Ho fihlela ka Hlakola 2020, setsi sa polokelo ea oli boema-kepeng ba Brazil se ne se sebelisa lipompo tse peli tsa centrifugal ho tsamaisa oli e boima ho tloha litankeng tsa polokelo ho ea ho literaka tsa litanka kapa likepe. Sena se hloka ente ea mafura a diesel ho fokotsa viscosity e phahameng ea seaplane, e theko e boima. Beng ba bona ba fumana bonyane $2,000 ka letsatsi. Ho phaella moo, lipompo tsa centrifugal hangata li hlōleha ka lebaka la tšenyo ea cavitation. Mong'a ntlo o ile a etsa qeto ea ho fetola e 'ngoe ea lipompo tse peli tsa centrifugal sebaka ka pompo ea NOTOS® multiscrew e tsoang NETZSCH. Ka lebaka la bokhoni ba eona bo botle ba ho hula, pompo e khethiloeng ea 4NS ea li-screw tse 'nè e boetse e loketse mecha ea litaba e phahameng ea viscosity ho fihlela ho 200,000 cSt, e fana ka litekanyetso tsa ho phalla ho fihla ho 3000 m3 / h. Ka mor'a ho laela, ho ile ha hlaka hore pompo ea li-multiscrew e ka sebetsa ntle le cavitation esita le ka litekanyetso tse phahameng haholo tsa phallo ha li bapisoa le lipompo tse ling tsa centrifugal. Molemo o mong ke hore ha ho sa hlokahala ho eketsa mafura a diesel ka bongata. Ho itšetlehile ka phihlelo ena e ntle, ka February 2020 moreki o ile a boela a etsa qeto ea ho nkela pompo ea bobeli ea centrifugal sebaka ka NOTOS ® . Ho phaella moo, ho hlakile hore tšebeliso ea matla e ka fokotsoa haholo.
"Lipompo tsena li sebelisetsoa ho tsamaisa oli e boima ho tloha mapolasing a litanka ho ea ho literaka tsa litanka kapa likepe boema-kepeng ba leboea-bochabela ho Brazil, haholo-holo nakong ea komello," ho hlalosa Vitor Assmann, Mookameli e Moholo oa Thekiso NETZSCH Brazil. "Sena ke hobane lifeme tsa naha tse fehlang motlakase ka metsi li hlahisa matla a fokolang ka linako tsena, e leng se eketsang tlhokahalo ea oli e boima. Ho fihlela ka February 2020, phetisetso ena e ne e etsoa ho sebelisoa lipompo tse peli tsa centrifugal, leha ho le joalo pompo ena ea centrifugal e ne e loantšana le viscosity e phahameng." tikoloho. Vitor Assmann oa hlalosa: “Lipompo tse tloaelehileng tsa centrifugal li na le matla a fokolang a ho monya, ho bolelang hore oli e ’ngoe e sala ka letamong ’me ha e khone ho sebelisoa. "Ho phaella moo, theknoloji e fosahetseng e ka lebisa ho cavitation, e leng se tla lebisa ho hlōleha ha pompo ka nako e telele."
Lipompompo tse peli tsa centrifugal polasing ea litanka tsa Brazil le tsona li na le bothata ba cavitation. Ka lebaka la viscosity e phahameng, boleng ba NPSHa ba tsamaiso bo tlaase, haholo-holo bosiu, e leng se lebisang ho tlhokahalo ea ho eketsa mafura a dizeli a theko e boima ho oli e boima ho fokotsa viscosity. Asman o ile a tsoela pele ho re: “Ho hlokahala hore ho eketsoe lilithara tse ka bang 3 000 letsatsi le leng le le leng, e leng se bitsang bonyane $2 000 ka letsatsi. E le ho ntlafatsa ts'epo ea ts'ebetso le ts'ebetso le ho fokotsa litšenyehelo tsa matla, mong'a lona o ile a etsa qeto ea ho nkela sebaka se seng sa lipompo tse peli tsa centrifugal ka NOTOS ® multiscrew pump ho tloha NETZSCH le ho bapisa ts'ebetso ea lihlopha tse peli.
Mofuta oa NOTOS ® o atisa ho kenyelletsa lipompo tse ngata tse nang le li-screw tse peli (2NS), tse tharo (3NS) kapa tse 'nè (4NS), tse ka sebelisoang habonolo ho sebetsana le li-viscosity tse fapaneng esita le litekanyetso tse phahameng tsa phallo. Setsi sa oli sa Brazil se ne se hloka pompo e khonang ho pompa ho fihla ho 200 m3/h ea oli e boima ka khatello ea 18 bar, mocheso oa 10-50 ° C le viscosity e fihlang ho 9000 cSt. Mong'a polasi ea tanka o ile a khetha 4NS twin screw pump, e nang le bokhoni ba ho fihla ho 3000 m3 / h 'me e loketse mecha ea litaba ea viscous e fihlang ho 200,000 cSt.
Pompo e ka tšeptjoa haholo, e khona ho mamella matha a omileng 'me e ka etsoa ka thepa e khethiloeng ka ho khetheha bakeng sa kopo. Theknoloji ea morao-rao ea tlhahiso e lumella ho mamellana ho matla pakeng tsa likarolo tse matla le tse tsitsitseng, ka hona ho fokotsa tlhokahalo ea ho phalla hape. Ho kopantsoe le sebopeho sa kamore ea pompo e ntlafalitsoeng ea phallo, katleho e phahameng e finyelloa.
Leha ho le joalo, ntle le ts'ebetso e nepahetseng, ho feto-fetoha ha pompo ho latela viscosity ea pompong ea pompo ke ea bohlokoa ka ho khetheha ho beng ba mapolasi a tanka ea Brazilian: "Le hoja mefuta e mengata ea ts'ebetso ea lipompo tsa centrifugal e le moqotetsane 'me ha viscosity e ntse e eketseha, bokhoni ba bona bo fokotseha haholo. The NOTOS® pompo ea li-screw tse ngata e sebetsa ka mokhoa o atlehileng haholo ho pholletsa le mefuta eohle ea li-Viscosity Manager. "Mohopolo ona oa ho pompa o itšetlehile ka ho sebelisana pakeng tsa auger le matlo.

Sekhahla sa phallo se angoa ke lebelo la pompo, bophara le bophahamo ba pompo. Ka lebaka leo, e lekana ka kotloloho le lebelo mme e ka lokisoa hantle ka eona.
Lipompompo tsena li ka ikamahanya le ts'ebeliso ea hajoale ho fihlela ts'ebetso e nepahetseng. Sena se ameha haholo-holo litekanyo tsa pompo le mamello ea eona, hammoho le lisebelisoa.

"Bakeng sa kopo ea Brazil, viscosity ea mecha ea phatlalatso e kopantsoeng le lebelo la pompo e ne e hloka tiiso e habeli e nang le mokhoa oa ho tiisa ka ntle," ho hlalosa Vitor Assmann. Ka kopo ea moreki, moralo o lumellana le litlhoko tsa API.
Hobane 4NS e khona ho sebetsa libakeng tse nang le viscosity e phahameng, ha ho hlokahale ho kenya mafura a diesel. Sena se ile sa fokotsa litšenyehelo ka $2,000 ka letsatsi.
