Mugga luminta wakhtiga runtime slurry shaqada, cadaadiska dareeraha bamka ee jidhka oo dhan waa mid aan sinnayn, aag cadaadis sare leh, waxaa jira aag cadaadis hooseeya.Tan iyo baahida qaabdhismeedka, waxaa jira nusqaamo badan oo ku jira jirka bamka, marka farqiga u dhexeeya cadaadiska cadaadiska, dareeraha ayaa ka soo qulqulaya aagga cadaadiska sare ilaa aagga cadaadiska hooseeya, qaybtan cadaadiska sare ee dareeraha ayaa dib ugu soo laabanaya. gobolka cadaadiska hoose, halka qulqulaya iyada oo functional tamarta waxaa la helay marka impeller ah, laakiin ma isticmaalka wax ku ool ah, laakiin wareegga jidhka bamka, sababtoo ah farqiga u si ay uga gudbaan iska caabin ah oo wada baabbi'iyey, khasaaraha tamarta this waxaa loo yaqaan khasaaraha mugga.
Sida dareeraha ka soo baxay qayb ka mid ah impeller ee bamka dib, oo aan la sii dayn ka baxay bamka, bamka dheecaan socodka heerka Q ee saamiga dhabta ah ee heerka socodka dhex impeller Q 'yaraan.
Kala soocidda khasaaraha mugga
(1) halka laga soo galo impeller, impeller iyo jidhka bamka uu leeyahay farqiga shaabadeynta yar.Cadaadiska gudaha daloolka godka matoorka matoorka oo ka sarreeya kan sare, sidaas darteed waxaa jira farqi yar oo ka yimaada dareeraha kaydka iyada oo loo marayo shaabadda dib ugu noqoshada soo-baxa impeller-ka.Qaybtan dareeraha ah sida kicinta dalabka guusha leh ayaa si wax ku ool ah looga faa'iidaystaa, khasaaruhuna waa in laga gudbo caabbinta farqiga shaabadda.Caadi ahaan, qaybtan ka mid ah lumitaanka tamarta waxaa loo yaqaanaa khasaaraha daadinta giraanta.Biyaha la heli karo waxay dhex maraan makaanikada qaacidada si ay u xisaabiyaan qaddarka ka daadanaya giraanta xidhidda q1 (m ^ 3 / s): dareeraha qalalan ama dareeraha adkaha leh ee ay weheliyaan bamka hadhuudhka, nadiifinta giraanta shaabadu waa inay ka weyn tahay qiimaha shaxda 2 -1 wax yar.Dhererka farqiga giraanta xiridda l waxaa lagu go'aamin karaa iyadoo loo eegayo qaab dhismeedka gaarka ah.
(2) Guud ahaan dheellitirka xoogga axial centrifugal ee labada hay'adood, sida dheellitirka daloolka (Jaantus 2-11) iyo saxanka dheelitirka iyo wixii la mid ah.Inkasta oo qayb ka mid ah dareeraha laga helay impeller tamarta, laakiin aan si wax ku ool ah looga faa'iidaysan iyo wada baabbi'iyey si ay uga gudbaan iska caabin by habka dheellitirka, kaas oo sidoo kale iska leh khasaaraha mugga ee khasaaraha tamarta.Marka la ansaxiyo xisaabinta saxanka dheellitirka bamka-marxalado badan ee qadarka dareeraha dareeraha ah waxa lagaga hadli doonaa cutubka VII.Marka la eego qadarka ka daadanaya godka dheelitirka waxaa lagu qiyaasi karaa qaacidada (2-13), waa joogitaanka waxtarka bamka daloolka dheelitirka guud ahaan 3-6%.
Intaa waxaa dheer, bamka marxaladaha badan, marka lagu daro labada qaybood ee kor ku xusan waxay ka tirsan yihiin khasaaraha mugga qulqulka, ma jiraan qayb ka mid ah daadinta mugga luminta.In bambooyin badan marxaladaha guud ahaan waa saxan xijaab heerka, tan iyo heerka dareeraha ka dib saxan xijaab cadaadis kala duwan,soo saaraha bamka slurrysidaas darteed qayb ka mid ah dareeraha iyada oo loo marayo heerka dib u galay farqiga saxan u dhexeeya dhinaca impeller ee nadiifinta ka hor, farqiga u daadinta dhexeeya heerka dareeraha, dhex impeller iyo hagi dib-u-celinta vane ka dib qaso dareere ka impeller ah, hagid vanes iyo ABM caleemaha, laakiin sidoo kale by farqiga heerka u dhexeeya impeller dib u celin ka hor, iyo wixii la mid ah.Maaddaama qaybtan dareeraha ah aysan soo marin impeller-ka, ma saameynayso socodka bamka, sidaas darteed qaybtan khasaaraha tamarta ma aha khasaaro mug leh.
