凍(dong)干機(ji)中(zhong)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)排氣(qi)量如(ru)何確定?下(xia)面小(xiao)編帶(dai)大家了(le)解(jie)一下(xia).(一)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)抽(chou)(chou)速的(de)(de)性能(neng)指標 凍(dong)干機(ji)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)系(xi)統(tong)從(cong)大氣(qi)壓抽(chou)(chou)到(dao)10Pa的(de)(de)時(shi)(shi)間(jian)不多于30min。 (二)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)選(xuan)型(xing)原則 所(suo)選(xuan)主(zhu)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)的(de)(de)極限(xian)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)應(ying)比凍(dong)干箱要(yao)(yao)求(qiu)的(de)(de)極限(xian)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)高1~2個(ge)數量級。醫(yi)藥凍(dong)干一般要(yao)(yao)求(qiu)極限(xian)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)為1~5Pa,所(suo)選(xuan)主(zhu)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)極限(xian)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)應(ying)高于1X10-1~1X10-2Pa。旋(xuan)片泵(beng)(beng)、滑閥泵(beng)(beng)、羅茨泵(beng)(beng)、油增壓泵(beng)(beng)均(jun)可(ke)(ke)。 凍(dong)干箱的(de)(de)工作(zuo)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)度為4~4OPa,應(ying)在(zai)主(zhu)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)最佳(jia)抽(chou)(chou)速壓力(li)范圍內。 凍(dong)干機(ji)使用(yong)(yong)的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)還應(ying)可(ke)(ke)以抽(chou)(chou)除一些水蒸氣(qi),或(huo)者可(ke)(ke)適應(ying)被(bei)抽(chou)(chou)氣(qi)體夾雜(za)有(you)水蒸氣(qi)。 (三)抽(chou)(chou)氣(qi)速率的(de)(de)計(ji)算 凍(dong)干機(ji)有(you)預抽(chou)(chou)時(shi)(shi)間(jian)要(yao)(yao)求(qiu),對于冷(leng)阱(jing)和凍(dong)干箱共用(yong)(yong)一臺制冷(leng)機(ji)時(shi)(shi),這個(ge)時(shi)(shi)間(jian)要(yao)(yao)求(qiu)很(hen)重要(yao)(yao)。滿足不了(le)時(shi)(shi)可(ke)(ke)能(neng)造成預凍(dong)制品融化。如(ru)果在(zai)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)冷(leng)凝(ning)器(冷(leng)阱(jing))制冷(leng)的(de)(de)同時(shi)(shi),凍(dong)干箱還能(neng)供(gong)冷(leng)保持低(di)溫(wen),這一時(shi)(shi)間(jian)要(yao)(yao)求(qiu)就不那么重要(yao)(yao)了(le)。也就是說可(ke)(ke)以適當延長要(yao)(yao)求(qiu)的(de)(de)時(shi)(shi)間(jian),然(ran)這對凍(dong)干機(ji)的(de)(de)性能(neng)還是略有(you)影響(xiang)的(de)(de)。不同的(de)(de)行業需求(qiu)的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)度不同,所(suo)以要(yao)(yao)選(xuan)擇合適的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)(beng)去滿足生產(chan)中(zhong)需要(yao)(yao)的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)度的(de)(de)要(yao)(yao)求(qiu).
