Blower classification uye kupatsanura chigadzirwa kuenzanisa
Iyo blower inoreva fan iyo yakazara yekubuda kumanikidza iri 30-200kPa pasi pemamiriro ekugadzira.Zvinoenderana nezvimiro zvakasiyana uye misimboti yekushanda, ma blowers anowanzo kupatsanurwa kuita zvakanaka kusimuka uye turbine.Positive displacement blowers compress uye kutakura gasi nekushandura huwandu hwegasi, inowanzozivikanwa seRoots blowers uye screw blowers;turbine blowers compress uye kutakura gasi kuburikidza nemashizha anotenderera, kunyanya kusanganisira centrifugal uye axial kuyerera.Parizvino, inonyanya kushandiswa ndeye Roots blower uye centrifugal blower.
A centrifugal blower anowanzo kuumbwa ne impeller, volute, mota, frequency converter, bearing, control system, uye bhokisi, pakati peiyo impeller, mota, uye kutakura ndizvo zvinhu zvikuru zvepakati.Kuenzaniswa neRoots blower, iyo centrifugal blower ine yakafara sarudzo renji maererano nekuwedzera kumanikidza uye kuyerera paramita, uye ine hunhu hwepamusoro-soro, ruzha rwakadzika, uye kushanda kwakagadzikana.Indasitiri yemakemikari uye minda mitsva yekudzivirira kwezvakatipoteredza senge kurapwa kwetsvina, tsvina kupisa kudzoreredza, desulfurization uye denitrification.Centrifugal blowers anonyanya kusanganisira echinyakare-chikamu chimwe-centrifugal blowers, akawanda-nhanho centrifugal blowers, air suspension centrifugal blowers uye magineti suspension centrifugal blowers anomiririra tekinoroji yepamusoro muindasitiri.
Traditional single-stage uye multi-stage centrifugal blowers ane zvimiro zvakaoma, yakakwirira kutadza mitengo, inorema kuchengetedza basa uye yakanyanya kudhura mari yekugadzirisa, uye inogara ichidonha yemafuta ekuzora uye girizi, zvichikonzera kusvibiswa kwemhepo nemhepo.
Iyo magineti levitation centrifugal blower inotora iyo magineti levitation inobereka tekinoroji, iyo inochengetedza yakaoma giya bhokisi uye ine mafuta inotakura inodiwa kune yechinyakare blower, uye haigone yekuzora mafuta uye isina mekiniki kugadzirisa, iyo zvinobudirira inoderedza mushandisi gare gare mutengo wekugadzirisa.Iyo magnetic levitation inotakura control system yakanyanya kuoma., Chigadzirwa chacho chine hunyanzvi hwepamusoro uye hupenyu hurefu hwebasa.
Air suspension bearings mabearings anoshandisa mweya semafuta.Mhepo semafuta ane hunhu hwekudzika-viscosity, uye makemikari ayo akadzikama kupfuura zvinwiwa munzvimbo yakakura yekupisa.Midziyo inodiwa kudzvanya mukati uye kubvisa iyo yemvura lubricant, iyo inotakura chimiro inorerutswa, mutengo wekutakura unoderedzwa, uye ine zvakanakira kudzikisa vibration, kuderedza ruzha uye kuchengetedza yakamanikidzwa yepakati isina kusvibiswa.Yakave ichishandiswa zvakanyanya muindasitiri ye blower mumakore achangopfuura.Mhepo yekumisa centrifugal blower inoshandisa mabearings emhepo, yakananga coupling tekinoroji, yakakwirira-inoshanda impellers, high-speed motors, hapana kuwedzera kukweshera, kunenge kusina vibration, hapana yakakosha yekuisa hwaro inodiwa, uye yekumisikidza iri nyore uye inochinjika.
Blower Indasitiri Policy
Mabhowa ndiwo muchina-chinangwa, uye kusimudzira kweindasitiri kunofurirwa uye nekutsigirwa nemitemo yenyika yekugadzira michina.Panguva imwecheteyo, pasi pekusimudzira kwakasimba kwenyika kugadzirwa kwegirinhi, kuchengetedza simba uye kuderedzwa kwekubuda, zvigadzirwa zvekufuridza zvine hunyoro zvichave zvinotarisisa budiriro yeramangwana.Aya anotevera ndiwo ezvino maindasitiri makuru marongero:
Blower Industry Development Overview uye Trends
(1) Kuvandudzwa kwekutarisa kweindasitiri ye blower
kugadzirwa kwenyika yangu yekufuridza kwakatanga kuma1950s.Panguva ino, yainyanya kutevedzera zviri nyore zvezvigadzirwa zvekunze;muma1980s, vagadziri vakuru vekuvhuvhuta vemunyika yangu vakatanga kushandisa dhizaini yakamisikidzwa, yakarongeka, uye yakajairika, iyo yakavandudza zvakanyanya dhizaini yese nedanho rekugadzira.Yakagadzirwa centrifugal blower chigadzirwa chakakodzera zvinodiwa zvenguva.
