Test Chinodiwa

Hydraustatic Test:

Iyo pombi yesimbi inofanirwa kuongororwa hydraulically imwe neimwe. Iyo yakanyanya test pressure ndeye 20 MPa. Pasi pekumanikidzwa kwekuedza, nguva yekudzikamisa inofanira kunge isiri pasi pe10 s, uye pombi yesimbi haifaniri kudonha.

Mushure mekunge mushandisi abvuma, iyo hydraulic bvunzo inogona kutsiviwa needdy yazvino kuyedza kana magineti flux kuvuza kuyedzwa.

Nondestructive Test:

Mapaipi anoda kuongororwa zvakanyanya anofanirwa kuongororwa ultrasonically imwe neimwe. Mushure mokunge nhaurirano inoda kubvumirwa kwebato uye inotsanangurwa muchibvumirano, kumwe kuedza kusina kuparadza kunogona kuwedzerwa.

Flattening Test:

Machubhu ane dhayamita rekunze rakakura kudarika 22 mm achaiswa muyedzo yekubata bata. Hapana delamination inooneka, mavara machena, kana tsvina inofanirwa kuitika panguva yese yekuyedza.

Flaring Test:

Zvinoenderana nezvinodiwa nemutengi uye zvakataurwa muchibvumirano, pombi yesimbi ine dhayamita yekunze ≤76mm uye ukobvu hwemadziro ≤8mm inogona kuitwa flaring test . Kuedza kwakaitwa pakamuri tembiricha ine taper ye60 °. Mushure mekupisa, mwero wekupisa wedhayamita yekunze unofanirwa kusangana nezvinodiwa zvetafura inotevera, uye zvinhu zvekuyedza hazvifanirwe kuratidza kutsemuka kana kubvaruka.
