I. Izimiso Zokusebenza Zokuphepha Eziyinhloko
- Ngaphambi kokusebenza, kubalulekile ukuqinisekisa ukuthi ukuvikelwa komuntu kuyasebenza. Gqoka amagilavu avaliwe kanye nezicathulo zokusebenza ezilwa nokushelela. Izinwele ezinde kufanele ziboshwe. Izimpahla ezixegayo noma ubucwebe abuvunyelwe ngokuqinile ukuvimbela ukugoqa ezingxenyeni ezijikelezayo.
Ngaphambi kokuqala, indawo yokusebenza kufanele isulwe, futhi uphawu oluyisixwayiso oluthi “Imishini eqalayo, akukho kungena” kufanele kumiswe ukuze kuqinisekiswe ukuthi izisebenzi ezingabalulekile ziyathutha ziye endaweni ephephile, zigweme ukulimala okubangelwa umthelela wokugeleza komoya noma ukuhlukaniswa kwengxenye.
Yonke imisebenzi kufanele yenziwe ngabasebenzi abaqinisekisiwe abathole ukuqeqeshwa okukhethekile. Abangebona ochwepheshe banqatshelwe ngokuphelele ukuthinta amaswishi ekhabhinethi yokulawula, izintambo zemoto, nezingxenye ezijikelezayo zefeni. Ngesikhathi sokulungiswa, inqubo "yokucima - ukuvala ithegi" kufanele ilandelwe ngokuqinile.
Esimeni sanoma yisiphi isimo esiphuthumayo phakathi nenqubo yokuqalisa (njengokungena kwabasebenzi abangagunyaziwe noma umsindo omkhulu ongajwayelekile ovela emshinini), cindezela ngokushesha inkinobho ethi “Emergency Stop” kukhabhinethi yokulawula ukuze unqamule ukunikezwa kwamandla, bese uqhubeke nokuphatha okulandelayo. Akuvunyelwe ngokuphelele ukuphazamisa ngokuqondile okokusebenza ngenkathi isebenza.
II. Izinyathelo Ezikhethekile Zokuqala Ukusebenza
I-axial flow fan yakhelwe ngesici esithi "no-load start". Ipayipi lomoya elivaliwe lizobangela ukwanda okungazelelwe kokumelana nokugeleza komoya, okuholela ekulayisheni kwemoto nokukhubeka. Uma lokhu kuqhubeka isikhathi eside, kuzoshisa ama-motor windings.
Ungaqali ngaphansi kwezimo zokulahlekelwa kwesigaba noma i-voltage engavamile. Ngaphambi kokuqala, kuyadingeka ukuhlola i-voltage yezigaba ezintathu nge-multimeter ukuze uqinisekise ukuthi ifana ne-voltage elinganisiwe yemoto, futhi ukungalingani kwezigaba ezintathu akufanele kudlule u-2%.
Isiqondiso sokuzungezisa se-impeller ye-fan kufanele sihambisane nesiqondiso somcibisholo wezindlu zabalandeli.
Isikhawu phakathi kokuqala okubili okulandelanayo kwefeni efanayo akumele sifinyezwe. Kubalandeli abanamandla angu-≤15kW, isikhawu akufanele sibe ngaphansi kwamaminithi angu-10; kulabo abanamandla angu->15kW, isikhawu kufanele singabi ngaphansi kwemizuzu eyi-15. Lokhu okokuvikela ukuguga kwe-insulation okubangelwa ukushisa okusele kuma-motor windings ukuthi kungachithi. Ama-bearings we-fan motor awakhathaleli.
Kunqatshelwe ngokuphelele ukuqala imishini ngaphandle kokwenza ukuhlolwa komshini ngaphambi kokuqala. Ungaluqali idivayisi kuze kube yilapho i-impeller isiphendulwe ngesandla ukuze kuqinisekiswe ukuguquguquka kwayo, ukuvimbela ukuthwala ukutubeka noma ukulimala kwe-impeller ngenxa ye-jamming noma ukuntuleka kwamafutha.
