Folasaga
1. Ina ia faʻateleina le ola galue o le pusa piston pe a viliina maʻa sili ona abrasive, o le avetaʻavale sub ua fuafuaina e faia i luga o le tolu vaega ma na o le ofuina-faamaonia casing e tatau ona suia i le taimi.
2. O le piston fa'afefeteina ma le fa'aogaina o le pa'u i totonu o lo'o fa'atulagaina lelei ina ia ausia le maualuga maualuga ma le malosi sili ona a'afia.O le saoasaoa o le faʻaogaina o le 10% -30% vave nai lo isi oloa o le ituaiga tutusa.
3. E itiiti pu ea i luga o le pa'u i totonu, maualuga Malosi o le ea slot.
4. O le tele o filo o loʻo faʻapipiʻiina le CNC e ausia ai le maualuga maualuga, faʻafaigofie ma lamolemole le faʻapipiʻiina.Avetaavale sub e togafitia vevela ina ia maua ai le abrasiveness sili atu ma umi le ola.
5. Samala mamanu fausaga pito i luma: pe a toso ese le samala, o le aafiaga mulimuli o le piston o le a pau i luga o le laasaga o le pusa piston, faʻamautinoa le saogalemu o le avetaʻavale i lalo spline oneone le mama taofi.
6. Piston case: Faʻaaogaina o le sila uamea sili, e sili atu le faʻatuatuaina ma le umi o le ola pe a uma togafitiga vevela.
7. O vaega i totonu o loʻo faʻapipiʻiina lelei ina ia aloese mai le ofuina o fefaʻatauaʻiga ma faʻateleina le faʻatuatuaina o le samala.
8. Fa'asologa API filo.
