Tinowanzo taura kuti pombi inowedzerwa nekupisa inoreva pombi yesimbi ine density yakaderera asi ine shrinkage yakasimba, China National Standards Association inoti pombi yesimbi inowedzerwa nekupisa inofanira kunge iri pombi yesimbi yakakura uye yakakanganisika mushure mekudziya kwese kwepombi yesimbi isina chinhu. Tekinoroji yekuwedzera kupisa ndeyekuwedzera dhayamita yepombi kuburikidza ne radial deformation, kureva kuti, mhando dzisiri dzemhando yepamusoro, dzakakosha dzepombi dzisina musono dzinogona kugadzirwa uchishandisa pombi dzakajairwa, uye mutengo wakaderera uye kushanda zvakanaka kwekugadzira kwakakwira. Inzira yakajairika yekugadzirisa pombi dzisina musono. Nekuda kwekuvandudzwa kwezviyero zvepamusoro zvemaboiler emagetsi uye kukura kukuru kwezvimiti zve petrochemical, kudiwa kwemapombi asina musono makuru kuri kuwedzerawo, uye zvakaoma kuti mayuniti ekumonera pombi agadzire pombi isina musono ine dhayamita inopfuura 508mm, chiyero chedhayamita yekunze kune ukobvu hwemadziro (D/S)>25, tekinoroji yekuwedzera kupisa, kunyanya tekinoroji yekuwedzera kupisa kwepakati nepakati inodhura zvishoma nezvishoma yakagadzira zvishoma nezvishoma.
Chinopa simba chekuwedzera mapaipi esimbi chine nhanho mbiri chinoshandiswa pakuisa mapaipi esimbi anopisa, chinosanganisa tekinoroji yekuwedzera dhayamita yekoni, tekinoroji yekupisa yedhijitari yepakati penguva yekudzikisa, uye tekinoroji yehydraulic mumuchina mumwe chete. Nemaitiro ayo akakodzera, kushandiswa kwesimba kwakaderera, mari shoma yekuvaka, uye kunaka. Hunhu hwechigadzirwa, mhando dzakasiyana dzezvinhu zvakagadzirwa uye zvirevo zvechigadzirwa, kuchinjika uye kuchinjika kwakaderera kwekugadzirwa kwebatch zvakatsiva tekinoroji yekuwedzera dhayamita yedhiyamita yedhiyamita yeindasitiri yemapaipi esimbi.
Zvinofanira kucherechedzwa kuti hunhu hwemapombi esimbi anowedzerwa nekupisa kazhinji hwakaipa zvishoma pane mapaipi esimbi anomonerwa nekupisa.
Maitiro akajairika ekuwedzera kupisa kwepombi ndeyekugadzirisa pombi pa screw ye lead, kuisa screw yekumusoro yakaita se cone ine dhayamita yakakura kupfuura dhayamita yepombi kune rimwe divi repombi, uye batanidza woisa screw imwe iri mupombi. Kubatana pakati pepombi ne screw yekumusoro kuri pasi pe intermediate frequency heating coil, kuti udzivise kupisa nekukurumidza uye kuputika, unofanirwa kupinza mvura mu tube kutanga, wotanga kupisa coil, uye mushure mekusvika patembiricha yakatarwa, screw inobatanidza tube inosunda tube, kuitira kuti tube ifambe ichienda ku screw yekumusoro uye iwedzere. Top anvil taper inowedzera dhayamita yepombi. Mushure mekunge pombi yese yapfuura, pombi haizove yakatwasuka nekuda kwekuwedzera kupisa, saka anofanira kuiruramisa.
Zviri pamusoro apa ndizvo zvinonyanya kukosha mutekinoroji yekuwedzera kupisa.
Iyi ndiyo fomura yakakodzera yepombi yakawedzerwa nekupisa
Huremu hwakawedzerwa:
simbi yekabhoni: (dhayamita-ukobvu)× ukobvu× 0.02466 = kuremat yemita imwe (kg)
chiwanikwa: (dhayamita-ukobvu)× ukobvu× 0.02483 = huremuyemita imwe (kg)
huwandu hwemamita mushure mekudziya kwakawedzerwa：
Dhayamita yechubhu yepakutanga÷ dhayamita inopisa yakawedzerwa× 1.04× kureba *
mita dzemachubhu ekutanga：
kureba kwakatambanudzwa× (dhayamita÷ dhayamita yechubhu yepakutanga÷ 1.04)
kumhanya:
100000÷ (ukobvu hwepakutanga hwedhayamita× ukobvu)
ukobvu:
ukobvu hwakakura (kamwe chete) ) = Ukobvu hwepakutanga hwechubhu× 0.92
Ukobvu hwakakura (kaviri) = Ukobvu hwepakutanga hwechubhu*0.84
Dhayamita:
Dhayamita yakawedzerwa = saizi yeforoma + ukobvu hwakawedzerwa× 2
Saizi yemuforoma: dhayamita yakawedzerwa—2 * madziro akakura Ukobvu
Kushivirira kwedhayamita：
Dhayamita＜426mm, kushivirira±2.5
Dhayamita426-630mm, kushivirira±3
Dhayamita＞630mm, kushivirira±5
Kutenderera kwemazwi:
Dhayamita＜426mm, kushivirira±2
Dhayamita＞426mm, kushivirira±3
Ukobvu:
ukobvu≤20mm, kushivirira﹢2 ，—1.5
ukobvu≤40mm，﹢3 ，—2
Pombi yekugadzira pombi
﹢5 ，—0
Mukati nekunze kwemavara:
Kudzika kwekukwenya: 0.2mm, kureba: 2cm, kunonzi kukwenya. Hazvibvumirwi
Kutwasuka: ≤6meter, kukotama kuri 5mm，≤12meter, kukotama kuri 8mm
Semuenzaniso:
Chubhu yekutanga 610*19 inopisa yakawedzerwa 660*16
Kureba kwepombi yepakutanga: 12.84meter
Ukobvu hwakakura:19*0.92=17.48(nguva imwe)
19*0.84=15.96()Kaviri）
Kureba kwepombi kwakawedzerwa: 610÷660*1.04*12.84=12.341962
Dhayamita yakawedzerwa: 625+17.48*2+1=660.96(nguva imwe)
625+15.96*2+1=657.92(kaviri)
Saizi yeModule: 660-2 * 16 = 628
