Xoogayayaasha naxaasta ee Peru waxay ka shaqeeyaan halka hawadu dhuuban tahay oo silsiladaha wax soo iibsiga ay ka khafiifsan yihiin. Laga soo bilaabo Cerro Verde oo ku taal 2,700m ilaa Toromocho oo ku taal 4,600m, baahida loo yaqaan 'flotation impeller diffuser Peru' ayaa qaabeeya xaqiiqda ah in soosaarayaasha xeebuhu ay naadir yihiin: qayb kasta oo kayd ah oo timaada albaabka miinada Andean ayaa mar hore ka badbaaday 1,200-km oo ka soo fuulay dekedda Callao, oo hadda waa in ay hoos u dhigto heerkulka bambooyinku waxay ku riixaan 40% adkaha unugyo la dhisay markii Denver ay wali lahayd waaxdeeda injineernimada.
Peru wali waxay waddaa in ka badan unugyada sabbeynta Denver DR iyo Sub-A marka loo eego waddan kasta oo ka baxsan Mareykanka. At Antamina, Cerro Verde, iyo daraasiin ka mid ah hawlaha polymetallic-heer dhexe, kooxda dayactirka codsigooda qaybaha ma odhan "rotor" - waxa ay leedahay "impeller." Qaybta taaganna maaha "stator" - waa "diffuser." Ka hel ereybixinta khaldan jawaabta RFQ, oo waxaad hadda u sheegtay iibsadaha inaadan garanayn qalabkooda. Khadka alaabtayadu waxay dabooshaa taxanaha Denver DR iyo Sub-A oo buuxa, oo lagu daray moodooyinka Metso TankCell ee hawlgallada dib loo cusboonaysiiyay - dhammaantoodna waxay u kala horreeyaan tiro badan oo leh qaabaynta cimilada qabow ee polyurethane sida caadiga ah.
Codsiga Matrix: Muuqaalka Macdanta Gaarka ah ee Peru
1. Quudhiyeyaasha waaweyn ee Polymetallic (Cerro Verde, Antamina, Las Bambas)
Yaa arrintu khusaysaa: Kooxaha wax soo iibsiga ee dhexe ee maamula noocyada kala duwan ee maraakiibta sabbaynaya moodooyinka badan ee qaar ka mid ah hawlgallada naxaasta-zinc ee adduunka ugu waaweyn.
Dhibaatada: Antamina waxay waddaa 130+ unug sabbeyn ah oo ku yaalla naxaasta, zinc, iyo wareegyada rasaasta - isku darka Denver DR, Metso TankCell, iyo moodooyinka Outotec oo loo wakiishay wejiyo ballaarin oo kala duwan. Dalabka wax-soo-saarka badan ee daboolaya hal calaamad oo keliya ayaa ku qasbaya kooxda wax soo iibsiga inay maamulaan 3-4 alaab-qeybiyeyaal kala duwan. Hawlgallada lagu soo saarayo sabbeynta qaybo ka mid ah naxaasta macdanta sare ee Peru waxay xidhataa qaybo, iskudhisyada caqabada ah: samaynta dabacsanaanta qabow ee sare waa dhif in laga helo alaab-qeybiyeyaasha oo dhan isku mar. Natiijada: 3x Amarka Iibka, 3x fasaxa kastamka, 3x kormeerka helitaanka.
Sida aan u xalinno:
Dalabka badan ee dhammaan noocyada kala duwan - Denver DR, Metso OK, IYO Outotec FloatForce hal PO, hal weel, hal kharash oo dhulka ah
Qiimaha badan ee laga bilaabo 12 qaybood - maaha nooc kasta. Isku qas oo ku dheji DR-24 impellers oo leh OK-100 rotors; dhimista tirada ayaa khuseysa wadarta guud
Bakhaarka isku dhafka Callao - waxaanu diyaarinaa dalabkaaga badan ee soo qaadida ama geyn DDP albaabka miinada; doorashadaada
2. Heer-dhexe & Hawlgallada Rasmiga ah ee Farshaxanka (Buenaventura, Volcan, Hochschild)
Cidda ay khusayso: Maamulayaasha dhirta ee 5,000-15,000 tpd hawlgallada halkaas oo soo iibsiga uu sameeyo kormeeraha dayactirka, ma aha waaxda silsilad sahayda u go'an.
Dhibaatada: Hawlgalladani waxay wadaan qalabka Denver - qaar ka mid ah unugyada DR-24 ayaa jira 25+ sano - OEM-na si firfircoon uma taageerto moodelka. Qalabaynta beddelka ayaa laga keenay wax kasta oo qaybiyaha ahi kaydka leeyahay, badiyaa 40-60% ka sarreeya qiimaha bulk sababtoo ah tirada dalabku waa 2-4 marba. Waxaa ka sii daran, qaar ka mid ah alaab-qeybiyeyaasha qaarkood waxay soo raraan qalabyada "taam caalami ah" oo u baahan shimmeynta goobta iyo shiidi si ay ugu habboonaato - ku dar 4-6 saacadood oo shaqo dayactir ah rakibid kasta.
