Me whakakanapa te peita i runga i te paipa mā te whakamahi i te rawhi o te mita rere ultrasonic?

Kua hangaia ngā mita rere ultrasonic-whakapiripiri hei ine i te rere kāore e pokanoa, arā, ka whakairihia ki waho i te pakitara o waho o te paipa me te kore e hiahiatia kia tapahia ki roto i te paipa, kia pā tika rānei ki te wai o roto. Ko te hiahia kia whakakanapahia te paipa, ka whakawhirinaki ki ētahi āhuatanga e pā ana ki te āhua o te mata o te paipa me te kaha o te mita ki te tuku me te whiwhi tohu ultrasonic. Anei tētahi whakamārama taipitopito:

Kāore e hiahiatia ana te whakakanapa i te nuinga o te wā

• He paipa hou, he paipa kua paku tawhito rānei, he iti noa ngā āhua rerekē o te mata (hei tauira, he paipa whakarewa maeneene, he paipa PVC, he paipa HDPE rānei).
• Ngā paipa he paninga mata māmā (hei tauira, peita, aukati waikura) he waikura iti rānei, mena he angiangi, he ōrite hoki te paninga.
• Ko ngā paipa he rakuraku iti, he pona, he hononga whakarewa rānei, ki te kore ēnei e ārai nui, e marara rānei i ngā tohu ultrasonic.

Āhea te wā e tika ai te whakakanapa?

1. Te Waikura Mata Taumaha, te Unahi, te Waikura rānei

• Ka taea e ngā paparanga matotoru o te waikura, te unahi, te waikura rānei i runga i ngā paipa whakarewa te mimiti, te marara rānei i ngā ngaru ultrasonic, ka ngoikore ai te tohu i waenga i te tuku me te kaiwhiwhi. Ka whakaitihia te tika o te ine, ka ngaro rānei te tohu.
• Otinga: Whakakanapa mārietia (hei tauira, ki te pepa kirikiri, ki te paraihe waea rānei) hei tango i te waikura/te unahi e memeha haere ana, kia maeneene ake ai te mata, kia ma ake ai te hononga oro.

2. Ngā Paninga, te Peita rānei, Matotoru, Kāore i te ōrite

• Ka taea e ngā paipa he peita matotoru (hei tauira, he maha ngā paparanga), he uku, he paninga rānei te mahi hei ārai oro. Mā ngā paninga kāore i te ōrite ka puta he tuku tohu kāore i te ōrite.
• Otinga: Mena he matotoru te paninga (>1–2 mm) he koretake rānei, mā te oro mārire, mā te waru mārire rānei i te wāhi e whakairihia ai ngā ira whakawhiti hei whakaatu i tētahi paninga maeneene, angiangi (he konganuku tahanga rānei) ka pai ake te hononga.

3. Ngā Karawarawa Hōhonu, ngā Poka, ngā Putanga Whakarewa rānei

• Ka taea e ngā hapa nui o te mata (hei tauira, ngā rakuraku hōhonu, ngā pirepire whakarewa, ngā pakaru rānei) i te wāhi whakamau i te transducer te whakararuraru i te ara ultrasonic, ka arahi ki te whakapōturitanga o te tohu.
• Otinga: Whakakanapahia kia maeneene ai ngā taha koi, ngā pūwero rānei, kia tino pā ai ngā mata o te ine ki te mata o te paipa.

4. Hononga Oro Kino

• Otinga: Mā te oro ka hangaia he mata papatahi, maeneene, ka taea ai e te tiēre te hanga i tētahi paparanga tonu, kāore he mirumiru mō te whakawhiti oro tino pai.

Ngā Whakaaro Matua mō te Whakakanapa

• Te whānuitanga o te whakakanapa: Ko te wāhi iti anake kei reira ngā whakawhiti hiko (e 2–3 ngā wā te whānui o te whakawhiti hiko) me aro atu. Ko te toenga o te paipa kāore e pāngia.
• Rauemi paipa: Mō ngā konganuku ngohengohe (parahi, konumohe) me ngā kirihou rānei, he rawaka te oro mārie (me te pepa oro pai). Mō ngā konganuku mārō (maitai), me whakamahi pea he paraihe waea, he papa oro rānei.
• Kaua e whakakanapa rawa: Ki te whakakanapa rawa, ka angiangi te pakitara o te paipa (ka kino pea) ka hanga rānei he mata piko, ka mau tonu pea te hau. Me whai kia maeneene, kia papatahi te mata.

Ina Kāore e Hiahiatia te Whakakanapa

• Ngā paipa maeneene, ma: Kāore e hiahiatia ana te whakakanapa i ngā paipa hou me ngā mata kua oti te hanga mai i te wheketere (hei tauira, te PVC maeneene, te maitai kore waikura, te maitai kua peitatia rānei me ngā paninga angiangi, ōrite).
• He paru māmā te mata: He nui noa te horoi noa ki te kakahu me te waipiro hei tango i te paru, te hinu, te para rānei—kāore e hiahiatia he oro.
