Kuze kube nguFebhuwari 2020, idepho kawoyela esikhumulweni semikhumbi sase-Brazil yayisebenzisa amaphampu amabili amaphakathi ukuthutha uwoyela osindayo usuka emathangini okugcina uya emalolini angamathangi noma imikhumbi. Lokhu kudinga ukujova udizili ukuze kwehliswe i-viscosity ephezulu ye-medium, ebiza kakhulu. Abanikazi bahola okungenani u-$2,000 ngosuku. Ngaphezu kwalokho, amaphampu e-centrifugal ngokuvamile ahluleka ngenxa yokulimala kwe-cavitation. Umnikazi unqume ukuthi aqale ashintshe enye yamaphampu amaphakathi amabili esikhundleni sephampu eyi-NOTOS® multiscrew pump evela kwa-NETZSCH. Ngenxa yomthamo wayo omuhle kakhulu wokudonsa, iphampu ye-4NS yesikulufu esine ekhethiwe nayo ifanele imidiya ye-viscosity ephezulu efika ku-200,000 cSt, iletha amazinga okugeleza afika ku-3000 m3/h. Ngemuva kokugunyazwa, kwacaca ukuthi ipompo ye-multiscrew ingasebenza ngaphandle kwe-cavitation ngisho namazinga okugeleza aphezulu kakhulu uma kuqhathaniswa namanye amaphampu we-centrifugal. Enye inzuzo ukuthi akusadingeki ukufaka inqwaba kaphethiloli kadizili. Ngokusekelwe kulokhu okuhlangenwe nakho okuhle, ngoFebruwari 2020 ikhasimende liphinde lanquma ukushintsha iphampu yesibili eyi-centrifugal nge-NOTOS ® . Ngaphezu kwalokho, kusobala ukuthi ukusetshenziswa kwamandla kungancishiswa kakhulu.
“Lawa maphampu asetshenziselwa ukuthutha uwoyela osindayo usuka emapulazini amathangi ukuya emalolini angamathangi noma imikhumbi emachwebeni asenyakatho-mpumalanga yeBrazil, ikakhulukazi ngezikhathi zesomiso,” kuchaza uVitor Assmann, uMphathi Omkhulu Wokuthengisa kwa-NETZSCH Brazil. "Lokhu kungenxa yokuthi izimboni zamandla kagesi eziphehla ugesi ezweni zikhiqiza amandla amancane ngalezi zikhathi, okwandisa isidingo sikawoyela omkhulu. Kuze kube nguFebhuwari 2020, lokhu kudluliselwa kwenziwa kusetshenziswa amaphampu amabili angama-centrifugal, kodwa le futha ye-centrifugal ibinenkinga yokubonakala okuphezulu." imvelo. “Amaphampu avamile ayi-centrifugal awakwazi kahle ukumunca, okusho ukuthi uwoyela othile usala echibini futhi awukwazi ukusetshenziswa,” kuchaza uVitor Assmann. "Ngaphezu kwalokho, ubuchwepheshe obungalungile bungaholela ku-cavitation, okuzoholela ekuhlulekeni kwepompo ngokuhamba kwesikhathi."
Amaphampu amabili angama-centrifugal epulazini lamathangi aseBrazil nawo ahlushwa yi-cavitation. Ngenxa ye-viscosity ephezulu, inani le-NPSHa lesistimu liphansi, ikakhulukazi ebusuku, okuholela esidingweni sokwengeza uphethiloli we-diesel obizayo emafutheni asindayo ukuze kuncishiswe i-viscosity. “Cishe amalitha angu-3 000 adinga ukwengezwa nsuku zonke, okubiza okungenani u-$2,000 ngosuku,” kuqhubeka u-Asman. Ukuze kuthuthukiswe ukuthembeka kwenqubo nokusebenza kahle nokunciphisa izindleko zamandla, umnikazi wanquma ukushintsha enye yamaphampu amabili e-centrifugal nge-NOTOS ® multiscrew pump evela ku-NETZSCH futhi aqhathanise ukusebenza kwamayunithi amabili.
