Product Introduction
1. Energy saving and noise reduction: It adopts engine variable power control technology, has two working modes of power and economy, and is more fuel-efficient; three-level vibration reduction for the engine, cab, and seat; the fan has a large diameter and low speed ratio, the hood is covered with sound-absorbing sponge, and the cab is well sealed, and the noise of the whole machine is reduced.2. Powerful power: It adopts Cummins IV stage variable power engine and selects the optimal torque converter circulation circle diameter to achieve the best match between the torque converter and the engine, reduce the start-up acceleration time of the whole vehicle, and increase the torque output at low speed, which is strong and powerful.
3. Load rotation: The hydraulic system pressure is increased, the blade rotation force is greatly improved, the gear ring is high-frequency quenched, the wear resistance and life are improved, and the load rotation operation is realized.
4. Efficient operation: The displacement of the hydraulic pump and hydraulic motor is increased, and the cylinder speed is increased by 20%. The operation efficiency is leading in the industry. The blade arc is optimized, which can quickly and efficiently turn and discharge the soil, and achieve the best load distribution and the smallest material accumulation in the turntable area.
5. Safe and reliable: CAE global optimization of structural parts, reliable and durable, long life; patented slewing bearing drive axle, long service life and higher reliability; overload protection worm gear box, slewing bearing working device, stronger adaptability; front axle casting joint, longer life.
6. Flexible and maneuverable: single cylinder large steering angle front axle with XCMG patented technology, with articulated frame, small turning radius, maneuverable and flexible.
7. Comfortable operation: diamond-shaped cab six-point support shock absorption, optimized operating mechanism, reduced operating force and operating stroke, operating force reduced by 30%, more flexible and comfortable operation, ergonomic operating system, more comfortable operating environment.
8. Convenient maintenance: large door on the hood, convenient maintenance and maintenance of the whole machine.

FAQ
A common fault troubleshooting for engine failure to start
Rotary Drilling Rig Engine Failure to Start (Fuel Pump Fault)
I. Basic Case Information
- Product: Rotary Drilling Rig
- Model: XCMG XR220D
- Working Hours: 3400
II. Fault Phenomenon
The engine fails to start.
III. Fault Analysis
- The starting motor circuit and key switch circuit were inspected and found to be normal.
- The diesel oil circuit from the fuel tank to the engine was checked for blockage, along with the fuel filter element; both were normal.
IV. Troubleshooting Process
- The oil inlet pipe of the fuel pump was removed, and a large oil output was observed. The hard pipe on the engine common rail was removed for inspection, and a small oil output was found.
- The high-pressure fuel pump was disassembled and cleaned, revealing severe internal wear and impurities such as oil sludge.
- The worn eccentric shaft inside the pump was replaced, and internal impurities were cleaned; the engine started normally afterward.
V. Fault Cause (Conclusion)
Severe internal wear of the fuel pump resulted in failure to build up sufficient fuel pressure, which could not meet the fuel supply pressure required for normal engine start.It is recommended that the customer use higher-quality diesel, replace the filter element in a timely manner, and clean the fuel tank regularly.
