Abstract
The utility model relates to a main power generating set cooling system for a crane ship. The cooling system is characterized in that the cooling system comprises a low temperature freshwater cooler (1), a high temperature freshwater cooler (2), a main power generating set diesel engine (3), a diesel engine lubricating oil cooler (4), a diesel engine cylinder sleeve water cavity (5), a low temperature water expansion tank (6) and a high temperature water expansion tank (7), wherein the main power generating set diesel engine (3) comprises a diesel engine low temperature freshwater pump (3.1), a diesel engine high temperature freshwater pump (3.2), a diesel engine air cooler low temperature freshwater end (3.3) and a diesel engine air cooler high temperature freshwater end (3.4). The cooling system adopts a closed circulating cooling system, compared with an open cooling circulating system, reliable working temperature of heated parts is guaranteed, the temperature difference of the freshwater after passing in or out of the main generating set diesel engine is small, the heat that is taken away by cooling water is reduced, and the economical efficiency of the main generating set diesel engine is improved.
Description
Technical field
The utility model relates to a kind of cooling system, relates in particular to a kind of main generator group cooling system of pontoon crane.
Background technique
In marine petroleum development, salvage and relief etc. are built in the work progress, the pontoon crane key equipment that is absolutely necessary.Yet the main generator group of pontoon crane in the past adopts open circulation cooling system mostly, when part reliably working temperature is heated in assurance, the temperature difference is bigger behind the fresh water turnover main generator group diesel engine, and the heat that the water that is cooled is taken away is bigger, makes that the Economy of main generator group diesel engine is lower.
Summary of the invention
In order to overcome above-mentioned deficiency, the temperature difference was less after the utility model provided a kind of fresh water turnover main generator group diesel engine, made the main generator group cooling system of the pontoon crane that the Economy of main generator group diesel engine is higher.
The purpose of this utility model is achieved in that
The main generator group cooling system of the utility model pontoon crane, comprise low temperature fresh-water cooler, high temperature fresh-water cooler, main generator group diesel engine, diesel engine oil cooler, diesel cylinder sleeve water cavity, low temperature water swelling water tank and high-temperature water swelling water tank, described main generator group diesel engine comprises diesel engine low temperature fresh water pump, diesel engine high temperature fresh water pump, diesel air cooler low temperature fresh water end and diesel air cooler high temperature fresh water end.
Described low temperature fresh water cooling tube is communicated with low temperature fresh-water cooler, diesel engine low temperature fresh water pump, diesel air cooler low temperature fresh water end and diesel engine oil cooler successively, gets back to the low temperature fresh-water cooler at last, has formed the enclosed low temperature fresh water circulatory system.
Described high temperature fresh water cooling tube is communicated with high temperature fresh-water cooler, diesel engine high temperature fresh water pump, diesel air cooler high temperature fresh water end and diesel cylinder sleeve water cavity successively, gets back to the high temperature fresh-water cooler at last, has formed the enclosed high temperature fresh water circulatory system.
Low temperature fresh water cooling tube before described low temperature water swelling water tank and the diesel engine low temperature fresh water pump is connected, and the preceding high temperature fresh water cooling tube of described high-temperature water swelling water tank and diesel engine high temperature fresh water pump is connected.
The beneficial effect that the utlity model has is:
The main generator group cooling system of the utility model pontoon crane has adopted closed circuit cooling system, it is compared with open circulation cooling system, guaranteed to be heated under the temperature of part reliably working, the temperature difference is less behind the fresh water turnover main generator group diesel engine, the heat that the water that is cooled is taken away reduces, and the Economy of main generator group diesel engine is improved.
