I tēnei rā, ka whakamāramahia e te ētita te huarahi hei whakatika i ngā hapa noa o ngā takirere whakahaere. Kia tirohia!

Ko ēhea ngā wāhanga me tirotiro ina puta he hapa?

1. Te pakitara o roto o te tinana takirere

He maha ngā wā ka pāngia, ka waikura hoki te pakitara o roto o te tinana takirere e te reo ina whakamahia ngā takirere whakahaere i roto i ngā tautuhinga pāpāho rerekētanga pēhanga teitei me te waikura, nō reira he mea nui kia aro ki te aromatawai i tōna ātete ki te waikura me te pēhanga.

2. Nohoanga takirere

Ka tere te waikura o te mata o roto o te miro e mau ana i te nohoanga takirere ina mahi ana te takirere whakahaere, ā, ka wetekina te nohoanga takirere. Nā te urunga o te reo tēnei. I te wā e tirotirohia ana, kia maumahara ki tēnei. Me tirotirohia te mata hiri o te nohoanga takirere mō te kino i te wā e mahi ana te takirere i raro i ngā rerekētanga pēhanga nui.

3. Pōro

Ko te takirere whakahaereko te wāhanga nekeneke i te wā e mahi ana ka kiia ko tematua takirereKoinei te mea i tino pakaru, i tino memeha hoki i te pāpāho. Me tirotirohia te pakaru me te waikura o ia wāhanga o te matua takirere i te wā tiaki. Me mōhio ko te pakaru o te matua takirere (cavitation) ka nui ake te kino ina nui te rerekētanga pēhanga. Me whakatika te matua takirere mēnā he tino pakaru. Hei tāpiri, me mahara koe ki ngā āhuatanga rite ki te kakau takirere me ngā hononga korekore ki te matua takirere.

4. Ngā mowhiti "O" me ētahi atu gaskets

Ahakoa kua koroheke, kua pakaru rānei.

5. Te tākai PTFE, te hiri hinu

Ahakoa kua tawhito, kua pakaru rānei te mata e hono ana, me whakakapi mēnā e tika ana.

Ka haruru te takirere whakahaere, me aha ahau?

1. Whakakorehia te haruru orooro

Kāore te pūngao e taupokina kia pāorooro rā anō te takirere whakahaere, ka puta he haruru nui atu i te 100 dB. Ko ētahi he iti te haruru engari he kaha te wiri, ko ētahi he haruru nui engari he ngoikore te wiri, ko ētahi he haruru me te wiri nui.

Ko ngā oro kotahi-oro, i te nuinga o te wā i waenga i te 3000 me te 7000 Hz, ka puta mai i tēnei haruru. Heoi anō, ka memeha noa te haruru mēnā ka tangohia te haruru.

2. Whakakorehia te haruru cavitation

Ko te take matua o te haruru waiora ko te cavitation. Ka puta te kaha o te aueue ā-rohe me te haruru cavitation i te pānga tere-nui e puta ana ina hinga ngā mirumiru i te wā o te cavitation.

He whānui te awhe auau o tēnei haruru, ā, he haruru e rite ana ki ngā wai kei roto he kirikiri me te onepu. Ko tētahi tikanga whai hua hei whakakore me te whakaiti i te haruru ko te whakaiti i te pokanga.

3. Whakamahia ngā paipa matotoru te pakitara

Ko tētahi huarahi hei whakatika i te ara oro ko te whakamahi i ngā paipa he pakitara pakari. Mā te whakamahi i ngā paipa matotoru ka taea te whakaiti i te haruru mā te 0 ki te 20 tekipere, ko ngā paipa angiangi ka taea te whakanui ake i te haruru mā te 5 tekipere. Ko te kaha ake o te pānga whakaiti haruru, ko te matotoru ake o te pakitara paipa he rite te whānui o te paipa, ā, ko te nui ake o te whānui o te paipa he rite te matotoru o te pakitara.

Hei tauira, ko te nui o te whakaiti haruru ka taea te -3.5, -2 (arā, te pikinga), 0, 3, me te 6 ina ko te matotoru o te pakitara o te paipa DN200 he 6.25, 6.75, 8, 10, 12.5, 15, 18, 20, me te 21.5mm, ia. 12, 13, 14, me te 14.5 dB. Heoi anō, ka piki ake te utu me te matotoru o te pakitara.

4. Whakamahia ngā rauemi mimiti-oro

Koinei hoki te huarahi tino rongonui, tino whai hua hoki ki te tukatuka i ngā ara oro. Ka taea te takai i ngā paipa ki ngā rauemi e mimiti ana i te oro i muri i ngā takirere me ngā pūtake oro.

He mea nui kia maumahara he tawhiti rawa te rere o te haruru i roto i te rere o te wai, nō reira, mā te whakamahi i ngā paipa matotoru he pakitara, mā te takai rānei i te rauemi mimiti haruru, e kore e tino whakakorea te haruru.

Nā te nui o te utu, he pai rawa atu tēnei huarahi mō ngā āhuatanga he iti te haruru, he poto hoki te roa o ngā paipa.

5. Pūwero raupapa

Ka taea te whakakore i te haruru ā-rangi mā te whakamahi i tēnei tikanga. Kei a ia te kaha ki te whakaiti i te taumata haruru e tukuna ana ki te paparanga ārai totoka, me te whakakore i te haruru i roto i te wai. Ko ngā rohe rere nui, ngā rohe hekenga pēhanga teitei rānei i mua me muri i te takirere, koia te mea tino pai mō te ōhanga me te whai huatanga o tēnei tikanga.

He huarahi whai hua ngā whakangāwari oro mimiti-roto hei whakaiti i te haruru. Ahakoa rā, ko te whakaiti i te haruru ka herea ki te 25 dB pea nā runga i ngā āhuatanga utu.

6. Pouaka ātete oro

Whakamahia ngā pouaka, ngā whare me ngā whare ātete-oro hei wehe i ngā pūtake haruru o roto, hei whakaiti hoki i te haruru o te taiao o waho ki tētahi awhe e tika ana.

7. Te whakawhāiti raupapa

Ka whakamahia te huarahi whakawhāiti raupapa ina teitei te pēhanga o te takirere whakahaere (△P/P1≥0.8). Ko te tikanga o tēnei ka tohatohahia te hekenga pēhanga katoa i waenga i te takirere whakahaere me te wāhanga whakawhāiti pumau i muri i te takirere. Ko ngā huarahi pai ki te whakaiti i te haruru ko ngā pereti whakawhāiti rere porous, ngā diffuser, me ētahi atu.

Me hanga te kaiwhakarara hau kia rite ki te hoahoa (te āhua ā-tinana, te rahi) kia tino whai hua ai te kaiwhakarara hau.
