XCMG XE2000 Excavator Piston Ring (Part No. 800169011): The Core Sealing and Wear-Resistant Component in the Engine Cylinder

The XCMG XE2000 mining excavator, with its 192,000kg operating weight, 810kW imported engine, and 10-14m³ large bucket capacity, continuously delivers powerful performance in heavy-duty mining operations worldwide. The piston ring (part no. 800169011), as a key sealing component within the engine cylinder, is a core component ensuring the airtightness of the combustion chamber and controlling oil consumption, directly affecting the engine’s power output, fuel economy, and service life.

This piston ring is manufactured using a high-strength alloy cast iron and chrome-plated composite process, possessing excellent wear resistance and elastic recovery capabilities. The first piston ring features a porous chrome-plated surface with a hardness exceeding 950HV, effectively resisting the scouring and friction of high-temperature, high-pressure combustion gases within the cylinder. The oil ring employs a combined structural design, with specially reinforced oil-scraping blades that maintain stable oil scraping performance during high-speed piston reciprocating motion, preventing oil from entering the combustion chamber and causing carbon deposits, thus providing a durable and reliable guarantee for cylinder sealing.

In terms of design, it was specifically developed based on the cylinder bore, stroke parameters, and combustion conditions of the XE2000 engine. The ring diameter, opening clearance, and side clearance underwent multiple rounds of optimization and calibration. The piston ring uses a barrel or conical surface design, forming a line contact seal with the cylinder liner inner wall, quickly establishing an effective seal under both hot and cold engine conditions, with compression pressure loss controlled within 3%. The radial elasticity of the oil ring is precisely matched, ensuring effective oil scraping while reducing cylinder liner wear, extending cylinder liner life by more than 30%.

Relying on XCMG’s advanced manufacturing processes, this piston ring undergoes rigorous precision machining and performance testing. High-precision machining is performed using CNC lathes, with ring diameter tolerance controlled within 0.005mm and opening clearance error not exceeding 0.01mm. The surface undergoes precision grinding and polishing, with a roughness controlled within 0.2μm to ensure a good fit with the cylinder liner. Each set of piston rings undergoes elasticity testing, sealing performance testing, and wear resistance testing to ensure stable performance under high temperature, high pressure, and high load conditions.

The performance of the piston rings directly affects the engine’s operating efficiency and operating costs. During the engine’s working cycle, it prevents gas leakage through reliable sealing, ensuring complete combustion and enabling the XE2000 excavator to output stronger power during heavy-duty operations. Its efficient oil scraping function controls oil consumption to below 0.5g/kW·h, reducing oil loss and emissions. Excellent wear resistance reduces abnormal wear on the cylinder liner and piston, extending engine overhaul intervals and reducing equipment maintenance costs. Choosing XCMG XE2000 excavator piston rings (part number 800169011) not only provides you with a high-quality core component that is reliable in sealing and durable, but also allows you to enjoy timely parts supply and professional technical support through XCMG’s global service network. Let this wear-resistant, sealed core component inside the engine cylinder provide a solid foundation for the power output of your mining equipment’s engine, ensuring continuous and efficient production.
