Inkqubo yokuvelisa imibhobho yentsimbi engenamthungo inzima kwaye ingqongqo.Emva kokuba umbhobho wensimbi ongenamthungo uveliswe, iimvavanyo ezithile kufuneka zenziwe.Ngaba uyayazi indlela yokuvavanya ukucaba kunye namanyathelo ombhobho wentsimbi ongenamthungo?

1) Yenza isampuli:

1. Isampuli inqunywe kuyo nayiphi na inxalenye yombhobho wensimbi ongenamthungo ogqithise ukuhlolwa okubonakalayo, kwaye isampuli kufuneka ibe yicandelo lombhobho ogcweleyo wemveliso yombhobho.
2. Ubude besampula akufanele bube ngaphantsi kwe-10mm, kodwa bungabi ngaphezu kwe-100mm.Imiphetho yesampulu inokujikelezwa okanye i-chamfered ngokufayilisha okanye ezinye iindlela.Qaphela: Ukuba iziphumo zovavanyo zihlangabezana neemfuno zovavanyo, imiphetho yesampulu ayinakujikelezwa okanye i-chamfered.
3. Ukuba kuya kuqhutyelwa ekupheleni kombhobho wobude obupheleleyo.Ngethuba lovavanyo, ukuchithwa kuya kwenziwa nge-perpendicular kwi-axis longitudinal yombhobho ubude besampuli ukusuka ekupheleni kobuso bombhobho, kwaye ubunzulu bokusika buya kuba ubuncinane be-80% yobubanzi obungaphandle.

2) Izixhobo zovavanyo:

Uvavanyo lunokwenziwa kumatshini wokuvavanya jikelele okanye kumatshini wokuvavanya uxinzelelo.Umatshini wokuvavanya uya kuxhotyiswa ngeeplateni ezimbini eziphezulu kunye nezantsi ezihambelanayo, kwaye ububanzi beeplateni ezihambelanayo ziya kudlula ububanzi besampuli esicaba, oko kukuthi, ubuncinane be-1.6D.Ubude beplate yokucinezela abukho ngaphantsi kobude besampuli.Umatshini wokuvavanya unamandla okunciphisa isampuli kwixabiso elikhethekileyo loxinzelelo.I-platen kufuneka ibe nokuqina okwaneleyo kwaye ikwazi ukulawula uluhlu lwesantya olufunekayo kuvavanyo.

3) Iimeko zovavanyo kunye neenkqubo zokusebenza:

1. Uvavanyo ngokubanzi kufuneka lwenziwe kwigumbi lobushushu obuphakathi kwe-10°C ~ 35°C.Kwiimvavanyo ezifuna iimeko ezilawulwayo, ubushushu bovavanyo buyakuba yi-23°C ± 5°C.Isantya esisicaba sesampulu sinokuba
20-50mm / min.Xa kukho ingxabano, isantya esihambayo seplaten akufanele sidlule i-25mm / min.

2. Ngokwemigangatho efanelekileyo, okanye isivumelwano phakathi kwamaqela amabini, umgama H weplaten kufuneka unqunywe.

3. Beka isampuli phakathi kweeplateni ezimbini ezihambelanayo.I-welds yemibhobho edibeneyo kufuneka ibekwe kwiindawo ezichazwe kwiimveliso ezifanelekileyo kunye nemigangatho.Sebenzisa umatshini wokushicilela okanye umatshini wokuvavanya ukusebenzisa amandla kwicala le-radial, kwaye ngesantya esingekho ngaphezulu kwe-50mm / min, cinezela ngokulinganayo kumgama othe tyaba H, susa umthwalo, ususe isampuli, kwaye ujonge ngokubonakalayo inxalenye yokugoba. yesampulu.

Ukulumkela:

Ngexesha lovavanyo lokucanda, umgama wokucaba H uya kulinganiswa phantsi komthwalo.Kwimeko yokuvala i-flattening evaliweyo, ububanzi boqhagamshelwano phakathi kweendawo zangaphakathi zesampuli kufuneka zibe ubuncinane be-1/2 yobubanzi obungaphakathi b besampula eqhelekileyo emva kokucoca.

Uvavanyo lokusebenza oluthe tyaba lombhobho wensimbi engenamthungo ludlala indima ebalulekileyo kubunzima, indawo yokunyibilika, ukuxhathisa kwe-corrosion kunye noxinzelelo lwepayipi yensimbi engenamthungo, kwaye olu vavanyo kufuneka lwenziwe kakuhle.
