Ngati mukufuna kudziwa chilichonse multistage vertical turbine pump , m'pofunikanso kudziwa zamadzimadzi ndi zamadzimadzi zomwe zimanyamula.

Zamadzimadzi ndi Zamadzimadzi

Pali kusiyana kwakukulu pakati pa madzi ndi madzi. Zamadzimadzi zimatanthawuza chinthu chilichonse chomwe chili pakati pa magawo olimba ndi gasi. Kaya chinthu chili mumkhalidwe wamadzimadzi zimatengera kutentha ndi mphamvu yomwe imakumana nayo, komanso momwe thupi limakhalira.

Madzi ndi chinthu chilichonse chomwe chimatha kuyenda mosalekeza ndipo chimatha kupanga chidebe chilichonse chomwe chili nacho. Ngakhale izi zikufotokozera bwino zamadzimadzi, zitha kugwiritsidwanso ntchito pofotokoza mpweya. Mwa kuyankhula kwina, zamadzimadzi zonse ndi zamadzimadzi, koma si madzi onse omwe ali mumadzimadzi. Chifukwa chake, nthawi zambiri, mawu oti "fluid" amagwiritsidwa ntchito m'mawu multistage vertical turbine pump, amatanthauza zamadzimadzi, chifukwa mapampu sanapangidwe kuti azinyamula mpweya.

Zamadzimadzi zimakhala ndi zinthu zazikulu zomwe zimafunikira kuganiziridwa pakupopera ntchito, zomwe ndi viscosity, kachulukidwe, komanso kuthamanga kwa nthunzi (kuthamanga kwa vaporization). Izi ndizofunikira kuti timvetsetse momwe madzi amachitira komanso kuti ndi pampu iti yomwe ili yoyenera kwambiri.

Viscosity imatanthawuza kukana kwa madzi kuti asayende, kapena momwe madzi "amamatira". Izi zikhudza kuthamanga kwa kuthamanga, mutu wonse, kugwira ntchito bwino, ndi mphamvu ya pampu yamagetsi yamitundu yambiri.

Kuchulukana kumatanthauza kuchuluka kwa chinthu chomwe chili mu voliyumu inayake. Popopa, imatchedwanso kachulukidwe wachibale (kukokera kwapadera), komwe ndi chiŵerengero cha kachulukidwe ka chinthu ndi kachulukidwe ka madzi pa kutentha kwina. Kachulukidwe ndi mphamvu yokoka yapadera imafunika kuti mudziwe mphamvu zomwe zimafunikira kuti zisunthire madzimadzi limodzi ndi ena.

Kuthamanga kwa nthunzi ndiko kuthamanga komwe madzi amayambira kusungunuka (nthunzi), ndipo ndikofunikira kuyang'anira izi pamapampu. Ngati kuthamanga mu mpope ndi wotsika kuposa kuthamanga kwa vaporization kwamadzimadzi, cavitation imatha kuchitika.

Kumvetsetsa kusiyana pakati pa zamadzimadzi ndi zamadzimadzi komanso momwe zamadzimadzi zimakhalira ndizofunikira kwambiri pakugwira ntchito kwa pampu yamagetsi yoyimirira yambiri.
