801143677 pump barrel assembly XCMG XE2000 excavator spare parts

XCMG XE2000 excavator pump cylinder assembly 801143677: the core of hydraulic system power transmission, suitable for heavy-duty mining operations.

In the hydraulic system of the XCMG XE2000 mining excavator, the pump barrel assembly is a key component for the efficient conversion and transmission of hydraulic energy. Pump barrel assembly number 801143677, with its precise structural design and durable performance, serves as a crucial support for ensuring the stable operation of the equipment’s core movements such as digging and slewing. Designed for the high-intensity, high-load operating scenarios in mines, this pump barrel assembly can continuously output stable hydraulic power, helping the equipment cope with complex working conditions.

The 801143677 pump cylinder assembly is strictly matched to the installation specifications of the XCMG XE2000 hydraulic system. The inner wall precision is controlled within Ra0.8μm, and the clearance with the plunger is only 0.005-0.01mm. It can be directly assembled without additional adjustments, significantly reducing downtime for hydraulic system maintenance. It is integrally forged from high-strength alloy steel, and after tempering, its hardness reaches HRC28-32, with a compressive strength exceeding 800MPa. It can withstand the maximum working pressure of 35MPa in the hydraulic system, preventing cylinder wall deformation or cracking due to high pressure and ensuring stable hydraulic power transmission.

The 801143677 pump barrel assembly excels in wear resistance and sealing performance. Its inner wall undergoes multi-layer chrome plating, with a plating thickness of 0.05-0.08mm, improving wear resistance by over 40% compared to ordinary pump barrels and reducing wear caused by the reciprocating motion of the plunger. Simultaneously, the assembly’s built-in specialized sealing groove perfectly fits the sealing ring, effectively preventing hydraulic oil leakage and maintaining stable system pressure. Whether in continuous mining in hard rock or frequent transfer of heavy materials, this pump barrel assembly ensures efficient operation of the hydraulic system, providing strong and stable power support for the XCMG XE2000 and guaranteeing mining operation efficiency.
