When the DECENT fan equipment starts to work, the vibration of the bearing part is very small, but as the running time increases, the dust in the fan will adhere to the impeller unevenly, gradually destroy the dynamic balance of the fan, and gradually increase the vibration of the bearing. When the allowable value of the fan reaches 11mm/s, it must be shut down for repair (remove dust accumulation and redo the dynamic balance).
Every time the motor is stopped, the oil and dust of the motor itself and the motor cooling impeller should be cleaned, so that the motor itself can be cooled by 2-4 °C, so that the motor can dissipate well.
During normal operation, add butter to the fan bearing once within 120-150 (5-6 days) hours, and make a record to ensure that the oil is in place and the gear oil tank to ensure the normal oil level.
The equipment clearance is small, and the impeller will be stained with sludge in the air during normal operation for a long time, resulting in large friction between the impellers. . Therefore, when conveying air medium, its dust content should not be greater than 100mg/m3, and you should be diligent in replacing the fan inlet filter cloth (replace every week according to the air volume), clean the fan room to ensure the purity of the air material, and clean the fan impeller every six months. , and keep records.
When the DECENT fan equipment is in normal operation, add butter to the fan bearing once within 120-150 (5-6 days) hours, and make a record to ensure that the oil is in place and the gear oil tank to ensure the normal oil level.
Regularly remove impurities such as dust and dirt on the impeller. Especially when the fan is used to transport media containing viscous substances (such as oil fume) or dusty medium, the impeller parts should be cleaned once a month. Otherwise, the accumulated impurities will destroy the dynamic balance of the impeller, resulting in increased vibration of the fan and damage to the parts.
