談談CDLF多級泵的安全使用要點

　　一、選購CDLF多級泵時應注意其類型、流量和揚程。如選用的規格不恰當，將無法獲得滿足的出水量，不能發揮機組的效率。另外，還應搞清電機的旋轉方向，某些類型的CDLF多級泵正轉和回轉時皆可出水，但回轉時出水量小、電流大，其回轉會損壞電機繞組。為防止CDLF多級泵在水(shui)下工作時漏電(dian)而(er)引發觸電(dian)事端，應裝漏電(dian)保護開關。

　　二、安裝(zhuang)CDLF多(duo)級(ji)泵(beng)時，電(dian)纜(lan)(lan)線(xian)要(yao)架空，電(dian)源(yuan)線(xian)不(bu)要(yao)太長(chang)。機(ji)組下水時切勿使電(dian)纜(lan)(lan)受力，避免引(yin)起電(dian)源(yuan)線(xian)開裂。CDLF多(duo)級(ji)泵(beng)不(bu)要(yao)沉入泥中(zhong)，否則(ze)會導致散(san)熱不(bu)良而(er)燒壞(huai)電(dian)機(ji)繞組。

　　三、盡量避免在低壓時(shi)開機(ji)。電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓與(yu)額外電(dian)(dian)(dian)(dian)(dian)(dian)壓不(bu)行相差(cha)10%，電(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)高會(hui)(hui)引起電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)過(guo)熱而燒壞(huai)繞(rao)組(zu)，電(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)低則電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)轉(zhuan)速下(xia)降，如達不(bu)到額外轉(zhuan)速的70%時(shi)，發動(dong)離(li)心開關會(hui)(hui)閉(bi)合(he)，造成(cheng)發動(dong)繞(rao)組(zu)長時(shi)間通電(dian)(dian)(dian)(dian)(dian)(dian)而發熱乃至燒壞(huai)繞(rao)組(zu)和電(dian)(dian)(dian)(dian)(dian)(dian)容器。不(bu)要頻繁地開關電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)，這是(shi)由于電(dian)(dian)(dian)(dian)(dian)(dian)泵停轉(zhuan)時(shi)會(hui)(hui)產生(sheng)回(hui)流，若立即開機(ji)，會(hui)(hui)使電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)負載發動(dong)，導致發動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)流過(guo)大而燒壞(huai)繞(rao)組(zu)。

　　四(si)、切莫(mo)讓CDLF多級泵長期超負荷工(gong)(gong)(gong)作(zuo)(zuo)(zuo)，不(bu)要抽含(han)沙量大的(de)水，電泵脫水工(gong)(gong)(gong)作(zuo)(zuo)(zuo)的(de)時(shi)間不(bu)宜(yi)過長，避免使(shi)(shi)電機(ji)過熱而燒毀。機(ji)組(zu)在工(gong)(gong)(gong)作(zuo)(zuo)(zuo)中，操作(zuo)(zuo)(zuo)者有必要隨(sui)時(shi)調查其工(gong)(gong)(gong)作(zuo)(zuo)(zuo)電壓和(he)電流是(shi)否在銘牌(pai)上規定(ding)的(de)數值(zhi)內，若不(bu)契合應(ying)使(shi)(shi)電機(ji)停止工(gong)(gong)(gong)作(zuo)(zuo)(zuo)，找出原因(yin)并(bing)排(pai)除故障。

　　五、平常多查看(kan)電機，如發現下蓋有裂紋、橡膠密封環(huan)損壞或失效(xiao)等，應及時更換(huan)或修正，以防水進入機器。
