Yiziphi izindlela zokwelapha ukushisaipayipi lensimbi eliqondile lomthungo?
Okokuqala, ukwakheka kwesakhiwo sokubunjwa kwezobuchwepheshe kufanele kube okunengqondo, ukujiya akufanele kuhluke kakhulu, futhi umumo kufanele ube symmetrical. Ukuze uthole isikhunta esine-deformation enkulu, imithetho ye-deformation kufanele ibanjwe, futhi imvume yomshini kufanele igcinwe. Ezikhunjini ezinkulu, ezinhle nezingahlelekile, ukwakheka okuhlanganisiwe kungakhethwa. Kwezinye isikhunta esihle nesiphazamisekile, ukwelashwa ngaphambi kokushisa, ukwelashwa kokushisa okuguga kanye nokwelashwa kokushisa kwe-nitriding okuncishisiwe kungakhethwa ukuze kulawulwe ukunemba kwesikhunta. Lapho kulungiswa iziphambeko ezifana nomgodi wesihlabathi, imbobo yomoya kanye nokugqoka kwesikhunta, imishini yokulungisa enomthelela omncane oshisayo njengomshini we-welding obandayo uzokhethwa ukugwema ukuguqulwa ngesikhathi sokulungiswa.
Izibungu ezinhle nezingahlelekile kufanele ziphathwe ngaphambi kokushisa ukuze kuqedwe ingcindezi esele ngesikhathi somshini. Ngesikhunta esihle nesiphazamisekile, ukucisha ukushisisa ngevacuum kanye nokwelashwa kokupholisa okujulile ngemva kokucisha kuzokhethwa ngokusemandleni uma izimo zivuma. Ngokwesisekelo sokuqinisekisa ukuqina kwesikhunta, ukupholisa kwangaphambili, ukucisha ukupholisa ngesiteji noma inqubo yokucisha okufudumele kuyokhethwa ngokusemandleni.
Khetha izinto ngokunengqondo. Ngokufa okuhle nokungahlelekile, i-micro deformation die steel enezinto ezinhle zokusetshenziswa izokhethwa. Insimbi edayiyo enokwehlukaniswa kwe-carbide okunzima izophonswa kahle futhi ibhekane nokwelashwa kokucisha nokushisa. Ngensimbi enkulu nengeyona i-cast, isixazululo esiqinile sokushisa okuphindwe kabili singenziwa. Khetha ngokufanelekile izinga lokushisa lokushisa futhi ulawule isivinini sokushisisa. Ezikhunjini ezinhle nezingahlelekile, ukushisisa kancane, ukushisa kwangaphambi kwesikhathi nezinye izindlela zokushisisa ezilinganiselayo zingamukelwa ukuze kuncishiswe ukuwohloka kokwelashwa kokushisa kwesikhunta.
I-JCOE iwubuchwepheshe bokwenza ipayipi ukuze kukhiqizwe amapayipi amakhulu ensimbi odongeni ububanzi obukhulu. Yamukela ikakhulukazi inqubo yokukhiqiza yokushisela i-arc engaphansi kwezinhlangothi ezimbili. Imikhiqizo ihamba ngezinqubo eziningi ezifana nokugaya, ukugoba ngaphambili, ukugoba, ukuvala umthungo, ukushisela kwangaphakathi, ukushisela kwangaphandle, ukuqondisa, kanye nesiphetho esiyisicaba. Inqubo yokwenza ingahlukaniswa ngezinyathelo ezingu-N+1 (N iyinamba ephozithivu). Ipuleti lensimbi liphakelwa ngokuzenzakalelayo eceleni futhi ligotshwe ngokuya ngosayizi wesinyathelo esibekiwe ukuze kubonwe ukulawulwa kwezinombolo okuqhubekayo kwe-JCO. Ipuleti lensimbi lingena emshinini wokwakha ngokuvundlile, futhi ngaphansi kokusunduzwa kwetroli yokudla, isigaba sokuqala sokugoba ngezinyathelo eziningi ngezinyathelo ze-N/2 senziwa ukuze kubonwe ukwakheka kuka-"J" kwengxenye yangaphambili yepuleti lensimbi; Esigabeni sesibili, okokuqala, ipuleti lensimbi elakhiwe ngu-"J" lizothunyelwa endaweni ecacisiwe endaweni eguquguqukayo ngokushesha, bese ipuleti lensimbi elingashintshiwe ligotshwe ngezinyathelo eziningi ze-N/2 ukusuka komunye umkhawulo ukuze libone. ukwakhiwa kwesigamu sesibili sepuleti yensimbi bese uqedela ukwakheka "C"; Ekugcineni, ingxenye engezansi ye-"C" yohlobo lweshubhu engenalutho igotshwa kanye ukuze kubonakale ukwakheka kuka-"O". Umgomo oyisisekelo wesinyathelo ngasinye sokugxiviza ukugoba ngamaphuzu amathathu.
