Fa'atekonolosi Valve Choke ma le Fa'aogaina o Alloys Malosi i Valves Choke
Fa'atekonolosi Valve Choke ma le Fa'aogaina o Alloys Malosi i Valves Choke
O va'a latina o vaega taua ia i faiga e pulea ai le suavai mo le suau'u, kesi, ma fale kemikolo, e fa'aaogaina e fa'atonu tonu ai le tafe, fa'amautu le mamafa, ma puipuia ai le cavitation ma le tafia. I lalo o tulaga ogaoga faʻaogaina (maualuga maualuga, pala, faʻasolosolo faʻasolosolo), mea masani masani e masani ona le ausia manaʻoga umi. Alu malō, e pei o le tungsten carbide (WC), faʻatasi ai ma lo latou malosi maualuga, faʻafefeteina, ma le faʻamaʻiina o le pala, ua avea ma filifiliga sili mo vaega autu o le valve valve. O lenei tusiga o loʻo suʻesuʻeina mataupu faʻavae o vaʻavaʻa latina, faiga masani faʻaletonu, ma taulaʻi i le lelei o uʻamea malo i faʻauʻu valve, nofoa, ma faʻamaufaʻailoga.
1. Galuega Autu ma Lu'itau o Valve Laisa
1.1 Galuega a Valve Laisa
Tulafono Fa'atonu: Pulea le mamafa o le ulu lelei e puipuia ai le gaosiga o le oneone po'o le sasaina ona o le pa'u fa'afuase'i o le mamafa.
Pulea o le tafe: Fetuuna'i fua faatatau o le gaosiga o le hydrocarbon ina ia fetaui ma le gafatia o le gaosiga i lalo.
