Ilaa Febraayo 2020, bakhaarka kaydka saliida ee dekeda Brazil wuxuu isticmaalay laba bambooyin centrifugal ah si uu saliidda culus uga soo qaado haamaha kaydinta una geeyo booyadaha ama maraakiibta. Tani waxay u baahan tahay duritaanka shidaalka naaftada si loo yareeyo viscosity sare ee dhexdhexaadka ah, taas oo ah qaali. Milkiilayaasha waxay helaan ugu yaraan $2,000 maalintii. Intaa waxaa dheer, bambooyin centrifugal ah ayaa badanaa ku guuldareysta sababtoo ah burburka cavitation. Mulkiiluhu wuxuu go'aansaday inuu marka hore ku beddelo mid ka mid ah labada bambooyin centrifugal ah NOTOS® bamka isku xidhka badan ee NETZSCH. Waad ku mahadsan tahay awooddeeda nuugista ee aadka u wanaagsan, bamka 4NS ee la doortay ee afarta ah ayaa sidoo kale ku habboon warbaahinta viscosity-sare ilaa 200,000 cSt, taasoo gaarsiinaysa heerka socodka ilaa 3000 m3 / h. Ka dib markii la hawlgeliyay, waxaa caddaatay in bamka isku-xidhka badan uu shaqayn karo iyada oo aan daloolin xitaa heerka socodka qulqulka oo aad u sarreeya marka loo eego matoorada kale ee centrifugal. Faa'iidada kale ayaa ah in aan loo baahnayn in lagu daro tiro badan oo shidaal naafto ah. Iyada oo ku saleysan waayo-aragnimadan togan, Febraayo 2020 macmiilku wuxuu kaloo go'aansaday inuu ku beddelo bamka centrifugal labaad NOTOS ® . Intaa waxaa dheer, way caddahay in isticmaalka tamarta si weyn loo dhimi karo.
"Bambooyinkan waxaa loo isticmaalaa in lagu qaado saliidda culus ee laga keeno taangiyada laguna geeyo gawaarida booyadaha ama maraakiibta ku sugan dekedaha waqooyi bari Brazil, inta badan xilliyada abaarta," ayuu yiri Vitor Assmann, Maamulaha Iibka Sare ee NETZSCH Brazil. "Tani waa sababta oo ah warshadaha korontada ee dalka ayaa soo saara tamar yar xilliyadan, taas oo kordhinaysa baahida saliidda culus. Ilaa Febraayo 2020, wareejintan waxaa lagu fuliyay laba bambooyin centrifugal ah, si kastaba ha ahaatee bamka centrifugal wuxuu la halgamay viscosity sare." deegaanka. "Matoorada centrifugal ee caadiga ah waxay leeyihiin awood nuugista oo liidata, taas oo macnaheedu yahay in saliidda qaar ay ku hadhsan tahay kaydka oo aan la isticmaali karin," ayuu yidhi Vitor Assmann. "Intaa waxaa dheer, tignoolajiyada khaldan waxay keeni kartaa cavitation, taas oo u horseedi doonta bamka fashilka mustaqbalka fog."
Laba bambooyin centrifugal ah oo ku yaal beer taangiyada Brazil ayaa sidoo kale la ildaran cavitation. Sababtoo ah viscosity sare, qiimaha NPSHa ee nidaamku waa mid hooseeya, gaar ahaan habeenkii, taas oo horseedaysa baahida loo qabo in lagu daro shidaal naafto ah oo qaali ah saliid culus si loo yareeyo viscosity. "Ilaa 3,000 oo litir ayaa loo baahan yahay in lagu daro maalin kasta, taasoo qiimaheedu yahay ugu yaraan $2,000 maalintii," ayuu Asman sii waday. Si loo hagaajiyo isku halaynta iyo hufnaanta nidaamka loona yareeyo kharashaadka tamarta, mulkiiluhu wuxuu go'aansaday inuu ku beddelo mid ka mid ah labada bambooyin centrifugal ah NOTOS ® bamka isku-xidhka badan ee NETZSCH oo barbar dhigo waxqabadka labada cutub.
