What are the common problems with XCMG excavators? In-depth analysis of popular topics across the Internet
Recently, among the hot topics in the field of construction machinery, the common faults of XCMG excavators have become the focus of industry discussion. As one of the representative brands of domestic excavators, the performance and stability of XCMG excavators have attracted much attention. This article combines the hot content of the entire network in the past 10 days to provide you with a structured analysis of the common problems of XCMG excavators.
1. Statistics on common fault types of XCMG excavators
| Fault type | frequency of occurrence | Main performance |
|---|---|---|
| Hydraulic system failure | 35% | Insufficient pressure, abnormal oil temperature, slow movement |
| Electrical system failure | 28% | Circuit short circuit, display screen abnormality, sensor failure |
| engine failure | 20% | Insufficient power, black smoke, difficulty starting |
| Walking system failure | 12% | Weakness in walking, deviation, and abnormal noises |
| Other faults | 5% | Cracks in structural parts, oil leakage from oil cylinders, etc. |
2. Analysis of specific fault symptoms
1.Hydraulic system temperature is too high: This is one of the most discussed glitches of late. The main manifestation is that the temperature of the hydraulic oil exceeds 80°C, which leads to accelerated aging of the seals. According to user feedback, this problem occurs more frequently on XE210D and other models.
2.Abnormal pilot pressure: Many users reported that the pilot pressure was unstable during operation, resulting in incoherent movements and affecting operating efficiency. This problem is more common on small excavators such as XE60D.
3.Electrical system false alarm: Recently, there have been many complaints about frequent error messages on the display screen, especially "engine failure" false alarms being the most common. Actual inspection often reveals a sensor or wiring problem.
3. In-depth analysis of fault causes
| Fault phenomenon | Possible reasons | solution |
|---|---|---|
| Hydraulic oil temperature is too high | The radiator is clogged, the hydraulic oil has deteriorated, and the system pressure is too high. | Clean the radiator, replace the hydraulic oil, and check the relief valve |
| Walking astray | Internal leakage of traveling motor, balance valve failure, uneven track tension | Check motor seals, replace balance valve, adjust track |
| Engine powerlessness | Fuel system blockage, turbocharger failure, air filter blockage | Clean the oil circuit, check the supercharger, and replace the air filter |
| slow movements | Insufficient pilot pressure, main pump wear, control valve stuck | Adjust pilot pressure, check main pump, clean control valve |
4. User feedback hot issues
1.XE215C has weak rotation: Recently, many users have reported that this model suffers from insufficient power when turning, especially under heavy load conditions.
2.XE60D makes abnormal noise while walking: Small excavator users have collectively reported on social media that there is a "squeaking" noise when walking. After inspection, it is mostly a problem with the track wheel or guide wheel bearing.
3.XE370CA has high fuel consumption: Some users compared models of the same level and found that the fuel consumption of this model was significantly higher, which may be related to engine tuning.
5. Prevention and maintenance suggestions
1.Regular maintenance: Replace the hydraulic oil and filter element in strict accordance with the requirements of the maintenance manual. It is recommended to replace the hydraulic oil every 2000 hours.
2.daily inspection: Check the hydraulic oil level, coolant level and electrical circuits before each operation, paying special attention to whether there is leakage at the joints.
3.operating instructions: To avoid long-term overload operation, the engine should be warmed up for 3-5 minutes before starting work.
4.winter maintenance: Users in northern areas should use hydraulic oil and diesel suitable for low temperatures to prevent system damage caused by oil solidification.
6. After-sales service satisfaction survey
| Services | Satisfaction | Main questions |
|---|---|---|
| Fault response speed | 78% | Service in remote areas is not timely |
| Maintenance professionalism | 85% | Some technicians lack experience |
| Accessories supply | 72% | Long waiting time for special model accessories |
| service attitude | 88% | Basically meet the needs |
From the above analysis, it can be seen that although XCMG excavators have stable performance, they still have some common problems. Understanding these fault characteristics and taking preventive measures can effectively extend the service life of the equipment. It is recommended that users learn more about the characteristics of each model when purchasing and choose the model that best suits their working conditions.