Mumakore ekuma1990, vagadziri vakuru vekufuridza mudzimba vakaramba vachiunza tekinoroji yekugadzira yekunze pahwaro hwekubatana nemakambani ekunze.Kuburikidza nekugayiwa, kunyura uye kugadzirwa kwekuyedza, iyo R&D uye nhanho yekugadzira yeRoots blowers munyika yangu yakagadziridzwa zvakanyanya, uye centrifugal blower yakashongedzerwa zvakare.Kugadzira uye kugadzira kugona;iyo yakazara tekinoroji nhanho yeindasitiri yekuvhuvhuta iri kukurumidza kuvandudzwa, vanofuridza mudzimba vanogona kuzadzisa zvinodiwa zvekugadzirwa kwemaindasitiri emunyika yangu, uye zvishoma nezvishoma kutsiva kunze kwenyika.
Mushure megore ra2000, kubuda kwese kweindasitiri yekufefetera yenyika yangu kwakaratidza kukwira kumusoro, uye zvigadzirwa zvakaita seRoots blowers zvakatanga kutumirwa kune nyika zhinji nematunhu.Muna 2018, kubuda kweindasitiri yekufefetera yenyika yangu kwaisvika zviuru makumi mashanu nesere, kuwedzera kwegore negore kwe11.9%.Pakati pavo, chikamu chemusika cheRoot blowers chakaverengera 93%, uye chikamu chemusika chemacentrifugal blowers chakaverengera 7%.
Zvichienzaniswa nemakambani makuru ekunze, zvigadzirwa zvekufuridzira nyika yangu zvakatanga kunonoka.Nekukurumidza kukura kwehupfumi hwepamba, kudiwa kweindasitiri yekufuridza kuri kuwedzera.Zvinoenderana nenhamba kubva kuCompressor.com, saizi yemusika wekuvhuvhuta mu2019 ingangoita mabhiriyoni maviri nemazana manomwe emadhora.Mune ramangwana, nekukurumidza kusimukira kwenzvimbo dzepasi dzekushandisa dzakadai semagetsi emagetsi uye kuchenesa tsvina, kudiwa kwevanofuridza kuchawedzera.Zvinotarisirwa kuti musika we blower uchengetedze mwero wekukura we5% -7% mumakore matatu anotevera.
(2) Development Trend yeBlower Indasitiri
① Kubudirira
Mumakore achangopfuura, nemaitiro ekusimudzira ekugadzirwa kwepamusoro-soro, kungwara, uye kusvibira mudzimba, mamwe makambani anofuridza ane chinangwa chekurwadziwa kwekuchengetedza simba uye kuderedzwa kwekushandisa izvo zvinotadzisa kusimukira kweindasitiri.Makambani makuru anofuridza akaenderera mberi achiwana mhedzisiro mukuongorora uye hunyanzvi hwekuchengetedza simba uye kuchengetedza kwezvakatipoteredza matekinoroji emaindasitiri.Nekudaro, mazhinji madiki uye epakati-saizi makambani ekuvhuvhuta achiri kuramba ari mumunda weakaderera-akawedzera zvigadzirwa, izvo zvave imwe yemarwadzo mukusimudzira indasitiri yekufuridza.Kuvandudza mashandiro uye kuderedza mashandisirwo emagetsi ndiwo mafambisirwo asingadzivisiki ebudiriro evanofuridza.
② High-speed miniaturization
Kuwedzera kumhanya kutenderera kunogona kusimudzira zvinobudirira miniaturization yeinofuridza, uye kuwana mhedzisiro yekudzikisa huwandu uye huremu uchivandudza mashandiro.Nekudaro, kuwedzera iyo impeller kumhanya kune yakakwira zvinodiwa kune iyo impeller zvinhu, yekuisa chisimbiso system, inotakura hurongwa uye kugadzikana kwe rotor yekuvhuvhuta, iro idambudziko rinoda kudzidzwa nekugadziriswa mukuvandudzwa kweinofuridza.
③Ruzha rushoma
Ruzha rwekuvhuvhuta zvakanyanya ruzha rweaerodynamic, uye dambudziko reruzha remhepo huru inovhuvhuta.Kumhanya kwayo kwakadzikira, ruzha rweruzha rwakaderera, uye wavelength yakareba, saka hazvisi nyore kuvharira uye kubvisa.Parizvino, tsvakiridzo yekudzikisa ruzha uye kudzikisa ruzha rwevanofuridza iri kuramba ichidzika, senge dhizaini yeakasiyana tuyere maumbirwo ecasing, kushandiswa kwekudzokera shure kudzikisa ruzha, resonance ruzha kuderedza, nezvimwe.
④ Akangwara
Nekuenderera mberi kwekuwedzera kwehukuru hweakasiyana siyana maindasitiri emidziyo, izvo zvinodikanwa zvekugadzira maitiro ekugadzirisa zvakagadzira kubva kune imwechete yekushanda mamiriro parameter control kusvika kune yakawanda yekushanda mamiriro parameter control kuitira kuti isangane nezvinodiwa zvekugadzira maitiro.Akasiyana siyana ekushandisa maparamendi eiyo blower anogona kunyatso kudzorwa nekushandisa PLC, single-chip microcomputer kana PC, uye maparamendi anoshanda eiyo blower anogona kugadziridzwa otomatiki munguva chaiyo zvichienderana neshanduko yemamiriro ekushanda maparamita kuti asangane nezvinodiwa zve maitiro, uye kudzvanywa, tembiricha, vibration, etc. Parameter yekutarisa kuchengetedza kushanda kwakachengeteka kwefani.
