ka hortag luminta bamka slurry

Luminta mugga iyo si looga hortago luminta bamka dareeraha ah

Luminta mugga centrifugal china slurry bamka xirmada giraanta luminta, luminta dheelitirka u dhexeeya hay'adaha iyo heerka khasaaraha daadinta daadinta.

Luminta dareeraha giraanta shaabadda

In godka impeller ah , giraanta shaabadeynta ee shaqada bamka slurry china, sababtoo ah siddooyinka shaabadeynta labada dhinac waxaa jira kala duwanaansho cadaadis ah , dhinaca cadaadiska outeller impeller waa qiyaastii hal dhinac oo ka mid ah cadaadiska gudaha impeller , sidaas darteed waxaa mar walba jiri doona. qayb ka mid ah dareeraha ka soo baxa marinka impeller ilaa dareeraha gelitaanka impeller .Qaybtan dareeraha ah ee laga helay tamarta impeller , laakiin dareeraha looma dirin, sidaas darteed hoos u dhigista qadarka biyaha bamka slurry china.Dhammaan tamarta loo isticmaalo si looga adkaado daadinta giraanta shaabadda dareeraha ah ee caabbinta.
Sida iska cad, inta uu sii weynaado dhexroorka giraanta shaabadda Dw , ayaa aad u liidata labada dhinac ee kala duwanaanshaha cadaadiska , way sii badanaysaa qadarka dheecaanka .Wixii fikrado ah oo ku saabsan bambooyinka dareeraha shiinaha, si loo yareeyo qadarka qulqulka si loo hagaajiyo waxtarka bamka slurry china waa in la oggolaadaa kiiska xiritaanka farqiga giraanta.Guud ahaan qiyaastii wadarta guud ee nadiifinta dhexroorka shaabadda 0.002, sida Dw = 200 mm, wadarta nadiifinta 0.40 mm.Marka la isku keeno, giraanta shaabadda si qoto dheer uma weyna, haddii kale, qadarka dheecaanku wuu kordhi doonaa.Tallaabooyin kale oo muhiim ah oo loo isticmaalo in lagu kordhiyo caabbinta habka giraanta shaabadda si loo yareeyo qadarka dheecaanka , kordhinta caabbinta giraanta shaabadda waxaa laga sameeyaa maze , zigzag , iwm. kordhinta iska caabinta jidka .
Diidashada giraanta shaabadda , iyo xaaladaha qaarkood waxay keeni kartaa khalkhal gudaha marinka impeller , markaa naqshadayntu waa inay si macquul ah u samaysaa giraanta shaabadda .

Marka labaad, habka dheelitirka ayaa lumaya khasaaraha

Qaar badan oo ka mid ah bamka slurry china centrifugal , axial thrust dheelitirka muuqaalka hay'adaha: sida dheellitirka godadka , xakamaynta dheelitirka, saxanka dheelitirka.Maadaama ay jiraan laba dhinac oo isku dheeli tiran habka kala duwanaanshaha cadaadiska , oo sidaas awgeed qayb ka mid ah dareeraha dareeraha ah ee ka imanaya gobolka cadaadiska sare ilaa gobolka cadaadiska hooseeya .Qiyaastii 5% si loo dhimo daloolka daadsan waxay isu dheellitiraysaa waxtarka bamka dareeraha shiinaha.Xarumaha saxanka dheelitirka , daadinta ayaa xisaabisa 3% socodka shaqada , laakiin qaar ka mid ah bamka slurry china ee cadaadiska sarreeya ayaa ka weyn tan;si loo yareeyo khasaaraha daadinta waxaa la dhimi karaa dheellitirka dhexroorka saxanka D iyada oo aan wax saameyn ah ku yeelan xaalada ka-hortagga miisaanka '.

Seddexaad, khasaaraha daadinta isdhexgalka

In bamka slurry china volute multi-heer , kala fogaansho heerka labada dhinac ee saxanka cadaadiska kala duwan , sidaas darteed waxaa jira khasaaraha daadinta , sida ay habaynta hay'adaha kala duwan , heerka cadaadiska labada dhinac ee taarikada spacer noqon kartaa aasaasiga ah. dugsiga sare ama sare , marxaladaha badan ayaa kala duwan , ka dibna aad u daran daadinta inta u dhaxaysa heerka qaybinta , sidaas darteed halkan waxaa si ballaaran loo isticmaalaa ka mid ah shaabadda tallaabo tallaabo.

Intaa waxaa dheer, qaybta bamka dareeraha ee shiinaha ee heerar badan, waxaa jira daadinta marxaladaha dhexdooda.Laakiin tani waa daadinta inta u dhaxaysa heerka hore loo sheegay way ka duwan tahay, sababtoo ah qaybtan dareeraha ah kuma daadinayso impeller , kama tirsan tahay khasaaraha mugga .Halkan, heerka cadaadiska agagaarka saxan xijaab , cadaadisay by saamaynta faafin ee vanes ee qaybta impeller -side iyo farqiga nuugista ( u dhiganta impeller centrifugal ah ) sababay.Doorka cadaadiska kala duwan , daadinta heerka dareeraha ee dhexda u dhexeeya guddiga ka hor inta aanad gelin dib-u-celinta farqiga impeller , iyo hagaha hagaha, caleen ABM ( vanes hagaha neefsashada ) oo dib ugu noqo farqiga u dhexeeya heerka, ku celi habka.In kasta oo heerka qulqulka dareeraha ee qaybaha kala duwan ee shiinaha uusan ka tirsanayn khasaaraha mugga, laakiin waa wareeg wareeg ah isticmaalka bamka dareeraha Shiinaha.Intaa waxaa dheer, qayb ka mid ah dareeraha iyada oo loo marayo hagaha hagaha, dhuunta dhuunta waxay keeni doontaa hoos u dhaca qaybta waxtarka leh (ie, daadinta dareeraha waxay qaadataa qayb ka mid ah qaybta iskutallaabta), waxay kordhin doontaa heerka socodka halkan, taasoo keenaysa khasaare dheeri ah oo biyo ah. .Sida laga soo xigtay "Centrifugal china slurry bamka naqshadeynta saldhigga," buug ku saabsan: bamka dareeraha shiinaha ee heerar badan, oo ah heerka qulqulka 20 l / s, farqiga u dhexeeya heerka wuxuu hoos u dhacayaa 0.75 mm ilaa 0.25 mm, tirada daadinta isdhexgalka. q hoos u dhaca 0.7 litir/sek.hoos u dhigista q awgeed, qulqulka dhex mara faashado ayaa hoos u dhacaya, hoos u dhigaya heerka qulqulka dhuunta, hoos u dhigista biyaha lumay ee faaruqinta dhinaca ayaa hoos u dhacay, sidaas awgeed hoos u dhigista luminta saxanka impeller, markaa waxtarka bamka slurry china ayaa la wanaajiyey ilaa 5%.
