Description
Technical field
The utility model relates to a kind of pick-up unit, particularly relates to a kind of real-time measurement analysis device of marine main engine fuel consume that is used for oil consumption process analysis procedure analysis and administration of energy conservation.
Background technology
According to statistics, the finished diesel fuel of China refining more than 25% by boats and ships consumption.At present also not to the shipping boats and ships oil consumption carry out science, meticulous measurement and control, the economy that fuel oil utilizes is not high, makes to enterprise and brings very big economic loss.Show that according to interrelated data fuel cost accounts for more than 1/3 of ship operation income, the Large Container Ship of a 5000TEU, the standard oil consumption of every day is about 110 tons; And one navigated by water in the Changjiang river and the diffusing break-bulk carrier of 3000 deadweight capacities in tributary, and also about 300 tons, fuel cost accounts for the 40-60% of revenue from transportation to the diesel consumption in 1 year.From shipping enterprise's aspect, oil consumption is the major part of operating cost, and ship energy saving is one of main direction of saving cost.
The ship energy saving measure can be considered from managing energy-conservation and two aspects of technical energy saving.
Aspect technical energy saving, whole nation transportation industry is also in some advanced fuel-economizing experiences of popularization, " learning good fuel-economizing " method as Qingdao Harbour " No. two, Asia " tugmaster Zhou Xueliang, by using his long-term method of summing up of a cover, " No. two, Asia " wheel was saved 159.5 tons of fuel oils in 2006 to 2007, convert 87.7 ten thousand yuan of fuel-economizings by oil price at that time, the fuel-economizing achievement is quite outstanding.But following reason causes this fuel saving method to be difficult to popularize, one, and these boats and ships do not have general representativeness, and craft tug operation waters is little, sea situation is relatively stable, back and forth travels on a bit of circuit for a long time, is convenient to find out rule.And most shipping boats and ships all have the characteristics that haul distance is long, the course line is wide, Channel Condition is changeable, can't adopt same method summary to go out experience; Its two, very general to the introduction of experience, the data of lack enriching do not have quantitative process analysis procedure analysis, basic skills is nothing but to reduce distance to go, utilize economical speed, bring into play the common knowledge such as identity of ship the biglyyest.And we lack is not these general knowledge, but how these knowledge economy ground is used for practice.Promptly how to calculate the identity of ship relevant, how to determine economical speed,, find out rule, only just can not accomplish by rule of thumb because the variation of Channel Condition is very big to their influence with oil consumption.Therefore, popularizing the basic method of boats and ships fuel-economizing is that the oil consumption process of diesel engine is measured and analysis-by-synthesis dynamically,, and then analyzes and uses as foundation with accurate data.And the present fuel consumption measurement instrument that still is not applicable to boats and ships.Cause the crewman very fuzzy to the consumption process understanding of navigation intermediate fuel oil, or even wrong, this also is the bottleneck place that ship energy saving is difficult to deep popularization.
