Akara igwe bụ ihe dị oke mkpa n'ime igwe ụlọ ọrụ mmepụta ihe, na-ahụ na ọ na-arụ ọrụ n'efu na nfuli, compressors, na akụrụngwa ntụgharị. Edemede a na-enyocha ụkpụrụ bụ isi nke akara igwe, ụdị ha, ihe na ngwa ha n'ofe ụlọ ọrụ dị iche iche. Na mgbakwunye, ọ na-atụle ụdị ọdịda a na-ahụkarị, omume mmezi na ọganihu na teknụzụ akara. Site n'ịghọta akụkụ ndị a, ụlọ ọrụ nwere ike ịkwalite ntụkwasị obi akụrụngwa, belata oge nkwụsị, ma melite arụmọrụ arụmọrụ.

1. Okwu mmalite

Akara igwe bụ ngwaọrụ eji arụ ọrụ nkenke emebere iji gbochie mmiri na-agbapụta n'ime akụrụngwa na-atụgharị dịka nfuli, igwekota, na compressors. N'adịghị ka mbukota gland ọdịnala, akara igwe na-enye arụmọrụ dị elu, mbelata esemokwu, yana ogologo ndụ ọrụ. Nkuchi ha juru ebe niile na ụlọ ọrụ dịka mmanụ na gas, nhazi kemịkalụ, ọgwụgwọ mmiri, na ike ọkụ na-egosipụta mkpa ha dị na ọrụ ụlọ ọrụ ọgbara ọhụrụ.

Edemede a na-enye nkọwa zuru oke nke akara igwe, gụnyere usoro ọrụ ha, ụdị, nhọrọ ihe, na ngwa ụlọ ọrụ. Ọzọkwa, ọ na-enyocha ihe ịma aka dị ka ọdịda akara na atụmatụ mmezi iji hụ na arụmọrụ kacha mma.

2. Isi ihe nke Mechanical Seals

2.1 Nkọwa na Ọrụ

Akara igwe bụ ngwaọrụ na-emepụta ihe mgbochi n'etiti ogwe na-atụgharị na ụlọ kwụ ọtọ, na-egbochi mmiri mmiri na-agbapụta ma na-enye ohere ntụgharị dị nro. Ọ nwere isi ihe abụọ:

  • Ihu mkpuchi nke izizi: Ihu akara na-agbanwe agbanwe nke na-adị na nso nso.
  • Akara nke abụọ: O-mgbanaka, gaskets, ma ọ bụ elastomers na-egbochi ntapu n'akụkụ ihu akara.

2.2 Ụkpụrụ ọrụ

Akara igwe eji arụ ọrụ na-arụ ọrụ site na idowe ihe nkiri dị nro dị nro n'etiti ihu mkpuchi, na-ebelata esemokwu na iyi. Nguzozi n'etiti nrụgide mmiri na ibu mmiri na-eme ka ihu ihu dị mma, na-egbochi nkwụsị. Isi ihe na-emetụta arụmọrụ akara gụnyere:

  • Ihu dị larịị: Na-eme ka kọntaktị otu.
  • Ngwucha elu: Na-ebelata esemokwu na mmepụta okpomọkụ.
  • Ndakọrịta ihe: Na-eguzogide mmebi kemịkalụ na thermal.

3. Ụdị Akara Mechanical

A na-ekewa akara akara igwe dabere na nhazi, ngwa na ọnọdụ ọrụ.

3.1 Kwesịrị ekwesị vs. Akara na-enweghị atụ

  • Akara Kwesịrị Ekwesị: Jikwaa nrụgide dị elu site na ibelata ibu hydraulic na ihu akara.
  • Akara na-ezighi ezi: Kwesịrị ekwesị maka ngwa nrụgide dị ala mana ọ nwere ike ịnwe oke iyi.

3.2 Pusher vs. Akara na-abụghị Pusher

  • Akara Pusher: Jiri akara nke abụọ siri ike na-agagharị axially iji kwado ihu ihu.

3.3 Single vs. Ugboro abụọ Akara

  • Otu Akara Akara: Otu setịpụ ihu mkpuchi, dị ọnụ ahịa maka mmiri mmiri na-adịghị ize ndụ.
  • Akara Ugboro Abụọ: Ụdị ihu abụọ nwere mmiri mgbochi, ejiri ya maka ngwa nsi ma ọ bụ nnukwu nrụgide.

