Njengengxenye eyinhloko yomshini wokomisa oqandisayo, iphampu ye-vacuum idlala indima ebalulekile enkambisweni yokomisa oqandisayo. Umshini wokomisa oqandisayo (i-lyophilizer) uyingxenye yemishini esetshenziswa kabanzi embonini yokudla, yezemithi, kanye neyamakhemikhali. Ngokuqandisa nokufaka izinto ngaphansi kwezimo zokushisa eziphansi kanye nokucindezela okuphansi, kufinyelela isimo somswakama ongenamanzi noma ophansi, ngaleyo ndlela kwandise impilo yeshelufu yezinto futhi kuthuthukiswe ukuzinza kwazo.
Umsebenzi Oyisisekelo Wephampu Yokushaja I-Vacuum
Umsebenzi oyinhloko wepompo ye-vacuum kumshini wokomisa oqandisayo ukusungula nokugcina indawo ye-vacuum, ebalulekile enqubweni yokomisa oqandisayo. Ipompo ye-vacuum isusa igesi njalo ohlelweni, inciphisa kancane kancane ingcindezi yangaphakathi. Lapho ingcindezi yehla iye ezingeni elithile, umswakama ezintweni uqala ukushintsha ngqo kusuka kokuqinile kuya kugesi - inqubo ebizwa ngokuthi i-sublimation - ngaleyo ndlela kufezwe ukomisa okuqandisayo kwezinto.
Ngokukhethekile, ukusetshenziswa kanye nendima yephampu ye-vacuum kumshini wokomisa oqandisayo kubonakala kulezi zici ezilandelayo:
Ukudala indawo yokuhlanza umoya:Iphampu yokufutha isusa umoya ekamelweni lokomisa, yehlise ingcindezi ngaphakathi futhi idale indawo yokufutha i-vacuum. Le ndawo ivumela iqhwa elikumkhiqizo ukuthi lingene ngqo emfuleni wamanzi ngaphansi kwengcindezi ephansi, igweme inqubo yokuncibilika kweqhwa libe uketshezi bese lihwamuka, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokomisa.
Ukulawula ingcindezi:Ngesikhathi sokomisa ngeqhwa, iphampu ye-vacuum ingalungisa futhi igcine ingcindezi ngaphakathi kwegumbi lokomisa ngaphakathi kobubanzi obufanele. Lokhu kubalulekile ukuze kwenziwe i-sublimation ephumelelayo, ngoba izinto zokwakha nemikhiqizo ehlukene inezinga elihlukile le-sublimation ngaphansi kwengcindezi ehlukene.
Ukuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo:Imishini yokupompa i-vacuum esebenza kahle kakhulu ingafinyelela ngokushesha ezingeni le-vacuum elidingekayo, ifinyeze isikhathi sokomisa i-freeze, futhi yandise ukusebenza kahle kokukhiqiza. Ngesikhathi esifanayo, ivikela ikhwalithi yomkhiqizo ngokunciphisa izinsalela ezingcolile. Lokhu kubaluleke kakhulu ezinkampanini ezikhiqiza izinto ezomisiwe ezifriziwe, njengoba kuthinta ngqo ukuncintisana komkhiqizo emakethe.
Ukonga izindleko zamandla:Iphampu ye-vacuum enhle ingafinyelela izinga le-vacuum elidingekayo ngesikhathi esifushane, ngaleyo ndlela inciphise ukusetshenziswa kwamandla. Kuma-dryer dryers asebenza njalo, lokhu kuholela ekongeni amandla okukhulu.
Izinhlobo Nokukhethwa Kwamaphampu Okuhlanza I-Vacuum
Izinhlobo ezivamile zamaphampu e-vacuum asetshenziswa kuma-dryer dryers zifaka phakathi amaphampu e-vacuum e-rotary vane, amaphampu e-vacuum e-centrifugal, kanye namaphampu e-turbomolecular. Uhlobo ngalunye lunezinzuzo zalo kanye nezimo ezifanele:
Iphampu yokuvaleka ye-vacuum ye-Rotary vane:Yaziwa ngobukhulu bayo obuncane, isisindo esilula, isakhiwo esilula, kanye nokugcinwa okulula, le phampu isetshenziswa kabanzi ezinhlelweni ezidinga i-vacuum ephezulu noma isivinini esikhulu sokupompa. Ikhipha igesi ngendlela ye-vacuum ejikelezayo futhi ingafinyelela i-vacuum ephezulu ngesikhathi esifushane, isheshise ukufakwa komswakama.
Iphampu ye-vacuum ye-Centrifugal:Njengoba inesivinini esikhulu sokupompa, i-vacuum ephezulu, kanye ne-gas flow enkulu, lolu hlobo lufanelekela izinhlelo ze-vacuum ezinkulu. Lusebenzisa amandla e-centrifugal akhiqizwa ukujikeleza kwesivinini esikhulu ukukhipha igesi, okuhlangabezana nezidingo zokukhiqizwa ngobuningi.
Iphampu ye-Turbomolecular:Inikeza isivinini esikhulu, i-vacuum ephezulu kakhulu, usayizi omncane, kanye nokusetshenziswa kwamandla okuphansi, iphampu ye-turbomolecular ilungele izinhlelo zephampu ye-vacuum enembile. Ikhipha igesi nge-turbine ejikelezayo ngesivinini esikhulu futhi inganikeza umfutho wesistimu ophansi kakhulu, ihlangabezane nezidingo zokulungiselela izinto ezihlanzekile kakhulu.
Uma ukhetha iphampu ye-vacuum, izici ezifana nesivinini sokupompa, ububanzi bokucindezela kokusebenza, ukuhlanzeka kwendawo yokusebenza, kanye nezindleko zokulungisa kufanele kucatshangelwe. Ngesikhathi esifanayo, ukuqinisekisa ukusebenza okuvamile kwe-freezer dryer nokwandisa impilo yayo yesevisi, kudingeka ukulungiswa njalo kwephampu ye-vacuum - okuhlanganisa ukuhlola izivalo, umthamo wokumunca, kanye nokufaka uwoyela wephampu ye-vacuum esikhundleni.
Isiphetho
Njengengxenye eyinhloko yomshini wokomisa oqandisayo, ukusebenza kwepompo yokuhlanza kuthinta ngqo ukusebenza kahle kanye nokuphepha kwemishini. Ngokudala nokugcina indawo yokuhlanzayo, ipompo yokuhlanzayo ayigcini nje ngokuthuthukisa ukusebenza kahle kwenqubo yokomisa oqandisayo kanye nekhwalithi yomkhiqizo, kodwa futhi isiza amabhizinisi ukuthi onge izindleko zamandla. Ngakho-ke, lapho ukhetha ipompo yokuhlanzayo, kubalulekile ukucabangela ngokuphelele izici ezahlukahlukene ngokusekelwe ezidingweni zangempela, ukuqinisekisa ukukhethwa kwemishini yokuhlanzayo esezingeni eliphezulu, nokwenza ukulungiswa njalo ukuqinisekisa ukusebenza okuvamile komshini wokuhlanzayo oqandisayo nokwandisa impilo yawo yesevisi.
