1. Tāpirihia te hinu hiri

Mō ngā takirere kāore e whakamahi ana i te hinu hiri, whakaarohia te tāpiri hinu hiri hei whakapai ake i te mahi hiri o te kakau takirere.

2. Tāpirihia he whakakī

Hei whakapai ake i te mahi hiri o te takai ki te kakau takirere, ka taea te whakamahi i te tikanga tāpiri takai. I te nuinga o te wā, ka whakamahia ngā whakakī whakauru paparua, paparua rānei. Kāore e kitea he hua mēnā ka whakanuia noa te rahinga, pērā i te whakanui ake i te maha mai i te 3 ki te 5.

3. Whakakapia te whakakī karāpeti

Ko te pāmahana whakahaere o te takai PTFE e whakamahia whānuitia ana kei waenga i te -20 ki te +200°C. Ina tino rerekē te pāmahana i waenga i ngā rohe o runga me raro, ka tino heke te mahi hiri, ka tere te tawhito, ā, ka poto te ora.

Ka wikitoriahia ēnei ngoikoretanga e ngā whakakī karāhe ngāwari, ā, he roa te ora mahi. Nō reira, kua hurihia e ētahi wheketere ngā takai PTFE katoa ki te takai karāhe, ā, kua whakamahia ngā takirere whakahaere hou i muri i te whakakapinga o te takai PTFE ki te takai karāhe. Heoi, he nui te hysteresis o te whakamahi i te whakakī karāhe, ā, i ētahi wā ka puta te ngokingoki i te tuatahi, nō reira me whai whakaaro ki tēnei.

4. Hurihia te ahunga rere, ka whakanoho i te P2 ki te pito o te kakau takirere.

Ina nui te △P, ā, he nui te P1, he uaua ake te hiri i te P1 i te hiri i te P2. Nō reira, ka taea te whakarerekē i te ahunga rere mai i te P1 i te pito o te kakau takirere ki te P2 i te pito o te kakau takirere, he pai ake tēnei mō ngā takirere he nui te pēhanga me te rerekētanga pēhanga nui. Hei tauira, me whakaaro ngā takirere pupuhi ki te hiri i te P2.

5. Whakamahia te hiri o te gasket arotahi

Mō te hiri i ngā taupoki o runga me raro, te hiri i te nohoanga takirere me ngā tinana takirere o runga me raro. Mena he hiri papatahi, i raro i te pāmahana teitei me te pēhanga teitei, he ngoikore te mahi hiri, ka puta he turuturu. Ka taea e koe te whakamahi i te hiri hiri arotahi hei utu, ka taea ai te whakatutuki i ngā hua pai.

6. Whakakapia te hiri hiri

Tae noa ki tēnei wā, kei te whakamahia tonutia ngā papa asbestos i te nuinga o ngā hiri. I ngā pāmahana teitei, he ngoikore te mahi hiri, ā, he poto te roa o te mahi, ka puta he turuturu. I tēnei wā, ka taea e koe te whakamahi i ngā hiri porowhita, ngā mowhiti "O", me ētahi atu, kua whakamahia nei e te tini o ngā wheketere.

7. Whakakīia ngā pūtu kia ōrite te āhua, ka hiritia ki ngā gasket angiangi

I roto i te hanganga takirere whakahaere me te hiri mowhiti "O", ina whakamahia ngā gasket matotoru me te nui o te whakarerekētanga (pērā i ngā pepa takai), ki te kore e ōrite te pēhanga, ā, he kore ōrite te kaha, ka ngawari te pakaru, te piko me te whakarerekē i te hiri. He tino pā ki te mahi hiri.

Nō reira, i te wā e whakatika ana, e huihui ana hoki i tēnei momo takirere, me whakakīkī ngā pūtu pēhi kia ōrite te āhua (kia mōhio koe kāore e taea te whakakīkī tonu). He pai ake mēnā ka taea te huri i te gasket matotoru ki te gasket angiangi, ka taea ai te whakaiti i te piko me te whakarite i te hiri.

8. Whakanuia te whānui o te mata hiri

Kāore he mata piko ārahi me te mata ārahi o te matua takirere papatahi (pērā i te mono takirere o te takirere tūnga-rua me te takirere ringaringa) i roto i te nohoanga takirere. Ina mahi te takirere, ka pāngia te matua takirere e te kaha taha, ka rere atu i te ahunga rere mai. Ki te tapawhā, ka nui ake te āputa ōrite o te matua takirere, ka nui ake te kino o tēnei āhuatanga taha. Hei tāpiri, ko te whakarerekētanga, te kore-pokapū, te iti rānei o te porowhita o te mata hiri o te matua takirere (ko te nuinga o te wā ko te porowhita 30° hei ārahi) ka hua ake he hiri matua takirere ina tata ki te kati. Ka whakatakotoria te mata pito porowhita ki runga i te mata hiri o te nohoanga takirere, ka peke te matua takirere i te wā e kati ana, ka kore rānei e kati, ka nui ake te turuturu o te takirere.

Ko te otinga māmā rawa atu, ko te whakanui ake i te rahi o te mata hiri o te matua takirere, kia 1 ki te 5 mm te iti iho o te diameter o te mata pito o te matua takirere i te diameter o te nohoanga takirere, ā, kia rawaka te arataki hei whakarite kia arahina te matua takirere ki roto i te nohoanga takirere, kia mau tonu ai te pa atu o te mata hiri.
