Embodiment
The present invention is described further by reference to the accompanying drawings:
As shown in Figure 1, the control gear that the present embodiment diesel generator of ocean platform engineering ship drives external fire water pump comprises diesel generator, external fire water pump 4, outer Fire Fighting Pump Control device 6 and ship power management system 7, described diesel generator comprises that rotating speed is the diesel engine 1 of 1800rpm and the electric ball 2 that rotating speed is 1500rpm, gear-box described in the gear-box 3(present embodiment 3 is installed between described diesel engine 1 and described electric ball 2 is reduction gear box, its reduction speed ratio is 1.2:1), the clutch end of described diesel engine 1 drives with described electric ball 2 by described gear-box 3 and is connected, and the flywheel end of described diesel engine 1 drives with described external fire water pump 4 by clutch 5 and is connected.Described control gear also comprises; Described outer Fire Fighting Pump Control device 6 respectively with the communication connection of the control actuator of described external fire water pump 4, described clutch 5 and described diesel engine 1, described ship power management system 7 respectively with the control actuator communication connection of described diesel engine 1, described gear-box 3 and described electric ball 2.
As shown in Figure 2, when not needing fire-fighting, described ship power management system 7 control diesel generators start to be incorporated into the power networks shuts down with off-grid; When the needs fire-fighting, described ship power management system 7 at first is to receive the fire-fighting demand signal, and then locking is sent to described outer Fire Fighting Pump Control device 6 simultaneously and can be entered the fire mode signal the control of diesel generator.After described ship power management system 7 is received the fire-fighting demand signal, at first analyze and whether judge diesel generator in the net generating, if then do not send actuating signal to diesel engine 1 in the net generating, then locking is to the control of diesel generator; If then judge whether transship after load is shifted in net generating: if off-the-line after nonoverload then load are shifted, locking is to the control of diesel generator again, whether transship if transship then judge after one-level unloads, if nonoverload then carries out one-level unloading, the rear off-the-line of load transfer and locking to the control of diesel generator, if overload then provides the prompting that can't enter fire mode after the one-level unloading after the one-level unloading.Described outer Fire Fighting Pump Control device 6 receives and can enter the signal that the backward described diesel engine 1 of fire mode signal sends adjusting rotary speed, the rotational speed regulation of described diesel engine 1 is after the scope of setting, described outer Fire Fighting Pump Control device 6 sends actuating signal to described external fire water pump 4 and described clutch 5 respectively, the most backward described diesel engine 1 sends the signal that accelerates to rated power, drives described external fire water pump 4 and realizes fire-fighting function.
For example, newly make in the ocean platform engineering ship oceangoing ship project at certain, be applied to the corresponding power of a diesel engine 1 maximum output speed and drive external fire water pump 4, and this diesel engine 1 the other end drives electric ball 2 generatings by reduction gear box, needs the power stage of this diesel engine 1 is carried out special control to realize auto-parallel, off-grid and external fire-fighting function.By relevant mechanical ﹠ electrical technology man analysis research, determine this diesel engine 1 power stage is controlled, step is as follows: 1, this diesel generator can be used as the normal power generation machine and starts for ship power management system control and be incorporated into the power networks and off-grid is shut down at ordinary times; 2, when the needs fire-fighting, a) ship power management system judges that by analyzing also locking is to the control of this diesel generator, send simultaneously and can enter the fire mode signal, b) regulate diesel engine 1 rotating speed to OK range, c) start clutch 5 and drive external fire water pump 4, realize fire-fighting function thereby d) accelerate to rated speed.This controlling method has realized the rationally effectively control of the external fire water pump 4 of diesel generator band, provides reliable foundation to the configuration of this kind diesel generator.
The present embodiment diesel generator of ocean platform engineering ship drives the control gear of external fire water pump can select higher that diesel engine of rotating speed at work, namely can take to select that model (higher that model of power in the same train) of the larger rotating speed of specific cylinder diameter serial diesel engine or maximum rated rotating speed, described like this diesel engine 1 both can drive the 2 generating online of described electric ball, load 4 on again can the driving power larger ship.Take full advantage of the output power of diesel engine, make the ocean platform engineering ship project configuration obtain best diesel engine output power, optimize dynamo-electric configuration, reduce the boats and ships cost of raw material.
For example, certain is newly made in the ocean platform engineering ship project, need to use a diesel engine and export about 580KW power for external fire water pump 4, configuration only had three 450KW@50Hz on the ship at that time, the generator set of 1500rpm can be for revising, and these several generator set all have been the lower peak output configuration of this rotating speed (A1 model) in this series (A series), change the diesel engine of a large cylinder diameter series (B series) or select that machine (about exportable 600KW@1800rpm) of the larger rotating speed of this series (A2 model).By relevant mechanical ﹠ electrical technology man analysis research, decision to these three generator set wherein one transform, adopt this diesel engine of A series A 2 models, convert 1500rpm to by reduction gear box again and drive electric ball 2 composition diesel generator 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-box 3 packages and install 20,000 dollars of prices, the combination of selecting the diesel engine of A2 model and gear-box 3 is saved about 60,000 dollars than the diesel engine direct materials cost of selecting Type B number; And the auxiliary system of B serial diesel engine is much complicated than A series, construction cost that optimize to select A2 also can corresponding minimizing some.
Above-described embodiment only is for the invention example clearly is described, and is not the restriction to the invention embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the invention claim.
