The drum screen in grain silos is a key device for ensuring grain quality and production efficiency. To ensure efficient operation and extend its service life, scientific maintenance measures are essential.
During daily operation of the drum screen in grain silos, closely monitor the equipment's condition. For example, high motor current may indicate an overload, abnormal operating sounds could suggest issues, and excessive drum vibration might involve imbalance or loose parts. Thorough monitoring can promptly detect abnormal signals.
If abnormalities are detected, such as a spike in motor current, unusual noises, or increased drum vibration, immediately shut down the machine for a full inspection. This step aims to prevent minor faults from causing major problems, reducing equipment damage and repair costs. For instance, unusual noises may stem from worn bearings or loose fasteners, and timely checks can prevent fault escalation and ensure the safety of both equipment and grain.
When the drum screen is not in use, the storage environment is crucial. The equipment should be placed in a dry, ventilated area free of corrosive gases, away from dampness, high temperatures, and corrosion risks. For example, outdoor storage exposes the equipment to rain, direct sunlight, and temperature fluctuations, accelerating component aging and damage. An ideal storage environment can significantly reduce the impact of natural factors on the equipment.
In addition to choosing the right location, protective measures for the equipment are necessary. When the equipment is idle for an extended period, disconnect the power supply and cover it with a dust cover to prevent dust accumulation and foreign object ingress. This reduces cleaning tasks and component wear. Regularly check the equipment's condition to ensure it remains in good standby mode, ready for reuse at any time.
