一、儲罐檢測的周期
儲罐(guan)(guan)屬于特種(zhong)設備,需(xu)要定期(qi)進(jin)行檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce),以免留(liu)下(xia)安全(quan)隱患,儲罐(guan)(guan)的(de)(de)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)分為(wei)(wei)(wei)外部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)和(he)內(nei)(nei)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan),外部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)是指罐(guan)(guan)內(nei)(nei)貯存有介質(zhi)的(de)(de)情況下(xia),對(dui)(dui)罐(guan)(guan)的(de)(de)各個部(bu)(bu)(bu)位部(bu)(bu)(bu)件進(jin)行檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan),包(bao)括目視檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)、聲發射(she)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)、沉降觀測(ce)(ce)(ce)等;內(nei)(nei)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan)為(wei)(wei)(wei)罐(guan)(guan)內(nei)(nei)的(de)(de)介質(zhi)清空之后,對(dui)(dui)罐(guan)(guan)的(de)(de)各個部(bu)(bu)(bu)位部(bu)(bu)(bu)件進(jin)行檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan),包(bao)括底板背面(mian)腐蝕(shi)狀(zhuang)況檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)、焊縫無損檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)、真(zhen)空箱檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)等。儲罐(guan)(guan)的(de)(de)檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)周(zhou)期(qi)需(xu)要根據儲罐(guan)(guan)的(de)(de)技術使用(yong)條件來確(que)定和(he)計算,一(yi)(yi)般正常情況下(xia),檢(jian)(jian)(jian)(jian)(jian)(jian)測(ce)(ce)(ce)周(zhou)期(qi)為(wei)(wei)(wei):外部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)查每(mei)年(nian)至(zhi)(zhi)少一(yi)(yi)次,內(nei)(nei)部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)查每(mei)3年(nian)至(zhi)(zhi)少一(yi)(yi)次,全(quan)面(mian)檢(jian)(jian)(jian)(jian)(jian)(jian)查每(mei)6年(nian)至(zhi)(zhi)少一(yi)(yi)次。若儲罐(guan)(guan)使用(yong)年(nian)限(xian)達到15年(nian)以上,則每(mei)兩年(nian)則需(xu)進(jin)行一(yi)(yi)次內(nei)(nei)外部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)驗(yan)(yan),若使用(yong)年(nian)限(xian)達20年(nian),則每(mei)一(yi)(yi)年(nian)至(zhi)(zhi)少進(jin)行一(yi)(yi)次內(nei)(nei)外部(bu)(bu)(bu)檢(jian)(jian)(jian)(jian)(jian)(jian)查。
二、儲罐呼吸閥工作原理
