时代在发展,社会在进步。中国的高铁技术逐渐成为世界领先的铁路建设运输技术,极大保障了快速运行铁路的安全性和经济性。随着人们对于交通便利性需求的急剧上升,我国进入21世纪后,结合高铁技术的突破,迅速在我国大力发展高铁。高速铁路的发展,对于道岔的施工质量要求越来越高。ZYJ型液压转辙机作为铁路外锁闭道岔的主要实现设备,如何利用与设备工艺的完善成为中铁研发的主要课题之一。为了有效降低闭道岔铺设成本,需要延长ZYJ7型电液压转辙机的使用寿命。因此,及时维护保养意义重大。 Times are developing and society is progressing. China’s high-speed rail technology has gradually become the world’s leading railway construction and transportation technology, which has greatly ensured the safety and economy of the rapidly operating railways. With the rapid rise of people’s demand for transportation convenience, China’s entry into the 21st century, combined with the breakthrough of high-speed railway technology, will rapidly develop high-speed rail in our country. The development of high-speed railway has become increasingly demanding for the construction quality of turnouts. ZYJ hydraulic switch machine as the main realization of the railway locking switch turnout, how to use and improve the equipment technology has become one of the main research and development of China Railway. In order to effectively reduce the cost of turnout turnout, you need to extend the service life of ZYJ7 type electro-hydraulic switch machine. Therefore, timely maintenance is of great significance.
