The purpose and significance of the dowty retarder research

The dowty retarder is a hydraulic device that is installed on the steel rail to decelerate the moving vehicle by sliding the cylinder cap. It is a kind of hydraulic equipment that does not require external energy, does not require external control, and can more accurately control the speed of the rolling vehicle. It consists of a plurality of hydraulic units arranged on the line according to the design scheme, and continuously acts on the wheel treads to achieve the purpose of accelerating or decelerating the vehicle.

Dowty retarder speed control equipment has the advantages of small investment, high accuracy, safety and reliability, no external energy, easy maintenance, etc. It does not require external energy in the railway field of all countries in the world, and is easy to maintain. It has the value in the railway field of all countries in the world. Economic value is a very meaningful thing.
