Maybe next year, when you take the railway bus with a speed of more than 140 kilometers per hour, the passenger car uses the bearings made by Luoyang.
During the Mid-Autumn Festival holiday, Henan Energy Luoyang LYC Bearing Co., Ltd. was a busy scene. This old state-owned enterprise is concentrating on the company's efforts to tighten the first-class technical requirements, 160 km/h technical requirements and precision reserves, and carefully produce the first batch of railway passenger car bearing samples with a speed of more than 140 km/h. This move marks the first step in the localization of high-speed railway passenger car bearings, and it also means that the history of railway passenger cars with a speed of more than 140 kilometers per hour will be rewritten.
On August 14, China Railway Corporation held a test review meeting for the use of NJ(P)3226X1 domestic bearings for 25K passenger cars in Beijing. The participating experts listened to the research and development of domestic bearings, bench test and installation, as well as the difference between imported bearings and raw materials in major raw materials and main production processes. The participating experts agreed that the conditions for speeding up the use of domestically produced bearings have matured, and it is officially clarified that the 25K-type passenger car will be equipped with the domestically produced NJ(P)3226X1 bearing produced by Luozhou and other enterprises.
At this point, the Chinese railway industry officially opened the curtain of the localization of railway passenger car bearings with a speed of more than 140 kilometers per hour. It is understood that if the application test is successful, the next step will be to gradually test the speed of 160 km, 200 km, 250 km and 350 km per hour.
Anyone familiar with the history of domestic railway passenger car bearings knows that this is a major stage of progress in domestic bearings and is a milestone. For a long time, because of the high risk and great impact of high-speed railway passenger car bearings, the host users have insufficient confidence in the selection of domestic bearings. In order to avoid risks, some users only purchase imported bearings, setting thresholds for domestic bearing access, and limiting the development of domestic high-end bearings such as high-speed rail bearings.
"We have waited for 9 years on this day, it is not easy. We will seize this opportunity to completely change the embarrassing situation of railway passenger cars with a speed of 140 kilometers or more without using domestic bearings." Yesterday, Luozhou Railway Bearing Division Technology The person in charge said excitedly.
As the backbone enterprise of the equipment manufacturing section of Henan Energy and Chemical Industry Group, Luo axis is the most comprehensive unit of domestic railway bearing production. After years of efforts, it has been able to mass produce bearings for railway wagons, buses, locomotives, subways and light rails. Since 2006, Luozhou has successively developed and produced the first batch of railway passenger car bearings with speeds of 140 km, 160 km, 200 km, 250 km and 350 km, and passed the bench test of the national authority.
A few days ago, Luozhou was responsible for the "863" project, the key project of the advanced manufacturing technology field, "Development of large-scale special bearing test bench" - "large-scale high-speed railway bearing test bench" successfully passed the on-site inspection and acceptance of the Ministry of Science and Technology. The successful development of the test bench can provide test data for the independent development of high-speed railway bearings in China, laying a foundation for the localization of high-speed rail bearings.
With this Dongfeng, Luozhou quickly started the localization replacement project of railway passenger cars with a speed of more than 140 kilometers per hour. The work of the railway bearing division has been fully rolled out. They are determined to implement lean management and continuously promote technological innovation to ensure the first batch of high-speed rail samples. The bearing passed the user road test smoothly.
It is reported that at present, there are more than 1 million sets of various types of LYC brand bearings working on the major railway lines across the country, ensuring the safe operation of trains from south to north.
