Mapampu a Madzi a Moto Ogwiritsa Ntchito Zosiyanasiyana

Momwe mungasankhire pakati pa mapampu opingasa ndi ofukula ndi makina amadzi amoto?

Pompo ya Madzi a MotoMalingaliro

Pampu ya centrifugal yoyenera kugwiritsa ntchito madzi amoto iyenera kukhala yokhotakhota yokhazikika.Pampu yotereyi imakhala yofanana ndi kufunikira kumodzi kwakukulu kwamoto waukulu muzomera.Izi nthawi zambiri zimatanthawuza moto waukulu mugawo lalikulu kwambiri lazomera.Izi zimatanthauzidwa ndi mphamvu yovotera ndi mutu wovotera wa seti ya pampu.Kuonjezera apo, pampu yamadzi amoto iyenera kusonyeza mphamvu yothamanga kwambiri kuposa 150% ya mphamvu yake yovomerezeka ndi oposa 65% ya mutu wake wovotera (kutulutsa kuthamanga).M'malo mwake, mapampu amadzi amoto osankhidwa amapitilira zomwe tafotokozazi.Pakhala pali mapampu ambiri osankhidwa bwino amadzi amoto okhala ndi ma curve ochepa omwe angapereke zambiri kuposa 180% (kapena 200%) ya mphamvu zowerengedwa pamutu komanso kuposa 70% ya mutu wonse wowerengedwa.

Matanki awiri kapena anayi amadzi amoto ayenera kuperekedwa kumene gwero loyamba la madzi amoto lili.Lamulo lofananalo limagwira ntchito pamapampu.Payenera kuperekedwa mapampu awiri kapena anayi.Kukonzekera kofala ndi:

● mapampu awiri amagetsi oyendera madzi amoto (imodzi yogwira ntchito ndi imodzi yodikirira)

● mapampu amadzi amoto oyendetsedwa ndi injini ya dizilo (imodzi yogwira ntchito ndi imodzi yodikirira)

Vuto limodzi ndi loti mapampu amadzi ozimitsa moto sangagwire ntchito kwa nthawi yayitali.Komabe, pamoto, aliyense ayenera kuyambika nthawi yomweyo ndikupitiriza kugwira ntchito mpaka motowo uzimitsidwa.Chifukwa chake, zinthu zina zimafunikira, ndipo pampu iliyonse iyenera kuyesedwa nthawi ndi nthawi kuti iwonetsetse kuti imayamba mwachangu komanso yodalirika.

Pampu Zopingasa motsutsana ndi Mapampu Oyima

Mapampu opingasa centrifugal ndi mtundu wa pampu wamadzi wamoto womwe anthu ambiri amakonda.Chifukwa chimodzi cha izi ndi kugwedezeka kwakukulu komanso kapangidwe kake kamene kamakhala kosatetezeka ka mapampu akuluakulu oyima.Komabe, mapampu oyimirira, makamaka mapampu amtundu wa shaft turbine, nthawi zina amagwiritsidwa ntchito ngati mapampu amadzi amoto.Nthawi zomwe madzi amakhala pansi pa discharge flange centerline, ndipo kupanikizika sikukwanira kuti madzi apite ku mpope wamadzi amoto, seti yapampu yamtundu wa shaft turbine ingagwiritsidwe ntchito.Izi zimagwira ntchito makamaka pamene madzi a m'nyanja, maiwe, zitsime, kapena m'nyanja akagwiritsidwa ntchito ngati madzi amoto (monga gwero lalikulu kapena ngati chosungirako).

Kwa mapampu osunthika, kulowetsedwa kwa mbale zapampu ndikukonzekera koyenera kwa ntchito yodalirika ya mpope wamadzi amoto.Mbali yoyamwa ya mpope woyimirira iyenera kuyikidwa m'madzi, ndipo kulowetsedwa kwa choyikapo chachiwiri kuchokera pansi pa mbale ya mpope kuyenera kupitirira mamita atatu pamene mpope umagwiritsidwa ntchito pamtunda wake wothamanga kwambiri.Mwachiwonekere, izi ndizokonzekera bwino, ndipo tsatanetsatane womaliza ndi kulowa pansi pamadzi ziyenera kufotokozedwa nthawi ndi nthawi, mutatha kukambirana ndi wopanga mpope, akuluakulu amoto am'deralo ndi ena okhudzidwa.

Pakhala pali zochitika zingapo za kugwedezeka kwakukulu m'mapampu akuluakulu oyimirira amadzi amoto.Chifukwa chake, maphunziro osunthika osamalitsa ndi kutsimikizira ndikofunikira.Izi ziyenera kuchitidwa pazinthu zonse zamakhalidwe amphamvu.
