一、儲罐檢測的周期
儲罐(guan)(guan)(guan)屬于(yu)特種(zhong)設(she)備(bei),需要(yao)定期進行檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce),以免留下(xia)安全隱患,儲罐(guan)(guan)(guan)的檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)分為外部(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)和內(nei)部(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan),外部(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)是指罐(guan)(guan)(guan)內(nei)貯存(cun)有介質的情(qing)況下(xia),對(dui)罐(guan)(guan)(guan)的各個部(bu)位部(bu)件進行檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan),包括目(mu)視檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)、聲發射檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)、沉(chen)降觀測(ce)(ce)(ce)等(deng);內(nei)部(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)為罐(guan)(guan)(guan)內(nei)的介質清空(kong)(kong)之后,對(dui)罐(guan)(guan)(guan)的各個部(bu)位部(bu)件進行檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan),包括底板背面(mian)腐蝕狀況檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)、焊縫無損檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)、真空(kong)(kong)箱檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)等(deng)。儲罐(guan)(guan)(guan)的檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)周期需要(yao)根據儲罐(guan)(guan)(guan)的技術使用(yong)條件來確定和計算,一般正(zheng)常情(qing)況下(xia),檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)周期為:外部(bu)檢(jian)(jian)(jian)(jian)(jian)查(cha)每(mei)(mei)年(nian)至(zhi)(zhi)少(shao)(shao)一次(ci),內(nei)部(bu)檢(jian)(jian)(jian)(jian)(jian)查(cha)每(mei)(mei)3年(nian)至(zhi)(zhi)少(shao)(shao)一次(ci),全面(mian)檢(jian)(jian)(jian)(jian)(jian)查(cha)每(mei)(mei)6年(nian)至(zhi)(zhi)少(shao)(shao)一次(ci)。若儲罐(guan)(guan)(guan)使用(yong)年(nian)限達到15年(nian)以上,則每(mei)(mei)兩(liang)年(nian)則需進行一次(ci)內(nei)外部(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan),若使用(yong)年(nian)限達20年(nian),則每(mei)(mei)一年(nian)至(zhi)(zhi)少(shao)(shao)進行一次(ci)內(nei)外部(bu)檢(jian)(jian)(jian)(jian)(jian)查(cha)。
二、儲罐呼吸閥工作原理
儲(chu)(chu)罐(guan)呼吸閥(fa)(fa)是安(an)裝在(zai)(zai)儲(chu)(chu)罐(guan)頂(ding)上(shang)(shang)的(de)(de)部件,主要用(yong)(yong)來滿(man)足儲(chu)(chu)罐(guan)大小(xiao)呼吸的(de)(de)通氣(qi)(qi)要求(qiu),一(yi)般由壓(ya)力(li)(li)閥(fa)(fa)和(he)真(zhen)空(kong)(kong)(kong)閥(fa)(fa)兩部分組成,它(ta)的(de)(de)作(zuo)用(yong)(yong)是在(zai)(zai)一(yi)般情況下(xia),保(bao)持(chi)(chi)儲(chu)(chu)罐(guan)的(de)(de)密(mi)閉性(xing),在(zai)(zai)一(yi)定