Guhitamo uburenganzira Ubwoko bwa FAN ntabwo ari uguhuza numero ya kataloge kurutonde. Nibijyanye no gukemura ikibazo nyacyo-kwimura umwuka mukurwanya, gufata imyotsi yangirika, kurokoka imigezi ya 200 ° C, cyangwa kugumisha ikirombe cyamakara guhumeka mubihe bishobora guturika. Twapimye, twagerageje, kandi dushyira mu bikorwa abafana barenga 1.200 kuva muri 2020-kandi muri buri kintu cyose, ubwoko butari bwo bwateje ubukererwe, guhungabanya umutekano, cyangwa gutsindwa imburagihe.
Kuki "Ubwoko" Ibyingenzi Kurenza Ingano cyangwa Umuvuduko
Umuvuduko ukabije wa 9-19 wa centrifugal uhindura umwuka muburyo butandukanye nubufana bubiri bwa centrifugal-ndetse no kuri RPM imwe hamwe nigitutu gihamye. Itandukaniro riri muri moteri ya geometrie, gushushanya, n'inzira yo mu kirere. Abimura inyuma-bagoramye bayobora imyuka yuzuye ivumbi itiziritse. Ibice byimbere-bigoramye bitanga amajwi menshi kumuvuduko muke uhagaze - ariko bikananirana byihuse mubidukikije. Imiyoboro ya radiyo-yicaye hagati yabo: gukora neza, kwihanganira cyane uduce duto, hamwe nubworoherane bwibikoresho bifite akamaro mugihe cyo kubungabunga ahantu hacanwa.
Twigeze gusimbuza umufana wananiwe imbere-uhetamye mumurongo wo gusiga imyenda hamwe nicyitegererezo cyinyuma. Igice cyambere cyamaze amezi 4. Agashya kamaze amezi 37 - nta gusimbuza gutwara, nta kunyerera umukandara, nta gutemba kw'umwuka. Kubera iki? Kuberako porogaramu isaba imivurungano mike, ntabwo CFM ntarengwa. Iri ni ryo tegeko rya mbere: guhuza na Ubwoko Kuri imyitwarire yo mu kirere, ntabwo ari imbonerahamwe.
Ubwoko bune bwibanze bwa Centrifugal-N'aho Batsinzwe
Abakoresha inganda ntibakeneye ibyiciro byamasomo. Bakeneye ibitekerezo byumvikana. Dore icyakora-kandi aho buri bwoko bugabanuka:
- Abafana basubiye inyuma (BC): Ibyiza kuri static-static, ubushyuhe bwinshi, cyangwa serivise yangirika-nkibikoresho bya desulfurizasi cyangwa umwuka wibanze. Impeller ya blade igarukira kure yo kuzunguruka. Imikorere igera kuri 82-87%. Ariko barasaba guhuza neza inlet; imiyoboro idahwitse itera kunyeganyega gusenya amazu. Moderi yacu ya BC (urugero, anti-ruswa ihindagurika hamwe na cashed ya FRP) irimo laser-ihuza inlet cones nkibisanzwe.
- Abakunzi b'imbere-bagoramye (FC). Ariko zirahagarara byoroshye hejuru ya 150 Pa ihagaze. Twabonye ibice bitatu bya FC binanirwa mumashanyarazi yo kugarura imiti kuko abashoramari birengagije umuvuduko ukabije wizamuka. Ntabwo zubatswe kubirwanya bihinduka.
- Abakunzi ba Radial-tip (RT). Icyuma kirambuye neza, kirwanya kwiyubaka. Impanuka yo hasi (72-78%) igurishwa kugirango yizewe. Muri progaramu imwe ya metallurgical umukiriya wa sinter cooler progaramu, abafana ba RT bagabanije amasaha atateganijwe kuri 63% ugereranije na BC.
- Dual-inlet abakunzi ba centrifugal: Imashini ebyiri kumutwe umwe, gushushanya umwuka kumpande zombi. Itanga urujya n'uruza rutagira asimmetrie. Nibyingenzi aho umwanya ufunganye ariko umwuka uhumeka ugomba kuguma uhagaze neza - nkibikoresho byo guhumeka umuyaga cyangwa sisitemu yo gusohora umwotsi. Ariko, barasaba gushiraho ishingiro rikomeye. Impinduka ya mm 2 ya fondasiyo yateje resonance mumushinga uheruka kugeza twongeyeho amakariso adashobora kwangirika.
Ibyo Cataloge itazakubwira
Bamwe bashobora kuvuga ko guhitamo ibikoresho birenze ubwoko bwimuka. Ariko twabonye abafana ba titanium hamwe no kurwanya ruswa neza birananirana kuko uwasunitswe inyuma-yagoramye ntashobora kwihanganira ivu ryipakurura. Ubwoko busobanura ibya fiziki. Ibikoresho bisobanura idirishya ryo kubaho.
Ukuri kutatu gukomeye kuva kumurima:
- Imirongo y'ingutu irabeshya. Umufana wagenwe kuri "12 kPa @ 25.000 m³ / h" afata uburyo bwiza bwo kwinjira. Inkokora nyayo-yisi inkokora, dampers, na filtri bigabanya imikorere ifatika 12-18%. Buri gihe ugerageze kurwego rwa sisitemu - ntabwo ari abafana gusa.
- Icyemezo kidashobora guturika (urugero, dⅠ ku birombe by'amakara) kireba inteko yuzuye - ntabwo ari moteri gusa. Moteri yemewe yahinduwe kugirango inzu itemewe. Ihuriro ryacu rya FBD ririmo ibicuruzwa bitarwanya ibicuruzwa hamwe ninzira zihamye zagenzuwe kuri GB 3836.1.
- Kuringaniza imbaraga ntabwo ari ubushake. Abafana ba BC bataringaniye baranyeganyega kuri 1,450 RPM. Kuri 2,900 RPM, ubwo busumbane bumwe bugwiza imbaraga inshuro enye. Buri mufana wa Hongcheng centrifugal ahura na ISO 1940 G2.5 kuringaniza-gupimwa, ntabwo byafashwe.
Uburyo bwo Guhitamo-Urutonde-rw'iminota itanu
Mbere yo gufungura urupapuro rwihariye, subiza ibi bibazo bitanu:
- Niki igitutu ntarengwa gihamye—Ntabwo ari impinga, ntabwo ari inyigisho? Gupima na manometero kuri enterineti, munsi yumutwaro wuzuye.
- Ese umuyaga urimo? abrasives, ubushuhe, cyangwa imiti? Niba ari yego, kura imbere-igoramye. Shyira imbere radial-tip cyangwa inyuma-igoramye hamwe na kote ikingira.
- Is umwanya? Dual-inlet ikiza ikirenge ariko igasaba gukomera. Inlet-imwe hamwe na inlet yagutse irashobora kuba yoroshye.
- Abakoresha bazahindura inshuro nyinshi? Inyuma-yagoramye ikora neza. Imbere-igoramye izamuka bitateganijwe munsi yumuvuduko wa 60%.
- Niki ikiguzi cyo gutsindwa? Gufunga inzu yo guteka bigura $ 18,000 / isaha. Iyishyure imbere yinyuma-igoramye + ihuriweho nogukurikirana ubushyuhe-bitarangiye kugirango bisanwe byihutirwa.
Ubwoko bwabafana ba Centrifugal ntabwo ari ibice bisimburana. Nibisubizo byubushakashatsi kubibazo byumubiri. Hitamo ubwoko bwubaha umwuka wawe, ibidukikije, hamwe nintego zawe zo hejuru - ntabwo ari hamwe nagatabo keza cyane.
