因此在選用墊片材質(zhì)時應(yīng)查閱相關(guān)資料或通過實(shí)驗(yàn)后再做出正確選擇。三、化工泵填料密封化工泵填料密封是將富有壓縮性和回彈性的填料放入填料函內(nèi)，依靠壓蓋的軸向壓緊力轉(zhuǎn)化為徑向密封力，從而起到密封作用。這種密封方法稱為填料密封，這種填料稱為密封填料。由于填料密封結(jié)構(gòu)形式簡單，更換方便、價格低廉、適應(yīng)轉(zhuǎn)速、壓力、介質(zhì)寬泛而在化工泵的設(shè)計中得到普遍采用。填料密封的原理在機(jī)械行業(yè)中填料密封主要用作動密封，黑河凱泉泵用機(jī)械密封100YW120-18,常用作離心泵、壓縮機(jī)、真空泵、攪拌機(jī)的轉(zhuǎn)軸密封。填料裝入填料腔以后,經(jīng)壓蓋螺絲對它作軸向壓縮,當(dāng)軸與填料有相對運(yùn)動時,由于填料的塑性,使它產(chǎn)生徑向力,并與軸緊密接觸。與此同時,填料中浸漬的潤滑劑被擠出,在接觸面之間形成油膜。由于接觸狀態(tài)并不是特別均勻的,接觸部位便出現(xiàn)邊界潤滑狀態(tài)，黑河凱泉泵用機(jī)械密封100YW120-18,稱為”軸承效應(yīng)”;而未接觸的凹部形成小油槽,有較厚的油膜,接觸部位與非接觸部位組成一道不規(guī)則的迷宮,起阻止液流泄漏的作用,此稱”迷宮效應(yīng)”。這就是填料密封的機(jī)理。良好的密封在于維持“軸承效應(yīng)”和”迷宮效應(yīng)”，黑河凱泉泵用機(jī)械密封100YW120-18。也就是說,要保持良好的潤滑和適當(dāng)?shù)膲壕o，若潤滑不良,或壓得過緊都會使油膜中斷,造成填料與軸之間出現(xiàn)干摩擦,導(dǎo)致燒軸和出現(xiàn)嚴(yán)重磨損。因此。凱泉泵用機(jī)械密封65YW20-9。黑河凱泉泵用機(jī)械密封100YW120-18</p><div

而螺紋只起提供壓緊力的作用。螺紋密封在化工泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟(jì)密封，二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外，密封面的粗糙度以及與螺紋孔的相對幾何位置精度對密封效果影響也很大。于由密封墊片在擰緊螺紋時不僅承受壓緊力，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當(dāng)墊片為非金屬時，一般只適用于壓力不高的化工泵，如果墊片為金屬則適用壓力可達(dá)30Mpa以上?；け蒙辖?jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟(jì)性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無論采用“錐對錐”還是“柱對錐”，密封效果相同，只是使用地域不同而已。七、化工泵迷宮密封在設(shè)計合理，加工精良，裝配完好、轉(zhuǎn)速較高時，迷宮密封效果很好。但在實(shí)際應(yīng)用中，因此而產(chǎn)生的化工泵泄漏卻很多，所以在化工泵密封中不常用。在設(shè)計合理，加工精良，裝配完好、轉(zhuǎn)速較高時。黑河凱泉泵用機(jī)械密封100YW120-18凱泉泵用機(jī)械密封MD48-50。</p><div
