池州泵用池州機械密封的O型圈為什么會泄漏失效？一般來說，原因可以從泵的池州機械密封的(de)安裝、使用(yong)條件、運行速度和停機故障(zhang)等方面進(jin)行監測原(yuan)因。

　　一、安裝靜(jing)態試驗時的泄漏？

　　池州泵用池州機械密封安裝調試后，一般需要(yao)進(jin)行(xing)靜(jing)(jing)(jing)(jing)態試驗(yan)，觀察(cha)泄(xie)漏(lou)情(qing)況。如(ru)果(guo)泄(xie)漏(lou)量(liang)小，動(dong)(dong)(dong)環(huan)(huan)(huan)(huan)(huan)(huan)或靜(jing)(jing)(jing)(jing)環(huan)(huan)(huan)(huan)(huan)(huan)密(mi)(mi)封圈有(you)問(wen)(wen)題(ti)(ti)；當泄(xie)漏(lou)量(liang)較(jiao)大時，表明(ming)(ming)(ming)動(dong)(dong)(dong)靜(jing)(jing)(jing)(jing)環(huan)(huan)(huan)(huan)(huan)(huan)摩(mo)擦副之間存在(zai)問(wen)(wen)題(ti)(ti)。在(zai)初步觀察(cha)泄(xie)漏(lou)量(liang)和判斷泄(xie)漏(lou)位置的(de)基(ji)礎(chu)上，手動(dong)(dong)(dong)轉動(dong)(dong)(dong)O形圈進(jin)行(xing)觀察(cha)。如(ru)果(guo)泄(xie)漏(lou)量(liang)沒有(you)明(ming)(ming)(ming)顯變化，說明(ming)(ming)(ming)動(dong)(dong)(dong)靜(jing)(jing)(jing)(jing)環(huan)(huan)(huan)(huan)(huan)(huan)密(mi)(mi)封有(you)問(wen)(wen)題(ti)(ti)；如(ru)果(guo)轉動(dong)(dong)(dong)時泄(xie)漏(lou)量(liang)有(you)明(ming)(ming)(ming)顯變化，可以斷定(ding)動(dong)(dong)(dong)環(huan)(huan)(huan)(huan)(huan)(huan)和靜(jing)(jing)(jing)(jing)環(huan)(huan)(huan)(huan)(huan)(huan)的(de)摩(mo)擦副有(you)問(wen)(wen)題(ti)(ti)；如(ru)果(guo)是沿軸向噴(pen)漏(lou)介(jie)質，動(dong)(dong)(dong)環(huan)(huan)(huan)(huan)(huan)(huan)密(mi)(mi)封環(huan)(huan)(huan)(huan)(huan)(huan)(O型環(huan)(huan)(huan)(huan)(huan)(huan))存在(zai)很多(duo)問(wen)(wen)題(ti)(ti)，如(ru)果(guo)是周圍(wei)噴(pen)漏(lou)介(jie)質或從水冷孔漏(lou)出，多(duo)半是靜(jing)(jing)(jing)(jing)環(huan)(huan)(huan)(huan)(huan)(huan)密(mi)(mi)封環(huan)(huan)(huan)(huan)(huan)(huan)失效(xiao)。

　　二(er)、試運(yun)的滲漏(lou)？

　　靜態試驗后，O型圈高速旋轉產生的離心力會抑制介質的泄漏。因此，試運行時池州機械密封的泄漏，基本上是在軸與端(duan)蓋(gai)之(zhi)間的密封(feng)失效消(xiao)除后(hou)，動靜環之(zhi)間的摩擦副損壞造成的。

　　三(san)、停(ting)(ting)電還是停(ting)(ting)機？

　　離心泵(beng)正常運行過程中(zhong)O型圈(quan)突然泄漏(lou)，如果不及時(shi)發現(xian)，往往會導致(zhi)重大事(shi)故(gu)或損失，應引(yin)起(qi)重視并(bing)采取有(you)效措施(shi)。特別是突然停電(dian)造成的事(shi)故(gu)，必須準備好電(dian)源O型圈(quan)。

　　最后提醒大家，泵使用池州機械密封時，一(yi)次泄漏和二(er)次泄漏是有區別(bie)的(de)。只要仔細觀察，熟(shu)悉結構(gou)，就能做(zuo)出正確的(de)判斷。
