Mapampu a vacuum a micro diaphragm ndi ofunikira kwambiri pazida zachipatala, zida za labu, komanso makina odzipangira okha m'mafakitale. Koma akagwiritsidwa ntchito m'malo okwera kwambiri (monga mapiri kapena mapiri), komwe kuthamanga kwa mpweya kumatsika kwambiri, mainjiniya amakumana ndi mafunso ovuta okhudza momwe amagwirira ntchito. Tiyeni tifotokoze momveka bwino sayansi ndi mayankho.

Fiziki: Momwe Kutalika Kumakhudzira Kugwira Ntchito kwa Pumpu Yotsukira

Pamwamba pa nyanja, kuthamanga kwa mpweya wabwinobwino ndi ~101.3 kPa. Pamtunda wa mamita 3,000, kumatsika kufika ~70 kPa—kuchepa ndi ~30%8. Izi zimakhudza mapampu m'njira ziwiri:

1. Kuchepetsa Kuchuluka kwa Vacuum:
   Pampu yoyesedwa ya -80 kPa pamadzi imapanga -50 kPa yokha pa 3,000m chifukwa vacuum imayesedwapoyerekeza ndi kupsinjika kwa mlengalenga. Mwachitsanzo:

   *Pampu yofika -70 kPa (yofanana) ku Chengdu (96 kPa) ingapereke -66 kPa yokha ku Guangzhou (100 kPa)*8.

2. Kuchepa kwa Chiwongola dzanja:
   Kuchuluka kwa mpweya pang'ono kumachepetsa mamolekyu a mpweya pa voliyumu iliyonse, zomwe zimachepetsa kutuluka kwa mpweya. Pampu yokhala ndi madzi okwana 25 L/min panyanja ikhoza kutsika kufika pa ≤18 L/min pa 4,000m8.

Zoopsa Zogwira Ntchito M'malo Opanda Kupanikizika Kwambiri

1. Kutsegula m'mimba:
   Kutsika kwa kuthamanga kwa mpweya m'zipinda zopopera madzi kumachititsa kuti madzi omwe ali m'zipindazo asungunuke, zomwe zimapangitsa kuti thovu lomwe limaphulika—liwononge ma diaphragm ndi ma valve. Izi zimaipiraipira pakagwa mpweya wochepa25.

2. Kutentha Kwambiri:
   Mpweya wochepa umachepetsa mphamvu yoziziritsira, kukweza kutentha kwa injini ndi 15–20% ndikufulumizitsa kuwonongeka6.

3. Kutuluka kwa Chisindikizo:
   Kusiyana kwa kupanikizika kumatsekereza kupsinjika, zomwe zimawonjezera chiopsezo cha kulephera pakugwiritsa ntchito kofunikira monga kuyamwa kwachipatala4.

Mayankho a Uinjiniya Odalirika Kwambiri

1. Mapangidwe Okhala ndi Malire Okwera

• Masensa Opanikizika + Kuwongolera PID:
  Mapampu monga KNF N816 amagwiritsa ntchito mayankho a nthawi yeniyeni kuti asinthe liwiro la injini, kusunga vacuum yokhazikika ngakhale kusinthasintha kwa kupanikizika4.

• Kupopera kwa Masitepe Ambiri:
  Ma model a magawo awiri (monga HG-30D) kuchepetsa kuthamanga kwa mpweya, kusunga vacuum yozama (-95 kPa) ngakhale pa 4,000m7.

2. Kukweza Zinthu Zofunika Kwambiri

• Ma Diaphragm Olimbikitsidwa:
  Ma nembanemba a PTFE kapena EPDM amalimbana ndi kuwonongeka kwa cavitation komanso kutopa kwa flex36.

• Kusamalira Kutentha:
  Ma mota a DC opanda maburashi (monga VAP2300) amachepetsa kutentha, pomwe ma heat sinks amachotsa kutentha kochulukirapo6.

3. Chitetezo cha Pamlingo wa Dongosolo

• Matanki Osungiramo Zinthu Zofunika:
  Chepetsani kuthamanga kwa mpweya, kuchepetsa kusakhazikika kwa madzi ndi >40%2.

• Zosefera Zolowera:
  Fumbi lotchinga lomwe limapezeka m'malo ouma okwera kwambiri, zomwe zimathandiza kuti ma valve asatsekeke3.

Ntchito Zotsimikizika M'malo Otsika Opanikizika

• Zipatala Zachipatala za ku Tibet:
  Zipangizo zonyamulira zonyamula pogwiritsa ntchito mapampu a diaphragm okhala ndi magawo awiri zimasunga -60 kPa kuti zigwiritsidwe ntchito pochiza mabala pa 4,500m7.

• Masensa a Zachilengedwe ku Andes:
  Zitsanzo za gasi zokhala ndi mapampu opangidwa ndi kutalika (monga KVP300) zimakwaniritsa kuyenda koyenera kwa CO₂ kuwunika1.

• Kuyesa kwa Ndege:
  Zipinda zoyeretsera mpweya zomwe zimayezera mamita 10,000 zimadalira mapampu okhala ndi magawo ambiri okhala ndi <5% ya magwiridwe antchito8.

Zofunikira Zosankha Makiyi Ogwiritsira Ntchito Malo Okwera

1. Kulekerera Kukhazikika kwa Vacuum:
   Tchulani mapampu omwe ali ndi chiwerengero cha <±2% cha kusuntha kwa mpweya m'malo opanikizika (monga KNF LabVAC series)4.

2. Ziphaso:
   Kutseka kwa IP54 (kukana fumbi/chinyezi) ndi -20°C mpaka 50°C pamalo ogwirira ntchito68.

3. Kuwonekera kwa Deta:
   Pemphani malipoti oyesera opanga omwe akuwonetsa magwiridwe antchito pamalo okwera moyerekeza (monga, 0–5,000m).

Kutsiliza: Inde, ndi Smart Engineering

Mapampu a vacuum a micro diaphragm amagwira ntchito m'malo okwera kwambiri—koma amafunika mapangidwe abwino kwambiri kuti athetse kuchepa kwa kuzama kwa vacuum, kuwola kwa madzi, ndi kutsekeka kwa cavitation. Pa ntchito zofunika kwambiri:

• Ikani patsogolo mapompo okhala ndi magawo ambiri kapena otsekedwa.

• Tsimikizirani momwe zinthu zilili pamalo omwe mukufuna.

• Gwirizanani ndi opanga omwe ali ndi luso logwiritsa ntchito zinthu zochepa.

"Mu uinjiniya wa malo okwera kwambiri, zinthu zoyesera kuthamanga zimalekanitsa zida zogwirira ntchito ndi machitidwe otetezeka."
