Uvavanyo lokuqina luya kwenziwa phakathi kobungqingqwa bemveliso. Uvavanyo lokuqina rhoqo luya kuba ziisampuli ezimbini zemveliso nganye kwindawo yonyango lobushushu kwaye iziphumo zovavanyo lokuqina ziya kuxelwa kwingxelo yovavanyo lwemathiriyeli.

Imfuneko yoVavanyo
Uvavanyo lweHydraustatic:
Umbhobho weNtsimbi kufuneka uVavanywe ngokweHydraulically enye nenye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 S, kwaye iPipe yensimbi akufanele ivuze. Okanye uVavanyo lweHydraulic lunokuthi lutshintshwe nguVavanyo lwangoku lwe-Eddy okanye uvavanyo lokuvuza kweMagnetic Flux.
Uvavanyo olungonakaliyo:
Imibhobho efuna uPhononongo olungakumbi kufuneka ihlolwe ngokwe-Ultrasonically nganye nganye. Emva kokuba uThethathethwano lufuna imvume yeQela kwaye luchazwe kwiKhontrakthi, olunye uvavanyo olungabhubhisi lunokongezwa.
Uvavanyo lokucaba:
Iityhubhu ezinoMda waNgaphandle oMkhulu kune-22 mm ziya kuHlelelwa kuVavanyo lokuNcandwa. Akukho kuDelamination kubonakalayo, amabala amhlophe, okanye ubumdaka obunokuthi kwenzeke ngexesha lovavanyo lulonke.
Uvavanyo lokuqina:
Ngombhobho wamaBanga P91, P92, P122, kunye neP911, Brinell, Vickers, okanye Rockwell Ukuqina kovavanyo kuya kwenziwa kwiSampulu kwiLoti nganye.
