Uhlobo lwesithuba sefeni yesityalo sesamente sokuchitha ubushushu
I. Imigaqo yokuSebenza ngoKhuseleko olungundoqo
-Phambi kokusebenza, kubalulekile ukuqinisekisa ukuba ukhuseleko lomntu lukhona. Nxiba iiglavu ezigqunyiweyo kunye nezihlangu zokusebenza ezichasene nokutyibilika. Iinwele ezinde mazibotshwe. Impahla ekhululekileyo okanye ubucwebe inqatshelwe ngokungqongqo ukuthintela ukuphonswa kwiindawo ezijikelezayo.
Ngaphambi kokuqala, indawo yokusebenza kufuneka ihlanjululwe, kwaye isibonakaliso sesilumkiso sifundeka "Izixhobo zokuqalisa, akukho kungena" kufuneka zisekwe ukuze kuqinisekiswe ukuba abasebenzi abangabalulekanga baphume kwindawo ekhuselekileyo, ukukhusela ukulimala okubangelwa yimpembelelo yokuhamba komoya okanye i-detachment yecandelo.
Yonke imisebenzi kufuneka yenziwe ngabasebenzi abaqinisekisiweyo abafumene uqeqesho olukhethekileyo. Abangengabo abachwephesha banqatshelwe ngokungqongqo ukuba babambe iiswitshi zekhabhathi yolawulo, iintambo zeemoto, kunye neenxalenye ezijikelezayo zefeni. Ngexesha lokugcinwa, inkqubo ye-"power off - tag - lock" kufuneka ilandelwe ngokungqongqo.
Kwimeko nayiphi na imeko engxamisekileyo ngexesha lenkqubo yokuqalisa (njengabasebenzi abangagunyaziswanga abangena okanye izandi ezivakalayo ezingaqhelekanga ezivela kwisixhobo), ngokukhawuleza cofa iqhosha elithi "Emergency Stop" kwikhabhinethi yokulawula ukunqumla ukunikezelwa kombane, uze uqhubeke nokuphatha okulandelayo. Akuvumelekanga ngokungqongqo ukuphazamisa ngokuthe ngqo isixhobo ngelixa sisebenza.
II. ImiGaqo eKhethekileyo yokuQalisa imiSebenzi
I-axial flow fan yenzelwe into ethi "no-load start". Umbhobho womoya ovaliweyo uya kubangela ukwanda ngokukhawuleza kokumelana nokuhamba komoya, okukhokelela ekugqithiseni kwemoto kunye nokukhubeka. Ukuba oku kuyaqhubeka ixesha elide, kuya kutshisa ii-motor windings.
Musa ukuqala phantsi kweemeko zokulahleka kwesigaba okanye umbane ongaqhelekanga. Ngaphambi kokuqala, kuyimfuneko ukujonga i-voltage yesigaba sesithathu kunye ne-multimeter ukuqinisekisa ukuba ihambelana ne-voltage elinganisiweyo yemoto, kwaye ukungalingani kwesigaba sesithathu akufanele kudlule i-2%.
Umkhombandlela wokujikeleza we-impeller yefeni kufuneka uhambelane nesalathiso sotolo kwizindlu zabalandeli.
Ikhefu eliphakathi kokuqalisa kabini ngokulandelelana kwefeni enye akufunekanga licuthwe. Kubalandeli abanamandla ≤15kW, ikhefu kufuneka libe ngaphantsi kwemizuzu eyi-10; kwabo banamandla angama->15kW, ikhefu kufuneka lingabi ngaphantsi kwemizuzu eyi-15. Oku kukuthintela ukuguga kokugquma okubangelwa bubushushu obushiyekileyo kwi-motor windings ukuba bungachithi. Iibheringi zenjini yefeni azigcinwanga.
Akuvumelekanga ngokungqongqo ukuqalisa izixhobo ngaphandle kokwenza uhlolo lomatshini ngaphambi kokuqalisa. Musa ukuqalisa isixhobo de i-impeller iguqulwe ngesandla ukuze iqinisekise ukuguquguquka kwayo, ukuthintela ukuthwala ukutshiswa okanye ukonakala kwe-impeller ngenxa ye-jamming okanye ukungabikho kweoli.
