Takirere SDV (Takirere Whakamutu)
✧ Whakaahuatanga
Ko te takirere SDV (Takirere Whakamutu) he takirere he pūwhera āhua-V kei tetahi taha o te pōro haurua-pōro. Mā te whakarerekē i te pūwhera o te pōro, ka whakarerekētia te horahanga whakawhiti-wāhanga o te rere reo hei whakarerekē i te rere. Ka taea hoki te whakamahi mō te whakahaere pana hei whakatutuki i te whakatuwheratanga, te katinga rānei o te paipa. He pānga horoi-ā-ia anō tōna, ka taea te whakatutuki i te whakarerekētanga rere iti i roto i te awhe whakatuwheratanga iti, he nui te ōwehenga whakarerekētanga, he pai mō te muka, ngā matūriki angiangi, me ngā mea paru.
Ko te wāhanga whakatuwheratanga me te kati o te takirere pōro momo-V he porowhita me te awa porowhita, ā, ko ngā tuakoi e rua e honoa ana e te pūtu, ka huri 90° hei whakatutuki i te kaupapa o te whakatuwheratanga me te kati.
He whānuitia te whakamahinga i roto i te pūnaha whakahaere aunoa o te hinu, te ahumahi matū me ētahi atu.

✧ Ngā Āhuatanga o te takirere SDV (Takirere Whakaweto) (putanga V)
1. He iti te ātete wai, he nui te tauwehenga rere, he teitei te ōwehenga whakarerekē. Ka taea te eke ki te :100:1, he nui ake tēnei i te ōwehenga whakarerekē o te takirere whakahaere kotahi-nohoanga tika, te takirere whakahaere rua-nohoanga me te takirere whakahaere ringaringa. He tata rite te ōrau o ōna āhuatanga rere.
2. hiri pono. Ko te taumata turuturu o te hanganga hiri mārō whakarewa ko te Akomanga IV o GB/T4213 "Pneumatic Control Valve". Ko te taumata turuturu o te hanganga hiri ngohengohe ko te Akomanga V, te Akomanga VI rānei o GB/T4213. Mō te hanganga hiri mārō, ka taea te hanga i te mata hiri matua pōro ki te whakakikorua chromium mārō, te mata ki te carbide sima cobalt, te rehu ki te paninga ātete-mau carbide tungsten, me ētahi atu, hei whakapai ake i te roa o te mahi o te hiri matua takirere.
3. tere te whakatuwhera me te kati. Ko te takirere pōro momo-V he takirere whiu koki, mai i te tuwhera katoa ki te kati katoa o te takai koki 90°, he taputapu hau piston AT ka taea te whakamahi mō ngā āhuatanga tapahi tere. I muri i te tāutanga o te tūnga takirere hiko, ka taea te whakarite kia rite ki te ōwehenga tohu anaro 4-20Ma.
4. He pai te mahi ārai. He āhua porowhita te porowhita, ā, he hanganga nohoanga kotahi te taha. Mēnā he matūriki totoka kei roto i te reo, kāore e puta he aukati kōhao pērā i ngā takirere pōro momo-O noa. Kāore he āputa i waenganui i te pōro āhua-V me te nohoanga, he nui te kaha kutikuti, he mea tino pai mō te whakahaere i te whakatārewatanga me ngā matūriki totoka kei roto he muka, he matūriki totoka iti rānei. Hei tāpiri, kei reira ngā takirere pōro āhua-V me te takai ao, he pai ake mō ngā āhuatanga pēhanga teitei, ā, ka taea te whakaiti i te rerekētanga o te matua pōro ina puta te rerekētanga pēhanga teitei. Ka whakamahia he hanganga hiri nohoanga kotahi, he hanganga hiri nohoanga takirua rānei. Ko te takirere pōro āhua-V me te hiri nohoanga takirua te nuinga o te wā e whakamahia ana mō te whakahaere rere reo ma, ā, ko te reo me ngā matūriki ka taea te whakararu i te kōhao waenga.
5. He hanganga pōro pumau te takirere pōro momo-V, he puna kei runga i te nohoanga, ā, ka taea te neke i te ara rere. Ka taea te utu aunoa i te kakahu o te pōro, te whakaroa i te roa o te ratonga. Kei roto i te puna he puna hexagonal, he puna ngaru, he puna kōpae, he puna kōpeketanga porotaka me ētahi atu. Mena he iti ngā poke o te reo, me tāpiri he mowhiti hiri ki te puna hei tiaki i a ia mai i ngā poke. Mō ngā takirere pōro-V hiri nohoanga rua, ka whakamahia te hanganga pōro mānu.
