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.
