21 Ton XCMG XE215D Crawler Excavator Reliable And Durable
XCMG XE215D excavator engine is powerful, durable and low fuel
consumption, which can meet all application requirements. Combining
time-tested, sturdy and durable components and sophisticated
manufacturing processes, it has higher reliability and efficiency.
2. more efficient returns
1. Low-speed, high-torque, fully electronically controlled engine
that meets the working conditions of the excavator, and the torque
reserve is increased by 15%. The fully electronically controlled
high-pressure common rail engine technology, fuel efficiency is
increased by 5%;
2. High-efficiency and large-displacement motor, rotary motor
increases displacement and increases the rotary torque of the whole
machine by 12.1%
3. The industry's first large-displacement and high-efficiency
pump, the displacement increased by 13.6%, the power increased by
4.5%, and the whole vehicle moved faster.
4. Innovate the power matching mode, optimize the power matching
between the pump and the engine, replace the new generation of
electrical systems, add engine speed sensing control in the ESS
mode, make full use of the engine power, and increase the product's
operating efficiency by 10%.
3. more reliable and durable
1. High-quality integrated electrical system, higher index,
centralized electrical control, simpler design and more reliable
system.
2. High-reliability working device. Through computer optimization
design and three-dimensional solid modeling design, the box
structure of the working device is optimized to form XCMG's own
patented technology.
3. The thermal management system has been developed to improve the working temperature environment of the engine and hydraulic system, improve the system efficiency, reduce fuel consumption, and extend the life of components.
