As a lifting device, the micro excavator is widely used in many places now, and sometimes the micro mining opportunity will have a failure to speed. In fact, the main reasons for this phenomenon are as follows:
1, engine failure.(speed is too low)
2, air intake system leakage
3. The clearance of the excavator solenoid valve is too large, and the oil supply is insufficient, resulting in the excavator engine losing speed and stalling.
4. Wrong valve clearance.
5. Diesel oil circuit problems
6, one of the engine cylinder operation setting value is wrong.
7, brake and control rod problems and turbocharger carbon accumulation or hydraulic failure.
8, excavator hydraulic system failure.
9, excavator fuel pressure is low, poor fuel quality.
10, the engine load is too large.
11. The brake and turn are not normal.
12, the injection timing is wrong, the fuel amount is not set.
