填料又叫盤根，它是一種石墨或黃油浸透的棉織物及石棉，有的是金屬箔包石棉芯子等。密封的嚴(yán)密性可用松緊填料壓蓋的方法來調(diào)節(jié)。機(jī)械密封又叫端面密封，如圖1-19所示。機(jī)械密封主要靠靜環(huán)和動(dòng)環(huán)的端面摩擦來密封。機(jī)械密封比填料密封的密封性好，泄漏少，壽命長(zhǎng)，功率消耗小。但機(jī)械密封制造較復(fù)雜，精度要求高，價(jià)格貴，同時(shí)安裝技術(shù)要求也較高。浮動(dòng)環(huán)密封是借助浮動(dòng)環(huán)端面、浮動(dòng)套(支承環(huán))端面在液體壓力和彈簧力(有的不用彈簧)的作用下，使液體得到徑向密封(圖1-2)。
