Karolong ea lipompo tsa metsi, haeba khetho e fosahetse, litšenyehelo li ka ba maemong a phahameng kapa tšebetso ea pompo e kanna ea se fihlelle litlhoko tsa sebaka seo. Joale fana ka mohlala oa ho etsa mohlala oa melao-motheo e meng eo pompo ea metsi e hlokang ho e latela.
Khetho ea pompo ea Suction ea Suction e lokela ho ela hloko lintlha tse latelang:
1. Lebelo:
Lebelo le tloaelehileng le ikemiselitse ho latela litlhoko tse fanoeng tsa moreki. Ka tlase lebelo la pompo e le 'ngoe, sekhahla se tsamaellanang le ho phahamisa se tla fokotseha. Ha u khetha mohlala, hoa hlokahala ha u sa khone ho sebetsana le ts'ebetso ea moruo, empa le maemo a sebaka, a apere bokhoni ba ho hanyetsa, boithati, jj.
2. Mokhoa oa NPSH:
NPSH e ka khethoa ho latela boleng bo fanoeng ke moreki, kapa ho latela maemo a ho kena-kenana ha pompo, mocheso o bohareng ba sepakapakeng.
Palo ea bophahamo ba pompo ea metsi (algorithm e bonolo: Ho latela khatello e tloaelehileng ea sepakapaka le metsi a tloaelehileng) e tjena:
Har'a bona: bophahamo ba bophahamo ba HG-jimetric
-Thosphic khatello ea metsi sebakeng sa ho kenya (e balime ho 10.333 tlasa khatello e tloaelehileng ea sepakapaka le metsi a hlakileng);

-Vaporization khatello ea hlooho; (Metsi a hlakileng a mocheso oa kamore e baloa ho 0,24m)
- E lumella NPSH; (Ho netefatsa polokeho, ho bala ho latela NPShr × 1.2, NPSHR bona Catalog)
Mohlala, The Npssh NPSHR = 4M: HG = 10.79 m (4 × (4 × 1 × ( E tlameha ho ba kholo ho feta boleng bo lekantsoeng, ke hore, boemo ba Inlet ea metsi bo ka ba kaholimo ho boleng bo lekantsoeng kaholimo ho mola oa mantlha oa moetsi).
Tse kaholimo e baloa tlasa maemo a mocheso o tloaelehileng oa mocheso, metsi a hlakileng le bophahamo bo tloaelehileng. Haeba Mocheso, matlotlo le bophahamo ba batho ba mahareng li haella le ho qoba ho litima, melao e amanang le eona e lokela ho khethoa le ho khetha foromo ea lipalo. Har'a bona, thempereichari le botebo ba semelo se baloa ho latela "khatello ea lijo tsa bofekhuni le letsoalo la metsi a litoropo tsa litoropo tsa litoropo naheng". NPSH e 'ngoe e lumelloang ke ho netefatsa polokeho, ho latela NPShr × 1.4 (boleng bona bo bonyane 1.4).
3. Ha khatello ea puo ea pompo ea pompo e tloaelehileng ke ≤0.2FA, ha sethala sa khatello + hloohong × 1,5 khatello ea khatello, Khetha ho latela lisebelisoa tse tloaelehileng;
