Pano isu takanyanya kunyora ari pazasi 3 akatyoka mamiriro-Bush Yakaputsika kana Rod Ziso Yakaputsika kana imwe Mount Connection Kukundikana;Rod Weld fracture uye tsvimbo yakatyoka.
1. Gwenzi Rakatyoka, Tsvimbo Ziso Rakatyoka,kana kumwe Kutadza Kwekubatanidza Mount
Silinda inoiswa nenzira dzakasiyana siyana: tsvimbo kana mbiya maziso, trunnion, flange, nezvimwe.Kana silinda yakawandisa-yakaremerwa kana kusarongeka, kushushikana kwakanyanya kunoshandiswa kune inokwirisa yekubatanidza iyo inoguma nekupfeka nekukurumidza kana kutadza.Tsvimbo yeziso uye mabhengi anogona kupera, kuchekwa, kana kutyoka achigadzira slop uye kufamba kusingafadzi.
2. Rod Weld kuputsika
a.Welding kukundikana
Kubudirira kunyunguduka kureba uye kudzika kwe fusion hazvikodzeri.Sezvinoratidzwa nemufananidzo-Inoshanda kunyunguduka kureba i4mm uye Hudzamu hwekusanganiswa nehwaro zvinhu ＜0.5mm
b.Weld Crack Mukugadzira simbi kana mushure mekuputira, simbi inoputika munzvimbo yewelding, inomuka mukati kana kunze kweweld, inogonawo kuitika munzvimbo inopisa.
c.Yakashata welding ikozvino, kana ikozvino idiki, iyo arc haina kugadzikana, nyore kukonzeresa slag inclusions uye unwelded kuremara, uye kuderera kubereka;Kana yazvino yakawandisa, nyore kuruma kupisa, uye zvimwe zvirema, uchiwedzera spatter.
d.Kusashandiswa zvakanaka kwezvinhu, senge piston rod (material 45Mn) uye forkhead (material 42CrMo) ine welded zvikamu.Base zvinhu: piston tsvimbo zvinhu 45Mn kabhoni yakaenzana Ceq = 0.735%, 42CrMo kabhoni yakaenzana Ceq = 0.825%, weldability yakashata kwazvo, pakamuri tembiricha welding iri nyore kwazvo kugadzira nyama yakaoma, kuitira kuti weld tishu plasticity uye kuoma kuderera, kuderera. crack resistance.
3. Tsvimbo yakatyoka
Simba renyama harina kukwana;Dambudziko rechimiro;Welding Dambudziko
