Ukusebenza kwabalandeli bokucima umlilo akulinganiswa ngama-decibel noma amajika okugeleza komoya kuphela—kukalwa ngamasekhondi alondoloziwe, ukubonakala kubuyiselwe, futhi izimpilo zivikelekile. Lapho intuthu iklinya izitebhisi, igcwalisa umhubhe, noma ingubo yokulala ekamelweni lokulawula isitshalo samakhemikhali, umoya ovamile awusebenzi. Okusebenzayo kuyinhloso eyakhelwe fan Firefighting: ivolumu ephezulu, ukuthunyelwa ngokushesha, yakhelwe isiphithiphithi—hhayi ukunethezeka.
Kungani “Ukusulwa Kwentuthu Esheshayo” Kudinga Okungaphezu Kwe-CFM Nje
Sikubonile esizeni: abasebenzi bekhipha amapayipi angamamitha angama-30 kuphela bathola abalandeli babo be-CFM abangu-15,000 bemile ekuphumeni okungu-40% ngenxa yokuthi umfutho ongemuva unyuke eduze komnyango womlilo. Ukungena komoya okucisha umlilo kwangempela akuhluleki kusukela ekucacisweni okuphansi—kodwa ekwakhiweni okungafani. A iqiniso fan Firefighting kufanele ilethe izinto ezintathu ngesikhathi esisodwa: high static pressure (ukuphusha umoya emiseleni emide, ekhiyiwe), i-torque esheshayo (akukho ukubambezeleka kokwenyuka lapho amandla eshaya), futhi ukubekezelelana okushisayo okuqinile (ilokhu isebenza ku-80°C kuma-ambient, hhayi nje ku-40°C).
Uchungechunge lwe-FBD (dⅠ) oluvikela ukuqhuma oluphikisayo lwe-axial flow fan—luvivinywe endaweni yokutakula emayini yamalahle—lufakazela lokhu. Idizayini yayo ye-double-motor, i-counter-rotating impeller ikhiqiza ingcindezi emile engu-3,200 Pa ku-22,000 m³/h. Lokho akulona ithiyori. Ekulingiseni komlilo kamhubhe ka-2023 e-Shandong, kususe u-90% wentuthu ebonakalayo engxenyeni engamamitha angu-180 ngaphansi kwamasekhondi angu-97—ngenkathi igcina ukugeleza komoya okuzinzile naphezu kokukhuphuka kwezinga lokushisa lokungena ku-120°C. Abalandeli be-axial abajwayelekile baminyaniswe ku-65°C.
Yini Eyenza Umlandeli “Indawo Yomlilo Ilungele”—Hhayi nje “Ibanga Lemboni”
Abanye abakhiqizi bafaka ilebula noma yimuphi umlandeli we-heavy-duty ngokuthi "owokucima umlilo." Lokho kuyingozi ukwenza lula. Ukungena komoya endaweni yomlilo kudinga ukuhwebelana okuzuzwe kanzima:
Isitifiketi sokuvikela ukuqhuma asikhethi-akuxoxiswana ngayo ezindaweni zomhwamuko ovuthayo. Isilinganiso se-dⅠ sihlanganisa izindawo zothuli lwe-methane/amalahle nge-GB 3836.1–2021 ngayinye, hhayi nje ilebula evamile “ephephile”. Isisindo uma kuqhathaniswa nokusetshenziswa: Isivutheli se-centrifugal esingu-120 kg singahambisa umoya owengeziwe—kodwa uma izicishamlilo ezimbili zingakwazi ukuliphakamisela elolini elinesitebhisi ngaphansi kwamasekhondi angu-45, akusizi ngalutho. Okubaluleke kakhulu umgomo fan Firefighting amayunithi ahlala ngaphansi kuka-42 kg ngaphandle kokudela ubuqotho be-impeller. Isixhumi esibonakalayo samapayipi sibaluleke ngaphezu kwamandla amahhashi. Sishintshe abalandeli safaka ama-specs afanayo kodwa i-geometry ye-flange ehlukile—futhi sinqamule isikhathi sokusetha ngo-60%. Ukuxhumanisa ngokushesha, ama-tapered, ama-self-sealing couplings aqeda ukuvuza okopha u-25-40% wokugeleza komoya okusebenzayo. Yingakho i-Zibo Hongcheng Fan Co., Ltd. ihlanganisa ukuhambisana kwepayipi esigabeni sayo sobunjiniyela—hhayi njengokucatshangelwa kamuva. Amamodeli abo e-FBD ahamba namapuleti okufakwayo ahambisana ne-ISO 5211 kanye namakholola ajwayelekile angama-630 mm. Awekho ama-adaptha. Akukho ukuthuthukisa inkambu.
