Intsimbi ye-L245 yePipeline, yena umlinganiselo wesisombululo

Ukufunyanwa kwe-Eddy yangoku yombhobho we-Changsha kusebenza kuphela kwizinto zokuqhuba.Ukuba izixhobo ezingezizo zokuqhuba zisetyenzisiwe, i-vortex emile okwangoku ayinakunyanzelwa kwaye i-eddy current ayinakusetyenziselwa ukubonwa.Uvavanyo lwangoku lwe-Eddy lufanelekile ngakumbi kuvavanyo lomphezulu kunye nokufutshane komphezulu wezinto zokuqhuba.Uvavanyo lwangoku lwe-Eddy alufuni ukudityaniswa.Intsimi ye-electromagnetic eyonwabileyo kuvavanyo lwangoku lwe-eddy ngokusisiseko liza lombane elineempawu zamaza kunye neempawu zamasuntswana, ke ngoko iprobe (i-coil) kunye nesixhobo sokusebenza sinokusasazwa ngaphandle kokudityaniswa, ngoko ke ubhaqo olungaqhagamshelwanga lunokwenziwa.Oku kungcono kunokubonwa kwe-ultrasonic.Ngenxa yokuba i-ultrasonic wave yetyhubhu yebhoyila yoxinzelelo oluphantsi iliza lomatshini, inokuhamba kuphela kwizinto eziphathekayo.Ke ngoko, ukubonwa kwe-ultrasonic kufuneka kudityaniswe phakathi kweprobe kunye nomsebenzi.Uvavanyo lwangoku lwe-Eddy lunokufikelela kuvavanyo olukhawulezayo noluzenzekelayo.Uvavanyo lwangoku lwe-Eddy lunokulungela ukuchongwa kweentsimbi zobushushu obuphezulu ngenxa yokuqhutywa kombane kumaqondo obushushu aphezulu.Ubhaqo lokuhamba kombhobho weChangsha lukwalungele ukuchongwa kwezinto ezinokwakheka okukhethekileyo, okoko nje ikhoyili yenziwe kwiimilo ezahlukeneyo.Iqhele ukusetyenziswa kumbhobho izinto brinell, rockwell, Vickers ubulukhuni 3 iintlobo.Umbhobho weChangsha "umbhobho wentsimbi ongenamthungo weBoiler yoxinzelelo oluphantsi kunye noxinzelelo oluphakathi".Kukho iintlobo ezingama-43 zenkcazo yombhobho we-changsha kuzo zonke iintlobo zezakhiwo zebhoyila, ezinobubanzi obuyi-10 ~ 426mm.Kukho iindidi ezingama-29 zobukhulu bodonga ukusuka kwi-1.5 mm ukuya kwi-26mm.Nangona kunjalo, ububanzi bangaphandle kunye nobukhulu bodonga lombhobho womphunga oshushu kakhulu, umbhobho omkhulu womsi, umbhobho omncinci womsi kunye nombhobho we-arch wezitena osetyenziswa kwibhoyila ye-locomotive ichazwe ngenye indlela.Idayamitha yangaphandle yombhobho we-changsha yi-22 ~ 530mm, kwaye ubukhulu bodonga yi-20 ~ 70mm.Ukutsalwa okubandayo (okubandayo okuqengqelekayo) ityhubhu ububanzi 10 ~ 108mm, ubukhulu bodonga 2.0 ~ 13.0mm.Umgangatho wokubonakala: ukuqhekeka, ukugoqa, ukuqengqeleka, ukukrala, ukuhlukana kunye nemibimbi akuvumelekanga kwindawo yangaphakathi nangaphandle yombhobho wensimbi.Ezi ziphene kufuneka zipheliswe ngokupheleleyo.Ubunzulu bococeko abuyi kudlula ukutenxa okungalunganga kobunzima bodonga lwegama, kwaye ubungakanani bodonga lokwenene kwindawo yokucoca abuyi kuba ngaphantsi kobungqingqwa obuvumelekileyo bodonga.Isitshixo kukwamkela iindlela ezahlukeneyo ngokweemeko ezahlukeneyo, njengokwamkela i-adiabatic kunye nezixhobo eziphikisayo ukuvimba ilangatye ekutshiseni isakhiwo sentsimbi ngokuthe ngqo, ukunciphisa isantya sokuhambisa ubushushu kunye nokulibazisa ixesha lokunyuka kweqondo lobushushu kunye nokuqina kokuqina kwesakhiwo sentsimbi. .Kodwa nokuba yeyiphi na indlela, umgaqo uyafana.Ukugquma okungatshiyo luhlobo lwemilinganiselo yetekhnoloji yokumelana nomlilo ngoku.Ngenxa yempembelelo yezinto ezingcolileyo kumgangatho wombhobho weChangsha, iimveliso ezikumgangatho ophezulu zineemfuno ezingqongqo kakhulu kulawulo lwezinto ezinobungozi kunye nokubandakanywa kwipayipi yepayipi yeChangsha.Kuyimfuneko ukulawula umxholo wezinto ezahlukeneyo zokungcola kwinqanaba eliphantsi kakhulu, kwaye inkqubo yokucoca ngaphandle kwesithando somlilo isoloko isetyenziselwa ukuvelisa ukuqinisekisa ukucoceka kwayo.Ubushushu betyhubhu yebhoyila ngokubanzi bungaphantsi kwe-350 ℃, umbhobho wasekhaya wenziwa ubukhulu becala.I-10, i-20 ye-carbon edibeneyo yentsimbi ye-Changsha umbhobho okanye umbhobho otsalwa ngokubanda.
