Takirua Mono DBB Hiri Takirua Āmiomio Takirua Whānui Whānui
✧ Whakaahuatanga
Kei roto i te tinana takirere o tā mātou Takirere Whānui Whakawhanui Takirere Twin Seal DBB Plug, te tinana takirere, te kōpae takirere (kua whakauruhia ki roto i te mowhiti hiri matua), te uhi pito, te anga, te takai me ētahi atu wāhanga matua. Ko te matua takirere me te kōpae te matua o te wāhanga tinana takirere. Kei roto i te tinana takirere ngā hononga o runga me raro, kei waenganui te whakatuwheratanga o te awa rere, ā, he mata porotaka ngā taha e rua. He ara ārahi hiku-kōpiko kei te mira mata porotaka e piri ana ki ngā kōpae e rua i ngā taha e rua. Ko te kōpae te huānga hiri matua, ā, he mata porotaka tōna. Ka taea te whakatutuki i te tika o te hiri mārō Akomanga B. Ka mirahia te mata porotaka ki te porowhita awaawa, ā, ka whakauruhia te mowhiti hiri matua ki te rapa fluorine, ki te rapa nitrile rānei, me ētahi atu mā te whakahāngai me te whakamomona, e mahi ana i te mahi hiri mārō me te hiri ngohengohe ina kati te takirere.
Ko te DBB Plug Valve (plug takirua me te bleed plug valve) e kiia ana ko GENERAL VALVE, Twin Seal plug valve. Ka ārai i tēnei pakarutanga mau tonu mā te whakamahi i ngā reti nohoanga e rua e mau motuhake ana ki runga i te mono whakarara mā te whakamahi i ngā hiku kurupae, ka hoki whakamuri ā-mīhini mai i te mata nohoanga i mua i te hurihuri. Mā tēnei ka taea te whakamana i te hiri takirua e piri ana ki te mirumiru, me te kore e pakaru te hiri.
Ko te nuinga o te mea he tohu, he wira ringa, he pūwero porotaka, he pine pōro, he whāriki me ētahi atu wāhanga, e mau ana ki te taupoki pito, ā, e hono ana ki te tokotoko porowhita mā ngā pine hono. Ko te wāhanga whakahaere te kaiwhakaoho o te mahi. Katia te takirere mai i te tūranga tuwhera, hurihia te wira ringa ki te taha matau, ka huri te matua takirere 90° i te tuatahi, ā, ka panaia te kōpae takirere kia huri ki te tūranga awa rere o te tinana takirere. Kātahi ka neke te matua takirere ki raro i te rārangi tika, ka panaia te kōpae takirere kia whānui haere, ka whakatata atu ki te pakitara o roto o te takirere kia pēhia rā anō te hiri ngohengohe ki roto i te awaawa, kia pā ai te mata o te kōpae takirere ki te pakitara o roto o te takirere.
Whakatuwheratia te takirere mai i te tūranga kati, hurihia te wira ringa ki te taha maui, ka neke tika te matua o te takirere ki runga, kātahi ka huri 90° i muri i te taenga ki tētahi tūranga, kia noho ai te takirere i roto i te āhua kawe hiko.
✧ Ngā Āhuatanga o te Takirua Plug DBB Twin Seal Orbit Takirua Whānui Whakawhanui
1. I te wā e whakawhiti ana i te takirere, kāore te mata hiri o te tinana takirere e pā ki te mata hiri o te pereti reti, nō reira kāore he waku, he kakahu, he roa te ora ratonga o te takirere, ā, he iti te taipana whakawhiti;
2. Ina oti te whakatika i te takirere, kāore e hiahiatia kia tangohia te takirere mai i te paipa, wetewetehia noa te taupoki o raro o te takirere ka whakakapia he takirua kiriata, he tino watea mō te tiaki;
3. Kua whakaitihia te tinana takirere me te tikaokao, ka taea ai te whakaiti i te utu;
4. Kua whakakikoruatia te kōhao o roto o te tinana takirere ki te chromium mārō, ā, he mārō, he maeneene hoki te wāhi hiri;
5. He mea hanga te hiri rapa o te kiriata ki te rapa fluorine, ā, he mea whakairo ki te awaawa o te mata o te kiriata. Ko te hiri whakarewa ki te whakarewa me te mahi tiaki ahi ka whakamahia hei tuara o te hiri rapa;
6. He taputapu tuku aunoa tō te takirere (whiringa kore), e ārai ana i te pikinga pēhanga rerekē i roto i te rūma takirere, ā, e tirotiro ana i te pānga o te takirere i muri i te kati katoa o te takirere;
7. Ka tukutahi te tohu pana takirere ki te tūranga pana, ā, ka taea te whakaatu tika i te tūnga pana o te takirere.
