Description of drawings
Fig. 1 is a front view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, small waterplane area twin hull ship (SWATH) structure with separated diesel-engine cooling sea water pump of the present invention is: the Body of pillar 5 of both sides, bottom and submerged body 6 is connected in side of a ship platform 4 positions with the center axle portion 7 that is made of upper deck 1, main deck 3, wet deck 8, is provided with pontic longitudinal wall 2 in hull interior, main transverse bulkhead carries out structure and strengthens.To the generating diesel engine 10 of full height piezoelectricity net power supply be arranged on the about 5m distance in waterline 9 tops about on the platform of sheet hull.Independently diesel-engine cooling sea water pump 11 is set in the cabin body of waterline 9 bottoms, it drives by full ship low voltage network power supply, the suction inlet of separated diesel-engine cooling sea water pump 11 is positioned at waterline below 9, and outlet supplies cooling water expansion tank by connecting water pipe to the diesel engine salt water cooling system; Because the water pump suction inlet is positioned at underwater, emptying phenomenon can not take place therefore, cause breakdown of equipment.
Diesel engine does not have the sea water pump of carrying among the present invention, and sets up independently diesel-engine cooling sea water pump in the bottom, cabin, has solved suction inlet and has inhaled empty phenomenon; But produced another problem simultaneously: promptly boats and ships are in and suspend or during stopped status, how to start main generator group or harbor generator group.Generally be provided with the diesel engine of machine band sea water pump, all can directly start, directly drive sea water pump running supply refrigerated sea water along with diesel engine rotates; But there is not the diesel engine that carries sea water pump, adopted independently diesel-engine cooling sea water pump, then before diesel engine starting, must start separated diesel-engine cooling sea water pump earlier, but contradiction is, this moment is owing to be not activated diesel power generation, therefore full ship does not have electric power supply, can't start separated diesel-engine cooling sea water pump.
The present invention adopts separated diesel-engine cooling sea water pump " time difference starts method automatically " to address the above problem." time difference starts method automatically " be meant at first the main generator group directly started, and waits to start successfully that the back is converted to low voltage network by high-voltage fence, to the separated diesel-engine cooling sea water pump power supply, and starts separated diesel-engine cooling sea water pump supply refrigerated sea water automatically.
" time difference starts method automatically " of separated diesel-engine cooling sea water pump may further comprise the steps:
The first step: start generating diesel engine: with the comperssed air starting generating diesel engine of air bottle;
Second step: electrical generator is powered to high-voltage fence: when the generating diesel engine rotating speed was added to rated speed of rotation 1500r/min, voltage also was raised to rated voltage 690V thereupon, and electrical generator begins formal generating, and this moment, automatic closing was to the 690V mains supply;
The 3rd step: high-voltage fence is depressured to 400V by power transformer transformation to the high-tension current of low voltage network: 690V by power transformer, from trend 400V mains supply;
The 4th step: start independently diesel-engine cooling sea water pump: independently the diesel-engine cooling sea water pump electric cabinet obtains the 400V mains supply, trigger actuator and start sea water pump automatically, valve member on the sea water piping system all is arranged on opening this moment, immediately to the relevant saltwater system supply refrigerated sea water of diesel engine.
A time difference when the startup method of " time difference starts method automatically " has been utilized diesel engine starting: in the diesel engine starting process, rotating speed does not also reach rated speed of rotation, the running of machine band fresh water pump is cooled off for fresh water to the fresh water circulating system of closed cycle, and it is very short during this period of time, the diesel cylinder sleeve temperature rise is slow, the fresh water temperature is very low, even without cooled with seawater diesel cylinder sleeve is rapidly heated; In case rotating speed reaches rated speed of rotation, independently diesel-engine cooling sea water pump immediately electric startup and the supply refrigerated sea water.Though whole this process seawater is come late a bit, and diesel engine is had no effect.During practical operation, start to generating from main generator in advance, start independently diesel-engine cooling sea water pump more automatically, pump into refrigerated sea water and enter the diesel engine normal working, whole process is no more than 1 minute.
