摘 要
通過在壓縮機(jī)廠家的學(xué)習(xí)和網(wǎng)上資料結(jié)合，本次設(shè)計將簡單介紹空氣壓縮機(jī)吸氣、排氣過程的工作原理和有效減小噪音的方法。
吸氣、排氣過程是在壓縮缸里完成的。影響其吸氣或排氣量的因素有轉(zhuǎn)子直徑、轉(zhuǎn)子長度；P(壓力)、T（溫度）、海拔高度、n（轉(zhuǎn)速）、V（余隙容積）、泄漏等。前者屬于設(shè)計因素，而后者屬于運(yùn)動因素。合理的運(yùn)用這些因素可以有效的提高壓縮機(jī)的工作效率，從而提高生產(chǎn)率。
噪音是是令人討厭或干擾的聲音，在壓縮機(jī)工作的同時還會發(fā)出不同程度的噪音，影響工作人員的身心健康。有效得減小噪音事在必行。
減小噪音的主要方法有1、保機(jī)體中的所有接頭是安全的，叉車孔關(guān)閉，機(jī)組地面的基體是固封住的。2、通過管道輸送進(jìn)氣和排氣。 3、減少反射噪聲。通過以上3點(diǎn)設(shè)計和預(yù)防，進(jìn)一步減小產(chǎn)生的噪音。此外，還有不少減小噪音的途徑。通過種種減小噪音的方法，使壓縮機(jī)真正的實現(xiàn)規(guī)范化，符合國家規(guī)定的標(biāo)準(zhǔn)。
關(guān)鍵詞：壓縮機(jī)，V形帶，螺桿，噪音.
By compressor manufacturers in the study and on-line information integration, this will be designed to brief air compressor suction, exhaust the process of working principle and effective method of reducing noise.
Suction, exhaust in the compression process is completed Gang Li. Breathing or affect its emissions factors rotor diameter, the length of the rotor; P (pressure), T (temperature), altitude, n (speed), V (MS gap volume), the leakage. The former are design factors, which are factors campaign. Reasonable use of these factors can effectively improve the efficiency of the compressor, thereby improving productivity.
Yes yes noise nuisance or interfere with the voice of the compressor will be issued at the same time the work of different levels of noise and affect the physical and mental health staff. Effective in reducing noise is inevitable.
The main method of reducing noise there, in all-body joints are safe, forklift hole closed, the ground crew is solid matrix sealed. 2, piped through the intake and exhaust. 3, reducing reflection noise. Through the above 3:00 design and prevention, and further reduce the noise generated. In addition, there are many ways of reducing noise. Reduce noise through a variety of methods, to achieve real standardization compressor, in line with the state standards.
Key words: compressor, V-shaped belt, screw, noise.
