Embodiment

[0022] Example: such as figure 2 As shown, the locomotive diesel engine air starting system is an air pipeline, the output end of the air source device is connected to the input end of the control circuit and the main circuit at the same time, and a pressure detection device is connected to the input end of the control circuit and the main circuit. The pressure detection device is a pressure sensor 14, which is used to detect the pressure of the total air cylinder. The air source device is composed of auxiliary air compressor 1, safety valve 2, check valve 1 3, check valve 2 4, air cylinder 5 with drainage device 6, and the function of drainage device 6 is to discharge possible air in the air cylinder 5. The presence of liquid water protects the air cylinder 5 while preventing corrosion of equipment in the air starting system. The air cylinder 5 is used to store the compressed air generated by the air source device and provide power for the air starting. The output end of th...

Abstract

The invention discloses an air starting system of a locomotive diesel engine. The air starting system of the locomotive diesel engine is an air pipeline. The output end of a wind source device is connected with the input end of a control loop and the input end of a main loop at the same time; and a pressure detection device is connected with the input end of the control loop and the input end of the main loop. The air starting system of the locomotive diesel engine has the advantages that components are simple, the cost and maintenance cost are low, and the daily maintenance is only replacement of a small gear, so that the problems that the cost and maintenance cost of a starting moot and a storage battery are high as the diesel storage battery drives the direct-current starting motor to drive the diesel engine are solved. When an auxiliary compressor driven by the storage battery works, the load of the storage battery is very small, and the service life of the locomotive storage battery is not affected. A microcomputer is adopted to control the starting process more accurately, and an electromagnetic valve and a pressure switch are used cooperatively, so that the intelligent degree is improved.

Description

technical field [0001] The invention relates to a diesel engine starting system, in particular to a diesel engine starting system for locomotives, belonging to the field of locomotives. Background technique [0002] At present, domestic diesel locomotives are mostly diesel locomotives with medium-speed diesel engines as the power source. If the locomotive wants to get power, the diesel engine must be started. The starting mode of the diesel engine directly affects the maintenance and performance of the diesel locomotive. [0003] Existing scheme 1: The locomotive adopts the starter motor to drive the diesel engine to start. That is to say, the locomotive is equipped with a battery, which provides power to the starter motor, and the starter motor drives the diesel engine. When the number of revolutions of the diesel engine reaches the self-running level, the starter motor stops working, thereby completing the start of the diesel engine. But still there is following shortco...
