Uketshezi olubuyayo
1. Ngohlelo lwesiqandisi usebenzisa i-valve yokwandisa, uketshezi olubuyayo luhlobene eduze nokukhethwa nokusetshenziswa okungafanele kwe-valve yokwandisa.Ukukhethwa okukhulu kwe-valve yokwandisa, ukusetha okuncane kakhulu kokushisa, indlela yokufaka engalungile yephakheji yokuzwa izinga lokushisa noma ukulimala kokupakisha kwe-adiabatic. , ukwehluleka kwe-valve yokwandisa kungase kuholele ekubuyeni koketshezi.
2. Ezinhlelweni ezincane zesiqandisi zisebenzisa ama-capillary, inani eleqile lokwengeza uketshezi lizobangela ukubuya koketshezi.Lapho isithwathwa esishunqamuzayo kabi noma isiphephetha-moya sihluleka, ukudluliswa kokushisa kuba kubi kakhulu. Ukushintshashintsha kwezinga lokushisa okuvamile nakho kungabangela ukwehluleka ukusabela kwe-valve yokwandisa futhi kubangele uketshezi. buyela.
Umshini uqala ngoketshezi
Isenzakalo sokubhamuza okukhulu kwamafutha okugcoba ku-compressor kubizwa ngokuthi ukuqala ngoketshezi.Isenzakalo sokubhuquza ngesikhathi kuqala uketshezi singabonakala ngokucacile kububanzi bawoyela.Isizathu esiyisisekelo ukuthi inani elikhulu lesiqandisi lincibilika phakathi amafutha okugcoba futhi acwiliswe emafutheni okugcoba.Lapho ukucindezela kwehla ngokuzumayo, kuvele kubile.
Uwoyela uyabuya
1. Uma indawo ye-compressor iphakeme kune-evaporator, ukugoba kokubuyisela uwoyela mpo kuyadingeka epayipini lokubuyisela kuyadingeka.Buyisa ukugoba kwamafutha kuqine ngangokunokwenzeka ukuze unciphise ukugcinwa kwamafutha.Ibanga phakathi kokugoba kokubuyisela uwoyela kufanele lifanele. , inani lokugoba kwamafutha likhulu, amanye amafutha okugcoba kufanele afakwe.
2. Ukuqala njalo kwe-compressor akuhambisani nokubuyiselwa kukawoyela.Ngenxa yokuthi i-compressor yayeka ukusebenza isikhathi esifushane kakhulu, sasingekho isikhathi sokwenza ukugeleza komoya okuzinzile kwesivinini esikhulu epayipini lokubuya, ngakho uwoyela wokugcoba wawungaba kuphela. ishiywe epayipini.I-compressor izophelelwa uwoyela uma uwoyela obuyayo ungaphansi kukawoyela asebenzayo.Uma isikhathi sokusebenza sisifishane, iba yinde ipayipi, yilapho uhlelo luyinkimbinkimbi kakhulu, kuba bucayi kakhulu inkinga yokubuya kukawoyela.
3. Ukuntuleka kwamafutha kuzodala ukushoda okukhulu kwe-lubrication.Isizathu esiyisisekelo sokuntuleka kwamafutha akulona inani nesivinini se-compressor, kodwa ukubuya kwamafutha omubi wesistimu.Ukufakwa kwesihlukanisi samafutha kungabuyisela ngokushesha amafutha, ukwandisa isikhathi sokusebenza kwe-compressor ngaphandle kokubuya kwamafutha.
Izinga lokushisa lokuhwamuka
Izinga lokushisa lokuhwamuka linomthelela omkhulu ekusebenzeni kahle kwesiqandisi.Ngaso sonke isikhathi lapho kuncipha ngedigri engu-1, inani elifanayo lokupholisa lidinga ukwandisa amandla ngo-4%.Ngakho-ke, kuyazuzisa ukukhulisa ukusebenza kahle kokupholisa kwesimo somoya ngokwandisa izinga lokushisa lokuhwamuka ngokufanelekile ngaphansi kwesimo sokuvumela.
Ukwehlisa ngobumpumputhe izinga lokushisa lokuhwamuka kungapholisa umehluko wokushisa, kodwa inani lokupholisa i-compressor liyancishiswa, ngakho-ke isivinini sesiqandisi asisheshi ngempela. uma isikhathi sokusebenza sikhula, ukusetshenziswa kukagesi kuya phezulu.
Izinga lokushisa elikhipha umoya ngokweqile
Izizathu zokushisa okuphezulu kokukhishwa yilezi ezilandelayo: izinga lokushisa eliphezulu lokubuyisela, ukushisa okuphezulu okwengezwe yi-motor, isilinganiso esiphezulu sokucindezela, ukucindezela okukhulu kokucindezela, ukushisa kwe-adiabatic index of refrigerant, ukukhetha okungalungile kwesiqandisi.
Umthelela woketshezi
1. Ukuze kuqinisekiswe ukusebenza okuphephile kwe-compressor futhi kuvimbele ukuvela kwe-liquid percussion, izinga lokushisa lokudonsa liyadingeka ukuba libe phezulu kancane kunokushisa kokuhwamuka, okungukuthi, izinga elithile lokushisa okukhulu liyadingeka.
2. Izinga lokushisa lokuphefumula kufanele libe phezulu kakhulu noma libe phansi kakhulu.Izinga lokushisa eliphakeme kakhulu lokudonsa, okungukuthi, ukushisa ngokweqile, kuzoholela ekushiseni okuphezulu kwe-compressor.Uma izinga lokushisa lokuphefumula liphansi kakhulu, libonisa ukuthi isiqandisi asishunqisi ngokuphelele. ku-evaporator, enganciphisi nje kuphela ukusebenza kahle kokushintshaniswa kokushisa kwe-evaporator, kodwa futhi yakha ukushaqeka okuwuketshezi kwe-compressor.Izinga lokushisa lokudonsa ngaphansi kwezimo ezivamile kufanele libe ngu-5 ~ 10 ℃ ngaphezu kwezinga lokushisa lokuhwamuka.
