Lawula I-Valve Noise kanye ne-Cavitation

Isingeniso

Umsindo ukhiqizwa ngokuhamba koketshezi ngevalvu.Kulapho kuphela umsindo ongathandeki lapho ubizwa khona ngokuthi 'umsindo'.Uma umsindo udlula amazinga athile ungaba yingozi kubasebenzi.Umsindo futhi uyithuluzi elihle lokuxilonga.Njengoba umsindo noma umsindo udalwa ukungqubuzana, umsindo omkhulu ubonisa umonakalo ongenzeka ngaphakathi kwevalvu.Umonakalo ungabangelwa ukungqubuzana ngokwako noma ukudlidliza.

Kunemithombo emithathu eyinhloko yomsindo:

-Ukudlidliza komshini
- Umsindo we-Hydrodynamic
- Umsindo we-Aerodynamic

Ukudlidliza Komshini

Ukudlidliza komshini kuwuphawu oluhle lokuwohloka kwezingxenye zamavalvu.Ngenxa yokuthi umsindo okhiqizwayo uvamise ukuba namandla kanye nemvamisa ephansi, ngokuvamile akuyona inkinga yokuphepha kubasebenzi.Ukudlidliza kuyinkinga kakhulu ngama-stem valves uma kuqhathaniswa nama-cage valves.Ama-valve ekheji anendawo enkulu yokusekela ngakho-ke mancane amathuba okuba abangele izinkinga zokudlidliza.

Umsindo we-Hydrodynamic

Umsindo we-Hydrodynamic ukhiqizwa ekuhambeni koketshezi.Lapho uketshezi ludlula esivimbelweni futhi kwenzeka ushintsho lwengcindezi kungenzeka ukuthi uketshezi lwakha amabhamuza omhwamuko.Lokhu kubizwa ngokucwayiza.I-Cavitation nayo iyinkinga, lapho amabhamuza akheka khona kodwa abe esegoqa.Umsindo odalekayo ngokuvamile awuyingozi kubasebenzi, kodwa uyinkomba enhle
komonakalo ongaba khona wokunquma izingxenye.

Umsindo we-Aerodynamic

Umsindo we-aerodynamic udalwa ukunyakaza kwamagesi futhi ungumthombo oyinhloko womsindo.Amazinga omsindo akhiqizwayo angaba yingozi kubasebenzi, futhi ancike enanini lokugeleza kanye nokwehla kwengcindezi.

I-Cavitation kanye ne-Flashing

Iyabaneka

Ukukhanyisa kuyisigaba sokuqala se-cavitation.Kodwa-ke, kungenzeka ukuthi ukukhanya kuzenzele ngokwakho ngaphandle kokwenzeka kwe-cavitation.
Ukubaneka kwenzeka ekugelezeni koketshezi lapho olunye uketshezi lushintsha unomphela lube umhwamuko.Lokhu kubangelwa ukuncipha kokucindezela okuphoqa uketshezi ukuthi lushintshele esimweni segesi.Ukuncipha kokucindezela kubangelwa ukuvinjelwa kumfudlana ogelezayo okhiqiza izinga lokugeleza eliphakeme ngomkhawulo futhi ngenxa yalokho nokuncipha kwengcindezi.
Izinkinga ezimbili eziyinhloko ezibangelwa ukukhanyisa yilezi:

– Ukuguguleka
– Umthamo owehlisiwe

Ukuguguleka komhlabathi

Lapho ukukhanya kwenzeka, ukugeleza okuvela endaweni yokuphuma kwe-valve kwakhiwa uketshezi kanye nomhwamuko.Ngokubaneka okwandisiwe, umhwamuko uthwala uketshezi.Njengoba isivinini sokugeleza sikhuphuka, uketshezi lusebenza njengezinhlayiya eziqinile njengoba lushaya izingxenye zangaphakathi zevalvu.Isivinini sokugeleza kokuphuma singancishiswa ngokwandisa usayizi we-valve okunganciphisa umonakalo.Izinketho zokusebenzisa izinto eziqinile zingesinye isixazululo.Ama-engeli ama-engeli alungele lolu hlelo lokusebenza njengoba ukukhanya kwenzeka ngokuqhubekayo phansi nomfula kude nokuhlanganiswa kwe-trim nama-valve.

Amandla Ancishisiwe

Lapho umfudlana ogelezayo ngokwengxenye ushintsha ube umhwamuko, njengasesimweni sokubaneka, isikhala osithathayo siyakhula.Ngenxa yendawo etholakalayo encishisiwe, amandla e-valve yokusingatha ukugeleza okukhulu anqunyelwe.Ukugeleza okuminyanisiwe igama elisetshenziswa lapho umthamo wokugeleza ulinganiselwe ngale ndlela

I-Cavitation

I-Cavitation iyafana nokubanika ngaphandle kokuthi ingcindezi itholwa ku-outlet flowstream kangangokuthi umhwamuko ubuyiselwa oketshezini.Umfutho obalulekile wumfutho womhwamuko woketshezi.Ukucwayiza kwenzeka ngezansi nje kwe-valve trim lapho ingcindezi yehla ngaphansi komfutho womhwamuko, bese amabhamuza ewa lapho umfutho ubuya ngaphezu komfutho womhwamuko.Lapho amabhamuza egoqa, athumela amagagasi amakhulu okwethuka emfudlaneni ogelezayo.Ukukhathazeka okuyinhloko nge-cavitation, ukulimala kwe-trim nomzimba we-valve.Lokhu kubangelwa ngokuyinhloko ukugoqa kwamabhamuza.Kuye ngezinga le-cavitation eyakhiwe, imiphumela yayo ingaba kusuka ku-a
umsindo oheyizayo opholile onomonakalo omncane noma ongekho nhlobo ekufakweni okunomsindo omkhulu okubangela ukulimala okukhulu ngokomzimba ku-valve kanye namapayipi angezansi komfula I-cavitation eqinile inomsindo futhi ingazwakala sengathi amatshe ageleza kuvalvu.
Umsindo okhiqizwayo awuyona into ekhathaza kakhulu ngokombono wokuphepha komuntu siqu, njengoba ngokuvamile uphansi ngobuningi kanye nomfutho futhi ngenxa yalokho awudali inkinga kubasebenzi.
