防護等(deng)級(ji)為(wei)達到：在有水(shui)(shui)或高濕度或灰(hui)塵(chen)較大(da)的(de)環(huan)(huan)(huan)境使(shi)用(yong)(yong)未做(zuo)防水(shui)(shui)防塵(chen)設計的(de)導(dao)(dao)電(dian)(dian)(dian)滑(hua)(hua)(hua)環(huan)(huan)(huan)，使(shi)得滑(hua)(hua)(hua)環(huan)(huan)(huan)內部進水(shui)(shui)，引起內部短路，或大(da)量灰(hui)塵(chen)進入滑(hua)(hua)(hua)環(huan)(huan)(huan)造成(cheng)(cheng)滑(hua)(hua)(hua)環(huan)(huan)(huan)失(shi)效。滑(hua)(hua)(hua)環(huan)(huan)(huan)過(guo)載燒毀：滑(hua)(hua)(hua)環(huan)(huan)(huan)允許的(de)大(da)電(dian)(dian)(dian)流是(shi)根據導(dao)(dao)電(dian)(dian)(dian)環(huan)(huan)(huan)的(de)截面(mian)積(ji)、電(dian)(dian)(dian)刷(shua)接(jie)觸(chu)面(mian)積(ji)，電(dian)(dian)(dian)刷(shua)與接(jie)觸(chu)面(mian)的(de)壓(ya)力，海虞船用(yong)(yong)滑(hua)(hua)(hua)環(huan)(huan)(huan)，轉(zhuan)速等(deng)綜合因素決定的(de)可運行(xing)的(de)電(dian)(dian)(dian)流值。超出該值，導(dao)(dao)電(dian)(dian)(dian)滑(hua)(hua)(hua)環(huan)(huan)(huan)就有可能輕則會有發熱，重則接(jie)觸(chu)面(mian)打火，甚至電(dian)(dian)(dian)刷(shua)與導(dao)(dao)電(dian)(dian)(dian)環(huan)(huan)(huan)之(zhi)間形成(cheng)(cheng)焊(han)接(jie)點(dian)。雖然(ran)導(dao)(dao)電(dian)(dian)(dian)滑(hua)(hua)(hua)環(huan)(huan)(huan)的(de)設計階段會考(kao)慮一(yi)定的(de)系(xi)數(shu)，但(dan)是(shi)仍然(ran)建議(yi)客戶按(an)實際使(shi)用(yong)(yong)的(de)大(da)電(dian)(dian)(dian)流提供給滑(hua)(hua)(hua)環(huan)(huan)(huan)生產廠家。

轉動：如果滑(hua)環(huan)本身存在(zai)晃動、轉動有異響或卡住，這樣的(de)(de)產(chan)品(pin)裝在(zai)設備上就會存在(zai)很大(da)的(de)(de)隱(yin)患；試(shi)裝：滑(hua)環(huan)產(chan)品(pin)在(zai)結構設計中是十分(fen)嚴謹的(de)(de)，尺寸的(de)(de)配合(he)也要(yao)求十分(fen)準(zhun)確，與設備的(de)(de)配合(he)尺寸也一定(ding)要(yao)合(he)適，太(tai)松(song)或太(tai)緊都會影(ying)響產(chan)品(pin)的(de)(de)使用(yong)。檢(jian)測(ce)還可采用(yong)儀(yi)器測(ce)試(shi)查(cha)看質量，我們會隨(sui)產(chan)品(pin)提(ti)供檢(jian)驗報告(gao)，檢(jian)驗報告(gao)能體現重要(yao)數據(ju)和參數，您可以根據(ju)這份報告(gao)進行檢(jian)測(ce)。
