Nuair a úsáidimid gléas áirithe, b'fhéidir go dtiocfaidhimid ar an ngléas a bábhlaíonn go hiondúil le caitheamh agus creimeadh, rud a chiallaíonn go bhfuil cuid de na compoennataí an ghlas-líneach laige le creimeadh. Nuair a bhíonn fan lárnaíoch á úsáid, beidh na húsáideoirí ag fáil go bhfuil dhá chuid bhánta tábhachtacha sa trealamh, sé sin na gloiní agus an volute, agus tá an feiniméan seo go háirithe le feiceáil i ngníomhaireachtaí fuinnimh.
Firstly, I would like to introduce the wear and tear of the blades. The wear of blades varies among different devices. For example, some centrifugal fans have severe wear on their forward blades. The main areas of wear are the blade inlet, outlet, and near the root of the rear disc. Some fans also use radial straight plate lanna . Tá an caitheamh a thaispeánann an cineál seo lann serrated den chuid is mó, agus tá an caitheamh comhchruinnithe den chuid is mó ag an asraon lann, ag lagú de réir a chéile as an asraon lann .
In addition to the above two situations, in practical work, there are also some centrifugal fans that use backward wing blades. For this type of blade wear, the most severe areas are the outlet section near the rear disc and the blade head. If the blade head is worn, the blade cavity is easily invaded by coal ash, gradually causing the rotor balance to be disrupted and causing problems mar chreathadh lucht leanúna .
