Why do we need to develop an intelligent dowty retarder

Since the use of dowty retarder. There is no effective method for accurate detection of various performance indicators of dowty retarder. Most of the reduction roof repairs use a combination of outdoor inspection, outdoor maintenance and indoor maintenance. In the maintenance work, the daily inspection of dowty retarder accounts for a large proportion. The inspection of the dowty retarder installed in the marshalling yard takes about 60% of the maintenance work on average every day, which is time-consuming and labor-intensive. The method commonly used by maintenance personnel is manual inspection, visual inspection for external structure damage, oil leakage and other phenomena. Whether the dowty retarder does work or the braking performance can only be judged by stepping on the feet. And because the human factors are not in place, it is easy to cause a shunting accident. In some marshalling yards, a partial deceleration has appeared. Although it is not within the maintenance period, the braking function is significantly reduced. The critical speed changes, so that overspeed linking frequently occurs. Damage to the vehicle. But it is impossible to accurately detect these non-working deceleration jacks among thousands of deceleration jacks. With the extension of the use time of dowty retarder, the performance of the equipment continues to decline. Application quality declines. This problem has also become increasingly prominent, becoming a hidden danger of marshalling yard shunting operations and personal safety.

For these reasons. We need to develop intelligent dowty retarder. It makes it possible to accurately detect whether dowty retarder installed on the line does work itself, timely find the unqualified dowty retarder, replace it in time, eliminate hidden dangers of accidents, and ensure the safety of railway transportation production.
