Roots FansIn the use of the process of meeting the fault is inevitable, then what are the common faults of Roots fan? On this issue, Roots fan small editor to take you to understand.
1. High current
If the mechanical part of the Roots fan rattling, temperature, vibration is normal, just some dull, higher current, generally in and out of the wind is unfavorable, the inlet filter, shell ash collection, out of the pipeline valves are not fully open and clogging of the main reasons.
2. Bearing heat
Roots fan bearing heat in operation is mostly due to bearing damage or poor lubrication and belt tension is too large, if the bearing failure, there must be accompanied by a loud noise, a listen to know.
3. Abnormal gearbox rattling
Unusual gearbox rattling is related to tooth wear and poor lubrication, and if there is uneven impact, it is a characteristic of key or locating pin failure, or there may be bearing damage or broken teeth.
4. Abnormal noise in the machine cavity
If there is a friction sound in the cavity, it may be that there is a problem with the positioning of the bearings; if it is an impact, it is usually that the bearings have been damaged, the center distance of the impeller has changed, and the side of the impeller is not parallel to the wall. There is another situation, it may be the impeller stuck on the foreign body, but the chances are not much.
5. Abnormalities in the drive belt
If the transmission belt is worn out and slagged, it may be that the belt is in contact with the bottom of the groove, the two belt theories are not parallel or the corresponding groove is not in a plane, and the wheel is rough.
6. High fan current, overpressure operation
Fan current, and overpressure, mostly belong to the system pipeline is not smooth; here I mainly want to remind, the valve must be calibrated, overpressure bleed, strictly prohibit the fan overpressure operation.
