1. Ukuhlola ngaphambi kokuqala uhlelo Umhubhe we-axial flow fan (isinyathelo esibalulekile)
1. Ukuhlola isimo sezisetshenziswa:
- Qinisekisa ukuthi i-impeller ye-fan ayivinjiwe, ama-blades awawonakali, i-air duct ayivaliwe, futhi ama-bolts axhunyiwe aqinisiwe.
- Hlola ukuthi ama-circuit breaker nama-terminal blocks ngaphakathi kwekhabhinethi yokuqala yokuguqulwa kwe-frequency akhululekile yini, futhi uqinisekise ukuthi umnyango wekhabethe uvalwe ngokuqinile ngaphandle kwezinto zangaphandle noma ukunqwabelana kwamanzi.
2. Amalungiselelo okuphepha:
- Qinisekisa ukuthi abekho abasebenzi abasebenza endaweni yokusebenza, indawo yokukhipha abalandeli ayivinjwanga, futhi ulengise uphawu oluyisixwayiso “Ukuqala okuqhubekayo, qaphela ukuphepha” (uma kunesidingo).
- Abasebenzi badinga ukuqinisekisa ukuthi bayayazi indawo yenkinobho yokumisa uma kwenzeka isimo esiphuthumayo.
II. Umsebenzi Wokuhlinzeka Amandla Wekhabhinethi Yokulawula Abalandeli Be-Tunnel Axial
1. Vula iswishi yamandla eyinhloko:
- Thola i-breaker circuit yamandla eyinhloko (i-switch enkulu) ngaphakathi kwekhabhinethi. Zungezisa isibambo sisuke kokuthi “VALIWE” siye kokuthi “VULIWE”, bese uzwa umsindo othi “chofoza” ngaphambi kokusikhiya. Kuleli qophelo, ukukhanya okukhulu kwenkomba yamandla (njengokuthi "Isikhombi Samandla") kuzokhanya.
2. Vula iswishi yamandla okulawula:
- Vala i-circuit breaker (i-breaker circuit encane noma i-knob), bese uyihambisa endaweni ethi "ON". Isifunda sokulawula sinikwe amandla, futhi izinkinobho zephaneli yokusebenza nesibonisi (uma sikhona) sizosebenza.
III. Izilungiselelo ze-Tunnel Axial Fan Mode (Khetha ngokwezidingo)
Ikhabhinethi yokuqala yokuguqulwa kwemvamisa ivamise ukuba namamodi afana “nemanuwali yendawo” kanye “nokulawula kude”. Ngaphambi kokuqala, kuyadingeka ukuthi uqinisekise imodi:
- Imodi Yemanuwali Yasendaweni (Ukusebenza esizeni):
Shintsha iswishi yokukhetha imodi (njengenkinobho ethi “Local/Remote”) iye kokuthi “Local” noma “Manual”. Kuleli qophelo, ungakwazi ukuyilawula ngokuqondile ngezinkinobho ezikusayithi.
- Imodi yokulawula kude (Lawula Ngesiginali yangaphandle):
Uma udinga ukuyiqala nge-PLC noma ngesistimu yokulawula emaphakathi, shintshela kokuthi “Remote”. Ukuqala kuzoqaliswa isignali yangaphandle (qiniseka ukuthi isignali yesilawuli kude ijwayelekile ngaphambi kokuqhubeka).
Qala ifeni
(1) Ukuqaliswa kwendawo okwenziwa ngesandla (okuvame ukusetshenziswa kakhulu)
1. Cindezela inkinobho ethi “Qala”:
Cindezela inkinobho eluhlaza "Qala (QALA)" kuphaneli yekhabhinethi. Isiguquli sefrikhwensi siqala ukukhipha i-voltage, futhi i-motor ishayela fan ukuthi iqale kancane (isiqalo esithambile ngokuguqulwa kwemvamisa, isivinini sikhuphuka kancane sisuka ku-0).
– Ngesikhathi senqubo yokuqalisa, bheka isibonisi (uma sikhona): imvamisa inyuka kancane kancane ukusuka enanini lokuqala (elifana no-0 Hz), futhi isivinini sikhuphuka ngokuhambisanayo, ngaphandle komsindo ongajwayelekile.
- Uma isiqalo sihluleka (ikhodi yephutha ivela kuphaneli yokubonisa i-frequency converter), cindezela ngokushesha inkinobho ethi "Misa", bese uhlola ukugcwala okugcwele, ukulahleka kwesigaba, noma amaphutha emoto ngaphambi kokuzama futhi.
2. Qinisekisa isivinini sokuqala:
Ngemva kokuqala, ifeni ishintsha ngokuzenzakalelayo ukuthi isebenze kumafrikhwensi okuqala (njengo-50 Hz noma ubuncane befrikhwensi emisiwe), noma igcina isivinini ngaphambi kokuvalwa kokugcina. Ungakwazi ukubona isimo samanje usebenzisa imitha yesivinini noma imitha yefrikhwensi.
(2) Ukusebenza kokulawula isivinini kwekhabhinethi yokulawula ukuguqulwa kwe-axial flow fan frequency conversion (uma udinga ukulungisa ivolumu yomoya)
1. Ukulungiswa Kwesivinini:
Cindezela inkinobho ethi “Acceleration (ACCEL)” noma ukhiye womcibisholo oya phezulu. Imvamisa iyanda kancane kancane (isb. isuka ku-30Hz iye ku-50Hz), ijubane lokujikeleza liyakhuphuka, ivolumu yomoya iyanda. Dedela inkinobho ukuze ukhiye isivinini samanje sokujikeleza.
2. Ukulungiswa Kokunciphisa:
Cindezela inkinobho ethi “Deceleration (DECEL)” noma ukhiye womcibisholo oya phansi. Imvamisa iyancipha (isb. ukusuka ku-50Hz ukuya ku-20Hz), isivinini sokujikeleza siyancipha, umthamo womoya uyancipha. Khulula futhi ugcine isivinini samanje sokujikeleza.
3. Qaphela:
- Ukulungiswa kwesivinini kufanele kwenziwe kancane. Ububanzi bokulungisa okukodwa akufanele bube bukhulu kakhulu (isb. ukwanda noma ukunciphisa ngo-5Hz isikhathi ngasinye). Gwema ukudlidliza kwabalandeli noma ukugcwala kwemoto.
- Umkhawulo ophansi wejubane lokujikeleza unqunyelwe amapharamitha wesiguquli semvamisa (ngokuvamile awekho ngaphansi kuka-10-15Hz). Ijubane eliphansi kakhulu lokuzungeza lingabangela ukungashisi kahle kwenjini.
Uma uqalisa ifeni ephendukisayo yokusebenzisa imayini, isiqondiso sokuzungezisa se-impeller kufanele sihambisane nomcibisholo osendaweni yabalandeli. Lapho izinjini ezimbili ziqala kanyekanye, isikhawu akufanele sidlule imizuzwana engama-30. Amamotho amabili kufanele asebenze ngesivinini esifanayo. Noma iyiphi ingaqalwa futhi isebenze ngokuzimela.