I-Fluorine
Uma kune-fluoride encane noma umfutho wayo olawulayo uphansi (noma uvaleke kancane), isembozo sevalvu yevalvu yokunweba (izimbongolo) noma ngisho nendawo yokungena yevalvu izoba yiqhwa.Lapho inani lefluorine lilincane kakhulu noma alinayo i-fluorine. , ukubukeka kwe-valve yokwandisa akuphenduli, kuzwakala kuphela ukugeleza komoya okuncane.
Bona ukuthi yikuphi ukuphela kweqhwa eliqala ukusuka, kusukela ku-nozzle noma kusukela ku-compressor emuva ku-trachea, uma kusuka ku-nozzle kuntuleka kwe-fluorine, kusukela ku-compressor kune-fluorine eningi.
Izinga lokushisa eliphansi lokumunca
1. Inani lokugcwalisa isiqandisi likhulu kakhulu, lithatha ingxenye yevolumu ye-condenser futhi likhulisa ukucindezela kokunciphisa, futhi uketshezi olungena ku-evaporator luzokhula ngokufanele.Uketshezi oluku-evaporator alukwazi ukuhwamuka ngokuphelele, ukuze i-compressor imunce igesi. ngeconsi eliwuketshezi.Ngakho, izinga lokushisa lepayipi legesi elibuyayo liyehla, kodwa izinga lokushisa lokuhwamuka lihlala lingashintshile ngenxa yokuthi ukucindezela akunciphi, futhi ukushisa okukhulu kuyehla.Ngisho nokuvala i-valve encane yokwandisa akuzange kube ngcono kakhulu.
2. I-valve yokunweba ivulwe inkulu kakhulu.Ngenxa yokubopha okuxekethile kwezinto ezizwa izinga lokushisa, indawo encane yokuxhumana nepayipi lomoya elibuyayo, noma indawo yokupakisha engafanele yezinto ezizwa izinga lokushisa ngaphandle kwezinto ze-adiabatic, izinga lokushisa elilinganiswa ngezici zokuzwa izinga lokushisa alinembile. futhi eduze nezinga lokushisa le-ambient, okwandisa izinga lokuvula lokunyakaza kwe-valve yokwandisa futhi kuholele ekunikezeni uketshezi okweqile.
Izinga lokushisa eliphezulu lokumunca
1. Kuhlelo, inani lokugcwalisa isiqandisi alanele, noma i-valve yokwandisa ivulwa encane kakhulu, okuholela ekutheni inani elinganele lokujikeleza kwesiqandisi sesistimu, futhi umthamo wefriji we-evaporator uphansi futhi ukushisa okuphezulu kuphezulu, ngakho izinga lokushisa lokumunca liphezulu.
2. Isikrini sokuhlunga embobeni ye-valve yokunweba sivinjiwe, inani loketshezi olunikezwa ku-evaporator alanele, inani loketshezi oluyisiqandisi liyancishiswa, futhi ingxenye ye-evaporator ihlalwa isitimu esishisa kakhulu, ngakho-ke izinga lokushisa lokudonsa liyakhuphuka. .
3. Ngenxa yezinye izizathu, izinga lokushisa lokuhogela liphezulu kakhulu, njengokufakwa kokushisa okubi kwepayipi lomoya elibuyayo noma ipayipi elide kakhulu, okungabangela izinga lokushisa lokuhogela libe phezulu kakhulu.Ngaphansi kwezimo ezijwayelekile, isembozo se-compressor cylinder kufanele sibe uhhafu. kupholile, kushisa kancane.
Izinga lokushisa eliphansi le-Exhaust
Ingcindezi yokukhipha umoya iphansi kakhulu, nakuba isimo sayo sibonakala ekugcineni komfutho ophakeme, kodwa isizathu ngokuvamile sisekugcineni kwengcindezi ephansi.Izizathu yilezi:
1. I-ice block noma ibhulokhi engcolile yevalvu yokunweba, ibhulokhi yesihlungi, njll., nakanjani izonciphisa ukumunca kanye nengcindezi yokukhipha umoya; Imali enganele yesiqandisi;
2. Imbobo ye-valve yokwandisa ivinjiwe, futhi ukunikezwa koketshezi kuyancishiswa noma kumiswe.Ngalesi sikhathi, ingcindezi yokudonsa kanye ne-exhaust iyancishiswa.
I-HERO-TECH I-Industrial water chiller
Ama-compressor omkhiqizo adumile emhlabeni wonke kanye ne-condenser ephezulu ne-evaporator, iqinisekisa ukusebenza kahle kokupholisa okuphezulu, ukusetshenziswa kwamandla okuphansi, umsindo ophansi nempilo ende yesevisi.
I-evaporator ne-condenser enosayizi ongaphezu kosayizi iqinisekisa iyunithi ye-chiller egijima ngaphansi kwezinga lokushisa le-ambient elingu-45ºC eliphezulu.
Isistimu yokulawula yamakhompiyutha amancane enikeza ukuzinza okunembile kwezinga lokushisa phakathi kuka-±1ºC.
I-evaporator-in-tank configuration iqinisekisa izinga lokushisa lamanzi elizinzile elinikezwayo, njengoba i-evaporator iphinda ipholise ithangi ngokwalo, inciphise ukushisa okuzungezile futhi, futhi ikhuphule ukusebenza kahle.
