Ukuza kuthi ga ngoFebruwari 2020, indawo yokugcina ioyile kwizibuko laseBrazil isebenzise iimpompo ezimbini ezingundoqo ukuthutha ioyile enkulu ukusuka kwiitanki zokugcina ukuya kwiilori okanye iinqanawa. Oku kufuna inaliti ye-diesel ye-diesel ukunciphisa i-viscosity ephezulu ye-medium, ebiza kakhulu. Abanini barhola ubuncinci i-2,000 yeedola ngosuku. Ukongeza, iimpompo ze-centrifugal zihlala zisilela ngenxa yomonakalo we-cavitation. Umnini wagqiba ekubeni aqale atshintshe enye yeempompo ezimbini ze-centrifugal kunye ne-NOTOS® multiscrew pump evela kwi-NETZSCH. Ngombulelo kumandla ayo okufunxa kakuhle kakhulu, i-4NS ekhethiweyo yempompo ye-screw yesine ikwafanelekile kwimidiya ye-viscosity ephezulu ukuya kwi-200,000 cSt, ihambisa amazinga okuhamba ukuya kwi-3000 m3 / h. Emva kokugunyaziswa, kwacaca ukuba ipompo ye-multiscrew ingasebenza ngaphandle kwe-cavitation nakwizinga eliphezulu kakhulu lokuhamba xa kuthelekiswa nezinye iimpompo ze-centrifugal. Enye inzuzo kukuba akusekho mfuneko yokongeza umthamo omkhulu wamafutha edizili. Ngokusekelwe kula mava alungileyo, ngoFebruwari 2020 umthengi naye wagqiba ekubeni atshintshe impompo yesibini ye-centrifugal nge-NOTOS ®. Ukongezelela, kucacile ukuba ukusetyenziswa kwamandla kunokunciphisa kakhulu.
“Ezi mpompo zisetyenziselwa ukuthutha i-oyile enzima ukusuka kwiifama zetanki ukuya kwiilori ezithwala inqwelo-mafutha okanye iinqanawa kumazibuko aseMntla-mpuma weBrazil, ingakumbi ngamaxesha embalela,” ucacise watsho uVitor Assmann, uMphathi oMkhulu weNtengiso kwi-NETZSCH Brazil. Oku kungenxa yokuba amaziko ombane weli lizwe avelisa amandla amancinci ngeli xesha, nto leyo eyandisa imfuno yeoli eninzi. Ukuza kuthi ga ngoFebruwari ka-2020, olu tshintsho lwenziwe kusetyenziswa iimpompo ezimbini ze-centrifugal, nangona kunjalo le mpompo ye-centrifugal inengxaki ye-viscosity ephezulu. okusingqongileyo. "Iipompo ze-centrifugal eziqhelekileyo zinomthamo ophantsi wokufunxa, oku kuthetha ukuba enye ioli ihleli kwindawo yokugcina amanzi kwaye ayikwazi ukusetyenziswa," kuchaza uVitor Assmann. "Ukongezelela, iteknoloji engalunganga ingakhokelela kwi-cavitation, eya kubangela ukungaphumeleli kwempompo kwixesha elide."
Iimpompo ezimbini ze-centrifugal kwifama yetanki yaseBrazil nazo zinengxaki ye-cavitation. Ngenxa ye-viscosity ephezulu, ixabiso le-NPSHa lenkqubo liphantsi, ngakumbi ebusuku, okukhokelela kwisidingo sokongeza i-diesel ebiza kakhulu kwioli enzima ukunciphisa i-viscosity. “Kufuneka kongezwe malunga neelitha ezingama-3 000 yonke imihla, nto leyo exabisa ubuncinane iidola ezingama-2 000 ngosuku,” waqhubeka uAsman. Ukuphucula ukuthembeka kwenkqubo kunye nokusebenza kakuhle kunye nokunciphisa iindleko zamandla, umnini wagqiba ekubeni atshintshe enye yeepompo ezimbini ze-centrifugal kunye ne-NOTOS ® impompo ye-multiscrew evela kwi-NETZSCH kwaye uthelekise ukusebenza kweeyunithi ezimbini.
