Ho lahleheloa ke molumo le ho thibela tahlehelo ea pompo ea slurry
Ho lahleheloa ke molumo centrifugal china slurry pump seal ring leakage loss , tahlehelo ea ho leka-lekana pakeng tsa mekhatlo le boemo ba tahlehelo ea ho lutla.
Tahlehelo ea ho lutla ha selikalikoe sa tiiso
Ka hare ho impeller inlet, lesale la ho tiisa mosebetsing oa pompo ea slurry ea china, hobane mehele ea ho tiisa ka mahlakoreng ka bobeli ho na le phapang ea khatello, lehlakoreng la khatello ea motlakase e ka bang lehlakoreng le leng la khatello ea ho kenya letsoho, kahoo ho tla lula ho le teng. karolo ea mokelikeli ho tloha moemelong ho ea ho ho dutla ho hoholo.Karolo ena ea mokelikeli o fumanoang ka matla a impeller , empa mokelikeli ha o rometsoe, kahoo o fokotsa palo ea metsi a china slurry pump .Matla ohle a sebelisitsoeng ho hlola ho lutla ha selikalikoe sa tiiso ea mokelikeli ho khanyetso .
Ho hlakile hore bophara ba reng ea tiiso e kholoanyane Dw, ho futsaneha ho feta mahlakoreng ka bobeli a phapang ea khatello, ho na le palo e kholo ea ho lutla.Bakeng sa stereotypes lipompo tsa slurry tsa china, e le ho fokotsa palo ea ho lutla ho ntlafatsa ts'ebetso ea pompo ea slurry ea china e lokela ho lumelloa tabeng ea ho fokotsa lekhalo la lesale la tiiso.Ka kakaretso e hakanyetsoang ho kakaretso ea tiiso ea tiiso bophara ba 0.002, joalo ka Dw = 200 mm, tumello eohle ea 0.40 mm .Ha e bokelloa, selikalikoe sa tiiso ha se seholo haholo, ho seng joalo, palo ea ho lutla e tla eketseha.Mehato e 'ngoe ea bohlokoa e sebelisetsoang ho eketsa ho hanyetsa mokhoa oa lesale la tiiso bakeng sa ho fokotsa palo ea ho lutla, ho eketsa ho hanyetsa ha lesale la tiiso ho etsoa ??ea maze, zigzag, joalo-joalo E boetse e eketsa bolelele ba lesale la tiiso, ho eketsa khanyetso tseleng .

Ea bobeli, tahlehelo ea ho lutla ha mokhoa oa ho leka-lekana
Ho tse ngata tsa centrifugal china slurry pump , axial thrust balancing feature institution : tse kang likoti tse leka-lekaneng, ho laola ho leka-lekana, ho leka-lekana disc.Kaha ho na le mahlakore a mabeli a ho leka-lekanya mochine o fapaneng oa khatello , 'me kahoo karolo ea ho tsoa ha metsi ho tloha sebakeng sa khatello e phahameng ho ea sebakeng sa khatello e tlaase.Hoo e ka bang 5% ho fokotsa lesoba la ho lutla ho ka leka-lekanya katleho ea pompo ea slurry ea china.Litsing tsa li-disc tsa ho leka-lekana, litlaleho tsa leakage bakeng sa 3% ea phallo ea mosebetsi, empa tse ling tsa pompo ea slurry ea china e phahameng ea khatello e kholo ho feta ena;e le ho fokotsa tahlehelo ea ho lutla ho ka fokotsoa ho leka-lekana disc bophara ba D ntle le ho ama boemo ba counterweight '.
Ea boraro, tahlehelo ea ho lutla ha li-interstage
Ka har'a pompo ea slurry ea China e nang le mekhahlelo e mengata, sebaka sa sebaka ka mahlakoreng ka bobeli a likhahla tsa khatello, kahoo ho na le tahlehelo ea ho lutla, ho ea ka tlhophiso ea mekhatlo e fapaneng, boemo ba khatello mahlakoreng ka bobeli a lipoleiti tsa spacer e ka ba tsa mantlha, secondary kapa tertiary , mekhahlelo e mengata e fapana, joale ho na le ho lutla ho matla ho feta pakeng tsa boemo ba karohano, ka hona mona ho sebelisoa haholo har'a tiiso ea mohato oa mohato.
