耐(nai)腐(fu)蝕化工泵(beng)是工(gong)業(ye)生產中，對使(shi)用(yong)泵的(de)統稱，耐腐蝕化工泵常見的(de)有(you)耐(nai)腐(fu)蝕(shi)(shi)氟(fu)塑(su)料化工(gong)(gong)泵(beng)(beng)，耐(nai)腐(fu)蝕(shi)(shi)不銹鋼化工(gong)(gong)泵(beng)(beng)，液下化工(gong)(gong)泵(beng)(beng)等等，用戶在使用耐(nai)腐(fu)蝕(shi)(shi)化工(gong)(gong)泵(beng)(beng)時(shi)，出現泄漏(lou)(lou)是很麻(ma)煩的(de)問題，需(xu)要解決這一(yi)問題首先需(xu)找出泄漏(lou)(lou)點，對于化工(gong)(gong)泵(beng)(beng)密(mi)(mi)封墊(dian)片和密(mi)(mi)封裝置失(shi)效是化工(gong)(gong)泵(beng)(beng)泄漏(lou)(lou)的(de)直接原因(yin)，下面詳細介(jie)紹化工(gong)(gong)泵(beng)(beng)密(mi)(mi)封失(shi)效原因(yin)有(you)哪些(xie)：在化工(gong)(gong)泵(beng)(beng)中，由于所輸送介(jie)質(zhi)具(ju)有(you)腐(fu)蝕(shi)(shi)性(xing)，一(yi)旦密(mi)(mi)封墊(dian)圈(quan)失(shi)效，危害有(you)非常大(da)。所以，要十(shi)分重視(shi)耐(nai)腐(fu)蝕(shi)(shi)泵(beng)(beng)的(de)密(mi)(mi)封性(xing)，保證化工(gong)(gong)泵(beng)(beng)安全、正常工(gong)(gong)作。

1.耐腐蝕(shi)泵墊(dian)片(pian)的材質(zhi)(zhi)(zhi)與所輸送(song)的介質(zhi)(zhi)(zhi)不相適(shi)應。由(you)于(yu)化(hua)(hua)工泵(beng)所輸送(song)化(hua)(hua)工產品化(hua)(hua)學性質(zhi)(zhi)(zhi)的多樣性，以(yi)及為提高燃(ran)(ran)油的燃(ran)(ran)燒值，或改變(bian)其(qi)燃(ran)(ran)燒后的生(sheng)(sheng)成物，而(er)在燃(ran)(ran)油中增(zeng)加(jia)(jia)入了一些少量的添加(jia)(jia)劑后，使燃(ran)(ran)油的某些性質(zhi)(zhi)(zhi)發生(sheng)(sheng)變(bian)化(hua)(hua)。所以(yi)選(xuan)擇和輸送(song)介質(zhi)(zhi)(zhi)相適(shi)的墊(dian)片(pian)材質(zhi)(zhi)(zhi)并非易事，因而(er)也經常發生(sheng)(sheng)由(you)于(yu)不相適(shi)應，而(er)使化(hua)(hua)工泵(beng)墊(dian)片(pian)發生(sheng)(sheng)侵蝕(shi)而(er)產生(sheng)(sheng)泄(xie)漏(lou)的現象(xiang)。

2.作用(yong)在(zai)化工(gong)泵密(mi)封(feng)(feng)墊(dian)片(pian)上(shang)的(de)(de)壓(ya)(ya)力(li)不(bu)(bu)足。由(you)于(yu)密(mi)封(feng)(feng)面(mian)(mian)上(shang)總(zong)是存在(zai)著(zhu)微觀(guan)的(de)(de)凹(ao)凸不(bu)(bu)平，有時還在(zai)密(mi)封(feng)(feng)面(mian)(mian)上(shang)加工(gong)出若(ruo)干(gan)環形溝(gou)槽(cao)，若(ruo)保(bao)證密(mi)封(feng)(feng)，就必須(xu)對密(mi)封(feng)(feng)墊(dian)片(pian)施加足夠大的(de)(de)壓(ya)(ya)力(li)，使其發生彈(dan)性(xing)或(huo)塑(su)性(xing)變形以填充這些間隙。各(ge)種墊(dian)片(pian)材質(zhi)(zhi)的(de)(de)壓(ya)(ya)緊(jin)力(li)大小(xiao)通常(chang)在(zai)密(mi)封(feng)(feng)墊(dian)片(pian)生產(chan)廠家樣本或(huo)產(chan)品說明書(shu)中(zhong)給出，也可通過實驗決定。由(you)于(yu)裝配時達不(bu)(bu)到(dao)墊(dian)片(pian)所(suo)需的(de)(de)壓(ya)(ya)緊(jin)力(li)，或(huo)由(you)于(yu)在(zai)常(chang)期運行中(zhong)的(de)(de)振動使壓(ya)(ya)緊(jin)螺栓(shuan)松(song)動而使壓(ya)(ya)緊(jin)力(li)降低，以及由(you)于(yu)墊(dian)片(pian)材質(zhi)(zhi)的(de)(de)老化變形而喪失原(yuan)來(lai)的(de)(de)彈(dan)性(xing)，都(dou)會使墊(dian)片(pian)失效而產(chan)生泄漏(lou)。

3.化(hua)工泵墊(dian)(dian)(dian)片(pian)材質內(nei)部組織(zhi)或厚度不均勻，以(yi)及使(shi)用(yong)了(le)帶(dai)有(you)裂縫或折皺的(de)紙板。使(shi)墊(dian)(dian)(dian)片(pian)本身形成了(le)間隙，當作用(yong)在墊(dian)(dian)(dian)片(pian)上的(de)力使(shi)墊(dian)(dian)(dian)片(pian)所(suo)產生的(de)彈性(xing)變形不足以(yi)完(wan)全(quan)填充(chong)這些間隙時，化工(gong)泵泄漏也就不可避(bi)免了(le)。在化工(gong)泵的(de)墊(dian)(dian)(dian)圈選擇(ze)，安(an)裝，維護及保養的(de)過程中，都要加(jia)強(qiang)安(an)全(quan)生產意識，避(bi)免化工(gong)泵墊(dian)(dian)(dian)圈失(shi)效的(de)情況發生。
