供水厂是集团公司水处理专业厂,2000年前的水泵密封基本采用的是软填料密封,运行和维修人员的维护量较大,经常发生由于运行维护不当导致水泵不上水,影响及时供水的现象,且由于填料密封摩擦较大,引起耗能。随着密封技术的发展,我们通过对机械密封和软填料密封的分析比较,在2002～2010年6年间,在3号、4号、新1号高炉异地大修和4号、5号、6号、7号转炉供水系统的净环供水机组的水泵(共计85台)全部采用了机械密封装置,通过近6年的实际运行,解决了水泵密封困扰安全运行问题,极大地减轻了运行和维修人员的劳动强度,达到了节能的目的。
The water supply plant is a professional water treatment plant of the group company. Before 2000, the pump seal basically adopted the soft packing seal, and the operation and maintenance personnel had a large amount of maintenance. It often happened that the pump could not be put on the water because of the improper operation and maintenance, which affected the timely water supply Phenomenon, and due to packing seal friction, causing energy consumption. With the development of sealing technology, we analyzed and compared the mechanical seal and the soft packing seal. During the 6 years from 2002 to 2010, the No. 3, No. 4 and No. 1 blast furnaces were overhauled and the No. 4, No. 5 and No. 6 , The No. 7 converter water supply system of the net ring water supply units of the pump (a total of 85 units) all the mechanical seal, through the actual operation of nearly 6 years to solve the pump seal troubles safety operation, greatly reducing the operation and maintenance personnel The labor intensity, reached the purpose of energy conservation.
