Kufurira kweMvura Jet Focusing Tubes

Mune abrasive mvura jet kucheka, iyo tungsten carbide mvura jet inotarisa chubhu chikamu chakakosha. Mushure mezvose, iri muhubhu iyo iyo yakakwirira-inodzvinyirira mvura uye mabrasives inotarisa pane inobudirira yekucheka jet. Munguva iyi maitiro, maitiro emuviri muchubhu anokanganisa zvakanyanya kumhanya kwekupedzisira uye kurongeka kwejeti yekucheka pamwe nehupamhi hwekerf pane zvebasa.

Nekudaro, chimiro uye saizi yejeti yemvura inotarisa chubhu inopesvedzera sei?

Chinhu chakakosha chejeti yemvura inotarisa chubhu kureba kwayo uye nzvimbo yekupinza.

Mukubatana nenzvimbo yekupinda, kureba kwekupfeka-inodzivirira mvura jet chubhu inotarisisa kukurumidza uye kutarisa kwejeti inobuda. Jeti yemvura yakachena yakagadzirwa neorifice inowedzerwa nejecha rinoputika muimba yekuvhenganisa, iyo iri pamberi pechubhu inotarisa. Mukuita uku, zvese zviri zviviri zvakaringana inlet angle uye hurefu hwechubhu hudiki hunodiwa kugadzirisa mabrasive particles kune velocity uye kutungamira kwejeti remvura. Nokudaro, inogona kugadzira jet yakanyatsotarisa uye inobudirira yekucheka. Nekudaro, iyo cemented carbide inotarisa chubhu haifanirwe kunge yakareba nekuti kukweshera mukati memukati kunogona kuderedza jeti.

Iyo yemukati dhayamita yemvura jet nozzle chubhu yakakoshawo kune iyo chaiyo yakatarisa yekucheka jet.

Kazhinji, iyo inotarisisa chubhu gomba uye orifice inofanirwa kunyatso enderana. Iyo yakadzika, zvishoma kunge wave kupfeka inogona kucherechedzwa, kunyanya pachubhu inopinza. Kana kurongeka kusina kujeka, kupfeka kunowedzera uye kunokanganisa hutano hwejeti mushure menguva pfupi yekushandiswa. Izvi zvinogona kutungamirira mukutsauswa kwejeti yekucheka panzvimbo yekubuda kwechubhu uye kuora kwehutano hwekucheka pane workpiece. Zvimwe zvinhu zvinonyanya kukanganisa hupenyu hwechigadzirwa ndeye inlet velocity yejeti yemvura uye huwandu uye mhando yeabrasive uye, hongu, iyo yemhando yemhando yechubhu inotarisisa.

Iwo akajairwa saizi ye tungsten carbide mvura jet inotarisa nozzles:
