Ngā papu diaphragm itiHe mea nui ki ngā taputapu hauora, ki ngā taputapu taiwhanga, me ngā pūnaha ahumahi tino tika—engari he uaua tonu te haruru me te wiri. Ko te haruru nui rawa (>45 dB) me te wiri rānei ka tohu i te pakaru wawe, te whakahaere wai hē, te rahunga rānei o te pūnaha. Ka tātarihia e mātou te pūtaiao kei muri i ēnei take me ngā otinga hou hei whakatutuki i te mahi marino, pumau.

Ngā Take Matua e Ārahi Ana i te Haruru me te Wiri

1. Ngā Āhuatanga Wai: Te Pūtake Haruru Matua (>60% o te haruru katoa) 14

• Ngā Pāpātanga Pēhanga: Mā te whakatuwheratanga/katinga tere o te takirere ka puta he pikinga pēhanga i ngā huringa momi/tukunga, ka puta he haruru auau iti (20–500 Hz).

• Te Āputaputa: I ngā pāmahana teitei, i ngā pāmahana korehau iti rānei, ka mimiti te wai hei mirumiru ka pakū kaha, ka puta he wiri nui (>10 kHz) me te memeha o ngā wāhanga 14.

• Te Hurihuri me ngā Āwhiowhio: Ka whakaoho te rere pōturi i roto i ngā paipa i te haruru hanganga, ka whakanui ake i te haruru mā te 6–15 dB 4.

2. Ngā Kaha Ā-Mīhini: Ngā Whakakaha Wiri

• Ngenge o te Pūwero Diaphragm: Ka taea e ngā kiriuhi PTFE/EPDM te tu atu i ngā huringa pūwero 50–100/hēkona. Mēnā kāore i te taurite te āhua, ka puta he ahotea kore taurite, ka horapa ngā kapiti moroiti, ka puta hoki he haruru auau-waenga (500–2k Hz) 15.

• Ngā Pūnaha Puku Tauhou: Ka puta he kaha kore taurite i ngā hononga, i ngā peera rānei kāore i te tū tika, ka tere ake te pakaru o ngā toki me ngā takirere 18.

• Pānga o te Takirere: Ina kati ngā takirere ārai i te ≥5 m/s, ka puta he oro "tā" koi (≥3k Hz) me ngā ngaru ru 2.

3. Haruru i Āraia e te Mōta: Te Pūhiko Hiko 14

• Riri Hikohiko: Ngā kaha aukume kore taurite i roto i ngā motuka DC paraihe e wiri ana i ngā stator (120–240 Hz hum).

• Te Waku o te Peihana/Paraihe: Ka tāpirihia he haruru whānui e te koretake o ngā mata hurihuri, te āwhata rānei o te commutator.

• Ngā Pā Whakamatao: Ka puta te aue auau teitei mai i te aueue o ngā impeller (>8k Hz).

4. Te Āhuatanga Taumata-Pūnaha: Te Kaiwhakaoho Wahangu

• Te wiri o ngā paipa: Ka whakanui ake ngā ngongo mārō i ngā pao o te papu, ka mahi hei pūihi haruru 13.

• Ngā Papa Whakamau: Ka haruru ngā panera angiangi (<3 mm) i te 100–400 Hz, ka whakanui ake i te haruru e rangona ana mā te 12 dB 37.

Ngā Rautaki Whakaiti Kua Whakamātauhia

A. Te Arotautanga o te Arotautanga o te Wai

• Ngā Hoahoa Ārai-Cavitation:

  • Whakanuia te pehanga tomo, whakaitihia rānei te pāmahana hei pehi i te hanganga mirumiru.

  • Whakamahia ngā nohoanga takirere whakarara hei whakahaere i te whakawhiti rere, hei whakaiti i te hekenga pēhanga mā te 40% 4.

• Ngā Whakaiti Pupuhi:

  • Tāutahia ngā tāke ārai (>10% o te nekehanga papu) me ngā awa rere porowhita rānei hei mimiti i ngā pikinga pēhanga, hei whakaiti i te haruru mā te 50% 46.

B. Ngā Whakapai Ake i te Mīhini me te Rauemi

• Ngā Diaphragm Taurite:

  • Ka whakaitihia e ngā kiriuhi PTFE piko (hei tauira, KNF NMP 830) te ahotea piko mā te 30% ki ngā hoahoa papatahi.

  • Ka ātete ngā paninga nanocomposite (hei tauira, graphene-PTFE) ki te ngenge mō ngā huringa 500,000+

• Ngā Takirere Pānga-Iti:

  • Ka tere te mahi a ngā takirere piezoelectric i roto i te 2 ms (whakataurite ki te 20 ms mō ngā puna), ka whakakorea te haruru "hama wai" 7.

C. Ngā Auahatanga Mōta me te Taraiwa

• Ngā Mōta DC Kore Paraihe (BLDC):

  • Whakakorehia te haruru o te commutator me te whakaiti i ngā harmonics electromagnetic mā te 90% 4.

• Ngā Ara Hāora Tīmata-Ngāwari:

  • Te ngaohiko piki i runga ake i te 50–200 ms, e ārai ana i ngā ngaru iahiko e whakaoho ana i te haruru 6.

D. Ngā Whakatikatika Whakaurunga Pūnaha

• Wehewehenga Wiri:

  • Whakamahia ngā whakapiringa rapa-silicone (<40 Shore A) me ngā ārai puna rānei hei whakaiti i te haruru o te hanganga mā te 8–15 dB 35.

• Ngā Maimoatanga Oro:

  • Tākaihia ngā papu ki te pahuka moroiti-pū (>30 PPI) tāutahia rānei ngā rūma whakawhanui hei whakaiti i te haruru 125–500 Hz 47.

Ngā Tikanga Pai rawa atu mō ngā Kaihangarau

1. Kaua e oma maroke: >5 meneti me te kore he pēhanga wai-toru o te diaphragm 1.

2. Whakamahia ngā Ngongo Ngāwari: ka tapahia e ngā ngongo silicone 30 cm te haruru o ngā paipa mā te 70%, ki te whakaritea ki ngā ngongo PVC mārō 3.

3. Aroturuki i ngā Pāmahana: Ka tere ake te tawhito o te PTFE i te >80°C—whakaitihia te tere o te papu mēnā e tika ana.

4. Tauwhāitihia ngā Papu Pūmautanga-Tuatahi: Ko ngā tauira pēnei i a WhisperSeries a Pinmotor e whakauru ana i ngā motuka BLDC, ngā takirere whakamakuku, me ngā pūoko wiri IoT mō te aroturuki hauora wā-tūturu.
