玻璃鋼儲罐維護方法

1、進(jin)(jin)(jin)(jin)入罐(guan)(guan)(guan)內(nei)維護(hu)，應先關閉所有進(jin)(jin)(jin)(jin)料閥門，放空(kong)并(bing)(bing)清洗罐(guan)(guan)(guan)體，經檢測確認罐(guan)(guan)(guan)內(nei)無有毒氣體，不缺氧(yang)時(shi)才能進(jin)(jin)(jin)(jin)入貯(zhu)(zhu)(zhu)罐(guan)(guan)(guan)，進(jin)(jin)(jin)(jin)入罐(guan)(guan)(guan)內(nei)應穿(chuan)軟底(di)鞋，綁上安全(quan)(quan)帶并(bing)(bing)將安全(quan)(quan)帶另一端系于罐(guan)(guan)(guan)頂，注意罐(guan)(guan)(guan)內(nei)通風。進(jin)(jin)(jin)(jin)入罐(guan)(guan)(guan)內(nei)操作，必(bi)須有人(ren)員(yuan)在(zai)罐(guan)(guan)(guan)外(wai)(wai)監(jian)控下進(jin)(jin)(jin)(jin)行(xing)。要防止工器具撞(zhuang)傷罐(guan)(guan)(guan)壁(bi)(bi)，使用(yong)(yong)梯子(zi)、金屬(shu)件等于罐(guan)(guan)(guan)壁(bi)(bi)接(jie)觸部(bu)分要加(jia)軟質(zhi)墊，保護(hu)內(nei)壁(bi)(bi)不被(bei)劃(hua)裂、挫傷。2、貯(zhu)(zhu)(zhu)罐(guan)(guan)(guan)的外(wai)(wai)爬梯、護(hu)籠、護(hu)欄(lan)在(zai)攀爬前(qian)應仔(zi)細(xi)檢查是否(fou)安全(quan)(quan)可靠，有異常情況嚴禁(jin)攀爬使用(yong)(yong)。3、維修時(shi)不可在(zai)罐(guan)(guan)(guan)頂隨意加(jia)載，也不準在(zai)接(jie)管上施加(jia)外(wai)(wai)力。4、戶(hu)外(wai)(wai)使用(yong)(yong)貯(zhu)(zhu)(zhu)罐(guan)(guan)(guan)使用(yong)(yong)多年后會(hui)因外(wai)(wai)表(biao)層(ceng)老化(hua)，造成樹脂(zhi)層(ceng)剝落或纖維外(wai)(wai)露。建議每(mei)二(er)、三年應在(zai)罐(guan)(guan)(guan)外(wai)(wai)表(biao)面涂刷(shua)油(you)漆(qi)或樹脂(zhi)，以防老化(hua)，延長使用(yong)(yong)壽(shou)命。
