填料密封虽然是一种古老而简单的轴封结构,但由于具有适应范围广泛、结构简单、安装维修方便、价格低廉等优点,迄今为止,仍然是一种不可缺少的密封型式。从泵、阀门、压缩机、风机、分离机等通用机械产品来看,用作密封填料的种类有石棉、橡胶、工程塑料、碳石墨、碳纤维等密封材料制品。由于这些密封制品使用前缺乏合理和完整的科学分析,因而工矿企业中的一些机器和设备出现跑、冒、滴漏现象甚多。实践证明,解决好填料密封问题,对安全生产和节约能源有着重要的意义。为了提高通用机械产品的填料密封效果,我所设计加下了填料密封性能试验机,并进行
Although the packing seal is an ancient and simple shaft seal structure, it is still an indispensable seal type due to its advantages of wide adaptability, simple structure, easy installation and maintenance, low price and so on. From pumps, valves, compressors, fans, separators and other general machinery products, used as a variety of sealing filler asbestos, rubber, engineering plastics, carbon graphite, carbon fiber and other sealing material products. Due to the lack of reasonable and complete scientific analysis of these sealed products before use, some machinery and equipment in the industrial and mining enterprises are running, running and dripping. Practice has proved that to solve the problem of packing seal, safety and energy conservation is of great significance. In order to improve packing sealing effect of general mechanical products, I designed to add filler sealing performance testing machine, and
