Mine ventilation fan isithulisi akusona nje isengezo—kuyisici esibalulekile esinquma ukuthi imayini iyayifinyelela yini imingcele yomsindo wasemsebenzini, igwema izinhlawulo ezilawulayo, futhi igcina ukuqapha kwabasebenzi ngesikhathi sokushintshwa kwamahora angu-12. Sibone abasebenzi abangaphansi komhlaba bebika i-tinnitus ngemva kwezinyanga eziyisithupha zokuchayeka emsindweni wabalandeli ongancishisiwe ku-92 dB(A); silinganise ukwehla kokugeleza komoya okungu-18% lapho izithulisi zingasakhiwe ngaphansi noma zingahlanganiswa kahle nepayipi. Kungakho onjiniyela eZibo Hongcheng Fan Co., Ltd. bephatha yonke into isithulisi sefeni ye-ventilation njengengxenye yesistimu—hhayi ibhokisi elizimele.
Kungani Izithuli Ezivamile Zehluleka Ngaphansi Komshoshaphansi
Izithulisi eziningi ezingaphandle kweshalofu zithatha ukuminyana komoya okuzinzile, umoya ohlanzekile owuthathayo, namazinga okushisa angaphansi kuka-40°C. Izimayini azilethi ngisho nalezo. Ukugeleza komoya okugcwele uthuli kuvala imidiya emuncayo emavikini. Umswakama ophezulu ugqwalisa ukudideka kwangaphakathi. Ukucindezela okungazelelwe okuvela ezenzakalweni zokuqhuma kugcizelela amalunga ashiselwe. Futhi izindawo ezivikela ukuqhuma zifuna izinto ezingakhiqizi—izindlu ze-aluminium ezinensimbi engagqwali, hhayi insimbi ye-carbon ene-galvanized coating. Abalandeli bethu bochungechunge lwe-FBD bavame ukugijima ku-3,200 Pa static pressure; izithulisi kufanele zikuphathe lokho ngaphandle kwe-resonance buildup noma ukuhlukana kokugeleza. Iklayenti elilodwa e-Shanxi lishintshe isithulisi esijwayelekile lafaka iyunithi yethu eklanywe ngokwezifiso—futhi lanqamula umsindo wokuphela kwabalandeli ukusuka ku-104 dB(A) kuya ku-79 dB(A) kuyilapho ligcina ukufana kokugeleza komoya okungu-±1.2% kulo lonke ibanga elingu-200–1,800 m³/min.
Imibandela Emine Yomklamo Engaxoxiswana
A functional isithulisi sefeni ye-ventilation kufanele anelise lezi zindlela ezine—akukho okuhlukile:
- Isitifiketi sokuvikela ukuqhuma: Wonke amayunithi ezimayini zamalahle anesilinganiso esingu-dⅠ nge-GB 3836.1–2021 ngayinye; akukho ukuyekethisa ezibopheni ezingamelana nenhlansi noma ukuqhubeka kokubeka phansi
- Ukuqina kothuli: Amamojula we-acoustic ashintshekayo anensimbi engagqwali enogqinsi ongu-3mm ugqinsi—ahlolwe ngo-5 g/m³ ukulayisha uthuli amahora angu-500+
- Ukuzinza okushisayo: Ama-Core baffles alinganiselwe ukusebenza okuqhubekayo afika ku-85°C, aqinisekiswa isithombe esishisayo phakathi nokuhlolwa komthwalo wamahora angu-72
- Ukulawula ukwehla kwengcindezi: I-Max ΔP ≤ 85 Pa ekugelezeni okulinganiselwe—ukweqa lokhu kuphoqa abalandeli ukuthi basebenze ngokuzikhandla, bakhulise ukusetshenziswa kwamandla nokugqokwa kwemishini
Siqinisekisa umklamo ngamunye sisebenzisa izivumelwano zokuhlola ze-ISO 7235, hhayi nje izimangalo zomkhiqizi. Idatha yomhlaba wangempela ibaluleke kakhulu kunamashidi ngelebhu.
