Detailed description of the invention
In order to preferably technical scheme be understood, below by being embodied as case and combining accompanying drawing and be described in detail:
The super-silent power supply of bilayer of the present invention passes through a super-silent case of bilayer, make into, air draft by the air channel extension noise reduction layer connection external world, because the entering of this double-deck super-silent case, air draft path are longer than common silencing case, so improving the amplitude of noise Natural Attenuation, greatly reduce the noise into, air draft to reveal, and use damping, absorb sound, insulate against sound and the technological means such as noise elimination, limit vibrations and sonic propagation of making an uproar；It addition, use muffler that engine exhaust is carried out noise reduction process, it is ensured that under conditions of meeting diesel generating set cooling channel and exhaust back pressure allowable, on the premise of i.e. ensureing the output of unit full power, reach super-silent working effect.
As depicted in figs. 1 and 2, the super-silent power supply of bilayer of the present invention, including double-deck super-silent case 16, exhausting silencer system 18, chassis 14, Diesel engine 23, electromotor 22, overall-in-one control schema switch cubicle 28, enters air draft dividing plate 25, wherein:
Diesel engine 23, electromotor 22, overall-in-one control schema switch cubicle 28 and exhausting silencer system 18 are fixed in dynamic Control output layer 21; this overall-in-one control schema switch cubicle 28 is control system and the electric power output system synthesis of diesel generating set; including starting, protect, various functions and the unit electric power output main switch such as communication, electric power output main switch is to connect unit and the intermediate node of load.
Double-deck super-silent case 16 surrounding inwall and top board and enter the most all to be equipped with on air draft dividing plate 25 sound-absorbing material (zinc-plated punching steel plate can be increased if desired).Open structure within sound-absorbing material is just as countless sound pistons, and when noise is through sound-absorbing material, as promoting, piston movement is the same, and sound wave causes the vibrations of the air in sound-absorbing material hole and fiber fines.Due to friction and viscosity resistance, the kinetic energy a part of noise energy being become sound piston consumes, thus decreases the outside propagation of a part of noise.
Air inlet 3 and exhaust outlet 6 are positioned at extension noise reduction layer 20 both sides, air channel, and are separated by entering air draft dividing plate 25, air channel extends noise reduction layer 20 and is divided into air intake passage 27 and air exhaust passage 26；Air intake passage 27 connects the rear end of dynamic Control output layer 21, and air exhaust passage 26 connects the front end of dynamic Control output layer 21, is formed into air draft loop.Combustion air and heat radiation air that double-deck super-silent power supply is required when running are entered air intake passage 27 by air inlet 3 and arrive the rear end of dynamic Control output layer 21；Enter air exhaust passage 26 after the heat that heat radiation air absorbs electromotor 23 and cooling water tank to be discharged to external environment from exhaust outlet 6 from dynamic Control output layer 21 front end, because this double-deck super-silent case 16 enters, air draft path is longer than common silencing case, so improving the amplitude of noise Natural Attenuation, greatly reducing the noise into, air draft and revealing.Air draft chamber up and down equipped with deflector 19 ensure unit enter, air draft smooth and easy.
All having hanger 15 and sling 17 before and after all having climbing cat ladder 2, top before and after double-deck super-silent case both sides, there is maintenance door 4 casing both sides, observes door 1, and end face has external scram button 5.To ensure that power supply lifts, safeguards, overhauls and easy to control.
High-pressure oil pipe is passed through to Diesel engine 23 fuel feeding built with double-deck anti-leak chassis fuel tank 24, chassis fuel tank 24 in chassis 14；Have forklift groove 7 bottom chassis 14, dilatory hole 9 can pitch with guarantee power supply, can pull, and side has outside fuel filler 8, fuel emission mouth 13, machine oil floss hole 12 and coolant drain mouth 11, and end bottom has sewage draining exit 10, to ensure that power-source maintenance is convenient.
The super-silent power supply of bilayer of the present invention passes through a super-silent case of bilayer, make into, air draft by the air channel extension noise reduction layer connection external world, because the entering of this double-deck super-silent case, air draft path are longer than common silencing case, so improving the amplitude of noise Natural Attenuation, greatly reduce the noise into, air draft to reveal, and use damping, absorb sound, insulate against sound and the technological means such as noise elimination, limit vibrations and sonic propagation of making an uproar；It addition, use muffler that engine exhaust is carried out noise reduction process, it is ensured that under conditions of meeting diesel generating set cooling channel and exhaust back pressure allowable, on the premise of i.e. ensureing the output of unit full power, reach super-silent working effect.
Those skilled in the art will be appreciated that, above case study on implementation is intended merely to the present invention is described, and it is not used as limitation of the invention, as long as in the spirit of the present invention, change, the modification of above-mentioned case study on implementation all will be fallen in the range of claims of the present invention.
