随着我国工业的飞跃发展,很多具有优良综合性能的工程塑料被大量应用于国民经济的各个部门。遵照毛主席关于“我们必须打破常规,尽量采用先进技术”的伟大教导,我们在哈尔滨大电机研究所的帮助下,使用聚甲醛材料制作导水叶轴套,用以代替磷青铜合金材料,在一号、二号、四号水轮机上,运行时间最长的已经两年多。我们多次在机组小修时对聚甲
With the rapid development of our country’s industry, many engineering plastics with excellent overall performance have been widely used in various sectors of the national economy. In accordance with Chairman Mao’s great teaching on “We must break the routine and try our best to adopt advanced technology”, we use the help of Harbin Institute of Electrical Engineers to make the water guide vane sleeve made of POM to replace the phosphor bronze alloy material. One, two, four on the turbine, the longest running time has more than two years. We repeatedly in the crew when the repair of Poly Jia
