一、儲罐檢測的周期
儲罐(guan)屬于特種設(she)備,需(xu)要(yao)定期進(jin)(jin)行(xing)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce),以免留下安全隱患(huan),儲罐(guan)的(de)(de)(de)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)分為(wei)外(wai)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)和內部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan),外(wai)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)是指罐(guan)內貯存有介質的(de)(de)(de)情(qing)況(kuang)(kuang)下,對(dui)(dui)罐(guan)的(de)(de)(de)各個部(bu)(bu)(bu)位(wei)(wei)部(bu)(bu)(bu)件(jian)進(jin)(jin)行(xing)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan),包括(kuo)目視檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)、聲發射檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)、沉降觀測(ce)(ce)(ce)等;內部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)為(wei)罐(guan)內的(de)(de)(de)介質清(qing)空之(zhi)后,對(dui)(dui)罐(guan)的(de)(de)(de)各個部(bu)(bu)(bu)位(wei)(wei)部(bu)(bu)(bu)件(jian)進(jin)(jin)行(xing)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan),包括(kuo)底板背面腐蝕(shi)狀況(kuang)(kuang)檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)、焊縫無損檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)、真空箱檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)等。儲罐(guan)的(de)(de)(de)檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)周(zhou)期需(xu)要(yao)根據儲罐(guan)的(de)(de)(de)技術(shu)使(shi)用(yong)條件(jian)來確定和計算,一般正常(chang)情(qing)況(kuang)(kuang)下,檢(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)周(zhou)期為(wei):外(wai)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)查每年(nian)(nian)至少一次(ci),內部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)查每3年(nian)(nian)至少一次(ci),全面檢(jian)(jian)(jian)(jian)(jian)查每6年(nian)(nian)至少一次(ci)。若(ruo)儲罐(guan)使(shi)用(yong)年(nian)(nian)限達(da)到15年(nian)(nian)以上,則(ze)每兩年(nian)(nian)則(ze)需(xu)進(jin)(jin)行(xing)一次(ci)內外(wai)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan),若(ruo)使(shi)用(yong)年(nian)(nian)限達(da)20年(nian)(nian),則(ze)每一年(nian)(nian)至少進(jin)(jin)行(xing)一次(ci)內外(wai)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)查。
二、儲罐呼吸閥工作原理
儲罐(guan)(guan)(guan)(guan)(guan)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)是(shi)安(an)裝在(zai)(zai)儲罐(guan)(guan)(guan)(guan)(guan)頂上的(de)(de)(de)(de)(de)(de)部件,主要用(yong)來滿足儲罐(guan)(guan)(guan)(guan)(guan)大小呼(hu)(hu)吸(xi)(xi)的(de)(de)(de)(de)(de)(de)通氣(qi)(qi)要求(qiu),一(yi)(yi)般由壓力(li)(li)閥(fa)(fa)和真空(kong)閥(fa)(fa)兩部分組成(cheng),它的(de)(de)(de)(de)(de)(de)作用(yong)是(shi)在(zai)(zai)一(yi)(yi)般情況下,保(bao)(bao)持儲罐(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)(de)密閉性,在(zai)(zai)一(yi)(yi)定程(cheng)度上減少儲罐(guan)(guan)(guan)(guan)(guan)內(nei)儲存(cun)物質(zhi)的(de)(de)(de)(de)(de)(de)蒸(zheng)發損耗;在(zai)(zai)必要時,它又(you)能自動通氣(qi)(qi),調節(jie)平(ping)衡儲罐(guan)(guan)(guan)(guan)(guan)內(nei)外壓力(li)(li),對(dui)儲罐(guan)(guan)(guan)(guan)(guan)起到安(an)全(quan)作用(yong),其工作原理是(shi):當罐(guan)(guan)(guan)(guan)(guan)內(nei)介質(zhi)的(de)(de)(de)(de)(de)(de)壓力(li)(li)在(zai)(zai)呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)的(de)(de)(de)(de)(de)(de)控制操作壓力(li)(li)范(fan)圍之內(nei)時,呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)不工作,保(bao)(bao)持儲罐(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)(de)密封性;當往罐(guan)(guan)(guan)(guan)(guan)內(nei)補充(chong)介質(zhi),使(shi)罐(guan)(guan)(guan)(guan)(guan)內(nei)上部氣(qi)(qi)體空(kong)間的(de)(de)(de)(de)(de)(de)壓力(li)(li)升高(gao),達到呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)的(de)(de)(de)(de)(de)(de)操作正壓時,壓力(li)(li)閥(fa)(fa)被(bei)頂開,氣(qi)(qi)體從呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)呼(hu)(hu)出口逸(yi)出,使(shi)罐(guan)(guan)(guan)(guan)(guan)內(nei)壓力(li)(li)不在(zai)(zai)繼續增高(gao);罐(guan)(guan)(guan)(guan)(guan)外的(de)(de)(de)(de)(de)(de)大氣(qi)(qi)將頂開呼(hu)(hu)吸(xi)(xi)閥(fa)(fa)的(de)(de)(de)(de)(de)(de)負壓閥(fa)(fa)盤(pan),將儲罐(guan)(guan)(guan)(guan)(guan)中(zhong)的(de)(de)(de)(de)(de)(de)空(kong)間和大氣(qi)(qi)進行隔(ge)絕,從而保(bao)(bao)護儲罐(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)(de)安(an)全(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)罐,讀作zhù guàn,是貯(zhu)(zhu)存(cun)(cun)各種(zhong)液(ye)體(ti)(ti)原料(liao)、半成品(pin)或成品(pin)的(de)設(she)備,它(ta)(ta)和儲罐實際上并沒有(you)(you)什(shen)(shen)么區別,是同(tong)一物(wu)體(ti)(ti)的(de)兩個(ge)不(bu)同(tong)稱呼(hu)。從字面(mian)意(yi)思上來看,貯(zhu)(zhu)是儲存(cun)(cun)的(de)意(yi)思,如(ru)貯(zhu)(zhu)存(cun)(cun)、貯(zhu)(zhu)藏、貯(zhu)(zhu)積;儲是積蓄(xu)的(de)意(yi)思,如(ru)儲蓄(xu)、儲備、儲金、儲放(fang)、儲運,它(ta)(ta)們都有(you)(you)存(cun)(cun)放(fang)的(de)意(yi)思;通過查詢定(ding)義也發(fa)現(xian)二者(zhe)是差(cha)不(bu)多(duo)的(de),貯(zhu)(zhu)罐指用于(yu)貯(zhu)(zhu)存(cun)(cun)各種(zhong)液(ye)體(ti)(ti)原料(liao)、半成品(pin)或成品(pin)的(de)設(she)備,儲罐是用以存(cun)(cun)放(fang)酸、醇(chun)、氣體(ti)(ti)等提煉(lian)的(de)化學物(wu)質(zhi)的(de)設(she)備。因此(ci),綜上所述,貯(zhu)(zhu)罐和儲罐實際上是同(tong)一種(zhong)物(wu)體(ti)(ti)的(de)兩個(ge)不(bu)同(tong)稱呼(hu),二者(zhe)實際上并沒有(you)(you)什(shen)(shen)么區別,用儲罐或貯(zhu)(zhu)罐都可以。
