Shuruudaha Imtixaanka

Baaritaanka Hydrostatic

Dhuumaha si ay ugu adkeystaan baarista hydrostatic iyada oo aan laga daadan tolleynta alxanka ama jirka tuubada. Isku-xirayaashu uma baahna in la tijaabiyo biyo-staatig ah haddii qaybaha tuubooyinka la isticmaalo si guul leh loo tijaabiyey.

Tijaabada laablaab

Wax dildilaac ahi waa inuu ka dhacaa qayb ka mid ah qaybta tijaabada, alxankana ma dhici doono.

Tijaabada fidsan

Shuruudaha oggolaanshaha ee tijaabada sabbaynta waa inay ahaadaan:

Tuubooyinka EW D<12.750 gudaha:
X60 oo leh T500in. Waa in aan la furin alxanka ka hor inta masaafada u dhaxaysa taarikada ay ka yarayn 66% dhexroorka dibadda ee asalka ah. Dhammaan darajooyinka iyo darbiga, 50%.
Tuubbada leh D/t> 10, waa in aan la furin alxanka ka hor inta masaafada u dhaxaysa taarikada aysan ka yarayn 30% dhexroorka dibadda ee asalka ah.
Cabbirrada kale tixraac buuxaAPI 5Lqeexid.

Tijaabada saamaynta CVN ee PSL2

Cabbirrada tuubooyinka PSL2 iyo darajooyin badan ayaa u baahan CVN. Dhuumaha aan xumaanta lahayn waa in lagu tijaabiyaa jirka. Dhuumaha alxanka leh waa in lagu tijaabiyaa jirka, alxanka tuubada iyo aagga uu kuleylku saameeyay. Tixraac buuxaAPI 5Lqeexidda jaantuska cabbirrada iyo darajooyinka iyo qiimaha tamarta la nuugo ee loo baahan yahay.
