1. Ukuqalisa kokuqala kunye nokuvala
Ngaphambi kokuba umatshini uqale, i-coupling kufuneka ilungelelaniswe. Ngaphambi kokuba umatshini uqale okokuqala, jonga ukusebenza kwazo zonke iindawo ze-compressor kunye nezixhobo zombane.
Izinto zokuhlola zezi zilandelayo:
Vula iswitshi yombane uze usete iswitshi yokukhetha kwindawo yesandla;
Cinezela iqhosha le-alamu; i-alamu iya kukhala; cofa iqhosha lokungathethi; i-alamu iya kukhala;
Cinezela iqhosha lesifudumezi sombane; isibane sesalathisi siya kukhanyisa. Emva kokuqinisekisa ukuba isifudumezi sombane siyasebenza, cofa iqhosha lokumisa ukufudumeza; isibane sesibonakaliso sokufudumeza siya kucima;
Cinezela iqhosha lokuqalisa ipompo yamanzi; ipompo yamanzi iyaqala; isibane sesalathisi siya kukhanyisa. Cinezela iqhosha lokuyeka ipompo yamanzi; ipompo yamanzi iyayeka; isibane sesalathisi siya kucima;
Cinezela iqhosha lokuqalisa ipompo yeoyile; isibane sesalathisi sepompo yeoyile siya kukhanyisa, kwaye ipompo yeoyile isebenza kwaye ijikeleza kwicala elifanelekileyo. Lungisa umahluko woxinzelelo lweoyile ube yi-0.4-0.6 MPa.
Hambisa ivalvu eneendlela ezine okanye ucinezele iqhosha lokunyusa/ukunciphisa umthwalo ukuze ujonge ukuba ivalvu yesilayidi kunye nesalathisi samandla zisebenza ngokufanelekileyo na. Isalathisi senqanaba lamandla kufuneka sibe ku-“0.” Jonga useto lwazo zonke iireyi zokhuseleko ezizenzekelayo okanye iinkqubo.
Ukhuseleko oluphezulu loxinzelelo lokukhupha umoya: Uxinzelelo lokukhupha umoya ≤ 1.57 MPa
Ubushushu bokujova bukhuselekile kakhulu: Ubushushu bokujova ≤ 65°C
Umahluko woxinzelelo lweoyile ukhuseleko oluphantsi: Umahluko woxinzelelo lweoyile ≥ 0.1 MPa
Ukhuseleko oluphezulu lomahluko woxinzelelo ngaphambi nasemva kwesihluzo esincinci: Umahluko woxinzelelo ≤ 0.1 MPa
Ukhuseleko oluphantsi loxinzelelo lokungenisa: Lusetwe ngokweemeko zokusebenza zangempela.
Emva kokujonga ezi zinto zingasentla, iyunithi ingaqaliswa. Amanyathelo okuqalisa ngala alandelayo:
1) Khetha iswitshi yokuqalisa ngesandla.
2) Vula ivalvu yokuvala i-compressor discharge.
3) Khupha icompressor kwindawo ethi “0″, oko kukuthi, umthwalo we-10%.
4) Qalisa ipompo yamanzi okupholisa kunye nepompo yamanzi efrijini ukuze unike amanzi kwi-condenser, kwi-oyile cooler, nakwi-evaporator.
5) Qalisa ipompo yeoyile.
6) Emva kwemizuzwana engama-30 ipompo yeoyile iqalile, kwaye umahluko woxinzelelo yeoyile phakathi koxinzelelo yeoyile kunye noxinzelelo lokukhupha umoya ufikelela kwi-0.4-0.6 MPa, cofa iqhosha lokuqalisa icompressor. Icompressor iya kuqala, kwaye i-pass solenoid valve A iya kuvula ngokuzenzekelayo. Emva kokuba imoto isebenza ngokuqhelekileyo, ivalvu A iya kuvala ngokuzenzekelayo.
7) Jonga igeyiji yoxinzelelo lokufunxa, vula kancinci ivalvu yokuvala ukufunxa, uze wonyuse umthwalo ngesandla, uqaphele ukuba uxinzelelo lokufunxa aluwi phantsi kakhulu. Emva kokuba icompressor isebenze ngendlela eqhelekileyo, lungisa ivalvu elawula uxinzelelo lweoyile ukuze ugcine uxinzelelo lweoyile oluhlukileyo lwe-0.15-0.3 MPa.
8) Jonga uxinzelelo kunye nobushushu bazo zonke iindawo zezixhobo, ingakumbi ezo zeendawo ezihambayo, ukuze zisebenze ngendlela eqhelekileyo. Ukuba kukho into engaqhelekanga efunyenweyo, vala izixhobo ukuze zihlolwe.
9) Umsebenzi wokuqala akufuneki ube mde kakhulu; malunga nesiqingatha seyure sanele. Ulandelelwano lokuvala kukukhulula izixhobo, ukuvala injini ephambili, ukuvala ivalvu yokuvala ukufunxa, ukuvala ipompo yeoyile, uze umise ipompo yamanzi, ugqibezele inkqubo yokuqala yokuqalisa. Ukucinezela iqhosha lokumisa injini ephambili kuvula ngokuzenzekelayo ivalvu ye-bypass solenoid B. Ivalvu B ivala ngokuzenzekelayo emva kokuvala.
