Problems solved by technology
One is the delay of lubrication on curved road sections. The curve sensor detects that the most severe wear between the wheel and rail has begun when the locomotive enters the curve; the other is the limitation of the viscosity of lubricating oil, which cannot be applied Better High Viscosity Grease
[0004] For the above technical problems, there is no good solution in the prior art

The invention relates to the field of lubrication of locomotives, and discloses an anti-attrition lubricating system for a locomotive wheel track. The system comprises a controller, and a lubricating pump and a control valve which are connected with the controller, and an energy accumulator and an oil spraying valve which are connected with the lubricating pump through a first pipeline, wherein the oil spraying valve is connected with the control valve through a second pipeline; the controller is used for sending a signal to the control valve to open or close the second pipeline through the control valve, and receiving a signal from a sensor of the oil spraying valve to monitor a working condition of the system; the oil spraying valve is used for spraying lubricating oil in the first pipeline to a lubricating part of the locomotive wheel track when the second pipeline is opened; the lubricating pump is used for conveying pressure lubricating oil into the first pipeline; and the energy accumulator is used for accumulating pressure energy in the first pipeline. Due to the technical scheme, the energy accumulator is arranged on the pipeline where the pressure lubricating oil exists, so that the pressure of the system can be accumulated, and the system can operate continuously.
Description
technical field [0001] The invention relates to the field of railway locomotive lubrication, in particular to a locomotive wheel rail anti-friction lubrication system. Background technique [0002] In order to solve the wear and tear of the wheel and rail during locomotive operation and reduce the risk of wheel derailment, Tranergy Corporation of the United States, Gulf Oil International, and Texaco Research and Development Center jointly developed a new vehicle-mounted wheel and rail lubrication system—— SENTRAEN 2000. Western European countries still use the thin oil lubrication method containing extreme pressure and anti-wear additives. Due to the long pipeline of the fuel injection device, it is often difficult to pump in winter and cause locomotive pollution in summer. The most widely used in China is the HB series wheel-rail lubrication device developed by the Ministry of Railways Science Research Institute and the Chemical Research Institute. This lubrication device ...
