Izinto ezi-1: i-slurry pump impeller kanye ne-volute, njengezinto ezinwebekayo ezifana nerabha, i-neoprene, i-polyurethane resin, evame ukusetshenziswa ngesikhathi sokuphuma kwe-impeller velocity ingaphansi kuka-23 m / s, engathuthukisa ipompo ye-NPSH ngempumelelo.
Izinhlayiya ezi-2 eziqinile emthonyeni wephampu eyi-centrifugal, ukugeleza kwephampu enodaka - ijika lokuphakamisa liphansi uma kuqhathaniswa, futhi ukulahlekelwa ukumelana nokugeleza kwepayipi kuzokhula ngokwanda kwethrafikhi kanye nokunensa, ijika lesici sepayipi kanye ne-Engeli yokusebenza incane, inhloko yezinguquko ezincane ingabangela ukugeleza ukushintsha kakhulu.
3 idizayini yemishini, i-shaft, i-bearing, i-seal, i-pump body, njll.) : i-shaft ne-bearing kumele ibe namandla aphezulu nokuqina nokuthembeka. I-trapezoidal screw connection impeller ngokuvamile ingakwazi ukumelana nomthwalo osindayo, ngaphansi kwesimo somthwalo osindayo kusetshenziswa i-sliding thrust bearing kanye nebhola elithwalayo lisetshenziswa ngokujwayelekile ezimeni zomthwalo omncane.
I-4 ukuguga nokusebenza kwe-hydraulic kwenkinga: ukuze kuncishiswe ukuguga nokukhala, kufanele kugcinwe izingxenye ezijikelezayo futhi isivinini samanzi siphansi ngokwanele, uhlaka lwe-alloy oluqinile lwepompo lomzimba noma ugqinsi lwe-elastic lubrication lubrication cross section kufanele lunyuswe, ukuze kuhlangatshezwane nezidingo. yokusebenza okungokoqobo. Kuphrofayili ye-radial ye-impeller, ngokuvamile eseduze nonxande, futhi ayemancane endizeni eqondile kusetshenziswa indawo yokuzungezisa uphawu lwe-axial yangaphambili, umklamo ovamile we-pump casing ye-half spiral, noma eyindilinga, eyenziwe ngokusebenza kahle kakhulu eduze nendawo ububanzi obuncane bokuguga nokukhala. Uma kunesidingo sezinhlayiya ezinkulu zokudlulisa okuqinile, ngokuvamile kukhudlwana, ububanzi benombolo ye-impeller blade eyakhelwe ngaphakathi yehliswa ibe yizicucu ezingu-2-3, ngesisekelo sokuthuthukisa ukuguga kwepompo, ukusebenza kwepompo ye-hydraulic kunezinga elihlukile lokuncishiswa. .
I-slurry pump vice impeller shaft seal packing seal, uphawu, uphawu lomshini.
I-1, i-slurry pump packing seal iwukuthembela ngokuya ngomphumela wokuvala oqinile futhi othambile phakathi kokupakisha nomkhono we-shaft, uphawu lokupakisha kanye ne-shaft seal yamanzi shaft seal ukucindezela kwamanzi kufanele kudlule ukucindezela kokuphuma kwephampu ye-slurry engu-1.5 kg, imodi yophawu esetshenziswa kabanzi endaweni yokugqoka, iwasha yamalahle.
I-2, i-slurry pump mechanical seal mechanical seal, i-friction play umphumela wokuvala wamaphuzu aseduze wendandatho eguquguqukayo ne-static ihlukaniswe ngophawu lwemishini ngaphandle ngaphandle kohlobo lomjovo wamanzi lomshini wophawu, uhlobo lomjovo wamanzi lokugeza uphawu lomshini, uhlobo lomjovo wamanzi uphawu lomshini . Alukho uhlobo lomjovo wamanzi uphawu lwemishini aludingi ukwengeza amanzi ophawu lwe-shaft, impilo yesevisi cishe amahora angama-4000; Umjovo wamanzi ongaphandle wohlobo lomshini wokufaka uphawu kanye ne-shaft seal water shaft seal umfutho wamanzi we-1.5 kg, impilo yesevisi cishe amahora angama-6000; Uhlobo lomjovo wamanzi luwasha uphawu olusebenza ngomshini olunamanzi ophawu lwe-shaft oludingekayo, umfutho wamanzi we-shaft seal kunomfutho we-slurry pump outlet ongu-1.5 kg, impilo yesevisi cishe amahora angama-8000.
3, i-vice impeller ye-slurry pump seal ikhiqizwa yi-vice impeller pressure seal effect, imfuneko ye-slurry pump igeleza ingcindezi yokuhlehla ingeqi i-15% ye-slurry pump outlet pressure, lapho umsebenzisi wokuntuleka kwamanzi kulolu phawu.
