Power system technology
1.1 Plateau Adaptability Design
The turbocharger adopts variable cross-section technology (VGT), which shows in the altitude gradient test:
Maintain 100% of the rated power at an altitude of 3,000 meters
At an altitude of 4,500 meters, the power attenuation is only 4.7% (the average attenuation of competing products is 18%)
Dual-mode cooling system
High-temperature mode: Electronic fan + hydraulic oil cooler linkage (Cooling efficiency increased by 35%)
Low-temperature mode: Engine compartment insulation layer + coolant rapid heating device (Start-up time is shortened to 8 minutes in -30℃ environment)
1.2 Innovation in Hydraulic Systems
The main pump adopts a swash plate axial piston design. Volumetric efficiency comparison:
The industry average efficiency of the pressure (MPa)PC520LC-11M0 is 2594%86%, 3591%78%
Innovation of Pilot Control System
Response time of pressure compensation valve: 0.02 seconds (0.05 seconds for traditional system)
Compound action coordination test: When the bucket, boom and rotation are operated synchronously, the flow fluctuation is less than 2.5%
