Ngaba nguMbhobho okanye iThubhu?

Kwezinye iimeko amagama angasetyenziswa ngokungafaniyo, nangona kunjalo kukho umehluko obalulekileyo phakathi kwetyhubhu kunye nombhobho, ngokukodwa kwindlela izinto ezilawulwa ngayo kunye nokunyamezela. Iityhubhu isetyenziswa kulwakhiwo ukwenzela ukuba i-diameter yangaphandle ibe ngumlinganiselo obalulekileyo. Iityhubhu zihlala zifakwa kwizicelo ezifana nezixhobo zonyango ezifuna idiameter echanekileyo yangaphandle. I-diameter yangaphandle ibalulekile kuba iya kubonisa ukuba ingabamba kangakanani njengento yokuzinza. Ngelixa imibhobho iqhele ukusetyenziselwa ukuthutha irhasi okanye ulwelo, nto leyo eyenza ukuba kubaluleke ukwazi umthamo. Ukwazi ukuba kungakanani okunokuhamba ngombhobho kubalulekile. Ubume obusetyhula bombhobho buyenza isebenze ngokufanelekileyo xa uphethe uxinzelelo olusuka kulwelo oluqukuqelayo.

Ukuhlelwa

Ulwahlulo lwemibhobho luyishedyuli kunye nobukhulu obuqhelekileyo. Umbhobho ngokuqhelekileyo uyalelwa kusetyenziswa ubungakanani bombhobho oqhelekileyo (NPS) kwaye ngokuchaza idiameter yegama (ubungakanani bombhobho) kunye nenombolo yeshedyuli (ubukhulu bodonga). Inombolo yeshedyuli inokufana kumbhobho wobungakanani obahlukeneyo kodwa ubukhulu bodonga buya kwahluka.
Imibhobho ngokuqhelekileyo iyalelwa ukuya ngaphandle kwedayamitha kunye nobukhulu bodonga; nangona kunjalo, inokuodolwa njenge-OD & ID okanye i-ID kunye nokutyeba kweDonga. Amandla ombhobho axhomekeke kubukhulu bodonga. Ubukhulu betyhubhu buchazwa ngenani lokulinganisa. Amanani egeyiji amancinci abonisa iidayamitha ezinkulu zangaphandle. I-diameter yangaphakathi (ID) yithiyori. Iityhubhu zinokuza ngeemilo ezahlukeneyo ezifana nesikwere, uxande kunye necylindrical, ngelixa imibhobho isoloko ingqukuva. Ubume besetyhula bombhobho benza ukuba amandla oxinzelelo asasazwe ngokulinganayo. Imibhobho ifaka izicelo ezinkulu ezinobungakanani ukusuka kwi-intshi e-½ ukuya kwiifithi ezininzi. Iityhubhu zisetyenziswa ngokubanzi kwizicelo apho kufuneka iidayamitha ezincinci.

Ukuodola iThubhu yakho okanye uMbhobho

Iityhubhu ngokuqhelekileyo iyalelwa ukuya ngaphandle kobubanzi kunye nobukhulu bodonga; nangona kunjalo, inokuodolwa njenge-OD & ID okanye i-ID kunye nokutyeba kweDonga. Nangona i-tubing inemilinganiselo emithathu (i-OD, i-ID kunye nobukhulu bodonga) zimbini kuphela ezinokuchazwa ngokunyamezela kwaye okwesithathu yithiyori. I-tubing idla ngoku-odolwa kwaye ibanjwe kukunyamezela kunye nokunyamezela okungqongqo kunye neenkcukacha kunombhobho. Umbhobho ngokuqhelekileyo uyalelwa kusetyenziswa ubungakanani bombhobho oqhelekileyo (NPS) kwaye ngokuchaza idiameter yegama (ubungakanani bombhobho) kunye nenombolo yeshedyuli (ubukhulu bodonga). Zombini iibhubhu kunye nemibhobho inokusikwa, igobe, ivuswe kwaye yenziwe.

Iimpawu

Kukho iimpawu ezimbalwa eziphambili ezahlula ityhubhu kumbhobho:

Ubume

Umbhobho uhlala ungqukuva. Imibhobho inokuba sisikwere, uxande, kwaye ingqukuva.

Umlinganiselo

Ityhubhu idla ngokuodolwa ngaphandle kobubanzi kunye nobukhulu bodonga. Iityhubhu idla ngokubanjelwa kunyamezelo olungqongqo kwaye olungqongqo ngakumbi kunye neenkcukacha kunombhobho. Umbhobho udla ngokuodolwa kusetyenziswa ubungakanani bombhobho oqhelekileyo (NPS) kwaye ngokuchaza idiameter yegama (ubungakanani bombhobho) kunye nenani leshedyuli (ubukhulu bodonga)

Ubunakho beTelesikophu

Iityhubhu zinokubonwa ngeteleskopu. Iityhubhu zeTelescoping zifanelekile kwizicelo ezahlukeneyo zemathiriyeli kwimikhono okanye ukwandisa ngaphakathi kwenye.

Ukuqina

Umbhobho uqinile kwaye awukwazi ukubunjwa ngaphandle kwezixhobo ezikhethekileyo. Ngaphandle kobhedu kunye nobhedu, iibhubhu zinokubunjwa ngomzamo othile. Ukugoba kunye nokubopha iityhubhu kungenziwa ngaphandle kokuphazamiseka okugqithisileyo, ukushwabana okanye ukuqhekeka.

Usetyenziso

Iityhubhu zisetyenziswa kwizicelo ezifana nezixhobo zonyango ezifuna i-diameter echanekileyo ngaphandle. I-diameter yangaphandle ibalulekile kuba iya kubonisa ukuba ingabamba kangakanani njengento yokuzinza. Imibhobho isetyenziselwa ukuthutha igesi okanye ulwelo, nto leyo eyenza ukuba kube yimfuneko ukwazi umthamo. Ubume obusetyhula bombhobho buwenza usebenze ngokufanelekileyo xa uphethe uxinzelelo olusuka kulwelo oluhamba ngalo.

Iintlobo zesinyithi

Iityhubhu ziyabanda kwaye zishushu ziqengqiwe. Umbhobho ushushu kuphela. Zombini zinokufakwa igalvanized.

Ubungakanani

Imibhobho ivumela izicelo ezinkulu. I-tubing isetyenziswa ngokubanzi apho kufuneka i-diameter encinci.

Amandla

Imibhobho yomelele kunombhobho. Iityhubhu zisebenza ngcono kwizicelo ezifuna ukuqina kunye namandla.

Qhagamshelana neengcaphephe eHunan Great

Ngaphezulu kweminyaka engama-29, uHunan Great uye wazenzela igama njengomthengisi wetyhubhu ekumgangatho wehlabathi kunye nomboneleli wamacandelo, ngokuzingca ekhonza kwimizi-mveliso, amandla, ezonyango, kunye namashishini e-aerospace kwihlabathi liphela.
