2、正確選(xuan)(xuan)擇水(shui)環(huan)(huan)式真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)點(dian)。每個泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)都有一(yi)定的(de)(de)(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)(ya)(ya)(ya)力刻度(du)(du)(du)。例如(ru)，分散泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)為10-3?10-7mmHg。在如(ru)此(ci)寬(kuan)的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)力范圍(wei)內，泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)抽速隨壓(ya)(ya)(ya)(ya)力而變化。約(yue)510-6mmHg。因(yin)此(ci)，泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)點(dian)應(ying)在此(ci)范圍(wei)內選(xuan)(xuan)擇，并(bing)且不(bu)(bu)應(ying)長時間(jian)在10-8mmHg下工(gong)(gong)作(zuo)(zuo)(zuo)。另(ling)一(yi)個例子(zi)是鈦提升泵(beng)(beng)(beng)(beng)(beng)(beng)(beng)(beng)可(ke)以在10-2mmHg的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)力下工(gong)(gong)作(zuo)(zuo)(zuo)，但其工(gong)(gong)作(zuo)(zuo)(zuo)壓(ya)(ya)(ya)(ya)力應(ying)小(xiao)于(yu)110-5mmHg。 3、

羅(luo)茨真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)(zai)許多行(xing)(xing)業，例(li)如石(shi)油，化學(xue)工(gong)業和塑料(liao)中(zhong)，如果氣(qi)壓差(cha)過高(gao)，則(ze)可(ke)能(neng)會(hui)(hui)發(fa)生過載。更嚴重的(de)(de)(de)(de)問(wen)題是電(dian)(dian)機燒(shao)毀問(wen)題。下(xia)面，我將(jiang)介(jie)紹一(yi)些防(fang)止(zhi)設備過載和燃燒(shao)電(dian)(dian)動(dong)(dong)機的(de)(de)(de)(de)方(fang)法。 1、使用液(ye)力(li)偶合(he)器(qi)(qi)，液(ye)力(li)偶合(he)器(qi)(qi)還可(ke)以(yi)防(fang)止(zhi)過載 ①在(zai)(zai)正常工(gong)作條件下(xia)，在(zai)(zai)泵(beng)(beng)(beng)和電(dian)(dian)動(dong)(dong)機之(zhi)間安(an)裝了(le)液(ye)力(li)偶合(he)器(qi)(qi)，額(e)定扭(niu)矩(ju)從(cong)電(dian)(dian)動(dong)(dong)機端(duan)傳遞到泵(beng)(beng)(beng)。 ②羅(luo)茨真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)壓差(cha)由(you)液(ye)力(li)偶合(he)器(qi)(qi)傳遞的(de)(de)(de)(de)扭(niu)矩(ju)決定，而(er)其(qi)可(ke)傳遞的(de)(de)(de)(de)扭(niu)矩(ju)則(ze)由(you)其(qi)中(zhong)的(de)(de)(de)(de)液(ye)體量來(lai)調節。 ③當羅(luo)茨真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)在(zai)(zai)高(gao)壓下(xia)工(gong)作或與前級泵(beng)(beng)(beng)同(tong)時啟(qi)動(dong)(dong)時，液(ye)力(li)偶合(he)器(qi)(qi)內部會(hui)(hui)出現轉速(su)差(cha)，即打滑，僅傳遞一(yi)定的(de)(de)(de)(de)扭(niu)矩(ju)使泵(beng)(beng)(beng)減速(su)。 ④隨著抽(chou)氣(qi)的(de)(de)(de)(de)進(jin)行(xing)(xing)，氣(qi)體負荷逐漸降低(di)并逐漸加速(su)到額(e)定速(su)度。 2、使用真(zhen)(zhen)空(kong)(kong)(kong)電(dian)(dian)子元件控(kong)制(zhi)泵(beng)(beng)(beng)的(de)(de)(de)(de)入(ru)口(kou)壓力(li) ①在(zai)(zai)入(ru)口(kou)管道上安(an)裝了(le)一(yi)個壓力(li)表(biao)，例(li)如真(zhen)(zhen)空(kong)(kong)(kong)表(biao)或電(dian)(dian)接點真(zhen)(zhen)空(kong)(kong)(kong)壓力(li)表(biao)。 ②真(zhen)(zhen)空(kong)(kong)(kong)系統啟(qi)動(dong)(dong)后，當入(ru)口(kou)處的(de)(de)(de)(de)壓力(li)低(di)于給定值時，壓敏元件將(jiang)發(fa)送(song)信號并由(you)電(dian)(dian)氣(qi)控(kong)制(zhi)系統將(jiang)其(qi)打開。 ③如果羅(luo)茨真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)的(de)(de)(de)(de)入(ru)口(kou)壓力(li)高(gao)于規定值，則(ze)泵(beng)(beng)(beng)旁(pang)通閥(fa)會(hui)(hui)自動(dong)(dong)同(tong)時關閉(bi)或打開，從(cong)而(er)確保設備的(de)(de)(de)(de)可(ke)靠運行(xing)(xing)。 為了(le)防(fang)止(zhi)羅(luo)茨真(zhen)(zhen)空(kong)(kong)(kong)泵(beng)(beng)(beng)過載燒(shao)毀電(dian)(dian)動(dong)(dong)機，我們(men)可(ke)以(yi)在(zai)(zai)操作過程中(zhong)控(kong)制(zhi)開關，下(xia)班(ban)后及時關閉(bi)電(dian)(dian)源(yuan)，并進(jin)行(xing)(xing)例(li)行(xing)(xing)維(wei)護和清潔(jie)。這也是不拖延工(gong)作的(de)(de)(de)(de)好(hao)方(fang)法。
