Abstract
An anechoic chamber installed around a large-sized motor. The anechoic chamber is square; the large-sized motor is arranged within the anechoic chamber; a wall of the anechoic chamber is composed of an inner layer and an outer layer. The inner layer, a sound-absorbent layer, is used for decreasing reverberation; the outer layer is a soundproof layer; ventilation silencers are mounted on four sides of the wall; a forced ventilation silencer is mounted on a top wall; the top wall can be opened by lifting (or direct moving), maintenance of the large-sized motor is facilitated, and a lighting window and a maintenance door are reserved. The large-sized motor is equipped with a cooling fan; an outlet of the large-sized motor is connected to the outdoor through a pipeline; another ventilation silencer is mounted at the outlet. The anechoic chamber has the advantages that noise reduction is guaranteed for the large-sized motor, motor cooling and maintenance convenience are also guaranteed, and a sound spectrum of the large-sized motor treated with the anechoic chamber is approximate to an NR (noise rating) curve.
Description
Technical field
The present invention relates to the anechoic chamber of various motors, particularly large-size machine.
Background technology
Economic develop rapidly along with China, because operating mode needs, large-size machine is widely used, the air power noise of the electromagnetic noise of motor, machinery noise and motor self-radiating wind exists and exceeds standard, only do sound insulation to motor and process traditional anechoic chamber, and the cooling fan air inlet/outlet noise of motor is not dealt with, and the whole ventilation and heat of motor, daylighting, maintenance convenience etc. are not all done to consider, noise reduction is not good, and user is dissatisfied.
Summary of the invention
The technical solution used in the present invention is: changing sound booth is sound absorption and insulation chamber (reduction reverberation), at motor radiating fan outlet, air-out muffler is installed, at four sidewalls, four ventilation mufflers are installed, wherein near motor radiating blower fan sidewall ventilation muffler, with pipeline, directly receive air inlet, the air that assurance enters motor is direct cold air from anechoic chamber, makes motor radiating best.Other heat of motor dispels the heat by the forced ventilation muffler of other three ventilating noise reductions of surveying and roof, and the sound absorption and insulation amount of all muffler sound-damping qualities and noise reduction locular wall is suitable.Four sidewalls leave observation window (light inlet window), and whole anechoic chamber leaves an access door, and convenient observation and maintenance, pushes up capable of hoisting opening (or removing), are convenient to hang out when motor needs overhaul motor.The invention has the beneficial effects as follows: the self-radiating blower fan of motor by muffler from anechoic chamber's external drum to motor cold air, make motor radiating reach maximization.Air outlet at self-radiating blower fan is provided with ventilation muffler, and all the other heats of motor dispel the heat by its excess-three platform ventilation muffler and a pressure air-out muffler.Whole anechoic chamber can not only guarantee the heat radiation maintenance of motor, can guarantee that again noise reduction is up to standard, makes the audio spectrum (outside anechoic chamber) after processing substantially meet noisc rating number, reaches desirable improvement object.

Specific embodiments: the structure of large-size machine of the present invention anechoic chamber is: do sound absorption and insulation wall 9 in the surrounding of large-size machine, this wall is divided into two layers, internal layer is absorbent treatment, increasing sound-absorbing amount is sound insulating layer with minimizing reverberation, skin, the cooling fan 4 of motor is introduced ventilation muffler 6 by pipeline 5, the air that assurance enters motor is the cold air entering from outdoor, is convenient to heat radiation.The air outlet of cooling fan 4 is connected to outdoor and ventilation muffler 8 is installed in exit with airduct 3, and all the other heats of motor distribute by the forced ventilation muffler 7 of the ventilation muffler 6 on three sidewalls 9 and roof mouth; And the sound-damping qualities of the sound absorption and insulation wall of the sound-damping qualities of 6.7.8 and anechoic chamber is suitable, sound insulation observation window (being light inlet window) 11 is installed on sidewall 9, and at sidewall 9, fan 10 sound absorption and insulation access doors is installed, be convenient to personnel's maintenance; Sound absorption and insulation roof 12 hangs out (or removing) when motor need to hang out maintenance, is convenient to motor overhaul.
Claims (5)
1. a use is in the noise abatement of large-size machine, its feature: this anechoic chamber not only can noise reduction, and can guarantee the ventilation and heat of motor, and room reverberation is little, convenient tour and maintenance.
2. according to claim 1, the feature of this noise reduction locular wall 9,12: inhale in noise reduction adopts and had both reduced room reverberation every (9,12) outward, can make again ambient noise up to standard.
3. according to claim 1, its feature: realize by its ventilation muffler (6,7,8) around by being arranged on for the ventilation and heat of motor 1, and muffler (6,7,8) sound-damping qualities is suitable with anechoic chamber's sound absorption and insulation wall sound-damping qualities.
4. according to claim 1, its feature: the self-radiating blower fan 4 of motor 1, air inlet are by pipeline 5 and ventilation muffler 6 from outdoor direct air intake, and air outlet is directly discharged to outdoor by airduct 3 and air-out muffler 8.
5. according to claim 1: its feature: sound absorption and insulation are pushed up 9 capable of hoisting opening (or removing), and observation window 11 can be maked an inspection tour, convenient tour and maintenance.
