Ngā kohua kowiri tirahe mea nui ki te kīhini, engari i roto i te wā,ngā kakau o ngā taputapu tunu kai ka taea te wetekina, te wehe rānei nā te wera, te kakahu, te takahanga tūpono rānei. Ehara i te mea he whakarihariha noa te kakau wiri - he mōrearea haumaru hoki. Waimarie, he māmā ake te tāpiri anō i te kakau kohua kowiri tira i tō whakaaro! I roto i tēnei aratohu, ka ārahi mātou i a koe i roto i tengā tikanga pai rawa atuhei whakamau mau, ahakoa kei te whakamahi koe i ngā tīwiri, i ngā rivet, i ngā wai whakapiri rānei.
He aha i wetekina ai ngā kakau o ngā kohua kowiri tira?
I mua i te ruku ki ngā whakatikatika, kia mārama ki ngā take noa:
- Te weraweraKa ngoikore ngā hononga whakarewa i te whakamahana/whakamatao tonu.
- Ngā tīwiri/ngā rivet wetekina: Ka pakaru pea ngā here o ngā hononga i te whakamahinga o ia rā.
- Te kino o te pāngaKi te taka te kohua, ka piko, ka whati rānei te kakau.
Mā te mōhio ki te take ka āwhina i a koe ki te whiriwhiri i te tikanga whakatika tika!
Ngā Utauta me ngā Rauemi e Hiahiatia ana e Koe
- tīwiri (he mata papatahi, he tīwiri Phillips rānei, kei te āhua o tō kohua)
- Ngā tīwiri/rivet whakakapinga (tirohia te rahi me te rauemi)
- He piripiri epoxy pāmahana teitei, he piripiri whakarewa rānei (hei tauira, JB Weld)
- He pū rākau, he pū rivet rānei
- Ngā karapu haumaru me ngā mōhiti kanohi
Tikanga 1: Te Whakakī, te Whakakapi rānei i ngā Wiri
Ko te nuinga o ngā kohua maitai kore waikura he whakamahi i ngā tīwiri hei whakapiri i ngā kakau. Anei me pēhea te whakatika:
- Tirohia te kakauKimihia ngā tīwiri (e huna ana i raro i tengā taupoki silicone).
- Whakakīkīhia ngā tīwiriWhakamahia he tīwiri hei whakau i ngā tīwiri wetekina. Kaua e whakakī rawa kia kore ai e tangohia.
- Whakakapia ngā tīwiri kua pakaruMena kua tangohia ngā tīwiri, kua waikura rānei, whakawhitia ki te maitai kore waikura, ki ētahi atu mea rānei e ātete ana ki te wera.
Tohutohu NgaioTāpirihia he pata o te miro-maukati (hei tauira, Loctite) hei ārai i te wetewete a muri ake nei.
Tikanga 2: Te Whakahou i te Rīpene
He maha ngā kohua arumoni e whakamahi ana i ngā rivet kia maeneene ai te āhua. Me nui ake te kaha ki te whakarivet anō engari ka roa te mau:
- Werohia ngā rivets tawhitoWhakamahia he mata wiri he nui ake i te pane o te rivet.
- Whakauruhia ngā rivet houWhakahāngaihia te kakau me te kohua, kātahi ka whakau ki ngā rivet kowiri tira.
- Whakamaua ki te pū rivetPēhia te rivet kia piri rawa.
TuhipokaHe pai ake te ātete o ngā rivet kowiri tira ki te waikura me te wera i te konumohe.
Tikanga 3: Te Whakamahi i te Epoxy Mahana-Tiketike
Mena kāore e taea te whakamahi i ngā tīwiri, i ngā rivet rānei (hei tauira, ngā miro whati), ka taea te whakamahi i tētahi kāpia kaha:
- Horoia ngā mataTangohia te hinu me ngā paru ki te waipiro mirimiri.
- Ranunga epoxyWhāia ngā tohutohu mō te hua (hei tauira, me rite ngā wāhanga o te JB Weld).
- Tāpirihia he piripiriHorahia he paparanga angiangi ki te kakau me te kohua.
- Piri me te whakaora: Puritia teKakau kowiri tirakia pūmau mō te 15–30 meneti, kātahi ka waiho kia māro mō ngā haora 24.
WhakatūpatoKaua e whakamahia te kohua kia maroke rawa te piripiri.
Ngā Tohutohu Haumaru mō ngā Whakatikatika Kakau
- Me mau tonu ngā karapu me ngā tiaki kanohi i te wā e keri ana, e pā ana rānei ki ngā piripiri.
- Whakamātauria te kaha o te kakau i mua i te whakamahinga o te kohua mō te tunu kai.
- Āta karohia ngā piripiri utu iti—whiriwhiria ngā waitohu kua tohua mō500°F+ngā pāmahana.
Ngā Pātai Auau
Q: Ka taea e au te whakapiri i te kakau o te kohua ki te piri piri?
A: Kāore te piripiri wera noa e ātete ki te wera. Whakamahia he epoxy pāmahana teitei hei whakakapi.
P: Me pēhea taku mōhio mēnā kua whakakīia, kua whiria rānei te kakau o taku kohua?
A: Tirohia mēnā he upoko tīwiri e kitea ana (i raro i ngā taupoki silicone) he rivet maeneene, rite ki te pātene rānei.
Q: Me whakatika, me whakakapi rānei te kohua?
A: Mena kua pakaru te kohua (hei tauira, kua piko te turanga), whakaarohia te whakakapi kia haumaru ai.
