7.A guga raran isku haysa waxaa la taagan yahay in aanan tijaabada ka dhanka ah taarikada wajiga.
Sahayda 8.The biyaha la qaadi karo si haystaha muunada dhigi heerkulka ugu badan kama badna 35 ℃ at outlet ka haysta soo xareeyo.
Haystaha muunada 9.The shirka waxa uu ku yaalaa at 90 ± 2 ° si weji guddi shucaaca iyo sida jidka in Wajiyada hogaanka ku Hanuuniyaa hoose ee haysta muunada waa in diyaarad la mid ah sida wajiga gudaha ku wareejin ah in guddi shucaaca.
Height 10.Sida haystaha muunada waxaa taaba in ay u oggolaadaan in la gudban, Jamciyadda, ka weji guddi shucaaca dhexeeya imtixaanada iska, laga qabto imtixaanka si booska heegan iyo ku xigeenka qeybsanaan ah.
11.The gubi pilot waa kooban tuubo bir ah.
Gaaska iyo sahayda hawada khadadka 12.The guddi shucaaca ku jira mitir socodka, xakameeya cadaadis, filtarka gacanta iyo aaladaha ammaanka.

14.Dummy guddiga dhaqmaan haysta, dhexdiisa kulaylka meter ka daadanayo oo sii kordhaya.
Product Details ah Faafidda oogada Abuulahab, T Ester
Qalab imtixaan faafinta The olol dusha waa BS 6853 taxane-xawaaraha sare olol steel ahaatid retardant ah, taas oo ku haboon yahay qalabka dhismaha British iyo olol steel heerarka imtixaanka retardant-xawaaraha sare. Heerka waa BS 476-7. Habka baaritaanka waxaa loo isticmaalaa si loo ogaado kordhinta lateral of dusha muunad iyo ku salaysan xawaaraha. Oo dhererka kordhin ay go'aamiso heerka gubashada. BS 476-7 ugu horayn waxa loo isticmaalaa in lagu cabbiro kordhin olol ee meelaha bandhigi on darbiyada iyo saqafka.
Habka imtixaanka waa inay ku qiyaasto ka daadanayo muhiim iftiimeen by ayagoo shiday saamiga la olol yar by Riiqdeediina isbedelka tartiib ah tamarta kulaylka iftiimeen. Tallaabooyinka guddi iftiimeen kulaylka 850mm X 850mm. Haystaha Baaritaanku wuxuu soo xareeyo waa biyo la qaboojiyey iyo qalabaysan saxan dhaqmaan dalool iyo kaamerada a iftiimeen ka daadanayo shidma inay iiraacshay qalooca ka daadanayo waanad ka kaamerada. Qalab Baaritaanku wuxuu leeyahay shuruudo sare on site shaybaarka, iyo user u baahan yahay tallaabooyin ammaanka ka hor inta qalab imtixaanka la soo ururay oo karo.
