橡胶密封圈的寿命,直接影响到液压、气压系统的质量。延长密封圈寿命,有许多方法。除了提高密封圈本身的质量以外,还可以从其他因素去考虑。许多生产厂家,在生产液压缸时,往往在活塞杆上镀铬,以提高活塞表面的质量。但工艺复杂、成本高。现在,美国一家化工产品公司,生产了一种热固型干膜润滑剂,可以代替活塞杆的镀铬工艺。
The life of the rubber seal directly affects the quality of the hydraulic and pneumatic systems. There are many ways to extend the life of the seal. In addition to improving the quality of the seal itself, other factors can be considered. Many manufacturers, in the production of hydraulic cylinders, often chrome on the piston rod to improve the quality of the piston surface. But the process is complicated and the cost is high. Now, a chemical company in the United States has produced a thermosetting dry film lubricant that can replace the piston rod chrome plating process.
