He whakamārama taipitopito mōte whārikingā momo kua whakarōpūtia e ngā āhuatanga whakamahinga

E ai ki ngā taiao mahi rerekē me ngā hiahia whakamahinga, ka taea te wehewehe i ngā peera ki ngā kāwai e whai ake nei:ngā peera pāmahana-tiketike, ngā peera pāmahana-iti, ngā peera ātete-waikura, ngā peera ātete-whanariki, ngā peera ā-aukume, ngā peera korehau, ngā peera whakahinuhinu-ake, ngā peera uku me ngā peera tere-tiketike.

 

1.Ngā peera pāmahana teitei

He pai mō ngā tono me ngā pāmahana whakahaere neke atu i te 120°C, ā, e whakamahia whānuitia ana i roto i ngā miihini aerojet, ngā tauhohenga ngota, ngā ngongo hihi-X, ngā taputapu hanga haurua-waenga, me ngā taputapu rewa, paninga me te whakakikorua hiko.

 

2. Ngā peera pāmahana iti

I hangaia mō ngā pāmahana tino iti i raro i te -60°C, pērā i ngā papu LNG, ngā papu hauota/hauwai wai, ngā papu butane, ngā taputapu whakatere wai i roto i ngā waka rererangi me ngā pere. Ko ngā hanganga noa ko ngā peera pōro awaawa hohonu rarangi kotahi me ngā peera roera porotaka.

 

3. Ngā peera ātete-waikura

E whakamahia ana i roto i ngā taiao haukū, waikura rānei, pērā i te wai moana, te mamaoa me ngā taiao waikawa-kawa. He mea hanga te nuinga ki ngā rauemi kowiri tira (pērā i te 9Cr18 me te 9Cr18Mo), ā, he maha ngā wā ka hangaia te whare herehere ki te 0Cr19Ni9, ki te parahi beryllium rānei; Ko te kowiri tira pāmahana-teitei pērā i te Cr14Mo4 e whakamahia ana i roto i ngā taiao pāmahana-teitei; Mō ngā peera nui, ko ngā kowiri tira martensitic (pērā i te 1Cr13 me te 2Cr13) he mea hanga te nuinga ki te maimoatanga nitriding mata.

 

4. Ngā peera ātete-whanariki

Mō te hauwai whanariki (H?S) o ngā taiao hau kino. He ngāwari te pakaru o te maitai whāriki noa nā te pakaru o te hauwai, te waikura hiko rānei, nō reira me whakamahi ngā whāriki rauemi motuhake i hangaia mai i ngā koranu nikara-konukōmiuma pērā i te 00Cr40Ni55A13, engari he iti ake tōna pakeke (51~55HRC), he iti noa te kaha whāriki, ā, me aro nui ki te kounga o te mata i te wā e whakamahia ana.

 

5. Ngā peera ārai-aukume

He mea hanga ki ngā rauemi kore-aukume, he iti rawa te uruhanga, ā, he pai mō te whakamahi i roto i ngā taiao he kaha ngā papa aukume. Ko te parahi beryllium (QBe2) he rauemi e whakamahia whānuitia ana, he kaha, he ngāwari, he ātete ki te kakahu me te ātete ki te waikura, ā, he whānuitia te whakamahinga i roto i te hau, te wai moana me ētahi atu taiao.

 

6. Whero korehau

E whakamahia ana i roto i te taiao korehau teitei (neke atu i te 1.33Pa te nekehanga korehau), ā, e whakamahia whānuitia ana i roto i ngā taputapu rererangi, ngā ngongo hihi-X, ngā aukume me ētahi atu whakamahinga. Ko te hanganga noa ko ngā peera pōro awaawa hohonu, ngā peera pōro whakapā koki rānei, he mea hanga pinepine ki ngā rauemi kowiri tira pērā i te maitai peera GCr15, 9Cr18 rānei, ā, ko ngā koranu hou pērā i te G60 e whakamahia ana i roto i ētahi wā korehau pēhanga teitei.

 

7. Ngā peera whakahinuhinu-ake

He tikanga whakahinuhinu kua hangaia ki roto, ā, kāore e hiahiatia he pūnaha whakahinuhinu o waho. Ko ngā hanganga noa ko ngā peera pōro whakapā koki kotahi te rarangi me ngā peera roera porotaka poto radial mō ngā taputapu he iti, he uaua rānei te tiaki i te whakahinuhinu.

 

8. Ngā peera uku

Ka urutau ki ngā āhuatanga mahi tino uaua, pērā i te tere tere, te pāmahana teitei, te pāmahana iti, te waikura kaha, te papa aukume kaha, te korehau me te taiao pēhanga teitei. He mea tino pai mō ngā tono tino pai nā te mea he kaha te kawe, he ātete wera pai, he tere mutunga teitei, he iti te waku, he roa te ora, he ātete waikura me te pai o te whakamarumaru hiko.

 

9. Ngā peera tere-teitei

He pai mō ngā uara Dm·n e neke atu ana i te 1.0×10 mm·r/min (ko Dm te diameter toharite o te huānga hurihuri, ko n te tere o te mowhiti o roto). I tēnei wā, kua neke atu te uara i te 3.0×10, ā, kua eke ki te 3.5×10, e whakamahia whānuitia ana i roto i ngā taputapu mīhini tere-rahi, te rererangi me ngā taputapu tika.
