漳州東山移動(dòng)螺桿空壓機(jī)租賃空氣壓縮機(jī)噪聲源分析

Noise Source Analysis of Air Compressor
空壓機(jī)是一種噪聲較大的設(shè)備。在室外安裝時(shí)，dh90-1離心式空氣壓縮機(jī)在2m處的噪聲為114.5db (A)。
Air compressor is a kind of equipment with high noise. When installed outdoors, the noise of dh90-1 centrifugal air compressor at 2m is 114.5db (A).
空壓機(jī)噪聲包括空氣動(dòng)力噪聲、機(jī)械噪聲和電磁噪聲。輻射噪聲可分為:空壓機(jī)機(jī)體噪聲源;電機(jī)噪聲源;進(jìn)氣管噪聲源;進(jìn)氣口噪聲源;排氣管噪聲源;排氣噪聲源。采用近場法對各部件的噪聲頻譜進(jìn)行了測量，表明該空壓機(jī)的噪聲為中高頻噪聲。
The noise of air compressor includes aerodynamic noise, mechanical noise and electromagnetic noise. Radiated noise can be divided into: air compressor body noise source; motor noise source; intake pipe noise source; intake port noise source; exhaust pipe noise source; exhaust noise source. The noise spectrum of each component is measured by the near field method, which shows that the noise of the air compressor is medium and high frequency noise.
二、控制空壓機(jī)機(jī)體噪聲和電機(jī)噪聲，***合理的措施是為空壓機(jī)增設(shè)隔音罩。為確保隔音罩的降噪效果，應(yīng)注意:
2. The most reasonable measure to control the noise of the air compressor body and motor is to add a sound insulation cover for the air compressor. In order to ensure the noise reduction effect of the sound insulation cover, attention should be paid to:
1. 外殼壁數(shù)據(jù)應(yīng)具有足夠的隔聲能力。本工程采用多層隔聲結(jié)構(gòu)，設(shè)計(jì)隔聲能力為30dB (A)。
1. Shell wall data should h***e adequate sound insulation. This project adopts multi-layer sound insulation structure, and the designed sound insulation capacity is 30dB (A).

2. 門、窗、孔等隔音薄件的處理。在本工程中，門、采光窗和通風(fēng)口應(yīng)安裝消聲器。消聲器結(jié)構(gòu)的兩個(gè)設(shè)計(jì)值為25dB (A)。
2. Processing of sound-proof thin parts such as doors, windows and holes. In this project, mufflers should be installed on doors, lighting windows and ventilation outlets. The two design values of muffler structure are 25dB (A).
3.內(nèi)墻吸聲處理較強(qiáng)。本項(xiàng)目采用50mm厚離心玻璃棉氈作為吸聲數(shù)據(jù)，其高頻吸聲性能優(yōu)異，符合要求的控制噪聲頻率特性。為了增加低頻吸聲，在吸聲數(shù)據(jù)后留下50mm厚的空氣層。
3. The sound absorption treatment of the inner wall is strong. In this project, 50 mm thick centrifugal glass wool felt is used as sound absorption data. Its high frequency sound absorption performance is excellent, and it meets the requirements of controlling noise frequency characteristics. In order to increase low frequency sound absorption, 50 mm thick air layer is left after sound absorption data.
由于消費(fèi)者的需求，空壓機(jī)無法關(guān)閉。在設(shè)計(jì)中，應(yīng)用了原氣動(dòng)擰緊機(jī)的鋼筋混凝土座椅，將隔聲罩加成兩部分。由于采用了鋼筋混凝土支座的支撐，使得隔聲罩的主龍骨結(jié)構(gòu)得到簡化，便于機(jī)器運(yùn)行時(shí)的施工。隔音罩下部70%可采用磚墻，節(jié)約管理資金。為了滿足設(shè)備的維修要求，閥蓋是可拆卸的，以便于機(jī)械操作的舉升;隔聲罩下設(shè)計(jì)有聲門，便于管理人員出入和維護(hù)。
Because of the demand of c***umers, the air compressor can not be shut down. In the design, the reinforced concrete seat of the original pneumatic tightener is applied, and the sound insulation cover is added into two parts. Because of the support of reinforced concrete support, the main keel structure of the sound insulation cover is simplified, which is convenient for the c***truction of machine operation. 70% of the lower part of the sound insulation cover can use brick wall, s***ing management funds. In order to meet the maintenance requirements of the equipment, the valve cover is removable to facilitate the mechanical operation of lifting; the glottis under the sound insulation cover is designed to facilitate access and maintenance of managers.
