• Pherekano le Metsamao e Meholo: Phallo e sa tsitsang liphaepheng e tsosa molumo oa sebopeho, e eketsa lerata ka 6–15 dB 4.

2. Matla a Mekaniki: Li-Amplifiers tsa ho Thothometsa

• Mokhathala o Fokolang oa Diaphragm: Methapo ea PTFE/EPDM e mamella lipotoloho tse 50-100 tsa ho flex/mots. Meralo e sa leka-lekanang hantle e baka khatello e sa lekanang, e jalang mapetso a manyane le ho hlahisa lerata la maqhubu a mahareng (500-2k Hz) 15.

• Mekhoa ea ho Tsamaisa e sa Lekaneng: Likhokahano kapa li-bearings tse sa tsamaellaneng hantle li baka matla a sa leka-lekanang, li potlakisa ho tsofala ha li-shaft le li-valve 18.

• Tšusumetso ea Valve: Hlahloba hore li-valve lia koala ka lebelo la ＞5 m/s li hlahisa melumo e bohale ea "ho thothomela" (＞3k Hz) le maqhubu a ho tšoha 2.

3. Lerata le Bakoang ke Motlakase: Sesosa sa Motlakase 14

• Ho Ripple ha Elektromakenete: Matla a makenete a sa lekanang ka har'a li-motor tsa DC tse brushed a thothomela li-stator (120–240 Hz hum).

• Khohlano ea Bearing/Brashi: Libaka tse sa phethahalang tsa ho phutholoha kapa ho chencha ha commutator ho eketsa lerata la broadband.

• Li-Fan tse Pholisang: Pherekano e tsoang ho li-impeller e tlatsetsa ho lla ha maqhubu a phahameng (＞8k Hz).

4. Ho utloahala ha boemo ba sistimi: Sefutho se sa thabiseng

• Ho thothomela ha liphaephe: Ho thiba ho thata ho hodisa ho tjhesa ha pompo, ho sebetsa jwalo ka antenna ya lerata 13.

• Libaka tsa ho Hloma: Liphanele tse tšesaane (<3 mm) li utloahala ka molumo o matla ho 100–400 Hz, li eketsa molumo o utloahalang ka 12 dB 37.

Maano a Pakiloeng a ho Fokotsa Tlokotsi

A. Ntlafatso ea Matla a Mokelikeli

• Meralo e Khahlanong le ho Hlakola:

  • Eketsa khatello ea ho kena kapa fokotsa mocheso ho thibela ho thehoa ha lipululana.

  • Sebelisa litulo tsa li-valve tse tenyetsehang ho etsa phetoho e boreleli ea phallo, ho fokotsa ho theoha ha khatello ka 40% 4.

• Li-Dampener tsa Pulsation:

  • Kenya litanka tsa buffer (＞10% ea ho falla ha pompo) kapa likanale tsa phallo ea helical ho monya likhatello tse phahameng, ho fokotsa lerata ka 50% 46.

B. Ntlafatso ea Mekaniki le Lisebelisoa

• Li-diaphragm tse Leka-lekaneng:

  • Merapo ea PTFE e kobehileng (mohlala, KNF NMP 830) e fokotsa khatello ea ho kobeha ka 30% khahlano le meralo e bataletseng 5.

  • Liaparo tse nang le nanocomposite (mohlala, graphene-PTFE) li hanela mokhathala ka lipotoloho tse fetang 500,000.

• Li-valve tse nang le tšusumetso e tlase:

  • Li-valve tsa piezoelectric li sebetsa ka 2 ms (ha li bapisoa le 20 ms bakeng sa liliba), li felisa lerata la "hamore ea metsi" 7.

C. Mekhoa e Mecha ea Likoloi le Lipalangoang

• Li-motor tsa DC tse se nang borashe (BLDC):

  • Tlosa lerata la commutator 'me u fokotse li-harmonics tsa motlakase ka 90% 4.

• Lipotoloho tsa ho Qala ka Bonolo:

  • Motlakase o fetang 50–200 ms, o thibela ho phahama ha motlakase ho tsosang modumo o matla 6.

D. Litokiso tsa Kopanyo ea Sistimi

• Ho Ikarola ha ho Thothometsa:

  • Sebelisa lithapo tsa silicone-rabara (<40 Shore A) kapa li-damper tsa selemo ho fokotsa lerata le tsamaisoang ke sebopeho ka 8–15 dB 35.

• Kalafo ea Molumo:

  • Phuthela lipompo ka foam e nang le masoba a manyane (> 30 PPI) kapa kenya likamore tsa katoloso ho fokotsa lerata la 125–500 Hz 47.
