--Utloisisa venturi nozzle ho tsoa likarolong tse tharo

Abrasive Blasting, e le mokhoa oa ho qeta bokaholimo oo ka kakaretso o kenyelletsang ts'ebeliso ea mochini o hatellang moea le mochini o qhomisang, ke ho fafatsa likaroloana tse hohlang sebakeng se hlokahalang hore se be boreleli kapa se be mahoashe.

Nozzle, e le ntho ea bohlokoa ea ho qhomisa, e tsoetse pele ho latela litlhoko tsa linako. Ho ne ho e-na le li-nozzles tse otlolohileng feela bohareng ba bo-1950. Leha ho le joalo, motho ea neng a li qhomisa o ile a fumana bothata ba tsona ka lebaka la ho tsofala le ho hoholeha ka hare. 'Me ka nako eo, mokhoa o sebetsang hantle oa ho phatloha, venturi nozzle, o hlahile. Joale li-nozzles tsa venturi ke eng? A re e shebeng ka botlalo.

Sebopeho sa Venturi Nozzle

Mabapi le ponahalo, venturi nozzle e arotsoe likarolo tse tharo. Ntlha ea pele, e qala ka sebaka se selelele se pota-potiloeng se pota-potiloeng, se lateloa ke karolo e khutšoanyane e otlolohileng e bataletseng, ebe e na le qetello e telele e khelohang e fetohang e pharaletseng ha e fihla haufi le molomo oa molomo. Moqapi o joalo o thusa ho eketsa katleho ea mosebetsi ka 70%, hona see se finyelloa joang?

Moea le abrasive li kena ka sekoting ka sekoting se selelele se kopanyang ebe se phallela karolong e khuts'oane e otlolohileng ha khatello e fokotseha ka nako eo, e leng se bakang phapang ea khatello lipakeng tsa kahare le kantle. Phapang ena ea khatello e fana ka matla a ka ntle bakeng sa likaroloana tsa abrasive. Ha abrasive e tloha molomong, lebelo le phahame habeli ho feta la nozzle e otlolohileng. Kahoo bokaholimo bo hloeka ka katleho.

Mefuta ea Venturi Nozzle

The venturi blasting nozzle e na le mekhahlelo e fapaneng e arotsoeng ho tloha mahlakoreng a fapaneng. Ka mohlala, ho ea ka pono ea ho kena, e arotsoe ka mokhoa o le mong oa ho kenya le ho kenya habeli. Ka kakaretso e arotsoe ka boron carbide, silicon carbide, le tungsten carbide ka thepa ea liner. Ho feta moo, mofuta oa khoele o arotsoe ka khoele e mahoashe le khoele e ntle.
