正確的選擇真空泵需要注意的事項
1、真空(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)(ya)強(qiang)應該滿足真空(kong)(kong)(kong)(kong)(kong)設備的(de)(de)極限(xian)真空(kong)(kong)(kong)(kong)(kong)及工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)(ya)強(qiang)要(yao)求。如：某真空(kong)(kong)(kong)(kong)(kong)干(gan)燥工(gong)(gong)(gong)(gong)(gong)藝要(yao)求10mmHg的(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)真空(kong)(kong)(kong)(kong)(kong)度(du)，選(xuan)(xuan)用的(de)(de)真空(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)極限(xian)真空(kong)(kong)(kong)(kong)(kong)度(du)至少要(yao)2mmHg，最好能達到1mmHg。通常選(xuan)(xuan)擇泵(beng)的(de)(de)極限(xian)真空(kong)(kong)(kong)(kong)(kong)度(du)要(yao)高于(yu)真空(kong)(kong)(kong)(kong)(kong)設備工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)真空(kong)(kong)(kong)(kong)(kong)度(du)半個(ge)到一個(ge)數量(liang)級。 2、正(zheng)確地選(xuan)(xuan)擇真空(kong)(kong)(kong)(kong)(kong)泵(beng)的(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)點。每種泵(beng)都有一定的(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)(ya)強(qiang)范圍，如：2BV系(xi)列水環真空(kong)(kong)(kong)(kong)(kong)泵(beng)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)(ya)強(qiang)范圍760mmHg~25mmHg（絕壓(ya)(ya)），在這(zhe)樣寬壓(ya)(ya)強(qiang)范圍內，泵(beng)的(de)(de)抽(chou)速(su)隨(sui)壓(ya)(ya)強(qiang)而變化（詳細(xi)變化情況(kuang)參照泵(beng)的(de)(de)性能曲(qu)線），其穩定的(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)壓(ya)(ya)強(qiang)范圍為760~