6. Mēnā he whakaritenga mō te ahi me te ārai-pūmau, he mea hanga te matua takirere ki te hanganga hiri mārō whakarewa, he mea hanga te whakakī ki te karāhe ngāwari me ētahi atu rauemi ātete pāmahana teitei, ā, he pakihiwi hiri te kakau takirere. Me whai i ngā mehua kawe hiko pūmau i waenga i te tinana takirere, te kakau me te porowhita. Me tutuki ki ngā whakaritenga hanganga ātete ahi a GB/T26479 me te ārai-pūmau a GB/T12237.
7. He rite te āhua o te takirere pōro āhua-V ki te hanganga hiri rerekē o te matua pōro, kāore he hanganga rerekē, kotahi te hanganga rerekē, rua te hanganga rerekē, toru ngā hanganga rerekē. Ko te hanganga e whakamahia whānuitia ana he kore rerekē. Ka taea e te hanganga rerekē te tuku tere i te pōro mai i te nohoanga ina whakatuwheratia, ka whakaiti i te kakahu o te mowhiti hiri me te whakaroa i te roa o te mahi. Ina kati, ka taea te whakaputa i te kaha rerekē hei whakarei ake i te pānga hiri.
8. Ko te aratau taraiwa o te takirere pōro momo-V he momo kakau, he momo tuku taputapu kutukutu, he hau, he hiko, he waipēhi, he hononga hiko-waipēhi me ētahi atu momo taraiwa.
E rua ngā huarahi hononga o te hononga takirere pōro momo-V, arā, te hononga flange me te hononga rawhi, arā, te hononga miro me te hononga hononga kōhao, te hononga papa me ētahi atu tikanga hononga.
10. He hanganga matua pōro āhua-V anō hoki tō te takirere pōro uku. He ātete pai ki te kakahu, engari he ātete hoki ki te waikura waikawa me te kawakore, he pai ake mō te whakahaere i ngā mea hanga ki te kirikiri. He hanganga matua pōro āhua-V anō hoki tō te takirere pōro kua whakakikoruatia ki te wheowhio, e whakamahia ana hei whakahaere me te whakahaere i ngā mea hanga waikawa me te kawakore. He whānui ake te whānuitanga o ngā tono mō te takirere pōro momo-V.
✧ Ratonga Whai Muri i te Hoko
He mea tino nui te ratonga muri-hoko o te takirere SDV (Takirere Whakaweto) (tauranga V), nā te mea ko te ratonga muri-hoko wā-tūturu me te whai hua anake ka taea te whakarite kia roa te mahi me te pumau. Ko ngā mea e whai ake nei ko ngā ihirangi ratonga muri-hoko o ētahi takirere pōro mānu:
1. Tāutanga me te whakatūnga: Ka haere ngā kaimahi ratonga muri-hoko ki te pae ki te tāuta me te patuiro i te takirere pōro mānu hei whakarite kia pumau, kia noa hoki tana mahi.
2. Tiaki: Me tiaki tonu te takirere pōro mānu kia pai ai te mahi, kia iti ai hoki te tere o te rahunga.
3. Te Whakatau Rapanga: Mena ka rahua te takirere pōro mānu, ka whakahaerehia e ngā kaimahi ratonga muri-hoko te whakatau raruraru i runga i te papaanga i roto i te wa poto rawa atu hei whakarite kia mahi noa.
4. Whakahoutanga me te whakapai ake i te hua: Hei whakautu ki ngā rauemi hou me ngā hangarau hou e puta ake ana i te mākete, ka tūtohu wawe ngā kaimahi ratonga muri-hoko i ngā otinga whakahou me te whakapai ake ki ngā kiritaki kia pai ake ai ngā hua takirere.
5. Whakangungu Mātauranga: Ka whakaratohia e ngā kaimahi ratonga muri-hoko he whakangungu mātauranga takirere ki ngā kaiwhakamahi hei whakapai ake i te taumata whakahaere me te tiaki o ngā kaiwhakamahi e whakamahi ana i ngā takirere pōro mānu. I roto i te poto, me whakamana te ratonga muri-hoko o te takirere pōro mānu i ngā taha katoa. Mā tēnei anake ka taea ai e ngā kaiwhakamahi te kawe mai i tētahi wheako pai ake me te haumaru hoko.
