Rexroth力士樂溢流閥A4VG250HD1D1/32LNZD10F001S節(jié)流閥單向閥 一般的電熱(鼓風)干燥箱均設(shè)有溫度均勻度參數(shù)：自然對流式的干燥箱為工作溫度上限乘3%，強制對流式的干燥箱為工作溫度上限乘2.5%。惟獨電熱真空干燥箱不設(shè)溫度均勻度參數(shù)，這是為什么？真空干燥箱內(nèi)依靠氣體分子運動使工作室溫度達到均勻的可能性幾乎已經(jīng)沒有了。從概念上我們就不能再把通常電熱(鼓風)干燥箱所規(guī)定的溫度均勻度定義用到真空干燥箱上來。在真空狀態(tài)下設(shè)這個指標也是沒有意義的。熱輻射的量與距離的平方成反比。 [B]第二，從真空設(shè)備的工作真空度來選擇真空度測控范圍：[/B]而不是根據(jù)使用真空泵或機組的極限真空度來選擇，如，系統(tǒng)采用2x旋片泵，其極限真空度可達.5Pa，由于抽氣效率的原因，往往用在1Pa以上，所以應該選擇.1kPa測量下限即可（下限越低，往往精度要求越高，價格也越高）[B]第三，合理選擇測量精度等級和測量分辨率，一般設(shè)備選擇1.級、.5級就可以了[/B]，但是如果是作為精密真空度測量和控制、計量標準器等等，就要選擇.1級、高分辨率的儀表；陶瓷薄膜規(guī)（--PS51--ABCD）;[B]對于用來測量管道、容器、散熱器、空調(diào)冰箱部件密封[/B]等等用途的真空計選型，可以選擇..25級精度、但是分辨率為1Pa的高分辨率的儀表如（28--31ap型），性價比極高；另外，還要根據(jù)需要測控的泵閥來[B]選擇儀器的測控繼電器等等控制功能[/B]，好要選擇帶有真空智能測控功能的儀表[B]（一個繼電器就能控制一個啟停或開閉的真空度區(qū)間[/B]，而不是一個點）。 一般來講，系統(tǒng)的極限真空度比系統(tǒng)的工作真空度低2%，比前級泵的極限真空度低5%。被抽氣體種類與抽氣量?檢查確定工藝要求的抽氣種類與抽氣量。因為如果被抽氣體種類與泵內(nèi)液體發(fā)生反應，泵系統(tǒng)將被污染。同時必須考慮確定合適的排氣時間與抽氣過程中產(chǎn)生的氣體量。真空容積檢查確定達到要求的真空度所需要的時間、真空管道的流阻與泄漏？紤]達到要求真空度后在一定工藝要求條件下維持真空需要的抽氣速率。選用真空泵時需要注意事項：真空泵的工作壓強應該滿足真空設(shè)備的極限真空及工作壓強要求。 2帶塵煙氣煙氣帶塵可能對受熱面產(chǎn)生磨損，又可能產(chǎn)生積灰，以至于堵灰、搭橋等現(xiàn)象。往往這兩種機理相反的現(xiàn)象又可能同時存在于一臺鍋爐之中。使用這種煙氣余熱鍋爐的選型應以防止受熱面磨損和煙道積灰、堵灰、搭橋為主要目標。根據(jù)帶塵煙氣的級別與煙塵特性，適用的爐型有：立式布置的強制循環(huán)水管鍋爐；臥式布置的強制循環(huán)水管鍋爐；雙鍋筒水管鍋爐。1.3粘結(jié)性煙氣煙氣的粘結(jié)性是指其在工作煙溫下，所挾帶的煙塵，集升華與氣化物質(zhì)等，在一定條件下粘附在鍋爐受熱面或其他部件上的特性。    A10VSO100: A10VSO100DFR/31L-PSC62K07,A10VSO100DFR1/31R-PUC12N00 A10VSO10: A10VSO10DFR1/52R-PKC64N00,A10VSO10DFR1/52R-PPA14N00,A10VSO10DR/52L-PKC64N00,A10VSO10DR/52R-PKC64N00,A10VSO10DR/52R-PPA14N00 A10VSO18: A10VSO18DFR/31R-PKC62N00,A10VSO18DFR/31R-PPA12K01,A10VSO18DFR/31R-PPA12N00,A10VSO18DFR1/31R-PPA12K01,A10VSO18DFR1/31R-PPA12N00 A10VSO18DFR1/31R-PUC62N00,A10VSO18DR/31L-PUC12N00,A10VSO18DR/31R-PPA12N00,A10VSO18DR/31R-PSC12N00,A10VSO18DRG/31R-PPA12N00 A10VSO28: A10VSO28DFLR/31L-PPA12N00,A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PPA12N00 A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PPA12N00,A10VSO28DFLR/31R-PSA12N00 A10VSO28DFR/31R-PPA12N00,A10VSO28DFR/31R-PPA12N00,A10VSO28DFR/31R-VPA12N00,A10VSO28DFR1/31R-PPA12L30,A10VSO28DFR1/31R-PPA12N00 A10VSO28DFR1/31R-PSC12N00,A10VSO28DFR1/31R-PSC62N00,A10VSO28DG/31R-PPA12N00,A10VSO28DR/31L-PPA12N00,A10VSO28DR/31R-PPA12N00 