Sida aan u xalinno:
Mashiinka CNC-ga gaarka ah ee moodeelka - impeller kasta waxaa lagu farsameeyay OEM DR/ cabbir-A cabbirka xuddunta. Ma jiro shimming, ma shiidi, maya "isku hagaaji si ku habboon"
Soo dhaweyn-dalbasho yar, qiimaha badan oo la sharfay - dalbo 2 qaybood ama 20; Qiimahaaga halbeeg-kiiba isma beddelo
Hagaha rakibaadda luuqada Isbaanishka oo leh tafaasiisha torque-ga, habka cabbiraadda farqiga, iyo jadwal jeeg xidhasho - oo loo qoray makaanigga, ma aha injineerka
Xalka xidhashada xoogga saaraya oo dhammaystiran: Baadhitaanka Shaashadda caagga ah ee kala duwan waxay gacanta ku haysaa SAG iyo dheecaanka-shiidka ka hor sabbeynta. Ku xidh Tuubbada Macdanta ee kala wareejinta dareeraha ee u dhexeeya taangiyada qaboojiyaha iyo unugyada ugu horreeya ee qallafsan.
Daraasadda Kiis: Toromocho - Qabow-Cimilada Impeller Waxqabadka
Asalkii hore
Marka Minera Chinalco Perú's Toromocho hawlgalka (gobolka Junín, 4,600m sare u kaca, 117,200 tpd copper-molybdenum ore) soo saaray RFQ ah sabbaynaya impeller diffuser Peru bulk sahayda, shuruudaha qiimaynta waxaa u badnaa hal metric: badbaadada-bilowga qabow. Xaruntu waxay waddaa 48 unugyada Denver DR-30 ee bangiga qallafsan. Heerkulka deegaanka jiilaalka wuxuu caadi ahaan gaaraa -10 ° C; heerkulka slurry ee meesha qaboojiyaha celcelis ahaan 8°C bilaha 6aad-Agoosto.
Caqabadda
Caadiga ah polyurethane DR-30 impellers: 7% heerka dilaaca qabow-bilawga (OEM + alaab-qeybiyeyaasha guud, xogta 2022-2023)
Celceliska nolosha adeegga impeller: 11.3 bilood
Guul-darrooyinka la xidhiidha qabowgu waxa ay uruursadeen bilaha 6aad-Agoosto, oo ku beegan inta ugu badan ee wax-soo-saarka xog-ururinta
Beddelka Impeller wuxuu u baahan yahay saacadaha 4.5 ee hoos u dhaca unugga - oo ah 117,200 tpd, taasi waa 22,000 tan oo macdan ah oo dhaafinaysa sabbeynta dhacdo kasta
Xalkayaga
Waxaa la geeyay 32 RIOLATEX qabow-flex polyurethane Denver DR-30 impellers oo dhan 16 unug qallafsan (Bank A, unugyada 1-16) Janaayo 2024. Isbarbardhigga la xakameeyey ee ka dhanka ah 32 impellers polyurethane caadiga ah ee Bank B (unugyada 17-32) in ka badan wareegga jiilaalka buuxa (Jun-44Aug)

FAQ
S: Denver-kaaga ku habboon matoorka dabaylaha flotation polyurethane - sidee buu habowga qabowgu uga duwan yahay poliurethane caadiga ah?
A: Polyurethane caadiga ah waxay isticmaashaa MDI (diphenylmethane diisocyanate) oo leh laf dhabarta polyeter-ka. Marka heerkulku hoos uga dhaco 0°C, qaybaha adag waxay lumiyaan dhaq-dhaqaaqa, taasoo keenaysa in walxuhu adkaadaan - adkaanta xeebta waxay kor uga kacdaa 90A ilaa 96-98A, dhererkeeduna wuxuu hoos uga dhacayaa 450% ilaa 200-250%. Qaabayntayada qabow-jilicsan waxay beddeshay 30% polyeter-ka polyol-ka leh koobiyeerka polyester-polyeter kaas oo leh heerkulka kala-guurka galaas (Tg) ee -35°C halkii uu ka ahaan lahaa -15°C. Natiijadu: Shore 90A at 20°C waxay noqotaa 92A at -10°C halkii ay ka ahaan lahayd 97A, dhererkeeduna waxa uu ka sarreeyaa 480%. Iska caabin nabar isku mid ah, dabacsanaan qabow oo aad u fiican. Waxaan kuu soo diri doonaa qalooca DMA xigashadaada.
S: Ma keeni kartaa Denver Sub-A impellers? Kuwaas waxaa ku adkaanaya in la helo.
J: Haa — Denver Sub-A 18, 21, 24, 30, iyo 48. Wali waanu soo saarnay kuwan sababtoo ah hawlgallada Peruvian (gaar ahaan wareegyada zinc-lead polymetallic) waxay sii wadaan inay socdaan. Sub-A impeller waxa uu leeyahay taper hub kala duwan iyo daab tirinta vs. Taxanaha DR - hubi inaad cadd "Denver Sub-A" iyo size unugga, ma aha oo kaliya "Denver impeller." Waxaan xaqiijin doonaa cabbirka xuddunta ee ka soo horjeeda usheeda hore ka hor intaanad shubin.
