Ibikoresho byinganda ntibikeneye abafana basakuza-bakeneye umwuka mwiza. Iyo abakora mu birombe by'amakara, inganda z’imiti, cyangwa ibyumba byo gutekesha binubira urusaku ruhagarika itumanaho - cyangwa iyo amatsinda yo kubungabunga amakuru avuga ko yambaye igihe kitaragera biturutse ku kunyeganyega - intandaro ni gake “umwuka mwinshi.” Ni kenshi gukora nabi umuyaga muto-urusaku kwishyira hamwe: kudahuza umurongo uhagaze neza, rotor itaringaniye, cyangwa amazu yongerera resonance aho kuyitesha.
Twagerageje ibice birenga 47 bya axial na centrifugal mumashanyarazi atatu yumuriro wa Shandong - buriwese avuga "imikorere ituje." 11 gusa byujuje ISO 5801 imbaraga zamajwi yumutwaro wuzuye. Ibisigaye byarengeje 82 dB (A) kuri metero 1 - ntibyemewe hafi yumwanya wo kugenzura cyangwa kumasaha 8. Imikorere-yisi-yuzuye urusaku rwabafana ntabwo isobanurwa na catalog decibel ibisabwa. Bipimirwa mukugabanya umunaniro wa operateri, kubyara ubuzima, n'imbaraga zabitswe mugihe umufana atarwana ubwayo.
Niki Cyakora Umufana Mubyukuri-Urusaku-Hanze ya Label
Umufana wukuri-urusaku ruto atangirana na disipuline yindege-ntabwo itinda gusa RPM. Ikibazo cyo kubara icyuma: ibyuma 7-byuma byumuvuduko ukabije wa centrifugali bigabanya urusaku rwa tone kuri 6-9 dB na 5-bingana. Ariko blade geometrie yonyine irananirwa nta gukora neza. Twasanze 0,08 mm yiruka mumarushanwa ya 9-19 yumunywanyi yateje spike ya 12 dB kuri 1,750 Hz-ihuzagurika muburyo bwo kuvuga abantu. Niyo mpamvu kuringaniza imbaraga kuri G2.5 (kuri ISO 1940-1) ntabwo ari ngombwa. Ntabwo ari ibiganiro.
Imiterere ikwirakwiza urusaku. Inkingi ya gauge irumvikana nkingoma. Ibyatanzwe mu murima byerekana amazu ya titanium-abafana bigabanya kwanduza imiterere 40% ugereranije nicyuma gisanzwe cya karubone - ndetse no mu kirere kimwe. Ariko titanium ntabwo buri gihe ikenewe. Igishushanyo mbonera cyibice bibiri byubatswe hamwe nuburyo bugabanijwe muburyo bwo hagati butanga 9-11 dB (A) kunoza igice cyigiciro.
Amakosa yo kwishyiriraho sabotage niyo igishushanyo cyiza. Gutera igisenge cya axial umuyaga hejuru ya purline yoroheje? Ibyo bihindura igisenge cyose mukibaho cyumvikana. Turerekana reberi yitaruye-kandi tukayigenzura ukoresheje moteri yihuta mugihe cyo gutangira. Niba kunyeganyega kurenze 4.5 mm / s RMS yo gutwara amazu, twongeye gusuzuma sisitemu yose. Ntabwo ari umufana. Imigaragarire.
Ingufu Zitangwa Ntizitangwa-Yongerewe
Bamwe bakeka ko urusaku ruke bisobanura imbaraga nke. Ntibikwiye. Umufana udahuye neza yiruka kuri 62% mugihe ataka kuri 88 dB (A). Umuyaga uhuza neza urusaku ruke ukubita 81% kuri 67 dB (A) - kubera ko ikorera hafi yikirere cyayo cyo hejuru, ntikinizwe cyangwa kiremerewe.
Fata urukurikirane rwa FBD ruturika-rutanga umuyaga uhumeka. Igishushanyo-cyacyo cyo guhinduranya ibyiciro bibiri byimuka 32.000 m³ / h kuri 3,200 Pa ihagaze - ariko ikurura 18% munsi yumuvuduko ugereranije nicyiciro kimwe ihwanye ninshingano imwe. Kubera iki? Kugabanya igihombo cyizunguruka hagati yicyiciro kigabanya imivurungano-iterwa no gukurura. Umuvurungano muke bisobanura ubushyuhe buke, urusaku ruke, hamwe na kilowati ikenewe kuri 1.000 m³ / h.
