    Ubude:

    Ubude obuqhelekileyo bemibhobho yentsimbi yi-4 000 mm ~ 12 000 mm. Emva kokubonisana phakathi komthengisi kunye nomthengi, kwaye ugcwalise isivumelwano, inokuhanjiswa imibhobho yentsimbi kunye nobude obungaphezu kwe-12 000 mm okanye mfutshane kune-I 000 mm kodwa ingabi mfutshane kune-3 000 mm; ubude obufutshane Inani lemibhobho yentsimbi engaphantsi kwe-4,000 mm kodwa ingabi ngaphantsi kwe-3,000 mm ayisayi kudlula i-5% yenani lilonke lemibhobho yentsimbi ehanjiswayo.

    Ubunzima bokuhanjiswa:
    Xa umbhobho wensimbi uhanjiswa ngokomlinganiselo wangaphandle wegama kunye nobukhulu bodonga olubizwa ngokuba yi-nominal yangaphakathi kunye nobukhulu bodonga, umbhobho wensimbi uhanjiswa ngokobunzima bangempela. Isenokuhanjiswa ngokobunzima bethiyori.
    Xa umbhobho wensimbi uhanjiswa ngokomlinganiselo wangaphandle wegama kunye nobukhulu obuncinci bodonga, umbhobho wensimbi uhanjiswa ngokwesisindo sangempela; amaqela obonelelo kunye nebango ayathethathethana. Kwaye kubonisiwe kwikhontrakthi. Umbhobho wensimbi unokuhanjiswa ngokobunzima bethiyori.

    Ukunyamezela ubunzima:
    Ngokweemfuno zomthengi, emva kokubonisana phakathi komthengisi kunye nomthengi, kunye nekhontrakthi, ukutenxa phakathi kobunzima bokwenene kunye nobunzima bethiyori yombhobho wentsimbi yokuhanjiswa kuya kuhlangabezana nezi mfuno zilandelayo:
    a) Umbhobho wentsimbi enye: ± 10%;
    b) Ibhetshi nganye yemibhobho yentsimbi enobungakanani obuncinane be-10 t: ± 7.5%.

    Imfuneko yoVavanyo

    Uvavanyo lweHydraustatic:

    Umbhobho wentsimbi kufuneka uvavanywe nge-hydraulically nganye nganye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 s, kwaye umbhobho wensimbi akufanele uvuze.

    Emva kokuba umsebenzisi evumile, uvavanyo lwe-hydraulic lunokutshintshwa ngovavanyo lwangoku lwe-eddy okanye uvavanyo lokuvuza kwemagnethi.

    Uvavanyo olungonakaliyo:

    Imibhobho efuna ukuhlolwa okungakumbi kufuneka ihlolwe nge-ultrasonically nganye. Emva kokuba uthethathethwano lufuna imvume yeqela kwaye luchazwe kwikhontrakthi, olunye uvavanyo olungonakalisi lungongezwa.

    Uvavanyo lokucaba:

    Iityhubhu ezinobukhulu obungaphandle obungaphezulu kwe-22 mm ziya kufakwa kuvavanyo lokucaba. Akukho delamination ebonakalayo, amabala amhlophe, okanye ukungcola kufuneka kwenzeke ngexesha lonke uvavanyo.

    Uvavanyo lokuvutha:

    Ngokweemfuno zomthengi kwaye zichazwe kwikhontrakthi, umbhobho wensimbi kunye nobubanzi obungaphandle ≤76mm kunye nobukhulu bodonga ≤8mm lunokwenziwa uvavanyo lokuvutha . Uvavanyo lwenziwa kwiqondo lobushushu begumbi kunye ne-taper ye-60 °. Emva kokuvutha, isantya sokuvutha kobubanzi bangaphandle kufuneka sihlangabezane neemfuno zetafile elandelayo, kwaye izinto zokuvavanya akufanele zibonise ukuqhekeka okanye ukukrazula.
