Tijaabada Hydrostatic
Tuubo u adkeysan karta tijaabada hydrostatic iyada oo aan laga daadan tolmada alxanka ama jirka tuubada. Isku-xidhayaasha looma baahna in la tijaabiyo hydrostatic haddii qaybaha tuubooyinka la isticmaalay si guul leh loo tijaabiyay.
Imtixaanka laabista
Qayb kasta oo ka mid ah qaybta tijaabada ah kama dhici doonto dildilaac, mana jiri doonto furitaan alxanka ah.
Tijaabada fidsanaanta
Shuruudaha aqbalaadda ee tijaabada siman waa inay ahaadaan:
- Tuubooyinka EW D <12.750 gudaha:
- X60 oo leh T 500in. Ma jiri doonto furitaan alxanka ka hor inta masaafada u dhaxaysa taarikada aysan ka yarayn 66% dhexroorka dibadda ee asalka ah. Dhammaan darajooyinka iyo darbiga, 50%.
- Tuubada leh D/t > 10, ma jiri doonto furitaan alxanka ka hor inta masaafada u dhaxaysa saxanadaha aysan ka yarayn 30% dhexroorka dibadda ee asalka ah.
- Cabbirrada kale, tixraac dhammaanAPI 5Lqeexitaan.
Tijaabada saameynta CVN ee PSL2
Cabbirro iyo darajooyin badan oo tuubooyinka PSL2 ah ayaa u baahan CVN. Tuubo aan tolnayn ayaa lagu tijaabinayaa jirka. Tuubada alxanka leh waa in lagu tijaabiyaa jirka, alxanka tuubooyinka iyo aagga uu kulaylka saameeyay. Ka eeg dhammaanAPI 5Lqeexitaan jaantuska cabbirrada iyo darajooyinka iyo qiimayaasha tamarta la nuugo ee loo baahan yahay.
