机械密封是一种动力机械和流体机械中非常重要的零件,它又称之为端面密封。机械密封可以对化工企业中的流体具有非常好的密封效果。本文首先对化工机泵机械密封的机构形式进行了探析,然后就如何应用泵用机封材料和选择泵用机封材料进行了探讨,旨在与同行交流提高机械密封技术在化工机泵中的应用水平。 Mechanical seal is a kind of power machinery and fluid machinery is a very important part, it is also known as the end seal. Mechanical seals have a very good sealing effect on the fluids in the chemical industry. In this paper, the chemical mechanical pump mechanical seal form of the body were explored, and then on how to use the pump machine seal material and select the pump machine seal material was discussed, with the exchange to improve the mechanical seal technology in the chemical pump Application level.