儲罐(guan)(guan)(guan)(guan)呼(hu)吸(xi)(xi)閥(fa)是安(an)裝(zhuang)在儲罐(guan)(guan)(guan)(guan)頂(ding)上(shang)的(de)(de)(de)(de)部(bu)(bu)件,主(zhu)要用(yong)來(lai)滿足儲罐(guan)(guan)(guan)(guan)大小呼(hu)吸(xi)(xi)的(de)(de)(de)(de)通氣(qi)要求(qiu),一般(ban)由壓(ya)力(li)(li)閥(fa)和(he)真空(kong)閥(fa)兩(liang)部(bu)(bu)分組成(cheng),它的(de)(de)(de)(de)作(zuo)(zuo)(zuo)用(yong)是在一般(ban)情況下,保(bao)(bao)持(chi)儲罐(guan)(guan)(guan)(guan)的(de)(de)(de)(de)密閉性,在一定程度上(shang)減少儲罐(guan)(guan)(guan)(guan)內儲存(cun)物質的(de)(de)(de)(de)蒸發損耗;在必要時,它又能自動通氣(qi),調節平衡儲罐(guan)(guan)(guan)(guan)內外(wai)壓(ya)力(li)(li),對儲罐(guan)(guan)(guan)(guan)起到(dao)安(an)全作(zuo)(zuo)(zuo)用(yong),其工作(zuo)(zuo)(zuo)原理是:當罐(guan)(guan)(guan)(guan)內介質的(de)(de)(de)(de)壓(ya)力(li)(li)在呼(hu)吸(xi)(xi)閥(fa)的(de)(de)(de)(de)控制操作(zuo)(zuo)(zuo)壓(ya)力(li)(li)范圍之內時,呼(hu)吸(xi)(xi)閥(fa)不(bu)工作(zuo)(zuo)(zuo),保(bao)(bao)持(chi)儲罐(guan)(guan)(guan)(guan)的(de)(de)(de)(de)密封性;當往(wang)罐(guan)(guan)(guan)(guan)內補充介質,使罐(guan)(guan)(guan)(guan)內上(shang)部(bu)(bu)氣(qi)體空(kong)間的(de)(de)(de)(de)壓(ya)力(li)(li)升高(gao)(gao),達(da)到(dao)呼(hu)吸(xi)(xi)閥(fa)的(de)(de)(de)(de)操作(zuo)(zuo)(zuo)正壓(ya)時,壓(ya)力(li)(li)閥(fa)被頂(ding)開,氣(qi)體從呼(hu)吸(xi)(xi)閥(fa)呼(hu)出口逸出,使罐(guan)(guan)(guan)(guan)內壓(ya)力(li)(li)不(bu)在繼(ji)續增(zeng)高(gao)(gao);罐(guan)(guan)(guan)(guan)外(wai)的(de)(de)(de)(de)大氣(qi)將頂(ding)開呼(hu)吸(xi)(xi)閥(fa)的(de)(de)(de)(de)負(fu)壓(ya)閥(fa)盤,將儲罐(guan)(guan)(guan)(guan)中的(de)(de)(de)(de)空(kong)間和(he)大氣(qi)進行隔絕,從而保(bao)(bao)護儲罐(guan)(guan)(guan)(guan)的(de)(de)(de)(de)安(an)全。
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,讀作zhù guàn,是貯(zhu)(zhu)(zhu)存各(ge)(ge)種(zhong)(zhong)液體(ti)(ti)(ti)原(yuan)料、半成品或(huo)成品的(de)(de)設備,它(ta)和儲(chu)(chu)罐實際(ji)上(shang)并沒(mei)(mei)有(you)什么區別(bie),是同一物體(ti)(ti)(ti)的(de)(de)兩個不同稱呼。從字面意(yi)思上(shang)來看,貯(zhu)(zhu)(zhu)是儲(chu)(chu)存的(de)(de)意(yi)思,如貯(zhu)(zhu)(zhu)存、貯(zhu)(zhu)(zhu)藏、貯(zhu)(zhu)(zhu)積(ji);儲(chu)(chu)是積(ji)蓄的(de)(de)意(yi)思,如儲(chu)(chu)蓄、儲(chu)(chu)備、儲(chu)(chu)金、儲(chu)(chu)放(fang)、儲(chu)(chu)運,它(ta)們都有(you)存放(fang)的(de)(de)意(yi)思;通過查詢(xun)定義也發(fa)現二(er)者是差不多的(de)(de),貯(zhu)(zhu)(zhu)罐指用(yong)于貯(zhu)(zhu)(zhu)存各(ge)(ge)種(zhong)(zhong)液體(ti)(ti)(ti)原(yuan)料、半成品或(huo)成品的(de)(de)設備,儲(chu)(chu)罐是用(yong)以(yi)存放(fang)酸、醇、氣體(ti)(ti)(ti)等(deng)提煉(lian)的(de)(de)化學物質的(de)(de)設備。因此(ci),綜上(shang)所(suo)述,貯(zhu)(zhu)(zhu)罐和儲(chu)(chu)罐實際(ji)上(shang)是同一種(zhong)(zhong)物體(ti)(ti)(ti)的(de)(de)兩個不同稱呼,二(er)者實際(ji)上(shang)并沒(mei)(mei)有(you)什么區別(bie),用(yong)儲(chu)(chu)罐或(huo)貯(zhu)(zhu)(zhu)罐都可(ke)以(yi)。
