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.

Emva kokuba uMsebenzisi eVumelana, uvavanyo lweHydraulic lunokutshintshwa luVavanyo lwangoku lwe-Eddy okanye uvavanyo lokuvuza kweMagnetic Flux.

Uvavanyo olungonakaliyo:

Imibhobho efuna uHlolo oluthe kratya kufuneka ihlolwe ngokwe-Ultrasonically nganye nganye. Emva kokuba uThetha-thethwano lufuna imvume yeQela kwaye luchazwe kwiKhontrakthi, olunye uvavanyo olungabhubhisi lunokongezwa.

Uvavanyo lokucaba:

Iityhubhu ezinoMda waNgaphandle oMkhulu kune-22 mm ziyakuBekelwa kuVavanyo lokuNcandwa. Akukho Kulahlwa okubonakalayo, amabala amhlophe, okanye ubumdaka obunokuthi kwenzeke ngexesha lovavanyo lulonke.

Uvavanyo lokuqina:

Ngombhobho wamaBanga P91, P92, P122, kunye no-P911, Brinell, Vickers, okanye iimvavanyo zokuqina zeRockwell ziya kwenziwa kumzekelo osuka kwindawo nganye.

Uvavanyo lokugoba:

Kumbhobho obubanzi bayo budlula i-NPS 25 kwaye ububanzi bayo bobungqingqwa bodonga yi-7.0 okanye ngaphantsi iya kufakwa kuvavanyo lokugoba endaweni yovavanyo lokucaba. Omnye umbhobho obubanzi bayo bulingana okanye obudlula i-NPS 10 unokunikwa uvavanyo lokugoba endaweni yovavanyo lokucaba ngokuxhomekeke kwimvume yomthengi.
