Calu ma dwand copo bedu ku adwogi marac ikum kum dhanu, frequency moko copo nyayu peko ikum jam tic mi tic ka control valve juyeru maber, etiye ku peko madit mi cavitation, ma copo kelo dwand ma lee man yeng yeng, ma copo kelo ret ma nyai ikum paip ma iye man ma piny pa piivalve.
Mi medo, dwand ma tek pol kare nyayu yeng yeng ma copo nyotho paip, jam tic man jam tic mukendeValveku kadho pa kare, nyoth pa piny, valve cavitation ma wok kud i pipeline system ma copo nyayu peko madit. Peko eni wok ikum tego pa dwand yeng yeng, tic mi nyai man cavitation ma wok kud i dwand ma malu pa yeng yeng ma dit ma wok kud i yik man podho pa steam bubbles ceng man piny pa shrinkage.
Kadok eni pol kare timere i mupiravalvesman rotary valves i kum, ecopu timere i kare manok, ma malu ma rom ku wafer body part pa V-ballvalve, mandha nebutterfly valvesI thenge ma piny pa valve kavalveutiye i kabedo acel ma nyayu cavitation phenomenon, ma nyayu leakage i valve piping man welding repair, valve epe pi thenge eni mi line.
Kadi bed ni cavitation timere i kind valve nyo piny pa valve, jam tic i kabedo mi cavitation bibedo ku peko madit ikum ultra-thin films, springs man small section cantilever structures, vibrations madongo copo nyayu oscillations. Kabedo ma rwinyo nwangire i jam tic macalo pressure gauges, transmitters, thermocouple sleeves, flowmeters, sampling systems Actuators, positioners man limit switches ma tye ku springs bibedo ku peko mi rwinyo, man mounting brackets, fasteners man connectors bibedo ma rwinyo man rwinyo pi yeng yeng.
Fretting corrosion, ma timere ikind piny ma rwinyo ma wok ku yeng yeng, utiye piny ma timire inget cavitation valves. Eni wodhu oxides matek calu abrasives mi medo nyai pa piny ma nyai. Jam tic ma nyayu peko uketho i iye isolation man check valves, man control valves, pumps, rotating screens, samplers man rotating nyo sliding mechanism mange.
Yeng yeng ma tek copo turo man nyayu ret ikum jam valve man kor ot pa paip. Jam piny ma nyai nyoke kemikol ma nyai copo nyayu two i paip, ma copo bedu ku adwogi marac ikum pii ma leng man pii ma leng. Eni de juyiyu ngo.
Lembe ma jular jukoro ikum cavitation failure pa plug valves utiye lembe ma nyang ikume man epe ikum choke pressure drop kende. Lembe ma dhanu ukadhu kud i iye nyutho nya ecopu bedu nya tegu pa pii ma mol udok piny ni tegu pa pii ma pii ma pii pii ma podi epodho ngo i kabedu ne man podho pa pii ma pii pii. Jumoko ma yiku valve giwacu nia eclipse copo wok ma podi kare pare rwinyo ungo ni kadhu kud i dwoko piny pa pressure mi ret. Yore pa ju ma yiku valve mi caku ku paru pa cavitation ucungo iwi lembe ma nia steam bubbles upodhu, ma kelo cavitation man koko. Junwango nia peko madit mi cavitation jubi jwigo ka rwom pa dwand ma ju kwanu utiye piny pa rwom ma jugoro piny eno.
Dit pa valve ma romo inci 3 – 80 dB
Dit pa valve pa 4-6 inches – 85 dB
Dit pa valve 8-14 inches – 90 dB
Dit pa valve pa 16 inches man malac – 95 dB
Yore mi daru peko pa cavitation
Yub pa valve ma pire tek mi jwigo cavitation tiyo ku split flow man graded pressure drop:
"Valve diversion" utiye poko pii madit i pii ma nok nok, man yore mi mol pa valve juyike kara pii ucidh ikind kabedo ma nok ma nok. Calu dul pa dit pa bubble mi cavitation ju kwanu kud i dhugola ma pii kadhu kud i iye. Kabedo ma nok ma oyabere miyo pii ma nok bedo nuti, ma kelo koko manok man nyayu peko manok ka bino i peko.
"Graded pressure drop" nyutho nia valve juyike ni bedu ku kabedu ario nyo madwong ma juyike i rwom acel, ento kakare ni dwoko piny ceke i rwom acel, etingo rwom ma nok nok. Piny ma nok pa rwom pa rwom acel acel ecopu juku rwom pa rwom ma piny kud i rwom ma piny pa rwom pa pii, ma copo jwigo peko mi cavitation i valve.
Dikiri pa loko man dwoko piny pa pressure i valve acel weko cavitation bedo maber. I kare mi loko valve, ketho valve mi tela man kero i dhugola mi valve ubedo malo (calu ve yo malu, nyo i bor ma piny), saa moko jwigo peko mi cavitation.
Mi medo, ketho valve mi tela kama lyethu pa pii utiye iye, man kumeno rwom ma piny pa pii (macalu lyethu ma piny) ecopu konyo ni jwigo peko mi cavitation.
Lembe ma jugoro unyutho nia cavitation phenomenon pa valves epe kende ikum tic pa valves man nyayu ret pa valves. Pipelines man jam tic ma piny de utiye i ariti. Nyuthu cavitation man timo lembe mi jwigo ubedo yore acel kende mi jwigo peko mi tiyo ku valve ma tek.
