He wāhanga nui te hiri o te takirere katoa, ko tōna kaupapa matua he ārai i te turuturu,te takirereKo te nohoanga hiri e kiia ana hoki ko te mowhiti hiri, he whakahaere e pā tika ana ki te reo i roto i te paipa, e ārai ana i te rere o te reo. Ina whakamahia te takirere, he maha ngā momo reo i roto i te paipa, pērā i te wai, te hau, te hinu, te waikura, me ētahi atu, ā, ka whakamahia ngā hiri o ngā takirere rerekē ki ngā wāhi rerekē, ā, ka taea te urutau ki ngā momo reo.
TWSVarae whakamahara ana tēnei ki a koe ka taea te wehewehe i ngā rauemi o ngā hiri takirere ki ngā wāhanga e rua, arā, ko ngā rauemi whakarewa me ngā rauemi kore-whakarewa. Ko ngā hiri kore-whakarewa e whakamahia whānuitia ana i roto i ngā paipa i te pāmahana me te pēhanga noa, ko ngā hiri whakarewa ia he whānui ake ngā whakamahinga, ā, ka taea te whakamahi i ngā pāmahana teitei. te pēhanga teitei.
1. rapa hangai
He pai ake te rapa hangai i te rapa tūturu i runga i te ātete ki te hinu, te ātete ki te pāmahana me te ātete ki te waikura. Ko te pāmahana whakahaere o te rapa hangai he t≤150°C, ko te rapa maori he t≤60°C, ā, ka whakamahia te rapa mō te hiri i ngā takirere porowhita, ngā takirere kuaha, ngā takirere diaphragm, ngā takirere pūrerehua, ngā takirere tirotiro, ngā takirere pītiti me ētahi atu takirere me te pēhanga PN noa≤1MPa.
2. Nairona
He iti te tauwehenga waku o te nairona, ā, he pai te ātete ki te waikura. Ko te nairona te mea e whakamahia ana mō ngā takirere pōro me ngā takirere porowhita me te pāmahana t≤90°C me te pēhanga ingoa PN≤32MPa.
Ko te PTFE te nuinga e whakamahia ana mō ngā takirere porowhita, ngā takirere kuaha, ngā takirere pōro, me ētahi atu me te pāmahana t≤232°C me te pēhanga ingoa PN≤6.4MPa.
4. Rino maka
Ka whakamahia te rino maka mō ngā takirere kuaha, ngā takirere porowhita, ngā takirere mono, me ētahi atu mō te pāmahana.≤100°C, pēhanga ingoa PN≤1.6MPa, te hau me te hinu.
5. Koranu Babbitt
E whakamahia ana te koranu Babbitt mō te takirere porowhita haukini me te pāmahana t-70 ~ 150℃me te pēhanga ingoa PN≤2.5MPa.
6. Parahi koranu
Ko ngā rauemi e whakamahia whānuitia ana mō ngā koranu parahi ko te parahi tine 6-6-3 me te parahi manganese 58-2-2. He pai te ātete ki te kakahu o te koranu parahi, ā, he pai mō te wai me te mamaoa me te pāmahana teitei.≤200℃me te pēhanga ingoa PN≤1.6MPa. He maha ngā wā e whakamahia ana i roto i ngā takirere kuaha, ngā takirere porowhita, ngā takirere tirotiro, ngā takirere mono, me ētahi atu.
7. Kowiri tira Chrome
Ko ngā momo maitai kowiri tira chromium e whakamahia whānuitia ana ko te 2Cr13 me te 3Cr13, kua tineia, kua whakamahanatia hoki, ā, he pai te ātete ki te waikura. He maha ngā wā ka whakamahia ki ngā takirere wai, mamaoa me te hinu me te pāmahana t≤450℃me te pēhanga ingoa PN≤32MPa.
8. Kowiri tira Chrome-nickel-titanium
Ko te momo maitai kowiri tira chromium-nickel-titanium e whakamahia whānuitia ana ko te 1Cr18Ni9ti, he pai te ātete ki te waikura, te horo me te wera. He pai mō te mamaoa me ētahi atu mea he pāmahana teitei.≤600°C me te pēhanga ingoa PN≤6.4MPa, ā, e whakamahia ana mō ngā takirere porowhita, ngā takirere pōro, me ētahi atu.
9. Te whakarewa i te maitai
Ko te momo maitai nitriding e whakamahia whānuitia ana ko te 38CrMoAlA, he pai te ātete ki te waikura me te rakuraku i muri i te maimoatanga waro. He maha te whakamahinga i roto i ngā takirere keti teihana hiko me te pāmahana t≤540℃me te pēhanga ingoa PN≤10MPa.
10. Te whakapōronitanga
Ka tukatuka tika te whakapūkara i te mata hiri mai i te rauemi o te tinana takirere, o te tinana kōpae rānei, kātahi ka mahi i te maimoatanga mata whakapūkara. He pai te ātete ki te pakaru o te mata hiri. Mō te takirere pupuhi o te teihana hiko.
Ina whakamahia te takirere, ko ngā mea hei aro atu ko ēnei e whai ake nei:
1. Me whakamātau te mahi hiri o te takirere kia tino tika ai tana mahi.
2. Tirohia mēnā kua tawhito te mata hiri o te takirere, ā, whakatikahia, whakakapia rānei kia rite ki te āhuatanga.
