Mine ventilation fan gucecekesha ntabwo ari inyongera gusa-ni ikintu gikomeye kigena niba ikirombe cyujuje imipaka y’urusaku rw’akazi, kikirinda ibihano byateganijwe, kandi kigakomeza kuba maso mu bakozi mu gihe cy’amasaha 12. Twabonye abakozi bo munsi y'ubutaka bavuga tinnitus nyuma y'amezi atandatu bahuye n'urusaku rw'abafana batanduye kuri 92 dB (A); twapimye ibitonyanga byo mu kirere bya 18% mugihe icecekesha cyashyizwe munsi cyangwa cyinjijwe nabi mubikorwa. Niyo mpamvu abajenjeri muri Zibo Hongcheng Fan Co., Ltd. bavura buriwese umuyaga uhumeka umuyaga nk'igice cya sisitemu - ntabwo ari agasanduku kihariye.
Impamvu Abicecekera Bisanzwe bananirwa munsi yubutaka
Benshi mu bacecekesha ibintu bifata ubwinshi bwikirere, umwuka mwiza wo gufata, hamwe nubushyuhe bwibidukikije buri munsi ya 40 ° C. Ibirombe nta na kimwe bitanga. Umwuka wuzuye umukungugu ufunga itangazamakuru ryakira ibyumweru. Ubushuhe buhebuje bwangiza imbere. Umuvuduko utunguranye uva mubintu biturika guhangayikishwa n'ingingo. Ahantu hashobora guturika harasaba ibikoresho bidacana - inzu ya aluminiyumu ifite ibyuma bidafite ingese, ntabwo ibyuma bya karubone bifatanye. Abafana bacu ba seriveri ya FBD basanzwe biruka kuri 3,200 Pa static pressure; gucecekesha bigomba gukemura ibyo nta resonance yubaka cyangwa gutandukana gutemba. Umukiriya umwe muri Shanxi yasimbuye icecekesha rusange hamwe nigice cyateguwe cyabigenewe - hanyuma agabanya urusaku rwabafana kuva kuri 104 dB (A) kugeza kuri 79 dB (A) mugihe akomeza ± 1,2% byimyuka ihumeka hagati ya 200-1.800 m³ / min.
Ibipimo bine bidashidikanywaho
Imikorere umuyaga uhumeka umuyaga igomba kuba yujuje ibi bipimo bine - nta na kimwe kidasanzwe:
- Icyemezo-giturika: Ibice byose byacukurwamo amakara bitwara dⅠ igipimo cya GB 3836.1–2021; nta guhuzagurika ku gufatana-kwangirika cyangwa gukomera
- Kugenzura igitutu: Max ΔP ≤ 85 Pa ku kigero cyagenwe - kurenga ibi bihatira abafana gukora cyane, kongera ingufu no kwambara imashini
Twemeje buri gishushanyo dukoresheje protocole yikizamini ISO 7235, ntabwo ari uwabikoze gusa. Ibyukuri-byukuri amakuru arenze impapuro za laboratoire.
Kwishyira hamwe Niho Imikorere Yatakaye-cyangwa Yatsinze
Acecekesha akora gusa iyo ihagaze neza. Kubishyiraho bitaziguye kuruhande rwabafana bitera imivurungano ihakana kimwe cya kabiri cyayo. Turerekana byibuze imiyoboro igororotse ikora: diametero 5 z'umuyoboro hejuru, 3 kumanuka. Kubakunzi ba axial nka FBD-NO.6.3, twinjiza acecekesha abafana ubwabo - gukuraho igihombo cyo guhuza no kugabanya ikirenge cya 37%. Imishinga ya retrofit akenshi yirengagiza ihererekanyabubasha: gucecekesha udacecekesha guhindura imiyoboro ihindura amajwi. Ibice byacu birimo ibyiciro bibiri bya elastomeric byapimwe kuri 0.5-22.000 Hz yo kwigunga - byagenzuwe no gusoma byihuta mbere na nyuma yo kwishyiriraho.
Kwiyubaka ntabwo ari plug-na-gukina. Dutanga urubuga rwihariye rwa torque, kwihanganira guhuza (± 0.15 mm), no kugenzura urutonde. Umushinga umwe wa tunnel muri Yunnan watsinzwe ibizamini byurusaku rwambere kubera ko ibyuma bya ankeri bitigeze bihangayikishwa na 75% byimbaraga-bitera micro-traffic na 12 dB re-imirasire. Gukosora? Retorque + ongeramo amabati. Bikorewe mu minota 90.
Kwishyira ukizana nta guhuzagurika
Gucecekesha bisanzwe ntibikunze guhuza imiterere igoye. Twubatsemo ibice bifite inset ya offset, 45 ° zicururizwamo, hamwe no kuzimya umuriro-byose bitarenze ibyumweru 4. Umukiriya wa metallurgical yari akeneye kurwanya ruswa kugirango H exhaustS ikungahaye cyane: twakoresheje titanium alloy baffles hamwe na PTFE yuzuye acoustic yuzuye, tugera ku gihombo 32 dB (A) cyo kwinjiza 500 Hz mugihe twarokotse igeragezwa ryamasaha 1200. Nta kintu cyimigabane gishobora gukora ibyo. Custom ntabwo bivuze gutinda. Umurongo wamazu wa CNC ugoramye ukora ibice bigera kuri mm 2000; dinamike iringaniza ibera munzu kuri toni 3 yubushobozi. Buri gice cyoherejwe hamwe na raporo yuzuye yikizamini: octave-band attenuation curve, igitutu cyamanutse nigishushanyo mbonera, hamwe nimpamyabushobozi.
Zibo Hongcheng Fan Co., Ltd yubaka umuyaga uhumeka umuyaga sisitemu - ntabwo ari ibice. Turabashiraho aho bazakorera mubyukuri: amazi, umukungugu, umuvuduko mwinshi, ibidukikije-bikomeye. Kuberako guceceka munsi yubutaka bitacecetse-ni kwizerwa mubikorwa, kurinda kumva, no guhumeka neza.
