Sihlala sisithi umbhobho owandisiweyo oshushu ubhekiselele kumbhobho wentsimbi onoxinano oluphantsi ngokwentelekiso kodwa ukucutheka okuqinileyo, uMbutho weMigangatho yeSizwe yaseTshayina umisela ukuba umbhobho wentsimbi owandisiweyo oshushu kufuneka ube ngumbhobho wentsimbi wobubanzi obanzi owandisiweyo kwaye ukhubazeke emva kokuba uwonke. ukufudumeza umbhobho wentsimbi engenanto .. Iteknoloji yokwandisa i-Thermal kukwandisa ububanzi bombhobho ngokusebenzisa i-radial deformation, oko kukuthi, i-non-standard, imizekelo ekhethekileyo yemibhobho engenamthungo inokuveliswa ngokusebenzisa imibhobho eqhelekileyo, kwaye ixabiso liphantsi kunye nemveliso. ukusebenza kakuhle kuphezulu. Yindlela eqhelekileyo yokucubungula imibhobho engenamthungo. Ngenxa yophuhliso oluphezulu lweparameter yophuhliso lwebhoyila yeplanti yamandla kunye nophuhliso olukhulu lwezityalo zepetrochemical, imfuno yemibhobho engenamthungo enobubanzi obukhulu iyakhula, kwaye kunzima kwiiyunithi eziqengqelekayo zemibhobho ukuvelisa ityhubhu engenamthungo edayamitha enkulu kune. 508mm, umlinganiselo wedayamitha yangaphandle ukuya kungqimba eludongeni(D/S)>25, itekhnoloji yokwandiswa kwe-thermal, ingakumbi itekhnoloji yokwandisa ubushushu obuphantsi kwexabiso eliphakathi, ithe chu yaphuhliswa ngoko.

 

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 komgangatho wemveliso, uluhlu olubanzi lwezinto ezikrwada kunye nenkcazo yemveliso, ukuguquguquka kunye nokuguquguquka kwemveliso yebhetshi ephantsi iye yathatha indawo yobugcisa bokwandiswa kohlobo lotsalo lwedayamitha yentsimbi yoshishino lombhobho wentsimbi. .

 

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

 

Inkqubo ngokubanzi yokwandiswa kwe-thermal yombhobho kukulungisa umbhobho kwi-screw ye-lead, ubeke i-anvil ephezulu ene-cone enobubanzi obukhulu kunobubanzi bombhobho kwelinye icala lombhobho, kunye nekhonkco kwaye ulungise enye. jija umbhobho. Umdibaniso phakathi kombhobho kunye ne-anvil ephezulu iphantsi kwe-coil yokufudumeza okuphakathi, ukuze uthintele ukufudumeza ngokukhawuleza kunye nokugqabhuka, kufuneka udlulise amanzi kwi-tube kuqala, uqalise ukufudumeza ikhoyili, kwaye emva kokufikelela kubushushu obuchaziweyo. , i-screw edibanisa ityhubhu ityhala ityhubhu, ukuze ityhubhu ihambe iye kwi-anvil ephezulu kwaye yandise. I-anvil taper ephezulu yandisa i-diameter yombhobho. Emva kokuba umbhobho wonke udlula, umbhobho awuyi kuba ngokuthe 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,≤I-12meter, ukugoba yi-8mm

 

Umzekelo:

ityhubhu yoqobo 610 * 19 eshushu yandisiwe 660 * 16

Ubude bombhobho wokuqala: 12.84imitha

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
