感觉有颗粒,用机械密封也只是权宜之计。我单位有两台催化剂进料泵,含有 0.5%的固体颗粒,一个季度左右就会内漏,介质侧的动静环处的死区累积固体颗粒,造成介质侧失去补偿(P-3A)

市场上的机械隔膜泵最高能承受1-1公斤压力,但这是极限还得是进口的;液压隔膜泵可以达到

其实我的第一反应也是实用气力输送方式!:$

市场上的机械隔膜泵最高12公斤压力,但这是极限还得是进口的;液压隔膜泵可以去到0-170公斤,可以兼容细小颗粒,因为有橡胶塑料啥的温度建议80℃以下,最高110℃。液压隔膜泵就是比较贵。

颗粒物大选择单螺杆给料,颗粒物小选择双螺杆给料,然后气体输送;如果距离较短,没有弯头,给料部位无压力,可以采用螺旋给料机直接添加
