Ntawm no peb tau teev tseg hauv qab no 3 qhov xwm txheej tawg-Bush Broken lossis Rod Eye Broken lossis lwm yam Mount Connection Failure;Qws Weld tawg thiab Qws tawg.
1. Bush tawg, qws qhov muag tawg, los yog lwm yam Mount Connection Failure
Lub tog raj kheej yog mounted los ntawm ntau txoj kev: pas nrig lossis lub thoob qhov muag, trunnion, flange, thiab lwm yam.Thaum lub cylinder yog overloaded los yog misaligned, kev ntxhov siab ntau dhau yog siv rau kev sib txuas mounting uas ua rau hnav sai dua lossis tsis ua haujlwm.Qws qhov muag bushings thiab bearings tuaj yeem hnav, chipped, los yog tawg ua rau txoj kab nqes thiab kev txav tsis zoo.
2. Qws Weld tawg
a. vuam tsis ua hauj lwm
Qhov zoo melting ntev thiab qhov tob ntawm fusion tsis tsim nyog.Raws li daim duab qhia tau hais tias-Qhov zoo melting ntev yog 4mm thiab qhov tob ntawm fusion nrog cov khoom siv hauv paus yog ＜0.5mm
b. Weld Crack Nyob rau hauv cov txheej txheem vuam los yog tom qab vuam, hlau rupture nyob rau hauv lub vuam cheeb tsam, nws tshwm sim nyob rau hauv los yog sab nraum lub vuam, kuj yuav tshwm sim nyob rau hauv lub tshav kub-tshem tawm tsam.
c.Tsis zoo welding tam sim no, yog tias tam sim no me me dhau, lub arc tsis ruaj khov, yooj yim ua rau slag inclusions thiab unwelded defects, thiab tsawg productivity;Yog tias qhov tam sim no ntau dhau, yooj yim rau tom hlawv, thiab lwm yam tsis xws luag, thaum nce spatter.
d.Kev siv cov khoom siv tsis raug, xws li piston pas nrig (khoom siv 45Mn) thiab forkhead (khoom siv 42CrMo) uas muaj cov khoom siv welded.Cov khoom siv hauv paus: piston pas nrig khoom 45Mn carbon sib npaug Ceq = 0.735%, 42CrMo carbon sib npaug Ceq = 0.825%, weldability tsis zoo, nyob rau hauv chav tsev kub vuam yog yooj yim heev los tsim cov ntaub so ntswg hardened, kom cov ntaub so ntswg weld plasticity thiab toughness poob, tsis zoo. tawg tsis kam.
3. Qws tawg
Cov khoom siv zog tsis txaus;Teeb meem ntawm cov qauv;Vuam teeb meem