Uluhlu lwe-NOTOS ® ngokuqhelekileyo lubandakanya iimpompo ze-multiscrew ezine-screws ezimbini (2NS), ezintathu (3NS) okanye ezine (4NS) izikrufu, ezinokuthi zisetyenziswe ngokuguquguqukayo ukuphatha i-viscosities eyahlukeneyo kunye namazinga aphezulu okuhamba. Idepho yeoli eBrazil yayifuna impompo ekwazi ukupompa ukuya kuthi ga kwi-200 m3 / h yeoli enzima kuxinzelelo lwe-18 bar, iqondo lobushushu le-10-50 ° C kunye ne-viscosity ukuya kwi-9000 cSt. Umnini wefama yetanki ukhethe i-4NS twin screw pump, enomthamo wokuya kuthi ga kwi-3000 m3/h kwaye ifanele imidiya ebonakalisayo ukuya kuthi ga kwi-200,000 cSt.
Ipompo inokwethenjelwa kakhulu, inokumelana nokusebenza okomileyo kwaye inokuveliswa kwizinto ezikhethiweyo ngokukhethekileyo kwisicelo. Itekhnoloji yale mihla yokuvelisa ivumela unyamezelo olungqongqo phakathi kwezinto eziguquguqukayo kunye ne-static, ngaloo ndlela kuncitshiswa imfuno yokuqukuqela kwakhona. Ngokudibanisa ne-flow-optimized optimized shape yegumbi, ukusebenza okuphezulu kufezekiswa.
Nangona kunjalo, ukongeza ekusebenzeni kakuhle, ukuguquguquka kwepompo ngokubhekiselele kwi-viscosity ye-pump medium kubaluleke kakhulu kubanikazi beefama zetanki zaseBrazil: "Nangona uluhlu olusebenzayo lweempompo ze-centrifugal luncinci kwaye njengoko i-viscosity ikhula, ukusebenza kwabo kuncipha ngokukhawuleza. I-NOTOS ® impompo ye-screw multi-screw isebenza ngokufanelekileyo kulo lonke uluhlu lwe-Viscosity Manager. "Le ngcamango yokumpompa isekelwe ekusebenzisaneni phakathi kwe-auger kunye nezindlu, yenza igumbi lokuthutha apho i-medium ihamba ngokuqhubekayo ukusuka kwicala lokungena ukuya kwicala lokukhupha phantsi koxinzelelo oluzinzile - phantse kungakhathaliseki ukuhambelana okanye i-viscosity ye-medium." Isantya sokuhamba sichatshazelwa sisantya sempompo, idiameter kunye nepitch ye-auger. Ngenxa yoko, ilingana ngokuthe ngqo kwisantya kwaye inokulungiswa ngokutyibilikayo ngayo.
Ezi mpompo ziyakwazi ukulungelelaniswa kwisicelo sangoku ukufezekisa ukusebenza kakuhle. Oku kuxhalabele ubukhulu becala imilinganiselo yempompo kunye nokunyamezela kwayo, kunye nezixhobo. Ngokomzekelo, iivalve zoxinzelelo olugqithisileyo, iinkqubo ezahlukeneyo zokutywinwa kunye nezixhobo zokubeka iliso usebenzisa iqondo lokushisa kunye ne-vibration sensors zingasetyenziswa. "Kwisicelo saseBrazil, i-viscosity yeendaba edibeneyo kunye nesantya sempompo yayifuna ukutywinwa kabini kunye nenkqubo yokutywinwa kwangaphandle," kuchaza uVitor Assmann. Ngesicelo somthengi, uyilo luhambelana neemfuno ze-API.
Ngenxa yokuba i-4NS inokusebenza kwiindawo ezine-viscosity ephezulu, akukho mfuneko yokutofa i-diesel fuel. Oku, kwanciphisa iindleko nge-$ 2,000 ngosuku. Ukongezelela, umpompo usebenza ngokufanelekileyo xa upompa imidiya enjalo ye-viscous, ukunciphisa ukusetyenziswa kwamandla ngaphezu kwe-40% ukuya kwi-65 kW. Oku konga nangakumbi iindleko zamandla, ngakumbi emva kwesigaba sovavanyo esiyimpumelelo ngoFebruwari 2020, impompo yesibini ekhoyo ye-centrifugal nayo yatshintshwa nge-4NS.
