He aha te peera hiato

Ko ngā peera he mea hanga mai i ngā wāhanga rerekē (ngā konganuku, ngā kirihou, ngā rauemi hinu totoka) ka kiia he peera hiato, he peera noa iho ēnei, ā, ko ngā peera hiato, e mōhiotia ana ko ngā pūkaha, ngā papa, ngā peera ringaringa rānei, he porotaka te nuinga, ā, kāore he wāhanga e neke ana.

 

Kei roto i ngā whirihoranga paerewa ngā peera porotaka mō ngā kawenga radial, ngā peera flange mō ngā kawenga radial me ngā kawenga axial māmā, ngā whakawātea me ngā gaskets hurihuri mō ngā kawenga axial taumaha, me ngā pereti reti o ngā āhua rerekē. Kei te wātea hoki ngā hoahoa ritenga, tae atu ki ngā āhua motuhake, ngā āhuatanga (puna, ngā kōhao, ngā kokoru, ngā ripa, me ētahi atu) me ngā rahi.

 

Ngā peera hiatoe whakamahia ana mō te nekehanga reti, te hurihuri, te wiri, te hurihanga rānei. Ko ngā tono papatahi he mea whakamahi noa hei peera papatahi, hei whakakī peera, hei pereti kakahu. He papatahi te nuinga o ngā mata reti, engari ka taea hoki te porotaka, ā, ka neke tonu i te rārangi tika, ehara i te nekehanga hurihuri. Ko ngā tono hurihuri he mata porotaka me te kotahi, e rua rānei ngā ahunga haere. Ko ngā tono nekehanga wiri me te hurihanga he mata papatahi, porotaka rānei e haere ana i ngā ahunga e rua.

 

Ka taea te hanga o te peera hiato he totoka, he papa wehe rānei (peera takai) kia māmā ai te tāutanga. He mea nui te whakataurite i te peera ki te tono. Ko ngā kawenga teitei me whai peera me te horahanga pa nui ake me te kaha kawe kawenga teitei. Kua hangaia ngā peera hinu totoka kia mahi i ngā pāmahana teitei ake i ngā peera hinu whakahinuhinu me te hinu. Ko ngā tono pāmahana teitei me whai tikanga whakahinuhinu motuhake hei whakaiti i te hanga wera me te waku.

 

Ngā peera hiatohe rerekē ngā hanganga e hangaia ana. Ko te kōwhiringa o te hua e whakawhirinaki ana ki ngā āhuatanga whakahaere me ngā whakaritenga mahi.

 

Ngā momo rauemi peera waku-iti

 

Ko ngā peera whakarewa he mea hanga ki te paparanga whakarewa (ko te tikanga he rino, he parahi rānei) e pania ana ki te paparanga parahi porous, e whakakīia ana ki te PTFE me ngā tāpiringa hei hanga i tētahi mata rere me ngā āhuatanga peera ātete-waku me te kakahu teitei. Ka taea te whakahaere i ēnei peera mā te whakamaroke, mā te whakahinuhinu rānei ki waho.

 

Ka taea hoki te hanga i ngā peera hiato ki ngā kirihou hangarau, he tino ātete ki te kakahu me te iti o ngā āhuatanga waku, ā, e whakamahia whānuitia ana i roto i ngā āhuatanga mahi waku maroke me te whakahinuhinu. He mea whakarewa werohanga, ka taea te hoahoa ki te nuinga o ngā āhua, ā, he mea hanga mai i ngā momo kapia i konatunatua ki ngā muka whakakaha me ngā hinu whakahinuhinu totoka. He tino pai te pumau o ngā āhuatanga o ēnei peera, he iti te tauwehenga waku, ā, he pai te kawe wera.

 

Ko ngā peera hiato kua whakapakarihia ki te muka tētahi atu momo peera hiato, he mea hanga mai i ngā arai peera takai-miro, kua whakakiia ki te muka karāhe, ātete-mau epoxy, iti-waku me ngā momo paparanga. Mā tēnei hanganga ka taea e te peera te tu atu ki ngā kawenga pūmau me ngā kawenga hihiri teitei, ā, nā te koretake o te rauemi he mea pai mō te whakamahi i roto i ngā taiao waikura.

 

Ko ngā peera parahi whakakotahi monometal, bimetal, me te sintered he mea hanga mō te whakamahi i ngā tono ahumahi whenua me raro i te wai, ka neke haere mārire i raro i ngā kawenga teitei. Ko ngā peera parahi totoka kua whakakiia ki te hinu whakahinuhinu ka whakarato i te mahi kore tiaki i roto i ngā tono pāmahana teitei, ko ngā peera mono- me te bimetal he mea hanga mō ngā tono whakahinuhinu.

 

Ko te rerekētanga i waenganui ingā peera hiatomengā peera hurihuri me ngā peera ngira

 

He rerekētanga nui i waenga i ngā peera hiato me ngā peera hurihuri, nō reira kāore e taea te whakawhiti.

 

1. Nā te hoahoa matatini, te hanganga tika, me te tāutanga tika o ngā peera hurihuri, he nui ake te utu i ngā peera hiato.

2. He pai ake ngā peera hurihuri mō ngā tono e hiahia ana ki te tūranga tika o te pou, me/ranei te iti o te waku.

3. Nā te nui ake o te horahanga pā me te ngāwari ki te urutau, ka taea e ngā peera hiato te whakarato i te kaha kawe kawenga teitei ake me te ātete ki ngā kawenga pānga nui me ngā kawenga kukū i ngā pito.

4. He pai ake te whakatikatika a ngā peera hiato mō te hē o te tūnga i ētahi peera hurihuri hei whakaiti i te pānga o te kawenga kukū i te pito.

5. He hoahoa tino angiangi te peera hiato, ka taea te whakaiti i te rahi o te anga, te penapena wāhi me te taumaha ki te whānuitanga nui.

6. He kaha ake te ātete o te peera hiato ki te nekehanga tauutuutu, ka taea ai te whakaroa i te ora o te peera.

7. Kāore te peera hiato e pakaru i te kakahu i puta mai i te paheke o ngā huānga hurihuri ina oma ana i te tere tiketike me te kawenga iti rawa, ā, he tino pai te mahi whakamātao.

8. Ki te whakaritea ki ngā peera hurihuri, kāore he wāhanga neke o roto o ngā peera hiato, nō reira he mārie ake te oma, ā, kāore he rohe tere i raro i te pūnaha kua whakahinuhinuhia tika.

9. He māmā noa te tāutanga o ngā peera hiato, ko te anga miihini anake e hiahiatia ana, ā, e kore e kino ngā taputapu ki te whakataurite ki ngā peera hurihuri.

10. Ki te whakaritea ki ngā peera hurihuri paerewa, he kaha ake te ātete o ngā peera hiato kore-whakarewa ki te waikura.

11. Ka taea te whakamaroke i te peera hiato me te kore he utu mo te pūnaha hinu whakahinuhinu tāpiri, te hinu whakahinuhinu me te wā kore mahi o ngā taputapu i te wā tiaki.

12. Ka taea te whakahaere maroke i te peera hiato i raro i te pāmahana tiketike me ngā poke.
