Kugawa kwa Blower ndi kuyerekeza kwa zinthu zogawika
Chopopera mpweya chimatanthauza fani yomwe mphamvu yake yonse yotulutsa mpweya ndi 30-200kPa malinga ndi kapangidwe kake. Malinga ndi kapangidwe ndi mfundo zosiyanasiyana zogwirira ntchito, zopopera mpweya nthawi zambiri zimagawidwa m'magulu awiri: positive displacement displacement ndi turbine. Positive displacement blowers zimapopera ndi kutumiza mpweya mwa kusintha kuchuluka kwa mpweya, zomwe zimadziwika kuti Roots blowers ndi screw blowers; turbine blowers zimapopera ndi kutumiza mpweya kudzera m'mabala ozungulira, makamaka kuphatikiza centrifugal ndi axial flow. Pakadali pano, zomwe zimagwiritsidwa ntchito kwambiri ndi Roots blower ndi centrifugal blower.
Choyatsira mpweya cha centrifugal nthawi zambiri chimakhala ndi impeller, volute, mota, chosinthira ma frequency, bearing, control system, ndi bokosi, lomwe pakati pake impeller, mota, ndi bearing ndi zigawo zazikulu. Poyerekeza ndi choyatsira mpweya cha Roots, choyatsira mpweya cha centrifugal chili ndi mitundu yosiyanasiyana yosankha pankhani ya kukakamiza ndi kuyenda kwa mpweya, ndipo chili ndi mawonekedwe a kugwira ntchito bwino, phokoso lochepa, komanso kugwira ntchito kokhazikika. Makampani opanga mankhwala ndi malo atsopano oteteza chilengedwe monga kukonza zimbudzi, kubwezeretsa kutentha kwa zinyalala, kuchotsa sulfurization ndi denitrification. Zoyatsira mpweya za centrifugal zimaphatikizapo zoyatsira mpweya zachikhalidwe za centrifugal za single-stage, zoyatsira mpweya za multi-stage, zoyatsira mpweya za centrifugal ndi zoyatsira mpweya za centrifugal za magnetic suspension zomwe zimayimira ukadaulo wapamwamba mumakampani.
Ma centrifugal blowers achikhalidwe okhala ndi gawo limodzi komanso ambiri ali ndi nyumba zovuta, kulephera kwakukulu, ntchito yokonza zinthu zambiri komanso ndalama zambiri zokonzera, ndipo nthawi zambiri amataya mafuta ndi mafuta odzola, zomwe zimayambitsa kuipitsidwa kwa chilengedwe komanso mpweya wopanikizika.
Chopopera cha centrifugal cha magnetic levitation chimagwiritsa ntchito ukadaulo wa magnetic levitation bearing, womwe umasunga bokosi la giya lovuta komanso mafuta ofunikira pa blower yachikhalidwe, ndipo sichikwaniritsa mafuta odzola komanso kukonza makina, zomwe zimachepetsa mtengo wokonza wa wogwiritsa ntchito pambuyo pake. Dongosolo lowongolera magnetic levitation bearing ndi lovuta kwambiri. , Chogulitsachi chili ndi zinthu zambiri zaukadaulo komanso nthawi yayitali yogwira ntchito.
Ma bearing oimika mpweya ndi ma bearing omwe amagwiritsa ntchito mpweya ngati mafuta. Mpweya ngati mafuta uli ndi mawonekedwe a kukhuthala kochepa, ndipo mankhwala ake ndi okhazikika kuposa zakumwa zomwe zimakhala ndi kutentha kwakukulu. Zipangizo zofunika kuti zilowe ndikutulutsa mafuta amadzimadzi, kapangidwe ka bearing kamakhala kosavuta, mtengo wa bearing umachepetsedwa, ndipo uli ndi ubwino wochepetsa kugwedezeka, kuchepetsa phokoso ndikusunga malo opanikizika kuti asaipitsidwe. Wagwiritsidwa ntchito kwambiri mumakampani opanga ma blower m'zaka zaposachedwa. Chopopera mpweya chopopera mpweya chimagwiritsa ntchito ma bearing a mpweya, ukadaulo wolumikizira mwachindunji, ma impeller ogwira ntchito bwino, ma mota othamanga kwambiri, palibe kukangana kwina, pafupifupi palibe kugwedezeka, palibe maziko apadera okhazikitsa omwe amafunikira, ndipo kapangidwe kake ndi kosavuta komanso kosinthasintha.
