關于(yu)攪(jiao)拌器(qi)(qi)(qi)結構的密封問(wen)題       攪(jiao)拌器(qi)(qi)(qi)適用(yong)(yong)(yong)于(yu)石油鉆井液的攪(jiao)拌，結構緊(jin)湊、占地面積(ji)小;7.5kw以上鉆井液攪(jiao)拌器(qi)(qi)(qi)采用(yong)(yong)(yong)蝸輪蝸桿式減速傳動，具有傳遞(di)扭矩大、運(yun)轉平穩、工作(zuo)可靠等優(you)點。常用(yong)(yong)(yong)鉆井液攪(jiao)拌器(qi)(qi)(qi)型(xing)號為J320，J140，J360和(he)J310。為保障攪(jiao)拌器(qi)(qi)(qi)的工作(zuo)性(xing)能(neng)，其密封性(xing)問(wen)題是廣大用(yong)(yong)(yong)戶(hu)所關注的，下(xia)面技術(shu)部做以下(xia)概述：

攪拌(ban)器可靠的(de)密(mi)封是一個重要(yao)的(de)問(wen)題(ti)。由于攪拌(ban)軸(zhou)密(mi)封引起(qi)的(de)漏油(you)(you)，不但大量浪費油(you)(you)料(liao)，而且(qie)污(wu)染了鉆井液。旋轉軸(zhou)密(mi)封分(fen)為(wei)機械密(mi)封和填料(liao)密(mi)封，鉆井液攪拌(ban)器的(de)軸(zhou)屬于低轉速、低壓力，較適用的(de)仍是填料(liao)密(mi)封，因(yin)為(wei)它具(ju)有結構簡(jian)單，常德攪拌(ban)器，易于維修，可靠性高等優點。

填(tian)(tian)料(liao)(liao)密封是一(yi)種(zhong)早期轉軸密封結構(gou)，由于(yu)(yu)結構(gou)簡單，在攪拌(ban)(ban)器中(zhong)時(shi)有采用(yong)。填(tian)(tian)料(liao)(liao)密封的(de)原理是靠壓蓋(gai)壓力作(zuo)用(yong)下，壓緊填(tian)(tian)料(liao)(liao)密封盒中(zhong)的(de)填(tian)(tian)料(liao)(liao)，對攪拌(ban)(ban)軸表面產生徑向(xiang)壓力。由于(yu)(yu)填(tian)(tian)料(liao)(liao)中(zhong)含(han)有潤滑劑，因(yin)此在攪拌(ban)(ban)軸上(shang)產生一(yi)層液膜，它(ta)既潤滑了攪拌(ban)(ban)軸，又(you)能阻止設備中(zhong)的(de)潤滑油漏出(chu)來。

希望上面給大家介紹(shao)的(de)攪(jiao)拌器(qi)結(jie)構(gou)的(de)密封問題，可(ke)以給大家帶來幫助。

攪拌(ban)器(qi)的轉(zhuan)向，從外面看絕大多數是(shi)順指針(zhen)轉(zhuan)向，但也不一定，主要看葉(xie)(xie)片安裝情況。葉(xie)(xie)片旋轉(zhuan)過程(cheng)，攪拌(ban)器(qi)將槳葉(xie)(xie)向斜下方(fang)推動漿液，依此判定攪拌(ban)器(qi)旋轉(zhuan)方(fang)向。

依(yi)賴經驗(yan)和實驗(yan)，放大較難  兩(liang)個(ge)規模(mo)不(bu)同(tong)但幾何相似的攪(jiao)(jiao)拌(ban)(ban)(ban)器(qi)(qi)，假使(shi)兩(liang)釜(fu)內(nei)流(liu)體(ti)相同(tong)，大器(qi)(qi)中很(hen)難獲得(de)(de)和小(xiao)器(qi)(qi)中同(tong)樣的流(liu)速分布(bu)。而(er)且對(dui)許多攪(jiao)(jiao)拌(ban)(ban)(ban)操作，達(da)到同(tong)樣的攪(jiao)(jiao)拌(ban)(ban)(ban)效果，大器(qi)(qi)中單位(wei)質量流(liu)體(ti)所輸入的能量與小(xiao)器(qi)(qi)相比可能會有很(hen)大的差(cha)別。這就(jiu)使(shi)大攪(jiao)(jiao)拌(ban)(ban)(ban)器(qi)(qi)中要重(zhong)現小(xiao)器(qi)(qi)中的過程(cheng)結果，即攪(jiao)(jiao)拌(ban)(ban)(ban)釜(fu)的放大，變得(de)(de)困難。至今對(dui)于復(fu)雜過程(cheng)得(de)(de)放大，仍無(wu)法用理論預測，必須進行大量得(de)(de)實驗(yan)研究(jiu)。有時，為(wei)了使(shi)攪(jiao)(jiao)拌(ban)(ban)(ban)器(qi)(qi)大型(xing)化，不(bu)得(de)(de)不(bu)在大型(xing)得(de)(de)實驗(yan)器(qi)(qi)中進行試(shi)驗(yan)，大型(xing)實驗(yan)釜(fu)得(de)(de)容積(ji)甚至達(da)到2000m3以上.因而(er)可以說，攪(jiao)(jiao)拌(ban)(ban)(ban)技術至今還是對(dui)經驗(yan)和實驗(yan)依(yi)賴性很(hen)大得(de)(de)工(gong)程(cheng)技術。

另一方(fang)面，同一攪拌(ban)操作可用多種不(bu)同結構(gou)得攪拌(ban)器來(lai)完成，但不(bu)同得實施方(fang)案所(suo)需得能耗和(he)器投(tou)資是(shi)不(bu)同的，有時會有成倍的差別。
