Hydraustatic kuaj:
Cov yeeb nkab steel yuav tsum tau sim ua kom hydraulicically ib qho los ntawm ib qho. Qhov ntsuas qhov siab tshaj plaws yog 20 MPA. Nyob rau hauv qhov kev ntsuas siab, lub sijhawm ua tiav yuav tsum tsis pub tsawg tshaj 10 s, thiab cov yeeb nkab steel yuav tsum tsis txhob xau. Lossis cov kev kuaj mob hydraulic tuaj yeem hloov los ntawm Eddy kev sim tam sim no lossis sib nqus flux xau.
Nondestructive Test:
Cov kav dej uas yuav tsum tau kuaj xyuas ntau dua yuav tsum yog qhov ntsuas hluav taws xob ultrasonically ib qho los ntawm ib qho. Tom qab cov kev sib tham xav tau kev pom zoo los ntawm tog neeg thiab yog teev nyob rau hauv daim ntawv cog lus, lwm yam kev sim tsis yog kev ua kom tsis yog kev puas tsuaj tuaj yeem ntxiv.
Kaj ntsuam xyuas:
Tubes nrog ib txoj kab sab nraud loj dua 22 hli yuav raug rau kev ntsuas siab dav. Tsis pom kev txiav txim siab, dawb me me, lossis cov impurities yuav tsum tshwm sim thaum txhua qhov kev sim.
Kuaj Hardness:
Rau cov yeeb nkab ntawm qib P91, P122, P122, thiab P911, Brinell, vickang, vickang, vickwell kev ntsuam xyuas yuav tsum tau ua rau ib qho hnoos qeev los ntawm txhua yam
