空壓機即是空氣壓縮機，是為了工廠中各個車間提供壓縮空氣的設備，通過螺桿、栓柱等機構將從外界吸入的常壓空氣予以壓縮，存貯于壓力容器中，通過管路送至各個生產車間，一些需要使用壓縮空氣的設備如清洗機的吹干工位，各種氣動量儀，設備的氣缸等，都需要壓力在0.4-1.0MPa的高壓空氣來運行，空壓機的使用就是為了制造高壓空氣的。

空(kong)壓機特征特點

由(you)電動(dong)(dong)機(ji)直(zhi)接驅(qu)動(dong)(dong)壓(ya)縮機(ji)，使曲軸產生(sheng)旋轉運動(dong)(dong)，帶動(dong)(dong)連桿使活塞產生(sheng)往復(fu)運動(dong)(dong)，引起氣(qi)(qi)(qi)缸容(rong)積變(bian)化。由(you)于(yu)(yu)氣(qi)(qi)(qi)缸內(nei)壓(ya)力的變(bian)化，通過進(jin)氣(qi)(qi)(qi)閥使空(kong)氣(qi)(qi)(qi)經(jing)過空(kong)氣(qi)(qi)(qi)濾清器(qi)（消聲器(qi)）進(jin)入(ru)氣(qi)(qi)(qi)缸，在壓(ya)縮行程中，由(you)于(yu)(yu)氣(qi)(qi)(qi)缸容(rong)積的縮小(xiao)，壓(ya)縮空(kong)氣(qi)(qi)(qi)經(jing)過排氣(qi)(qi)(qi)閥的作用，經(jing)排氣(qi)(qi)(qi)管，單(dan)向閥（止回(hui)閥）進(jin)入(ru)儲(chu)氣(qi)(qi)(qi)罐(guan)，當排氣(qi)(qi)(qi)壓(ya)力達到額定壓(ya)力0.7MPa時(shi)由(you)壓(ya)力開(kai)(kai)關(guan)控制(zhi)而自(zi)(zi)動(dong)(dong)停機(ji)。當儲(chu)氣(qi)(qi)(qi)罐(guan)壓(ya)力降至(zhi)0.5--0.6MPa時(shi)壓(ya)力開(kai)(kai)關(guan)自(zi)(zi)動(dong)(dong)聯(lian)接啟(qi)動(dong)(dong)  。

而空氣(qi)(qi)(qi)(qi)壓縮(suo)機(ji)就是(shi)(shi)提供氣(qi)(qi)(qi)(qi)源動(dong)(dong)(dong)力，是(shi)(shi)氣(qi)(qi)(qi)(qi)動(dong)(dong)(dong)系統(tong)的核心(xin)設備,機(ji)電引氣(qi)(qi)(qi)(qi)源裝置(zhi)中的主體，它是(shi)(shi)將原動(dong)(dong)(dong)（通(tong)常是(shi)(shi)電動(dong)(dong)(dong)機(ji)或柴(chai)油機(ji)）的機(ji)械能(neng)轉換成氣(qi)(qi)(qi)(qi)體壓力能(neng)的裝置(zhi)，是(shi)(shi)壓縮(suo)空氣(qi)(qi)(qi)(qi)的氣(qi)(qi)(qi)(qi)壓發(fa)生裝置(zhi)。
