空(kong)(kong)氣(qi)壓(ya)(ya)縮(suo)(suo)機(ji)是一種用(yong)以壓(ya)(ya)縮(suo)(suo)氣(qi)體的(de)設備。空(kong)(kong)氣(qi)壓(ya)(ya)縮(suo)(suo)機(ji)與水泵構造類似。大多數空(kong)(kong)氣(qi)壓(ya)(ya)縮(suo)(suo)機(ji)是往(wang)復活(huo)(huo)塞式(shi)，無(wu)油空(kong)(kong)壓(ya)(ya)機(ji)，旋(xuan)轉葉(xie)片或旋(xuan)轉螺桿(gan)。空(kong)(kong)壓(ya)(ya)機(ji)應安裝在周圍環(huan)境清(qing)涼、空(kong)(kong)氣(qi)濕(shi)度低、灰塵(chen)(chen)少的(de)地(di)方(fang)。若(ruo)沒有條件(jian)，則(ze)要通過(guo)導管盡可能從清(qing)涼少塵(chen)(chen)的(de)地(di)方(fang)盡可能降低空(kong)(kong)氣(qi)的(de)濕(shi)度。容(rong)積(ji)式(shi)壓(ya)(ya)縮(suo)(suo)機(ji)，無(wu)油螺桿(gan)空(kong)(kong)壓(ya)(ya)機(ji)廠家，直接依靠改變(bian)氣(qi)體容(rong)積(ji)來提高(gao)氣(qi)體壓(ya)(ya)力(li)的(de)壓(ya)(ya)縮(suo)(suo)機(ji)。活(huo)(huo)塞式(shi)壓(ya)(ya)縮(suo)(suo)機(ji)——是容(rong)積(ji)式(shi)壓(ya)(ya)縮(suo)(suo)機(ji)，其壓(ya)(ya)縮(suo)(suo)元件(jian)是一個(ge)活(huo)(huo)塞，在氣(qi)缸(gang)內做往(wang)復運動。

空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)應安裝在周(zhou)(zhou)圍環境清涼(liang)、空(kong)(kong)(kong)(kong)(kong)氣濕(shi)度(du)(du)低、灰塵少的(de)(de)地(di)(di)方。若沒(mei)有(you)條件，則(ze)要通過導管盡可能(neng)從清涼(liang)少塵的(de)(de)地(di)(di)方盡可能(neng)降低空(kong)(kong)(kong)(kong)(kong)氣的(de)(de)濕(shi)度(du)(du)。新購置的(de)(de)空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)首運行500小(xiao)時(shi)(shi)須更換(huan)新油(you)(you)，以后按正常(chang)換(huan)油(you)(you)周(zhou)(zhou)期每(mei)2000小(xiao)時(shi)(shi)更換(huan)一(yi)次，年運行不足2000小(xiao)時(shi)(shi)的(de)(de)空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)應每(mei)年更換(huan)一(yi)次。空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)機(ji)組宜單排布(bu)置，無油(you)(you)螺(luo)桿空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)，其周(zhou)(zhou)圍須保留(liu)足以讓(rang)另部(bu)件進出的(de)(de)空(kong)(kong)(kong)(kong)(kong)間(jian)，空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)四周(zhou)(zhou)離墻至少1.5米(mi)以上(shang)；空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)離頂(ding)端空(kong)(kong)(kong)(kong)(kong)間(jian)距(ju)離2米(mi)以上(shang)。

排氣量(liang)的(de)降(jiang)(jiang)低(di)與缺油有著直接的(de)關系(xi)。一次(ci)我們在生產(chan)中(zhong)，空(kong)(kong)(kong)壓(ya)機(ji)(ji)就出(chu)現了排氣量(liang)降(jiang)(jiang)低(di)的(de)故障(zhang)，不僅(jin)不能使印刷機(ji)(ji)的(de)壓(ya)輥升降(jiang)(jiang)，而且伴有一定的(de)敲缸聲。新購置的(de)空(kong)(kong)(kong)壓(ya)機(ji)(ji)首運行(xing)500小(xiao)時須更(geng)換(huan)新油，以后(hou)按正常換(huan)油周期每2000小(xiao)時更(geng)換(huan)一次(ci)，供應無油空(kong)(kong)(kong)壓(ya)機(ji)(ji)，年(nian)運行(xing)不足2000小(xiao)時的(de)空(kong)(kong)(kong)壓(ya)機(ji)(ji)應每年(nian)更(geng)換(huan)一次(ci)。改善空(kong)(kong)(kong)壓(ya)機(ji)(ji)房(fang)內(nei)的(de)通風系(xi)統，如增加排風扇，導風管(guan)，將空(kong)(kong)(kong)壓(ya)機(ji)(ji)所產(chan)生的(de)熱風導出(chu)空(kong)(kong)(kong)壓(ya)機(ji)(ji)房(fang)使空(kong)(kong)(kong)壓(ya)機(ji)(ji)房(fang)溫度(du)下降(jiang)(jiang)，從而降(jiang)(jiang)低(di)空(kong)(kong)(kong)壓(ya)機(ji)(ji)排氣溫度(du)。
