    Isishwankathelo

    Isicelo

    Isetyenziswa ikakhulu ukwenza umgangatho ophezulu wekhabhoni yentsimbi, intsimbi yesakhiwo sealloyi kunye nentsimbi engatyiwa ngumthungo yemibhobho yentsimbi engenamthungo yoxinzelelo oluphezulu nangaphezulu kwemibhobho yebhoyila yomphunga.

    Isetyenziswa ikakhulu kuxinzelelo oluphezulu kunye nenkonzo yobushushu obuphezulu bebhoyila (ityhubhu yeheater, ityhubhu yokufudumeza, ityhubhu yesikhokelo somoya, ityhubhu ephambili yomphunga kwizibiyeli zoxinzelelo oluphezulu kunye noxinzelelo oluphezulu). Ngaphantsi kwesenzo segesi ephezulu yokushisa kunye nomphunga wamanzi, ityhubhu iya ku-oxidize kwaye idle. Kuyadingeka ukuba umbhobho wensimbi unokuqina okuphezulu, ukuchasana okuphezulu kwi-oxidation kunye nokugqwala, kunye nokuzinza okuhle kwesakhiwo.

    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.
