Momo Takirua Haumaru
Tauira A68Y-P54110V, A68Y-P54140V, A68Y-P54200V, A68Y-P5432V, A68Y-P5445V, A68Y-P5464V
Diamita Ingoa DN 40-150

E tika ana mo te mamaoa, te hau me etahi atu taputapu reo, te paipa ranei (te mahana mahi ≤560 ℃ me te pehanga mahi ≤20MPa) hei parepare teitei.

  1. Ma te hoahoa o te hanganga o te puna o te puna, he nui te rere o te paera, he hanganga ngawari, he pai te mahi hiri, he tika te pehanga whakatuwhera, he iti te pupuhi, he pai te whakarereke me etahi atu ahuatanga.
  2. Ko te nohoanga takirere ko Laval nozzle valve seat. I te wa e rere ana i roto i te putanga tuuru takirere, ka eke te mamaoa ki runga i te tere supersonic me te whakarea tukunga nui, ka taea te whakaiti i te rahinga whakaurunga o nga marere haumaru ki runga i te kohu. Ma te maataki koranu hanga-ake fehokotaki'anga, te mata hiri o te nohoanga takirere he ātete abrasion, ātete horo me te roa te ora ratonga.
  3. Ma te hanganga rapa waiariki, ka whakamahia e te kōpae takirere tona whakarereketanga iti mo te utu i raro i te kaha mahi reo hei whakapai ake i te kaha o te hiri me te hinga i te tukunga o mua o te paera haumaru ina tata te pehanga reo ki te pehanga tautuhinga. Na te hangarau tinei i mua, ko te mata hiri o te kōpae takirere he pai ake te pakeke, te aukati abrasion me te aukati waikura.
  4. Ko te painga o te mowhiti whakatikatika o runga ko te huri i te ahunga rere o te reo mai i te nohoanga takirere ki te huri i te kaha aukati o te reo i runga i te kōpae takirere. Ko te tuunga o te mowhiti whakatikatika o runga ka pa ki te paheketanga o te takirere.
  5. Ka hangaia he mokowā annular i waenga i te tihi o te mowhiti whakatikatika o raro me te papa o raro o te kōpae takirere. Ka hurihia te pehanga ma te whakarite i te rahinga mokowhiti o te mowhiti whakatikatika iti kia eke ki te pehanga whakatuwhera tika.
  6. Ko te kopiri o te puna ka whakatikahia e te nati whakahaere kia pai ai te tere me te tere o te pehanga tautuhinga.
  7. Ko te karekau whakatikatika pehanga tuara he tikanga awhina hei whakatika i te pehanga o te kōpae takirere. Ka taea te tiki mai i te pupuhi tika ma te whakatikatika i te karekau whakatika whakamuri; whakatika whakarunga ki te whakaheke i te pehanga whakamuri me te whakatika whakararo hei whakanui ake i te pehanga o muri.
  8. Ka whakatakotoria he hononga whakamahana ki waenga i te puna me te tinana takirere hei aukati i te puna mai i te awe o te mamaoa wera nui me te whakapumau i te elasticity o te puna.
  9. Ko te puna he waahanga nui hei whakatau i te mahi o te paera haumaru. Ko nga puna rereke kua hangaia mo nga pehanga rereke me nga pupuhi.
  10. Ka wehe te kaiwehe wera i te tinana takirere mai i te puna ki te whakaiti i te paanga o te wera ki te puna, te whakarite i te pakari o te puna me te mahi o te puna.
