例如旋轉(zhuǎn)式和靜止式機(jī)械密封；內(nèi)流式和外流式機(jī)械密封；平衡型和非平衡型機(jī)械密封等。按補(bǔ)償機(jī)構(gòu)彈性元件的運(yùn)動(dòng)狀況，可分為旋轉(zhuǎn)式和靜止式機(jī)械密封。補(bǔ)償機(jī)構(gòu)隨軸旋轉(zhuǎn)的稱為旋轉(zhuǎn)式機(jī)械密封（圖2）；補(bǔ)償機(jī)構(gòu)不旋轉(zhuǎn)的（安裝在壓蓋內(nèi)）稱為靜止式機(jī)械密封（圖3）。補(bǔ)償機(jī)構(gòu)旋轉(zhuǎn)時(shí)易產(chǎn)生質(zhì)量不平衡，同時(shí)消耗攪拌功率，因此，旋轉(zhuǎn)式密封不能用于高速；而靜止式密封可用于高速。但是旋轉(zhuǎn)式密封安裝較方便，所以，普通的機(jī)械密封大多采用旋轉(zhuǎn)式結(jié)構(gòu)。按靜環(huán)的安裝位置可分為內(nèi)裝式和外裝式機(jī)械密封。靜環(huán)裝于密封壓蓋（或相當(dāng)于密封壓蓋的零件）內(nèi)側(cè)（即面向主機(jī)工作腔側(cè)）的機(jī)械密封稱為內(nèi)裝式機(jī)械密封（如圖1）；反之，在密封壓蓋的外側(cè)安裝靜環(huán)時(shí)稱為外裝式機(jī)械密封（圖4）。內(nèi)裝式機(jī)械密封可用于溫度和壓力較高，以及介質(zhì)對(duì)動(dòng)環(huán)及彈性元件的腐蝕性不高的工況。外裝式機(jī)械密封適用于低壓（或負(fù)壓）和介質(zhì)具有腐蝕性的工況。(圖4)密封流體在密封端面間的泄漏方向和離心力方向相反的機(jī)械密封稱為內(nèi)流型機(jī)械密封；密封流體在密封端面間的泄漏方向與離心力方向相同時(shí)稱為外流型機(jī)械密封。一般情況下，內(nèi)流型機(jī)械密封多出現(xiàn)在內(nèi)裝式機(jī)械密封中（如圖1、2、3）。德州2009釜用機(jī)械密封件。平頂山212釜用機(jī)械密封件選型</p><p
