Dowty Retarder

In recent ten years, the operation practice of marshalling stations at home and abroad has fully proved that the dowty retarder, as a continuous speed control equipment for hump, has the following fo

There are two forces acting on the dowty retarder, braking work and resistance work. Braking work (absorption work) is the work done by the dowty retarder to the vehicle in the braking state.

Everyone knows the dowty retarder, but there are several kinds of dowty retarder. Today, I will introduce the double critical speed dowty retarder.

Dowty retarder is an independent closed hydraulic unit, which can automatically control the rolling speed of the vehicle without any external energy. The different speed of rolling makes the sliding c

The hump continuous speed control equipment, the dowty retarder, is a kind of hydraulic unit which can simply and easily control the speed of hump vehicles without external energy and external control

In the process of using dowty retarder, some problems are exposed, such as the unstable quality of dowty retarder, which can not completely reach the original design idea and so on.
