Ii-Shaft Forgings ze-Hydraulic turbines kunye ne-Hydraulic Generators

1 Ukunyibilika

1.1 Ukunyibilikiswa kwesithando sombane esinealkali kufuneka kusetyenziswe ukwenza intsimbi.

2 Ukubumba

2.1 Isibonelelo esaneleyo sokusika kufuneka sibe khona kwiindawo eziphezulu kunye nezisezantsi ze-ingot yensimbi ukuze kuqinisekiswe ukuba isiqwenga esibunjiweyo sikhululekile kwi-shrinkage cavities kunye nokwahlula okunzima.

2.2 Isixhobo soku forging kufuneka sibe nomthamo owaneleyo wokuqinisekisa ukufogina ngokupheleleyo kulo lonke icandelo. Ubume kunye nobukhulu beqhekeza elibunjiweyo kufuneka lihambelane ngokusondeleyo neemfuno zemveliso egqityiweyo. I-axis yeqhekeza elibunjiweyo kufuneka ilungelelanise ngokufanelekileyo kunye ne-centerline ye-ingot yensimbi.

3 Unyango lobushushu

3.1 Emva kokuba i-forging, iqhekeza elibunjiweyo kufuneka liqhube unyango oluqhelekileyo kunye nokufudumala, kwaye ukuba kuyimfuneko, ukucinywa kunye nokunyangwa kokunyanga ukufumana isakhiwo esifanayo kunye neepropati.

4 Ukuwelda

4.1 I-axial welding enkulu kufuneka iqhutywe emva kokuba uvavanyo lwentsebenzo yomatshini yeqhekeza elibunjiweyo lihlangabezana neemfuno. I-electrodes ye-welding eneepropathi ezilinganayo zomatshini kwiqhekeza elibunjiweyo kufuneka lisetyenziswe, kunye nezona nkcukacha ze-welding kufuneka zikhethwe kwinkqubo ye-welding.

5 IiMfuno zobuGcisa

5.1 Uhlalutyo lwekhemikhali kufuneka luqhutywe kwibhetshi nganye yensimbi etyhidiweyo, kwaye iziphumo zokuhlalutya kufuneka zihambelane neenkcukacha ezifanelekileyo.

5.2 Emva kokunyanga ubushushu, iimpawu ze-axial mechanical yeqhekeza elibunjiweyo kufuneka lihlangabezane neenkcukacha ezifanelekileyo. Ukuba umthengi ufuna, iimvavanyo ezongezelelweyo ezifana nokugoba okubandayo, ukucheba, kunye nobushushu benguqu ye-nil-ductility inokwenziwa.

5.3 Umphezulu weqhekeza elibunjiweyo kufuneka lingabikho kwiintanda ezibonakalayo, ukugoba, kunye nezinye iziphene ezibonakalayo ezichaphazela ukusetyenziswa kwayo. Iziphene zendawo zingasuswa, kodwa ubunzulu bokususwa akufanele budlule i-75% yesibonelelo somatshini.

5.4 Umngxuma ophakathi weqhekeza elibunjiweyo kufuneka uhlolwe ngokubonakalayo okanye usebenzisa i-boroscope, kwaye iziphumo zokuhlola kufuneka zihambelane neenkcukacha ezifanelekileyo.

5.5 Uvavanyo lwe-Ultrasonic kufuneka lwenziwe kumzimba kunye ne-welds yeqhekeza elibunjiweyo.

I-5.6 Ukuhlolwa kweengqungquthela zamagnetic kufuneka kuqhutywe kwisiqwenga esibunjiweyo emva kokulungiswa kokugqibela, kunye neendlela zokumkela kufuneka zihambelane neenkcukacha ezifanelekileyo.
