Fisiks: Kamoo Bophahamo bo Amang Tshebetso ya Pompo ya Vacuum

Boemong ba leoatle, khatello e tloaelehileng ea sepakapaka ke ~101.3 kPa. Ha e le bophahamong ba limithara tse 3,000, e theohela ho ~70 kPa—e fokotseha ka ~30%8. Sena se ama lipompo ka litsela tse peli:

1. Phokotso e Phahameng ea Vacuum:
   Pompo e lekantsoeng bakeng sa -80 kPa boemong ba leoatle e hlahisa -50 kPa feela ho 3,000m hobane vacuum e lekanngoaha ho bapisoa le khatello ea tikoloho. Ka mohlala:

   *Pompo e fihlellang -70 kPa (haholo-holo) Chengdu (96 kPa) e tla fana ka -66 kPa feela Guangzhou (100 kPa)*8.

2. Ho Fokotseha ha Sekhahla sa Phallo:
   Boima bo tlase ba moea bo fokotsa limolek'hule tsa khase ka bophahamo, e leng se fokotsang ho falla. Pompo e nang le phallo ea 25 L/min boemong ba leoatle e ka theohela ho ≤18 L/min ho 4,000m8.

2. Ho futhumatsa ho feta tekano:
   Moea o mosesaane o fokotsa bokgoni ba ho phodisa, o phahamisa mocheso wa enjene ka 15–20% mme o potlakisa ho tsofala6.

3. Ho Dutla ha Tiiso:

Litharollo tsa Boenjiniere bakeng sa Tšepo ea Libaka tse Phahameng

1. Meralo e Lefelloang ke Bophahamo

• Li-sensor tsa Khatello + Taolo ea PID:
  Lipompo tse kang KNF N816 li sebelisa maikutlo a nako ea sebele ho fetola lebelo la enjene, li boloka vacuum e tsitsitseng ho sa tsotelehe liphetoho tsa khatello4.

• Ho Pompa ka Mehato e Mengata:
  Mehlala ea mekhahlelo e 'meli (mohlala, HG-30D) phokotso ea khatello e arohaneng, e boloka vacuum e tebileng (-95 kPa) esita le ho 4,000m7.

2. Ntlafatso ea Likarolo tsa Bohlokoa

• Li-Diaphragm tse Matlafalitsoeng:
  Lera la PTFE kapa la EPDM le hanela tshenyo ya cavitation le mokhathala o tenyetsehang36.

• Tsamaiso ea Thermal:
  Li-motor tsa DC tse se nang borashe (mohlala, VAP2300) li fokotsa tlhahiso ea mocheso, ha li-heat sinks li felisa mofuthu o feteletseng6.

3. Litšireletso tsa Boemo ba Sistimi

• Litanka tsa Buffer:
  Fokotsa ho putlama ha khatello, ho fokotsa ho se tsitse ha phallo ka >40%2.

• Li-filter tsa ho kena:
  Thibela lerōle le tloaelehileng libakeng tse omeletseng tse phahameng, ho thibela ho koaloa ha li-valve3.

• Likliniki tsa Bongaka tsa Tibet:
  Lisebelisoa tse nkehang habobebe tsa ho monya tse sebelisang lipompo tsa diaphragm tsa mekhahlelo e 'meli li boloka -60 kPa bakeng sa kalafo ea maqeba ho 4,500m7.

• Li-sensor tsa Tikoloho tsa Andes:
  Disampole tsa khase tse nang le dipompo tse lefellwang bophahamo (mohlala, KVP300) di fihlella phallo e tsitsitseng bakeng sa ho lekola CO₂1.

• Teko ea Lifofane:
  Likamore tsa vacuum tse etsisang 10,000m li itšetlehile ka lipompo tsa mekhahlelo e mengata tse nang le ts'ebetso e tlase ho 5%.

Mekhoa ea Khetho ea Bohlokoa bakeng sa Tšebeliso ea Libaka tse Phahameng

1. Mamello ea Botsitso ba Vacuum:
   Hlalosa lipompo tse lekantsoeng bakeng sa ho kheloha ho <±2% ho pholletsa le maemo a khatello (mohlala, letoto la KNF LabVAC)4.

2. Lisetifikeiti:

Qetello: E, ka Boenjiniere bo Bohlale

Lipompo tsa vacuum tsa micro diaphragm li sebetsa libakeng tse phahameng—empa li hloka meralo e ntlafalitsoeng ea bophahamo ho thibela botebo bo fokotsehileng ba vacuum, ho bola ha phallo le ho ruruha ha cavitation. Bakeng sa lits'ebetso tsa bohlokoa:

• Beha pele lipompo tsa mekhahlelo e mengata kapa tse koetsoeng.

• Netefatsa tshebetso bophahamong boo o bo rerileng.

• Sebelisana le bahlahisi ba nang le boiphihlelo maemong a tšebeliso e tlase.

"Boenjiniere ba libaka tse phahameng, ho lebella liphetoho tsa khatello ho arola lisebelisoa tse sebetsang ho litsamaiso tse sireletsehileng."
