Key Factors Affecting Lifespan
1. Material and Structure: High-quality PU material combined with a high-tensile-strength polyester canvas skeleton significantly improves wear resistance and tensile strength, extending the service life.
2. Working Environment:
Temperature: PU conveyor belts typically withstand temperatures from -10℃ to +80℃. Prolonged operation in environments exceeding 80℃ will accelerate aging and drastically shorten lifespan.
Humidity and Chemical Contact: Moisture, oil, and disinfectants (such as alcohol) can cause hydrolysis or corrosion, reducing material stability.
3. Load and Operating Conditions: High loads, frequent starts and stops, and improper tension (too tight or too loose) will all exacerbate wear, leading to premature failure.
4. Daily Maintenance: Regular cleaning, checking for misalignment, adjusting tension, and avoiding scratches from sharp objects can effectively extend lifespan. Neglecting maintenance can shorten lifespan by more than 30%.
Vulnerable Parts and Replacement Signals
1. Joints: Gaps exist at these joints, making them susceptible to impact and wear, and are high-risk areas for breakage.
2. Middle section: This area bears the material for extended periods and experiences the most frequent friction, making it prone to thinning or cracking.
3. Skirt contact area: Improper adjustment of the material guide device can cause abnormal localized wear.
4. Replacement timing: When obvious cracks, edge damage, loose joints, continuous deviation, or slippage appear, the part should be replaced immediately to avoid downtime losses.
