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。

空壓(ya)機特征特點

由(you)(you)電(dian)動(dong)(dong)(dong)(dong)(dong)機(ji)直接(jie)驅動(dong)(dong)(dong)(dong)(dong)壓(ya)(ya)(ya)縮(suo)機(ji)，使(shi)曲軸(zhou)產生(sheng)旋轉運動(dong)(dong)(dong)(dong)(dong)，帶動(dong)(dong)(dong)(dong)(dong)連桿使(shi)活塞產生(sheng)往復運動(dong)(dong)(dong)(dong)(dong)，引(yin)起氣(qi)(qi)缸(gang)容積變化(hua)。由(you)(you)于(yu)氣(qi)(qi)缸(gang)內壓(ya)(ya)(ya)力的變化(hua)，通過(guo)進氣(qi)(qi)閥(fa)(fa)(fa)使(shi)空(kong)氣(qi)(qi)經(jing)過(guo)空(kong)氣(qi)(qi)濾清器(qi)（消(xiao)聲器(qi)）進入氣(qi)(qi)缸(gang)，在壓(ya)(ya)(ya)縮(suo)行(xing)程中，由(you)(you)于(yu)氣(qi)(qi)缸(gang)容積的縮(suo)小，壓(ya)(ya)(ya)縮(suo)空(kong)氣(qi)(qi)經(jing)過(guo)排氣(qi)(qi)閥(fa)(fa)(fa)的作用，經(jing)排氣(qi)(qi)管，單向閥(fa)(fa)(fa)（止回閥(fa)(fa)(fa)）進入儲(chu)氣(qi)(qi)罐，當排氣(qi)(qi)壓(ya)(ya)(ya)力達到額定(ding)壓(ya)(ya)(ya)力0.7MPa時由(you)(you)壓(ya)(ya)(ya)力開關控制而自動(dong)(dong)(dong)(dong)(dong)停機(ji)。當儲(chu)氣(qi)(qi)罐壓(ya)(ya)(ya)力降至0.5--0.6MPa時壓(ya)(ya)(ya)力開關自動(dong)(dong)(dong)(dong)(dong)聯接(jie)啟動(dong)(dong)(dong)(dong)(dong)  。

而(er)空(kong)氣(qi)(qi)(qi)(qi)壓(ya)縮機就是(shi)(shi)提供氣(qi)(qi)(qi)(qi)源(yuan)動力，是(shi)(shi)氣(qi)(qi)(qi)(qi)動系統(tong)的核心(xin)設(she)備,機電引氣(qi)(qi)(qi)(qi)源(yuan)裝置中(zhong)的主體(ti)，它是(shi)(shi)將原動（通(tong)常是(shi)(shi)電動機或(huo)柴油(you)機）的機械能(neng)轉換成氣(qi)(qi)(qi)(qi)體(ti)壓(ya)力能(neng)的裝置，是(shi)(shi)壓(ya)縮空(kong)氣(qi)(qi)(qi)(qi)的氣(qi)(qi)(qi)(qi)壓(ya)發生裝置。
