Mine ventilation fan isithulisi ayisongezo nje-lilungu elibalulekileyo elimisela ukuba umgodi uyahlangabezana nemida yengxolo yomsebenzi, uphepha izohlwayo ezilawulayo, kwaye ugcina ukuphaphama kwabasebenzi kwiiyure ze-12. Siye sabona abasebenzi bangaphantsi komhlaba bebika i-tinnitus emva kweenyanga ezintandathu zokuvezwa kwingxolo engapheliyo yabalandeli kwi-92 dB (A); siye salinganisa ukuhla kwe-airflow ye-18% xa izithulisi zazingaphantsi okanye zihlanganiswe kakubi kumbhobho. Yiyo loo nto iinjineli eZibo Hongcheng Fan Co., Ltd. ziphatha yonke into isithulisi sefeni yefeni yam njengenxalenye yenkqubo-hayi ibhokisi ezimele.
Kutheni izithulisi ezisemgangathweni zisilela phantsi komhlaba
Uninzi lwezithulisi ezingaphandle kweshelufu zithatha ukuxinana komoya okuzinzileyo, umoya ococekileyo ongenayo, kunye namaqondo obushushu angaphantsi kwama-40°C. Imigodi ayihambisi nanye kwezo. Umoya ozele luthuli uvala imidiya yokufunxa kwiiveki. Ukufuma okuphezulu konakalisa iibhilidi zangaphakathi. Uxinzelelo olukhawulezileyo olusuka kwiziganeko zoqhushumbo lucinezela amalungu adityanisiweyo. Kwaye iindawo ezikhusela uqhushumbo zifuna izinto ezingatshisiyo-izindlu ze-aluminiyam ezinentsimbi yangaphakathi, hayi intsimbi yekhabhoni enezibilini. Abalandeli bethu bechungechunge be-FBD bahlala beqhuba kuxinzelelo lwe-3,200 Pa static; izithulisi maziyiphathe loo nto ngaphandle kwe-resonance buildup okanye ukwahlukana kwamanzi. Omnye umxhasi e-Shanxi wathatha indawo yesithulisi segeneric kunye neyunithi yethu eyenzelwe isiko-kwaye unqumle ingxolo ye-fan-end ukusuka kwi-104 dB (A) ukuya kwi-79 dB (A) ngelixa igcina i-± 1.2% ukuhambelana komoya kuyo yonke i-200-1,800 m³ / min uluhlu.
Iikhrayitheriya zoYilo ezine ezingaThethwayo
Umsebenzi osebenzayo isithulisi sefeni yefeni yam kufuneka yanelise ezi khrayitheriya zine—akukho miqobo:
- Isiqinisekiso sobungqina bokudubula: Zonke iiyunithi zemigodi yamalahle zinomlinganiselo we-dⅠ nge-GB 3836.1–2021; akukho kuyekelela kwiziqhoboshi ezimelana nentlantsi okanye ukuqhubeka kokumisa
- Ukomelela kothuli: Iimodyuli ze-acoustic ezibuyiselwayo ezine-3mm-thick perforated perforated steel stainless ijonge-ivavanywe kwi-5 g/m³ yokulayisha uthuli iiyure ezingama-500+
- Ukuzinza kwe-Thermal: Iibhaffles ezingundoqo zilinganiswe ukusebenza ngokuqhubekayo ukuya kuthi ga kwi-85 ° C, ziqinisekiswe ngumfanekiso we-thermal ngexesha lokuvavanya umthwalo weeyure ezingama-72.
- Ulawulo lokuhla ngoxinzelelo: IMax ΔP ≤ 85 Pa kwisantya sokuhamba-ukugqithisa oku kunyanzela abalandeli ukuba basebenze nzima, ukonyusa ukusetyenziswa kwamandla kunye nokunxitywa koomatshini
Siqinisekisa uyilo ngalunye sisebenzisa iiprothokholi zovavanyo ze-ISO 7235, hayi nje amabango omenzi. Idatha yelizwe lokwenyani ibaluleke ngaphezu kwamaphepha elebhu.