Ndondomeko ya Makampani Opanga Blower
Makina opopera ndi makina ogwiritsidwa ntchito nthawi zonse, ndipo chitukuko cha mafakitale chimakhudzidwa ndi ndondomeko za dziko zopangira zida. Nthawi yomweyo, pansi pa kukwezedwa kwamphamvu kwa dzikolo kwa kupanga zinthu zobiriwira, kusunga mphamvu ndi kuchepetsa utsi, zinthu zopopera zogwira ntchito bwino kwambiri zidzakhala cholinga chachikulu cha chitukuko chamtsogolo. Izi ndi mfundo zazikulu zamakampani zomwe zikuchitika pano:
Chidule cha Kukula kwa Makampani a Blower ndi Zochitika Zake
(1) Chidule cha chitukuko cha makampani opanga ma blower
Kupanga makina opukutira mpweya m'dziko langa kunayamba m'zaka za m'ma 1950. Pa nthawiyi, chinali kungotsanzira zinthu zakunja; m'zaka za m'ma 1980, opanga makina opukutira mpweya akuluakulu m'dziko langa anayamba kugwiritsa ntchito kapangidwe kogwirizana, kotsatizana, komanso kophatikizana, komwe kunasintha kwambiri kapangidwe ndi kapangidwe kake konse. Anapanga makina opukutira mpweya a centrifugal oyenerera zosowa za nthawiyo.
M'zaka za m'ma 1990, opanga makina akuluakulu opukutira mpweya m'dziko muno adapitiliza kuyambitsa ukadaulo wapamwamba wopanga zinthu zakunja potengera mgwirizano ndi makampani akunja. Kudzera mu kugaya, kuyamwa ndi kupanga mayeso, kuchuluka kwa kafukufuku ndi chitukuko ndi kupanga kwa makina opukutira mpweya m'dziko langa kwasintha kwambiri, ndipo makina opukutira mpweya a centrifugal nawonso poyamba adakonzedwa. Mphamvu zopangira ndi kupanga; mulingo wonse waukadaulo wamakampani opukutira mpweya ukukwera mofulumira, makina opukutira mpweya m'dziko muno amatha kukwaniritsa zosowa za mafakitale a dziko langa, ndikubwezeretsa pang'onopang'ono zinthu zomwe zatumizidwa kunja.
Pambuyo pa chaka cha 2000, ntchito yonse yogulitsa makina opukutira mpweya m'dziko langa inayamba kukwera, ndipo zinthu monga makina opukutira mpweya a Roots zinayamba kutumizidwa kumayiko ndi madera ambiri. Mu 2018, ntchito yogulitsa makina opukutira mpweya m'dziko langa inali pafupifupi mayunitsi 58,000, kuwonjezeka kwa chaka ndi chaka kwa 11.9%. Pakati pawo, gawo la msika wa makina opukutira mpweya a Roots linali 93%, ndipo gawo la msika wa makina opukutira mpweya a centrifugal linali 7%.
Poyerekeza ndi makampani akuluakulu akunja, zinthu zopangira makina opopera mpweya m'dziko langa zinayamba mochedwa. Chifukwa cha kukula kwachuma cha m'dziko muno, kufunikira kwa makampani opanga makina opopera mpweya kukuwonjezeka. Malinga ndi ziwerengero kuchokera ku Compressor.com, kukula kwa msika wa makina opopera mpweya m'dziko muno mu 2019 ndi pafupifupi 2.7 biliyoni yuan. M'tsogolomu, chifukwa cha kukula kwachangu kwa malo ogwiritsira ntchito magetsi monga magetsi ndi zimbudzi, kufunikira kwa makina opopera mpweya kudzawonjezeka kwambiri. Akuyembekezeka kuti msika wa makina opopera mpweya udzakhalabe ndi kukula kwa 5%-7% m'zaka zitatu zikubwerazi.
