对水介质采用磁流体密封,一直为人们所关注。我们对氨水泵磁流体密封进行了试验研究,获得满意的效果。在试验研究中推导出静密封压差的计算公式,为密封间隙的结构设计提供了依据。
The use of magnetic fluid seals on water media has been of concern. We conducted a pilot study of ammonia pump magnetic fluid seal to obtain satisfactory results. In the experimental study, the calculation formula of static seal pressure difference is derived, which provides the basis for the structural design of seal clearance.
