Okokuqala, ukuhlaziywa kokwehluleka kanye nokwelashwa kwamazinga okushisa okugcina amakhaza awehli
Ukushisa kwesiqandisi kuphakeme kakhulu. Ngemuva kokuhlolwa, izinga lokushisa lezindawo zokugcina izimpahla ezindlini zokugcina ezimbili lalingu-4 ° C kuya ku-0 ° C, kanye nama-valesve we-solenoid we-solenoid wezindawo zokugcina izimpahla ezimbili zasheshe zavulwa. I-compressor yaqala kaningi, kepha lesi simo asithuthukanga lapho sishintshela komunye umcindezeli, kepha kwakukhona isithwathwa esikhulu epayipi lomoya. Ngemuva kokufaka lezi zindlu zokugcina izimpahla ezindlini, kwatholakala ukuthi isithwathwa esikhulu sakhiwe emakholini okuhwamuka, futhi isimo sathuthuka ngemuva kokuqamba. Ngalesi sikhathi, isikhathi sokuqalisa nokushisa kwesitoreji se-compressor sincishisiwe, kodwa hhayi okuhle. Bese uhlola imikhawulo ephezulu nangaphansi yesenzo somlawuli wengcindezelo ephansi, bese uthola ukuthi ukungalungiswa kwamaphutha ngu-0.11-0.15npa, okungukuthi, yeka i-compressor lapho ingcindezi lapho ingcindezi lapho ingcindezi ingu-0,15pa. Ibanga lokushisa elihambisanayo lokuhwamuka licishe licishe libe -20 ° C kuya ku-18 ° C. Ngokusobala, lokhu kulungiselelwa kuphakeme kakhulu futhi umehluko we-amplitude mncane kakhulu. Ngakho-ke, lungisa imikhawulo ephezulu nangaphansi yomlawuli wengcindezi ephansi. Inani elilungisiwe lingu-0.05-0.12mpa, kanye nebanga lokushisa elihambisanayo lokuhwamuka licishe libe-° C-18 ° C. Ngemuva kwalokho, qalisa kabusha uhlelo bese uqala ukusebenza okujwayelekile.
2. Izizathu eziningana zokuqalisa njalo kwe-compressional compressors
Ama-compressors agijimayo aqalwa futhi amise ngokudluliselwa kwamandla aphezulu aphansi futhi aphansi, kepha ngemuva kokudlulisela okuphezulu kakhulu kwamandla kagesi, ukusetha kabusha kwencwadi kufanele kwenziwe ukuqala kabusha i-compressor. Ngakho-ke, ukuqala okujwayelekile nokuma kwe-compressor ngokuvamile akubangelwa ukudluliselwa kwamandla aphezulu, kepha ikakhulukazi ngokudluliswa kwamandla aphansi aphansi:
1. Umehluko wokushisa phakathi kokudluliselwa kokudluliselwe futhi okudluliselwe kwevolumu ephansi kuncane kakhulu, noma umehluko wokushisa phakathi kokudluliselwa kokudlulisa kanye nokudluliswa kwamandla aphansi kuncane kakhulu;
2 Ngemuva kokuqala, ingcindezi yohlelo lwe-voltage ephansi yehla ngokushesha, i-low-voltage edlulayo iyasebenza, futhi i-compressor iyama;
I-3. I-automatic kawoyela i-valve yokuthambisa okuthayipha kwamafutha;
4. Ukunwetshwa i-valve ice plug.
3. I-compressor isebenza isikhathi eside kakhulu
Imbangela yesikhathi eside sokugijima kwe-compressor kungukunganele okupholile kwamandla okupholisa noma umthwalo omkhulu wokushisa wesitoreji esibandayo, ikakhulukazi kufaka phakathi:
1. I-evaporator ineqhwa eliningi kakhulu noma isitoreji samafutha amaningi;
2. Ukujikeleza okuqandisayo kusistimu akwanele, noma ipayipi eliyisiqandisi eliwuketshezi alibushelelezi ngokwanele;
3
4
5 Kepha i-comprescer ayikwazi ukuma ngesikhathi.
I-4. Ngemuva kokuthi i-compressor iyama, izingcindezi eziphakeme neziphansi zilingana ngokushesha
Lokhu kungenxa yokuvuza okungathi sína noma ukuqhekeka kwamapuleti we-valve kanye ne-gasket phakathi kwengcindezi ephezulu nengcindezi ephansi ye-cylinder, kanye nokungena okuphezulu kwegesi ephakeme ku-suction Chamber ngemuva kokuvalwa.
I-5. I-compressor ayikwazi ukulayishwa noma ilayishwe ngokujwayelekile
Okozinhlelo zomthethonqubo wamandla alawulwa yingcindezi kawoyela, isizathu esiyinhloko yile: Ukugcotshwa kwamafutha okugcoba kuphansi kakhulu. (Ngokuvamile okubangelwa ukukhishwa okweqile nokuvunyelwa kwepompo), kungaxazululwa ngokuqinisa ukucindezela kukawoyela okulawula i-valve; Isilinda sokulayisha isilinda sivuza uwoyela ngokungathí sina, bese umjikelezo kawoyela uvinjiwe; Isilinda kawoyela sinamathela esitokisini noma kwezinye izindlela; I-Solenoid valve ayisebenzi ngokujwayelekile, noma i-Iron Core inezinsalela ezisele.
