Codsiyada Axial Split Case Pump Impeller Applications
Waxaa jira arrimo badan oo la tixgeliyo marka la dooranayo axial kala qaybsan bamka iyo impeller si sax ah.
Marka hore, waxaan u baahanahay inaan ogaano halka dareeraha loo baahan yahay in la qaado iyo heerka socodka qulqulka. Isku darka madaxa iyo qulqulka loo baahan yahay waxaa loo yaqaan barta shaqada. Barta shaqadu waxay si toos ah ula xiriirtaa joomatari impeller ee loo baahan yahay. Codsiyada leh bamgareynta toosan ee dheer (madaxa sare) waxay u baahan yihiin matoorada dhexroorka dibadda ka weyn marka loo eego codsiyada leh bamgareynta gaaban ee toosan (pumpers).
Another consideration that is directly related to impeller size is the expected solids content in the application. Many applications have a variety of solids in the pumped media. These solids can range from small abrasive debris such as sand or metal shavings to fine fibrous materials to large solids the size of a baseball or larger. The pump and impeller selected must be able to pass these solids while avoiding clogging and damage from wear. Additional consideration must also be given to the equipment downstream of the axial split case pump. While a pump can be selected to pass a specific type of solids, it cannot be assumed that the downstream piping, valves, and other process equipment will have the same solids handling capabilities. Knowing the expected solids content in the liquid is critical not only to selecting the right size pump and impeller, but also to selecting the impeller style that best suits the application.
Mid ka mid ah kuwa ugu caansan ee wax ka qabta impellers waa impeller furan. Qalab-mareenkan waxa caadi ahaan loo isticmaalaa wasakhda iyo daawaynta biyaha wasakhda ah oo waxa uu leeyahay joomatari oo ay ku jiraan marinnada u dhexeeya garbaha oo dhinaca furan u jeedo meesha laga soo galo. Meelaha bannaan ee u dhexeeya daabyadu waxay siinayaan dariiq siman oo loogu talagalay impeller si uu ugu riixo adkaha soo socda ee daloolka nuugista impeller ilaa volute iyo ugu dambeyntii iyada oo loo marayo dheecaanka bamka.
Ikhtiyaarka kale ee lagu maarayn karo adkaha waa vortex-ka ama impeller-ka dib loo dhigay. Nooca impeller-ka waxa lagu rakibaa daasad dhexdeeda (samaynta meel bannaan oo ballaadhan oo u dhaxaysa impeller-ka iyo dekedda nuugista) oo waxay keentaa dhaqdhaqaaq dareere ah iyada oo loo marayo wareegyo ay abuurtay wareegga degdegga ah ee impeller. Inkasta oo habkani aanu ahayn mid waxtar leh, wuxuu bixiyaa faa'iidooyin badan marinka adkaha. Faa'iidooyinka ugu muhiimsan waa meel bannaan oo ballaaran iyo xannibaadda ugu yar ee marinka adag.
Pumps used at high altitudes have their own set of solids handling considerations. Since these applications typically use smaller piping, the solids passage size of the entire system must be considered, not just the pump. Typically, the axial split case pump manufacturers offering high-pressure pumps will include a strainer at the inlet to prevent large solids from entering the pump.
This is ideal for high-pressure applications where minimal solids are expected, but can cause clogging if enough solids accumulate around the screen surface.
There are many factors to consider when choosing the right axial split case pump and impeller, and understanding the various styles of pumps and impellers is often one of the most critical steps.
