I-fan yam yokuphelisa I-K40 ye-mining axial flow fan, ijika lokusebenza ngaphandle kwe-hump, inokubuyisela umva kwaye ibuyisele umva ukuhamba komoya
Isizukulwana esitsha seK40 sabalandeli bomgodi bonga amandla
1. Isishwankathelo
Isizukulwana esitsha se-K kunye ne-DK yabalandeli bokugcina amandla emigodini siyilwe ngokusekwe kubalandeli bokugcina amandla omgodi wokuqala ngokuphuculwa kobugcisa, uphuculo lwesakhiwo, ukuphuculwa kokusebenza, kunye nokwandiswa koluhlu lwemodeli. Olu chungechunge lwabalandeli lubonisa ukusebenza kakuhle okuphezulu, amanqanaba asezantsi engxolo, uluhlu olubanzi lokusebenza, kunye neziphumo ezibalulekileyo zokonga amandla. Ukongezelela, isixhobo sokuhamba ngokuzinzile sifakwe ngaphakathi kombhobho womoya oyintloko, ukuqinisekisa ukuba i-fan inokusebenza ngokuzinzileyo phantsi kwayo nayiphi na imeko yokumelana ngaphandle kwe-hump kwi-curve yokusebenza.
Ukwandisa uluhlu lwentsebenzo yolu luhlu lwabalandeli be-axial flow mgodi kunye nokuhlangabezana neemfuno zemigodi eyahlukeneyo emikhulu, ephakathi, kunye nencinci engeyiyo yamalahle, ukuvumela ukukhethwa kwabalandeli abaphambili, abalandeli abancedisayo, kunye nezikhululo zabalandeli bezigaba ezininzi ezisebenza kwindawo ephezulu, ephakathi, kunye nokuchasana okuphezulu kunye nobukhulu, obuphakathi, kunye nomthamo omncinci womoya wothungelwano lwe-ventilation, olu luhlu lwee-hub ezimbini kunye ne-0 0 yamkela i-040 ye-hub kunye ne-hub ezimbini. iintlobo zezakhiwo ze-single kunye ne-counter-rotating, ngaloo ndlela zihlulwe zibe ziindidi ezine: K40, K45, DK40, kunye ne-DK45. Ngaphezu koko, i-K40 isebenzisa iimotor ezine-4, 6, kunye ne-8-pole kwizantya ezintathu, i-K45 isebenzisa iimotor ezi-4 kunye ne-6-pole kwizantya ezibini, kwaye i-DK40 kunye ne-DK45 zombini zisebenzisa ii-motor ezi-6 kunye ne-8-pole kwizantya ezimbini.
Ngale ndlela, inani lemodeli nganye lidityaniswe nemilinganiselo emibini yeehabhu, iindidi ezimbini zesakhiwo, kunye nezantya ezintathu ngendlela ethile ziphumela kwiinkcukacha ezingama-93 zolu chungechunge lwabalandeli.
Uluhlu lwentsebenzo kunye neeparitha eziphambili zobugcisa zesizukulwana esitsha se-K kunye nochungechunge lwe-DK lwabalandeli bokugcina amandla omgodi ngaphandle kwe-hump luboniswa kwiThebhile 2 kunye neThebhile 3 ngokulandelelanayo. Ubunzima bereferensi obudwelisiweyo kwiitheyibhile bubandakanya i-motor kunye ne-diffuser njengobunzima beyunithi epheleleyo.
Imizobo yesakhiwo kunye nemilinganiselo yangaphandle ye-K40 kunye ne-K45 abalandeli bechungechunge baboniswa kuMfanekiso 6 kunye neThebhile 6, iTheyibhile yesi-7 ngokulandelanayo.
Indlela yokubonisa imodeli yesizukulwana esitsha se-K kunye nochungechunge lwe-DK yabalandeli bokugcina amandla omgodi (umzekelo) lulandelayo: K 40– 4 №.15
Ifeni yam, inombolo yemodeli ye-15, (i-"DJK" uchungechunge luhlobo olujikelezayo lwe-fan yasemgodini) (oko kukuthi, i-diameter yevili elisebenzayo D = 15dr;)
1. Hub ratio d = 0.40, motor pole inani 4, n = 1450 r/min
(“45” ye-d = 0.45) (“6” kwiipali ezi-6, n = 980 r/min; “8” kwiipali ezisi-8, n = 730 r/min)
2. Ukusetyenziswa kwefeni ye-Exhaust yaMayini ye-K40 yomgodi we-axial flow fanK4n0 I-Exhaust yaMayini ye-Fa
Olu luhlu lwabalandeli luyilelwe ngokukodwa iimfuno zokungena komoya kwimigodi eyahlukeneyo engeyiyo yamalahle efana nesinyithi, iintsimbi ezingezizo intsimbi, igolide, ishishini lemichiza, izixhobo zokwakha, kunye neshishini lenyukliya. Zingasetyenziswa njengabalandeli abaphambili okanye abalandeli abancedisayo, kwaye banokufakwa kumphezulu okanye ngaphantsi komhlaba. Zikulungele ukusebenza okudityanisiweyo kwabalandeli abaninzi kwaye zifanelekile kwinqanaba ngalinye leenkqubo ezininzi zokungenisa umoya. Zikwasebenza ekungeneni komoya kunye nokutshintshiselana komoya kwiindibano zocweyo ezinkulu, itonela, kunye neeprojekthi zokhuselo lomoya.
