Large-scale diesel engine can be with diesel oil, coal gas oil or heavy oil work.This title relates to working procedure, and it is to characterize through sucking air and the spontaneous combustion after spraying into fuel according to definition.
The two-cycle engine great majority are configured to machine in upright arrangement, and four stroke engine is mainly arranged with array and constructed as the V-type engine layout.In big marine diesel engine, relate generally to two-cycle engine, it is constructed with the in line engine of 5 to 14 cylinders, and opposite less marine diesel engine majority is a four stroke engine.Marine diesel engine generally is designed to low-speed machine.Rotating speed is arranged in 60 to 130 rev/mins scope under the situation of two-cycle engine.Large-scale diesel engine reaches the fuel consumption that is lower than 180g/kWh.
Need a series of special spare system in order to move large-scale diesel engine.If one in these systems breaks down, so also must stop the operation of large-scale diesel engine.Therefore be provided with some auxiliary devices redundantly: current device, lubricating pump, petrolift, cooling waterpump, oil hydraulic pump or the like.
Large-sized diesel motor in most of the cases has independent by electric motor driven lubricating pump.Its task is to supply with machine oil at run duration to the bearing of motor.Engine oil pressure must be kept through this external pump under the engine conditions that stops, to guarantee lubricating again accordingly motor.The lubrication piping majority is configured to bypass system, when the lubricant oil volume flow of continue being carried by pump under corresponding engine operating state when not required, through this system the lubricant oil of surplus is drained.Lubricating pump for example can be reciprocating pump or gear pump.
Large-sized diesel motor has the turbo charging installation that is used to raise the efficiency with specific power.Turbosupercharger is used for improving piston-engined power through air mass flow that improves every work cycle and fuel flow rate.Turbosupercharger is included in the exhaust gas turbine in the exhaust flow, and it is connected with compressor in the suction tude.Turbine is rotated and Driven Compressor thus by a part of exhaust flow energy of motor.Compressor improves the pressure in the suction tude of motor, thereby during the aspirating stroke than under the B type engine situation more in the air of the volume entering cylinder.Having more oxygen thus can supply the burning of corresponding more fuel quantity to use.
Usually in waste gas, leave certain dump energy (overvoltages of for example about 3 crust) this moment, it is not utilized and has lost.Current operational turbosupercharger has very high efficient, and for example 70%, and rotating speed is very high, thus their supercharging especially possibly utilized under the two-stroke large diesel engine situation fully.Seam is for example lost in the measure that therefore usually need add; Disadvantageous blade geometry structure or similar structure; Have to make the deterioration of efficiency of turbosupercharger artificially or its rotating speed is reduced, so that they are complementary with corresponding DENG through these measures.
In addition, known unnecessary exhaust energy with turbogenerator is collected through power turbine and is presented in the electrical network peculiar to vessel to ship through driving mechanism and generator in marine diesel engine.This configuration is called power turbine (Powerturbine).
The known in addition unnecessary exhaust energy of collecting through power turbine is coupled on the engine shaft through driving mechanism.But need overcome the very high speed discrepancy between power turbine and the engine shaft this moment, thereby this configuration is unreliable owing to need big driving mechanism.
Summary of the invention
Set out thus, task of the present invention is under identical or lower manufacture cost situation, to improve the total efficiency that this internal-combustion engine comprises all auxiliary devices.
This task solves through a kind of turbogenerator.Said turbogenerator comprises that at least one turbosupercharger level and at least one are used for being utilized in the power turbine of the unnecessary exhaust mass stream of turbosupercharger level branch; And comprise at least one oil pump device and a motor that mechanically be coupled with power turbine through driving mechanism and that be electrically connected with a power supply; It is characterized in that; Oil pump device mechanically is coupled on the motor and is provided with segregating unit, is used to make power turbine and electromechanics ground to break away from coupling
According to the present invention; A kind of turbogenerator is proposed for this reason; One of them oil pump device mechanically is coupling on the motor, and motor mechanically is coupling in again on the power turbine, power turbine can through the running of the exhaust flow of a turbosupercharging level top set and with a power supply electric coupling; Wherein be provided with segregating unit, be used to make power turbine and electromechanics ground to break away from coupling.
