In the hydraulic power transmission system of the XCMG XE2000 excavator, the hose assembly is the “flexible artery” that enables precise delivery of high-pressure hydraulic fluid. The hose assembly, part number 803419817, is specifically customized for the core hydraulic circuit of the XE2000 excavator. With its superior pressure resistance and transmission stability, it provides reliable power transmission for the equipment during heavy-duty operations, ensuring rapid response and strong power from hydraulic actuators.
This hose assembly features a multi-layer composite reinforced structure. The inner tube is made of special synthetic rubber that is resistant to high pressure and oil, and undergoes a special vulcanization process, giving it excellent anti-permeability and wear resistance. It can withstand the continuous scouring and chemical corrosion of high-pressure hydraulic oil for a long time, preventing oil seepage or tube wall damage caused by inner tube aging, reducing the risk of hydraulic oil leakage from the source, and ensuring stable system pressure. The intermediate reinforcing layer is made of high-tensile steel wire braided with an optimized braiding density. It can withstand working pressures more than 1.5 times the system’s rated pressure, stably bearing the pressure pulses and impact loads during XE2000 excavator operation, effectively preventing serious malfunctions such as hose bulging and bursting.
In terms of transmission efficiency, the inner diameter of the 803419817 hose assembly is precisely calibrated, and the inner wall smoothness reaches a mirror-like standard, reducing hydraulic oil flow resistance by more than 15% compared to ordinary hoses. This reduces pressure loss and energy loss during oil transmission, ensuring sufficient high-pressure oil is quickly delivered to hydraulic cylinders, hydraulic motors, and other actuators, guaranteeing that key performance parameters such as excavator digging force and swing speed are at their optimal levels. The hose’s minimum bending radius is optimized, allowing for flexible adaptation to installation space in complex piping layouts, avoiding flow attenuation caused by excessive bending, and ensuring continuous and smooth power transmission. In terms of connection reliability, the hose assembly’s connectors are precision-machined from forged steel, with a multi-layer electroplating anti-rust treatment, 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 accuracy controlled within ±0.1mm, 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 803419817 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 803419817 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 803419817 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.
