Kunanirwa kwumuyaga wa rotor kunanirwa guhagarika umwuka-no mubucukuzi bwubutaka, bivuze guhita byangiza ubuzima, umusaruro, no kubahiriza amabwiriza. Twasimbuye rotor zirenga 217 hirya no hino muri FBD urukurikirane rw'ibisasu biturika bituruka mu birombe bya Shandong na Shanxi kuva mu 2022. Muri buri kintu cyose, icyabiteye nticyari ugusenyuka gitunguranye-byari byavuzwe ko kwambara byari bipfundikijwe no gukurikirana bidahuye, kwishyiriraho nabi, cyangwa kubitindaho. Aka gatabo kagaragaza ibyo tubona kurubuga: ntabwo ari théorie, ariko intambwe nyazo, igihe, nimbibi zitandukanya ibikorwa byumutekano no guhagarika ku gahato.
Iyo Gusimburwa Atari Ibiganiro-Ntabwo bisabwa gusa
Rotor yumuyaga uhumeka ikora munsi yubukanishi bukabije: kuzunguruka guhoraho kuri 1,450-22.980 rpm, guhura n ivumbi ryamakara yangiza, ubushuhe, hamwe nigare ryumuriro. Kunyeganyega hejuru ya 4.2 mm / s (RMS, ISO 10816-3 Zone C) ibimenyetso byerekana uburinganire bwa rotor - ntabwo ari kwambara gusa. Dupima buri munsi dukoresheje lazeri ya vibrometero mugihe cyoherejwe. Niba kunyeganyega kuzamuka 18% icyumweru-ku-cyumweru * na * isesengura ryerekana ibyiganje 1 × inshuro, gusimbuza rotor bitangira mumasaha 72. Gutegereza ibice bigaragara cyangwa gusya byumvikana gutumira gutsindwa gukabije. Rotors mu bafana ba FBD-6.3 (dⅠ) yananiwe guhinduka hagati yamasaha 14,200 yo gukora nta guhinduranya imbaraga-ndetse no "gusoma" byanditse neza.
Inzira enye zo gufata neza Protokole Irinda 91% ya Kunanirwa kwa Rotor
Dushyira mubikorwa uruhererekane kuri buri kibanza cyamabuye aho iwacu umuyaga uhumeka rotor ibice bikora:
- Icyiciro cya 1 - Gusuzuma mbere yo gukuraho: Hagarika ingufu, funga tagi hanze (LOTO), hanyuma urebe niba voltage zero. Koresha icyerekezo cyerekana ikarita yerekana ikarita ya hub na blade-irenga 0,12 mm yerekana ihinduka rihoraho.
- Icyiciro cya 2 - Kugenzura gusenya: Kuraho icyuma mbere - ntabwo ari hub. Koresha Calibrated torque wrenches (ntabwo ari ibikoresho byingaruka) yashyizwe kuri 85 N · m kubifata M12 kumurongo wa FBD. Kwibagirwa iyi ntambwe irwanya hub flange kuri 63% ya rotor yibutswe.
- Icyiciro cya 3 - Gusubiramo neza: Sukura ibyuma birenze urugero muri pH-itabogamye. Kugenzura buri kirere cyogupima ubujyakuzimu> 0,08 mm (bipimwa nuburebure bwa digitale). Simbuza icyuma icyo aricyo cyose isuri irenga 12% yubugari bwumwimerere.
- Icyiciro cya 4 - Kuringaniza imbaraga: Kuringaniza kugeza kuri G2.5 amanota kuri ISO 1940-1. Ntuzigere usimbuka ibi - ndetse na rotor nshya. Laboratwari yacu yipimishije yasanze 74% byabasimbuye "off-the-shelf" barenze 5.1 mm / s kunyeganyega mbere yo kuringaniza.
Kuki "Nka Kera" Nibeshya cyane
Abakoresha bamwe batumiza rotor imwe kugirango birinde ibisabwa. Ariko umunaniro wibintu ntusubira inyuma. Rotor yakoresheje amezi 18 mumurongo muremure wa metani ifite impinduka za microstructural ntagenzura ryerekanwa. Ubu dutanga rotor zose zasimbuwe hamwe na seritifika yubushyuhe bwo kuvura hamwe nicyiciro cyihariye cyingirakamaro (min. 725 MPa umusaruro wa Q345B ibyuma). Rotor ya Titanium-kubidukikije byangiza-bisaba ASTM B265 yuzuye yo kugenzura icyiciro cya 2. Gukoresha ibice bidafite ibyemezo byubusa ibyemezo biturika (GB 3836.1–2021) kandi bigatera kwiyandikisha byemewe-bitwara $ 12,000 + niminsi 17 yo kumanura.
Ikiguzi-Cyisi Igiciro & Igihe cyo Gusenyuka
Gusimbuza ikirunga umuyaga wa rotor ntabwo ari ikiguzi cyonyine. Dore icyimura inshinge:
- Akazi: Amasaha 6.5 byibuze (harimo LOTO, kwisuzumisha, kuringaniza, kugerageza). Abatekinisiye kabuhariwe gusa-ntabatoza kumirimo-ikomeye.
- Igihano cyo hasi: Kuri toni miliyoni 1.2 yumusaruro / kumwaka, buri saha kumurongo igura amadolari 8.400 yumusaruro wabuze + $ 2100 mubihano bya sisitemu yo guhumeka (kubitegeko byumutekano wintara).
- Ibice: Rotor isanzwe ya karubone-ibyuma: $ 2,150. Rotor-yerekana titanium rotor: $ 9.800. Igihe cyo kuyobora: iminsi 11 yakazi isanzwe; Iminsi 4 yerekana (hamwe no kwishyura mbere).
- Igiciro cyihishe: Gusimbuza kutaringaniza bitera kunanirwa imburagihe mu mezi 3.2 ugereranije - wongeyeho $ 1,320 mubice bitateganijwe hamwe nakazi.
Turakurikirana ibi bipimo mumasezerano 47 akora. ROI yo gusimbuza rotor buri saha 12,000? 3.8x kugabanya guhagarika umwuka uteganijwe. Ibyo ntabwo ari ukubungabunga-ni ubwishingizi bukora.
Ijambo ryanyuma: Umutekano utangirira kuri Rotor
A umuyaga uhumeka rotor ntabwo ikoreshwa. Numutima wa kinetic ya sisitemu yogufasha ubuzima munsi yubutaka. Gusoma kwinyeganyeza byose, buri torque igaragara, buri cyiciro cyo kuringaniza kibaho kuko umuntu yigeze gutegereza igihe kirekire - kandi yishyuye amafaranga arenze. Zibo Hongcheng Fan Co., Ltd. yubaka rotor kugeza kuri GB / T 1236 na ISO 5801 - ariko ibipimo ntacyo bivuze nta kubahiriza ibihano. Tangira uyumunsi: kurura ukwezi gushize. Niba hari igice cyerekana ibyasomwe bitatu bikurikiranye hejuru ya 3.5 mm / s, gahunda yo gusimbuza nonaha. Ntabwo ari igihembwe gitaha. Ntabwo nyuma yubugenzuzi bukurikira. Noneho. Kuberako mugucukura amabuye y'agaciro, intera yamakosa ipimwa muri milimetero-n'amasegonda.
