Description
Technical field
This utility model relates to motor technology field, the sound insulation and noise reduction protective cover of a kind of threephase asynchronous.
Background technology
Noise on human body produces harm, and physiological directly affecting is not had high frequency noise obvious by low frequency noise, but low frequency noise can produce long-range impact to health.Low frequency noise is different from high frequency noise, and it is not easy decay, along with distance is the most remote or meets with barrier, can decay rapidly, and low frequency noise successively decreases the slowest, and sound wave is the longest, can pass through barrier, distance long-range raid and transmural through walls easily and directly enter human ear.It is 20～200Hz that China orders for the audio frequency range of low frequency noise, and frequency is intermediate frequency at 500Hz～2kHz, and frequency is high frequency at 2kHz～16kHz.
Improvement high and low frequency noise is one of recognized problem of noise abatement, especially when threephase asynchronous works, threephase asynchronous structure makes mechanical movement and can produce a large amount of noise, continual noise causes production environment extremely severe, works the most in the environment and can make the impaired hearing of people.The most commonly used Sound-proof material or cotton the sealing by threephase asynchronous of complex sound insulation alleviate noise at present, but threephase asynchronous work can produce the noise of multi-frequency, and the loudness of each frequency noise is different, but existing sound insulation and noise reduction measure is the most single, it is impossible to effectively reduce the noise that spectrum structure is complicated.
Conventional hood is that a metal sheet makes, and this hood can only play rainproof and protective effect, does not has sound-deadening and noise-reducing effect；The noise of electromotor is up to more than 86dB; for the workmen around mobile welding workshop; it is operated in all day in relatively high noise environments; easily mood is irritated, tired; attention when if things go on like this will affect work and healthy, it is therefore desirable to a kind of sound insulation and noise reduction is effective and does not affect the threephase asynchronous protective cover of heat radiation with satisfied use demand.
Utility model content
The purpose of this utility model is to provide the sound insulation and noise reduction protective cover of a kind of threephase asynchronous, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of sound insulation and noise reduction protective cover of threephase asynchronous; including motor cover body, radiating fin, Sound-proof material layer and acoustical cotton layer; described engine casing (Eng Cas) external body is provided with some radiating fins; motor cover body bottom welding has leg; it is disposed with Sound-proof material layer, cellular board, acoustical cotton layer and perforated panel from outer layer to internal layer on wall in engine casing (Eng Cas) body; Sound-proof material layer is pasted onto the outside of cellular board; Sound-proof material layer is fixed in engine casing (Eng Cas) body on wall; cellular board medial surface is fixed with perforated panel, is filled with acoustical cotton layer between perforated panel and cellular board.
As further program of the utility model: described motor cover body is the hollow circular cylinder structure that thin metal foil is made.
As further program of the utility model: described outside of foot is welded with reinforcing plate.