3. Iimpawu ze-Mine exhaust fan K40 ye-mining axial flow fan
(1) Amaphiko ajikiweyo amile okweencakuba amkelwe, anokusebenza okuphezulu kwe-aerodynamic kunye neziphumo ezibalulekileyo zokonga amandla.
(2) Ukusebenza okuhlukeneyo kunye neenkcukacha ezipheleleyo, ezinokuthi zihambelane kakuhle neentlobo ezahlukeneyo zokuchasana kunye neentlobo zomthamo womoya wothungelwano lwe-ventilation, ukugcina ukusebenza kwexesha elide.
(3) Ukuxhotyiswa ngesixhobo sokujikeleza okuzinzileyo, ijika lempawu alinayo i-hump. Akukho mngcipheko wokunyuka, kwaye inokusebenza ngokukhuselekileyo kwaye ngokuzinzileyo phantsi kwazo naziphi na iimeko ezixhathisayo, kwaye ifanelekile kwi-multi-fan edibeneyo yokusebenza.
(4) Isakhiwo soqhagamshelwano oluthe ngqo phakathi kwemoto kunye ne-impeller yamkelwa, ngokuzinza okulungileyo ngokubanzi, ukufakela okulula kunye nokugcinwa, kunye nokuchasana okuphantsi kwendawo yesixhobo. Xa kuthelekiswa nebhanti kunye nokuhanjiswa kwe-shaft ende, inomsebenzi ophezulu wokuhambisa, akukho ziphoso zokuhambisa, akukho mngcipheko wokuphulwa kwe-shaft, kunye nokuhlaliswa kwesiseko esincinci kunye ne-sliding akuchaphazeli ukusebenza okuqhelekileyo.
(5) Ubume obubambekayo kunye nokusebenza kakuhle kobungqina bokufuma. I-fan body yenziwe ngeepleyiti zentsimbi kunye namacandelo entsimbi adityaniswe kunye, kwaye iincakuba zenziwe ngeepleyiti zentsimbi, ezingenanto, ezinencakuba ephezulu kunye namandla ngokubanzi, ukuxhathisa okunamandla kumaza othusayo okuqhuma komhlaba, alungele ukufakwa kumphezulu kunye nangaphantsi komhlaba, alungele ukusetyenziswa ngokukodwa njengefeni yesikhululo kwiinkqubo ezininzi zokungenisa umoya.
(6) Ukubuyisela umva kunye nokuhamba komoya okubuyela umva kunokwenzeka, kunye nesantya sokuhamba komoya esingasemva esikhulu kune-60%, kwaye akukho mfuneko yokwakhiwa kweendlela zomoya ezibuyela umva.
(7) I-angle yokufakela ii-blades iyahlengahlengiswa, ivumela ukulungiswa kweemeko zokusebenza kweefeni ngokweenguqu kwimveliso yomgodi.
(8) Umsebenzi wobunjineli bokwakha umncinci, usindisa utyalo-mali oluninzi.
(9) Ingxolo ephantsi.
4.Ifeni yokukhupha imigodi ye-K40 ye-axial flow fan Diffuser
Xa uchungechunge lwe-K kunye ne-DK yeefeni ezigcina amandla emigodini zisetyenziswa njengabalandeli abaphambili okanye abalandeli besikhululo, kufuneka baxhotyiswe ngee-diffusers ezizinikeleyo. Xa iifeni eziphambili zomphezulu zixhotyiswe ngee-diffusers, inxalenye yoxinzelelo oluguquguqukayo inokuguqulwa ibe luxinzelelo olumileyo, inciphisa ilahleko yoxinzelelo oluguquguqukayo kwindawo yokuphuma ukuze kuphunyezwe iinjongo zokonga amandla. Xa iifeni eziphantsi komhlaba zixhotyiswe nge-diffuser, abanako ukunciphisa kuphela i-coefficient yokumelana nendawo kodwa banciphise ixabiso loxinzelelo oluguquguqukayo kwindawo yokukhupha i-diffuser, ngaloo ndlela behlisa kakhulu ukuxhathisa kwendawo yesixhobo sefeni kunye nokugcina ukusetyenziswa kwamandla omoya.
