XCMG XE2000 Excavator Hoses (Part No. 803419820): High-Pressure Power Transmission, Ensuring Continuous System Power

In the hydraulic power system of the XCMG XE2000 excavator, the hose assembly is the “flexible link” connecting various core components and enabling precise transmission of high-pressure media. The hose assembly, part number 803419820, is specifically customized for the XE2000 excavator’s high-pressure hydraulic circuit. With its superior pressure resistance and transmission stability, it provides reliable power transmission during heavy-duty operations, ensuring efficient operation of the hydraulic system.

This hose assembly features a multi-layer reinforced composite structure design. The inner tube is made of a special high-pressure and oil-resistant rubber material, treated with a special vulcanization process, possessing excellent anti-permeability and wear resistance. It can withstand the continuous scouring and chemical corrosion of high-pressure hydraulic oil for a long time, avoiding oil leakage or tube wall damage caused by inner tube aging, reducing the risk of hydraulic system pressure loss from the source. The intermediate reinforcing layer is made of high-strength steel wire braided with optimized braiding density and wire strength. It can withstand working pressures exceeding 1.5 times the system’s rated pressure, stably bearing the load even under the pressure pulses and instantaneous impacts of the XE2000 excavator. This effectively prevents hose bulging, bursting, and other serious malfunctions, ensuring operational safety.

In terms of transmission efficiency, the inner diameter of the 803419820 hose assembly is precisely calibrated, and its inner wall smoothness meets high industry standards. This results in low hydraulic oil flow resistance, reducing pressure loss and energy dissipation during media transmission. It ensures sufficient high-pressure hydraulic fluid is rapidly delivered to hydraulic cylinders, hydraulic motors, and other actuators, allowing the excavator to respond quickly and powerfully during digging, slewing, and traveling, thus improving operational efficiency. The hose’s bending performance is optimized, allowing for flexible adaptation to installation space in complex piping layouts. The minimum bending radius meets original factory specifications, preventing flow attenuation due to excessive bending and ensuring continuous and smooth power transmission. In terms of connection reliability, the hose assembly’s connectors are precision-machined from high-quality alloy steel, with multi-layer electroplating for rust prevention, providing excellent corrosion resistance and structural strength. The connection between the connector and the hose is secured using a high-pressure crimping process, with crimping precision controlled within strict limits, forming a robust, integrated structure. The joint is tightly sealed, eliminating any risk of loosening or leakage. Even under the intense vibrations generated during excavator operation, it maintains a stable connection, preventing hydraulic oil leakage or air entry into the pipeline due to loose connectors, ensuring the operational stability of the hydraulic system.

Regarding compatibility, the hose assembly with part number 803419820 is an original accessory for the XCMG XE2000 excavator, perfectly matching the interface specifications of key components such as the equipment’s hydraulic pump, main control valve, and cylinders. Parameters such as hose length and connector angle strictly adhere to the original factory design standards, requiring no modification to the pipeline or equipment during installation. It precisely connects to each connection point, ensuring a reasonable pipeline layout and reducing the risk of interference with other components. Whether assembling a new machine or replacing an old part, installation can be completed quickly, significantly reducing equipment downtime for maintenance.

The 803419820 hose assembly excels in durability and environmental adaptability. The outer layer uses weather-resistant rubber material, effectively resisting the effects of UV radiation, ozone corrosion, and alternating high and low temperatures, preventing cracking and hardening over long-term use. It maintains stable flexibility and sealing within a wide temperature range of -40℃ to 120℃, ensuring normal operation in cold winters or high-temperature environments. Simultaneously, the hose surface is equipped with a wear-resistant protective sleeve to reduce damage from friction with other components, further extending its service life. Each hose undergoes rigorous pressure testing, leak detection, and pulse fatigue testing before leaving the factory, ensuring stable and reliable product quality.

When you need to replace the hose assembly for your XCMG XE2000 excavator, choosing the original product with part number 803419820 means choosing efficient power assurance for your hydraulic system. With its superior pressure resistance, high transmission efficiency, and precise adaptability, it safeguards the smooth operation of excavator hydraulic systems, reducing equipment downtime caused by hose failures. This allows you to work with peace of mind in various complex construction scenarios such as mines and infrastructure projects, enabling you to fully accelerate project progress.
