ngati pompa yopatukana amakumana ndi mavuto pakugwira ntchito, nthawi zambiri timaganiza kuti kusankha pampu sikungakhale koyenera kapena koyenera. Kusankha pampu mopanda nzeru kungayambitsidwe chifukwa chosamvetsetsa bwino momwe mpope amagwirira ntchito ndi kuyikira, kapena kusaganizira mozama ndikuwunika momwe zinthu ziliri.

Zolakwa zambiri mu pompa yopatukana zosankha zikuphatikizapo:

1. Njira yogwiritsira ntchito pakati pa maulendo apamwamba ndi ocheperapo ogwiritsira ntchito pampu sichidziwika. Ngati mpope wosankhidwa ndi waukulu kwambiri, padzakhala "mzere wachitetezo" wochuluka kwambiri womwe umagwirizanitsidwa ndi mutu weniweni wofunikira ndi kutuluka, zomwe zidzachititsa kuti zigwire ntchito pansi pa katundu wochepa. Izi sizimangochepetsa mphamvu, komanso zimayambitsa kugwedezeka kwakukulu ndi phokoso, zomwe zimayambitsa kuvala ndi cavitation.

2. Kuthamanga kwakukulu kwadongosolo sikunatchulidwe kapena kukonzedwa. Kuti mudziwe mutu wocheperako wofunikira papampu yonse, zinthu zotsatirazi ziyenera kuganiziridwa:

2-1. Zopuma zochepa;

2-2. Kuthamanga kwakukulu kolowera pakugwira ntchito;

2-3. Osachepera ngalande mutu;

2-4. Kutalika kwakukulu koyamwa;

2-5. Kukana kwa mapaipi ochepa.

3. Pofuna kuchepetsa ndalama, kukula kwa mpope nthawi zina kumasankhidwa kupitirira malire ofunikira. Izi zikutanthauza kuti choyikapocho chiyenera kudulidwa mpaka kufika pamlingo wina kuti chikwaniritse malo ogwiritsira ntchito. Pakhoza kukhala backflow pa cholowetsa cholowera, amene angachititse phokoso kwambiri, kugwedera ndi cavitation.

4. Mikhalidwe yoyika pompano pamalopo saganiziridwa mokwanira. Ndikofunikira kukonza chitoliro choyamwa moyenera kuti zitsimikizire kuti zikuyenda bwino.

5. Mphepete mwa NPSHA ndi NPSH₃ (NPSH) yosankhidwa ndi mpope si yaikulu mokwanira, yomwe idzayambitsa kugwedezeka, phokoso kapena cavitation.

6. Zida zosankhidwa ndizosayenera (kuwonongeka, kuvala, cavitation).

7. Zida zamakina zomwe zimagwiritsidwa ntchito ndizosayenera.

Pokhapokha posankha chitsanzo chabwino akhoza kagawo kakang'ono pampu itsimikizidwe kuti ikugwira ntchito mokhazikika pamalo ogwirira ntchito ndipo kukonza kwa mpope kumatha kuchepetsedwa moyenera.