A10VSO28DRG/31R-PPA12K25,A10VSO28DRG/31R-PPA12N00,A10VSO28ED73/52L-VSC11N00P A10VSO45: A10VSO45DFLR/31R-PPA12K57,A10VSO45DFLR/31R-PPA12N00,A10VSO45DFLR/31R-PPA12N00,A10VSO45DFLR/31R-PPA12N00,A10VSO45DFLR/31R-PPA12N00 A10VSO45DFLR/31R-PPA12N00,A10VSO45DFLR/31R-PPA12N00,A10VSO45DFLR/31R-PPA12N00,A10VSO45DFR/31R-PPA12N00,A10VSO45DFR/31R-PPA12O30 A10VSO45DFR/31R-PSC62N00,A10VSO45DFR/52R-PSC12N00,A10VSO45DFR1/31R-PPA12G60,A10VSO45DFR1/31R-PPA12K54,A10VSO45DFR1/31R-PPA12K57 A10VSO45DFR1/31R-PPA12N00,A10VSO45DFR1/31R-PPA12N00,A10VSO45DFR1/31R-PPA12N00,A10VSO45DFR1/52L-PSC11N00,A10VSO45DFR1/52R-PUC11N00 A10VSO45DR/31R-PPA12K01,A10VSO45DR/31R-PPA12K25,A10VSO45DR/31R-PPA12K57,A10VSO45DR/31R-PPA12N00,A10VSO45DR/31R-PPA12O90 A10VSO45DRG/31R-PPA12N00,A10VSO45ED72/52R-VSC11N00T A10VSO60: A10VSO60DFR/52R-PCD11N00 A10VSO71: A10VSO71DFLR/31R-PPA12N00,A10VSO71DFLR/31R-PPA12N00,A10VSO71DFR/31L-PSC62N00,A10VSO71DFR1/31R-PSC12N00,A10VSO71DRG/31L-PSC12N00 AA10VSO100: AA10VSO100DFLR/31R-PPA12G30,AA10VSO100DFLR/31R-PPA12N00,AA10VSO100DFLR/31R-PPA12N00,AA10VSO100DFLR/31R-PPA12N00 AA10VSO100DFLR/31R-PPA12N00,AA10VSO100DFLR/31R-PPA12N00,AA10VSO100DFR/31R-PPA12K01,AA10VSO100DFR/31R-PPA12K25, AA10VSO100DFR/31R-PPA12N00,AA10VSO100DFR1/31R-PPA12K25,AA10VSO100DFR1/31R-PPA12N00,AA10VSO100DFR1/31R-PPA12N00,AA10VSO100DFR1/31R-PPA12N00, AA10VSO100DR/31R-PPA12N00,AA10VSO100DR/31R-PPA12N00,AA10VSO100DR/31R-VPA12N00,AA10VSO100DRG/31R-PPA12N00 AA10VSO140: AA10VSO140DFLR/31R-PPB12N00,AA10VSO140DFLR/31R-PPB12N00,AA10VSO140DFLR/31R-PPB12N00,AA10VSO140DFLR/31R-PPB12N00, AA10VSO140DFLR/31R-PPB12N00,AA10VSO140DFLR/31R-PSB12N00,AA10VSO140DFR/31R-PPB12N00,AA10VSO140DFR1/31R-PPB12N00,AA10VSO140DFR1/31R-PPB12N00,AA10VSO140DFR1/31R-VPB12N00,AA10VSO140DR/31L-PPB12N00,AA10VSO140DR/31R-PPB12K02,AA10VSO140DR/31R-PPB12N00,AA10VSO140DRG/31R-PPB12N00 AA10VSO71: AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFLR/31R-PPA12N00, AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFLR/31R-PPA12N00, AA10VSO71DFLR/31R-PPA12N00,AA10VSO71DFR/31R-PPA12K01,AA10VSO71DFR/31R-PPA12N00,AA10VSO71DFR1/31R-PPA12K01, AA10VSO71DFR1/31R-PPA12L30,AA10VSO71DFR1/31R-PPA12N00,AA10VSO71DFR1/31R-PPA12N00,AA10VSO71DFR1/31R-PPA12X31, AA10VSO71DR/31R-PPA12N00,AA10VSO71DRG/31R-PPA12K01,AA10VSO71DRG/31R-PPA12N00,AA10VSO71FHD/31R-PPA12K01 |
