I-centrifugal blower eneenkqubo zeemoto ixazulula enye indawo yeentlungu eziqhubekayo: ukulahlekelwa kwamandla ekudibaneni. Siye sabona izityalo ezininzi kakhulu zilahlekelwa yi-8-12% yokusebenza kakuhle ngenxa nje ye-belt slippage, ukungahambi kakuhle, okanye ukuthwala ukuthwala kwiiseti ze-drive ezingathanga ngqo. Yiyo loo nto izivutheli ze-centrifugal eziqhutywa ngokuthe ngqo-ingakumbi ezo zenzelwe umsebenzi oqhubekayo wemizi-mveliso-ziye zaba ngamahashe athuleyo emva kokuhamba komoya okuzinzileyo, i-OPEX esezantsi, kunye nolawulo olungqongqo lwenkqubo.
Kutheni i-Direct-Drive ibetha ii-Belt okanye iiSeti ezidityanisiweyo
I-Direct-drive ithetha ukuba i-motor shaft idibanisa ngokuthe ngqo kwi-hub ye-impeller-akukho mabhanti, akukho ukudibanisa, akukho shafts ephakathi. Kumsebenzi wehlabathi lokwenyani, oku kuphelisa ii-vectors ezintathu ezisilelayo esizilandela kuzo zonke iisayithi zokungenisa umoya kwimigodi kunye nemigca yokusetyenzwa kweekhemikhali: ukudinwa okubangelwa kukungcangcazela, ukutyibilika kolungelelwaniso emva kokuhamba ngebhayisekile eshushu, kunye nokugcinwa kwexesha lokuphumla ukusuka kuhlengahlengiso loxinzelelo. I-Zibo Hongcheng Fan Co., Ltd. I-4-72-11 No.8C i-stainless steel centrifugal blower kunye ne-30 kW IE3 motor edibeneyo iqhube iiyure ze-14,200 ngaphandle kokuthwala ukutshintshwa-ngelixa iqabane layo eliqhutywe ngebhanti kwi-duct system efanayo lifuna utshintsho olusixhenxe kunye nokutshintshwa kwebhanti ezine ngexesha elifanayo.
Oku akuyothiyori. Ukuqhuba ngokuthe ngqo kunciphisa ilahleko yoomatshini ukuya ngaphantsi kwe-2%. Ibhanti iqhuba umndilili we-5–9% yelahleko. Iibhokisi zegiya? 10–15%. Loo mahluko udibanisa ngokukhawuleza: i-75 kW blower eqhuba i-24/7 kwi-80% yomthwalo igcina ngaphezu kwe-$ 2,100 / ngonyaka kumbane kuphela xa utshintshela ukusuka kwibhanti ukuya ngqo kwi-drive-ngaphambi kokuba i-factoring in labour, i-spare parts, kunye nokuvalwa okungacwangciswanga.
Kodwa idrayivu ethe ngqo inikezela ngexabiso kuphela ukuba i-motor kunye ne-impeller zihambelana ne-thermal kunye ne-dynamically. Siye savavanya iiyunithi apho ukungahambelani kokwandiswa kwe-thermal coefficients kubangele i-rotor rub ngaphakathi kweeyure ezingama-300. Ukulungiswa? Izindlu zeemoto ezidibeneyo ezineendlela zokupholisa ekwabelwana ngazo-kunye ne-impellers elinganayo kwi-ISO 1940 G2.5 kwisantya sokusebenza, kungekhona nje ibhalansi ye-static.
Yintoni abathengi abangayijongiyo (kwaye bazisole kamva)
Abanye bacinga ukuba "i-centrifugal blower enenjini" ithetha ukuplagi kunye nokudlala ngokulula. Akunjalo. Imiqobo emithathu efihliweyo inyusa amaqela anamava okuthenga:
- Ukunyuka kokuqina kubaluleke ngaphezu kwetorque elinganisiweyo. Iyunithi efakwe kwi-flange kwiplatifomu yensimbi encinci iya kudlulisela i-resonance kwi-ductwork-ebangela ukukhathala ukuqhekeka kufuphi ne-elbows. Sichaza ubuncinci beplate yesiseko ubukhulu (≥25 mm kwiiyunithi ezingaphezulu kwe-30 kW) kwaye ifuna i-grouting ngokwe-ISO 10816-3 yeklasi yokungcangcazela.
- Ukuhambelana kweVFD akuzenzekelanga. Ayizizo zonke iimotor ezidibeneyo ezibamba i-4: 1 turndown ngaphandle kokunciphisa. Iimotor zethu ezisemgangathweni ze-IE3 ziquka ukugqunywa kweKlasi F, ukupholisa umoya ngenkani, kunye ne-VFD-rated windings-kodwa kuphela xa ichaziwe kwinqanaba lokuodola. Iiyunithi zithunyelwa ngaphandle kwaloo nkcazo zihlala zitshisa ngaphantsi kwe-35 Hz.
