Kei te āwangawanga koe mō te whiriwhiri i te momo hononga hē mō ō takirere? Mā te miro kāore i te ōrite, te hononga ngoikore rānei ka puta he turuturu tonu, ka whakaroa i ngā kaupapa, ka kino hoki tō ingoa ngaio.
A takirere pōro mirohe takirere e whakamahi ana i ngā miro tīwiri i ōna pito hei hono atu ki tētahi paipa, ki tētahi hononga rānei. Mā tēnei hoahoa ka taea te tāuta me te tango ngāwari mā te whakamahi i ngā taputapu taketake, me te kore e hiahiatia he taputapu whakarewa motuhake, he taputapu whakapiri rānei. He maha ngā paerewa miro e wātea ana.
Ko tēnei hononga tīwiri māmā tētahi o ngā mea tino noa i te ao, engari ko ngā taipitopito te mea nui. Hei tangata kua whakatū i tētahi kamupene ki te whakarato i ngā otinga whakahaere wai o te ao, e mōhio ana ahau me tika te wāhanga māmā rawa. Mō tētahi kaiwhakahaere hoko pērā i a Carlos, mā te whakarato i te takirere miro tika ka taea e āna kiritaki te whakaoti tere me te pono i ā rātou mahi. He wāhanga nui tēnei o te hanga i tētahi kaupapa angitu me tētahi hononga pumau.
He rite tonu te NPT ki te miro?
Kei te whakaaro koe he rite katoa ngā miro? Mā te tono i tētahi takirere "miro" me te kore e tohua te paerewa ka taea te whiwhi i ngā wāhanga e kore e hono, ka nui te utu mō ngā whakahokinga me te whakaroa i ngā whakaroa mō ō kiritaki.
Kāo, ehara te NPT i te rite ki te miro; he mea motuhakemomoo te miro. Ko te "Miro" te kupu whānui mō te hononga tīwiri, ko te NPT ia (National Pipe Thread) he paerewa US mō ngā miro whakarara. Kei reira anō ētahi atu paerewa, pērā i te BSPT.
Kei te mahi tahi ahau me ngā hoa mahi i roto i ngā whenua neke atu i te 50, nō reira he wāhanga nui o taku mahi te whakahaere i ngā paerewa. He mea nui tēnei wehewehenga mō te hokohoko o te ao. Mena ka tono a Carlos i Mexico i tētahi takirere mō tētahi kaupapa e whakamahi ana i te paipa o Amerika, me hiahia ia ki te NPT. Mena kei te rapu ia mō tētahi kaupapa me ngā taputapu o Peretānia, tera pea me hiahia iaBSPTHe āhua ōrite rāua, engari kāore e hototahi. Mā te whakamahi i te mea hē ka hua ake he hononga e kore e hiri, e kino rānei ngā miro.
Te Mārama ki ngā Paerewa Miro Tino Noa
Ko te mōhio ki te rerekētanga te mea nui hei ārai i ngā rahunga hononga. Mō te nuinga o ngā tono i Amerika, ko te NPT te paerewa, engari he mea nui kia mōhio ki te huarahi kē atu.
| Āhuatanga | NPT (Miro Paipa ā-Motu) | BSPT (Paipa Paerewa o Peretānia) |
|---|---|---|
| Rohe | Te nuinga o Amerika Te Raki (USA, Canada, Mexico) | UK, Ūropi, Āhia, Ahitereiria |
| Koki Miro | 60 nekehanga | 55 nekehanga |
| Kōtaha | Ngā tihi me ngā awaawa papatahi | Ngā tihi me ngā awaawa porowhita |
| Hototahitanga | Kāore e hototahi ki te BSPT. | Kāore e hototahi ki te NPT. |
Ki a Carlos, mā te whakakī me te tapanga mārama i ngā takirere kia rite ki te paerewa miro (NPT, BSPT rānei) ka ārai i te whakapoauau mō āna kiritaki, ā, ka whakarite hoki kia whiwhi rātou i te wāhanga tika i te wā tuatahi.
He aha te takirere pōro NPT?
Kei te hiahiatia he takirere NPT i roto i tō whakatakotoranga kaupapa? Ki te kore koe e tino mōhio he aha te tikanga o tēnei mō te tāutanga, tera pea ka ngaro i a koe tētahi taahiraa nui, ā, ka mutu ka turuturu te hononga.
He takirere pōro noa iho te takirere pōro NPT i hangaia ki ngā miro paerewa NPT (National Pipe Thread). Mā te hoahoa whakarara o ēnei miro ka hangaia he hiri piri mā te piri tahi i te wā e whakakīia ana te takirere ki runga i tētahi paipa, i tētahi hononga rānei.
Ko te miro whakarara te āhuatanga matua i konei. Kāore i rite ki te miro tika i runga i te pūtu, ka whānui haere te miro NPT i a ia e haere ana. Ko te hoahoa o tēnei hoahoa he waihanga i tētahi urunga pokanoa, he pēhi i ngā miro kia hanga he hiri. Heoi, kāore tēnei hiri miihini i te tino tika. Kei te tohe tonu ahau kia mārama ō tātou hoa mahi ki tēnei: heMe whakamahi tonu he hiri miro mō te hononga NPTTērā pea tēneiRīpene PTFE (rīpene Teflon) he paipa wai rāneiKa whakakīia e te hiri ngā āputa iti i waenganui i ngā miro e kore e taea te kati e te kaha miihini. Ko te peke i tēnei taahiraa tētahi o ngā tino take o ngā turuturu i roto i ngā pūnaha miro. He taahiraa māmā tēnei e whakamana ana i te hua ngaio, ātete turuturu. He rerekē hoki ngā whirihoranga o ēnei takirere, pērā i ngā pito miro wahine e rua (te mea tino noa), me te pito tāne kotahi me te pito wahine kotahi mō ngā hiahia hononga motuhake.
