填料的安装1.填料是阻止气缸的气体不从活塞杆处泄漏的组件,对填料的基本要求是密封性能良好并耐用。目前,填料密封元件的结构形式有锥面、平面等。梯形截面锥面密封元件用于中、高压填料;平面的又有二瓣和四瓣、三瓣和三瓣、三瓣和六瓣之分,平面密封元件用于中、低压填料。填料密封元件的材料为铸铁、黄铜、巴氏合金、工程塑料（填充聚四氟乙烯、尼龙）等。2.填料密封元件应与活塞杆进行配研。配研时应使用刮刀刮研,严禁使用金刚砂研磨。因为一般填料的材质密度疏松,金刚砂进
Packing Installation 1. Packing is to prevent the gas cylinder does not leak from the piston rod assembly, the basic requirements for the packing is good sealing performance and durability. At present, the packing seal structure of the form of a cone, plane and so on. Trapezoidal cross-section tapered sealing element for medium and high pressure packing; plane and two and four, three and three, three and six, the flat sealing element for medium and low pressure packing. The material of the packing seal element is cast iron, brass, babbitt, engineering plastic (filled with polytetrafluoroethylene, nylon) and the like. 2. Packing sealing element should be with the piston rod with research. With the research should be used to scratch scraping, non-use of emery grinding. Because of the general packing material density loose, corundum into
