  墊片密封、填料密封、金臺機械密封、非接觸(chu)型(xing)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)以及注(zhu)劑式(shi)帶壓堵(du)漏是(shi)常(chang)見的(de)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)形式(shi)。其中填(tian)料密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)應該(gai)算是(shi)常(chang)見的(de),成型(xing)填(tian)料密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)包括我(wo)們常(chang)見的(de)O形圈、Y形圈、油封(feng)(feng)(feng)(feng)(feng)(feng)等等。非接觸(chu)型(xing)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)包括間隙密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)、迷宮密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)、浮動(dong)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)、動(dong)力密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)、磁流體密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)和全封(feng)(feng)(feng)(feng)(feng)(feng)閉(bi)式(shi)密(mi)(mi)(mi)封(feng)(feng)(feng)(feng)(feng)(feng)。


  渣漿金臺泵用金臺機械密封還包括軟填(tian)(tian)料(liao)密封(feng)(feng)(feng)(feng)(feng)、硬填(tian)(tian)料(liao)密封(feng)(feng)(feng)(feng)(feng)和成型填(tian)(tian)料(liao)密封(feng)(feng)(feng)(feng)(feng)。隨著高(gao)分子(zi)有機合成工業的迅猛(meng)發(fa)展,出(chu)現(xian)了液態密封(feng)(feng)(feng)(feng)(feng)膠,使用(yong)于(yu)靜密封(feng)(feng)(feng)(feng)(feng);這(zhe)項新技術(shu),通常(chang)叫(jiao)做液體密封(feng)(feng)(feng)(feng)(feng)。是(shi)利用(yong)液態密封(feng)(feng)(feng)(feng)(feng)膠的粘附(fu)性(xing)、流動(dong)性(xing)和單分子(zi)膜效應,在(zai)適當壓力下,使它象(xiang)墊(dian)圈一樣(yang)地起作用(yong)。

  在裝配金臺機械密封時,軸的軸向竄動量應小于0.1毫米,輔助密封與軸的過盈量適中,在保證徑向密封的同時,動環裝配后保證能在軸上靈活移動(把動環壓向彈簧能自由彈回來),由于彈簧比壓力及總比壓設計過大,密封腔內的壓力超過3Mpa時,會使密封端面比壓過大,液膜難以形成,密封端面磨損嚴重,發熱量增多,造成密封面熱變形。保證下端蓋、油室的清潔度,對不清潔的潤滑油禁止裝配;渣漿金臺泵用金臺機械密封內油面線應高于密封面;根據不同介質選用不同結構的金臺機械密封,如對腐蝕性介質,橡膠件應選用耐高溫、耐弱酸、弱堿的氟橡膠,在固體顆粒容易進入的位置選用碳化鎢對碳化鎢摩擦副的金臺機械密封
