Abstract

The invention discloses a self-protection starting system of a marine diesel engine s, which comprises a starting mechanism, a barring mechanism, a speed reducing mechanism, a clutch mechanism, a detection module, a processing control module and an alarm module; the starting mechanism is elastically connected with the barring mechanism through the speed reducing mechanism and the clutch mechanism;the detection module is connected with the processing module and used for obtaining state information of the marine diesel engine in the barring process and the blowing process; and the processing module is connected with the alarm module and feeds back whether the marine diesel engine is started abnormally or not according to the state information obtained by the detection module. According to the self-protection starting system of the marine diesel engine provided by the invention, a method of embedding barring abnormality detection and diagnosis into the blowing starting process is adopted, no man-made interruption in the diesel engine starting process is realized by utilizing the speed reducing mechanism and the clutch mechanism, and self-protection in the diesel engine starting process is realized through the detection module and the processing control module, so that the marine diesel engine realizes active abnormality troubleshooting before starting, normal starting conditionsare met, and the purpose of safe starting is ensured.

Description

technical field [0001] The invention relates to the technical field of ship protection systems, in particular to a ship diesel engine self-protection starting system and a starting method thereof. Background technique [0002] The starting of a marine diesel engine is the working process of turning the diesel engine from a static state to a running state. It must rely on external energy to drive the crankshaft to rotate and drive the piston to compress and work to complete the working cycle and achieve the purpose of continuous output torque. At present, there are generally two starting methods for marine diesel engines: electric starting and compressed air starting. The marine diesel engine usually needs to drive the crankshaft to rotate several times through the cranking mechanism before restarting after stopping for a certain period of time to check whether there are abnormal conditions such as friction, collision and sticking that hinder the normal operation of the main ...
