1. Dhuumo bir ah oo kulul oo duuban
Duubista kulul waxa loola jeedaa kulaylinta birta birta heerkul ku haboon iyo samaynta tuubo bir ah oo aan xidhnayn iyada oo loo marayo shubid joogto ah iyo rogrogid.Dhuumaha birta ah ee kulul ee kulul ayaa leh sifooyinka xoogga sare, caagagga wanaagsan iyo waxqabadka alxanka sababtoo ah qallafsanaanta caagga ah ee qumman ee gudaha tuubada birta ka dib habab badan oo isdaba-joog ah.Marka la eego heerka gaarsiinta, tuubooyinka birta ee kulul ee duuban ayaa loo qaybiyaa saddex gobol: maqaarka madow, maqaarka siman iyo maqaarka shiida.Maqaarka madow waa xaalad aan lahayn daawaynta dusha sare, maqaarka siman waa xaalada daaweynta dusha sare ka dib, maqaarka shiidana waa gobolka.Heerkulka sare ayaa dhalaalay
2. Kuleyl lagu daaweeyay tuubo bir ah oo aan lahayn
Daawaynta kulaylka ee dhuumaha birta ah ee aan xidhnayn waxa loola jeedaa kulaylinta, dahaarka iyo qaboojinta tuubada birta ah ee bilaa bilaa xad ah si ay u yeelato astaamo farsamo iyo muuqaal ah.Xaaladda gaarsiinta ee tuubooyinka birta ee kulaylka lagu daweeyay ayaa badanaa la tirtiraa ama la caadiyeeyaa.Xaaladda nuugista waxaa loola jeedaa kuleylinta tuubada birta heerkul gaar ah, haynta muddo, ka dibna si tartiib ah u qaboojiso heerkulka qolka;Xaaladda caadiga ah waxaa loola jeedaa kuleylinta tuubada birta heerkul gaar ah, haynta muddo, ka dibna biyaha qaboojinta ama saliidda qaboojinta si ay u yeelato awood sare iyo qallafsanaan.
3. Farqiga u dhexeeya tuubooyinka birta ah ee kulul iyo kulaylka lagu daweeyay
Kuleyl kulul iyo daawaynta kulaylku waa laba hab oo kala duwan oo soo saarista tuubooyinka birta ah ee aan fiicneyn, iyo heerka gaarsiinta sidoo kale waxay leedahay kala duwanaansho gaar ah.Dhuumaha birta ah ee kulul ee kulul waxay leedahay caag wanaagsan, waxqabadka alxanka iyo xoogga sare, waxayna ku habboon tahay caabbinta cadaadiska, caabbinta kulaylka, caabbinta daxalka iyo meelaha kale.Tuubooyinka birta ah ee kulaylka lagu daweeyay waxay leeyihiin qallafsanaan sare, xoog iyo sifooyin farsamo oo kale ka dib markii la tirtiro ama la hagaajiyo daaweynta, waxayna ku habboon yihiin beeraha injineernimada ee u baahan inay u adkeystaan ​​cadaadiska sare iyo culeysyada culus.
Marka la soo koobo, marka la dooranayo tuubooyinka birta ah ee aan fiicneyn, xulashada waa in lagu saleeyaa baahida isticmaalka dhabta ah iyo heerka gaarsiinta ee tuubooyinka birta ah.Isla mar ahaantaana, fiiro gaar ah u yeelo iibsashada alaabooyinka ay soo saaraan soosaarayaasha caadiga ah si loo hubiyo in tayadooda iyo waxqabadkooda ay buuxiyaan shuruudaha.
