Product Introduction
1. The use of Shanghai Diesel II stage turbocharged engine, the selection of the optimal torque converter circulation circle diameter, the best match between the torque converter and the engine, the reduction of the vehicle startup acceleration time, the increase of torque output at low speed, strong and powerful.
2. 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-carrying rotation operation is realized.
3. The blade arc is optimized, which can quickly and efficiently turn and discharge the soil, achieve the best load distribution and the smallest material accumulation in the rotary disk area.
4. The structural parts are globally optimized by CAE, which is reliable, durable and has a long life; the patented technology slewing bearing drive axle is used, which has a long service life and higher reliability; the overload protection worm gear box and slewing bearing working device are more adaptable; the front axle casting joint has a longer life.

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.