Ka taea te tāpiri i ngā miro ki ngā paipa PVC?
Me hono atu rānei he takirere miro ki tētahi paipa PVC pito-noa? He hapa nui te ngana ki te tapahi tika i ngā miro ki roto i te paipa, ā, ka ngoikore, ka pakaru hoki.
Ae, ka taea e koe te tāpiri miro, engari me whakamahi koe i tētahi hononga urutau motuhake. Kaua rawa e tapahia tika ngā miro ki roto i te pakitara o te paipa PVC. Engari, me whakamahi koe i te sima whakarewa hei whakapiri i tētahi urutau PVC me ngā miro kua oti te whakapūtā ki te pito o te paipa noa.
I Pntek, ko te kounga me te haumaru ā mātou kaupapa matua. Mā te tapahi i ngā miro ki te pakitara o te paipa PVC, inā koa ko te Wāhanga 40, ka tangohia te rauemi, ka hangaia hoki ngā pūwāhi ahotea. Ka tino whakaitihia te pēhanga o te paipa, ā, ka tino tūpono ka pakaru, ka pakū rānei ina pēhia. Ko te tikanga tika me te tikanga ngaio ko te whakamahi i tētahiurutau.
Te Huarahi Tika hei Tāpiri Miro ki te PVC
- Kōwhiria te Pūurutau Tika:Kōwhiria he hononga urutau PVC. Mena e hiahia ana koe ki ngā miro tāne, whakamahia he "urutau tāne". Mena e hiahia ana koe ki ngā miro uwha, whakamahia he "urutau uwha". Ka whai miro tetahi pito, ā, ka waiho tetahi hei putanga maeneene.
- Te whakarite i te paipa me te hononga:Horoia te pito o te paipa PVC me te roto o te putanga o te urutau. Pania he paninga PVC ki ngā mata e rua.
- Tāpirihia te Sima Whakarewa:Pania he paparanga ōrite o te sima whakarewa PVC ki runga i te paninga tuatahi o te paipa me te hononga.
- Hono atu, ā, pupuri:Tōia tonutia te paipa ki roto i te putanga o te hononga me te nekehanga paku hurihuri. Puritia kia mau mō te 30 hēkona kia mārō ai te sima.
Mā tēnei ka hangaia he pūwāhi hononga miro kaha, pumau, kounga-nō-te-wheketere, me te kore e whakararu i te kounga o te paipa.
Me pēhea te hono i te PVC me te kore he miro?
Kei te rapu koe i tētahi atu huarahi hei whakakapi i ngā hononga miro mō tō pūnaha PVC? I ētahi wā, he pai ake te hononga tuturu, he mea whakarewa mō ngā tono motuhake.
Hei hono i te PVC me te kore he miro, ka whakamahia e koe he sima whakarewa me ngā hononga pūwero (he "paheke" rānei). He maeneene ngā pito o te takirere pōro pūwero hei urunga mō te paipa PVC ki roto. Ka pania e koe he paninga me te sima hei hanga i tētahi hononga pumau, he mea whakarewa matū, he tino kaha.
Ahakoa he pai ngā hononga miro mō te ngāwari o te mahi, he kaha ake ngā hononga whakarewa-whakarewa, ā, he iti ake ngā ara turuturu pea. I Pntek, ka tukuna e mātou he whānuitanga o ngā otinga nā te mea e mōhio ana mātou he rerekē ia mahi. Mō ngā whakaurunga pumau kāore e hiahiatia te tango i te takirere, hetakirere pūwerohe kōwhiringa pai rawa atu.
Te Whakataurite i ngā Momo Hononga PVC
Mō te kaiwhakahaere hoko pērā i a Carlos, mā te whai kōwhiringa rerekē ka taea e ia te whakatutuki pai ake i ngā hiahia o āna kiritaki. Anei tētahi whakamārama poto o ngā tikanga tino noa mō te tāuta i tētahi takirere pōro ki roto i tētahi raina PVC:
| Momo Hononga | Te Āhua o tana Mahi | Pai rawa atu mō | Painga Matua |
|---|---|---|---|
| Mirohia | Ka whiria ngā miro tāne me ngā miro uwha. | Ngā hononga e tika ana; te hono ki te whakarewa. | Ka taea te wetewete mō te whakatikatika, te whakakapi rānei. |
| Pūwero (Paheke) | Ka whakapirihia tika te paipa ki roto i ngā putunga o te takirere. | Ngā whakaurunga tuturu; te rere mōrahi. | Ka waihanga i tētahi here kaha, pumau, ā-kore e turuturu. |
| Kotahitanga Pono | Ka taea te tango i te tinana takirere; kua whakapirihia ngā hononga pito. | Ngā wāhi e hiahia ana kia tiakina; ngā hononga papu me te tātari. | Ka whakakotahi i te whakarewa tuturu me te tango ngāwari i te takirere. |
| He mea whakarara | Ka herea ngā pito o te hononga kia piri tahi. | Ngā paipa whānui nui (>4″); mō ngā whakamahinga ahumahi. | He tino kaha, he pai hoki mō te whakamahi i ngā mahi taumaha. |
TeTakirere pōro True Unionhe maha ngā wā ka pai rawa atu ngā āhuatanga e rua, e tuku ana i te haumarutanga o te whakarewa whakarewa me te ngāwari o te mahi o te takirere miro, o te takirere flanged rānei.
Whakamutunga
Ka whakamahia e te takirere pōro miro ngā miro tīwiri, pērā i te paerewa NPT, kia māmā ai te tāutanga. Hei hono atu ki te PVC, whakamahia tonu he urutau piri, whiriwhiria rānei hepūwero or takirere unianaengari.
