I. No-Load Trial Run Test
Startup Observation: Start the conveyor belt under no-load and observe whether it runs smoothly and whether there are any abnormal vibrations or noises.
Belt Misalignment Check: Focus on whether the conveyor belt edge rubs against the frame and whether the running trajectory is centered.
Tension Recheck: After running for a period of time, check the sag again (it is recommended to be within 1%-2% of the idler spacing).
II. Loading Test
Gradual Loading: Start from a low load and gradually increase to 70%-100% of the rated load.
Operational Observation:
Speed Stability: Whether the speed is uniform under load and whether there is a significant drop.
Motor Current: Whether the current is stable and whether there are any abnormal spikes (which may indicate slippage or overload).
Noise and Vibration: Whether there is any abnormal noise or frame vibration.
III. Key Function Tests
Braking/Stop Test: Test whether the emergency stop function is sensitive and reliable.
Tensioning Device Test: Check whether the tensioning device can effectively compensate for the conveyor belt elongation.
IV. Final Inspection
Comprehensive Inspection: After stopping the machine, check all connecting bolts, idlers, and rollers for looseness.
Data Recording: Record key parameters during the test (such as current, speed, and noise level).
