应用钢背聚甲醛材料做水轮机导叶轴套和连杆肖轴套。哈尔滨大电机研究所在新设计的试验装置上进行了耐磨试验。在保持轴承上5000Kgf恒定力作用下,左右摆动2万5千次,测量结果摩擦系数小、磨损量低。推算真机使用寿命可达20年以上。现已用于张滩、官厅、太平湾、红石等机组上。试用证明,这种材料的轴套具有尺寸稳定、结构简单、寿命长、价格便宜、自润滑性好,可省去供油设备等特点,是目前理想的材料.优于国外一些厂家常用的材料。
Application of steel back polyacetal material to do turbine bushings and connecting rod Shaft sleeve. Harbin Institute of Electrical Engineers in the newly designed test device wear test. Under the constant force of 5000Kgf on the bearing, it swings about 25,000 times, the friction coefficient is small and the wear amount is low. Projection of real life of up to 20 years. Is now used for Zhang Beach, Guanting, Taiping Bay, Hongshi and other units. Proof of trial, the material of the sleeve with a dimensional stability, simple structure, long life, low cost, good self-lubricating, oil-saving equipment can be omitted, etc., is the ideal material. Superior to some foreign manufacturers of commonly used materials .
