| description | At present time most rolling stock failures on domestic railway transport are induced by the absence of adequate diagnostics of the equipment technical condition. Record of operating indices is a manual one, representing extracts from standard reports of locomotive service. Meanwhile annual losses due to degradation of cooling equipment performance can amount to 6 - 7 t of diesel fuel per diesel locomotive unit. The paper contains review and analysis (covering inter alia advantages and disadvantages) of the known objective and subjective techniques to determinate quantitative constituent of reduction in the cooling system operating efficiency. There is drawn conclusion that the existing techniques are appropriate in identifying diesel locomotives with cooling equipment technical condition much inferior to the permitted one. Otherwise diagnostic measures’ labour input becomes unreasonably high. So in the absence of reliable on-line monitoring tools the development of special-purpose on-line techniques and tools for heat-dissipating capacity diagnostics of diesel locomotive cooling equipment is needed, considering diesel engine intermittent operation with a large proportion of transient phenomena. There are presented guidelines for the development of integrated determination technique of heat-dissipating capacity residue employing available up-to-date means for on-line remote diagnostics of the diesel locomotive principal operating parameters. Maintaining the required heat-dissipating capacity level of the diesel locomotive cooling equipment in operation will contribute to notable reduction in unproductive operating costs. |
