Sihlala sithi umbhobho oshushu ubhekisa kumbhobho wentsimbi onoxinano oluphantsi kodwa uncipha ngamandla, i-China National Standards Association imisela ukuba umbhobho wentsimbi oshushu kufuneka ube ngumbhobho wentsimbi omkhulu nowongeziweyo nowonakaliswe emva kokufudumeza umbhobho wentsimbi ongenanto. Itekhnoloji yokwandisa ubushushu kukwandisa ububanzi bombhobho ngokuguqulwa kwe-radial, oko kukuthi, iimodeli ezikhethekileyo zemibhobho engenamthungo ezinokwenziwa kusetyenziswa imibhobho eqhelekileyo, kwaye iindleko ziphantsi kwaye ukusebenza kakuhle kwemveliso kuphezulu. Yindlela eqhelekileyo yokucubungula imibhobho engenamthungo. Ngenxa yophuhliso oluphezulu lwee-parameter zeebhoyila zezityalo zamandla kunye nophuhliso olukhulu lwezityalo ze-petrochemical, imfuno yemibhobho engenamthungo enkulu nayo iyanda, kwaye kunzima kwiiyunithi zokuqengqeleka kwemibhobho ukuvelisa umbhobho ongenamthungo onobubanzi obungaphezulu kwe-508mm, umlinganiselo wobubanzi bangaphandle nobukhulu bodonga (D/S)>25, itekhnoloji yokwandisa ubushushu, ingakumbi itekhnoloji yokwandisa ubushushu obuphakathi engabizi kakhulu iye yaphuhliswa kancinci kancinci.
I-expander yepayipi yokuqhumisa enamanyathelo amabini esetyenziselwa imibhobho yentsimbi eshushu edibanisa iteknoloji yokwandisa ububanzi be-cone die, iteknoloji yokufudumeza i-digital intermediate frequency induction, kunye neteknoloji ye-hydraulic kumatshini omnye. Ngenkqubo yayo efanelekileyo, ukusetyenziswa kwamandla aphantsi, utyalo-mali oluphantsi lokwakha, kunye nomgangatho olungileyo. Umgangatho wemveliso, uluhlu olubanzi lwezixhobo ezikrwada kunye neenkcukacha zemveliso, ukuguquguquka kunye nokuguquguquka kwebhetshi yemveliso yokufaka okuphantsi kuthathe indawo yeteknoloji yokwandisa ububanzi be-pull-type yesiqhelo yoshishino lwemibhobho yentsimbi.
Kufuneka kuqatshelwe ukuba iipropati zoomatshini zemibhobho yentsimbi ekhuliswe ngobushushu ngokubanzi zimbi kancinci kunemibhobho yentsimbi eqengqelekayo ngobushushu.
Inkqubo eqhelekileyo yokwandiswa kobushushu bombhobho kukulungisa umbhobho kwisikrufu sentambo, ubeke i-anvil ephezulu enemilo yekhoni enobubanzi obukhulu kunobubanzi bombhobho kwelinye icala lombhobho, uze udibanise kwaye ulungise esinye isikrufu kumbhobho. Unxibelelwano phakathi kombhobho kunye ne-anvil ephezulu luphantsi kwe-intermediate frequency heating coil, ukuze ulwe nobushushu ngokukhawuleza kakhulu kwaye buqhume, kufuneka udlulise amanzi kumbhobho kuqala, uqale ukufudumala kwe-coil, kwaye emva kokufikelela kubushushu obuchaziweyo, isikrufu esidibanisa umbhobho sityhala umbhobho, ukuze umbhobho uhambe uye kwi-anvil ephezulu kwaye wolule. I-anvil ephezulu i-taper yandisa ububanzi bombhobho. Emva kokuba umbhobho wonke udlulile, umbhobho awuyi kuba uthe tye ngenxa yenkqubo yokwandiswa kobushushu, ngoko ke kufuneka awulungise.
Oku kungasentla kusisiseko sobuchwepheshe bokwandisa ubushushu.
Le ilandelayo yifomyula efanelekileyo yombhobho owandisiweyo wobushushu
Ubunzima obwandisiweyo:
intsimbi yekhabhoni: (ubukhulu bobubanzi)× ubukhulu× 0.02466 = ubunzimat yemitha enye (kg)
ingxubevange: (ubukhulu bobubanzi)× ubukhulu× 0.02483 = ubunzimayemitha enye (kg)
inani leemitha emva kokwandiswa okushushu：
Ububanzi betyhubhu yoqobo÷ ububanzi obushushu obukhulisiweyo× 1.04× ubude *
iimitha zetyhubhu zokuqala：
ubude obandisiweyo× (ububanzi÷ ububanzi betyhubhu yokuqala÷ 1.04)
isantya:
100000÷ (ubukhulu bobukhulu bokuqala bedayamitha× ubukhulu)
ubukhulu:
ubukhulu obandisiweyo (ixesha eli-1) ) = Ubukhulu betyhubhu yoqobo× 0.92
Ubukhulu obwandisiweyo (izihlandlo ezi-2) = Ubukhulu betyhubhu yoqobo*0.84
Ububanzi:
Ububanzi obubanzi = ubungakanani bomngundo + ubukhulu obubanzi× 2
Ubungakanani bomngundo: ububanzi obubanzi obukhulisiweyo—2 * iindonga ezikhulisiweyo Ubukhulu
Ukunyamezelana kobubanzi：
Ububanzi＜426mm, ukunyamezelana±2.5
Ububanzi426-630mm, ukunyamezelana±3
Ububanzi＞630mm, ukunyamezelana±5
Ukucaca kwesandi:
Ububanzi＜426mm, ukunyamezelana±2
Ububanzi＞426mm, ukunyamezelana±3
Ubukhulu:
ubukhulu≤20mm, ukunyamezelana﹢2 ，—1.5
ubukhulu≤40mm，﹢3 ，—2
Umbhobho wokwenza ukufakwa kombhobho
﹢5 ，—0
Ngaphakathi nangaphandle komkrwelo:
Ubunzulu bokukrwela: 0.2mm, ubude: 2cm, kuthiwa kukukrwela. Akuvumelekanga
Ukuqondakala: ≤Imitha eyi-6, ukugoba yi-5mm，≤I-12meter, ukugoba yi-8mm
Umzekelo:
Ityhubhu yoqobo 610*19 eshushu ekhuliswe 660*16
Ubude bombhobho wokuqala: 12.84meter
Ubukhulu obandisiweyo: 19*0.92=17.48(ixesha eli-1)
19*0.84=15.96(IsiNgesi)Amaxesha ama-2）
Ubude obunwetshiweyo bombhobho: 610÷660*1.04*12.84=12.341962
Ububanzi obandisiweyo: 625+17.48*2+1=660.96(ixesha eli-1)
625+15.96*2+1=657.92(izihlandlo ezi-2)
Ubungakanani beModyuli: 660-2 * 16 = 628
