在伟大领袖毛主席“独立自主、自力更生”、“备战、备荒、为人民”的伟大战略方针指引下,为了加速铁路牵引动力革命,赶超世界先进水平,把人民铁路交通事业建设得更好,当前我厂正在试制采用液力传动装置的大功率内燃机车.液力变扭器的涡轮、泵轮和导向轮等叶轮是液力传动装置中的重要部件.一般中、小功率的液力变扭器的叶轮部件都采用铆接结构,在高速、大功率的工况下,如仍采用铆接结构,不仅会因铆钉的松动影响传动效率,甚至会由此造成破坏事故.因此,必须将铆接结构改为焊接结构,即将铆接工艺改成钎焊工艺. 遵照毛主席关于“工人阶级必须领导一切”
Guided by the great strategic principle of “independence, self-reliance, preparation for shortage and for the people” of Chairman Mao, the great leader, in order to speed up the power-rail revolution and catch up with and surpass the advanced world level and build a better transportation business for People’s Railway, Our factory is trying out the high-power diesel locomotive with hydraulic transmission.It is an important part of the hydraulic transmission device that impellers, such as turbine, impeller and guide wheel of the torque converter, etc. Generally, the low-power hydraulic torque In the high-speed, high-power operating conditions, such as the use of riveted structure, not only because of loose rivets affect the transmission efficiency, or even cause damage. Therefore, the riveting structure must be changed For the welding structure, the riveting process will be changed to brazing process.Comply with Chairman Mao on “the working class must lead everything”
