Intshayelelo
Isandi senziwa ngokushukuma kolwelo ngevalvu.Kuphela kuxa isandi esingathandekiyo sibizwa ngokuba 'yingxolo'.Ukuba ingxolo ingaphezulu kwamanqanaba athile oko kunokuba yingozi kubasebenzi.Ingxolo ikwasisixhobo esilungileyo sokuxilonga.Njengoko isandi okanye ingxolo yenziwa kukungqubana, ingxolo egqithisileyo ibonisa umonakalo onokwenzeka ngaphakathi kwevalve.Umonakalo unokubangelwa yi-friction ngokwayo okanye i-vibration.
Mithathu imithombo ephambili yengxolo:
-Ukungcangcazela koomatshini
-Ingxolo yeHydrodynamic
-Ingxolo yeAerodynamic
Ukungcangcazela koomatshini
Ukungcangcazela komatshini kuluphawu oluhle lokuwohloka kwamalungu evalvu.Ngenxa yokuba ingxolo eyenziwayo iqhele ukuba namandla kwaye iphantsi, ayiyongxaki yokhuseleko kubasebenzi.Ukungcangcazela kuyingxaki ngakumbi ngeevalvu zesikhondo xa kuthelekiswa neevalvu zekheji.Iivalvu zekheji zinendawo enkulu yokuxhasa kwaye ngoko ke azifane zibangele iingxaki zokungcangcazela.
Ingxolo yeHydrodynamic
Ingxolo ye-Hydrodynamic iveliswa kumanzi aqukuqelayo.Xa ulwelo ludlula kwisithintelo kwaye utshintsho loxinzelelo lwenzeka kunokwenzeka ukuba ulwelo lwenze amaqamza omphunga.Oku kubizwa ngokudanyaza.I-Cavitation nayo yingxaki, apho i-bubbles ifom kodwa emva koko iwa.Ingxolo eyenziwayo ayiyongozi kubasebenzi, kodwa luphawu oluhle
yomonakalo onokubakho kumacandelo okunquma.
Ingxolo yeAerodynamic
Ingxolo yeAerodynamic iveliswa kukuphazamiseka kweegesi kwaye ngowona mthombo wengxolo.Amanqanaba engxolo eyenziwayo anokuba yingozi kubasebenzi, kwaye axhomekeke kumthamo wokuhamba kunye nokuhla koxinzelelo.
Cavitation kunye Ukudanyaza
Ukudanyaza
Ukukhanyisa yinqanaba lokuqala le-cavitation.Nangona kunjalo, kuyenzeka ukuba idanyaze izenzekele ngokwayo ngaphandle kwe-cavitation eyenzekayo.
Ukudanyaza kwenzeka kumpompozo wolwelo xa olunye ulwelo lutshintsha ngokusisigxina lube ngumphunga.Oku kuziswa kukuncipha koxinzelelo olunyanzelisa ulwelo ukuba lutshintshe kwisimo segesi.Ukunciphisa uxinzelelo kubangelwa ukuthintela kwi-flowstream okuvelisa izinga eliphezulu lokuhamba ngokukhawulela kwaye ngoko ke ukunciphisa uxinzelelo.
Iingxaki ezimbini eziphambili ezibangwa ngokudanyaza zezi:
– Ukhukuliseko
– Ukucutha umthamo
Ukhukuliseko
Xa kudanyaza kwenzeka, ukuhamba okuphuma kwindawo yokuphuma kwevalve kwenziwa ngolwelo kunye nomphunga.Ngokudanyaza okwandileyo, umphunga uthwala ulwelo.Njengoko isantya sokuhamba sisanda, ulwelo lusebenza njengamasuntswana aqinileyo njengoko lubetha iindawo zangaphakathi zevalve.Isantya sombhobho wokuphuma singancitshiswa ngokunyusa ubungakanani bevalvu yokukhupha into enokunciphisa umonakalo.Ukhetho lokusebenzisa izinto ezilukhuni sesinye isisombululo.Iivalvu ze-engile zisifanelekele esi sicelo njengoko idanyaza isenzeka ezantsi komjelo kude ne-trim kunye ne-valve assembly.
Isakhono esiNcitshisiweyo
Xa umsinga ohambayo utshintsha ngokuyinxenye ube ngumphunga, njengakwimeko yokudanyaza, isithuba esihlala kuso siye sandiswa.Ngenxa yokunciphisa indawo ekhoyo, umthamo wevalve yokusingatha ukuhamba okukhulu ulinganiselwe.Ukuqukuqela okuminxekileyo ligama elisetyenziswayo xa umthamo wokuqukuqela ulinganiselwe ngale ndlela
Cavitation
I-Cavitation iyafana nokudanyaza ngaphandle kokuba uxinzelelo lubuyiselwa kwi-outlet flowstream ukwenzela ukuba umphunga ubuyiselwe kumanzi.Uxinzelelo olubalulekileyo luxinzelelo lomphunga wolwelo.Ukudanyaza kwenzeka kanye ezantsi komjelo wevalvu yokutrima xa uxinzelelo lwehla ngaphantsi koxinzelelo lomphunga, kwaye amaqamza ayawa xa uxinzelelo lubuyela ngaphezulu koxinzelelo lomphunga.Xa amaqamza esihla, athumela amaza othusayo kakhulu kumsinga ohambayo.Inkxalabo ephambili nge-cavitation, ngumonakalo kwi-trim kunye nomzimba we-valve.Oku kubangelwa ikakhulu kukudilika kwamaqamza.Ngokuxhomekeke kubungakanani be-cavitation ephuhlisiwe, iziphumo zayo zinokuvela kwi-a
isandi sokufutha esithambileyo esinomonakalo omncinci okanye akukho sisixhobo sofakelo olunengxolo ephezulu ebangela umonakalo omkhulu womzimba kwivalve kunye nemibhobho ephantsi komlambo I-Cavitation ebukhali iyangxola kwaye inokuvakala ngathi igrabile iqukuqela kwivalve.
Ingxolo eveliswayo ayiyonto ixhalabisa kakhulu ngokwembono yokhuseleko lomntu, njengoko ihlala iphantsi ngamaza omoya kunye nokuqina kwaye ayibeki ngxaki kubasebenzi.
