Ngati mukuphatikizampope wochepa wotulutsa mpweyaMu chipangizo chachipatala, chipangizo cha labotale, kapena ntchito zamafakitale, funso limodzi lofunika kwambiri ndi lakuti: "Kodi vacuum imatha kukoka mphamvu yotani?" Makamaka, kwa munthu amenempope wothira mpweya, yankho lake limatanthauzidwa ndi kukakamiza kwake kwakukulu, mfundo yofunika kwambiri yomwe imatsimikiza kuyenerera kwake pa ntchito yanu.

Nkhaniyi ikufotokoza zinthu zomwe zimakhudza kuchuluka kwa vacuum m'mapampu awa ndi zomwe mungayembekezere.

Kodi Pumpu Yopopera ya Diaphragm ndi chiyani?

Ampope wothira mpweyandi mtundu wa pampu yosinthira yomwe imagwiritsa ntchito diaphragm yozungulira, ma valve owunikira, ndi chipinda chopangira vacuum. Kugwiritsa ntchito kwawo kopanda mafuta komanso kouma kumapangitsa kuti zikhale zabwino kwambiri pakugwiritsa ntchito komwe ukhondo ndi kunyamulika ndizofunikira kwambiri.

Ma Vacuum Range Odziwika Bwino a Mapampu Ang'onoang'ono a Diaphragm

Ngakhale kuti mphamvu zimasiyana malinga ndi mtundu ndi mtundu, mayunitsi ambiri ang'onoang'ono a vacuum pump a mtundu wa diaphragm amakhala ndi vacuum yabwino kwambiri (kupanikizika kochepa komwe angafikire) m'mitundu iyi:

Mainchesi 15 mpaka 29.9 a Mercury (inHg) kapena 50 mpaka 760 Torr kapena -7 mpaka -100 kPa (gauge).

• Mapeto Otsika (Cholinga Chachikulu): ~15-20 inHg (-50 mpaka -67 kPa). Amapezeka kwambiri m'mapampu otsika mtengo ogwiritsidwa ntchito monga kusanthula mpweya, kuyamwa mosavuta, kapena kugwira.

• Mapampu Apamwamba (Omwe Ali ndi Kalasi Yachipatala & Ya Laboratory): ~22-29.9 inHg (-75 mpaka -100 kPa). Awa ndi mapampu ogwira ntchito kwambiri omwe amagwiritsidwa ntchito pofufuza magazi, kusefa, ndi zida zodziwira matenda zokha.

Ponena za nkhani:

• Kupanikizika kwa mpweya: 0 inHg (gauge) kapena 101.3 kPa (absolute)

• Vacuum Yabwino Kwambiri: 29.92 inHg (gauge) kapena -101.3 kPa (gauge)

Izi zikutanthauza khalidwe lapamwambampope wothira mpweyaimatha kuchotsa pafupifupi 95-99% ya mpweya kuchokera pa voliyumu yotsekedwa.

Zinthu Zofunika Zomwe Zimachepetsa Kutsika kwa Pampu ya Diaphragm

Zinthu zingapo zomwe zimapangidwa zimalepheretsa pampu ya diaphragm kufika pa vacuum yabwino kwambiri:

1. Kugwira Ntchito Bwino kwa Volumetric ndi "Dead Volume": Palibe pampu yomwe ingachotse mpweya wonse m'chipinda chopondereza. Mpweya wochepa wotsala, wotchedwa "dead volume," umasungidwa pambuyo pa kugwedezeka kulikonse ndipo umakulitsidwanso, zomwe zimachepetsa kuthamanga kochepa komwe kungatheke.

2. Kutayikira kwa Chisindikizo ndi Vavu: Kutayikira kwa microscopic kudutsa chisindikizo cha diaphragm kapena mavavu oyesera kungathandize kuti mpweya ubwererenso kumbali ya vacuum. Mapampu apamwamba amagwiritsa ntchito zida zokonzedwa bwino komanso zipangizo zabwino kwambiri kuti achepetse izi.

