1. Ukuqala Kokuqala Nokuvala
Ngaphambi kokuqala umshini, ukuxhumanisa kumele kuhlelwe kabusha. Ngaphambi kokuqala umshini okokuqala, hlola ukusebenza kwazo zonke izingxenye ze-compressor kanye nezingxenye zikagesi.
Izinto zokuhlola zimi kanje:
Vula inkinobho yokuvula bese usetha inkinobho yokukhetha endaweni yokwenziwa ngesandla;
Cindezela inkinobho ye-alamu; i-alamu izokhala; cindezela inkinobho yokuthulisa; i-alamu izokhala;
Cindezela inkinobho yesifudumezi sikagesi; isibani senkomba sizokhanya. Ngemva kokuqinisekisa ukuthi isifudumezi sikagesi siyasebenza, cindezela inkinobho yokumisa ukushisa; isibani senkomba yokushisa sizocima;
Cindezela inkinobho yokuqalisa iphampu yamanzi; iphampu yamanzi iyaqala; isibani senkomba sizokhanya. Cindezela inkinobho yokuvala iphampu yamanzi; iphampu yamanzi iyayeka; isibani senkomba sizocima;
Cindezela inkinobho yokuqala yepompo kawoyela; isibani sesikhombisi sepompo kawoyela sizokhanya, futhi ipompo kawoyela isebenza futhi ijikeleza ngendlela efanele. Lungisa umehluko wokucindezela kawoyela ube ngu-0.4-0.6 MPa.
Hambisa ivalvu enezindlela ezine noma cindezela inkinobho yokwandisa/ukwehlisa umthwalo ukuze uhlole ukuthi ivalvu yesilayidi kanye nesibonakaliso samandla kusebenza kahle. Isibonakaliso sezinga lamandla kufanele sibe ku-“0.” Hlola izilungiselelo zazo zonke izinhlelo zokuphepha ezizenzakalelayo noma ama-relay.
Ukuvikelwa okuphezulu komfutho wokukhipha ugesi: Umfutho wokukhipha ugesi ≤ 1.57 MPa
Izinga lokushisa lomjovo ukuvikelwa okuphezulu: Izinga lokushisa lomjovo ≤ 65°C
Umehluko wokucindezela kukawoyela ukuvikelwa okuphansi: Umehluko wokucindezela kukawoyela ≥ 0.1 MPa
Ukuvikelwa okuphezulu komehluko wokucindezela ngaphambi nangemva kwesihlungi esincane: Umehluko wokucindezela ≤ 0.1 MPa
Ukuvikelwa okuphansi komfutho wokungenisa: Kusethwe ngokwezimo zokusebenza zangempela.
Ngemva kokuhlola izinto ezingenhla, iyunithi ingaqalwa. Izinyathelo zokuqala zimi kanje:
1) Khetha inkinobho yokuqalisa ngesandla.
2) Vula ivalvu yokuvala yokukhipha i-compressor.
3) Layisha i-compressor iye endaweni ethi “0″, okungukuthi, umthwalo ongu-10%.
4) Qala iphampu yamanzi okupholisa kanye nephampu yamanzi esiqandisini ukuze unikeze amanzi ku-condenser, ku-oyela cooler, kanye ne-evaporator.
5) Qala ipompo kawoyela.
6) Imizuzwana engama-30 ngemuva kokuqala kwephampu kawoyela, futhi umehluko wengcindezi kawoyela phakathi kwengcindezi kawoyela kanye nengcindezi yokukhipha ugesi ufinyelela ku-0.4-0.6 MPa, cindezela inkinobho yokuqala ye-compressor. I-compressor izoqala, bese i-pass solenoid valve A izovuleka ngokuzenzakalelayo. Ngemva kokuba imoto isebenza kahle, i-valve A izovala ngokuzenzakalelayo.
7) Qaphela igeyiji yokucindezela kokumunca, vula kancane kancane ivalvu yokuvala ukumunca, bese ukhuphula umthwalo ngesandla, uqaphela ukuthi ingcindezi yokumunca ayinciphi kakhulu. Ngemva kokuba i-compressor isiqalile ukusebenza okuvamile, lungisa ivalvu elawula ukucindezela kukawoyela ukuze ugcine ingcindezi kawoyela ehlukile engu-0.15-0.3 MPa.
8) Hlola ingcindezi kanye nokushisa kwazo zonke izingxenye zemishini, ikakhulukazi lezo zezingxenye ezihambayo, ukuze zisebenze ngendlela evamile. Uma kutholakala noma yikuphi ukungahambi kahle, vala imishini ukuze ihlolwe.
9) Ukusebenza kokuqala akufanele kube isikhathi eside kakhulu; cishe isigamu sehora sanele. Uchungechunge lokuvala ilokukhipha imishini, ukuvala injini eyinhloko, ukuvala ivalvu yokuvala ukumunca, ukuvala iphampu kawoyela, bese uvala iphampu yamanzi, ukuqeda inqubo yokuqala yokuqalisa. Ukucindezela inkinobho yokumisa injini eyinhloko kuvula ngokuzenzakalelayo ivalvu ye-bypass solenoid B. Ivalvu B ivala ngokuzenzakalelayo ngemva kokuvala ivalvu.
