How to reduce the failure rate of railroad fasteners

Due to the high speed of trains, high-speed railways must have the following characteristics in addition to requiring the elastic parts of subway and railway fasteners to have sufficient buckling force, equivalent elastic range and strong ability to maintain gauge. Once the high-speed railway is opened, due to the high speed and high density of trains, railway track maintenance can only be carried out within a short blockade. This requires the components of the rail fastenening system to have sufficient strength and durability.

Railroad fasteners have good noise reduction and vibration reduction performance. With the increase of train speed, the effect of track dynamics has increased sharply, so subway and railway fasteners are required to have good noise reduction and vibration reduction performance, that is, fasteners are required to use better elastic cushion rubber pads. In order to ensure the absolute safety of high-speed railways, railroad fasteners are required to have good insulation properties, and there should be sufficient impedance between the two steel rails to ensure the normal operation of the railway track circuit. The boltless rail clip Ⅲ type fastening system has fewer parts and is easy to load and unload. From a long-term point of view, it can greatly reduce maintenance and repair costs. Rail clips The subway and railway fastening system must use plastic screw dowels instead of sulfur anchoring to meet the requirements of high-speed railway ballasted tracks. Moreover, the structure of the rail clips Ⅱ fastening system, the bolts are bent, the plastic screw dowel enters water and the dirt is not easy to solve. To prevent rail bolts from rusting, other protective measures must be taken. However, these problems are not present in the rail III fastening system.

In order to ensure the safety of railways, railway fasteners need to be inspected and maintained regularly. In addition, reasonable maintenance methods are required to reduce the failure rate of railway fasteners. Kingrail Parts has been producing and providing various railway fasteners for many years, with a complete range and reliable quality.
