Abstract
The invention discloses a silent diesel generator set which comprises a diesel engine, a generator, a silent outer cover and a set chassis. The diesel engine, the generator and the silent outer cover are fixed to the set chassis. The silent outer cover is arranged outside the diesel engine and the generator. Compared with the prior art, specific noise reduction measures are adopted for different noise sources of the set, environment noise is reduced, the radiating structure of the diesel generator set is improved, and the noise reduction and radiation of the diesel generator set are effectively balanced.
Description
Technical field
The present invention relates to a kind of noise-reduced diesel generator group.
Background technique
Diesel generating set is a kind of is fuel with diesel oil, take diesel engine as the small power generation equipment of prime mover drive electrical generators generating.Unit is generally made up of parts such as diesel engine, generator, control box, fuel tank, storage battery, protective gears.
Diesel generating set operationally, can produce the noise of more than 100db usually.Noise is primarily of the formation such as exhaust sound, combustion noise or mechanical noise, fan noise, induction noise.Because unit operation can cause serious noise infringement to surrounding environment, in order to protect and environmental protect quality, must control equipment acoustic noise.Therefore, must consider to increase noise reduction measure in generator mechanism when designing diesel generating set.
At present, the method solving diesel generating set noise problem mostly increases traditional noise elimination, sound-absorbing structure in diesel generating set.Although this conventional construction can play a role to reduction equipment acoustic noise, this structure exchanges discharge noise reduction for sacrifice unit inner ventilation amount.This makes the heat dispersion of diesel generating set be affected, and then causes power of the assembling unit loss larger.
How to design the diesel generating set structure that simultaneously can meet ambient noise emission standard and heat dispersion and become current line important topic in the industry.
Summary of the invention
Goal of the invention: for above-mentioned existing Problems existing, the invention provides a kind of noise-reduced diesel generator group.
Technological scheme: in order to realize foregoing invention object, the invention provides a kind of noise-reduced diesel generator group, comprises diesel engine, generator, quiet outer cover and unit chassis.Diesel engine and generator are all fixed on unit chassis, and are isolated by quiet outer cover and external environment condition.
As preferably, Rubber shock-absorbing pad has been installed in diesel engine and unit chassis joint, decreases the vibrating noise produced in unit working procedure.
As preferably, described diesel engine is provided with exhaust mute cover.Be provided with unit main fan in diesel engine end, it adopts axial flow air draft structure, can produce larger air mass flow within the unit time in unit inside.
As preferably, described generator is provided with the centrifugal fan with higher blast.Consider if discharged by generator hot air downwards, because generator air gap is less, windage is comparatively large, and this partial heat cannot can be discharged more greatly because of windage by unit fan completely, then can affect the heat dissipation potential of whole unit.
As preferably, the heat radiation air outlet that generator end covers all upwards, is convenient to unit heat and is discharged.
As preferably, described quiet enclosure design has intake grill and exhaust outlet.Mute cover rear wall is provided with the main air inlet of unit, sidewall is respectively equipped with auxiliary air inlet mouth and exhaust outlet.The position of exhaust outlet is in the side of motor.The inwall of exhaust outlet and mute cover is provided with puigging.
Beneficial effect: compared with prior art, the present invention has the following advantages: adopt noise reduction measure targetedly to the different noise source of unit, reduce ambient noise.Improve diesel generating set internal heat dissipation structures, the quiet and heat radiation contradiction of active balance diesel generating set.
Accompanying drawing explanation
Fig. 1 is noise-reduced diesel generator group structural principle schematic diagram of the present invention.
Wherein, diesel engine 1, generator 2, quiet outer cover 3, unit chassis 4, exhaust mute cover 5, unit main fan 6, Rubber shock-absorbing pad 7, centrifugal fan 8, heat radiation air outlet 9, main air inlet 11, auxiliary air inlet mouth 12, exhaust outlet 13, fuel tank 14.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
Invention working principle as shown in Figure 1.Noise-reduced diesel generator group of the present invention forms primarily of following components: diesel engine 1, generator 2, quiet outer cover 3, unit chassis 4.Machine diesel engine 1 and generator 2 are all fixed on unit chassis 4, and are isolated with external environment condition by quiet outer cover 3.Unit inside comprises 2 intake grills, 1 exhaust outlet, 2 fans.In unit working procedure, produce air-flow by fan, cool air is sucked by intake grill.The air sucked is taken away internal heat and is discharged from exhaust outlet, reaches radiating effect.For meeting the quiet and heat dispersion of unit simultaneously, the present invention designs respectively to each chief component structure of unit, and specific design is as follows:
The structural design of diesel engine 1: diesel engine is provided with exhaust mute cover 5.Be provided with unit main fan 6 in diesel engine end, it adopts axial flow air draft structure, can produce larger air mass flow within the unit time in unit inside.For reducing the vibrating noise produced in diesel engine working procedure, diesel engine 1 has installed Rubber shock-absorbing pad 7 with the joint of unit chassis 4.
The structural design of generator 2: the generator of unit is provided with the centrifugal fan 8 with higher blast.Consider if discharged by the hot air of generator 2 downwards, this partial heat cannot can be discharged more greatly because of windage by centrifugal fan 8 completely, then can affect the heat dissipation potential of whole unit.As preferably, the heat radiation air outlet 9 on the end cap of generator 2 all upwards, is convenient to unit heat and is discharged.For reducing the vibrating noise produced in generator 2 working procedure, Rubber shock-absorbing pad 7 has been installed in generator and joint, chassis.
The structural design of quiet outer cover 3: the quiet enclosure design of whole diesel generating set has 2 intake grills and 1 exhaust outlet.The rear wall of quiet outer cover 3 is provided with unit main air inlet 11, two sidewalls of quiet outer cover 3 are respectively equipped with auxiliary air inlet mouth 12 and exhaust outlet 13.The position of exhaust outlet 13 is corresponding with the position of motor 1, and the inwall of exhaust outlet 13 and quiet outer cover 3 is provided with puigging.
The structural design of unit chassis 4: unit chassis 4 is provided with fuel tank 14.
The above is only the preferred embodiment of the present invention; these embodiments should be understood only for illustration of the present invention; instead of limit the scope of the invention; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
