螺桿泵機械密封技術(shù)要求：
密封環(huán)是動環(huán)和靜環(huán)的總稱(下同)，是構(gòu)成機械密封最主要的元件。密封環(huán)在很大程度上決定了機械密封的使用性能和壽命，因此，對它提出了一些要求。
1、有足夠的強度和剛度
在工作條件下(如壓力、溫度和滑動速度等)不損壞，變形應(yīng)盡量的小，工作條件波動時仍能保持密封性。尤其是密封端面要有足夠的強度以及一定的耐腐蝕能力，以保證產(chǎn)品有滿意的使用壽命。
2、有良好的耐熱沖擊能力
為此，要求材料有較高的導(dǎo)熱系數(shù)和較小的線膨脹系數(shù)，承受熱沖擊時不至于開裂。
3、較小的摩擦系數(shù)
密封環(huán)匹配應(yīng)有較小的摩擦系數(shù)。
4、良好的自潤滑性
工作中如發(fā)生短時間的干摩擦，不損傷密封端面。因此，密封環(huán)要有良好的自潤滑性，密封環(huán)材料與密封流體還要有很好的浸潤性。
5、結(jié)構(gòu)簡單
密封環(huán)結(jié)構(gòu)應(yīng)力求簡單對稱，優(yōu)先考慮用整體型結(jié)構(gòu)，也可采用組合式(如鑲裝式)密封環(huán)，盡量避免用密封端面噴涂式結(jié)構(gòu)。
6、密封環(huán)要容易加工制造
安裝和維修要方便，價格要低廉。
