Dowty Retarder

I don't know if you have any idea about the "false dowty retarder" of dowty retarder. Let's introduce how the "false dowty retarder" of dowty retarder is.

In the process of vehicle pulling out, when the speed is too fast or the locomotive suddenly accelerates and decelerates, the instantaneous impact force of the wheel on the dowty retarder increases si

How to use the hydraulic oil of the dowty retarder correctly has a great effect on the working efficiency of the dowty retarder and prolonging the service life. It also plays a significant preventive

One of the faults is that they cannot be stepped down no matter how hard they are used, and they cannot slide freely, forming the so-called "dead dowty retarder".

Therefore, it is not required that each dowty retarder must meet The ambient temperature specified above. Therefore, the new standard cancels the requirement for ambient temperature.

Under normal use and maintenance conditions, the service life of ordinary dowty retarder and controllable items (including control valves) should not be less than 3 million cycles or 6 years, whicheve
