什么是機(jī)械密封？機(jī)械密封又稱(chēng)為端面密封，其至少有一對(duì)垂直于旋轉(zhuǎn)軸線的端面，該端面在流體壓力及補(bǔ)償機(jī)械外力（或磁力）的作用下，加之輔助密封的配合，與另一端面保持貼合并相對(duì)滑動(dòng)，從而防止流體泄漏。由于端面的緊密貼合，使密封端面之間形成微小間隙，當(dāng)有介質(zhì)通過(guò)此間隙時(shí)，形成極薄的液膜，造成阻力防止泄漏，并且潤(rùn)滑端面，獲取密封的效果。機(jī)械密封因其密封性能好，運(yùn)行穩(wěn)定、泄漏少，摩擦功耗低，使用周期長(zhǎng)，對(duì)軸磨損很小，并能滿足多種工況要求，因此被***應(yīng)用。它有那幾部分組成？（1）靜止環(huán)及旋轉(zhuǎn)環(huán)（動(dòng)環(huán)與靜環(huán)），通常為研磨面，又稱(chēng)為摩擦副。（2）以彈性元件為主的補(bǔ)充緩沖機(jī)構(gòu)。（3）輔助密封圈。（4）使動(dòng)環(huán)和軸一起旋轉(zhuǎn)的傳動(dòng)部件。機(jī)械密封在哪些設(shè)備常用？按設(shè)備可分為耐腐蝕泵、化工泵、氟塑料離心泵、反應(yīng)釜、離心機(jī)、風(fēng)機(jī)、潛水泵電機(jī)、冷凍機(jī)、內(nèi)燃機(jī)、冷卻水泵、耐酸堿泵等以及其它設(shè)備上使用，機(jī)械密封目前使用相當(dāng)廣。機(jī)械密封作用原理分類(lèi)：（1）密封端面的對(duì)數(shù)：?jiǎn)味嗣妫p端面，多端面。其中雙端面又分為軸向雙端面和徑向雙端面。（2）按照作用于密封端面流體壓力為卸載或不卸載可分為：非平衡式、部分平衡式、全平衡式。。哈爾濱神通博格曼機(jī)械密封112</p><p
