　　螺桿式空壓機工作原(yuan)理是由一(yi)對相互平(ping)行嚙合(he)的(de)(de)陰陽轉子(zi)在氣(qi)(qi)缸(gang)內轉動，使轉子(zi)齒(chi)槽(cao)之間的(de)(de)空(kong)氣(qi)(qi)不(bu)斷(duan)地產生周期性的(de)(de)容積變化，空(kong)氣(qi)(qi)則沿著轉子(zi)軸線由吸入側輸送至輸出側，實現空(kong)壓(ya)機的(de)(de)吸氣(qi)(qi)、壓(ya)縮和排氣(qi)(qi)的(de)(de)全過程(cheng)。

　　空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)由(you)于在滿負荷狀態(tai)下(xia)長(chang)時(shi)(shi)間運行的(de)(de)(de)可能(neng)(neng)性(xing)(xing)，所以，用(yong)(yong)戶在選型時(shi)(shi)只能(neng)(neng)按(an)較(jiao)大(da)需(xu)求來確定電(dian)機(ji)(ji)容量(liang)，造成(cheng)空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)系(xi)統余量(liang)一(yi)般偏大(da)。傳(chuan)統空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)都(dou)采用(yong)(yong)星三角降壓(ya)(ya)(ya)啟動，但(dan)工頻啟動時(shi)(shi)電(dian)流仍然能(neng)(neng)達到額定電(dian)流的(de)(de)(de)2~3倍，沖擊大(da)，會(hui)影(ying)響到電(dian)網的(de)(de)(de)穩定性(xing)(xing)。且大(da)多(duo)數空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)是連續運行，由(you)于一(yi)般螺桿式空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)的(de)(de)(de)電(dian)機(ji)(ji)本(ben)身不能(neng)(neng)根據壓(ya)(ya)(ya)力(li)需(xu)求的(de)(de)(de)變動來實(shi)現降速，使電(dian)機(ji)(ji)輸出功率與現場實(shi)際壓(ya)(ya)(ya)力(li)需(xu)求量(liang)相匹配，導致(zhi)在用(yong)(yong)氣量(liang)少的(de)(de)(de)時(shi)(shi)候仍然要空(kong)(kong)載運行，造成(cheng)巨大(da)的(de)(de)(de)電(dian)能(neng)(neng)浪費。據統計，空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)占大(da)型工業(ye)設備(bei)(風機(ji)(ji)、水(shui)泵、鍋(guo)爐等)幾乎所有的(de)(de)(de)耗(hao)電(dian)量(liang)的(de)(de)(de)15%，空(kong)(kong)壓(ya)(ya)(ya)機(ji)(ji)的(de)(de)(de)節能(neng)(neng)改造意(yi)義重大(da)。

　　空(kong)(kong)壓機(ji)(ji)的(de)(de)(de)運(yun)行(xing)成(cheng)(cheng)主要由采購成(cheng)(cheng)本(ben)(ben)、維(wei)護成(cheng)(cheng)本(ben)(ben)和能(neng)源(yuan)成(cheng)(cheng)本(ben)(ben)組成(cheng)(cheng)，其中(zhong)能(neng)源(yuan)成(cheng)(cheng)本(ben)(ben)大(da)約(yue)占(zhan)總運(yun)行(xing)成(cheng)(cheng)本(ben)(ben)的(de)(de)(de)2/3，由此通過降(jiang)低(di)能(neng)源(yuan)成(cheng)(cheng)本(ben)(ben)30%，再加(jia)上變頻(pin)起動(dong)后對(dui)(dui)設備(bei)的(de)(de)(de)沖擊減(jian)少(shao)，維(wei)護和維(wei)修量也跟隨(sui)降(jiang)低(di)，所以(yi)將大(da)大(da)降(jiang)低(di)運(yun)行(xing)成(cheng)(cheng)本(ben)(ben)。變頻(pin)控制系統(tong)具有精(jing)確的(de)(de)(de)壓力(li)控制能(neng)力(li)，通過使螺桿式空(kong)(kong)壓機(ji)(ji)的(de)(de)(de)空(kong)(kong)氣(qi)壓力(li)輸出與用(yong)戶空(kong)(kong)氣(qi)系統(tong)所需(xu)的(de)(de)(de)氣(qi)量相匹配，可以(yi)使管網的(de)(de)(de)系統(tong)壓力(li)保持恒定(ding)，有效地提(ti)高了供(gong)氣(qi)的(de)(de)(de)質(zhi)量。變頻(pin)器有軟啟(qi)動(dong)功能(neng)，可減(jian)少(shao)起動(dong)時(shi)對(dui)(dui)壓縮(suo)機(ji)(ji)和機(ji)(ji)械部(bu)件所造成(cheng)(cheng)的(de)(de)(de)沖擊，增強系統(tong)可靠(kao)性，延(yan)長壓縮(suo)機(ji)(ji)使用(yong)壽命。同時(shi)，減(jian)少(shao)空(kong)(kong)壓機(ji)(ji)啟(qi)動(dong)對(dui)(dui)電網的(de)(de)(de)沖擊。

　　隨著螺桿式(shi)空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)在工(gong)(gong)業(ye)、礦(kuang)業(ye)、醫(yi)療業(ye)甚至農業(ye)都(dou)有日(ri)趨廣泛(fan)的(de)(de)用途，尤其在工(gong)(gong)業(ye)領(ling)域(yu)空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)的(de)(de)耗(hao)電(dian)(dian)量列居首(shou)位，絕(jue)大(da)(da)(da)部分的(de)(de)空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)都(dou)使(shi)(shi)用電(dian)(dian)動機(ji)驅動的(de)(de)方式(shi)，空(kong)(kong)(kong)(kong)(kong)氣(qi)經過(guo)濾器過(guo)濾后，進(jin)入(ru)壓(ya)(ya)(ya)縮(suo)機(ji)把空(kong)(kong)(kong)(kong)(kong)氣(qi)壓(ya)(ya)(ya)縮(suo)，壓(ya)(ya)(ya)縮(suo)空(kong)(kong)(kong)(kong)(kong)氣(qi)經過(guo)油氣(qi)分離輸出(chu)。空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)只(zhi)要(yao)處(chu)于(yu)工(gong)(gong)作狀態，電(dian)(dian)機(ji)處(chu)于(yu)額定(ding)轉(zhuan)(zhuan)速運行，由進(jin)氣(qi)閥開度的(de)(de)大(da)(da)(da)小來調節空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)(ya)機(ji)的(de)(de)輸出(chu)空(kong)(kong)(kong)(kong)(kong)氣(qi)流量大(da)(da)(da)小。即使(shi)(shi)在卸載時也以額定(ding)轉(zhuan)(zhuan)速運轉(zhuan)(zhuan)，就產(chan)生了無功能耗(hao)。因此完(wan)全有必要(yao)采取多(duo)種措施(shi)調節壓(ya)(ya)(ya)縮(suo)機(ji)出(chu)力，使(shi)(shi)電(dian)(dian)動機(ji)始終(zhong)工(gong)(gong)作在恰當(dang)負(fu)荷而節約能源。
