Kev Ntsuas Hydraustic:
Cov Yeeb Nkab Hlau Yuav Tsum Tau Sim Hydraulically Ib Qho Los Ntawm Ib Qho. Qhov Siab Tshaj Plaws Kev Ntsuas Yog 20 MPa. Nyob rau hauv Qhov Siab Kev Ntsuas, Lub Sijhawm Ruaj Khoov Yuav Tsum Tsis Tsawg Dua 10 S, Thiab Cov Yeeb Nkab Hlau Yuav Tsum Tsis Tawg. Lossis Qhov Kev Ntsuas Hydraulic tuaj yeem hloov los ntawm Eddy Current Kev Ntsuas Lossis Magnetic Flux Leakage Kev Ntsuas.
Kev Ntsuas Tsis Ua Phem:
Cov kav dej uas xav tau kev tshuaj xyuas ntau dua yuav tsum tau tshuaj xyuas ultrasonic ib zaug ib zaug. Tom qab kev sib tham yuav tsum tau kev pom zoo ntawm tog neeg thiab tau teev tseg hauv daim ntawv cog lus, lwm yam kev sim tsis ua puas tsuaj tuaj yeem ntxiv tau.
Kev Ntsuas Flattening:
Cov raj uas muaj txoj kab uas hla sab nraud loj dua 22 hli yuav tsum raug kuaj kom tiaj. Yuav tsum tsis txhob muaj qhov tawg, cov pob dawb, lossis cov khoom tsis huv tshwm sim thaum lub sijhawm sim tag nrho.
Kev Ntsuas Qhov Nyuaj:
Rau Cov Yeeb Nkab Qib P91, P92, P122, Thiab P911, Brinell, Vickers, Los Yog Rockwell Hardness Tests Yuav Tsum Ua Rau Ib Qho Qauv Los Ntawm Txhua Qhov
