2. Lub Zog Kho Tshuab: Cov Amplifiers Kev co

• Kev Qaug Zog ntawm Diaphragm Flex: PTFE/EPDM daim nyias nyias ua tau 50–100 lub voj voog flex/sec. Cov qauv tsim tsis sib npaug zoo tsim cov kev ntxhov siab tsis sib xws, nthuav tawm cov kab nrib pleb me me thiab tsim suab nrov nruab nrab (500–2k Hz) 15.

• Cov Txheej Txheem Tsav Tsheb Eccentric: Cov kev sib txuas lossis cov kabmob tsis sib xws ua rau muaj zog tsis sib npaug, ua rau cov ncej thiab cov li qub hnav sai dua 18.

• Kev Cuam Tshuam ntawm Lub Valve: Cov tshev valve kaw ntawm ＞5 m/s tsim cov suab "ticking" ntse (＞3k Hz) thiab cov nthwv dej poob siab 2.

3. Lub Suab Nrov Uas Lub Cev Muaj Zog Ua Rau: Lub Tshuab Hluav Taws Xob Ua Rau 14

• Electromagnetic Ripple: Cov zog sib nqus tsis sib xws hauv cov brushed DC motors co stators (120–240 Hz hum).

• Kev Sib Txhuam/Txhuam: Cov nplaim dov tsis zoo lossis kev sib txhuam ntawm lub commutator ua rau muaj suab nrov dav.

• Cov kiv cua txias: Kev co ntawm cov impellers ua rau muaj suab nrov ntau zaus (> 8k Hz).

4. Kev Sib Txuas Lus Qib System: Tus Neeg Ua Rau Neeg Nyuaj Siab

• Kev co ntawm cov kav dej: Cov kav dej khov kho ua rau cov twj tso kua mis txav mus los ntau dua, ua haujlwm zoo li lub kav hlau txais xov suab nrov 13.

• Cov Nto Mounting: Cov vaj huam sib luag nyias nyias (<3 hli) resonate ntawm 100–400 Hz, ua rau lub suab nrov dua los ntawm 12 dB 37.

Cov Tswv Yim Tiv Thaiv Kev Txo Qhov Mob Uas Tau Pom Zoo

A. Kev Txhim Kho Cov Kua Dej Dynamics

• Cov Qauv Tiv Thaiv Cavitation:

  • Ua kom lub siab nkag los yog txo qhov kub kom tsis txhob muaj npuas.

  • Siv cov rooj zaum ntawm lub valve tapered kom du thiab hloov pauv dej ntws, txo qhov siab poob los ntawm 40% 4.

• Cov khoom siv pulsation:

  • Nruab cov buffer tanks (＞10% ntawm qhov chaw tso kua mis) lossis cov channel ntws helical kom nqus tau cov suab nrov, txo cov suab nrov los ntawm 50% 46.

B. Kev Txhim Kho Tshuab thiab Khoom Siv

• Cov Diaphragms Sib Npaug:

  • Cov PTFE daim nyias nyias (piv txwv li, KNF NMP 830) txo qhov kev ntxhov siab ntawm kev khoov los ntawm 30% piv rau cov qauv tiaj tus 5.

  • Cov txheej txheej Nanocomposite (piv txwv li, graphene-PTFE) tiv taus kev qaug zog rau 500,000+ lub voj voog 4.

• Cov Li Qub Uas Muaj Kev Cuam Tshuam Tsawg:

  • Cov piezoelectric valves ua haujlwm hauv 2 ms (piv rau 20 ms rau cov springs), tshem tawm lub suab nrov "water hammer" 7.

C. Kev Tsim Kho Tshiab ntawm Lub Cev Muaj Zog & Kev Tsav Tsheb

• Cov Tsav Tsheb DC Txhuam (BLDC):