2. Ukuqalisa Okujwayelekile Nokuvala: Inqubo evamile yokuqalisa ilandelayo:
a. Khetha ukuqalisa ngesandla, okufana nenqubo yokuqala yokuqalisa.
b. Khetha ukuqala okuzenzakalelayo
1) Vula ivalvu yokuvala i-compressor exhaust bese uqala iphampu yamanzi okupholisa kanye nephampu yesiqandisi. 2) Cindezela inkinobho yokuqala i-compressor. Iphampu kawoyela izoqala ukusebenza ngokuzenzakalelayo kanti ivalvu yesilayidi izobuyela ngokuzenzakalelayo endaweni ethi “0”. Ngemva kokuthi umehluko wokucindezela kawoyela usumisiwe, imoto eyinhloko izoqala ngokuzenzakalelayo ngemva kokubambezeleka okungaba yimizuzwana eyi-15, bese ivalvu ye-bypass solenoid A izovula ngokuzenzakalelayo. Uma imoto isebenza ngokujwayelekile, ivalvu A izovala ngokuzenzakalelayo. 3) Lapho imoto eyinhloko iqala, vula kancane ivalvu yokuvala i-suction ngasikhathi sinye. Ngaphandle kwalokho, i-vacuum eningi izokwandisa ukudlidliza nomsindo womshini. 4) I-compressor izokhulisa ngokuzenzakalelayo umthwalo ube yi-100% futhi ingene ekusebenzeni okuvamile. Indawo yokulayisha izozilungisa ngokuzenzakalelayo ngokuya nge-setpoint yokucindezela noma i-setpoint yokushisa yesiqandisi.
Inqubo evamile yokuvala ivaliwe yile: a. Ukuvala ngesandla: Kufana nenqubo yokuqala yokuqalisa. b. Uma iswishi yokukhetha isendaweni ezenzakalelayo: 1) Cindezela inkinobho yokumisa i-compressor. I-valve yesilayidi ibuyela ngokuzenzakalelayo endaweni ethi “0″, imoto eyinhloko iyama ngokuzenzakalelayo, bese i-valve ye-solenoid ye-bypass B ivuleka ngokuzenzakalelayo. Iphampu kawoyela iyama ngokuzenzakalelayo ngemva kokulibaziseka. Ngemva kokuvala, i-valve B iyavala ngokuzenzakalelayo. 2) Vala i-valve yokumisa ukumunca. Uma umshini uvaliwe isikhathi eside, i-valve yokumisa ukukhishwa kwegesi kufanele ivalwe. 3) Vala amandla ephampu yamanzi kanye nezinkinobho zamandla e-compressor.
3. Izinyathelo zokuphepha ngesikhathi sokusebenza
(1) Ngesikhathi sokusebenza kwe-compressor, qaphela ukubheka ingcindezi yokumunca kanye neyokukhipha, izinga lokushisa lokumunca kanye neyokukhipha, izinga lokushisa likawoyela kanye nengcindezi kawoyela, bese uqopha njalo. Ithuluzi kumele libe nembambo.
(2) Uma i-compressor izima ngokuzenzakalelayo ngenxa yesenzo sokuvikela ukuphepha ngesikhathi sokusebenza, imbangela yephutha kumele itholakale ngaphambi kokuthi iqale kabusha. Akuvunyelwe ukuqala kabusha ngokushintsha amanani ayo asethiwe noma ukuvikela iphutha.
(3) Uma iyunithi eyinhloko ima ngenxa yokuphazamiseka kukagesi okungazelelwe, i-bypass solenoid valve B ayikwazi ukuvulwa, futhi i-compressor ingase ibuyele emuva. Ngalesi sikhathi, i-suction stop valve kufanele ivalwe ngokushesha ukuze kuncishiswe ukubuyela emuva.
(4) Uma umshini uvaliwe isikhathi eside ngesizini enokushisa okuphansi, wonke amanzi ohlelweni kufanele akhishwe amanzi ukuze kugwenywe umonakalo obangelwa ukubanda kwemishini.
(5) Uma umshini uqalwa ngesizini enokushisa okuphansi, qala uqale iphampu kawoyela bese ucindezela injini ukuze ujikeleze isiteringi ukuze uhambise i-coupling ukuze uwoyela ujikeleze ku-compressor ukuze uthole ukuthambisa okwanele. Le nqubo kumele yenziwe ngendlela yokuqalisa ngesandla; uma kuyi-Freon refrigerant, i-oyela heater kufanele ivulwe ukuze kushiswe uwoyela wokugcoba ngaphambi kokuqala umshini, futhi izinga lokushisa likawoyela kufanele liqinisekiswe ukuthi lingaphezu kuka-25℃.
(6) Uma iyunithi ivaliwe isikhathi eside, ipompo yamafutha kufanele iqalwe njalo ezinsukwini eziyi-10 noma ngaphezulu ukuqinisekisa ukuthi zonke izingxenye zecompressor zigcotshwe ngamafutha. Ipompo yamafutha ingaqalwa imizuzu eyi-10 njalo. Icompressor kufanele iqalwe njalo ezinyangeni ezi-2 kuya kwezi-3 isikhathi esiyihora eli-1 njalo ukuqinisekisa ukuthi izingxenye ezihambayo azinamatheli ndawonye.
(7) Ngaphambi kokuqala iyunithi isikhathi ngasinye, kungcono ukujikelezisa i-compressor izikhathi eziningana ukuze uhlole ukuthi i-compressor inamathele yini futhi uqinisekise ukuthi uwoyela wokugcoba usatshalaliswa ngokulinganayo kuzo zonke izingxenye.
Isikhathi sokuthunyelwe: Okthoba-22-2025
