Chifukwa kugwiritsa ntchito pampu yolumala ndikochulukirapo, chikhalidwe cha madzi chimasamutsidwa nthawi zina chimakhalanso kusiyana kwakukulu, zochitika zosiyanasiyana zimakhala ndi zofunikira za kampuli zimafunikira magwiridwe antchito m'malo osiyanasiyana , pali mitundu yambiri ya pampu, yomwe nthawi zambiri imatha kutchulidwa molingana ndi mfundo ya ntchito ya pampu, ndipo kugwiritsa ntchito kwake kumatha kungokwezedwa. Malinga ndi mfundo yogwira pampuyo imatha kugawidwa pampu yolimba, pampu yopingasa ndi mtundu wina mapampu atatu
Mapampu othawa kwawo amadalira kusintha kwa ma voliyumu nthawi ndi nthawi kumwa mankhwalawo ndikusiya madzi, pamene kuchuluka kwa ntchito kumawonjezeka, kampu yoyamwa madzi; Mukamachepa, madzi amadzimadzi. Makhalidwe a Kinematic molingana ndi ntchito ya mtundu uwu pa nthawi yogawika:
1. Kubwezeretsa POMPRIMISMEM ATSOGOLO KUTI MUZISANGALIRA. Mtundu wamtunduwu ndi pampu ya pisitoni, piston, diaphragm chestnut ndi zina zotero.
Mapampu agalu amagwira ntchito ya mabungwe okhazikika a Axis. Mtundu wamtunduwu ndi pampu yamafuta, pampu yotchinga,miyala yamsodzimapampu oyenda.
Vane Winnut amadalira njira imodzi yothamanga kwambiri yothandizira kuti ikhale yotuluka, kuti ikwaniritse madzi. Malinga ndi madzi munjira yolowera pampu yopaka pampu yolumikizidwa:
1. Madzimadzi amadzimadzi amatuluka kudzera pampu, mphamvu ikukankhira madzi amayenda pomwe mphamvu ya centrifugal yomwe imapangidwa ndi kuzungulira kwa woyenda.
.
3. Kutuluka kwamadzimadzi mumadzimadzi mumabowo kupita ku shaft pampu mu ngosa zina, mphamvu ikukankhira madziwo pomwe mphamvu ya centrifugal yomwe idapangidwa ndi mphamvu ya axial.
4 - Kupukuta kwa Vortex Pump mu pampu yoyenda molunjika, ndikudalira zosintha zomwe zimapangitsa kuti pakhale vortice yopangidwa ndi kuyenda kwa madzi ndikutulutsa madzi.
Mitundu ina ya mapampu imadalira kwambiri madzi ena (amadzimadzi, mpweya) mphamvu kapena kinetic mphamvu hydrostatic yophunzitsa madzi. Chifukwa chake, wotchedwanso pampu ya hydrodynamic, monga mapampu a jet, mgonero wamadzi, etc. hammer.
Magawo oyamba a zinthu zazikulu za pampu ili ndi izi:
1, kutuluka kwa q
Kuyenda ndi kuchuluka kwa mtanda wamadzimadzi mu unit nthawi yotumiza (voliyumu kapena mtundu).
Voliyumu yoyenda ndi q adati, unit ndi: m3 / s, m3 / h, l / s etc ..
Kuyenda ndi QM kunati, unit ndi: t / h, kg / s.
Ubale womwe ulipo pakati pa maulendo othamanga ndi voliyumu ikuyenda:
QM = ρ q
Mu fomu ρ - kachulukidwe ka madzi (kg / m3, t / m3), kutentha kwabwinobwino madzi p = 1000kg / m3.
2, mutu wa h
Mutu ndi unit kulemera kwa miyala yamadzi yopumira kuchokera pampu yamiyala (itlet flaved pompo) mpaka miyala yopukutira ya mpweya. Mphamvu yogwira ntchito ndi madzi a Newtonian omwe amapezeka ndi pampu yamiyala. Chimbudzi ndi n? m / n = m, kutalika kwa madzimadzi amtengo wamsonkho, zizolowezi, zotchedwa M.
3, liwiro n
Kuthamanga ndiko kuthamanga kwa miyala ya miyala ya phulusa, kuwonetsedwa ndi chizindikiro n, gawo la R / min.
4, NTSH NPH
NPH imatchedwanso ukonde wabwino wothilira, umafotokozedwa makamaka magawo a cavitation. NPHSH MU IVUST gwiritsani ntchito Δ H.
kg / m3);
5, mphamvu ndi mphamvuKusankhidwa kwa Pampu Yosalala
Mphamvu yampukumm nthawi zambiri imatanthauzira mphamvu yolowera, yomwe ndi yoyambirira yomwe idayamba kuwuluka mphamvu ya miyala, motero imatchedwanso mphamvu ya Shaft, yoyimirire ndi P;
Pampu yamphamvu yamphamvu imatchedwanso mphamvu yotulutsa, kuyimira ndi pe. Ndiwo mphamvu yothandiza ya nthawi kuchokera ku miyala ya miyala yochokera ku madzi mu miyala yamiyala.
Chifukwa kukweza ndi mphamvu yogwira ntchito yolemetsa madzi olemera omwe amapezeka pampu yamiyala, kotero kukwera kwamafuta ndi kuthamanga kwa kampu ya miyala yomwe imapangitsa kuti mpweya uzikhala bwino - mphamvu:
Pe = ρ gqh (w) = gamma qh (w) formula ρ phomity - miyala ya miyala ya miyala - m3);
Gammal Gama - miyala yopumira madzi (n / m3);
Q - Kutuluka kamilulu (m3 / s);
H - mutu wa miyala (m);
G - Kuthamanga kwa mphamvu yokoka (m / S2).
Mphamvu Shaft P Ndi Mphamvu People Kutaya Mphamvu ya pampu ya miyala, kukula kwa kayendedwe ka kanjiro chogwira ntchito. Mpweya wolimba ngati mphamvu yogwira ntchito ndi ndulu yamagetsi, kugwiritsa ntchito η.
