Slurry impeller technical zvinodiwa
Tarisa iyo shaft inopera kumeso runout A pane chinangwa chejenari ndechekudzivirira kuunganidza zvikanganiso, kana yakasungirirwa kudiki kurova zvakanyanya, inokanganisa chigadzirwa chemhando.Chiyero chimwe chiso nechiso chakafanana nendege yereferensi, asi kwete rimwe divi rakatarisana nejenari rekuyerwa kwechiso chekumhanya, chikonzero dzimwe nguva chinodiwa kune yekuyera nzira, dzimwe nguva kuitira kuti iratidze zviri nani kunaka kwekugadzirisa.
Runout uye parallelism hazvikurudzirwe muTafura 10-8 kutsauka kwechimiro uye chinzvimbo, kusarudzwa kwemazinga.Keyway centerline axis line ye skew inoreva mutsetse wepakati wekiyi pakona kuenda kuakisi ye shaft.Skew zvakare impeller isina kurodha kumusoro, kunyanya multi-stage pombi musangano wakaoma.
Naizvozvo, zvakanyanya kuomarara zvinodiwa zve skew, kazhinji 100 mm kureba keyway skew kushivirira 0.03 mm.Keyway offset inofambiswa mukufambirana neaxis mutsara .Kusanyanya kukanganisa pagungano, kushivirira kwakakura, kushivirira kwakawanda kwe 0.06 mm groove offset.Kuti uchengetedze buri repakati igomba kuitira kuti ugadzirise hwaro hwepakati.Ultrasonic kuyedzwa kwe shaft uye iyo magineti yekuona chinangwa ndeyekutarisa kana paine chakakanganisika mukati me shaft, iyo shaft kuona kuvimbika kwekushanda.Centrifugal pombi impeller ndiyo huru zvikamu.
Kuita uye impeller centrifugal pombi dhizaini nekugadzira (kukanda uye machining) inowirirana zvakanyanya nemhando.Impeller kuvaka kudhirowa uye tekinoroji zvinodiwa zvinoratidzwa muMufananidzo 10-2,slurry pombi mugadziriZvido zvehunyanzvi zveiyo impeller kutanga, yechipiri, zvitatu zvinogona hunyanzvi zvinodiwa uye yakafanana shaft, ona shaft chikamu.
Runout tolerances inokurudzirwa muTebhurari 10-7 chimiro uye kutsauswa kwechinzvimbo VII chiyero chakasarudzika, kushivirira kwechiso kunokurudzirwa muTafura 10-8 Chikamu VII geometric deviation level precision selection.Kunyange zvazvo symmetrical shape ye impeller , asi mukugadzirisa kwekukanda uye machining kukanganisa kunogara kuripo, ndicho chimwe chezvikonzero zvinokonzera centrifugal vibration.Saka iwe unofanirwa kuve wakadzikama impeller yakagadziriswa kubvisa huremu husina kuenzana.
General centrifugal pombi impeller static balance tolerances inokurudzirwa muTable 10-9 sarudzo.Impeller static balance test, chivharo chepamberi necheka nzira yekubvisa kusaenzana, iyo yekucheka ndiro ukobvu haifaniri kudarika 1/3.Kubva kumberi, dhizaini rekumashure rakacheka simbi yakawandisa, asi chikamu chekucheka chinofanira kubatanidzwa nedhisiki rakatsetseka.Impeller yechishanu zvinodiwa zvehunyanzvi, zvinowanzo furatirwa zviri nyore.Muchiito chekugadzira nekuda kwejecha kunze kwegill haina kukwana, asi izvo zvinokanganisa mashandiro echigadzirwa zvinowanzoitika, asiwo nekuita bvunzo kunyanya kugadzirisa, kupedza maawa akawanda, saka impeller inofanirwa kuve yakanyatso jecha kunze kwegill.