3. Kutulutsa mpweya m'zinthu: Pansi pa vacuum, zinthu zina (monga mapulasitiki kapena ma rabara) zimatha kutulutsa mpweya kapena nthunzi zomwe zagwidwa mkati mwa kapangidwe kake. Chodabwitsa ichi, chotchedwa outgassing, chimathandizira kupanikizika mkati mwa dongosolo ndikupanga pansi lomwe pampu silingathe kugonjetsa.

4. Kusinthasintha ndi Kutseka kwa Diaphragm: Kusinthasintha kwa diaphragm yokha kumachepetsa chiŵerengero cha kupsinjika. Diaphragm yolimba kwambiri ingapangitse vacuum yolimba koma ingafunike mota yamphamvu kwambiri ndipo imakhala ndi kusinthana kwa nthawi yayitali.

Mapulogalamu ndi Vacuum Strength

• Vacuum Yochepa (15-20 inHg / -50 mpaka -67 kPa): Makapu ogwirizira, makina osavuta ogwiritsira ntchito mpweya, matumba otengera mpweya, zida zoyambira zokoka.

• Vacuum Yapakati (20-25 inHg / -67 mpaka -85 kPa): Kuyamwa mankhwala, kuyang'anira kuthamanga kwa magazi, mapampu a m'mawere, kugwiritsa ntchito madzi okha, makina opakira.

• Vacuum Yapamwamba/Yakuya (25-29.9 inHg / -85 mpaka -100 kPa): Kusefa kwa labotale, kuchotsa gasi mu vacuum, kugwiritsa ntchito semiconductor, zida zapamwamba zodziwira matenda.

Momwe Mungasankhire Pampu Yoyenera Kukwaniritsa Zosowa Zanu Zotulutsa Vacuum

1. Chongani Spec Sheet: Nthawi zonse yang'anani "Ultimate Vacuum" kapena "Final Vacuum", yoyezedwa mu inHg, kPa, kapena Torr. Iyi ndi mphamvu yotsika kwambiri ya pampu.

2. Ganizirani za Kuthamanga kwa Madzi: Pampu ikhoza kukhala ndi vacuum yozama, koma ngati ili ndi kuthamanga kochepa (CFM kapena LPM), zimatenga nthawi yayitali kuti ikafike kumeneko. Nthawi zambiri muyenera kulinganiza vacuum yomaliza ndi liwiro.

3. Mvetsetsani Zosowa za Dongosolo Lanu: Pampu iyenera kukhala yolimba mokwanira kuti ithetse kutayikira kulikonse mu dongosolo lanu ndikukwaniritsabe mphamvu yogwirira ntchito yofunikira pa ntchito yanu.

4. Ikani Ubwino Patsogolo: Pa ntchito zofunika kwambiri, gulani pampu yochokera kwa wopanga wodziwika bwino yemwe amagwiritsa ntchito ma valve ndi zomatira zapamwamba kuti atsimikizire kuti ikukwaniritsa magwiridwe antchito ake oyeretsedwa a vacuum.

Mapeto

Kotero, kodi ampope wochepa wa diaphragm vacuumKodi? Ngakhale kuti singathe kugwiritsa ntchito vacuum yochuluka kwambiri ngati mapampu akuluakulu ozungulira okhala ndi mafuta, pampu ya vacuum ya diaphragm yapamwamba kwambiri ndi yokhoza kwambiri, kufika pamlingo wa vacuum wotsika ngati 29 inHg (-98 kPa). Izi zimapangitsa kuti ikhale yankho lamphamvu, loyera, komanso lodalirika pa ntchito zosiyanasiyana zachipatala, mafakitale, ndi labotale. Mukasankha pampu, gwirizanitsani mosamala zomwe zikugwirizana ndi zofunikira za makina anu kuti muwonetsetse kuti ikugwira ntchito bwino.
