Ukungaphumeleli kwe-rotor ye-ventilation ye-air kumisa ukuhamba komoya-kwaye kwimigodi engaphantsi komhlaba, oko kuthetha umngcipheko wokuphila ngokukhawuleza, imveliso, kunye nokuthotyelwa komthetho. Siye satshintsha ngaphezu kwe-217 rotors kulo lonke uchungechunge lwe-FBD abalandeli be-axial be-explosion-proof e-Shandong kunye nemigodi yamalahle yase-Shanxi ukususela ngo-2022. Kuzo zonke iimeko, unobangela wengcambu awuzange uqhekeke ngokukhawuleza-kwakuqikelelwa ukunxiba okufihliweyo ngokubeka iliso okungahambelaniyo, ukufakwa okungahambi kakuhle, okanye ukugcinwa kwe-deferred. Esi sikhokelo sichitha into esiyibonayo kwisiza: hayi ithiyori, kodwa amanyathelo achanekileyo, ixesha, kunye nemida eyahlula ukusebenza ngokukhuselekileyo kukuvalwa ngenkani.
Xa Ukutshintshwa Kungaxoxiswana—Akunconyelwa Kuphela
I-rotor ye-fan ventilation yasemgodini isebenza phantsi koxinzelelo olugqithisileyo lomatshini: ukujikeleza okuqhubekayo kwi-1,450-2,980 rpm, ukuvezwa kuthuli lwamalahle abrasive, ukufuma, kunye nokuhamba ngebhayisikile eshushu. I-Vibration spikes ngaphezu kwe-4.2 mm / s (RMS, ISO 10816-3 Zone C) isignali yokungalingani kwe-rotor-kungekhona nje ukuthwala ukunxiba. Silinganisa oku yonke imihla sisebenzisa i-laser vibrometers ephathwayo ngexesha lokunikezelwa kweshifti. Ukuba i-vibration ikhwela i-18% ngeveki * kwaye * uhlalutyo lwesigaba lubonisa i-1 × i-frequency, ukutshintshwa kwe-rotor kuqala kwiiyure ze-72. Ukulinda iintanda ezibonakalayo okanye ukucola okuvakalayo kumema ukusilela okuyingozi. IiRotors kwi-FBD-6.3 (dⅠ) abalandeli baye basilela phakathi kwe-shift emva kwe-14,200 yeeyure zokusebenza ngaphandle kokulungelelaniswa okuguquguqukayo-nokuba "ulungile" ukufundwa.
IProthokholi yokuGcinwa kweZine eziNqanda i-91% yokuFayiswa kweRotor
Sinyanzelisa olu landelelwano kuyo yonke indawo yemigodi apho yethu i-rotor yefeni yokufaka umoya yam iiyunithi ziyasebenza:
- Inqanaba loku-1 - Ukuxilongwa kwangaphambili kokususwa: Vala amandla, tshixa ithegi ngaphandle (LOTO), emva koko uqinisekise i-voltage engu-0. Sebenzisa isalathisi sokudayela kwimephu yokuphuma kwi-hub kunye neengcebiso ze-blade-edlula i-0.12 mm ibonisa ukuguqulwa okusisigxina.
- Inqanaba lesi-2 - Ukuqhaqha okulawulwayo: Susa iiblades kuqala-hayi hub. Sebenzisa i-calibrated torque wrenches (hayi izixhobo zempembelelo) zisetelwe ku-85 N·m kwi-M12 fasteners kuthotho lwe-FBD. Ukulibala eli nyathelo liphazamisa i-hub flange kwi-63% yee-rotors ezikhunjulweyo.
- Inqanaba lesi-3 -Ukulungiswa kwakhona ngokuchanekileyo: Amagqabi acocekileyo acocekileyo nge-ultrasonically kwi-pH-neutral solvent. Hlola i-airfoil nganye ubunzulu bomgodi>0.08 mm (ilinganiswe ngegeyiji yobunzulu bedijithali). Buyisela nayiphi na incakuba ngokhukuliseko olungaphezulu kwe-12% yobukhulu boqobo.
- Inqanaba lesi-4 – Ulungelelwaniso olunamandla: Ibhalansi ukuya kwibakala le-G2.5 nge-ISO 1940-1. Ungaze utsibe oku-nokuba ii-rotors ezintsha. Ilebhu yethu yovavanyo ifumene i-74% yokutshintshwa kwe-"off-the-shelf" idlule i-5.1 mm / s vibration phambi kokulinganisa.
