密封面的粗糙度以及與螺紋孔的相對(duì)幾何位置精度對(duì)密封效果影響也很大。于由密封墊片在擰緊螺紋時(shí)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(shí)，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(duì)錐”還是“柱對(duì)錐”，密封效果相同，只是使用地域不同而已。5、迷宮密封在設(shè)計(jì)合理，加工精良，裝配完好、轉(zhuǎn)速較高時(shí)，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(jì)合理，加工精良，裝配完好、轉(zhuǎn)速較高時(shí)，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，分析其原因主要有：密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車刀痕在有些情況下也加大了化工泵泄漏趨勢。滄州安德里茲泵用機(jī)械密封SAF-55-QREG-304449哈爾濱11-LP-D-S32-D20/60-DE安德里茲泵用機(jī)械密封。</p><div

比YG6大1倍多，為／℃（10～500℃時(shí)）。這兩點(diǎn)決定了耐熱沖擊性能不如YG6好。正因?yàn)榫€膨脹系數(shù)較大，和馬氏體不銹鋼接近（10～500℃時(shí)為11X10-6／℃），為和環(huán)座焊接提供了有利條件。焊接時(shí)需在環(huán)和座之間鋪放一層鎳基粉末，置于真空電阻爐中，經(jīng)1100℃高溫熔焊，然后進(jìn)行回火處理，以消除焊接應(yīng)力。由于是焊接的密封環(huán)，硬質(zhì)合金環(huán)的厚度可以比YG6薄，毛坯的厚度也只有3～3．5mm。以因密度小，是YG6的一半（7~），因此，可節(jié)約貴重金屬，價(jià)格較低。這種合金的牌號(hào)為CN15，其中Cr3C285%，Ni為15%，由北京硬質(zhì)合金廠研制成功。熱裝式密封環(huán)以其性能***應(yīng)用，但過盈量過大則硬質(zhì)合金在較大擠壓應(yīng)力作用下產(chǎn)生變形；過盈量過小，使用時(shí)會(huì)松脫。經(jīng)長期觀察分析，熱裝式密封環(huán)松脫主要是由于環(huán)座和硬質(zhì)合金環(huán)兩者線膨脹純利系數(shù)的差別，工作出現(xiàn)間隙。由此可見，熱裝式密封環(huán)失效的根本原因主要有二：一是過盈值小，三是環(huán)座材料選擇不當(dāng)，線膨脹系數(shù)太大。確定過盈值應(yīng)遵循的原則：1）從傳遞扭矩的角度考慮過盈值應(yīng)足夠大。2）從環(huán)的變形的角度考慮過盈值不可過大。綜合起來，在滿足環(huán)和座傳遞扭矩的情況下，取小的過盈值。順義區(qū)安德里茲泵用機(jī)械密封JCS2A-70-QREQ</p><p
