Venturi nozzle: mfundo zikugwira ntchito, kulongosola, ntchito

Mapaipi zolinga zosiyana ayenera kukhala mayunitsi sayansi, imene miyezo anapangidwa chilengedwe serviced. Izi imakhudzanso mipope ochiritsira madzi, ndi zomangamanga gasi, ndiponso apadera maofesi mafakitale ntchito ndi zakumwa wapadera mankhwala. Nthawi zonse njira imeneyi amapereka zipangizo zina zapadera madera flowmeters. Mmodzi wa wokongola kwambiri kuti anthu a ntchito za miyambo ya zida amenewa ndi venturi nozzle ndi anaikapo mu ena mfundo kayesedwe. chigawo ichi zambiri ubwino, koma ntchito zina zabwino kuganizira posankha lachitsanzo makamaka.

General mudziwe nozzle ndi

Ntchito yaikulu ya nozzle ndi - ndi chilengedwe muyeso zimene makamaka zimatenga chandamale madzi. Pamene mbali anatengera si kwambiri kuthekera kukhudzana ndi zakumwa zosiyanasiyana katundu wawo ngati mwayi structural. chakuti nozzle kapena venturi, akhoza kukhala ndi mlingo akadakwanitsira a kuthamanga pa nthawi ya chigawo cha sing'anga. Ie kuchepetsa a ngalande, ndithudi, zimakhudza chizindikiro ichi, koma osati ngati mmene zinalili ndi mitundu ina ya flowmeters.

Pali mbali inanso yofunika kwambiri. Mfundo yakuti khalidwe la kudutsa miyezo madzi voliyumu nthawi zambiri anakhudzidwa ndi njira awiri amene ndi metering chipangizo ndi gwero sing'anga. Ntchito, venturi pafupifupi sasintha lolondola muyeso malingana magawo njira.

chipangizo

chipangizo yaing'ono imeneyi mawonekedwe a mipope, zomwe zida amapereka malo zamakono, cholinga kuchita kuyeza ntchito. Childs, pakati, i.e. gawo chapakati nozzle ndi, overtighten achepetsa imene mbali imodzi chimafikira m'chipinda chapadera metering ndi kutsegula kwa kuthamanga wambiri. Kumbali ina ya mtundu chubu ndi n'kukhala phirilo ndi ndipamene khosi ndi. Apa ndi mabowo ochepa kusankha kuthamanga, komanso diffuser. Childs, mpope ndege chikugwirizana mbali kaya mwachindunji kapena kudzera mwa zovekera wapadera ukhondo.

Mwa ubwino structural izi akatswiri mankhwala cholembedwa ndi dzuwa mu zikhalidwe yochepetsetsa ya payipi ya. Komabe, pali kuphatikiza kwambiri kwa ojambula zithunzi zambiri. Iye ndi chitsanzo chosavuta cha nozzle unsembe.

Kodi venturi?

chipangizo unatchedwa wasayansi Italy chifukwa kwambiri kuti yatsegula zotsatira kuthamanga kuchepetsa, pamene ntchito madzimadzi umadutsa gawo mwapang'ono. Ndi mfundo imeneyi, wodzilemekeza ndi lamulo la Bernoulli, zikugwira ntchito machubu amenewa. Zochita izi zikutanthauza kuti madzi akudutsa chigawo mwapang'ono, imene pali wapadera kusankha kuthamanga annular chipinda, omwe amaperekedwa ndi nozzle venturi. Mfundo ntchito kumaphatikizapo mogwirizana kwa kumaliseche njira muyeso zipangizo mwachindunji. Choyezera zolondola, makamaka Akutsatira kuthamanga n'zotsimikizira, kumene akuimira mu mawonekedwe a chipangizo ndi analogi ndi chipangizo yadigito.