Musa ukunyanzelisa ukuqala phantsi kweemeko ezimbi. Kwimozulu yezulu, xa abalandeli bangaphandle bedibana nemimoya enamandla (isantya somoya> 10m / s), okanye xa ukuxinwa kothuli / iigesi ezitshabalalisayo zidlula umgangatho, ukuqala kufuneka kumiswe ukuthintela ukusilela kwezixhobo okanye iingozi zokhuseleko.
III. IiMfuno eziPhambili zokuBeka iliso kuMsebenzi
Imizuzu yokuqala eyi-15 emva kokuqalisa lixesha elibalulekileyo lokubeka iliso. Ngeli xesha, i-motor current, i-motor current, i-bearing heat and vibration values kufuneka irekhodwe yonke imizuzu emi-5. Umjelo okhoyo kufuneka uzinzile ngaphakathi kwe-± 10% yexabiso elilinganisiweyo, izinga lokushisa akufanele lidlule i-75 ℃, kwaye ixabiso le-vibration akufanele lidlule i-4.5mm / s (amaxabiso athile axhomekeke kwincwadana yezixhobo).
Ukujongwa kwexesha langempela kwisandi sokusebenza kwesixhobo kuyimfuneko. Isandi esiqhelekileyo kufuneka sibe "hum" ngokuzinzileyo. Ukuba izandi ezibukhali ezingaqhelekanga, izandi zempembelelo zethutyana okanye izandi zokukhuhlana ziyenzeka, umatshini kufuneka umiswe ngoko nangoko ukuze uhlolwe ukuze kuthintelwe iingxaki ezinjengokuhlikihla kwe-impeller kwi-casing okanye izandi ezingaqhelekanga ezivela kwiibheringi zeemoto.
Gcina ujongo olusondeleyo kwizixhobo kunye nezibane zesalathisi kwikhabhinethi yokulawula. Ukuba iimpazamo ezifana ne "overcurrent", "overtemperature", okanye "ilahleko yesigaba" zixelwe, misa umatshini ngokukhawuleza. Kuphela emva kokuba iziphene zipheliswe kwaye i-alamu iphinda isetyenziselwe umatshini unokuqaliswa kwakhona. Akuvumelekanga ngokungqongqo ukusebenza ngeempazamo.
IV. Amanqaku ngoLondolozo lweZixhobo kunye noNxibelelwano lwaso
Ngaphambi kokuqala yonke imihla, umnatha okhuselayo kwi-air inlet ye-fan kunye ne-debris ejikelezayo kufuneka icocwe ukuze kuqinisekiswe ukungena komoya okulungileyo kunye nokutshatyalaliswa kobushushu. Oku kuthintela i-debris ekubeni ifunxe kwi-fan kwaye yonakalise i-impeller, okanye ibangele ubushushu bemoto bunyuke ngenxa yokutshatyalaliswa kobushushu obungalunganga.
Uthuli lwe-impeller kufuneka lucocwe kanye ngenyanga, ngakumbi kubalandeli abasetyenziswa kwiindawo ezinothuli. Ukuqokelelwa kothuli kunokubangela ukuba i-impeller ingalingani kwaye inyuse umthwalo wokuqala. Xa ucoca, umbane kufuneka unqunyulwe kwaye i-impeller kufuneka ilungiswe ukukhusela ukujikeleza ngengozi.
Zonke iimeko zokuhlola, ukuqalisa kunye nokusingatha iimpazamo kufuneka zibhalwe ngokweenkcukacha, kwaye "iFom ye-Axial Fan Operation and Maintenance Record Form" kufuneka izaliswe. Umxholo orekhodiweyo kufuneka ubandakanye ixesha lokuqalisa, idatha yeparameter, i-fault phenomena kunye neziphumo zokuphatha, kwaye zigcinwe ubuncinane unyaka omnye. Kwiifeni ze-BT30 ezingaqhushumbayo, kufuneka kuqwalaselwe ingqwalasela eyongezelelweyo: ibhokisi yesiphambuka kufuneka itywinwe ngokufanelekileyo, iiswitshi kufuneka zikhuseleke uqhushumbo okanye zifakwe kwiindawo ezingaqhushumbayo ukukhusela iintlantsi zombane ukuba zingabangeli ingozi.