程度上(shang)(shang)減少儲(chu)(chu)罐(guan)內(nei)(nei)(nei)儲(chu)(chu)存物質的(de)(de)蒸(zheng)發損耗;在(zai)(zai)必(bi)要時(shi),它(ta)又能自動通氣(qi)(qi),調(diao)節(jie)平衡儲(chu)(chu)罐(guan)內(nei)(nei)(nei)外壓(ya)力(li)(li),對儲(chu)(chu)罐(guan)起到安(an)全(quan)(quan)作(zuo)用(yong)(yong),其(qi)工作(zuo)原理是:當(dang)罐(guan)內(nei)(nei)(nei)介(jie)質的(de)(de)壓(ya)力(li)(li)在(zai)(zai)呼吸閥(fa)(fa)的(de)(de)控制操作(zuo)壓(ya)力(li)(li)范圍之內(nei)(nei)(nei)時(shi),呼吸閥(fa)(fa)不工作(zuo),保(bao)持(chi)(chi)儲(chu)(chu)罐(guan)的(de)(de)密(mi)封性(xing);當(dang)往罐(guan)內(nei)(nei)(nei)補(bu)充介(jie)質,使罐(guan)內(nei)(nei)(nei)上(shang)(shang)部氣(qi)(qi)體空(kong)(kong)(kong)間的(de)(de)壓(ya)力(li)(li)升高,達到呼吸閥(fa)(fa)的(de)(de)操作(zuo)正壓(ya)時(shi),壓(ya)力(li)(li)閥(fa)(fa)被頂(ding)開,氣(qi)(qi)體從呼吸閥(fa)(fa)呼出口逸出,使罐(guan)內(nei)(nei)(nei)壓(ya)力(li)(li)不在(zai)(zai)繼續增(zeng)高;罐(guan)外的(de)(de)大氣(qi)(qi)將頂(ding)開呼吸閥(fa)(fa)的(de)(de)負壓(ya)閥(fa)(fa)盤,將儲(chu)(chu)罐(guan)中的(de)(de)空(kong)(kong)(kong)間和(he)大氣(qi)(qi)進行隔絕,從而保(bao)護儲(chu)(chu)罐(guan)的(de)(de)安(an)全(quan)(quan)。
三、儲罐類型有哪些
儲罐的種類眾多,按照不同的分類方法可分為不同類型:1、按位置歸類:可分成地上儲罐、海上儲罐、半地下儲罐、地下儲罐、海底儲罐等。2、按油品歸類:可分成原油儲罐、食用油罐、潤滑油罐、燃油儲罐、消防水罐等。3、按用途歸類:可分成原料罐、成品罐、中間產品罐、廢料罐等。4、按方式歸類:可分成立式儲罐、球形儲罐、雙曲線儲罐(滴形儲罐)、臥式儲罐、懸鏈式儲罐(無力矩儲罐)等。5、按溫度歸類:常溫儲罐、低溫儲罐、高溫儲罐。6、按壓力歸類:常壓儲罐、低壓儲罐、高壓儲罐。7、按儲罐材料歸類:聚乙烯儲罐、橡膠儲罐、玻璃鋼儲罐、陶瓷儲罐、聚丙烯儲罐、不銹鋼儲罐等。8、按容量歸類:?50m3以上為大型儲罐,多為立式儲罐;50m3以下的為小型儲罐。如果您需要購買儲罐,可以先來了解一下儲罐十大品牌。
四、貯罐和儲罐的區別
貯(zhu)(zhu)(zhu)罐(guan),讀作zhù guàn,是(shi)貯(zhu)(zhu)(zhu)存各種(zhong)液體(ti)原(yuan)料(liao)、半(ban)成品或(huo)成品的(de)(de)設備,它和(he)儲(chu)罐(guan)實(shi)(shi)際(ji)上并沒有(you)什么區別(bie),是(shi)同一(yi)物體(ti)的(de)(de)兩個(ge)不同稱呼。從字面(mian)意(yi)(yi)思(si)(si)上來看,貯(zhu)(zhu)(zhu)是(shi)儲(chu)存的(de)(de)意(yi)(yi)思(si)(si),如(ru)貯(zhu)(zhu)(zhu)存、貯(zhu)(zhu)(zhu)藏、貯(zhu)(zhu)(zhu)積;儲(chu)是(shi)積蓄(xu)的(de)(de)意(yi)(yi)思(si)(si),如(ru)儲(chu)蓄(xu)、儲(chu)備、儲(chu)金、儲(chu)放(fang)、儲(chu)運,它們都(dou)有(you)存放(fang)的(de)(de)意(yi)(yi)思(si)(si);通過查詢定(ding)義(yi)也發(fa)現二(er)者是(shi)差不多的(de)(de),貯(zhu)(zhu)(zhu)罐(guan)指(zhi)用于貯(zhu)(zhu)(zhu)存各種(zhong)液體(ti)原(yuan)料(liao)、半(ban)成品或(huo)成品的(de)(de)設備,儲(chu)罐(guan)是(shi)用以存放(fang)酸、醇、氣體(ti)等(deng)提煉(lian)的(de)(de)化學物質的(de)(de)設備。因此,綜(zong)上所述,貯(zhu)(zhu)(zhu)罐(guan)和(he)儲(chu)罐(guan)實(shi)(shi)際(ji)上是(shi)同一(yi)種(zhong)物體(ti)的(de)(de)兩個(ge)不同稱呼,二(er)者實(shi)(shi)際(ji)上并沒有(you)什么區別(bie),用儲(chu)罐(guan)或(huo)貯(zhu)(zhu)(zhu)罐(guan)都(dou)可以。
