCMG’s connector (part no. 803172340), specially developed for the XE2000 excavator, utilizes high-strength materials and precision manufacturing processes to become a reliable “connection bridge” for the hydraulic system during heavy-duty operations, providing safe and efficient pipeline connection solutions for engineering teams worldwide.

High-Strength Alloy Forging, Ensuring Connection Strength

The XCMG XE2000 connector (part no. 803172340) is integrally forged from high-quality high-strength alloy structural steel. Authoritative testing shows that its tensile strength reaches 720MPa, and its hardness is controlled between HB250-290, representing a 38% increase in strength compared to conventional connectors in the industry. Through XCMG’s proprietary “precision forging + overall tempering” process, the joint’s internal structure is dense and uniform, with the hardness of key stress-bearing parts increased to HRC40-45, making it less prone to deformation or breakage under high-frequency hydraulic impact. Each joint undergoes four rigorous tests: 48MPa high-pressure water pressure test (35 minutes pressure holding without leakage), ultrasonic flaw detection, thread accuracy inspection (meeting ISO 3H/5g standard), and salt spray test (2200 hours without rust). Actual test data shows that the joint maintains a 99.3% connection reliability rate during 3200 hours of continuous heavy-duty operation, extending its service life by 160% compared to ordinary joints.

Precision sealing design, zero leakage guarantee

To meet the sealing requirements of the XE2000 excavator’s high-pressure hydraulic system, the joint adopts a dual sealing structure of “conical metal seal + elastic sealing ring”. The integrated high-pressure resistant hydrogenated nitrile rubber sealing ring has a Shore hardness of 90±3 degrees, capable of withstanding extreme temperature changes from -42℃ to 140℃, and exhibits no aging or extrusion under long-term working pressure of 42MPa. The sealing ring and sealing groove utilize a combination of mechanical fixing and vulcanization bonding, achieving a bonding strength of 3.8MPa, completely resolving the problem of sealing ring detachment in traditional joints.

The joint’s sealing surface undergoes ultra-precision machining, with the conical surface contact accuracy controlled within 0.01mm. Combined with precision thread machining (pitch error ≤0.015mm), it achieves a reliable seal with uniform force distribution. Actual testing shows that the joint has a zero static leakage rate and a dynamic leakage rate below 0.008L/min, improving sealing performance by 65% ​​compared to traditional products.

Adaptable to all working conditions, stable and reliable performance

This connector is specifically designed for the complex operating environments of the XE2000 excavator, maintaining stable performance in extreme environments such as high-altitude mines at 5500 meters, -42℃ extreme cold regions, 48℃ high-temperature deserts, and high-humidity coastal construction sites. Its surface utilizes a composite anti-corrosion process of “zinc-nickel alloy plating + ceramic sealing,” offering 5 times the corrosion resistance of 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 92% reduction in hydraulic pipeline connection leakage failure rate and a 96% reduction in downtime due to connection problems. In continuous vibration crushing operations, the connector thread preload attenuation rate is less than 4%; after operation in dusty quarries, it maintains smooth loading and unloading performance, ensuring reliable operation of the hydraulic system in various harsh environments.

Original Factory Precise Fit, Enhanced System Efficiency

As a core original factory connecting component from XCMG, the 803172340 connector achieves precise 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 undergone fluid dynamics optimization, reducing flow resistance by 20% and increasing hydraulic oil flow efficiency by 12%.

The installation process employs a “quick positioning” design, allowing for installation and removal within 3 minutes with specialized tools, improving installation efficiency by 75% compared to traditional connectors. Data shows that using the original factory connector can reduce energy loss in the XE2000 excavator’s hydraulic system by 10%, improve maintenance efficiency by 65%, and maintain an overall equipment uptime rate of over 96%. Choosing the XCMG XE2000 original connector (part number 803172340) means selecting a connection safety guarantee 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 engineering projects.
