螺(luo)桿式空(kong)(kong)壓(ya)(ya)機取代(dai)易損件多(duo)、可靠性差的活塞式空(kong)(kong)壓(ya)(ya)機，已經成為必(bi)然(ran)趨勢(shi)。目前西方(fang)發達國(guo)家(jia)螺(luo)桿空(kong)(kong)壓(ya)(ya)機*為80%，并(bing)持續保持上升勢(shi)。
        空壓機系統傳統的控制方式(shi)一(yi)般由(you)電機運(yun)行控制和加卸載(zai)(zai)供氣(qi)(qi)控制方式組成。電機運(yun)行控制依(yi)靠接觸(chu)器和斷(duan)開和吸(xi)合來實現。加、卸載(zai)(zai)供氣(qi)(qi)控制方式為(wei)進氣(qi)(qi)閥(fa)開關控制方式，即壓(ya)(ya)力(li)達到上*關閥(fa)，壓(ya)(ya)縮機空載(zai)(zai)運(yun)行；壓(ya)(ya)力(li)抵達下*開閥(fa)，壓(ya)(ya)縮機加載(zai)(zai)運(yun)行。空氣(qi)(qi)壓(ya)(ya)縮機的排氣(qi)(qi)量和壓(ya)(ya)力(li)，在運(yun)轉中是不斷(duan)變化的，常因工(gong)況變

化導致用(yong)氣量變化，所以空(kong)(kong)氣壓縮機工作時(shi)總是在重復滿載－卸(xie)荷(he)工作方式。滿載時(shi)的工作電(dian)(dian)流接近電(dian)(dian)動(dong)機的額定電(dian)(dian)流，卸(xie)荷(he)時(shi)的空(kong)(kong)轉電(dian)(dian)流約為30-50％電(dian)(dian)動(dong)機額定電(dian)(dian)流。
這樣的工作方式(shi)必然產生(sheng)出諸多(duo)弊端，如(ru)：
1，起動電(dian)流(liu)很大(da)，對電(dian)網的(de)穩定及(ji)其它用(yong)電(dian)設備(bei)的(de)產生巨大(da)的(de)沖擊(ji)；
2，電(dian)動機及(ji)壓(ya)縮機經常的(de)啟停(ting)，對(dui)于機械部(bu)件和(he)氣路及(ji)元器件沖(chong)擊很大，增加空壓(ya)機和(he)供氣系統(tong)的(de)維護工作(zuo)和(he)成本，同時影響(xiang)系統(tong)的(de)使(shi)用(yong)壽(shou)命；
3，經(jing)常(chang)卸(xie)載和加載的方法來調(diao)節.這樣使整個氣網壓力經(jing)常(chang)變化,不(bu)能保(bao)持恒(heng)定的供氣壓力，在一定程度(du)上間接(jie)的影響(xiang)了產(chan)品生產(chan)質量；