(2) Chitukuko cha Makampani Opanga Ma Blower
① Kuchita bwino
M'zaka zaposachedwapa, chifukwa cha chitukuko cha kupanga zinthu zapamwamba, zanzeru, komanso zobiriwira m'nyumba, makampani ena opanga ma blower akhala akuyang'ana kwambiri pazovuta zosungira mphamvu ndi kuchepetsa kugwiritsa ntchito mphamvu zomwe zimalepheretsa chitukuko cha makampaniwa. Makampani akuluakulu opanga ma blower akhala akupeza zotsatira zabwino pakufufuza ndi kupanga zatsopano zaukadaulo watsopano wosunga mphamvu komanso kuteteza chilengedwe. Komabe, makampani ambiri ang'onoang'ono ndi apakatikati opanga ma blower akadali m'munda wa zinthu zotsika mtengo, zomwe zakhala chimodzi mwazovuta kwambiri pakukula kwa makampani opanga ma blower. Kuwongolera magwiridwe antchito ndi kuchepetsa kugwiritsa ntchito mphamvu ndi njira zosapeŵeka za chitukuko cha ma blower.
② Kuchepetsa liwiro kwambiri
Kuonjezera liwiro lozungulira kungathandize kuti chowombera chichepetse mphamvu, komanso kuchepetsa kuchuluka kwa voliyumu ndi kulemera kwa makinawo pamene chikuwongolera bwino ntchito. Komabe, kuwonjezera liwiro la chipolopolo kuli ndi zofunikira zambiri pa zipangizo za chipolopolo, makina otsekera, makina operekera mphamvu ndi kukhazikika kwa chowombera, lomwe ndi vuto lomwe liyenera kuphunziridwa ndikuthetsedwa popanga chowomberacho.
③Phokoso lochepa
Phokoso la chophulitsira mpweya makamaka limakhala phokoso la aerodynamic, ndipo vuto la phokoso la chophulitsira chachikulu ndi lodziwika bwino. Liwiro lake ndi lochepa, phokoso limakhala lochepa, ndipo kutalika kwa nthawi ndi yayitali, kotero sikophweka kuletsa ndi kuchotsa. Pakadali pano, kafukufuku wokhudza kuchepetsa phokoso ndi kuchepetsa phokoso la zophulitsira mpweya ukukulirakulira, monga kapangidwe ka mitundu yosiyanasiyana ya tuyere ya chivundikirocho, kugwiritsa ntchito kuchepetsa phokoso la backflow, kuchepetsa phokoso la resonance, ndi zina zotero.
④ Wanzeru
Ndi kukula kosalekeza kwa kukula kwa zida zosiyanasiyana zamafakitale apakhomo, zofunikira pakulamulira njira zopangira zakula kuchokera pakuwongolera magawo a ntchito imodzi kupita kukuwongolera magawo a ntchito zambiri kuti zikwaniritse bwino zofunikira za njira yopangira. Magawo osiyanasiyana ogwirira ntchito a chowombera amatha kuwongoleredwa bwino pogwiritsa ntchito PLC, microcomputer imodzi-chip kapena PC, ndipo magawo ogwirira ntchito a chowombera amatha kusinthidwa nthawi yeniyeni malinga ndi kusintha kwa magawo a ntchito kuti akwaniritse zofunikira za ndondomekoyi, komanso kuthamanga, kutentha, kugwedezeka, ndi zina zotero. Kuyang'anira magawo kuti ateteze magwiridwe antchito otetezeka a fan.
