Kia ora tātou katoa!
Mena he maha āu mahi miihini poka, he maha āu pātai pēnei i: He aha te take e puta ai he poka 10.1mm i taku mata wiri 10mm? He aha rānei te take e ngawari ai te pakaru o aku mata wiri?
I te nuinga o ngā wā, ehara i te koretake o te pakeke o te mata wiri te raruraru, engari he oma radial whakamate e kore e kitea.
I roto i tēnei tuhinga, ka whakamāramahia e mātou he aha te runout me tōna hiranga i roto i ngā kupu māmā noa iho.
He aha te oma-kore?
I te poto, ko te oma e pā ana ki te wiri, te rūrū rānei o te mata wiri i te wā e hurihuri ana.
Whakaarohia he hurihanga tino tika. Ina huri te mata wiri i roto i te mīhini, me tino tika te rārangi pokapū ki te rārangi pokapū o te poupou mīhini. I tēnei wā, ka āhua tū tonu te mata wiri, ā, he tino pumau.
Heoi, ki te he te tūnga o te mata o te wiri, ki te kore rānei te pū o te mīhini e tika ana te pokapū, ka whai te pito o te wiri i tētahi ara porowhita i a ia e hurihuri ana. Ko te rahi o tēnei nekehanga wiri e kiia ana ko te oma.
He aha ngā ngoikoretanga o te runout?
Mō ngā wiri hurihuri maitai tere-rahi (HSS), he tino kino te rere nui. He maha ngā raruraru ka puta:
1. Ngā kōhao nui rawa (ngā kōhao kua whakanuia): Koinei te raruraru tino kitea. Nā te wiri o te wiri, ka tapahia he wāhi nui atu i tōna ake whānui.
2. Ngā pakitara poka taratara: Ka waruhia e te wiri wiri ngā pakitara o roto o te poka, ka hua ake he mata taratara. Tērā pea ka ngaro te porowhita o te poka, ka porowhita hoki.
3. Te roa o te wā e keri ana: Nā te kore taurite o te tohatoha o te kaha puta noa i ngā taha tapahi e rua nā te wiri ka nui rawa te mahi a tetahi taha, ka tere ake te mau, ka mangu hoki.
4. Te nui ake o te mōrearea o te pakaru o te keri: Ka puta he wiri nui mai i te rere o te pūwero. I te wā e keri ana i ngā kōhao hohonu, ka pakaru ngāwari te keri i tēnei wiri.
He aha te take e puta ai te oma?
Ehara i te mea nā te mata keri te he o te oma. He "raruraru pūnaha" te nuinga o te wā:
• Ngā raruraru o te taputapu mīhini, o te pūwero rānei: He paru tō pūwero i ngā maramara whakarewa? Kua kino te pakaru o te pūwero? Koinei te raruraru tino kitea. Mā te kore e tika te pupuri ka wiri te mata o te pūwero.
• Ngā take whakamau: Ka pūwero rawa te mata wiri, kāore rānei i te mau pai.
• Ko te mata wiri tonu: Ae, ko ētahi mata wiri kounga iti ka piko pea, ka huri rānei i ngā taha tapahi kia kore e ōrite te āhua. Ina koa, e rua ngā tukanga e hangaia ai ngā wiri hurihuri: te hurihuri me te huri. Ko te tikanga he pai ake te rere o ngā wiri whenua i ngā wiri hurihuri.
Me pēhea te whakatau?
E rua ngā tikanga matua hei whakatau i te rere o te wiri: he tirotiro tirohanga māmā me te ine tika. Ko te tirotiro tirohanga tino taketake ko te whakairi i te mata wiri me te huri i te tere puhoi, me te tirotiro i te pito o te wiri me ō kanohi kia rite te taumata. Mena he mārama, he pumau te pito o te wiri, he mea noa; mena ka puta he tirohanga takirua, he pōuri, he "porowhita hurihuri" rānei, he tohu tēnei kua nui te rere.
Ko tētahi tikanga tika ake ko te whakamahi i tētahi tohu mata (micrometer rānei): tuatahi, whakapirihia te mata wiri kia mau, kātahi ka whakanoho i te mata tohu ki te mata tapahi, ki te wāhi kakau maeneene rānei. Hurihia ā-ringa te porowhita kotahi te porowhita katoa, ka tuhia te rerekētanga i waenga i ngā uara mōrahi me ngā uara mōrahi e tohuhia ana e te tohu. Ko tēnei rerekētanga e tohu ana i te oma katoa o te tohu (TIR).
Tā mātou whakaaro
I te wā e hanga ana i ngā wiri miro maitai tere-rahi, he tino pakari ā mātou paerewa whakamātautau mō te tika o te tinana wiri me te ōrite o ngā taha tapahi, kia tino tika ai ngā paerewa o ia mata wiri i mua i te wehenga atu i tō mātou wheketere.
Me whiwhi hoki te hōiho pai i tētahi nohoanga pai. Hei whakatutuki i ngā hua keri tino pai, kia mahara ki te horoi me te tirotiro i tō pūwero taputapu mīhini i ia wā!
Mena he pātai āu i te wā e mahi ana koe i te mīhini, tēnā whakapā mai ki a mātou i ngā wā katoa.
