In the bustling mining engineering sites worldwide, the XCMG XE2000 mining excavator, with its outstanding performance of a 12 cubic meter bucket capacity and over 93% mobility, has become core equipment in mines in Indonesia, the Democratic Republic of Congo, Brazil, and other regions. In the power transmission network of this “mining powerhouse,” the connector with part number 803106345 acts as a “precision bridge,” connecting various pipelines and core components. It is a key connector ensuring the efficient transmission of hydraulic oil, coolant, and other media, providing a solid guarantee for the stable operation of the entire machine.
The XCMG XE2000 excavator connector (part number 803106345) is an original factory component specifically developed based on the piping specifications and connection requirements of the XE2000 excavator’s hydraulic and cooling systems. Its interface dimensions, thread precision, and sealing structure have all been precisely calculated and repeatedly verified, ensuring seamless connection with the machine’s hose assemblies, rigid pipe connectors, and other piping components. Whether connecting high-pressure lines between the hydraulic pump and the main valve, or connecting cooling lines between the radiator and the engine, this connector precisely matches the interfaces of each component, ensuring a secure and smooth connection. It avoids installation difficulties or loose connections caused by dimensional deviations, providing a “tailor-made” precision connection solution for the entire machine’s piping system.
This connector is forged from high-strength alloy steel and undergoes precision machining and surface treatment processes, resulting in excellent pressure resistance, wear resistance, and corrosion resistance. Under the working pressure of hundreds of megapascals in the XE2000 excavator’s hydraulic system, it can stably withstand pressure impacts without easily deforming or cracking. Its precise thread machining process ensures a tight connection, reducing the risk of leakage due to thread wear. Meanwhile, the joint surface undergoes chrome plating and other anti-corrosion treatments, effectively resisting the erosion of oil, water vapor, and dust in the mining environment. Even in harsh operating environments, it maintains stable performance, significantly extending its service life and reducing equipment downtime and maintenance costs due to joint damage.
The power transmission efficiency of the XE2000 excavator is closely related to the sealing performance of the pipeline connections, and the joint is the core component ensuring this seal. This joint is equipped with high-quality seals and a precise structural design, effectively preventing leakage of hydraulic oil, coolant, and other media, ensuring no loss of media during transmission. During the excavator’s high-frequency operating cycles, the joint’s sealing performance remains stable and reliable, avoiding power loss, environmental pollution, and component wear caused by media leakage. This provides strong support for the efficient operation of the entire machine’s hydraulic and cooling systems, ensuring the equipment maintains an availability rate of over 93%. For users operating XCMG XE2000 mining excavators, the connector with part number 803106345 is a key spare part ensuring tight connections in the piping system and efficient media transmission. With its original factory precision fit design, superior durability, and excellent sealing performance, it safeguards power transmission in mining operations, helping you achieve higher economic benefits in the fiercely competitive mining industry.
