Roots fan maintenance details
Roots Fans在維修的過程中有一些細節(jié)是大家需要知道的，關于這個問題羅茨風機小編帶你了解一下。
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.傳動帶出現異常
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.
3.軸承發(fā)熱
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.
4.風機電流大，超壓運行
風機電流大，且超壓，多屬于系統(tǒng)管道不暢；在此主要想提醒一下，安全閥一定校準，超壓放氣，嚴禁風機超壓運行。
5.齒輪箱響聲異常
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.
6.機腔內有異常響聲
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.