- Ukumelana nomhlwa kuqala kwizindlu zeemoto. I-impellers yensimbi engenasici ayithethi nto ukuba isakhelo semoto sipeyintwe ngentsimbi ethambileyo. Kwiiplatifomu ezingaselunxwemeni okanye imigca yokuphatha iklorine, sisebenzisa i-AISI 316L epheleleyo yeemoto ezivaliweyo-kungekhona nje ivili lomqhubi.
Abathengi abatsiba ezi zitshekisho bajongana neendleko ze-retrofit 3 × ixabiso leyunithi yokuqala. Omnye umxhasi olungisa ukutya uye wathatha indawo yesixhobo sokuvuthela esiphuma kwishelufu emva kweenyanga ezintandathu ngenxa yokuba uxinaniso lwenzekile ngaphakathi kwendlu yemoto engangeni moya. Isisombululo sasingelophawu olutsha-beluchaza ukutywinwa kwe-IP66, i-drain vents, kunye ne-silica gel cartridges yangaphakathi.
Ukuthelekisa iYunithi kwiNkqubo Yakho-Hayi nje iKhathalogi
"I-centrifugal blower enemoto" ayikhethwa ngamandla ehashe kuphela. Ilinganiswe ngokwenkqubo yegophe yokudibana. Sicela wonke umthengi ngelungiselelo lokwenyani lombhobho-hayi nje iithagethi zoxinzelelo olumileyo. Ngoba? Kuba inkqubo ye-1,200 ye-Pa ene-elbows ye-90 ° kunye ne-dampers ezintathu aziphathi nto njenge-1,200 Pa i-duct echanekileyo. Ilahleko yokwenyani evela kwisiphithiphithi inokongeza i-30-50% ngaphaya kokubala kweencwadi zokufunda.
Yiyo loo nto iinjineli zethu zijonga isicatshulwa ngasinye ngokuchasene namanqaku amathathu edatha: iprofayile yesantya sokungena esilinganisweni, uburhabaxa bemathiriyeli (ε), kunye neyona meko imbi kakhulu yobushushu/ukujinga kokufuma. Ngokomzekelo, iyunithi ye-55 kW eqhuba ngokuthe ngqo kwi-biomass dryer e-Shandong ibaleka kwi-1,850 rpm kwindawo yokuyila-kodwa yehla ukuya kwi-1,320 rpm ngexesha le-monsoon ngenxa yobuninzi bomoya. Ngaphandle kwalo mda, ukuhamba komoya kuya kuwela nge-12% ngaphantsi kwe-spec.
Sigcina ngaphezulu kwe-600 yolungelelwaniso-kubandakanya abalandeli be-axial flow mining, iimodeli ze-polyester ezinganyangekiyo kwi-corrosion, kunye ne-high-temp centrifugal ventilators ezibekwe kwi-400 ° C. Kodwa kwizicelo zokuqhuba ngokuthe ngqo, uchungechunge lwethu oluceliwe kakhulu yilayini ye-4-72-11 kunye ne-G4-73: zombini zibonelela nge-impellers ezigobileyo zangasemva (ukuphumelela okuphezulu kwe-84-87%), izindlu ze-aluminium eziphosiweyo, kunye nokukhethwa kweemoto ukusuka kwi-1.5 kW ukuya kwi-200 kW-ngokuthotyelwa ngokupheleleyo kwi-GB / T 1230 kunye novavanyo lwe-ISOCA 1230, i-ISOCA 1236, i-ISO 1230, kunye novavanyo lwe-ISO 1236.
Umgca osezantsi: Ukusebenza kakuhle onokuthi ulinganise, hayi nje ukufaka ibango
I-centrifugal blower enezisombululo zemoto ihambisa i-ROI enokulinganiswa-hayi amabango okuthengisa. Banciphisa ukusetyenziswa kwamandla. Bacutha iifestile zokulungisa. Bandisa ubomi benkonzo ngokususa amakhonkco abuthathaka oomatshini. Kodwa kuphela xa yenziwe njengendibano enye ejikelezayo-engadityaniswanga emva kwenyani.
I-Zibo Hongcheng Fan Co., Ltd. yakha ezi yunithi kwindawo apho ukusilela kungenakuzikhethela: imigodi engaphantsi komhlaba enobungozi berhasi eqhumayo, imigca ye-electroplating ephethe inkungu ye-hydrochloric acid, kunye neesilo zengqolowa ezifuna isiqinisekiso sobungqina bokudubula. Ikhathalogu yabo igubungela uthotho lwe-50-kodwa i-centrifugal blower eqhuba ngokuthe ngqo ihlala ilolona khetho luphezulu kubasebenzisi abalandelela i-kWh, hayi i-kW kuphela.
Jonga ngaphaya kweleyibhile. Jonga ujongano lwe-thermal phakathi kwemoto kunye ne-impeller. Qinisekisa ukuba imilinganiselo yokunyuka ihambelana nesiseko sakho-hayi nje incwadana. Banga idatha yokungcangcazela igcwele ngokupheleleyo, hayi ukungenzi nto. Emva koko uya kufumana ukuba zeziphi izithembiso zokuqhuba ngokuthe ngqo: ukuthula, ukuzinza, kunye nokugcinwa kwezinto ezibonisa kwimitha.
