"dehong Wheel Design And The Use Of A Number Of Technical Economic Issues Study

In recent years, with the rapid development of the international economic and technology, it is very important and necessary to develop powerful tug in order to meet the ocean-shipping market.The article mainly analyzes its advanced technology and reasonable economic of the tug of "dehong ", at the same time, the paper gives some important conclusions. Firstly, as for its technology, "dehong" adopts some advanced devices, such as CPP feathering, mean sea water for cooling system, electronic nautical chart, oil burning boiler, axis belt generator, bow-stern side-pushing, etc. Secondly, as for its economic, the paper mainly analyzes the property of saving energies of its oil burning boiler and axle generator. Thirdly, the paper gives emphasis to analyzes its bitt-towing- power-experiment and the layout of signal equipment, etc.Based on above analysis, the article covers five charpters:The first chapter is "bringing up question", It gives the study subject of this paper.The second chapter is "the present status and developing tendency of ocean rescuing tugboat ", it make a gross study of the present status and developing tendency of our ocean-rescuing-tugboat, in order to provide some references for settling up the problems of designing and building powerful rescuing-tugboat.The third chapter is "the demonstration of technology and economic of CPP-feathering ", it emphasized on the demonstration of designing of the CPP-feathering", mainly includes two parts: one is the general demonstration of its technology and economic, the other is the emphasis demonstrations of the designing of the shafting. At the last , author also gives some own viewpoints about it.The fourth chapter is "the designing of saving energy", based on the theory of saving energy, the "dehong" designs new heat-oil-control system and axle generator, the author also gives some viewpoints of applying of the oil burning boil.The firth chapter is "other questions of designing of the "dehong"", it makes a study of of its bitt-towing- power-experiment and the layout of signal equipment according the property of salvation.Directed by Dr.Shi Xin...