I-6 ukwehluleka kwesistimu yokuqaphaka
1 Uma iqhwa likhulu kakhulu, ukumelana okushisayo kuzokhuphuka, okuholela ekulweni kokushisa okushisa okushisayo kokushisa phakathi komhwamuki kanye nesitoreji esibandayo. Isiqandisi asikwazi ukudonsa ukushisa okwanele ukuhwamuka ku-evaporator. Inani elikhulu lefriji lidonsa ukushisa epayipi lokubuya futhi lihwamuka, okukhulisa i-frosting yepayipi lokubuya; Ngaphezu kwalokho, i-superheat ezwakala yi-valve yokwanda incane kakhulu noma i-zero, ibangele ukuvala noma ukuvala, futhi i-compressor izoma ngengcindezi ephansi kungekudala. Kodwa-ke, i-solenoid valve ayivaliwe, futhi kusekhona umthwalo othile wokushisa esitoreni esibandayo. Ngemuva kwengcindezi ye-Evaporator kukhuphuke, i-compressor iqala futhi, ibangele ukuqala. Omkhulu uqhwa e-evaporator, okuzoba kubi kakhulu lesi simo. In fact, the frost on the evaporator coils of the two low-temperature cold storages in this system is too thick, reaching 1-2cm, which seriously affects the heat transfer and cannot reduce the storage temperature. Ngemuva kokuqamba, sebenzisa uhlelo futhi, futhi izinga lokushisa lezindawo zokugcina izindawo zokushisa eziphansi eziphansi lingangena ku-6-5 ° C.
2. Inani lokusetha lomlawuli ophakeme futhi ophansi akulungile: Isiqandisi esisetshenziswe emishini eqandisi ngu-R22, kanye nengcindezi ephezulu yokusika kagesi (umkhawulo ophezulu) ukhethwe kakhulu njengengcindezi yegeji ka-1.7-1.9MPA. Ingcindezi (umkhawulo ophansi) we-Low-Voltage Relall ingaba yingcindezi yokuqalwa kwe-Subrindid Ukwahluka kokulungiswa koshintsho lwe-low-voltage switch ngokuvamile 0.1-0.2MPA. Kwesinye isikhathi isilinganiso senani lokusetha okulawulwa kwengcindezi alilungile, futhi inani lesenzo sangempela lingaphansi kwenani elinganisiwe ngesikhathi sokulungisa iphutha. Lapho uvivinya isilawuli sengcindezelo ephansi, uvale kancane kancane i-valve evaliwe ye-compressor, bese unaka inani lenkomba ye-suction Pressure Gauge. Izinkomba zokubonisa lapho i-compressor imiswe futhi iqale kabusha yimikhawulo ephezulu nangaphansi yomlawuli wengcindezi ephansi. Ukuhlola isilawuli esiphakeme kakhulu sengcindezelo, ukuvala kancane ukukhishwa kokukhipha i-valve ye-compressor, futhi kufundwe ukufundwa kwe-compress tress gauge lapho i-compressor iyeka, okungukuthi, ingcindezi yokusika okuphezulu. Qinisekisa ukwethenjwa kwegeji yokucindezela ngaphambi kokuhlolwa; Ukuqinisekisa ukuphepha, i-valve yokukhipha akufanele ivalwe ngokuphelele.
I-3. Isiqandisi esinganele ohlelweni: Kudivayisi enethangi lokugcina uketshezi, ngenxa yokulungiswa kwethangi lokugcina uketshezi, ngaphandle kokuthi ngenxa yokushoda okukhulu kwethangi lokuqapha, ngaphandle ngenxa yokuqhubeka kwethangi lokugcina, okuzothinta ukusebenza okujwayelekile kwensiza. "Isiqandisi esiphansi", okungukuthi izinga lamanzi aphansi, ngeke abe nomthelela omkhulu ekusebenzeni kohlelo. Kodwa-ke, kudivayisi ngaphandle kwethangi lokugcina eliwuketshezi, ngoba inani lesiqandisi elisesigabeni linquma ngqo i-aclenser yesiqandisi esiqandayo, lapho kutholakala khona okuqandayo, kuzoholela ezinguquko ezilandelayo ezimweni zokusebenza zemishini:
(1) I-compressor ilokhu isebenza, kepha izinga lokushisa lesitoreji alikwazi ukwehliswa;
(2) ingcindezi yokuqeda amandla ka-compressor iyancishiswa;
.
(4) Inani elikhulu lama-bubble lingabonakala esikhungweni sokugeleza esilinganayo sesinkomba yokuhlinzekwa koketshezi;
(5) Izinga loketshezi lomquba ngokusobala liphansi.
Lapho ukuvulwa kwe-Thermal Expension Valve kulungiswe incane kakhulu, ingcindezi yokumunca izokwehla, umqulu uzokwehliswa futhi ancibilike, futhi ipayipi lokumunca lizoncibilika futhi lincibilike. Ngakho-ke, lapho izinga lesiqandisi lingabonakali kahle. Ukuze ahlulele ukuthi inani lesiqandisi esiqandisiwe ohlelweni alwanele, izindlela ezilandelayo zingasetshenziswa:
Misa ukusebenzisa i-Thermal Expension Valve, vula futhi ulungise i-valve ye-Manual Expention ngokufanele, bese ubheka ukusebenza kohlelo ukubona ukuthi ingabuyela kokujwayelekile. Uma ingabuyela kokujwayelekile, kusho ukuthi i-valve yokunwebeka eshisayo ayilungiswa kahle, uma kungenjalo kunokuntuleka kwesiqandisi. Isiqandisi esinganele ohlelweni (uma kungenjalo inkokhelo enganele) yimbangela yokuvuza. Ngakho-ke, ngemuva kokuthi inqobo isinqumo sokuthi isiqandisi se-STEMSTION angenele, ukuvuza kufanele kutholakale kuqala, futhi esiqandisi kufanele sengezwe ngemuva kokususwa okuvuzayo.
