Why is the walking motor weak?
As the core component of construction machinery, the traveling motor's performance directly affects the working efficiency of the equipment. Recently, many users have reported that the walking motor has insufficient power. This article will combine the hot topics and hot content on the Internet in the past 10 days, analyze the common causes of weak walking motors, and provide structured data to help you quickly locate the problem.
1. Common causes of weak walking motors
According to recent maintenance cases and industry discussions, the main reasons for the lack of power in the walking motor can be divided into the following categories:
| Cause classification | Specific performance | Proportion |
|---|---|---|
| Hydraulic system problems | Insufficient pressure, oil contamination, pump wear | 42% |
| Damage to mechanical parts | Internal wear of the motor and bearing failure | 28% |
| Control system failure | Sensor failure, circuit problem | 18% |
| Improper operation | Overloaded work and no regular maintenance | 12% |
2. Detailed cause analysis
1.Hydraulic system problems
Hydraulic oil is the power source of the traveling motor. Oil contamination or insufficient pressure will cause the motor power to decrease. Recently, users on multiple forums reported that about 60% of travel motor failures are related to hydraulic oil.
| Hydraulic system problems | Detection method | solution |
|---|---|---|
| oil contamination | Observe oil color and detect impurities | Replace hydraulic oil and filter element |
| Pump wear | Pressure test, flow detection | Repair or replace hydraulic pump |
| system leak | Check pipes and joints | Replace seals or lines |
2.Damage to mechanical parts
Wear of the plunger, valve plate and other components inside the motor will lead to a decrease in efficiency. According to statistics from a maintenance platform, the probability of mechanical wear of walking motors that have been used for more than 5,000 hours is as high as 75%.
3.Control system failure
As the degree of electronics in engineering machinery increases, the problem of walking inability caused by sensor and circuit failures is increasing. The recent recall of a certain brand was caused by a defect in the control module program.
3. Prevention and maintenance suggestions
1. Replace hydraulic oil and filter element regularly (recommended every 2000 hours or according to manufacturer’s requirements)
2. Avoid working overloaded for long periods of time
3. Check system pressure monthly
4. Store spare control modules for quick diagnostics
| maintenance items | cycle | cost estimate |
|---|---|---|
| Hydraulic oil replacement | 2000 hours | 500-2000 yuan |
| Filter element replacement | 500 hours | 200-800 yuan |
| System check | per month | 100-300 yuan |
4. Latest industry trends
Recently, a well-known manufacturer has launched a new wear-resistant motor, claiming that it can extend the service life by 30%. Another study shows that the use of intelligent diagnostic systems can reduce sudden failures by 60%.
From the above analysis, it can be seen that the lack of power in the walking motor is usually a problem caused by multiple factors. It is recommended that users establish a complete maintenance plan and pay attention to the latest technological developments to ensure the best working condition of the equipment.