Kala duwanaanshaha NOTOS ® caadi ahaan waxaa ku jira bambooyin isku dhafan oo leh laba (2NS), saddex (3NS) ama afar (4NS), kuwaas oo si dabacsan loogu isticmaali karo in lagu xakameeyo viscosities kala duwan iyo xitaa heerarka socodka sare. Kaydka saliidda ee Brazil wuxuu u baahday bam awood u leh inuu soo saaro ilaa 200 m3/h saliid culus oo cadaadis ah 18 bar, heerkul ah 10-50 °C iyo viscosity ilaa 9000 cSt. Mulkiilaha beerta taangiga ayaa doortay bamka isku xidhka mataanaha ah ee 4NS, kaas oo leh awood ilaa 3000 m3/h kuna haboon warbaahinta aadka u liidata ilaa 200,000 cSt.
Bamka waa mid aad loo isku halleyn karo, wuxuu u adkeysan karaa orodka qalalan waxaana laga soo saari karaa alaabta si gaar ah loogu doortay codsiga. Tiknoolajiyada casriga ah ee wax soo saarka ayaa u oggolaanaya dulqaad adag oo u dhexeeya qaybaha firfircoon iyo kuwa taagan, taas oo yaraynaysa baahida dib u soo noqoshada. Marka lagu daro qaabka qolka bamka ee socodka-ku-habboon, waxtarka sare ayaa la gaaraa.
Si kastaba ha ahaatee, marka lagu daro waxtarka, dabacsanaanta ee bamka marka la eego viscosity ee dhexdhexaadka ah bamgareynta ayaa si gaar ah muhiim u ah milkiilayaasha beeraha taangiyada Brazil: "In kasta oo kala duwan ee hawlgalka ee bambooyin centrifugal waa cidhiidhi iyo sida viscosity korodho, ay hufnaan si aad u yaraynaysaa. "Fikraddan bamgareynta waxay ku salaysan tahay isdhexgalka ka dhexeeya auger iyo guriyeynta. Waxay samaysaa qol gaadiid ah kaas oo dhexdhexaadku si joogto ah uga socdo dhinaca gudaha ilaa dhinaca dheecaanka ee cadaadiska xasilloon - ku dhawaad iyada oo aan loo eegin joogteynta ama viscosity ee dhexdhexaadka." Heerka socodka waxa saameeya xawaraha bamka, dhexroorka iyo garoonka auger-ka. Sidaa awgeed, waxay si toos ah ula siman tahay xawaaraha oo si habsami leh ayaa loo hagaajin karaa iyada oo loo marayo.
Bambooyinkan waxaa lagu hagaajin karaa codsiga hadda jira si loo gaaro waxqabadka ugu fiican. Tani waxay khusaysaa inta badan cabbirka bamka iyo dulqaadkiisa, iyo sidoo kale qalabyada. Tusaale ahaan, alwaaxyada cadaadiska xad-dhaafka ah, nidaamyada kala duwan ee xidhidhiyaha iyo qalabka la socodka isticmaalka heerkulka iyo dareemayaasha gariirku waa la isticmaali karaa. "Codsiga Brazil, viscosity ee warbaahinta oo ay weheliso xawaaraha bamka ayaa loo baahan yahay shaabad labanlaab leh oo leh nidaam dibadda ah," ayuu yiri Vitor Assmann. Codsiga macmiilka, naqshaddu waxay u hoggaansamaysaa shuruudaha API.
Sababtoo ah 4NS waxay ku shaqayn kartaa deegaan aad u badan, looma baahna in lagu duro shidaalka naaftada. Tani, dhankeeda, waxay hoos u dhigtay kharashaadka $2,000 maalintii. Intaa waxaa dheer, bamka wuxuu u shaqeeyaa si hufan marka uu bamgareynayo warbaahinta viscous sida, hoos u dhigista isticmaalka tamarta in ka badan 40% ilaa 65 kW. Tani waxay badbaadinaysaa xitaa kharashyo tamar oo badan, gaar ahaan ka dib marxaladda tijaabada ah ee guusha leh ee Febraayo 2020, bamka centrifugal labaad ee jira ayaa sidoo kale lagu beddelay 4NS.
