Abstract
The utility model discloses a diesel generator of an ocean platform engineering ship, which comprises a diesel engine and an electric ball, wherein a gear box is installed between the diesel engine and the electric ball, the power output end of the diesel engine is in drive connection with the electric ball via the gear box, and the flywheel end of the diesel engine is in drive connection with required load on the ship. The diesel generator is capable of fully utilizing the output power of the diesel engine and reducing the cost of the ship raw materials, and a series of diesel engines with small cylinder diameters is selected for both satisfying the grid power generation demand and driving the high power required load on the ship.
Description
Technical field
The utility model relates to the dynamo-electric configuration of boats and ships, particularly the platform auxiliary vessel diesel-engine generator of platform engineering diesel-engine generator configuration.
Background technology
When the dynamo-electric configuration of boats and ships type selecting; Often run into same serial diesel engine the also different situation of different rated speed of rotation and power is arranged; Limited by the boats and ships frequency of utilization; Often can only select all diesel engines of satisfactory that model of rotating speed lower but frequency and power, and take to select the way of the diesel engine of big cylinder diameter series sometimes for the power requirement that satisfies the particular boat project, at this moment select for use rotating speed lower but frequency and power all the diesel engine of satisfactory that model just can not satisfy actual needs; Must select the diesel engine of big cylinder diameter series for use, thereby cause cost significantly to increase.
Summary of the invention
To the deficiency that exists in the prior art, the purpose of the utility model is to provide a kind of platform auxiliary vessel diesel-engine generator that can make full use of the horsepower output of diesel engine and reduce the boats and ships cost of raw material.
The technical scheme of the utility model is achieved in that platform auxiliary vessel diesel-engine generator; Comprise diesel engine and electric ball; Between said diesel engine and said electric ball, gear case is installed; The clutch end of said diesel engine is connected with said electric ball driving through said gear case, and the demand load driving is connected on the flywheel end of said diesel engine and the ship.
Above-mentioned platform auxiliary vessel diesel-engine generator, said gear case is a reducing gearbox.Make the needs that can satisfy the generating online at the diesel engine of selecting less cylinder diameter series for use, demand load on simultaneously again can the driving power bigger ship.
Above-mentioned platform auxiliary vessel diesel-engine generator, the flywheel end of said diesel engine is connected through demand load driving on power-transfer clutch and the ship.
Above-mentioned platform auxiliary vessel diesel-engine generator, the rotating speed of said diesel engine is 1800rpm, and the rotating speed of said electric ball is 1500rpm, and the reduction ratio of said reducing gearbox is 1.2:1.
The beneficial effect of the utility model is: the platform auxiliary vessel diesel-engine generator of the utility model can be selected higher that diesel engine of rotating speed at work, makes full use of the horsepower output of diesel engine, thereby reduces the boats and ships cost of raw material; Especially for the platform auxiliary vessel, dynamo-electric configuration itself is just complicated, can save many costs of raw material to electromechanics optimization.That is: can take to select for use that model (higher that model of power in the same train) of the bigger or maximum rated rotating speed of specific cylinder diameter serial diesel engine, thereby obtain best diesel engine horsepower output for platform auxiliary vessel project configuration; Optimize dynamo-electric configuration, realize that the diesel engine of platform auxiliary vessel diesel-engine generator can be exported different rotating speed; Make the needs that can satisfy the generating online at the diesel engine of selecting less cylinder diameter series for use, demand load on simultaneously again can the driving power bigger ship, thus significantly reduced the raw-material cost of boats and ships.
Description of drawings
Fig. 1 is the structural representation of the utility model platform auxiliary vessel diesel-engine generator.
Among the figure: demand load on 1-diesel engine, 11-clutch end, 12-flywheel end, 2-electricity ball, 3-gear case, the 4-ship.
The specific embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1; Present embodiment platform auxiliary vessel diesel-engine generator comprises that rotating speed is that the diesel engine 1 of 1800rpm is the electric ball 2 of 1500rpm with rotating speed; Between said diesel engine 1 and said electric ball 2, gear case 3 is installed; The clutch end 11 of said diesel engine 1 drives with said electric ball 2 through said gear case 3 and is connected, and the flywheel end 12 of said diesel engine 1 passes through that demand load 4 drivings are connected on power-transfer clutch and the ship.Said gear case 3 in the present embodiment is a reducing gearbox, and its reduction ratio is 1.2:1.
Present embodiment platform auxiliary vessel diesel-engine generator can be selected higher that diesel engine of rotating speed at work; Promptly can take to select for use that model (higher that model of power in the same train) of big rotating speed of specific cylinder diameter serial diesel engine or maximum rated rotating speed; Said like this diesel engine 1 both can drive the 2 generating online of said electric ball, load 4 on again can the driving power bigger ship.Make full use of the horsepower output of diesel engine, make platform auxiliary vessel project configuration obtain best diesel engine horsepower output, optimize dynamo-electric configuration, reduce the boats and ships cost of raw material.
For example; Certain is newly made in the platform auxiliary vessel project; Need use a diesel engine and export demand load 4 uses on about 580KW power confession ship; Configuration only had three 450KW50Hz on the ship at that time; The generator set of 1500rpm can supply to revise, and these several generator seies all have been this rotating speed (A1 model) maximum power configuration down in this series (A series), changes the diesel engine of a big cylinder diameter series (B series) or selects that machine (about exportable 600KW1800rpm) of the bigger rotating speed of this series (A2 model) for use.Green phase closes mechanical & electrical technology man analysis research; Decision to these three generator seies wherein one transform; Adopt this diesel engine of A series A 2 models; Convert 1500rpm to through reducing gearbox again and drive electric ball 2 composition diesel powerplant generating online, guarantee to adapt with this network of ship voltage electricity system.The A1 price was at 9.5 ten thousand dollars/platform at that time; The A2 price is at 9.8 ten thousand dollars/platform; The B price is greater than 17.8 ten thousand dollars/platform; Increase gear case 3 packages and install 20,000 dollars of prices, select for use the combination of diesel engine and the gear case 3 of A2 model to save about 60,000 dollars than the diesel engine direct materials cost of selecting Type B number for use; And the boats and ships ancillary system of B serial diesel engine is than serial much complicated of A, the laid down cost of optimized choice A2 also can corresponding minimizing some.
The foregoing description only be for explain clearly that the invention does for example, and be not qualification to the invention specific embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the invention claim.
