1. Ukuhlolwa phambi kokuqala i Itonela axial flow fan (inyathelo elingundoqo)
1. Ukukhangela ubume besixhobo:
– Qinisekisa ukuba i-impeller ye-fan ayivalwanga, ii-blades azonakaliswa, i-air duct ayivalwanga, kwaye i-bolts yokudibanisa igxininiswe.
- Khangela ukuba ngaba ii-circuit breakers kunye neebhloko ze-terminal ngaphakathi kwekhabhinethi yokuqala yokuguqulwa kwe-frequency ikhululekile, kwaye uqinisekise ukuba umnyango wekhabhinethi uvalwe ngokuqinileyo ngaphandle kwezinto zangaphandle okanye ukuqokelela kwamanzi.
2. Amalungiselelo okhuseleko:
- Qinisekisa ukuba akukho basebenzi abasebenza kwindawo yokusebenza, i-fan outlet ayivalwanga, kwaye uxhome uphawu lwesilumkiso "Ukuqala ngokuqhubekayo, qaphela ukhuseleko" (ukuba kuyimfuneko).
– Abaqhubi kufuneka baqinisekise ukuba baqhelene nendawo yeqhosha lokumisa kwimeko yongxamiseko.
II. Unikezelo lwaMandla oMbane kwiKhabhinethi yoLawulo lweTunnel Axial Fan
1. Vula iswitshi yamandla engundoqo:
-Khangela i-breaker circuit yamandla engundoqo (utshintsho oluphambili) ngaphakathi kwekhabhinethi. Jikelezisa isiphatho ukusuka ku-"OFF" ukuya ku-"ON", kwaye uve isandi esithi "cofa" phambi kokuba usitshixe. Ngeli xesha, ukukhanya kwesalathisi samandla (njenge "Indicator Power") kuya kukhanya.
2. Vula isitshixo samandla solawulo:
- Vala i-breaker circuit breaker (i-breaker circuit breaker okanye i-knob), kwaye uyihambise kwindawo ethi "ON". Isiphaluka solawulo sinikwe amandla, kwaye amaqhosha epaneli yokusebenza kunye nomboniso (ukuba kukho) kuya kwenziwa.
III. I-Tunnel Axial Fan Useto lweMowudi (Khetha ngokweemfuno)
Ikhabhinethi yokuqalisa ukuguqulwa kwamaza kaninzi ineendlela ezinje nge "manual yendawo" kunye "nolawulo olukude". Ngaphambi kokuba uqale, kufuneka uqinisekise imowudi:
-Imowudi yeManuwali yaseKhaya (Ukusebenza kwisiza):
Tshintsha iswitsha yokukhetha imo (efana neqhosha elithi “Local/Remote”) ukuya ku-“Local” okanye “Manual”. Kweli nqanaba, ungalawula ngokuthe ngqo ngamaqhosha akwisiza.
-Imo yokulawula ukude (Lawula ngoMqondiso wangaphandle):
Ukuba ufuna ukuyiqala nge-PLC okanye inkqubo yolawulo ephakathi, tshintshela kwi-"Remote". Ukuqala kuya kubangelwa ngumqondiso wangaphandle (qiniseka ukuba uphawu olukude luqhelekile ngaphambi kokuba uqhubeke).
Qala ifeni
(1) Isiqalo sesandla salapha (esona sisetyenziswa kakhulu)
1. Cofa iqhosha elithi "Qala":
Cinezela iqhosha eliluhlaza "Qala (QALA)" kwiphaneli yekhabhinethi. Isiguquli esijikelezayo siqala ukukhupha i-voltage, kwaye i-motor iqhuba i-fan ukuba iqale ngokucothayo (isiqalo esithambileyo ngokuguqulwa kwamaza, isantya sinyuka ngokuthe ngcembe ukusuka ku-0).
- Ngexesha lenkqubo yokuqalisa, jonga umboniso (ukuba kukho): i-frequency inyuka ngokuthe ngcembe ukusuka kwixabiso lokuqala (elifana ne-0 Hz), kwaye isantya sikwanyuka ngokuhambelanayo, kungekho ngxolo engaqhelekanga.
-Ukuba isiqalo asiphumeleli (ikhowudi yempazamo ibonakala kwiphaneli yokubonisa isiguquli), ngokukhawuleza cofa iqhosha elithi "Yeka", kwaye ujonge ukugcwala, ukulahleka kwesigaba, okanye iimpazamo zemoto ngaphambi kokuba uzame kwakhona.
2. Qinisekisa isantya sokuqala:
Emva kokuqalisa, ifeni iyasilela ekusebenzeni kwifrikhwensi yokuqala (efana ne-50 Hz okanye ubuncinci obusetwe kwangaphambili), okanye igcina isantya phambi kokuvalwa kokugqibela. Unokujonga imeko yangoku usebenzisa imitha yesantya okanye imitha yobuninzi.
(2) Ukulawulwa kwesantya sokusebenza kwetonela ye-axial flow fan frequency conversion control cabinet (ukuba ufuna ukulungisa umthamo womoya)
1. Uhlengahlengiso lwesantya:
Cofa iqhosha elithi “Ukukhawulezisa (ACCEL)” okanye utolo oluya phezulu. I-frequency inyuka ngokuthe ngcembe (umzekelo ukusuka kwi-30Hz ukuya kwi-50Hz), isantya sokujikeleza sikhuphuka, umthamo womoya uyanda. Khupha iqhosha ukutshixa isantya sangoku sokujikeleza.
2. ULungiselelo lokunciphisa:
Cofa iqhosha elithi "Deceleration (DECEL)" okanye iqhosha elisezantsi. I-frequency iyancipha (umzekelo ukusuka kwi-50Hz ukuya kwi-20Hz), isantya sokujikeleza siyancipha, umthamo womoya uyancipha. Khupha kwaye ugcine isantya sangoku sokujikeleza.
3. Qaphela:
– Uhlengahlengiso lwesantya kufuneka lwenziwe ngokucothayo. Uluhlu olulodwa lohlengahlengiso alufanele lube lukhulu kakhulu (umzekelo, ukwanda okanye ukunciphisa nge-5Hz ngexesha ngalinye). Kuphephe ukungcangcazela kwefeni okanye ukugcwala kwemoto.
– Umda osezantsi wesantya sokujikeleza ukhawulelwe ziiparamitha zomguquli wefrequency (ngokuqhelekileyo awukho ngaphantsi kwe-10-15Hz). Isantya esisezantsi kakhulu esijikelezayo sinokubangela ukukhutshwa kobushushu obungalunganga benjini.
Xa uqalisa umgodi-usebenzisa i-counter-rotation fan, indlela yokujikeleza ye-fan impeller kufuneka ihambelane notolo kwizindlu zefeni. Xa ii-motor ezimbini ziqala ngaxeshanye, ikhefu akufanele lidlule imizuzwana engama-30. Iinjini ezimbini kufuneka zisebenze ngesantya esifanayo. Nayiphi na inokuqalwa kwaye isebenze ngokuzimeleyo.