Ububanzi be-NOTOS ® ngokuvamile buhlanganisa amaphampu we-multiscrew anezikulufu ezimbili (2NS), ezintathu (3NS) noma ezine (4NS), ezingasetshenziswa kalula ukuphatha ama-viscosity ahlukene ngisho namazinga aphezulu okugeleza. Idepho kawoyela eBrazil yayidinga iphampu ekwazi ukumpompa uwoyela osindayo ofika ku-200 m3/h ngokucindezela okungu-18 bar, izinga lokushisa elingu-10–50 °C kanye ne-viscosity efika ku-9000 cSt. Umnikazi wepulazi lethangi ukhethe i-4NS twin screw fumpu, enamandla angafika ku-3000 m3/h futhi ifanele imidiya ebonakalayo efika ku-200,000 cSt.
Iphampu inokwethenjelwa kakhulu, ingakwazi ukumelana nokusebenza okomile futhi ingakhiqizwa ngezinto ezikhethelwe uhlelo lokusebenza. Ubuchwepheshe besimanje bokukhiqiza buvumela ukubekezelelana okuqinile phakathi kwezingxenye eziguqukayo nezimile, ngaleyo ndlela kunciphisa isidingo sokugeleza kabusha. Ngokuhambisana nokugeleza kwegumbi lepompo elilungiselelwe ukugeleza, ukusebenza kahle okuphezulu kufinyelelwa.
Kodwa-ke, ngaphezu kokusebenza kahle, ukuguquguquka kwepompo ngokuya nge-viscosity yendawo yokumpompa kubaluleke kakhulu kubanikazi bamapulazi amathangi ase-Brazilian: "Ngenkathi uhla lokusebenza lwamaphampu amaphakathi luncane futhi njengoba i-viscosity ikhula, ukusebenza kahle kwawo kuncipha kakhulu. Ipompo ye-NOTOS ® enezikulufu eziningi isebenza kahle kakhulu kulo lonke uhla lwe-viscosity Senior Manager. "Lo mqondo wokumpompa usekelwe ekusebenzelaneni phakathi kwe-auger nezindlu. Wakha igumbi lokuthutha lapho okuphakathi kuhamba ngokuqhubekayo ukusuka ohlangothini lokungena kuya ohlangothini lokukhipha ngaphansi kwengcindezi ezinzile - cishe kungakhathaliseki ukuvumelana noma ukubukeka kwe-medium." Izinga lokugeleza lithintwa isivinini sepompo, ububanzi kanye nokuphakama kwe-auger. Ngenxa yalokho, ilingana ngokuqondile nesivinini futhi ingalungiswa kahle ngayo.
Lawa maphampu angashintshwa ukuze asetshenziswe manje ukuze afeze ukusebenza kahle. Lokhu kuthinta ikakhulukazi ubukhulu bepompo kanye nokubekezelela kwayo, kanye nezinsiza. Isibonelo, ama-valve okucindezela ngokweqile, izinhlelo ezihlukahlukene zokuvala kanye namadivayisi okuqapha okuthwala asebenzisa izinzwa zokushisa nokudlidliza angasetshenziswa. "Ngohlelo lokusebenza lwaseBrazil, i-viscosity yabezindaba ehlangene nesivinini sepompo idinga uphawu oluphindwe kabili ngesistimu yokuvala yangaphandle," kuchaza uVitor Assmann. Ngokwesicelo seklayenti, umklamo uhambisana nezidingo ze-API.
Ngenxa yokuthi i-4NS ingasebenza ezindaweni ezine-viscosity ephezulu, asikho isidingo sokujova uphethiloli wedizili. Lokhu, kwehlisa izindleko ngo-$2,000 ngosuku. Ngaphezu kwalokho, ipompo isebenza ngokuphumelelayo lapho idonsa imidiya enjalo ye-viscous, inciphisa ukusetshenziswa kwamandla ngaphezu kuka-40% kuya ku-65 kW. Lokhu konga izindleko zamandla ezengeziwe, ikakhulukazi ngemva kwesigaba sokuhlola esiyimpumelelo ngoFebhuwari 2020, iphampu yesibili ekhona ye-centrifugal nayo yathathelwa indawo yi-4NS.
