Kunezici eziningi okufanele zicatshangelwe lapho ukhetha i- iphampu yecala lokuhlukaniswa kwe-axial kanye ne-impeller ngendlela efanele. 

Okokuqala, sidinga ukwazi ukuthi uketshezi ludinga ukuthuthwa kuphi nokuthi yiliphi izinga lokugeleza. Inhlanganisela yekhanda nokugeleza okudingekayo kubizwa ngokuthi iphoyinti lomsebenzi. Iphuzu lomsebenzi lihlobene ngokuqondile nejometri ye-impeller edingekayo. Izinhlelo zokusebenza ezinokumpompa okude okuqondile (ikhanda eliphezulu) zidinga ama-impeller amakhulu amakhulu angaphandle kunezinhlelo zokusebenza ezinokumpompa okufushane okuqondile (ukupompa).

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.

Enye yezinto eziqinile ezibamba ama-impeller yi-impeller evulekile. Lesi siphehli sivame ukusetshenziswa ekuhlanzeni indle namanzi angcolile futhi sinejiyomethri ehlanganisa amaphaseji phakathi kwama-blades nohlangothi oluvulekile olubheke endaweni yokungena. Izikhala phakathi kwama-blades zinikeza indlela ebushelelezi yokuthi i-impeller isunduze izinto eziqinile ezingenayo zisuka embotsheni yokudonsa i-impeller ziye ku-volute futhi ekugcineni ngokukhishwa kwepompo.

Enye inketho yokuphatha okuqinile yi-vortex noma i-impeller ephelile. Lolu hlobo lwe-impeller lufakwe ngaphakathi kwe-casing (ukudala indawo enkulu evulekile phakathi kwe-impeller kanye ne-suction port) futhi idonsa ukunyakaza koketshezi ngama-vortices adalwe ukujikeleza okusheshayo kwe-impeller. Yize le ndlela ingasebenzi kahle, ihlinzeka ngezinzuzo eziningi zokudlula okuqinile. Izinzuzo eziyinhloko yisikhala esikhulu samahhala kanye nokuvinjwa okuncane kokudlula okuqinile.

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.
