Further, as shown in Figures 2 and 3, non-contact electric eddy position sensing mechanism 24 is made up of non-contact electric convolution position transducer 35, sensor locking nut 36, position transducer support 37, bracket lock jack panel 38, sensor sensing seat 39 and sensor sensing body 40.Sensor sensing seat 39 is fixed on high pressure oil pump 42, and sensor sensing body 40 is fixed on the control rack 41 of high pressure oil pump 42, and moves with control rack 41.
Below the negative pressure air feed Marine engine system working principle of the present embodiment is described.
When being opened by the diesel oil control switch of cockpit control cabinet 8, marine engine is at fuel feeding mode of operation, and marine engine only uses diesel oil as fuel.
When being opened by the double fuel control switch of cockpit control cabinet 8, marine engine enters air feed fuel feeding double fuel operational mode state, and explosion-proof solenoid valve 5 is opened automatically, in this condition:
When marine engine is at idling work, because suction pressure temperature transducer 18, speed probe 21 and oil temperature sensor 25 parameter do not reach setting value, explosion-proof solenoid valve 27 is still in closed condition, and fuel feeding mode of operation still pressed by marine engine.
Pull speed-regulating handle 23, when marine engine is with certain rotating speed and load operation, suction pressure temperature transducer 18, speed probe 21 and oil temperature sensor 25 parameter reach setting value, explosion-proof solenoid valve 27 is opened under engine room control cabinet 9 is ordered, and electronic throttle 16 regulates air demand under engine room control cabinet 9 is ordered simultaneously.LNG is from gas cylinder 31, through cylinder manifold 30, main gas valve 29, to empty bath formula vaporizer 1, vaporize through sky bath formula vaporizer 1, through explosion-proof solenoid valve 5, to one-level pressure relief valve 6, reduce pressure through one-level pressure relief valve 6, manually stop valve 10 again, filter 28, explosion-proof solenoid valve 27, to second depressurized valve 12, zero-pressure valve 14 is decompressed to further through second depressurized valve 12, after zero-pressure valve 14 processes (gaseous-pressure is close to barometric pressure), to electronic throttle 16, intake manifold is mixed into motor at mixer 17 place and air, Substitute For Partial diesel oil, realize air feed fuel feeding double fuel mode of operation.Because motor is under a certain rotating speed and load, it needs total fuel certain, adding now because of LNG, engine speed raises, and motor running to keep original rotating speed, just automatically reducing and entering the suitable amount of fuel of LNG gas flow, thus realizing " with gas generation oil " double fuel mode of operation.Along with engine operating condition variation, air feed fuel delivery is along with change.
Supplying oil and gas ratio-dependent is determined by engine room control cabinet 9.Particularly, engine room control cabinet 9 gathers tach signal by speed probe 21, suction pressure temperature transducer 18 gathers suction pressure temperature signal, non-contact electric eddy position sensing mechanism 24 gathers control rack position signal, these signals are as master signal, determine fuel oil, fuel gas supply ratio, namely air feed fuel delivery.Gather gaseous-pressure signal, oil temperature sensor 25 harvester oil temperature signal by gaseous-pressure transmitter 15, these signals, as auxiliary control signal, revise supplying oil and gas amount.Gather fuel gas temperature signal by fuel gas temperature transmitter 4, gaseous-pressure transmitter 7 gathers gaseous-pressure signal, and exhaust temperature sensor 19 gathers the warm signal of row, these signals are as marine engine supervisory signal, exceed its setting value, system blocks fuel gas supply automatically, returns fuel feeding mode of operation.
And the working principle between high pressure oil pump 42 and non-contact electric eddy position sensing mechanism 24 is as following: as accompanying drawing 2, ship machine control rack is in maximum fuel feeding position.Sensor sensing seat 39 is fixed on high pressure oil pump 42, and sensor sensing body 40 is fixed on control rack 41, and moves with control rack 41.As accompanying drawing 2, sensor sensing body 40 is withstood (maximum oil mass restriction site) by position transducer support 37, distance non-contact electric convolution position transducer 1 millimeter, control rack is in maximum fuel feeding position, namely ship machine is in maximum fuel feeding position, control rack 41 to subtracting the motion of oily direction, namely can only move in high pressure oil pump 42.As accompanying drawing 3, control rack is at ship machine idle position.When control rack 41 drives sensor sensing body 40 to move to ship machine idling control rack position, high pressure oil pump 42 can only provide idling oil mass.If pull speed-regulating handle 23, ship machine rotating speed rises, and control rack 41 is to the motion of non-contact electric convolution position transducer 35 direction, and sensor sensing body 40 and non-contact electric convolution position transducer 35 location gap shorten, and ship machine fuel delivery increases; If draw fuel cut-off handle 43, high pressure oil pump control rack 41 continues to move in high pressure oil pump 42, and sensor sensing body 40 is elongated with non-contact electric convolution position transducer 35 location gap, and engine oil amount reduces further, and motor will stop working.In a word, high pressure oil pump control rack 41 position and high pressure oil pump 42 fuel delivery one_to_one corresponding, i.e. control rack 41 determining positions engine oil amount.As long as so control control rack 41 position just control engine oil amount.
Other device function:
1, gas pressure gage 13 function: gas pressure force value in air feed path is provided in real time.
2, safety valve 2 function: LNG is after sky bath formula vaporizer 1 is vaporized, and when gaseous-pressure is too high, safety valve 2 is opened automatically, makes gaseous-pressure in air feed path get back in predetermined range, protection explosion-proof solenoid valve 5, one-level pressure relief valve 6.
3, suction tude explosion-proof valve 26, crankcase anti-explosion valve 22 function: protection motor.
4, Fuel Gas Leak Alarm 11, fire alarm 20 function: cabin safety installations, if reported to the police, explosion-proof solenoid valve 5 and explosion-proof solenoid valve 27 truncated system fuel gas supply automatically, marine engine returns fuel feeding mode of operation.
5, automatic stop valve 3 function: when gas burning system breaks down, automatic stop valve 3 is opened, remains combustion gas by relief opening 32, is discharged into place of safety in air feed path.
Oily characteristic is adjusted for the deficiencies in the prior art and ship machine high pressure oil pump, the utility model embodiment provides a kind of ship machine diesel oil/LNG double fuel vacuum control system, be particularly suitable for carrying out double fuel transformation to power at the ship machine of more than 200KW, be exclusively used in the transformation of ship machine gasification.Use safety, reliable, good economy performance, improve the discharge of ship machine greatly.Concrete innovative point has:
1, ship machine fuel gas supply amount is only controlled, fuel delivery is controlled voluntarily by ship machine, because ship machine is under a certain rotating speed and load, it needs total fuel certain, automatically adjust oily characteristic according to ship machine, if increase fuel gas supply amount, ship machine is in order to keep original rotating speed, the corresponding amount of fuel of automatic minimizing, otherwise its rotating speed will change.
2, remove oil mass limting mechanism, adopt non-contact electric convolution position sensing mechanism, accurate feedback ship machine is high pressure oil pump control rack position under any operating mode, i.e. fuel delivery.
3, gas leakage alarm, flame is reported to the police, bifuel system malfunction alarm directly controls ship machine fuel reburning, as long as namely have warning, the utility model blocks fuel gas supply automatically, and ship machine turns back to fuel oil service pattern simultaneously, use safety, reliable.
