Gulu la blower ndi kufananiza kwa magawo ang'onoang'ono
Chowombera chimatanthawuza za fan yomwe mphamvu yake yonse yotuluka ndi 30-200kPa pansi pamikhalidwe yopangidwira.Malinga ndi mapangidwe osiyanasiyana komanso mfundo zogwirira ntchito, zowulira nthawi zambiri zimagawika m'malo abwino komanso ma turbine.Zowuzira zabwino zotulutsa mpweya zimapanikiza ndi kunyamula gasi posintha kuchuluka kwa gasi, zomwe zimadziwika kuti Roots blowers ndi screw blowers;turbine blowers compress ndi kunyamula gasi kudzera m'miyala yozungulira, makamaka kuphatikiza centrifugal ndi axial flow.Pakalipano, omwe amagwiritsidwa ntchito kwambiri ndi Roots blower ndi centrifugal blower.
Chowombera cha centrifugal nthawi zambiri chimapangidwa ndi chowongolera, volute, mota, chosinthira pafupipafupi, chonyamula, makina owongolera, ndi bokosi, pomwe chowongolera, mota, ndi zonyamula ndizo zikuluzikulu.Poyerekeza ndi Roots blower, centrifugal blower ili ndi mitundu ingapo yosankha malinga ndi kuthamanga kwamphamvu ndi magawo oyenda, ndipo imakhala ndi mawonekedwe amphamvu kwambiri, phokoso lochepa, komanso magwiridwe antchito okhazikika.Makampani opanga mankhwala ndi malo atsopano otetezera zachilengedwe monga kuchiza zimbudzi, kubwezeretsa kutentha kwa zinyalala, desulfurization ndi denitrification.Ma blower a Centrifugal makamaka amaphatikiza zowulutsira zachikhalidwe zagawo limodzi, zowombera ma centrifugal zamitundu ingapo, zowulutsira mpweya zapakati ndi maginito kuyimitsidwa centrifugal blowers zoyimira ukadaulo wapamwamba pamsika.
Zowulutsira zachikhalidwe zamagawo amodzi ndi ma centrifugal opitilira masitepe ambiri zimakhala ndi zovuta, kulephera kwakukulu, kukhathamiritsa kolemetsa komanso kukwera mtengo kwa kukonza, ndipo sachedwa kutayikira kwamafuta opaka mafuta ndi mafuta, zomwe zimayambitsa kuwonongeka kwa chilengedwe ndi kuponderezedwa kwa mpweya.
Magnetic levitation centrifugal blower imatenga ukadaulo wonyamula maginito, womwe umasunga bokosi la zida zovuta komanso zonyamula mafuta zofunika pakuwomba kwachikhalidwe, ndipo sapeza mafuta opaka mafuta komanso kukonza makina, komwe kumachepetsa mtengo wokonza pambuyo pake.Dongosolo lowongolera maginito levitation ndizovuta kwambiri., Mankhwalawa ali ndi luso lapamwamba komanso moyo wautali wautumiki.
Air kuyimitsidwa mayendedwe ndi mayendedwe kuti ntchito mpweya monga lubricant.Mpweya monga mafuta opangira mafuta amakhala ndi mawonekedwe a kukhuthala kochepa, ndipo mankhwala ake amakhala okhazikika kuposa zakumwa pa kutentha kwakukulu.Zida zomwe zimafunikira kuti zikanikizire ndikuchotsa mafuta amadzimadzi, kapangidwe kake kamakhala kosavuta, mtengo wonyamulira umachepetsedwa, ndipo uli ndi zabwino zochepetsera kugwedezeka, kuchepetsa phokoso ndikusunga sing'anga yoponderezedwa kuti isaipitsidwe.Zakhala zikugwiritsidwa ntchito kwambiri m'makampani owombera m'zaka zaposachedwa.Mpweya woyimitsidwa wa centrifugal blower umagwiritsa ntchito mayendedwe a mpweya, ukadaulo wolumikizana mwachindunji, zowongolera zogwira mtima kwambiri, ma mota othamanga kwambiri, palibe kukangana kowonjezera, pafupifupi kugwedezeka, palibe maziko apadera ofunikira, ndipo masanjidwewo ndi osavuta komanso osinthika.
Blower Industry Policy
Mawotchi ndi makina opangira ntchito, ndipo kukula kwamakampani kumakhudzidwa ndikuthandizidwa ndi mfundo zopangira zida zadziko.Panthawi imodzimodziyo, pansi pa kulimbikitsa kwakukulu kwa dziko la kupanga zobiriwira, kusunga mphamvu ndi kuchepetsa utsi, zopangira zowombera bwino kwambiri zidzakhala cholinga cha chitukuko chamtsogolo.Nawa ndondomeko zazikulu zamakampani:
Blower Industry Development Overview and Trends
(1) Chidule cha chitukuko chamakampani owombera
Kupanga zowuzira zowulira m'dziko langa kunayamba cha m'ma 1950.Panthawi imeneyi, chinali makamaka kutsanzira kosavuta kwa zinthu zakunja;m'zaka za m'ma 1980, opanga mawotchi akuluakulu a dziko langa anayamba kugwiritsa ntchito mapangidwe ogwirizana, osakanikirana, komanso ophatikizana, omwe adasintha kwambiri mapangidwe ndi kupanga.Anapanga chofufutira cha centrifugal choyenera pa zosowa za nthawiyo.