Turabikurikirana mugihe nyacyo. Uruganda rumwe rwa sima rwongeye guhindura abafana batandatu 9-19 boiler hamwe n urusaku ruke. Kuzigama ingufu za buri mwaka: 1.2 GWh. Kugabanya urusaku kuri sitasiyo ikora: 14 dB (A). Igihe cyo kwishyura: amezi 11 - ntabwo biva mubucuruzi "butuje", ahubwo biva mubyiza byapima indege kandi bigabanya igihombo.
Guhitamo niho Cataloge isanzwe yananiwe
"Urusaku ruke" ntacyo bivuze rudafite imiterere. Umuyaga usohora umwotsi muri tunnel ugomba guceceka * mugihe * urwanya gaze ya 400 ° C. Umufana wa desulfurizasi ukeneye kurwanya ruswa * wongeyeho * sub-70 dB (A) hagati ya chloride yuzuye igihu. Ibice byo hanze birasenyuka hano.
Niyo mpamvu ibibazo byinganda bihuriweho. Mugihe umukiriya yari akeneye umufana wa titanium kubidukikije bya H₂S - kandi agasaba ≤65 dB (A) kuri metero 3 - ntitwakuye ibice. Twakoze imashini itera imbere mu nzu, dusudira amazu dukoresheje argon, dushyiramo ibyuma byometseho ceramic, kandi twemeza umusaruro wa acoustic ku kizamini cya anechoic. Igihe cyose cyo kuyobora: ibyumweru 14. Nta gutandukana ku rusaku, ubunyangamugayo, cyangwa gutanga.
Ibyingenzi byingenzi byo kwifashisha dukoresha burimunsi:
Gukuraho icyuma kuri sisitemu yihariye ya sisitemu Gushyira umurongo wa Acoustic Guhuza imirongo yiganje-ntabwo ari igipfukisho Gukuramo moteri gutandukanya electromagnetic hum kuva kunyeganyega kwa mashini Inzira yo kwemeza iturika ihujwe na IEC 60079-0 / 1/31 - ntabwo ari Bolt-on gusa Guhitamo Ibikurikira Bikurikira-Urusaku rwumufana: Igenzura rikorwa
Mbere yo gusobanura, baza ibibazo - hanyuma urebe ibisubizo hamwe na raporo y'ibizamini, ntabwo ari udutabo:
Imbaraga zijwi zapimwe kuri ISO 5801 - cyangwa umuvuduko wijwi gusa intera imwe? Ese umurongo wo gukora neza werekana impinga> 75% aho ukeneye gukora? Ese kwihanganira ubuzima bushingiye ku mutwaro L10 nyirizina - ntabwo ari amahame ya RPM? Bashobora gutanga igice cya gatatu NVH (urusaku-vibrasiya-ubukana) kwemeza kuboneza neza? Muri Zibo Hongcheng Fan Co., Ltd., buri mufana w’urusaku ruto rwoherejwe hamwe nicyemezo cyikizamini cya acoustic cyashyizweho umukono hamwe nikarita yuzuye yerekana - ntabwo ari ingingo imwe gusa. Twubaka aho ikirere cyujuje ibyangombwa: 9,000 m² yo gutunganya neza, kuringaniza imbaraga, no kugerageza imitwaro nyayo mubihe byinganda. Kuberako gukonjesha bucece bitagomba kuba ibintu byiza. Igomba kuba ishingiro ryimikorere itekanye, ikora neza, kandi irambye.
Kuri ba injeniyeri bapima intsinzi muri décibel birinze kandi kilowatts yazigamye - ntabwo metero kibe yimutse-igisekuru kizaza cya tekinoroji y’abafana y’urusaku rumaze gukora. Ntabwo ari muri laboratoire. Mu birombe. Mu nzu. Muri zone zirimo imiti. Aho kwiringirwa bidasezeranijwe. Byaragaragaye.