Utilize this configuration to realize converting the dump energy that exists in the exhaust flow to be used to drive oil pump device utilizable energy; This dump energy is in the state that is not utilized so far for this reason or under the situation of power turbine configuration, has been fed back on the ship of doing the power supply effect in the electrical network, and wherein the loss when converting electric energy to and converting mechanical energy to has not conversely just had.Only need a motor to replace motor and the generator that for this reason in power turbine, uses so far in order to drive oil pump device in addition.
This being configured in the above-mentioned two-stroke diesel engine in marine diesel engine, is particularly advantageous for example, and wherein the surplus power that from exhaust flow, can obtain of each power turbine is approximately corresponding to the arrangement in lubricant pump desired power of two-cycle engine.
But the present invention also can be advantageously used in the running lubricating pump in four-cycle diesel engine; Wherein especially in having the four stroke engine of two-step supercharging; Wherein only on a turbosupercharging level, be provided with power turbine, the useful horsepower of obtaining is suitable for the needed driving power of lubricating pump.Therefore for example under so-called ME h type engine h situation; Wherein outlet valve is not through camshaft but electronically through hydrodynamic body control; Can the power that sent by power turbine be used for live axle streaming reciprocating pump, hydraulic oil be in add through this pump and depress.If the power of power turbine is not enough for this reason, then can additionally from ship, obtain electric energy the electrical network.
The clutch that can handle as segregating unit setting.Under a kind of running state; Wherein power turbine does not provide or only provides very little power; Can the mechanical connection between motor and the power turbine be broken off, thereby on power turbine, not produce windage loss or do not have wasted power from electrical network, to produce and the electric energy of electrical network only is used to drive oil pump device.Not have just must to carry out standby to motor under driven situation lubricated with power turbine correspondingly because only stop at motor.And neither always guarantee on power turbine, to produce the enough high powers that are used to drive lubricating pump during the engine start.
Can be under a kind of running state through motor, wherein the underpower of power turbine obtains electric energy to drive oil pump device from power supply.Advantageously; Work converts mechanical energy to electric energy to the power situation that motor sends according to power turbine at this moment as generator; Perhaps work converts electric energy to mechanical energy as motor, thereby can unnecessary power be fed on the motor in the electrical network that is provided with as power supply.
Electrical network generally provides the Ac of constant frequency and voltage this moment, but according to the different electric current [strength or the needs of power, can be thus side by side with doing to the working method of motor with thus to arriving the adjusting of the power on the oil pump.Before reaching certain turbine power, this turbine power is caused pump-unit, and the power that wherein possibly lack obtains from electrical network.When the turbine power raising has surpassed needed pump power, then redundance is presented to electrical network.
In addition, the control gear of controlled clutch advantageously, it is in response to the Operational Limits of one or more detections, the rotating speed of turbine or motor for example, engine oil pressure and temperature or the feedback electric current [strength from the motor to the electrical network are separated controlled clutch and are connected.
Though, be also contemplated that except oil pump device and can also another auxiliary device that adds be coupled according to mode of the present invention and power turbine for the coupling of power turbine with thus in order to make full use of the device such as the oil pump device of the unnecessary significant especially continuous running of waste gas power that in continuous service, produces.
Some safety measures advantageously in addition, a system or engine controlling unit that is used for manually separating controlled clutch for example, it stops motor in response to the fault of power supply.Except the by-pass line in lubricating pipe, can unwanted lubricant oil be discharged through it, can also in the exhaust piping before the power turbine, a by-pass line be set, can waste gas be discharged when power turbine breaks down or keeps in repair through it.
The present invention gives favourable expansion scheme.
Can combination in any according to each single characteristic of the form of implementation of claim, as long as it is significant.This moment is self-evident, and the aforesaid and following characteristic that will describe can not only be used in the combination that provides but also in other combination or individually, and does not exceed scope of the present invention.