Ukwenza Ngokwezifiso Akuyona Ukunethezeka—Kungumehluko Phakathi “Kwemisebenzi” kanye “Nokulondoloza”
"I-off-the-shelf" ayivamile ukufana nezigcawu zomlilo. Indawo yokucwenga idinga ukumelana nokugqwala ngokumelene nentuthu egcwele i-H₂S. I-textile mill idinga izigxivizo ze-aluminium ezivikela inhlansi. Isiteshi esingaphansi komhlaba sidinga ukusebenza komsindo ophansi kakhulu ongaphansi kuka-72 dB(A) kumamitha angu-3—ngaphandle kokusika ukugeleza komoya.
Iklayenti elilodwa—izicishamlilo zikamasipala eJiangsu—lidinga a fan Firefighting ezingase zisebenze ngokuqhubekayo amahora ama-4 ngomthwalo ongu-100% kuyilapho usinda ekuchayekeni okuphindaphindiwe emanzini. Izindlu ezijwayelekile ze-IP54 zehlulekile phakathi nemizuzu engama-90. Isixazululo? Izindlu zangokwezifiso ze-titanium-alloy (hhayi i-titanium egcwele—enqabela izindleko), ama-motor seal anesilinganiso se-IP67, nezixhumi zensimbi engagqwali. Ilethwa ngezinsuku zokusebenza eziyi-11. Ihlolwe emijikelezweni yokucwiliswa emanzini eyimizuzu engu-120. Isasebenza ngemva kwezinyanga ezingu-18.
Lobu buchule buvela ekwenzeni imishini yasendlini, ukulinganisa okunamandla, nokuhlola ukulayisha—konke ngaphansi kophahla olulodwa. Akukho ukubambezeleka kokukhishwa kwemisebenzi. Akukho ukudonsa okucacisiwe phakathi komdwebo wobunjiniyela neyunithi yokugcina.
Ukukhetha Umlandeli Wakho Olandelayo Wokulwa Nomlilo: Amasheke Amathathu Angaxoxiswana
Ngaphambi kokuthi uphume ngemvume kunoma iyiphi iyunithi, qinisekisa lokhu—ephepheni futhi mathupha:
Ijika lengcindezi emile ku-100% RPM, hhayi nje i-CFM ephezulu. Cela ishadi lejika le-P-Q eligcwele—hhayi nje inombolo yesihloko. Uma bengeke babelane ngakho, hamba. Idatha yomhlaba wangempela yokwehlisa ukushisa: Kwehla kangakanani ukugeleza komoya ku-70°C ku-ambient? Ku-100°C? Ayihloliwe “ku-100°C”—kodwa “igcina ukugeleza komoya okungu-≥92% okulinganiselwe ku-100°C ambient imizuzu engu-120.” Imibhalo yenkonzo yasensimini: Ingabe imanuwali yokulungisa ibhalelwe izicishamlilo—hhayi ochwepheshe basefekthri? Ingabe ihlanganisa imininingwane ye-torque yazo zonke iziqinisi, ukubekezelelwa kokuqondanisa kwemigudu, kanye nokuxilongwa kwemodi yokwehluleka (isb., “ukudlidliza okungaphezu kuka-4.2 mm/s RMS ngo-1,750 rpm = ukugqokwa kokuthwala >15%)? A fan Firefighting akukaze kube "imishini nje." Kungukuphindaphinda amandla. Ishintsha ukukhathala kokushisa kube ukuphuma okulawulwayo. Iguqula ukubonakala okuyiziro kube imigqa yokubona ephathekayo. Inikeza abaphathi bezehlakalo imizuzu-hhayi imizuzwana-ukunquma.
I-Zibo Hongcheng Fan Co., Ltd. iwakha ngaleyo ndlela—hhayi ukuze acacise amashidi, kodwa ngokweqiniso le-fireground. Indlela yabo ibonisa iqiniso elilula: uma imizuzwana ibala, ukwethembeka akusona isici. Iwukuphela kwemethrikhi ebalulekile.
