Coated rubber belts (such as conveyor belts, transmission belts, or industrial sealing belts) are widely used in logistics, manufacturing, and mechanical transmission. Proper maintenance and storage can extend their service life and ensure operational efficiency. Detailed maintenance and storage methods are provided below.
Daily Maintenance Key Points
Regular Cleaning
Remove Surface Dirt:
After shutting down, use a soft brush or damp cloth to clean dust, oil, or chemical residue from the rubber belt surface.
Stubborn stains can be removed with a neutral detergent and warm water to avoid corrosion from strong acids or bases.
Check the Coating Condition:
If any peeling, cracking, or hardening of the coating is observed, repair or replace it promptly to prevent further damage.
Precautions During Operation
Avoid Overloading:
Conveyor belts must operate within their rated load. Overloading can cause the rubber layer to tear or joints to separate.
Preventing Tracking:
Adjust the pulleys and idlers to ensure the rubber belt runs centered and minimize edge wear. Controlling Operating Speed:
High-speed operation can easily generate frictional heat, accelerating rubber aging (recommended ≤ 2 m/s).
Lubrication and Anti-Stick Treatment
Non-Working Surface Lubrication:
Apply a small amount of silicone grease to the non-coated side (e.g., the back of the conveyor belt) to reduce friction with the roller.
Anti-Stick Measures:
After conveying sticky materials (such as sugar and resin), promptly clean any residue and spray with an anti-stick agent (such as PTFE spray) if necessary.
Storage Methods
Storage Environment Requirements
Temperature: 10-25°C (Avoid high or low temperatures that can harden or embrittle the rubber).
Humidity: 50%-70% relative humidity to prevent mold and mildew.
Protective Storage: Keep away from direct sunlight and ozone sources (such as motors and transformers).
Proper Storage Methods
Horizontal or Hanging:
For short-term storage, place flat on a pallet. Do not fold.
For long-term storage, hang the conveyor belt (supported by wide brackets to prevent localized deformation).
Dust and Pressure Protection:
Cover with dustproof cloth. Do not stack heavy objects.
Storage Period and Pre-commissioning Inspection
Maximum storage period: Generally no more than one year (chemical rubber belts may be shorter).
Pre-commissioning Inspection:
Check for hardening, adhesion, or deformation.
Perform a manual bend test to confirm there are no cracks before installation.
Safety Instructions
Shutdown Maintenance:
Power must be disconnected and the unit must be locked out (LOTO) before operation.
Protective Tools:
Wear corrosion-resistant gloves and goggles when handling cleaning chemicals.
