Optimization of Power Arrangement Concept for Non-Self-Propelled Grab Dredger
The grab arrangement of traditional non-self-propelled dredgers is power supplied by turbocharged diesel engine,and via mechanical transmission to drive the grab for carrying out the dredging&dumping operations.During operation,usually,there exist some problems such as the unstable speed of the diesel engine,the unbalanced or insufficient power transmission,resulting in the occurrence of smoking from diesel engine and abnormal closing of grab.By studying and analyzing the compatibility between the working mode of dredger grab and the working characteristics of turbocharged diesel engine,this paper puts forward the optimized scheme of grab power configuration,and solves the abnormal problems such as black smoking from diesel engine.