M'zaka za m'ma 1990, opanga ma blower apanyumba akuluakulu adapitiliza kuyambitsa ukadaulo wotsogola wakunja potengera mgwirizano ndi makampani akunja.Kupyolera mu chigayidwe, kuyamwa ndi kupanga kuyesa, R&D ndi kupanga kwa Roots blowers m'dziko langa zakhala zikuyenda bwino, ndipo chowulutsira centrifugal chinalinso ndi zida zoyambira.Kupanga ndi kupanga luso;ukadaulo wamakampani opanga ma blower ukukulirakulira, zowombera m'nyumba zimatha kukwaniritsa zosowa zamafakitale adziko langa, ndikulowa m'malo mwazogulitsa kunja.
Pambuyo pa chaka cha 2000, kuchuluka kwa mafakitale owulutsira dziko langa kunawonetsa kukwera, ndipo zinthu monga Roots blowers zidayamba kutumizidwa kumayiko ndi zigawo zambiri.Mu 2018, zomwe zidatulutsa mdziko langa zidali pafupifupi mayunitsi 58,000, kuwonjezeka kwa chaka ndi 11.9%.Pakati pawo, gawo la msika la Roots blowers lidakhala 93%, ndipo gawo la msika la centrifugal blowers lidakhala 7%.
Poyerekeza ndi makampani otsogola akunja, zotulutsa zowotchera zakudziko langa zidayamba mochedwa.Chifukwa chakukula kwachuma cham'nyumba, kufunikira kwamakampani opanga ma blower kukuchulukirachulukira.Malinga ndi ziwerengero zochokera ku Compressor.com, kukula kwa msika wamafuta akunyumba mu 2019 ndi pafupifupi 2.7 biliyoni.M'tsogolomu, ndikutukuka kwachangu kwa malo ogwiritsira ntchito kunsi kwa mtsinje monga magetsi amagetsi ndi zimbudzi, kufunikira kwa owuzira kuchulukirachulukira.Zikuyembekezeka kuti msika wa blower upitilira kukula kwa 5% -7% mzaka zitatu zikubwerazi.
(2) Chitukuko cha Makampani a Blower
① Kuchita bwino
M'zaka zaposachedwa, ndi chitukuko cha zopanga zapamwamba, zanzeru, komanso zobiriwira zapakhomo, makampani ena opumira amalimbana ndi zowawa zakusunga mphamvu ndi kuchepetsa kugwiritsa ntchito zomwe zimalepheretsa chitukuko chamakampani.Makampani akuluakulu owombera mpweya apeza zotsatira mosalekeza pakufufuza ndi kukonzanso njira zatsopano zamafakitale zopulumutsira mphamvu komanso kuteteza chilengedwe.Komabe, makampani ambiri ang'onoang'ono ndi apakatikati omwe amawotchera amakhalabe m'munda wazinthu zotsika mtengo, zomwe zakhala zopweteka kwambiri pakukula kwamakampani owombera.Kupititsa patsogolo mphamvu ndi kuchepetsa kugwiritsa ntchito mphamvu ndi njira zomwe sizingalephereke za chitukuko cha owombera.
② Kuthamanga kwambiri kwa miniaturization
Kuchulukitsa liwiro lozungulira kumatha kulimbikitsa bwino kuphulika kwa chowombera, ndikupeza zotsatira zochepetsera voliyumu ndi kulemera kwinaku mukuwongolera bwino.Komabe, kuonjezera liwiro la chopondera kuli ndi zofunikira zapamwamba pazida zopangira, kusindikiza, dongosolo lonyamula ndi kukhazikika kwa rotor, lomwe ndi vuto lomwe liyenera kuphunziridwa ndikuthetsedwa pakukula kwa chowombera.
③ Phokoso lochepa
Phokoso la chowuzira makamaka ndi phokoso la aerodynamic, ndipo vuto la phokoso la chowuzira chachikulu ndi lodziwika bwino.Liwiro lake ndi lochepa, mafupipafupi a phokoso ndi otsika, ndipo kutalika kwake kumakhala kwautali, kotero sikophweka kutsekereza ndi kuthetsa.Pakalipano, kafukufuku wochepetsera phokoso ndi kuchepetsa phokoso la owombera akukulirakulirabe, monga mapangidwe amitundu yosiyanasiyana ya tuyere ya casing, kugwiritsa ntchito kuchepetsa phokoso lakumbuyo, kuchepetsa phokoso la resonance, ndi zina zotero.
④ Wanzeru
Ndi kukula kosalekeza kwa kukula kwa zida zosiyanasiyana zapakhomo, zofunikira pakuwongolera njira zopangira zapangidwa kuchokera kuulamuliro umodzi wogwirira ntchito kupita kumagulu ambiri ogwirira ntchito kuti akwaniritse zofunikira pakupangira.Magawo osiyanasiyana ogwiritsira ntchito blower amatha kuwongoleredwa bwino pogwiritsa ntchito PLC, single-chip microcomputer kapena PC, ndipo magawo ogwiritsira ntchito blower amatha kusinthidwa munthawi yeniyeni malinga ndi kusintha kwa magawo ogwirira ntchito kuti akwaniritse zofunikira za ndondomeko, ndi kuthamanga, kutentha, kugwedera, etc. Parameter kuwunika kuteteza otetezeka ntchito zimakupiza.