makhalidwe a

Muyezo waukulu kusankha machubu awa - awiri khalidwe. The akamagwiritsa kwambiri ambiri ali mu osiyanasiyana pa 6 ndi 12 mm. Palinso zamitundu zikuluzikulu zimene ziyenera anasankha kwa payipi makamaka. N'zotheka ntchito adaputala azamagetsi ndi kukula koyenera choncho okhwima kusintha pansi nozzle yeniyeni si kofunika. Komanso awiri ndi zofunika kwambiri zomwe unapangidwa venturi kapena metering mavavu ambiri zovuta. Kawirikawiri ntchito ngati maziko dzimbiri kapena mpweya zitsulo. Komabe, ntchito ndi zoteteza katundu kwakukulukulu zimadalira mtundu wa ❖ kuyanika. Akatswiri amalangiza kuonetsetsa durability bwino zitsanzo ankachitira enamel kapena phunziroli amene amateteza, mwa zina, ndi kwa adani mankhwala. Ngati tikulankhula za unsembe mu njira mafakitale, yabwino yothetsera mawu a kudalirika adzakhala otentha kuviika kanasonkhezereka ❖ kuyanika.

mitundu

Kusiyana chachikulu ndi structural m'njira yakuti ena mwa luso ndi mamangidwe wapadera. Mwachitsanzo, mtundu zofanana nozzles, yomwe osewera taper gawo popanda mankhwala. zitsanzo izi amapangidwa jekeseni ntchito mchenga wapadera masanjidwewo ndi processing yekha poyera mbali ya kupindika ndi khosi. zosintha zambiri zovuta ndi zitsanzo zimene zimapereka athandizira ndi chisanadze processing malo, zomwe kucheza ndi mpope ndege Mabaibulo osiyanasiyana. Pankhaniyi m'munsi chapakati angathe kuchitidwa popanda processing zapadera.

Kusiyana yaikulu ku mitundu zatchulidwazi si chopangidwa ndi jekeseni ndi njira kuwotcherera. Pankhaniyi, gawo tapered akhoza akuyendera mu mzere woongoka, mu mawonekedwe anamaliza.

Minda ya ntchito

mbali kandalama chifukwa onse nthawi sagwirizana nazo njira nozzles ntchito. Makamaka, zolimba wa mtundu uwu wakhala ntchito magawo jekeseni amene ntchito molumikizana ndi mapampu anati ndege. zimagwirira amenewa ntchito compressing mpweya zosakaniza nthunzi madzi, komanso potumiza malo kuthamanga. Simungakhoze kuchita popanda ngati dongosolo nozzle ndi mpweya kuchapa ena yofanana. Mwachitsanzo, nozzle ndi okonzeka ndi liwiro scrubber amene Zosefera serviced osakaniza micron ndi submicron particles. Zida za mtundu uwu ntchito zina matenthedwe ndi nthunzi boilers, koma advantageously ku dera mafakitale.

Ubwino ndi kuipa kwa venturi nozzle

The undoubted ubwino mavavu zikugwira ntchito pa Venturi tingati akhoza zimachitika mu kuthekera kwa khazikitsa ndi mfundo yosiyana magawo a ngalande chakudya. Komabe, kuti tizigwiritsa ntchito mwayi ayenera poyamba kukonzekera ndi adaputala azamagetsi yoyenera. Mwachitsanzo, ngati anasankha venturi nozzle kusiteshoni ya mpope zikugwira ntchito mu nyengo zosiyana, malingana ndi zofuna hayidiroliki siyana voliyumu ya otaya madzimadzi - motero, kusintha ndi kuika chakudya chodalirika kwambiri.

Koma zovuta, iwo kuchepetsedwa kwa fragility za ntchito ya mipope kuti mulibe apamwamba ❖ kuyanika zozitetezera. Komano, chitsanzo ndi kukhalapo kwa mankhwala amakono pamwamba kwambiri ngati mtengo kwambiri.

Pomaliza

Modern msewu mapaipi zolumukizidwa ndi malo ikukoka zikukangalika umasamutsidwa ku makina zida polojekiti ndi kasamalidwe ndi oyamba a matabwa amagetsi. Mu ena magawo zinchito za ntchito polojekiti ndi chingwe zida ntchito.

Mwina nozzle venturi ndi imodzi mwa zipangizo zochepa mu kalasi yake, imene dzuwa ntchito zachokera pa mfundo thupi kulamulira. Njira kusakanikirana kwa nkhani mu dongosolo piping ndipo amachititsa muyeso molondola ndi kochepa kungasokoneze kugwira ntchito njira yaikulu. Chinthu china ndi kuti asunge ntchito akadakwanitsira amafuna yokonza zonse akayezetsa mayunitsi.
