Mapombi evacuum emicro diaphragm akakosha pakushandisa michina yekurapa, michina yekurabhoritari, uye otomatiki yemaindasitiri. Asi kana akashandiswa munzvimbo dzakakwirira (semuenzaniso, nzvimbo dzakakwirira kana makomo), uko kumanikidzwa kwemhepo kunoderera zvakanyanya, mainjiniya anotarisana nemibvunzo yakakosha nezvekushanda kwavo.

Fizikisi: Kureba Kunokanganisa Sei Kushanda Kwepombi Yevacuum

Padanho regungwa, kumanikidzwa kwemhepo kwakajairika kuri ~101.3 kPa. Pakukwirira kwe3,000m, kunodzikira kusvika ~70 kPa—kuchidzikira ne ~30%8. Izvi zvinokanganisa mapombi nenzira mbiri:

1. Kudzikiswa Kwepamusoro-soro Kwekuvharira Mvura:
   Pombi ine simba re -80 kPa pagungwa inogadzira -50 kPa chete pa3,000m nekuti vacuum inoyerwa.kana tichienzanisa nekumanikidzwa kwemhepo. Semuyenzaniso:

   *Pombi inosvika -70 kPa (yakaenzana) muChengdu (96 kPa) inongopa -66 kPa chete muGuangzhou (100 kPa)*8.

2. Kuderera Kwekuyerera Kwemvura:
   Kuwanda kwemhepo kunoderedza mamorekuru egasi pahuwandu hwegasi, zvichideredza kubuda kwemhepo. Pombi ine 25 L/min inoyerera pagungwa inogona kudzikira kusvika ≤18 L/min pa4,000m8.

Ruzivo Rwekuita Kwenyika Chairwo

Zvakakosha Kuziva: Apo mapombi achiriposhanda, kudzika kwevacuum uye kumhanya kunodzikira zvichienderana nekukwirira.

Njodzi Dzekushanda Munzvimbo Dzisina Kumanikidzwa Kwakanyanya

1. Kubvisa ganda:
   Kudzikira kwekumanikidzwa nekukurumidza mumakamuri epombi kunoita kuti mvura inenge yabatwa iite mhute, zvichiita kuti pave nemabubbles anoputika—achibvisa ma diaphragm nemavharuvhu. Izvi zvinowedzera kuipa kana paine kumanikidzwa kwakaderera.

2. Kupisa zvakanyanya:
   Mhepo yakatetepa inoderedza kushanda zvakanaka kwekutonhodza, ichikwidza tembiricha yemota ne15–20% uye ichikurumidzisa kupera simba.

3. Kubuda kweSimbiso:
   Kusiyanisa kwekumanikidzwa kunosimbisa zvisimbiso, zvichiwedzera njodzi dzekukundikana mukushandiswa kwakakosha sekusveta kwechiremba4.

Mhinduro dzeUinjiniya dzeKuvimbika Kwenzvimbo Dzakakwirira

1. Magadzirirwo Ane Mari Yekukwira

• Kudzora MaSensor Ekumanikidza + PID:
  Mapombi akaita seKNF N816 anoshandisa mhinduro chaiyo panguva chaiyo kugadzirisa kumhanya kwemota, achichengetedza vacuum yakasimba pasinei nekuchinja kwekumanikidzwa4.

• Kupomba Kwematanho Akawanda:
  Mamodheru ane matanho maviri (semuenzaniso, HG-30D) anodzikisa kumanikidzwa kwakapatsanurwa, achichengetedza vacuum yakadzika (-95 kPa) kunyangwe pa4,000m7.

2. Kuvandudzwa Kwezvikamu Zvakakosha

• Madhayafragimu Akasimbiswa:
  Ma membrane ePTFE kana eEPDM anodzivirira kukuvara kwe cavitation uye kuneta kwe flex36.

• Kutarisira Kupisa:
  Mamota eDC asina mabhurashi (semuenzaniso, VAP2300) anoderedza kupisa, nepo madhishi ekupisa achibvisa kupisa kwakawandisa.

3. Dziviriro dzeSistimu

• Matangi eBuffer:
  Dzvinyisa kumanikidzwa kwemhepo, zvichideredza kusagadzikana kwekuyerera kwemhepo ne >40%2.

• Mafirita Ekupinda:
  Guruva rinovhara rinowanikwa munzvimbo dzakaoma munzvimbo dzakakwirira, zvichidzivirira kuvharika kwemavharuvhu3.

Mashandisirwo Akaratidza Munzvimbo Dzisina Kumanikidzwa

• Makiriniki ekurapa eTibet:
  Midziyo inotakurika yekusveta inoshandisa pombi dze diaphragm dzine matanho maviri inochengetedza -60 kPa yekurapa maronda pa4,500m7.

• Masensa Ezvakatipoteredza eAndes:
  Zviyereso zvegasi zvine mapombi anobhadharwa pakureba (semuenzaniso, KVP300) zvinowana kuyerera kwakafanana kweCO₂ yekutarisa1.

• Kuedzwa kweNdege:
  Makamuri evacuum anotevedzera 10,000m anoshandisa mapombi ane nhanho dzakawanda ane <5% performance drift8.

Zvinodiwa Pakusarudza Zvinhu Zvinokosha Pakushandisa Nzvimbo Yakakwirira

1. Kushivirira Kugadzikana kweVacuum:
   Taura mapombi akaongororwa kuti <±2% afambe pakati pema "pressure ranges" (semuenzaniso, KNF LabVAC series)4.

2. Zvitupa:
   Kuvhara kweIP54 (kuramba guruva/hunyoro) uye -20°C kusvika 50°C nzvimbo yekushanda68.

3. Kujeka kweData:
   Kumbira mishumo yekuedza kwemugadziri inoratidza mashandiro ari pakakwirira kwakafanana (semuenzaniso, 0–5,000m).

Mhedziso: Ehe, neSmart Engineering

Pombi dzevacuum dze micro diaphragm dzinoshanda munzvimbo dzakakwirira—asi dzinoda magadzirirwo akagadziridzwa kuti dzidzivirire kudzika kwevacuum, kuora kwemvura, uye cavitation. Pamashandisirwo akakosha:

• Isa pombi dzine matanho akawanda kana kuti dzakavharika.

• Simbisa mashandiro ari padanho rako rekukwirira.

• Batana nevagadziri vane ruzivo mukushandisa michina isina kumanikidzwa zvakanyanya.

"Muinjiniya yepamusoro-soro, kufungidzira zvinoshanduka pakumanikidzwa kunoparadzanisa zvishandiso zvinoshanda kubva kumasisitimu asingakanganise kutadza."
