Make physical examination for dowty retarder

The microcomputer controlled dowty retarder is a kind of dowty retarder. It is controlled by the computer to connect the cable and the solenoid valve to control the combination of the sliding oil cylinder, which plays a role in regulating the speed of the vehicle. Its internal mechanism is more precise, and it is more difficult to maintain than the ordinary dowty retarder.

In spring, the temperature changes from day to night, and some equipment is prone to "disease" due to temperature difference, which causes hidden danger to transportation and production safety. In order to effectively improve the quality of equipment and ensure driving safety, under the premise of epidemic prevention and control, a special leading group was set up to conduct on-site investigation and investigation of seasonal potential equipment problems, carry out detailed spring work, organize dowty retarder in the comprehensive workshop to shorten the inspection and maintenance cycle, increase the inspection intensity, and ensure that the on-site equipment is "timely treated in case of disease, and healthy in case of disease".

In winter, the snow remains in the area of dowty retarder line arranged by the third operation site and the passenger train station in case of continuous heavy snow in spring. During the day, the snow water enters into the pit and forms ice at night. The problem of hard roof and sliding oil cylinder failure is easily caused by the freezing in the shell of dowty retarder. The maintenance quantity of controllable roof increases sharply due to the problem of water accumulation every day, which directly affects the driving safety.
