Braking systems of trains

Thus, the charging pressure of 4.7 kg/cm2 provides the necessary pressure in the brake cylinder when exiting the rod within the established norms laden mode, given the saturation of the freight wagon fleet composite blocks and their operation mode in the middle allowed the pressure in the brake line of the tail Train 4.5 kg/cm2 (usually a sufficient time in transit, this pressure will increase by 0.2-0.3 kg/cm2). In addition, the pressure in the line during braking is provided 3.5 kgf/cm2 required to complete the course of the main piston diffuser to reduce line pressure range of 1.2 kg/cm2 (4,7-3,5). The value of the pressure in the rear of the train depends on its length, leaks, and leaks along the distribution line.

The greatest pressure drop provide a leak in the rear of the train, as the compressed air compensates them overcome the greatest resistance and has a maximum loss of energy. The smallest impact on the drop have a leak in front of the train. As for the compressor engine, the impact of leaks on her work does not depend on their location.
