Chidule Chachidule cha Venturi Bore Nozzle

M'nkhani yapitayi, tinalankhula za mphuno yowongoka. Munkhaniyi, ma nozzles a Venturi adzafotokozedwa.

Mbiri

Kuti tione mbiri ya Venturi anabala nozzle, zonse zinayamba mu 1728. Chaka chino, Switzerland masamu ndi physics Daniel Bernoulli anasindikiza buku lotchedwa.Hydrodynamic. M'bukuli, adalongosola zomwe anapeza kuti kuchepa kwa kuthamanga kwa madzi kumayambitsa kuwonjezeka kwa liwiro lamadzimadzi, lomwe limatchedwa Mfundo ya Bernoulli. Kutengera Mfundo ya Bernoulli, anthu adayesa zambiri. Kufikira zaka za m'ma 1700, katswiri wa sayansi ya zakuthambo wa ku Italy Giovanni Battista Venturi anayambitsa Venturi Effect ---pamene madziwa amayenda mu gawo lophwanyika la chitoliro, kuthamanga kwa madzi kumachepa. Pambuyo pake Venturi anabala nozzles adapangidwa kutengera chiphunzitsochi m'ma 1950. Pambuyo pazaka zingapo akugwiritsa ntchito, anthu akupitilizabe kusinthira mphuno ya Venturi kuti igwirizane ndi chitukuko chamakampani. Masiku ano, ma nozzles a Venturi amagwiritsidwa ntchito kwambiri m'makampani amakono.

Kapangidwe

Nozzle ya Venturi inali yophatikizidwa ndi mathero osinthika, gawo lathyathyathya lowongoka, ndi malekezero osiyanasiyana. Mphepo yopangidwa imayenderera ku convergent pa liwiro lalikulu poyamba ndiyeno imadutsa gawo lalifupi lathyathyathya lolunjika. Mosiyana ndi ma nozzles owongoka, ma nozzles a Venturi amakhala ndi gawo losiyana, lomwe lingathandize kuchepetsavertexntchito kuti madzi amadzimadzi azitha kutulutsidwa pa liwiro lalikulu. Kuthamanga kwakukulu kungapangitse kuti ntchito ikhale yogwira ntchito kwambiri komanso kuti ikhale yochepa kwambiri. Venturi bore nozzles ndiabwino kuti azitha kupanga zambiri panthawi yophulitsa chifukwa cha kuphulika kwawo komanso kuthamanga kwamphamvu. Venturi bore nozzles amathanso kugawa tinthu ting'onoting'ono, motero ndi oyenera kuphulitsa malo okulirapo.

Ubwino & Kuipa

Monga tidanenera kale, ma nozzles a Venturi amatha kuchepetsavertexntchito. Chifukwa chake adzakhala ndi liwiro lapamwamba lamadzimadzi amphepo ndipo amatha kuwononga zinthu zocheperako. Ndipo iwo adzakhala ndi zokolola zapamwamba, zomwe zili pafupi ndi 40% kuposa mphuno yowongoka.

Kugwiritsa ntchito

Venturi bore nozzles nthawi zambiri amapereka zokolola zambiri zikaphulitsa malo akuluakulu. Chifukwa cha kuchuluka kwawo, amatha kuzindikira kuphulika komwe kumakhala kovuta kwambiri kupanga.

Ngati mukufuna kudziwa zambiri za kuphulika kwa abrasive, talandirani kuti mutilankhule kuti mudziwe zambiri.
