What is the reason why the excavator is stuck?
Recently, the issue of excavator holding power has caused widespread discussion in the field of construction machinery. Many excavator operators and maintenance masters reported that the excavator often stalls during operation, which seriously affects work efficiency. This article will combine the hot topics and hot content on the Internet in the past 10 days, conduct an in-depth analysis of the reasons why the excavator is stuck, and provide structured data to help readers better understand this issue.
1. The main performance of excavator hold-up
Excavator machine stalling usually manifests itself as a drop in engine speed, lack of power, slow movement or even sudden stalling. The following are some common manifestations:
| Performance | Possible reasons |
|---|---|
| Engine speed drops | Fuel system problems, clogged air filter |
| Lack of motivation | Hydraulic system failure, insufficient engine power |
| slow movements | Hydraulic oil contamination, pump valve wear |
| Sudden flameout | Fuel supply interruption, circuit failure |
2. Common reasons why excavators are stuck
According to the discussions and expert analysis on the entire network in the past 10 days, the reasons for the excavator to hold up the machine are mainly concentrated in the following aspects:
| Cause classification | specific reasons | solution |
|---|---|---|
| fuel system problems | Fuel filter clogged, fuel pump failure | Replace filter and overhaul oil pump |
| air filter clogged | The filter element is too dirty and the air intake is not smooth. | Clean or replace filter element |
| Hydraulic system failure | Hydraulic oil contamination, pump valve wear | Replace hydraulic oil and repair pump valves |
| Insufficient engine power | Turbocharger failure, fuel injector problem | Repair supercharger and clean fuel injector |
| circuit problem | Sensor failure, line aging | Replace sensor and check circuit |
3. How to prevent the excavator from holding up the machine
To prevent the excavator from holding up, you need to start with daily maintenance and standardized operations. The following are some suggestions:
1.Regular maintenance: Replace the fuel filter, air filter and hydraulic oil on time to ensure smooth operation of each system.
2.Check hydraulic system: Regularly check the quality of hydraulic oil and the status of pump valves to avoid machine downtime due to contamination or wear.
3.Standardized operations: Avoid long-term overload operation and reasonably control engine speed and hydraulic pressure.
4.Timely maintenance: When an abnormality is discovered, the machine should be shut down immediately for inspection to prevent small problems from turning into major failures.
4. Analysis of recent popular cases
According to the discussions on the entire network in the past 10 days, the following are several typical cases of excavator holding up:
| Case | Problem description | solution |
|---|---|---|
| Case 1 | The excavator suddenly stalled during operation, and the fuel filter was found to be clogged. | Returned to normal after replacing filter |
| Case 2 | The excavator moves slowly, and the hydraulic oil test found serious contamination | Change hydraulic oil and clean system |
| Case 3 | The excavator lacks power and the turbocharger has serious carbon deposits. | Problem solved after cleaning the supercharger |
5. Summary
Excavator machine stalling is a common but complex problem that may involve multiple aspects such as the fuel system, hydraulic system, engine, and circuits. Through regular maintenance, standardized operation and timely inspection, machine holding problems can be effectively prevented and solved. We hope that the structured data and case analysis in this article can provide valuable reference for excavator operators and maintenance personnel.