Kutheni “NjengeNkonde Endala” Yeyona mpazamo iXabiso kakhulu
Abanye abaqhubi bayalela iirotor ezifanayo ukunqanda ukufaneleka. Kodwa ukudinwa kwezinto eziphathekayo akunakuguqulwa. I-rotor eqhube iinyanga ze-18 kwitonela ye-methane ephezulu ineenguqu ze-microstructural akukho zibambe zokuhlola ezibonakalayo. Ngoku sinikezela zonke iirotor ezitshintshileyo kunye nezatifikethi ezilandelekayo zokunyanga ukushisa kunye ne-batch-specific-specific tensile data (min. 725 MPa isivuno se-Q345B steel). I-Titanium rotors-yeendawo zegesi ezinobungozi-zifuna ukuqinisekiswa okupheleleyo kwe-ASTM B265 yeBanga lesi-2. Ukusebenzisa iindawo ezingaqinisekisiweyo ze-voids isiqinisekiso sobungqina bokudubula (GB 3836.1-2021) kwaye ibangela ukuqinisekiswa okunyanzelekileyo-kubiza i-$ 12,000 + kunye ne-17 yeentsuku zokuphumla.
Iindleko zokwenyani zeHlabathi kunye noKuqhekeka koMda weXesha
Ukutshintsha i-rotor ye-fan yokupholisa emgodini ayikho malunga nenxalenye yeendleko zodwa. Nantsi eyona nto ishukumisa inaliti:
- Umsebenzi: 6.5 iiyure ubuncinane (kubandakanywa LOTO, diagnostics, balancing, retest). Amagcisa anezakhono kuphela-akukho bafundi kwimisebenzi ebaluleke kakhulu.
- Isohlwayo sexesha lokuphumla: Kwimveliso ye-1.2 yezigidi zeetoni / ngonyaka, iyure nganye engaxhunyiwe kwi-intanethi ixabisa i-$ 8,400 kwimveliso elahlekileyo + i-$ 2,100 kwizohlwayo zenkqubo yokungenisa umoya (ngomgaqo wokhuseleko wephondo).
- Amacandelo: I-rotor ye-carbon-steel eqhelekileyo: i-$ 2,150. Ukuqhuma-ubungqina be-titanium rotor eqinisekisiweyo: $ 9,800. Ixesha lokukhokela: Iintsuku ze-11 zokusebenza eziqhelekileyo; 4 iintsuku express (kunye nentlawulo yangaphambili).
- Ixabiso elifihliweyo: Ukutshintshwa okungenakulungelelaniswa kubangela ukungaphumeleli kokuthwala kwangaphambili kwiinyanga ze-3.2 ngokuqhelekileyo-ukongeza i-$ 1,320 kwiindawo ezingacwangciswanga kunye nomsebenzi.
Silandelela ezi metrics kwiikhontrakthi ezisebenzayo zasemgodini ezingama-47. I-ROI yokutshintshwa kwe-rotor ehleliweyo rhoqo kwiiyure ze-12,000? 3.8x ukuncitshiswa kokuphuma komoya okungacwangciswanga. Oko akusiyo isondlo-yi-inshurensi yokusebenza.
Igama lokugqibela: Ukhuseleko luqala kwiRotor
A i-rotor yefeni yokufaka umoya yam ayisiyonto ityiwayo. Yintliziyo yekinetic yenkqubo yakho yokuxhasa ubomi phantsi komhlaba. Lonke ukufundwa kokungcangcazela, yonke i-torque spec, ibakala ngalinye lokulinganisa likhona ngenxa yokuba umntu walinda ixesha elide-kwaye wabhatalwa ngaphezulu kwemali. I-Zibo Hongcheng Fan Co., Ltd. yakha i-rotors kwi-GB / T 1236 kunye nemigangatho ye-ISO 5801-kodwa imigangatho ayithethi nto ngaphandle kokubulawa okuqeqeshekileyo. Qala namhlanje: tsala iilogi zokungcangcazela kwinyanga ephelileyo. Ukuba nayiphi na iyunithi ibonisa ufundo oluthathu olulandelelanayo ngaphezu kwe-3.5 mm/s, ishedyuli yokutshintshwa ngoku. Hayi kwikota elandelayo. Hayi emva kophicotho olulandelayo. Ngoku. Ngenxa yokuba ekungeneni komoya osemigodini, umda wempazamo ulinganiswa ngeemilimitha—nemizuzwana.