Ukuhlanganiswa Yilapho Ukusebenza Kulahleka khona-noma Kunqotshiwe
Isithulisi sisebenza kuphela uma sibekwe kahle. Ukuyikhweza ngqo ku-outlet yabalandeli kudala isiyaluyalu esilahla uhhafu wayo wokuthopha. Sicacisa amapayipi amancane aqondile: amadayamitha amapayipi angu-5 phezulu nomfula, 3 phansi komfula. Kubalandeli be-axial abafana ne-FBD-NO.6.3 yethu, sihlanganisa isithulisi ku-fan casing ngokwayo—siqede ukulahlekelwa okuhlanganisayo futhi sinciphise umkhondo ngo-37%. Amaphrojekthi we-retrofit ngokuvamile awanaki ukudluliswa kokudlidliza: izithulisi ezingahlangene zishintsha i-ductwork ibe ama-radiator anomsindo. Amayunithi ethu ahlanganisa izikhwebu ze-elastomeric ezinezigaba ezimbili ezilinganiselwe zokuhlukaniswa okungu-0.5–2,000 Hz—okuqinisekiswe ukufundwa kwe-accelerometer ngaphambi nangemuva kokufakwa.
Ukufaka akuyona i-plug-and-play. Sihlinzeka ngokucaciswa kwetorque eqondene nesayithi, ukubekezelelwa kokuqondanisa (±0.15 mm), kanye nezinhla zokuhlola zokugunyazwa. Iphrojekthi eyodwa yomhubhe e-Yunnan yehlulekile ukuhlolwa kokuqala komsindo ngenxa yokuthi amabhawodi okusetshenzwa kwehange awazange aqiniswe ukuze athole amandla angu-75%—okubangele ukunyakaza okuncane kanye nokusakazwa kabusha kwe-12 dB. Lungisa? Retorque + engeza izikhonkwane zokugunda. Kwenziwe emaminithini angu-90.
Ukwenza ngokwezifiso Ngaphandle Kokuyekethisa
Izithulisi ezijwayelekile azivamile ukufanela izakhiwo eziyinkimbinkimbi. Sakhe amayunithi anama-offset inlets, ama-engeli angu-45°, nezinciphisi zokucima umlilo ezihlanganisiwe—konke kungakapheli amaviki angu-4. Iklayenti le-metallurgical lidinga ukumelana nokugqwala kokukhipha umoya okucebile kwe-H₂S: sisebenzise ama-titanium alloy baffles anokugcwalisa i-acoustic ehlanganiswe ne-PTFE, sizuze ukulahlekelwa kokufakwa okungu-32 dB(A) ku-500 Hz ngenkathi sisinde ekuhlolweni kwesifutho sikasawoti samahora angu-1,200. Ayikho into yesitoko engenza lokho. Ukwenza ngokwezifiso akusho ukubambezeleka. Ulayini wethu wezindlu ogobile we-CNC uphatha amayunithi angama-2,000 mm ububanzi; ukulinganisa okuguquguqukayo kwenzeka ngaphakathi endlini kumshini womthamo wamathani angu-3. Yonke iyunithi ithunyelwa ngemibiko yokuhlola egcwele: amajika e-octave-band attenuation, ukwehla kwengcindezi ngokumelene namashadi agelezayo, nezitifiketi zezinto ezibonakalayo.
Zibo Hongcheng Fan Co., Ltd isithulisi sefeni ye-ventilation amasistimu—hhayi izingxenye. Sizinjiniyela zalapho zizosebenza khona ngempela: ezimanzi, ezinothuli, ezinengcindezi ephezulu, izindawo ezidinga ukuphepha. Ngoba ukuthula ngaphansi komhlaba akuthuli—ukwethembeka ekusebenzeni, ukuvikela ukuzwa, nokugeleza komoya okungaphazamiseki.