Description of drawings
Below the accompanying drawing of contrast signal is described in detail preferred implementing form of the present invention.In the accompanying drawing:
Fig. 1 has shown the frame piece figure according to a form of implementation of turbogenerator of the present invention; With
Fig. 2 has shown the energy schematic flow sheet according to the form of implementation of turbogenerator of the present invention that in Fig. 1, shows, wherein has the energy stream that draws, and is used to describe two running statees of turbogenerator.
Embodiment
Fig. 1 has shown the turbosupercharger 1 of in the exhaust piping 10 of internal-combustion engine 9, arranging, it is used for improving through supercharging the specific power of internal-combustion engine 9.Power turbine 2 is arranged in 3 neutralizations of waste gas lateral and drives through the exhaust energy that hereto is not utilized.Rotatablely moving of power turbine 2 passes to controlled clutch 5 through a mechanical connection through suitable driving mechanism 4.
On opposite side, controlled clutch 5 mechanically is coupled with motor 6.When controlled clutch 5 was on the running position, the power transmission of 6 machinery then took place from controlled clutch 5 to motor.Motor also hangs on the electrical network of ship for 6 this moments in addition, and this electrical network for example turns round through a plurality of subsequent use generator set fault-free ground and can send the electric current of constant frequencies and any power in the related power frequency spectrum to motor 6.
According to internal-combustion engine 9 and thus power turbine 2 running state and to the power transmission of oil pump 7, motor can be used to the mechanical energy of power turbine drive oil pump 7 and in the case as generator work 6 this moments.Unnecessary mechanical energy is converted into electric energy at this moment and infeeds in the electrical network 8.If be not enough to satisfy the needs of oil pump 7 from the mechanical energy of power turbine 2, then motor 6 also can be used as motor work and from electrical network 8, obtains electric energy, to satisfy the energy requirement of oil pump 7.
Fig. 2 has shown two possible in principle running statees of whole system.Running state I has shown at controlled clutch and has been under the situation of joint as the motor 6 of generator that wherein motor 6 is driven by power turbine 2.If except the power that is required by oil pump 7, also have unnecessary power, this power is imported in the electrical network 8 so.
State I I has shown at controlled clutch and has been in the running state under the situation of disengagement; Wherein motor 6 is as motor work with mechanically supply with the required energy of work of the requirement be used to guarantee oil pump 7; Because for example power turbine 2 has fault perhaps to be in the starting period of motor 9, power turbine did not provide or only provided very little power this moment.Motor passes through electrical network 8 and obtains this not enough energy the current device from ship thus 6 this moments.
Typical power turbine for example has the power of 600kW to 1300kW and 90% efficient (η power turbine ≈ 90%, η turbosupercharger ≈ 70%).Power turbine this moment is with about 30000 rev/mins rotating speed rotation, motor according to the difference (50 or 60 hertz) of electrical network with the bent axle of the rotating speed rotation of 1800 rev/mins or 1500 rev/mins and motor with 90 rev/mins of rotations.Driving mechanism 4 must correspondingly design.
8 this moments the electrical network with 50 or 60 hertz of work for example can be set as electrical network on the ship, it can provide high power arbitrarily in the power spectrum of motor, and can not disturbed (einbrechen).When the operating pressure of motor 9 under running state II increased, oil pump sucked and identical machine oil volume flow under low operating pressure at this moment, because motor 6 can obtain corresponding higher power and work with the frequency beat of electrical network from electrical network 8.When for example using reciprocating pump or gear pump as oil pump 7, oil pump is then supplied with constant machine oil volume flow.The situation that the machine oil volume flow that needs for motor descends can additionally be provided with by-pass line in motor, through it a part of flow of lubricant in the motor is drained.
Certainly under the situation that does not break away from basic design of the present invention, can realize some with shown in the different schemes of flexible program.
For example can consider to be provided with that overrunning clutch replaces controlled clutch or as it replenish, thereby throw off coupling and only when power turbine moves, mechanical output is passed to motor at power turbine and motor under the running state II.So not only mechanical output but also electric power all are used to drive oil pump.It is also conceivable that through epicyclic transmission mechanism for this reason and come the coupling power turbine, motor and oil pump device.
Be contemplated that equally, the clutch that can be continuously be transformed into running state II from running state I be set replace and have the only controlled clutch of two running statees.
