BIA型結(jié)構(gòu)是各類泵中最為常用的機(jī)械密封，屬于內(nèi)裝內(nèi)流型，傳動形式橡膠波紋管通過緊固力帶動旋轉(zhuǎn)環(huán)同軸旋轉(zhuǎn)，結(jié)構(gòu)簡單、緊湊。兩套該型密封背對背安裝，可以組成雙端面結(jié)構(gòu)的機(jī)械密封形式。

主要技術(shù)參數(shù)

密封介質(zhì)：水，油等弱腐蝕性介質(zhì)。
介質(zhì)壓力：0－1.0MPa
介質(zhì)溫度：-20－+100℃(丁晴橡膠） -20－+150℃(氟橡膠）
線速度：10m/sec

BIA structure is the most commonly used mechanical seal in all kinds of pumps. It belongs to internal flow type and transmission type. Rubber bellows drive the rotating ring to rotate in the same axis by tightening force. The structure is simple and compact. Two sets of this type of seal are installed back to back, which can form a mechanical seal with double end face structure.
