Mavavu a Jet Hollow
Valve yamadzimadzi ndi mtundu wa valve womwe umagwiritsidwa ntchito mumayendedwe owongolera madzi. Vavu imeneyi imapangidwa ndi dzenje kapena dzenje pakati pake, zomwe zimapangitsa kuti madzi azitha kudutsamo.
Valve yamadzimadzi ndi mtundu wa valve womwe umagwiritsidwa ntchito mumayendedwe owongolera madzi. Vavu imeneyi imapangidwa ndi dzenje kapena dzenje pakati pake, zomwe zimapangitsa kuti madzi azitha kudutsamo. Amagwiritsidwa ntchito nthawi zambiri m'malo omwe kuthamanga kwambiri komanso kuwongolera kwamadzimadzi ndikofunikira. Valavu ya jet yopanda madzi nthawi zambiri imakhala ndi thupi lomwe lili ndi cholowera ndi chotulukira, komanso chotuluka kapena chimbale chomwe chimayang'anira kutuluka kwa madzi. Pamene valavu ili pamalo otsekedwa, orifice imalepheretsa kutuluka kwamadzimadzi. Pamene valavu imatsegulidwa mwa kusuntha orifice kutali ndi mpando, madzimadzi amatha kudutsa pakati pa dzenje ndikutuluka kudzera mumtsinjewo.
Mavavu amadzimadzi nthawi zambiri amagwiritsidwa ntchito m'madamu amadzi, komanso kupanga magetsi. Ndiwothandiza makamaka pakuwongolera kuthamanga kwambiri kapena kuthamanga kwambiri kwamadzimadzi, komwe kuwongolera kolondola komanso kugwira ntchito moyenera ndikofunikira. Mapangidwe ndi zipangizo zomwe zimagwiritsidwa ntchito muzitsulo za jet zowonongeka zimatha kusiyana malinga ndi momwe zimagwiritsidwira ntchito komanso mtundu wamadzimadzi omwe amawongoleredwa. Zinthu monga kupanikizika, kutentha, ndi kuyanjana kwa mankhwala ziyenera kuganiziridwa posankha valavu ya jet yopanda kanthu pa dongosolo linalake. Kusamalira ndi kuyang'anitsitsa nthawi zonse n'kofunika kuti zitsimikizidwe kuti ma valvewa akugwira ntchito moyenera komanso kupewa kutaya kapena kulephera kulikonse.
Mavavu athu opangidwa ndi ma hollow-jet atsimikizira kuti amagwira ntchito bwino pamafakitale opangira magetsi opangira magetsi amadzi ndi madamu amthirira. Amaonetsetsa kuti madzi atuluka kunja kapena m'matangi apansi pamadzi. Madziwo amawonjezeredwa ndi okosijeni nthawi yomweyo. Kupanga kwachitsulo kwapamwamba kwambiri kwa ma valves a hollow-jet ophatikizidwa ndi zotanuka / zitsulo kusindikiza kumapangitsa kuti mphamvu ziwonongeke popanda cavitation.
-Mapangidwe Apangidwe-
◆Poyika madamu, ma valve owongolera monga ma Hollow jet mavavu amaikidwa pambuyo pa ma valve agulugufe kumbali yakutulukira. Ma valve awa nthawi zonse amagwira ntchito ngati ma valve oyendetsa kapena owongolera. Ma valve a hallow jet opangidwa kuti aziwongolera kapena kuwongolera.
◆imagwira ntchito m'machitidwe operekera madzi popanda kugwedezeka kulikonse monga kutsegulira kwa valve.
-Ubwino-
◆ Kusintha kolondola
◆ Palibe cavitation
◆ Palibe kugwedezeka
◆Kugwira ntchito pamanja kumafunikira mphamvu zochepa. Mosasamala kanthu za momwe pisitoni ilili, kukakamiza kofunikira kuti musunthe pisitoni yotsegula ndi kutseka kwambiri ndiyofanana.
◆ Chifukwa chotulutsa mpweya palibe chomwe chimayambitsa chipwirikiti ndipo palibe chifukwa choyika nyundo yoletsa madzi kunsi kwa mtsinje.
