在英明领袖华主席“抓纲治国”的战略决策指引下,在五届人大的强劲东风鼓午下,我国国民经济蓬勃发展,科学技术突飞猛进。随之对国民经济大动脉——铁路运输的要求越来越高。为了满足需要,其中很重要的一面就是要不断提高铁路机车的质量。担负着铁路运输重任的新型牵引动力——电力机车和内燃机车——的质量还存在问题,特别是作为它们的驱功部件,地位重要的牵引电动机问题多、故障率高,与日新月异的发展形势不相适应。因此,如何提高牵引电机的制造水平及使用可靠性成了当务之急。为了能及时反映牵引电机的使用制造情况,交流先进经验和心得,我刊从本期开始增设“牵引电机通讯”栏。欢迎广大读者、各制造厂及机务段有关工人、技术人员踊跃投稿,各抒己见,为攻克牵引电机质量关而贡献力量。 Guided by the strategic decision of Chairman Hua, the wise leader, who has “grasped the guiding principle of governing the country,” under the strong east wind and drum spell of the Fifth National People’s Congress, our national economy is booming and science and technology are advancing by leaps and bounds. As a result, the requirements of the national economy, rail transport, have become higher and higher. In order to meet the needs, one of the most important aspects is to continually improve the quality of railway locomotives. The quality of the new traction power - electric locomotives and diesel locomotives - that bear the heavy responsibility of railway transportation still has some problems. Especially as their driving components, there are many problems of traction motors with important status, high failure rate and rapid development with each passing day Not suitable. Therefore, how to improve the manufacturing level and reliability of traction motors has become a top priority. In order to reflect the use of traction motor manufacturing situation in a timely manner, the exchange of advanced experience and experience, I published from the beginning of this issue “traction motor communication” column. Welcome readers, manufacturers and locomotive depot of the workers, technicians enthusiastic submission, express their views, in order to overcome the quality of traction motor to contribute.
