Liwiro Lenileni
1. Kutanthauzira kwachangu kwachangu
Liwiro lenileni la mpope wamadzi limafupikitsidwa ngati liwiro lenileni, lomwe nthawi zambiri limayimiridwa ndi chizindikiro ns. Liwiro lapadera ndi liwiro lozungulira ndi mfundo ziwiri zosiyana. Liwiro lenileni ndi deta yokwanira yowerengedwa pogwiritsa ntchito magawo oyambirira Q, H, N, omwe amasonyeza makhalidwe a mpope wamadzi. Ikhozanso kutchedwa muyeso wokwanira. Zimagwirizana kwambiri ndi mawonekedwe a pump chopondera komanso magwiridwe antchito a mpope.

1. Q ndi H amatanthawuza kuthamanga kwa kuthamanga ndi mutu pakuchita bwino kwambiri, ndipo n amatanthauza liwiro la mapangidwe. Kwa mpope womwewo, liwiro lenileni ndi mtengo wake.
2. Q ndi H mu ndondomekoyi amatanthawuza kuchuluka kwa kayendedwe ka mapangidwe ndi mutu wa mapangidwe a pampu imodzi yokha. Q/2 imalowetsedwa m'malo mwa mpope woyamwa pawiri; Kwa mapampu amitundu yambiri, mutu wa choyikapo choyambirira uyenera kulowetsedwa m'malo mwa kuwerengera .

1. Pampu yokhala ndi liwiro lotsika kwambiri imatanthawuza mutu wapamwamba ndi kuyenda pang'ono, pamene pampu yokhala ndi liwiro lapadera imatanthawuza kutsika kwa mutu ndi kutuluka kwakukulu.
2. Choyikapo chomwe chili ndi liwiro lotsika kwambiri ndi chopapatiza komanso chachitali, ndipo chowongolera chokhala ndi liwiro lapadera ndi lalikulu komanso lalifupi.
3. Pampu yotsika kwambiri yothamanga imakhala ndi hump.
4, pampu yotsika kwambiri yothamanga, mphamvu ya shaft ndi yaying'ono pamene kutuluka ndi zero, kotero kutseka valve kuti muyambe. Mapampu othamanga kwambiri (pampu yosakanikirana, pampu ya axial flow) ali ndi mphamvu yayikulu ya shaft pakuyenda kwa zero, kotero tsegulani valavu kuti muyambe.
