BIA型结构是各类泵中最为常用的机械密封,属于内装内流型,传动形式橡胶波纹管通过紧固力带动旋转环同轴旋转,结构简单、紧凑。两套该型密封背对背安装,可以组成双端面结构的机械密封形式。

主要技术参数

密封介质:水,油等弱腐蚀性介质。
介质压力:0-1.0MPa
介质温度:-20-+100℃(丁晴橡胶) -20-+150℃(氟橡胶)
线速度: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.

Main technical parameters

Sealing medium: water, oil and other weak corrosive media.

Medium pressure: 0-1.0mpa

Medium temperature: - 20 - + 100 ℃ (NBR) - 20 - + 150 ℃ (fluororubber)

Linear speed: 10M / sec
