油压减振器是机车、客车的重要部件，国产油压减振器在长期运行中暴露出漏油和连接头损坏等质量与性能不稳定的问题，尤其提速后国产油压减振器问题更多，无法满足提速的要求，需要从国外进口。为了早日实现油压减振器国产化，替代进口产品，提高我国机车车辆制造水平，戚墅堰
Hydraulic shock absorber is an important part of locomotive and passenger car. The domestic hydraulic shock absorbers exposed to the problems of unstable quality and performance such as oil leakage and connector damage during long-term operation, especially the problem of homemade hydraulic shock absorbers after speeding up More, unable to meet the speed requirements, you need to import from abroad. In order to achieve domestication of hydraulic shock absorbers at an early date, to replace imported products and improve the manufacturing level of rolling stock in China, Qishuyan
