Izinto Eziphambili Ezibangela Ingxolo Nokungcangcazela

1. Ulwelo olutshintshatshintshayo: Umthombo wengxolo olawulayo (＞60% yengxolo iyonke) 14

• Ukuxinana koxinzelelo: Ukuvulwa/ukuvalwa kwevalvu ngokukhawuleza kudala ukunyuka koxinzelelo ngexesha lemijikelo yokufunxa/yokukhupha, nto leyo evelisa ingxolo ephantsi (20–500 Hz).

• Ukukhupha umoya: Kwiqondo lobushushu eliphezulu okanye i-vacuum ephantsi, ulwelo luyajika lube ngamaqamza aqhuma ngamandla, nto leyo ebangela ukungcangcazela okukhulu (＞10 kHz) kunye nokukhukuliseka kwecandelo 14.

• I-Turbulence kunye neeVortices: Ukuhamba okungazinzanga kwimibhobho kuvuselela isandi solwakhiwo, kwandisa ingxolo nge-6–15 dB 4.

2. Amandla Oomatshini: Ii-Amplifiers Zokungcangcazela

• Ukudinwa yiDiaphragm Flex: Iimembrane zePTFE/EPDM zinyamezela imijikelo ye-flex engama-50–100/imizuzwana. Uyilo olungalinganiyo kakuhle ludala uxinzelelo olungenamlinganiselo, lusasaza ii-micro-cracks kwaye luvelise ingxolo ye-frequency ephakathi (500–2k Hz) 15.

• Iinkqubo zokuqhuba ezingaqhelekanga: Unxibelelwano okanye iibheringi ezingalungelelananga kakuhle zibangela amandla angalinganiyo, zikhawulezisa ukuguguleka kweeshafti kunye neevalvu 18.

• Impembelelo yeValve: Jonga ukuba iivalve zivalekile ngesantya esiphezulu se-＞5 m/s zivelisa izandi ezibukhali "zokukhaba" (＞3k Hz) kunye namaza okutshayisa 2.

3. Ingxolo Ebangelwa Yimoto: Isixhobo Sokubangela Umbane 14

• I-Electromagnetic Ripple: Amandla emagnethi angalinganiyo kwiimoto zeDC ezixutyiweyo ashukumisa ii-stators (120–240 Hz hum).

• Ukungqubana kweeBearing/Brush: Iindawo eziqengqelekayo ezingagqibelelanga okanye i-commutator arcing yongeza ingxolo ye-broadband.

• Iifeni Zokupholisa: Ukuphazamiseka okuvela kwii-impellers kuncedisa ekukrwitsheni okuphezulu (＞8k Hz).

4. Isandi seNqanaba leNkqubo: I-Silent Aggravator

• Ukungcangcazela kwePipework: Iipayipi eziqinileyo zikhulisa ukushukuma kwepompo, zisebenza njenge-antenna yengxolo 13.

• Iindawo Zokufaka: Iiphaneli ezincinci (<3 mm) zivakala kwi-100–400 Hz, zinyusa isandi esibonwayo nge-12 dB 37.

Amaqhinga Okunciphisa Ingxaki Aqinisekisiweyo

A. Ukuphuculwa kweFluid Dynamics

• Uyilo oluchasene nokuCavitation:

  • Yongeza uxinzelelo lokungena okanye unciphise ubushushu ukuze uthintele ukwakheka kwamaqamza.

  • Sebenzisa izihlalo zeevalvu ezinciphileyo ukuze utshintshele ukuhamba kwamanzi kakuhle, unciphise ukwehla koxinzelelo ngama-40% 4.

• Izinto zokudambisa ukubetha kwentliziyo:

  • Faka iitanki ze-buffer (＞10% yokufuduka kwepompo) okanye iziteshi zokuhamba nge-helical ukuze zifunxe ii-spikes zoxinzelelo, zinciphise ingxolo nge-50% 46.

B. Ukuphuculwa koomatshini kunye nezinto

• IiDiaphragm eziBalaseleyo:

  • Iimembrane ze-PTFE ezigobileyo (umz., i-KNF NMP 830) zinciphisa uxinzelelo lokugoba nge-30% xa kuthelekiswa noyilo oluthe tyaba 5.

  • Iingubo zeNanocomposite (umz., iGraphene-PTFE) ziyamelana nokudinwa kangangemijikelo engaphezu kwama-500,000.

• IiValve Ezinefuthe Eliphantsi:

  • Iivalvu zePiezoelectric zisebenza nge-2 ms (xa kuthelekiswa ne-20 ms kwizipringi), zisusa ingxolo "yehamile yamanzi" 7.

C. Uyilo lweeMoto kunye noQhubo

• IiMoto ze-DC ezingenabhrashi (BLDC):

  • Susa ingxolo ye-commutator kwaye unciphise ii-harmonics ze-electromagnetic nge-90% 4.

• Iisekethe zeSoft-Start:

  • I-voltage ye-ramp engaphezulu kwe-50–200 ms, ithintela ukunyuka kwamandla ombane okubangela i-resonance 6.

D. Ukulungiswa koHlanganiso lweNkqubo

• Ukuzahlula ekungcangcazeleni:

  • Sebenzisa izixhobo zokugquma irabha ye-silicone (<40 Shore A) okanye izithinteli zentwasahlobo ukunciphisa ingxolo ethwalwa yisakhiwo nge-8–15 dB 35.

• Unyango lwe-Acoustic:

  • Songa iimpompo kwi-micro-perforated foam (＞30 PPI) okanye ufake ii-expansion chambers ukuze unciphise ingxolo ye-125–500 Hz 47.
