玉环县密封器材厂在浙江省机电设计研究院的帮助下,试制成功新颖的泵用密封材料——复合材料石墨成型密封圈,为我国泵类行业增加了一种性能优异的密封新材料,已列入机电部“八五泵类节能规划”。最近,在杭州通过签定。以往,我国的水泵密封件,主要采用石棉盘根,它不但摩擦系数大、耗能高、易磨损、泄漏严重、维修费用高,且因石棉含有强烈的致癌物质,最近已被许多发达国家明文禁用。而国内现有的柔性石墨密封材料,也存在着易破碎、价格高、密封性能欠佳等缺陷。
Yuhuan County Seal Equipment Factory in Zhejiang Province, with the help of Mechanical and Electrical Design Institute, trial success of the new pump seal material - composite graphite molding ring, the pump industry in our country has added a new sealing material with excellent performance, has Included in the Electrical and Mechanical Services Department, “85 pump energy-saving plan.” Recently, signed in Hangzhou. In the past, our country’s pump seals, the main use of asbestos packing, which not only the friction coefficient, high energy consumption, easy to wear and tear, serious leakage, high maintenance costs, and because of asbestos contains a strong carcinogen, has recently been developed in many countries Disabled The existing domestic flexible graphite sealing materials, there are also fragile, high prices, poor sealing performance and other defects.
