Zvinhu Zvikuru Zvinokonzera Ruzha & Kudedera

1. Kuchinjana Kwemvura: Kunobva Ruzha Rwakanyanya (＞60% yeruzha rwese) 14

• Kuvhurika/kuvhara kwevharuvhu nekukurumidza kunoita kuti kuvhurika kwemhepo kuwedzere panguva yekudhonza/kuburitsa mweya, zvichikonzera ruzha rusingawanzoitiki (20–500 Hz).

• Kuvharwa kwemvura: Pakupisa kwakanyanya kana kuti vacuum yakaderera, mvura inoputika kuita mabubbles anoputika zvine simba, zvichikonzera kudedera kukuru (＞10 kHz) uye kukanganiswa kwezvikamu 14.

• Kutenderera Kwemhepo Nemapombi: Kuyerera kusina kugadzikana mumapombi kunokurudzira ruzha rwechimiro, zvichiwedzera ruzha ne6–15 dB 4.

2. Masimba eMechanical: MaAmplifiers eKudedera

• Kuneta kweDiaphragm Flex: Ma membrane ePTFE/EPDM anogara kwenguva ye50-100 flex cycles/sec. Magadzirirwo asina kuenzana zvakanaka anogadzira kushushikana kusingaenzaniswi, zvichiparadzira ma micro-cracks uye zvichigadzira ruzha rwepakati (500-2k Hz) 15.

• Masisitimu Ekufambisa Akabatana: Kubatana kusina kurongeka kana mabheringi anokonzera masimba asina kuenzana, zvichikurumidzisa kupera kwemashaft nemavharuvhu 18.

• Kukanganiswa kweVharuvhu: Tarisa mavharuvhu achivhara ne ＞5 m/s anogadzira ruzha rwakapinza rwekuti "ticking" (＞3k Hz) uye mafungu ekuvhunduka 2.

3. Ruzha Runokonzerwa Nemota: Chinokonzeresa Magetsi 14

• Electromagnetic Ripple: Masimba emagineti asina kuenzana ari mumamota eDC akabhurwa anodedera ma stator (120–240 Hz hum).

• Kukweshana kweBheari/Bhurashi: Nzvimbo dzisina kukwana dzekutenderera kana kutenderedza mafambiro emagetsi kunowedzera ruzha rwebroadband.

• Mafeni Anotonhodza: ​​Kusagadzikana kunobva kumaimpellers kunoita kuti pave nekuchema kwakanyanya (＞8k Hz).

4. Kunzwa Kwemazinga Ehurongwa: Chinhu Chinomutsa Chinyararire

• Kudedera kweMapaipi: Mapaipi akaomarara anokudza kupururudza kwepombi, achiita seantenna yeruzha 13.

• Nzvimbo Dzekugadzika: Mapaneru matete (<3 mm) anorira pa100–400 Hz, zvichiwedzera ruzha rwunoonekwa ne12 dB 37.

Maitiro Akaratidza Ekuderedza Dambudziko

A. Kugadzirisa Kushanduka Kwesimba reMvura

• Magadzirirwo Anopesana Nekuvhuvhuta:

  • Wedzera kumanikidzwa kwekupinda kana kuderedza tembiricha kuti udzivise kuumbwa kwemabubble.

  • Shandisa zvigaro zvevharuvhu zvakatetepa kuti kuyerera kwemvura kuende zvakanaka, uchideredza kuderera kwedzvinyiriro ne40% 4.

• Zvinoderedza Kupisa Kwemhepo:

  • Isa matangi e-buffer (<10% yekuchinja kwepombi) kana nzira dzekuyerera dzakatenderera kuti dzitore simba rekumanikidza, zvichideredza ruzha ne50% 46.

B. Kuvandudzwa kweMichina neZvinhu

• Madhayafragimu Akaenzana:

  • Matanda ePTFE akakombama (semuenzaniso, KNF NMP 830) anoderedza kushushikana kwekukotama ne30% zvichienzaniswa nemagadzirirwo akatsetseka 5.

  • Mapurasitiki eNanocomposite (semuenzaniso, graphene-PTFE) anodzivirira kuneta kwe500,000+ cycles 4.

• Mavharuvhu Asina Simba:

  • Mavharuvhu epiezoelectric anomhanya mu 2 ms (vs. 20 ms yemasipiringi), achibvisa ruzha rwe "hammer yemvura" 7.

C. Kuvandudzwa kweMota neDrive

• Mota dzeDC dzisina brushless (BLDC):

  • Bvisa ruzha rwemagetsi uye deredza ma "electromagnetic harmonics" ne90% 4.

• Maseketi Anotanga Zvinyoro-nyoro:

  • Voltage yerampu inodarika 50–200 ms, ichidzivirira kukwira kwesimba remagetsi kunokonzera resonance 6.

D. Kugadziriswa kweKubatanidzwa kweSisitimu

• Kuzviparadzanisa Nekudedera:

  • Shandisa zvinhu zvinosungirirwa nesilicone-rabha (<40 Shore A) kana zvinodzivirira masimbi emuchina wekupisa kuti uderedze ruzha rwunofambiswa nechimiro ne8–15 dB 35.

• Kurapa Kwekurira Kwenzwi:

  • Putira mapombi mufuro rine maburi madiki (>30 PPI) kana kuisa makamuri ekuwedzera kuti aderedze ruzha rwe125–500 Hz 47.

Chidzidzo Chenyaya: Kunyaradza Pombi Yekunwa Mishonga

• Dambudziko: Ruzha rwe55 dB runobva mumuromo wemuromo uye kutaura kwevharuvhu zvakakanganisa kurara kwemurwere.

• Mhinduro:

  • Yakachinjwa kuita mota yeBLDC + diaphragm yakakombama

  • Tangi re 20 ml re buffer rakawedzerwa

  • Yakaiswa nesilicone isolators

• Mhedzisiro: Ruzha rwakaderera kusvika pa39 dB (pasi pezvinodiwa neICU husiku) 4.

Maitiro Akanakisisa Emainjiniya

1. Dzivisa Kumhanya Pasina Kuoma: > maminitsi mashanu pasina mvura inoyerera katatu kushushikana kwe diaphragm 1.

2. Shandisa Tubing Inochinjika: 30 cm silicone hoses kucheka pombi ne70% zvichienzaniswa nePVC yakasimba 3.

3. Tembiricha yekutarisa: >80°C inokurumidza kukwegura kwePTFE—deredza kumhanya kwepombi kana zvichidikanwa.

4. Taura Mapombi Ekutanga Ekusimbisa: Mamodheru akaita sePinmotor's WhisperSeries anobatanidza mamota eBLDC, mavharuvhu akapfava, uye masensa eIoT vibration ekutevera hutano panguva chaiyo.

Mafambiro Emangwana: Mapombi Akangwara Uye Akanyarara

• Kudzima Ruzha: Maikorofoni + masipika e-counter-phase anodzima matoni e100–800 Hz (kuderedzwa kwe12 dB kwakaratidzwa murabhoritari).

• Matumbu ekuzviongorora: Ma sensor ekumanikidzwa ari muma diaphragm anofungidzira kukundikana kwe80% muhupenyu hwekuneta 5.
