Sidla ngokuthi umbhobho eshushu-eyandisiweyo ibhekisela umbhobho yentsimbi kunye ingxinano ephantsi ngokwentelekiso kodwa ukucutheka eyomeleleyo, i-China National Standards Association imisela ukuba umbhobho intsimbi eshushu-eyandisiweyo kufuneka ibe umbhobho yentsimbi enkulu-ububanzi yandisiwe kwaye lukhubazeke emva ukufudumeza jikelele umbhobho yentsimbi engenanto .. Thermal Ukwandiswa iteknoloji kukwandisa ububanzi deformation non-radiation, imifuziselo radial deformation, imodeli non-ezandisiweyo yentsimbi, i-radial deformation ye-radiation ye-seam, i-radiation ye-deformation ekhethekileyo, i-radial deformation, i-radiation, i-deforming ye-radiometer imibhobho inokuveliswa ngokusebenzisa imibhobho eqhelekileyo, kwaye ixabiso liphantsi kwaye ukusebenza kakuhle kwemveliso kuphezulu. Yindlela eqhelekileyo yokucubungula imibhobho engenamthungo. Ngenxa yophuhliso oluphezulu lweparameter yezibiyeli zesityalo samandla kunye nophuhliso olukhulu lwezityalo zepetrochemical, imfuno yemibhobho engenamthungo emikhulu iyanda, kwaye kunzima kwiiyunithi zokuqengqeleka kombhobho ukuvelisa ityhubhu engenamthungo enobubanzi obungaphezu kwe-508mm, umlinganiselo wedayamitha yangaphandle ukuya eludongeni ubukhulu (D/S)> 25, itekhnoloji yolwandiso oluphakathi ngokuthe ngcembe iphuhlise itekhnoloji yolwandiso oluphakathi kancinci kancinci, yona.

 

Umbhobho wokwandisa umbhobho onamanyathelo amabini asetyenziselwa imibhobho yentsimbi eyandisiweyo eshushu idibanisa itekhnoloji yokwandisa i-cone die diameter, i-digital intermediate intermediate intermediate heat heat induction technology, kunye ne-hydraulic technology kumatshini omnye. Ngenkqubo yayo efanelekileyo, ukusetyenziswa kwamandla aphantsi, utyalo-mali oluphantsi lolwakhiwo, kunye nokulunga Umgangatho wemveliso, uluhlu olubanzi lwezinto ezikrwada kunye neenkcukacha zemveliso, ukuguquguquka kunye nokuguquguquka kwebhetshi yokuvelisa igalelo eliphantsi kuthathe indawo yobugcisa bokwandiswa kohlobo lotsalo lobubanzi bombhobho wentsimbi.

 

Kufuneka kuqatshelwe ukuba iimpawu zomatshini wemibhobho yentsimbi eyandisiweyo eshushu ngokuqhelekileyo imbi kakhulu kunemibhobho yentsimbi eshushu.

 

Inkqubo eqhelekileyo yokwandiswa kwe-thermal yombhobho kukulungisa umbhobho kwi-screw ekhokelayo, ubeke i-anvil ephezulu ene-cone enobubanzi obukhulu kunobubanzi bombhobho kwelinye icala lombhobho, kwaye udibanise kwaye ulungise enye i-screw kumbhobho. Umdibaniso phakathi kombhobho kunye ne-anvil ephezulu iphantsi kwe-coil yokufudumeza okuphakathi, ukuze uthintele ukufudumeza ngokukhawuleza kunye nokugqabhuka, kufuneka udlulise amanzi kwityhubhu kuqala, uqalise ukufudumeza ikhoyili, kwaye emva kokufikelela kubushushu obuchaziweyo, isikrufu esidibanisa ityhubhu sityhala ityhubhu, ukuze ityhubhu ihambe iye kwi-anvil ephezulu kwaye iye yande. I-anvil taper ephezulu yandisa i-diameter yombhobho. Emva kokuba umbhobho wonke udlula, umbhobho awuyi kuba tye ngenxa yenkqubo yokwandisa i-thermal, ngoko kufuneka iqondise.

Oku ngasentla kumxholo osisiseko weteknoloji yokwandisa i-thermal.

 Oku kulandelayo yifomula efanelekileyo yombhobho owandisiweyo we-thermal

 

Ubunzima obandisiweyo:

carbon steel: (ubukhulu bobubanzi)× ubukhulu× 0.02466 = ubunzimat yemitha enye(kg)

ingxubevange: (i-diameter-thickness)× ubukhulu× 0.02483 = ubunzimayemitha enye (kg)

inani leemitha emva kokushushu kwandisiwe:

ityhubhu yokuqala Ububanzi÷ Idayamitha eshushu eyandisiweyo× 1.04× ubude *

 

iimitha ityhubhu yokuqala:

ubude obandisiweyo× (ububanzi÷ Idayimitha yetyhubhu yokuqala÷ 1.04)

 

isantya:

100000÷ (ubukhulu bokuqala bedayamitha× ubukhulu)

 

ubukhulu:

ubukhulu obandisiweyo (1 ixesha) ) = Ubukhulu betyhubhu yoqobo× 0.92

Ubukhulu obandisiweyo (amaxesha ama-2) = Ubukhulu betyhubhu yoqobo * 0.84

 

Ububanzi :

Idayamitha eyandisiweyo = ubukhulu bokubumba + ubukhulu obandisiweyo× 2

Ubungakanani bokungunda: i-diameter eyandisiweyo-2 * iindonga ezandisiweyo Ukutyeba

 

Ukunyamezela kwe-diameter:

Ububanzi＜426mm, ukunyamezela±2.5

Ububanzi 426-630mm, ukunyamezela±3

Ububanzi＞630mm, ukunyamezela±5

 

I-ellipality:

Ububanzi＜426mm, ukunyamezela±2

Ububanzi＞426mm, ukunyamezela±3

 

Ukutyeba:

ubukhulu≤20mm, ukunyamezela﹢2 ,-1.5

ubukhulu≤40mm﹢3 ,-2

Umbhobho wokwenza uMbhobho ulingane

﹢5 ,-0

 

Ngaphakathi nangaphandle ekuqaleni:

 

Ubunzulu bomkrwelo: 0.2mm, ubude: 2cm, ibizwa ngokuba ngumkrwelo. Ayivumelekanga

Ukuthe tye: ≤6imitha, ukugoba yi-5mm,≤12imitha, ukugoba yi-8mm

 

Umzekelo:

ityhubhu yoqobo 610 * 19 eshushu yandisiwe 660 * 16

Ubude bombhobho wokuqala: 12.84meter

Ubukhulu obandisiweyo:19*0.92=17.48(1 ixesha)

19*0.84=15.96(2 amaxesha）

Ubude bombhobho owandisiweyo:610÷660*1.04*12.84=12.341962

Idayamitha eyandisiweyo:625+17.48*2+1=660.96(ixesha eli-1)

625+15.96*2+1=657.92(2 amaxesha)

 

Ubungakanani bemodyuli: 660-2 * 16 = 628
