Indawo yosetyenziso
Isetyenziselwa kakhulu ukugqiba ukusebenza kwe-creep kunye namandla okunyamezela kwezixhobo zetsimbi phantsi kobushushu obuthile kunye nomthwalo oqhubekayo ngaphakathi kwexesha elithile.
Ukuphumeza umgangatho oqhelekileyo we-GB / T2039-1997 "I-Metal Tensile Creep kunye ne-Endurance Test Method", i-JJG276-88 "iMimiselo yoQinisekiso kwi-High Temperature Creep kunye ne-Endurance Strength Testing Machine".
Ezona mpawu
Inkcazo esemgangathweni yobushushu obuphezulu kunye nomatshini wokuvavanya amandla okunyamezela isetyenziselwa ukumisela ukunyuka kobushushu obuphezulu kunye nokusebenza kwamandla okunyamezela kwezixhobo zetsimbi phantsi kweemeko zobushushu obungaguqukiyo kunye nokunyanzeliswa kwamandla aqhubekayo kwicala le-axial yesampuli.
Iimpawu zobuGcisa
Qwalasela izincedisi ezihambelanayo ukufikelela:
(1) Uvavanyo lwamandla okunyamezela ubushushu obuphezulu:
A. Ixhotyiswe ngesixhobo sovavanyo lobushushu obuphezulu kunye nenkqubo yokulawula ubushushu,
B. Ixhotyiswe ngentonga yokutsala esisigxina (i-specimen clamp),
C. Amandla ahlala ezinto eziphathekayo angalinganiswa phantsi kwesenzo sokushisa rhoqo kunye nomthwalo oqhubekayo.
(2) Uvavanyo oluphezulu lobushushu:
A, ixhotyiswe ngesixhobo sovavanyo lobushushu obuphezulu kunye nenkqubo yokulawula ubushushu,
B, ixhotyiswe ngobushushu obuphezulu bokurhubuluza intonga (isampulu yesampulu)
C, ixhotyiswe nge-creep extensometer (isixhobo sokuzoba ideformation)
D, ixhotyiswe ngesixhobo sokulinganisa esirhubuluzayo (isixhobo sokulinganisa i-deformation).
Iipropati ze-creep zezinto eziphathekayo zinokulinganiswa phantsi kobushushu obuqhubekayo kunye nomthwalo oqhubekayo wokunyuka.
