Debugging of Cylinder Initial Cleaning Screen

The debugging of the cylinder initial cleaning screen is crucial for ensuring efficient operation and precise screening.

No-Load Trial Run

Equipment Startup

After powering on, start the cylinder initial cleaning screen and observe if the startup is smooth. Ensure the motor runs normally without unusual noises or stalling. Check the control panel to confirm that all indicator lights and data displays are normal.

Check Operating Condition

Let the equipment run unloaded for 10 - 15 minutes and closely observe the rotation of the cylinder. Ensure the cylinder runs steadily without significant vibration or wobbling. Check all connection points to ensure bolts and nuts are tight and not loose. Also, inspect seals for any grain or air leakage.

Confirm Motor Rotation Direction

By observing the rotation direction of the cylinder, confirm if the motor rotation is correct. If the cylinder rotates in the opposite direction to the equipment's marking, promptly adjust the motor's phase sequence. Typically, swapping any two power lines can correct the motor rotation.

Load Commissioning

Feed and Discharge Inspection

Slowly feed a small amount of grain into the equipment and observe the feed inlet. Ensure grain enters the cylinder evenly and smoothly without blockages or accumulation. Also, check the discharge and impurity outlets to ensure screened grain and impurities are smoothly discharged.

Screening Effect Assessment

Adjust the screen hole size and cylinder speed based on the screening results. If the screening is poor, such as excessive impurities or grain loss, promptly adjust the screen hole size. Also, adjust the cylinder speed according to the grain type and characteristics to achieve the best screening effect.

Equipment Operating Stability

During loaded operation, continuously monitor the equipment's condition. Check if the motor current and voltage are stable, ensuring the equipment runs at rated power. Also, monitor the cylinder speed and vibration to ensure smooth operation without unusual noises or vibrations.

Parameter Optimization

Adjust Feed Rate

Adjust the feed device speed based on the equipment's capacity and grain flow. Ensure grain enters the cylinder evenly and continuously to avoid overloading the equipment or poor screening due to too fast a feed rate.

Fine-Tune Cylinder Speed

Fine-tune the cylinder speed by adjusting the motor speed controller. Different grain types and screening requirements need different speed settings. Generally, smaller-grained grain requires a lower speed, while larger-grained grain needs a higher speed.
