Design and Optimization of Compact Diaphragm Structures for Miniature Vacuum Pumps

Pompe ntoyanibintu byingenzi mubisabwa kuva mubikoresho byubuvuzi kugeza kwikora inganda, aho guhuzagurika, gukora neza, no kwizerwa aribyo byingenzi. Diaphragm, nkibice byingenzi bigize ayo pompe, bigira ingaruka kumikorere binyuze mubishushanyo mbonera byayo hamwe nibintu bifatika. Iyi ngingo irasobanura ingamba zihamye zo gushushanya no gutezimbere imiterere ya diaphragm yoroheje, ihuza udushya twibintu, kuzamura topologiya, hamwe nimbogamizi zinganda kugirango tugere kubisubizo bihanitse.

1. Udushya twibikoresho byo Kongera Kuramba no Gukora neza

Guhitamo ibikoresho bya diaphragm bigira ingaruka zikomeye kuramba no gukora neza:

Polimeri yo hejuru.
Ibikoresho: Ibishushanyo mbonera, nka karuboni-fibre-yongerewe imbaraga za polymers, bigabanya ibiro kugera kuri 40% mugihe ukomeje ubusugire bwimiterere.
Amavuta avanze.

Inyigo: Pompe yo mu rwego rwo kwa muganga ikoresheje diaphragms yometse kuri PTFE yageze ku kugabanuka kwa 30% no kugabanuka kwa 15% ugereranije n’ibishushanyo gakondo.

Uburyo bwiza bwo kubara butuma ibikoresho bisaranganya neza kugirango bingane imikorere nuburemere:

Ubwihindurize Bwubaka (ESO): Kuraho ibintu bidahangayikishije cyane, bigabanya diafragm ya 20-30% utabangamiye imbaraga.
Floating Projection Topology Optimisation (FPTO): Byatangijwe na Yan et al., Ubu buryo bushyira mu bikorwa ingano ntoya (urugero, 0,5 mm) kandi igenzura chamfer / impande zose kugirango zongere umusaruro.
Gukwirakwiza ibintu byinshi: Ihuza imihangayiko, kwimurwa, hamwe nimbogamizi zo guhuza diaphragm geometrie kugirango igabanye umuvuduko wihariye (urugero, -80 kPa kugeza -100 kPa).

Urugero: Diaphragm ya mm-25 ya diametre yatunganijwe neza binyuze muri ESO yagabanije guhangayikishwa na 45% mugihe ikomeza icyuho cya 92%.

3. Gukemura inzitizi zo gukora

Igishushanyo-cyo-gukora (DFM) amahame yemeza ko bishoboka kandi bigakorwa neza:

Kugenzura Ubunini Buke: Iremeza uburinganire bwimiterere mugihe cyo kubumba cyangwa gukora inyongeramusaruro. Algorithms ya FPTO igera ku gukwirakwiza umubyimba umwe, wirinda gutsindwa cyane.
Kuringaniza imipaka: Uburyo butandukanye bwo gushungura radiyo ikuraho inguni zikarishye, kugabanya imihangayiko no kuzamura ubuzima bwumunaniro.
Ibishushanyo mbonera: Ibice bya diafragm byateranijwe mbere byoroshya kwinjiza mumazu ya pompe, kugabanya igihe cyo guterana 50%.

4. Kwemeza Imikorere Binyuze mu Kwigana no Kwipimisha

Kwemeza ibishushanyo mbonera bisaba isesengura rikomeye:

Isesengura ryibanze rya nyuma (FEA): Ihanura ikwirakwizwa ryimyitwarire no guhindura ibintu munsi yikizamini. Parametric FEA moderi ituma itera yihuta ya diaphragm geometrie.
Kwipimisha umunaniro: Kwihutisha ibizamini byubuzima (urugero, 10,000+ cycle kuri 20 Hz) byemeza ko biramba, hamwe na Weibull isesengura ryerekana uburyo bwo gutsindwa nigihe cyo kubaho.
Kwipimisha no Kotsa igitutu: Gupima urwego rwa vacuum hamwe no gutembera neza ukoresheje protocole isanzwe ya ISO.

Ibisubizo.

5. Porogaramu hirya no hino mu nganda

Ibikoresho byiza bya diafragm byubaka bitera intambwe mubice bitandukanye:

Ibikoresho byo kwa muganga: Amapompo yambaye vacuum yokuvura ibikomere, kugera -75 kPa guswera hamwe n urusaku <40 dB.
Gukora inganda.
Gukurikirana Ibidukikije: Amapompo ntoya yo gutoranya ikirere, ahujwe na gaze zikaze nka SO₂ na NOₓ1.

6. Icyerekezo kizaza

Ibigenda bigaragara byizeza iterambere:

Diaphragms nziza: Byashyizwemo ibyuma byifashishwa mu kugenzura ubuzima-nyabwo no kubungabunga ubuzima.
Gukora inyongeramusaruro: 3D-icapuwe diaphragms hamwe na gradient porosity kugirango yongere imbaraga za fluid.
Gukoresha AI: Imashini yiga algorithms kugirango ishakishe geometrike idasobanutse kurenza uburyo bwa topologiya gakondo.

Umwanzuro

Igishushanyo nogutezimbere imiterere ya diaphragm yububiko bwaminiature vacuumbisaba uburyo butandukanye, guhuza siyanse yibintu, kwerekana imiterere, no gushishoza. Mugukoresha topologiya optimizasiyo hamwe na polymers yateye imbere, injeniyeri zirashobora kugera kuburemere bworoshye, burambye, kandi bukora ibisubizo bihuye nibisabwa bigezweho.
