去年,我厂采用柔性石墨取代浸油棉纱、橡胶盘根、石棉盘根作为泵类动密封的填料,取得了比较满意的结果。一些油泵、酸泵、碱泵的密封状况得到改善,泄漏量大大减少。它比之一般盘根密封以及机械密封,密封效果显著提高,维护检修更为方便,使用寿命长,经济上合算。总的来说,柔性石墨在泵类动密封上的应用基本上是成功的。下面把我们的应用情况作一介绍。 Last year, our factory replaced the oil-impregnated cotton yarn with flexible graphite, and the rubber packing and asbestos packing were used as packing for dynamic seals of pumps. Satisfactory results were achieved. Some pumps, acid pumps, alkali pump seal conditions have been improved, greatly reducing the amount of leakage. It than the general packing and mechanical seal, seal significantly improved, more convenient maintenance and overhaul, long life, cost-effective. In general, the application of flexible graphite in the pump dynamic sealing is basically successful. Here’s an introduction to our application.
