Liwiro Lapadera
1. Tanthauzo la liwiro lenileni
Liwiro lenileni la pampu yamadzi limafupikitsidwa ngati liwiro lenileni, lomwe nthawi zambiri limaimiridwa ndi chizindikiro cha ns. Liwiro lenileni ndi liwiro lozungulira ndi malingaliro awiri osiyana kotheratu. Liwiro lenileni ndi deta yonse yowerengedwa pogwiritsa ntchito magawo oyambira Q, H, N, omwe akuwonetsa makhalidwe a pampu yamadzi. Ikhozanso kutchedwa muyezo wokwanira. Imagwirizana kwambiri ndi mawonekedwe a pampu yoyimitsa ndi momwe pampu imagwirira ntchito.
Fomula yowerengera ya Specific Speed ku China
Fomula yowerengera ya Specific Speed kunja
1. Q ndi H amatanthauza kuthamanga kwa madzi ndi mutu pamlingo wapamwamba kwambiri, ndipo n amatanthauza liwiro la kapangidwe. Pa pampu yomweyi, liwiro lenilenilo ndi mtengo winawake.
2. Q ndi H mu fomulayi zimatanthauza kuchuluka kwa kayendedwe ka kapangidwe ndi mutu wa kapangidwe ka pampu imodzi yopopera imodzi. Q/2 imalowetsedwa m'malo mwa pampu yopopera kawiri; Pa mapampu ambiri, mutu wa impeller ya gawo loyamba uyenera kulowetsedwa m'malo mwa kuwerengera.

| Liwiro lenileni | 30 | 80 | 150 | 300 | 500 |
1. Pampu yokhala ndi liwiro lochepa imatanthauza mutu waukulu ndi kuyenda pang'ono, pomwe pampu yokhala ndi liwiro lalikulu imatanthauza mutu wotsika ndi kuyenda kwakukulu.
2. Impeller yokhala ndi liwiro lochepa ndi yayitali komanso yopapatiza, ndipo impeller yokhala ndi liwiro lalikulu ndi yayikulu komanso yayifupi.
3. Pampu yothamanga pang'ono imakhala ndi hump.
4, pampu yothamanga pang'ono, mphamvu ya shaft ndi yochepa pamene madzi akuyenda ndi zero, kotero tsekani valavu kuti muyambe. Mapampu othamanga kwambiri (pampu yosakanikirana yamadzi, pampu yoyenda pang'onopang'ono) ali ndi mphamvu yayikulu ya shaft pa zero, choncho tsegulani valavu kuti muyambe.
