氣壓傳動的特點
氣壓(ya)傳動具有以(yi)下特點(dian)
1．氣壓傳動的優點
①氣動動作迅速、反應快(0．02s)，調節控制方便，維護簡單，不存在介質變質及補充等問題。②便于集中供氣和遠距離輸送控制。因空氣粘度小(約為液壓油的萬分之一)，在管內流動阻力小，壓力損失小。⑧氣動增壓泵氣(qi)(qi)動(dong)系統對工(gong)作環境(jing)適應性(xing)好(hao)。特別(bie)在易燃、易爆、多塵(chen)埃、強磁、輻射(she)、振動(dong)等惡劣工(gong)作環境(jing)中(zhong)工(gong)作時，安全(quan)可(ke)靠性(xing)優于(yu)(yu)液壓(ya)、電子和電氣(qi)(qi)系統。④因空氣(qi)(qi)具有可(ke)壓(ya)縮性(xing)，能夠實現過(guo)載保護，也(ye)便于(yu)(yu)儲(chu)氣(qi)(qi)罐儲(chu)存(cun)能量，以備急(ji)需。⑤以空氣(qi)(qi)為(wei)工(gong)作介質，易于(yu)(yu)取(qu)得，節省了購(gou)買、儲(chu)存(cun)、運輸介質的費用(yong)和麻煩：用(yong)后的空氣(qi)(qi)直接排(pai)入(ru)大(da)氣(qi)(qi)，處理方(fang)便，也(ye)不(bu)污染環境(jing)。⑥氣(qi)(qi)動(dong)元件(jian)結(jie)構(gou)簡單，成本低，壽(shou)命長，易于(yu)(yu)標準(zhun)化、系列(lie)化和通用(yong)化。⑦可(ke)以自(zi)(zi)動(dong)降溫。因排(pai)氣(qi)(qi)時氣(qi)(qi)體膨脹，溫度降低。⑧與液壓(ya)傳動(dong)一樣，操作控(kong)制方(fang)便，易于(yu)(yu)實現自(zi)(zi)動(dong)控(kong)制。
2．氣壓傳動的缺點
①運動平穩性較差。因空氣可壓縮性較大，其工作速度受外負載影響大。②工作壓力較低(0．3—1MPa)，不易獲得較大的輸出力或轉矩。⑧空氣凈化處理較復雜。氣源中的雜質及水蒸氣必須凈化處理。④因空氣粘度小，潤滑性差，因此需設潤滑氣動增壓泵裝置。⑤有(you)較大(da)的排氣噪(zao)聲。．
