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(ya)機特(te)征(zheng)特(te)點

由(you)電動(dong)(dong)(dong)機直(zhi)接驅(qu)動(dong)(dong)(dong)壓(ya)(ya)(ya)(ya)縮機，使(shi)曲(qu)軸產生旋轉(zhuan)運動(dong)(dong)(dong)，帶動(dong)(dong)(dong)連桿使(shi)活塞產生往復運動(dong)(dong)(dong)，引起氣(qi)(qi)(qi)缸(gang)容(rong)積(ji)變(bian)化。由(you)于氣(qi)(qi)(qi)缸(gang)內壓(ya)(ya)(ya)(ya)力(li)(li)(li)的變(bian)化，通(tong)過(guo)進氣(qi)(qi)(qi)閥使(shi)空(kong)氣(qi)(qi)(qi)經(jing)(jing)過(guo)空(kong)氣(qi)(qi)(qi)濾清器（消聲器）進入氣(qi)(qi)(qi)缸(gang)，在壓(ya)(ya)(ya)(ya)縮行程中，由(you)于氣(qi)(qi)(qi)缸(gang)容(rong)積(ji)的縮小，壓(ya)(ya)(ya)(ya)縮空(kong)氣(qi)(qi)(qi)經(jing)(jing)過(guo)排氣(qi)(qi)(qi)閥的作(zuo)用(yong)，經(jing)(jing)排氣(qi)(qi)(qi)管，單向閥（止回閥）進入儲氣(qi)(qi)(qi)罐，當排氣(qi)(qi)(qi)壓(ya)(ya)(ya)(ya)力(li)(li)(li)達到額定壓(ya)(ya)(ya)(ya)力(li)(li)(li)0.7MPa時由(you)壓(ya)(ya)(ya)(ya)力(li)(li)(li)開(kai)關(guan)控制而自(zi)動(dong)(dong)(dong)停機。當儲氣(qi)(qi)(qi)罐壓(ya)(ya)(ya)(ya)力(li)(li)(li)降至0.5--0.6MPa時壓(ya)(ya)(ya)(ya)力(li)(li)(li)開(kai)關(guan)自(zi)動(dong)(dong)(dong)聯接啟動(dong)(dong)(dong)  。
