Ithini Incazelo Eyinhloko Ye-Detachable Plate Heat Exchanger? Yiziphi Izingxenye Zawo Eziyinhloko?

Incazelo Yomkhiqizo

I-detachable plate heat exchanger (GPHE) iyithuluzi eliphezulu-lokushintsha ukushisa eliklanywe ngokusekelwe kumgomo wokudlulisa ukushisa okungaqondile. Umnyombo wayo uqukethe uchungechunge lwamapuleti kathayela anezitembu, ama-gaskets, amafreyimu asekelayo, nama-clamping bolt.Amapuleti ahlukaniswa futhi apakishwe ngama-gaskets avalayo ukuze akhe amashaneli okugeleza anezikhala ezizimele. Uketshezi olubandayo nolushisayo lugeleza ngokushintshana eziteshini eziseduze, futhi ukudluliswa kokushisa kuqedwa ukuqhutshwa kokushisa okuphezulu kwamapuleti ensimbi. Ngesikhathi esifanayo, izingxenye zingahlakazwa ukuze kuzuzwe ukuhlanza, ukugcinwa nokulungiswa kwesakhiwo. Ingenye yezinsiza ezibalulekile zokulawula amandla ashisayo emikhakheni yezimboni neyomphakathi.

A: Izishintshi zokushisa zepuleti ezidonsekayo zingamadivayisi okushintsha ukushisa-okuphezulu aklanywe ngokusekelwe kumgomo wokudlulisa ukushisa okungaqondile. Zihlukaniswa zibe iziteshi zokugeleza ezizimele ngamapuleti ensimbi enziwe uthayela, okuvumela uketshezi olubandayo nolushisayo ukuthi lugeleze eziteshini eziseduze kanye nokudlulisa ukushisa okuphelele. Ngaphezu kwalokho, ukugcinwa nokulungiswa kungafinyelelwa ngokuqaqa izingxenye.Izingxenye eziwumgogodla zihlanganisa amashidi kathayela anezitembu, ama-gaskets avalayo, ama-clamping plate angaguquki, ama-clamping plate anyakazayo, ama-guide rods, ama-clamping bolt, namafreyimu asekelayo.

A: Umgomo wokusebenza umi kanje: amapuleti ayavalwa futhi apakishwe ngama-gaskets ukuze akhe amasethi amabili eziteshi zokugeleza ezishintshanayo nezingawodwa. Uketshezi olubandayo nolushisayo lungena kumashaneli okugeleza ahambisanayo futhi ageleze ngendlela yokubala-yamanje noma{2}indlela yamanje. Ukushisa kudluliselwa ngokuphumelelayo ngosizo lwamapuleti ensimbi ane-conductivity ephezulu ye-thermal.Umehluko oyinhloko usendleleni yokuvala futhi kulula ukugcinwa{5}}izinhlobo ezikhishwayo zisebenzisa ama-gasket seal, angahlakazwa kalula ukuze kuhlanzwe kanye nokwengezwa noma ukususwa kwamapuleti;-izinhlobo ezingakhipheki ngokuvamile ezisebenzisa izinti ezishiselwe, okuthi, nakuba zimelana nezinga lokushisa eliphezulu nokucindezela, ezingakwazi ukuhlakazwa ukuze zilungiswe.

1. Umbuzo: Uma kuqhathaniswa negobolondo lendabuko kanye nezishintshisi zokushisa zamashubhu, yiziphi izinzuzo zokushintshisana kokushisa kwepuleti elikhiphekayo ngokusebenza kahle kokudlulisa ukushisa kanye nomsebenzi wesikhala?