Ungaphoqi ukuqala ngaphansi kwezimo ezimbi. Esimeni sezulu sokuduma kwezulu, lapho abalandeli bangaphandle behlangabezana nemimoya enamandla (isivinini somoya> 10m/s), noma uma ukugcwala kothuli/amagesi abolayo kudlula izinga, ukuqalisa kufanele kumiswe ukuze kuvinjelwe ukungasebenzi kwemishini noma izingozi zokuphepha.
III. Izidingo Ezibalulekile Zokuqapha Ukusebenza
Imizuzu yokuqala eyi-15 ngemuva kokuqala iyinkathi yokuqapha ebalulekile. Ngalesi sikhathi, umthamo wemoto, izinga lokushisa elithwalayo kanye namanani wokudlidliza kufanele kurekhodwe njalo ngemizuzu emi-5. Eyamanje kufanele izinze phakathi kuka-±10% yenani elilinganiselwe, izinga lokushisa elithwalayo akufanele lidlule u-75℃, futhi inani lokudlidliza akufanele lidlule u-4.5mm/s (amanani athile angaphansi kwebhukwana lemishini).
Ukuqapha ngesikhathi sangempela umsindo wokusebenza kwemishini kuyadingeka. Umsindo ojwayelekile kufanele ube “u-hum” onganyakazi. Uma imisindo ebukhali engavamile, imisindo yokushayisana ngezikhathi ezithile noma imisindo yokungqubuzana kwenzeka, umshini kufanele umiswe ngokushesha ukuze uhlolwe ukuze kukhishwe izinkinga ezifana nokuhlikihla i-impeller ngokumelene ne-casing noma imisindo engavamile evela kuma-motor bearings.
Hlala ubhekisisa izinsimbi nezibani zenkomba kukhabhinethi yokulawula. Uma amaphutha anjengokuthi “overcurrent”, “overtemperature”, noma “fase loss” kubikwa, misa umshini ngokushesha. Kuphela ngemva kokuba amaphutha esusiwe futhi ama-alamu asethwe kabusha lapho umshini ungaqalwa kabusha. Kwenqatshelwe ngokuphelele ukusebenza namaphutha.
IV. Amanothi Ngokulungiswa Kwezisetshenziswa Nokuhlobana Kwazo
Ngaphambi kokuqala nsuku zonke, inetha elivikelayo endaweni yokungena komoya yesiphephetha-moya kanye nemfucumfucu ezungezile kufanele kusulwe ukuze kuqinisekiswe ukungena kahle komoya kanye nokunqamuka kokushisa. Lokhu kuvimbela udoti ukuthi ungamuncwa kufeni futhi kulimaze i-impeller, noma kubangele izinga lokushisa lemoto lenyuke ngenxa yokungashisi kahle ukushisa.
Uthuli lwe-impeller kufanele luhlanzwe kanye ngenyanga, ikakhulukazi kubalandeli abasetshenziswa ezindaweni ezinothuli. Ukuqoqwa kothuli kungabangela ukuthi i-impeller ingalingani futhi ikhulise umthwalo wokuqala. Lapho uhlanza, amandla kufanele anqunywe futhi i-impeller kufanele ilungiswe ukuvimbela ukujikeleza ngengozi.
Zonke izimo zokuhlola, ukuqalisa kanye nokuphatha amaphutha kufanele zirekhodwe ngokuningiliziwe, futhi “Ifomu Lokusebenza Kwabalandeli Be-Axial Nokugcinwa Kwerekhodi” kufanele ligcwaliswe. Okuqukethwe okurekhodiwe kufanele kufake phakathi isikhathi sokuqalisa, idatha yepharamitha, izenzakalo zephutha nemiphumela yokusingatha, futhi kufakwe kungobo yomlando okungenani unyaka owodwa. Kubalandeli be-BT30 abangaqhumi, kufanele kuqashelwe okwengeziwe: ibhokisi lokuhlangana kufanele livalwe kahle, amaswishi kufanele angaqhumi noma afakwe ezindaweni ezingaqhumi ukuze kuvinjelwe izinhlansi zikagesi ukuba zingabangeli ingozi.
