不停车带压密封是20世纪70年代发展起来的先进的设备维修技术,它不用停车无需动火就能消除泄漏,操作简便、安全、迅速、可靠,可广泛应用于石油、化工、冶金、电力、航运等行业,特别是对涉及易燃易爆、有毒有害及有腐蚀性物质的石油化工生产有着重要意义。不停车带压密封技术原理以流体介质在动态情况下建立密封结构,即介质处于有温度有压力和流动状态下建立起密封结构,从而消除泄漏。特点①在堵漏过程中不需要停车、不 Non-stop pressure seal is an advanced equipment maintenance technology developed in the 1970s. It can eliminate leakage without stopping the fire and is easy to operate, safe, rapid and reliable. It can be widely used in petroleum, chemical, metallurgy and electric power , Shipping and other industries, especially for the petrochemical production involving flammable, explosive, poisonous, harmful and corrosive substances. Non-stop pressure seal technology with the principle of fluid medium to establish a sealed structure under dynamic conditions, the media in a temperature and pressure and flow under the established seal structure, thus eliminating leakage. Features ① in the plugging process does not require parking, no
