Design and Optimization of Compact Diaphragm Structures for Miniature Vacuum Pumps

Obere mgbapụta agụụbụ akụkụ dị oke mkpa na ngwa sitere na ngwaọrụ ahụike ruo na akpaaka ụlọ ọrụ, ebe kọmpat, arụmọrụ na ntụkwasị obi kacha mkpa. The diaphragm, dị ka isi akụkụ nke nfuli ndị a, na-emetụta kpọmkwem arụmọrụ site na nhazi ya na ihe onwunwe. Edemede a na-enyocha atụmatụ dị elu maka ịchepụta na ịkwalite nhazi kọmpat diaphragm, ijikọta ihe ọhụrụ ihe, njikarịcha topology, na mmachi nrụpụta iji nweta azịza dị elu.

1. Ihe ohuru ohuru maka imewanye ogologo oge na oru oma

Nhọrọ nke ihe diaphragm na-emetụta nke ukwuu ogologo ndụ mgbapụta na arụmọrụ arụmọrụ:

Polymers na-arụ ọrụ dị elu: PTFE (polytetrafluoroethylene) na PEEK (polyether ether ketone) diaphragms na-enye nguzogide kemịkalụ dị elu na esemokwu dị ala, dị mma maka ngwa na-emebi emebi ma ọ bụ dị elu.
Ngwakọta agwakọta: Nhazi ngwakọ, dị ka carbon-fiber-polymers, na-ebelata ibu site na 40% ma na-ejigide iguzosi ike n'ezi ihe.
Metal Alloys: Igwe anaghị agba nchara ma ọ bụ titanium diaphragms na-enye ike maka usoro nrụgide dị elu, na-eguzogide ike ọgwụgwụ karịa 1 nde cycles.

Ọmụmụ ihe: Igwe mgbapụta oghere ahụike nke na-eji diaphragms mkpuchi PTFE nwetara mbelata 30% na uwe na 15% dị elu karịa ka e jiri ya tụnyere atụmatụ rọba ọdịnala.

2. Topology Optimization for Lightweight and High-power Designs

Ụzọ mgbako dị elu na-eme ka nkesa ihe dị mma na-eme ka arụmọrụ na ịdị arọ kwekọọ:

Nkwalite Structural Evolushọn (ESO): Na-ewepụ ihe mgbakasị ala ugboro ugboro, na-ebelata oke diaphragm site na 20-30% na-emebighị ike.
Optimization Projection Topology (FPTO): Ewebata site na Yan et al., Usoro a na-akwado nha njirimara kacha nta (dịka ọmụmaatụ, 0.5 mm) ma na-ejikwa chamfer / gburugburu ọnụ iji kwalite nrụpụta.
Multi-Ebumnobi Optimization: Na-ejikọta nrụgide, nchụpụ, na ihe mgbochi iji kwalite geometry diaphragm maka oke nrụgide (dịka -80 kPa ruo -100 kPa).

Ọmụmaatụ: A 25-mm dayameta diaphragm kachasị site na ESO belatara ịta ahụhụ site na 45% ebe ị na-ejigide arụmọrụ oghere nke 92%.

3. Na-ekwu maka mmachi nrụpụta

Ụkpụrụ imewe maka nrụpụta (DFM) na-eme ka o kwe omume na ọnụ ahịa bara uru:

Opekempe njikwa ịdị arọ: Na-eme ka o doo anya nguzosi ike n'ezi ihe n'oge ịkpụzi ma ọ bụ mmepụta mgbakwunye. Algọridim dabere na FPTO na-enweta nkesa nha nha nha, na-ezere mpaghara ndị nwere ike ịda ada.
Mgbanwe nke oke: Usoro nzacha nke mgbanwe-radius na-ewepụ akụkụ dị nkọ, na-ebelata nrụgide nrụgide na imeziwanye ndụ ike ọgwụgwụ.
Nhazi modular: Ngalaba diaphragm a na-agbakọta nke ọma na-eme ka ntinye aka n'ime ụlọ mgbapụta, belata oge mgbakọ site na 50%.

4. Nkwado arụmọrụ site na ịme anwansị na nnwale

Ịkwado atụmatụ kachasị mma chọrọ nyocha siri ike:

Ntụle Element Izu (FEA): Na-ebu amụma nkesa nrụgide na nrụrụ n'okpuru ntinye cyclic. Ụdị FEA parametric na-enyere aka ngbanwe ngwa ngwa nke geometries diaphragm.
Nlele ike ọgwụgwụ: Nnwale ndụ accelerated (dịka, 10,000+ cycles na 20 Hz) na-akwado ịdịte aka, na nyocha Weibull na-ebu amụma ụdị ọdịda na ogologo ndụ.
Nnwale ọsọ na nrụgide: A na-enyocha ọkwa agụụ yana nkwụsi ike na-aga site na iji ụkpụrụ ọkọlọtọ ISO.

Nsonaazụ: A topology-kachasị mma diaphragm gosiri a 25% ogologo ndụ ndụ na 12% elu eruba nkwụsi ike tụnyere omenala aghụghọ.

5. Ngwa gafee ụlọ ọrụ

Nhazi diaphragm emebere nke ọma na-eme ka ọ pụta ìhè na mpaghara dị iche iche:

Ngwa ahụike: Mgbapu oghere na-eyi maka ọgwụgwọ ọnya, na-enweta -75 kPa suction na <40 dB mkpọtụ.
Ụlọ ọrụ mmepụta ihe: Igwe nfuli kọmpat maka rọbọtị na-ebu na ebe, na-ebuga ọnụego 8 L/min na ngwugwu 50-mm³.
Nleba anya gburugburu ebe obibi: Obere nfuli maka nlele ikuku, dakọtara na gas na-eme ihe ike dị ka SO₂ na NOₓ1.

6. Ntuziaka n'ọdịnihu

Usoro na-apụta na-ekwe nkwa ọganihu ọzọ:

Smart Diaphragms: Ihe mmetụta mgbaba agbakwunyere maka nleba anya ahụike na amụma amụma.
Nrụpụta mgbakwunye: 3D-ebipụtara diaphragms nwere gradient porosity maka emelitere mmiri ike.
Mbuli elu AI-chụpụrụ: Algọridim mmụta igwe iji nyochaa geometry na-enweghị nghọta gafere usoro topology ọdịnala.
