1.Qala bese umisa kuqala
Ngaphambi kokuqala, ukuxhumanisa kumele kuhlelwe kabusha. Uma uqala okokuqala, kufanele uqale uhlole izimo zokusebenza zazo zonke izingxenye ze-compressor kanye nezingxenye zikagesi.
Izinto zokuhlola zimi kanje:
a. Vala inkinobho yamandla bese ukhetha indawo yesandla yenkinobho yokukhetha;
b. Cindezela inkinobho ye-alamu, kuzokhala insimbi ye-alamu; cindezela inkinobho yokuthula, i-alamu izosuswa;
c, Cindezela inkinobho yokushisa kagesi bese isibani senkomba sivuliwe. Ngemva kokuqinisekisa ukuthi isifudumezi sikagesi siyasebenza, cindezela inkinobho yokumisa ukushisa bese isibani senkomba yokushisa sivaliwe;
d. Cindezela inkinobho yokuqalisa iphampu yamanzi, iphampu yamanzi iyaqala, isibani senkomba sivuliwe, cindezela inkinobho yokumisa iphampu yamanzi, iphampu yamanzi iyama, bese isibani senkomba sivaliwe;
e. Cindezela inkinobho yokuqala yepompo yamafutha, isibani sesikhombisi sepompo yamafutha sivuliwe, ipompo yamafutha isebenza futhi ijikeleza ngendlela efanele, futhi umehluko wokucindezela kwamafutha ulungiswa ube ngu-0.4 ~ 0.6MPa. Phendula ivalvu enezindlela ezine noma ucindezele inkinobho yokwenyusa/ukwehlisa umthwalo ukuze uhlole ukuthi ivalvu yesilayidi kanye nedivayisi ekhombisa amandla kusebenza kahle yini, futhi isibonakaliso sokugcina sezinga lamandla sisendaweni ethi “0”.
Hlola inani elibekiwe le-relay noma uhlelo ngalunye lokuvikela ukuphepha oluzenzakalelayo/izinga lokushisa le-compressor kanye nenani lereferensi lokuvikelwa kwengcindezi:
a. Ukuvikelwa komfutho ophezulu wokukhipha ugesi: umfutho wokukhipha ugesi≦1.57MPa
b. Ukuvikelwa kokushisa okuphezulu komjovo kaphethiloli: izinga lokushisa lomjovo kaphethiloli ≦65℃
c. Ukuvikelwa komehluko wokucindezela uwoyela okuphansi: umehluko wokucindezela uwoyela ≧0.1MPa
d. Ukuvikelwa komehluko wokucindezela okuphezulu ngaphambi nangemva kwesihlungi esincane: umehluko wokucindezela ≦0.1MPa
e. Ukuvikelwa kwengcindezi yokumunca okuphansi: kusethwe ngokwezimo zokusebenza zangempela
Ngemva kokuhlola izinto ezingenhla, ingavulwa
Izinyathelo zokuvula yilezi ezilandelayo:
a. Iswishi yokukhetha ivulwa ngesandla;
b. Vula ivalvu yokuvala yokukhipha i-compressor;
c. Layisha i-compressor uye endaweni ethi “0″, okuyisikhundla somthwalo esingu-10%;
d. Qala iphampu yamanzi okupholisa kanye nephampu yamanzi esiqandisini ukuze unikeze amanzi ku-condenser, ku-oyela cooler kanye naku-evaporator;
e. Qala ipompo kawoyela;
f. Imizuzwana engama-30 ngemva kokuba ipompo kawoyela iqalisiwe, umehluko phakathi kwengcindezi kawoyela kanye nengcindezi yokukhipha ugesi ufinyelela ku-0.4 ~ 0.6MPa, cindezela inkinobho yokuqala i-compressor, i-compressor iyaqala, kanye ne-bypass solenoid valve A nayo ivuleka ngokuzenzakalelayo. Ngemva kokuba imoto isebenza ngokujwayelekile, i-valve A ivalwa ngokuzenzakalelayo;
g. Qaphela igeyiji yokucindezela kokumunca, vula kancane kancane ivalvu yokumisa ukumunca bese ukhuphula umthwalo ngesandla, futhi unake ukuthi ingcindezi yokumunca ingabi phansi kakhulu. Ngemva kokuba i-compressor isiqalile ukusebenza okuvamile, lungisa ivalvu elawula ukucindezela kukawoyela ukuze umehluko wokucindezela kukawoyela ube ngu-0.15 ~ 0.3MPa.
h. Hlola ukuthi ingcindezi kanye nokushisa kwengxenye ngayinye yemishini, ikakhulukazi izinga lokushisa lezingxenye ezihambayo, kujwayelekile yini. Uma kukhona okungajwayelekile, misa umshini ukuze uhlolwe.
i. Isikhathi sokuqala sokusebenza akufanele sibe side kakhulu, futhi umshini ungavalwa cishe ngesigamu sehora. Uchungechunge lokuvala luyathulula, lumise i-host, luvale i-valve yokuvala ukumunca, lumise iphampu kawoyela, futhi lumise iphampu yamanzi ukuze kuqedwe inqubo yokuqala yokuqalisa. Uma inkinobho yokumisa injini eyinhloko icindezelwa, i-valve ye-bypass solenoid B ivulwa ngokuzenzakalelayo, futhi i-valve B ivalwa ngokuzenzakalelayo ngemva kokuvala.
2. Ukuqalisa okujwayelekile kanye nokuvala
Ukuqala okuvamilekukhonaNgokulandelayo:
Khetha i-boot manual, inqubo iyafana ne-boot yokuqala.
