BIA輕型機械密封是屬于內裝、內流型單端面結(jie)構(gou)，它(ta)的傳動(dong)(dong)形(xing)式(shi)是橡膠波紋(wen)管與(yu)軸通過緊(jin)固(gu)(gu)座的緊(jin)固(gu)(gu)力帶動(dong)(dong)動(dong)(dong)環同(tong)軸轉動(dong)(dong)。BIA輕型機械密封符合“DIN24960”標(biao)準，結(jie)構(gou)簡(jian)單、緊(jin)湊、可同(tong)“IS”泵配套。
BIA輕型機械(xie)密(mi)封適用(yong)范圍(wei)：
密封腔壓(ya)力：P≤0.8MPa
密封(feng)腔溫度：t=-20℃～80(150)℃
線速度：Vg≤10m/s