2. Ukuqalisa Okuqhelekileyo kunye nokuCima: Inkqubo eqhelekileyo yokuqalisa imi ngolu hlobo lulandelayo:
a. Khetha uqaliso oluqhutywa ngesandla, olufana nenkqubo yokuqala yoqaliso.
b. Khetha ukuqalisa ngokuzenzekelayo
1) Vula ivalvu yokuvala i-compressor exhaust uze uqalise ipompo yamanzi okupholisa kunye nepompo yefriji. 2) Cinezela iqhosha lokuqalisa i-compressor. Ipompo yeoyile iya kuqala ukusebenza ngokuzenzekelayo kwaye ivalvu yesilayidi iya kubuyela ngokuzenzekelayo kwindawo ethi "0". Emva kokuba umahluko woxinzelelo lweoyile usekiwe, i-motor ephambili iya kuqala ngokuzenzekelayo emva kokulibaziseka malunga nemizuzwana eli-15, kwaye ivalvu ye-bypass solenoid A iya kuvula ngokuzenzekelayo. Nje ukuba i-motor isebenze ngokwesiqhelo, ivalvu A iya kuvala ngokuzenzekelayo. 3) Xa i-motor ephambili iqala, vula kancinci ivalvu yokuvala i-suction ngaxeshanye. Ngaphandle koko, i-vacuum eninzi iya kwandisa ukungcangcazela kunye nengxolo yomatshini. 4) I-compressor iya kunyusa ngokuzenzekelayo umthwalo uye kwi-100% kwaye ingene ekusebenzeni okuqhelekileyo. Indawo yomthwalo iya kulungelelanisa ngokuzenzekelayo ngokwendawo yokubeka uxinzelelo okanye indawo yokubeka ubushushu befriji.
Inkqubo eqhelekileyo yokuvala intsimbi yile ilandelayo: a. Ukuvala ngesandla: Kuyafana nenkqubo yokuqala yokuqalisa. b. Xa iswitshi yokukhetha ikwindawo ezenzekelayo: 1) Cinezela iqhosha lokumisa icompressor. Ivalvu yesilayidi ibuyela ngokuzenzekelayo kwindawo ethi “0″, imotor ephambili iyama ngokuzenzekelayo, kwaye ivalvu ye-B edlulayo iyavula ngokuzenzekelayo. Ipompo yeoyile iyama ngokuzenzekelayo emva kokulibaziseka. Emva kokuvala, ivalvu B iyavala ngokuzenzekelayo. 2) Vala ivalvu yokumisa ukufunxa. Ukuba umatshini uvaliwe ixesha elide, ivalvu yokumisa umbane kufuneka ivalwe. 3) Cima amandla epompo yamanzi kunye neeswitshi zamandla ecompressor.
3. Amanyathelo okhuseleko ngexesha lokusebenza
(1) Ngexesha lokusebenza kwecompressor, qaphela ukuba ingakanani na i-suction kunye ne-exhaust pressure, i-suction kunye ne-exhaust temperature, i-oyile kunye ne-oyile pressure, kwaye uyirekhode rhoqo. Isixhobo kufuneka sichaneke.
(2) Ukuba icompressor iyeka ngokuzenzekelayo ngenxa yesenzo sokhuseleko ngexesha lokusebenza, unobangela wempazamo kufuneka ufunyanwe ngaphambi kokuba iqalwe kwakhona. Ayivumelekanga ukuba iqalwe kwakhona ngokutshintsha amaxabiso ayo amiselweyo okanye ngokukhusela impazamo.
(3) Xa iyunithi ephambili ima ngenxa yokucima kombane ngequbuliso, ivalvu ye-solenoid ye-bypass B ayinakuvulwa, kwaye i-compressor inokubuyela umva. Ngeli xesha, ivalvu yokumisa ukufunxa kufuneka ivalwe ngokukhawuleza ukuze kuncitshiswe umva.
(4) Ukuba umatshini uvaliwe ixesha elide kwixesha lonyaka apho ubushushu buphantsi, onke amanzi akwinkqubo kufuneka akhutshwe amanzi ukuze kuthintelwe ukonakala kwezixhobo.
(5) Ukuba umatshini uqalwa ngexesha lobushushu obuphantsi, qala uqalise ipompo yeoyile uze ucinezele i-motor ukuze ijikelezise ivili lokuqhuba ukuze ihambise i-coupling ukuze ioyile ijikeleze kwi-compressor ukuze i-lubricate eyaneleyo. Le nkqubo kufuneka yenziwe ngendlela yokuqalisa ngesandla; ukuba yi-Freon refrigerant, i-oyile heater kufuneka ivulwe ukuze ifudumale ioyile yokuthambisa ngaphambi kokuba umatshini uqale, kwaye ubushushu beoyile kufuneka buqinisekiswe ukuba bungaphezulu kwama-25℃.
(6) Ukuba iyunithi ivaliwe ixesha elide, ipompo yeoyile kufuneka iqaliswe rhoqo emva kweentsuku ezili-10 okanye ngaphezulu ukuqinisekisa ukuba zonke iindawo zecompressor zithanjiswe ngeoyile. Ipompo yeoyile ingaqaliswa imizuzu eli-10 rhoqo. Icompressor kufuneka iqaliswe rhoqo emva kweenyanga ezi-2 ukuya kwezi-3 kangangeyure e-1 rhoqo ukuqinisekisa ukuba iindawo ezihambayo azinamatheli.
(7) Ngaphambi kokuba uqalise iyunithi ngalo lonke ixesha, kungcono ujikeleze icompressor izihlandlo ezininzi ukujonga ukuba icompressor ibambekile na kwaye uqinisekise ukuba ioyile yokuthambisa isasazwe ngokulinganayo kuzo zonke iindawo.