I: Mayelana nokusebenza kahle kokudlulisa ukushisa, isakhiwo sepuleti likathayela sesishintshi sokushisa sepuleti elilahlekayo singadala isiphithiphithi esinamandla oketshezini ezinombolweni eziphansi ze-Reynolds, nge-coefficient yokudlulisa ukushisa izikhathi ezi-3-5 izikhathi ezingu-5 kunesheli-kanye{4}}nohlobo lweshubhu, futhi umehluko wetheminali wetheminali ungaba ngaphansi kuka-1℃(igobolondo le-tube degree{9}}futhi i-tube type 5 degrees{9}}igama elithi tu{9} livamise ukuba yidigri engu-5). ukuhlala kwesikhala, indawo yayo yokushintsha ukushisa ngeyunithi ngayinye iphindwe izikhathi ezingu-2-5 kuneyegobolondo-kanye{15}}nohlobo lweshubhu, futhi isikhala sayo singu-1/5-1/8 kuphela sohlobo lwegobolondo neshubhu. Asikho isidingo sokugcina isikhala sokukhishwa kwenqwaba ye-tube, futhi isakhiwo sihlangene kakhulu.

2.Q: Yiziphi izindlela eziqondile lapho "ukususwa" kwesishintshi sokushisa kwepuleti elikhiphekayo kubonakaliswa ngaziphi izindlela? Iliphi inani lohlelo lokusebenza olulethwa yilesi sici?

A: "Okususwayo" kusho ukuthi ungakwazi ukuhambisa i-clamping plate ngokukhulula ama-clamping bolt, futhi ukhiphe ipuleti ukuze lihlanzwe, lihlolwe noma lishintshwe. I-gasket yokuvala ingaphinda ikhishwe futhi ifakwe ngokuhlukana (i-snap-ku-gasket ilungele ukushintshwa). Izinhlelo zokusebenza ezisebenzayo zihlanganisa: ukuhlanza okuvamile kwesikali ukuze kugcinwe ukusebenza kahle kokushintshanisa ukushisa; ukulungiswa okuguquguqukayo kwendawo yokushintshanisa ukushisa ngokukhula noma ukunciphisa amapuleti ukuze kufakwe izinguquko ezimweni zokusebenza; kanye nokushintshwa komuntu ngamunye kwezingxenye ezilimele ukuze kuncishiswe izindleko zokulungisa kanye nesikhathi sokuphumula.

3.Umbuzo: Iyini imikhawulo yezishintshi zokushisa zamapuleti akhiphekayo ngesikhathi sokusebenza? Yiziphi izimo okufanele zigwenywe lapho uzisebenzisa?

A: Imikhawulo iphindwe kathathu: Okokuqala, ngenxa yemikhawulo yezinto ze-gasket, ingcindezi yokusebenza ngokuvamile ayidluli u-2.5MPa, futhi izinga lokushisa eliphakathi akufanele lidlule i-250℃;Okwesibili, iziteshi zokugeleza phakathi kwamapuleti amancane (kuphela 2-}5mm), okwenza ukuthi avinjwe kalula yimidiya equkethe izinhlayiya ezinkulu, i-seal imitha ye-fiber ende; ukuvuza. Izimo okufanele zigwenywe zifaka: -izinga lokushisa eliphezulu kakhulu-nezimo zengcindezi ephezulu kakhulu, izimo lapho okuphakathi kuqukethe inani elikhulu lokungcola noma amafayibha, kanye nezimo ezinobungozi obuphezulu bokushintshana kokushisa okungenakubekezelela ukuvuza.

Umbuzo: Yimiphi imisebenzi yokushintshisana yokushisa eyinhloko yesishintshi sokushisa sepuleti elikhiphekayo? Yiziphi izimo zokudlulisa ukushisa okufanele?

IMP: Imisebenzi yokushintshisana yokushisa ewumongo ihlanganisa ukushisisa, ukupholisa, ukufingqa, ukuhwamuka, nokubuyiswa kokushisa kwemfucuza. Ifanele izimo ezihlukene zokudlulisa ukushisa.Isibonelo: ukushintshana kokushisa kwamanzi ashisayo nabandayo kumasistimu amaphakathi omoya, ukulawulwa kwezinga lokushisa kwenqubo yemidiya ekukhiqizeni izimboni, ukuvala inzalo nokupholisa ekucutshungulweni kokudla, ukupholisa kwamanzi azungezayo ezikhungweni zikagesi, nokutholwa nokusetshenziswa kabusha{2}}kwezinga eliphansi lokushisa kwemfucuza.