Ukudityaniswa kulapho uMsebenzi walahleka-okanye uphumelele
Isithulisi sisebenza kuphela xa sibekwe ngokuchanekileyo. Ukuyixhoma ngokuthe ngqo kwindawo yokuphuma yabalandeli kudala isiphithiphithi esichasa isiqingatha sokuthomalalisa kwayo. Sicacisa ubuncinci bokuhamba ngokuthe tye: i-5 pipe diameters phezulu, i-3 ezantsi. Kubalandeli be-axial njenge-FBD-NO.6.3 yethu, sidibanisa i-silencer kwi-fan casing ngokwayo-ukuphelisa ilahleko yokudibanisa kunye nokunciphisa i-footprint nge-37%. Iiprojekthi ze-retrofit zihlala zijonge ukuhanjiswa kwe-vibration: izithulisi ezingadityaniswanga zijika umbhobho ube ziiradiyetha ezivakalayo. Iiyunithi zethu ziquka i-double-stage elastomeric mounts ezilinganiselwe kwi-0.5-2,000 Hz yodwa-iqinisekiswe ngokufundwa kwe-accelerometer ngaphambi nangemva kofakelo.
Ukufakela akuyoplagi kunye nokudlala. Sinikezela ngeempawu zetorque ezithe ngqo kwisiza, ukunyamezelwa kolungelelwaniso (±0.15 mm), kunye noluhlu lokutshekisha. Iprojekthi enye yetonela eYunnan yasilela kwiimvavanyo zokuqala zengxolo kuba iibholiti zeankile azizange zinyanzeliswe ukuya kuma-75% amandla okuvelisa-okubangela ukuhamba kwemicro kunye ne-12 dB yokukhanya kwakhona. Lungisa? Retorque + yongeza izikhonkwane zokucheba. Kwenziwe kwimizuzu engama-90.
Ukwenziwa ngokwezifiso Ngaphandle koKunyelisa
Izithulisi ezisemgangathweni azifane zilingane noyilo oluntsonkothileyo. Siye sakha iiyunithi ezine-offset inlets, ii-45 ° ze-angled angled, kunye nezidambisi mlilo ezidibeneyo-zonke kwiiveki ezi-4. Umxhasi we-metallurgical udinga ukuxhathisa ukubola kwi-H₂S-rich exhaust: sasebenzisa i-titanium alloy baffles kunye ne-PTFE-coated acoustic fill, ukuphumeza ilahleko yokufaka i-32 dB (A) kwi-500 Hz ngelixa sisinda kwi-1,200 yeyure yovavanyo lwetyuwa-spray. Akukho nto yesitokhwe enokuyenza loo nto. Isiko akuthethi kulibaziseka. Umgca wethu wezindlu ogobileyo we-CNC uphatha ukuya kuthi ga kwiiyunithi ze-2,000 mm ububanzi; ulungelelaniso oluguquguqukayo lwenzeka ngaphakathi endlwini kwisixhobo somthamo weetoni ezi-3. Iyunithi nganye ihamba ngeenqanawa ezineengxelo ezipheleleyo zovavanyo: i-octave-band attenuation curves, i-press drop drop vs. flow charts, kunye neziqinisekiso zemathiriyeli.
Zibo Hongcheng Fan Co., Ltd. yakha isithulisi sefeni yefeni yam iinkqubo-hayi amacandelo. Sizenza injineli apho ziya kusebenza khona: ezimanzi, ezinothuli, ezinoxinzelelo oluphezulu, iindawo ezikhuselekileyo zokhuseleko. Ngenxa yokuba ukuthula phantsi komhlaba akuthuli-kukuthembeka ekusebenzeni, ukukhuselwa kweendlebe, kunye nokuhamba komoya okungaphazanyiswa.
