SMC電氣(qi)比例閥特點：

1）可(ke)實現壓(ya)力(li)、速(su)度的無極調節，避免了(le)常通的開關式氣閥換(huan)向(xiang)時的沖擊(ji)現象。

2）能(neng)實現遠程控制和(he)程序(xu)控制。

3）與(yu)斷續(xu)控制相比，系統簡化，元件大大減(jian)少。

4）與液壓比例閥相(xiang)比，體積小、重量輕、結構簡(jian)單、成本較低，但響應速度比液壓系(xi)統慢得多，對負載變化也(ye)比較敏感。

5）使用功(gong)率(lv)小、發熱少、噪聲(sheng)低。

6）不會發(fa)生火災(zai)，不污染環境。受溫度變化的影響小。

SMC電氣比例閥使用注意事項：

1、SMC電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)之前,應(ying)設置(zhi)5μm以下過(guo)濾精度和油霧(wu)分離器，保證氣源(yuan)處理系(xi)(xi)統達到SMC壓(ya)(ya)(ya)(ya)(ya)縮(suo)空氣清凈(jing)化(hua)系(xi)(xi)統第④系(xi)(xi)列的(de)要(yao)求，向ITV比例(li)閥(fa)(fa)提(ti)供清潔干燥的(de)壓(ya)(ya)(ya)(ya)(ya)縮(suo)空氣,以便能(neng)(neng)達到ITV電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)應(ying)有的(de)各(ge)種特性。2、SMC電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)之前,不得(de)裝油霧(wu)器。3、SMC電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)在(zai)加壓(ya)(ya)(ya)(ya)(ya)狀(zhuang)態(tai)下切(qie)斷(duan)電(dian)(dian)(dian)(dian)(dian)源(yuan),出(chu)口(kou)側(ce)(ce)壓(ya)(ya)(ya)(ya)(ya)力(li)能(neng)(neng)暫(zan)時(shi)保持(chi)(chi)，但不能(neng)(neng)一(yi)直(zhi)保持(chi)(chi)。4、SMC電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)在(zai)控制狀(zhuang)態(tai),由于停電(dian)(dian)(dian)(dian)(dian)等失去電(dian)(dian)(dian)(dian)(dian)源(yuan),出(chu)口(kou)側(ce)(ce)壓(ya)(ya)(ya)(ya)(ya)力(li)可保持(chi)(chi)一(yi)次，另外讓(rang)出(chu)口(kou)側(ce)(ce)向大氣開放時(shi)，壓(ya)(ya)(ya)(ya)(ya)力(li)會(hui)不斷(duan)下降直(zhi)至大氣壓(ya)(ya)(ya)(ya)(ya)力(li)。5、SMC電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)通(tong)電(dian)(dian)(dian)(dian)(dian)后，若切(qie)斷(duan)供給壓(ya)(ya)(ya)(ya)(ya)力(li),電(dian)(dian)(dian)(dian)(dian)磁閥(fa)(fa)仍動作(zuo)，會(hui)產生蜂鳴(ming)聲而降低壽命，故切(qie)斷(duan)氣源(yuan)時(shi)一(yi)定要(yao)切(qie)斷(duan)電(dian)(dian)(dian)(dian)(dian)源(yuan)。6、SMCITV2000/ITV3000電(dian)(dian)(dian)(dian)(dian)氣比例(li)閥(fa)(fa)出(chu)口(kou)側(ce)(ce)會(hui)有0.005MPa以下的(de)殘壓(ya)(ya)(ya)(ya)(ya),要(yao)想*降至0，出(chu)口(kou)應(ying)裝三(san)通(tong)閥(fa)(fa)排放殘壓(ya)(ya)(ya)(ya)(ya)。
