常見密封按照密封面是否存在相對(duì)運(yùn)動(dòng)分為靜密封與動(dòng)密封，動(dòng)密封又包括往復(fù)直線運(yùn)動(dòng)和旋轉(zhuǎn)軸密封，本例是旋轉(zhuǎn)軸密封。一般的軸封比較常見的有機(jī)械密封、填料（又稱盤根）、油封、螺旋密封、浮動(dòng)碳環(huán)密封、磁流體密封、干氣密封、刷式密封等。碳環(huán)密封、干氣密封、刷式密封通常用于密封氣體；機(jī)械密封、填料、油封一般用于密封液體。按照本例來(lái)說(shuō)，流體應(yīng)該是液體，假定壓力和轉(zhuǎn)速均較高，可以排除油封（用于輕載工況）；剩下的選擇有2種：機(jī)械密封或者填料密封。推薦選用機(jī)械密封，原因如下：同填料密封相比，它具有如下優(yōu)勢(shì)：密封性好，泄漏量比填料低一個(gè)數(shù)量級(jí)；使用壽命長(zhǎng)；不需要經(jīng)常調(diào)整，內(nèi)蒙古機(jī)械密封件組成，磨損后自動(dòng)補(bǔ)償；摩擦功率小，一般*為填料密封的；軸或軸套不產(chǎn)生磨損；耐震性強(qiáng)，當(dāng)設(shè)備在一定范圍內(nèi)振動(dòng)時(shí)，內(nèi)蒙古機(jī)械密封件組成，仍能保持良好密封效果。附上圖片，這個(gè)是機(jī)械密封完整的機(jī)械密封如上面的圖紙所示：它構(gòu)造了一個(gè)由旋轉(zhuǎn)軸驅(qū)動(dòng)的旋轉(zhuǎn)組件和與靜止殼體做成一體的靜止組件，二者接觸表面垂直于軸線方向，內(nèi)蒙古機(jī)械密封件組成。通過(guò)施加合適的力(彈簧和液體壓力)形成一個(gè)阻止介質(zhì)泄漏的密封面，并且在彈簧的作用下磨損后自動(dòng)補(bǔ)償。包括但不限于:靜密封，動(dòng)密封，非平衡式密封，平衡式密封，摩擦副，海水冷卻。高新區(qū)109-20機(jī)械密封件。內(nèi)蒙古機(jī)械密封件組成</p><div