Khetha ukuvula ngokuzenzakalelayo:
1) Vula ivalvu yokuvala i-compressor exhaust, qala iphampu yamanzi okupholisa kanye nephampu yamanzi efrijini;
2) Cindezela inkinobho yokuqala i-compressor, bese iphampu kawoyela izoqala ukusebenza ngokuzenzakalelayo, bese i-valve ye-spool izobuyela ngokuzenzakalelayo endaweni ethi “0”. Ngemva kokuthi umehluko wokucindezela kawoyela usuvele ukhona, imoto eyinhloko izoqala ngokuzenzakalelayo ngemva kokubambezeleka kwemizuzwana engaba ngu-15, bese i-valve ye-solenoid ye-bypass A izovuleka ngokuzenzakalelayo ngesikhathi esifanayo. Ngemva kokuthi imoto isebenze ngokujwayelekile, i-valve ye-A ivalwa ngokuzenzakalelayo;
3) Uma injini eyinhloko iqala ukuqala, ivalvu yokuvala ukumunca kufanele ivulwe kancane ngesikhathi esifanayo, ngaphandle kwalokho i-vacuum ephezulu kakhulu izokwandisa ukudlidliza nomsindo womshini.
4) I-compressor izokwandisa ngokuzenzakalelayo umthwalo ube ngu-100% futhi ingene esimweni esijwayelekile sokusebenza. Futhi ilungise ngokuzenzakalelayo indawo yomthwalo ngokuya ngenani lokusetha ingcindezi noma inani lokusetha izinga lokushisa le-refrigerant.
Inqubo evamile yokuvala i-alamu yilena elandelayo:
Ukuvala ngesandla kufana nenqubo yokuvala yokuqalisa kokuqala.
Iswishi yokukhetha isendaweni ezenzakalelayo:
1) Cindezela inkinobho yokumisa i-compressor, i-valve yesilayidi izobuyela ngokuzenzakalelayo endaweni ethi “0″, injini eyinhloko izoma ngokuzenzakalelayo, kanti i-valve ye-solenoid ye-bypass B izovula ngokuzenzakalelayo ngesikhathi esifanayo, iphampu kawoyela izoma ngokuzenzakalelayo ngemva kokubambezeleka, kanti i-valve ye-B izovala ngokuzenzakalelayo ngemva kokuma;
2) Vala ivalvu yokumisa ukumunca. Uma ivaliwe isikhathi eside, ivalvu yokuvala ugesi kufanele ivalwe;
3) Cima inkinobho yamandla yepompo yamanzi kanye ne-compressor.
3. Izinyathelo zokuphepha ngesikhathi sokusebenza
1) Qaphela ukubheka ingcindezi yokumunca nokukhipha, izinga lokushisa lokumunca nokukhipha, izinga lokushisa likawoyela nokucindezela kukawoyela ngesikhathi sokusebenza kwe-compressor, bese uqopha njalo. Imitha iyadingeka ukuze inembe.
2) I-compressor izoma ngokuzenzakalelayo ngenxa yesenzo esithile sokuvikela ukuphepha ngesikhathi sokusebenza kwe-compressor, futhi imbangela yokungasebenzi kahle kumele itholakale ngaphambi kokuba ivulwe. Ayivunyelwe ukuthi iphinde ivulwe ngokushintsha izilungiselelo zayo noma ukuvikela amaphutha.
3) Uma injini eyinhloko ivala ngenxa yokwehluleka kwamandla okungazelelwe, i-compressor ingase ibuyele emuva ngoba i-bypass solenoid valve B ayikwazi ukuvulwa. Ngalesi sikhathi, i-suction stop valve kufanele ivalwe ngokushesha ukuze kuncishiswe ukubuyela emuva.
4) Uma umshini uvaliwe isikhathi eside ngesikhathi sokushisa okuphansi, wonke amanzi ohlelweni kufanele akhishwe amanzi ukuze kugwenywe umonakalo obangelwa ukubanda kwemishini.
5) Uma uqala umshini ngesikhathi sokushisa okuphansi, qala uvule iphampu kawoyela, bese ucindezela injini ukuze ujikeleze isiteringi ukuze uhambise i-coupling ukuze wenze uwoyela ujikeleze ku-compressor ukuze uthole ukuthambisa okwanele. Le nqubo kumele yenziwe ngendlela yokuqalisa ngesandla; uma kuyi-Freon refrigerant, qala umshini Ngaphambi kokuvula i-oyela heater ukuze ufudumale uwoyela wokugcoba, izinga lokushisa likawoyela kumele libe ngaphezu kwama-25℃.
6) Uma iyunithi ivaliwe isikhathi eside, iphampu kawoyela kufanele ivulwe njalo ezinsukwini eziyi-10 noma ngaphezulu ukuqinisekisa ukuthi kukhona uwoyela wokugcoba kuzo zonke izingxenye ze-compressor. Isikhathi ngasinye iphampu kawoyela ivulwa imizuzu eyi-10; i-compressor ivulwa kanye njalo ezinyangeni ezi-2 kuya kwezi-3, njalo ngehora eli-1. Qinisekisa ukuthi izingxenye ezihambayo azinamatheli ndawonye.
7) Ngaphambi kokuqala isikhathi ngasinye, kungcono ukujikelezisa i-compressor izikhathi ezimbalwa ukuze uhlole ukuthi i-compressor ivaliwe noma cha, bese usabalalisa uwoyela wokugcoba ngokulinganayo kuzo zonke izingxenye.
