Isetyenziselwa ukwenza amacandelo abalulekileyo koomatshini abahlukeneyo abanempembelelo, ukugoba kunye ne-torsion kunye nomthwalo ophezulu, njengegiya ye-herringbone, i-crankshaft, intonga yesando, intonga yokudibanisa kunye ne-fasteners ye-steel rolling mill, i-shaft engundoqo kunye ne-axle ye-injini ye-injini yomphunga, ukuhanjiswa kwe-injini. iindawo, ishafti enkulu yemoto, iperforator koomatshini bepetroleum, iibholiti zebhoyila ezinobushushu bokusebenza obungaphantsi kwe-400 ℃, amandongomane anobushushu bokusebenza obungaphantsi kwe-510 ℃, Uxinzelelo oluphezulu olungenamthungo lomsele wodonga olungqingqwa (ubushushu 450 ~ 500 ℃, akukho nkunkuma eyingozi) koomatshini bekhemikhali. ; Inokuthi ithathe indawo ye-40crni yokuvelisa ishaft yokuhambisa umthwalo ophezulu, i-rotor ye-injini ye-steam, i-gear yecandelo elikhulu, i-shaft yenkxaso (ububanzi obungaphantsi kwe-500mm), njl. Izinto zokusebenza zenkqubo, imibhobho, izinto ze-welding, njl.
Isetyenziswe njengeendawo ezibalulekileyo zesakhiwo ezisebenza phantsi komthwalo ophezulu, njengeendawo zokuhambisa izithuthi kunye neenjini; I-Rotor, ishaft engundoqo, ishaft yokuhambisa umthwalo onzima kunye necandelo elikhulu lejenereyitha ye-injini yomphunga.
