In the piping system of the XCMG XE2000 large excavator, the connector (part number: 803174799) is a key component for achieving efficient connection and reliable sealing of different pipelines. Like a “precision node” in the pipeline network, it plays a crucial role in the stable delivery of media in hydraulic, fuel, and cooling systems, providing a solid connection guarantee for the overall performance of the XE2000 during high-intensity operations.
Connector 803174799 is an original factory part custom-designed by XCMG for the XE2000 excavator. Its design fully utilizes the 3D model data of the machine’s piping system, achieving a high degree of matching with the equipment interface. Through high-precision machining equipment, strict control over key parameters such as thread specifications, interface dimensions, and sealing surface flatness ensures a “zero-gap” connection between the connector and the corresponding pipeline. Whether it’s system setup during new machine assembly or component replacement during later maintenance, no additional adjustments to pipeline positions or grinding of interfaces are required, enabling direct and rapid installation. This precise adaptability not only reduces installation difficulty but also avoids connection loosening issues caused by dimensional deviations, ensuring the initial sealing performance of the pipeline system from the source.
During operation, the media within the pipeline system of the XE2000 excavator is often under high pressure, placing extremely high demands on the sealing performance of the connections. Connector 803174799 employs a multi-seal structure design, equipped with high-quality seals at the interface, forming a highly efficient sealing interface through precise dimensional matching. Simultaneously, the thread machining precision of the connector meets high industry standards, generating uniform preload during tightening to ensure the seals fully conform to the sealing surface, effectively preventing media leakage. Even under conditions of severe equipment vibration or pressure fluctuations, it maintains a stable sealing effect, preventing system pressure drops, component wear, and other malfunctions caused by media loss, ensuring the efficient operation of the pipeline system.
XCMG maintains strict quality control over the 803174799 connector throughout the entire production process, committed to creating a durable core component. The connector is forged from high-strength alloy material and strengthened through a tempering heat treatment process, possessing excellent compressive strength and fatigue resistance, capable of withstanding high-pressure impacts and equipment vibrations in pipeline systems for extended periods. The surface undergoes multi-layer anti-rust and anti-corrosion treatment, forming a dense protective coating that effectively resists corrosion from moisture, oil, dust, and other pollutants in the working environment, extending its service life. Each connector undergoes multiple rigorous inspections before leaving the factory, including pressure testing, sealing tests, and dimensional accuracy verification, ensuring no cracks, sand holes, or other quality defects, providing users with a stable and reliable pipeline connection solution.
Choosing the XCMG XE2000 excavator connector 803174799 means choosing a reliable “connection barrier” for your equipment’s pipeline system. With its precise factory compatibility, superior sealing performance, and durable quality, the XE2000 excavator ensures continuous and stable media delivery, enabling efficient operation in complex conditions such as mining and infrastructure projects, and safeguarding project progress.
