FIELD: railway transport.
SUBSTANCE: invention relates to preparation of rolling stock for inspection and flow detection in winter. To remove snow and other crusts or oil-mud deposits from bottom of passenger or freight car by jet method use is made of air with temperature from +50°C to +120°C at pressure of 8 - 12 atm, gauge, flow rate of 5 - cu.m/min and velocity of 2-5 m numbers, with provision of gas-dynamic and acoustic shock waves. Gas can be used as alternative to air which is delivered at temperature lower than ambient temperature and frequency equal to frequency of natural vibrations of snow mass on surfaces of wheelsets provided by intensification of liquid nitrogen.
EFFECT: improved quality of cleaning of bottom part of passenger or freight car.
