Mona re thathamisitse haholo-holo maemo a ka tlase a 3 a robehileng-Bush Broken kapa Rod Eye Roken kapa tse ling tsa Mount Connection Failure;Rod Weld e robehile mme Rod e robehile.
1. Sehlahla se Robehile, Leihlo la Lere le Robehile,kapa ho Hloleha ha Mount Connection tse ling
Silinda e kenngoa ka mekhoa e fapaneng: mahlo a molamu kapa barrel, trunnion, flange, le tse ling.Ha cylinder e tletse kapa e sa tsamaisane hantle, khatello e feteletseng e sebelisoa ho khokahanyo e ntseng e phahama e fellang ka ho apara ka potlako kapa esita le ho hlōleha.Lithako tsa mahlo le li-bearings li ka 'na tsa tsofala, tsa robeha, kapa tsa robeha 'me tsa etsa hore ho be le motsamao o sa rateheng.
2. Molamu Weld fracture
a.Ho hloleha ho tjheseletsa
Bolelele ba ho qhibiliha bo sebetsang hantle le botebo ba fusion ha bo tšoanelehe.Joalo ka ha setšoantšo se bontša-Bolelele bo sebetsang ba ho qhibiliha ke 4mm 'me botebo ba ho kopanya ka thepa ea motheo ke ＜0.5mm
b. Weld Crack Nakong ea ts'ebetso ea welding kapa ka mor'a ho cheselletsa, ho phatloha ha tšepe sebakeng sa welding, ho hlaha ka hare kapa ka ntle ho weld, ho ka boela ha etsahala sebakeng se amehileng ke mocheso.
c.Phoso ea ho tjheseletsa hona joale, haeba hona joale e le nyenyane haholo, arc ha e tsitsa, ho bonolo ho baka li-slag inclusions le mefokolo e sa tsitsang, le tlhahiso e tlaase;Haeba hona joale e le ngata haholo, ho bonolo ho loma ho chesa, le liphoso tse ling, ha ho ntse ho eketseha spatter.
d.Tšebeliso e fosahetseng ea thepa, joalo ka piston rod (material 45Mn) le forkhead (material 42CrMo) e nang le likarolo tse cheselitsoeng.Lisebelisoa tsa motheo: lisebelisoa tsa piston rod 45Mn carbon e lekanang le Ceq = 0.735%, 42CrMo carbon e lekanang le Ceq = 0.825%, weldability e futsanehile haholo, mocheso oa mocheso oa mocheso o bonolo haholo ho hlahisa lisele tse thata, e le hore polasetiki ea weld le boima bo fokotseha, bo futsanehile. crack resistance.
3. Lere le robehileng
Matla a lintho tse bonahalang ha a lekana;Bothata ba sebopeho;Bothata ba Welding
Bakeng sa tlhaiso-leseling e batsi mabapi le moralo kapa tokiso ea hydraulic cylinder, ka kopo ikutloe u lokolohile ho ikopanya le lily ka WhatsApp kapa Wechat ho 8613964561246.
