Development and present situation of dowty retarder Technology

With the development of railway transportation, the marshalling stations and section stations have been modernized, and the dowty retarder has been widely used.

In the process of using dowty retarder, with the increase of using time and the influence of other factors, the performance index of dowty retarder will change, and the brake power will be reduced. Once the braking work is not normal, the rolling speed of the vehicle will not be up to the standard, which will not only interfere with the normal transportation production, but also threaten the transportation safety in serious cases.

With the wide use of dowty retarder, dowty retarder detection technology is becoming more and more important in railway transportation.The speed control technology research units of Shanghai railway station and Harbin Railway Bureau invested tens of millions each to establish test bases, and conducted comprehensive research on the whole life cycle of the retarder. Our country has also formulated corresponding standards to provide standards for the development of detection technology of dowty retarder.