3.4 Cartridge vs.Akara akụrụngwa

  • Akara Cartridge: Nkeji a kpọkọtara tupu oge eruo maka nrụnye dị mfe na nnọchi.
  • Akara akụrụngwa: Akụkụ nke ọ bụla chọrọ nhazi nke ọma.

4. Nhọrọ ihe maka Mechanical Akara

Nhọrọ nke ihe na-adabere na ndakọrịta mmiri, okpomọkụ, nrụgide, na nkwụsị nke abrasion.

4.1 Ihe mkpuchi ihu

  • Carbon-Graphite: Njirimara mmanye onwe ya mara mma.
  • Silicon Carbide (SiC): Igwe ọkụ dị elu ma na-eyi nguzogide.
  • Tungsten Carbide (WC): Ọ na-adịgide adịgide mana enwere ike ibute ọgụ kemịkal.
  • Ceramics (Alumina): nrụrụ na-eguzogide ma kenkuwa.

4.2 Elastomers naAkara nke abụọ

  • Nitrile (NBR): Mmanụ na-eguzogide, ejiri na ngwa ebumnuche izugbe.
  • Fluoroelastomer (FKM): Nnukwu kemịkalụ na nguzogide okpomọkụ.
  • Perfluoroelastomer (FFKM): ndakọrịta kemịkalụ dị oke.
  • PTFE: Inert na ọtụtụ kemịkalụ mana obere mgbanwe.

5. Ngwa ụlọ ọrụ nke Mechanical Seals

5.1 Ụlọ ọrụ mmanụ na gas

Akara igwe dị mkpa na nfuli, compressors, na turbines na-ejikwa mmanụ crude, gas sitere n'okike, na ngwaahịa a nụchara anụcha. Akara okpukpu abụọ nwere mmiri mgbochi na-egbochi mmiri nke hydrocarbon, na-ahụ maka nchekwa na nnabata gburugburu ebe obibi.

5.2 Nhazi kemịkalụ

Kemịkal na-eme ihe ike chọrọ akara na-eguzogide corrosion nke silicon carbide ma ọ bụ PTFE. Igwe nfuli draịva magnetik nwere akara hermetic na-ewepụ ihe egwu dị n'ịnyịnya.

5.3 Ọgwụgwọ mmiri na mmiri mkpofu

Igwe nfuli centrifugal na osisi ọgwụgwọ na-eji akara igwe iji gbochie mmetọ mmiri. Ihe na-eguzogide abrasion na-agbatị ndụ akara na ngwa slurry.

5.4 Ike Ọgbọ

N'ime igwe ikuku uzuoku na sistemu jụrụ oyi, akara igwe na-arụ ọrụ nke ọma site na igbochi uzuoku na ntapu mmiri oyi. Alloys okpomọkụ dị elu na-eme ka a pụrụ ịdabere na ya na osisi okpomọkụ.

5.5 Ụlọ ọrụ nri na ọgwụ

Akara igwe ọcha na ihe ndị FDA kwadoro na-egbochi mmetọ na akụrụngwa nhazi. Ndakọrịta dị ọcha na ebe (CIP) dị mkpa.

6. Ụdị ọdịda nkịtị na nchọpụta nsogbu

6.1 Akara mkpuchi ihu

  • Ihe na-akpata: mmanye mmanye na-adịghị mma, nhazi ihe na-adịghị mma, ihe abrasive.
  • Ngwọta: Jiri ihe ihu siri ike, kwalite nzacha.

6.2 Thermal mgbawa

  • Ihe na-akpata: mgbanwe okpomọkụ ngwa ngwa, akọrọ na-agba ọsọ.
  • Ngwọta: Gbaa mbọ hụ na jụrụ oyi nke ọma, jiri ihe kwụsiri ike na-ekpo ọkụ.

6.3 Mwakpo Chemical

  • Ihe kpatara ya: Ihe mkpuchi na-adabaghị adaba.
  • Ngwọta: Họrọ elastomers na ihu na-eguzogide ọgwụ.

6.4 Mmehie nwụnye

  • Ihe kpatara ya: Ndozi na-ezighi ezi, imechi na-ezighi ezi.
  • Ngwọta: Soro ntuziaka ndị nrụpụta, jiri ngwaọrụ nkenke.

7. Nlekọta na Omume kacha mma

  • Nyocha oge niile: Nyochaa maka ntapu, ịma jijiji na mgbanwe okpomọkụ.
  • mmanu mmanu: Gbaa mbọ hụ na ihe nkiri mmiri zuru oke n'etiti ihu akara.
  • Nwụnye ziri ezi: Dozie osisi nke ọma iji gbochie eyi na-enweghị isi.
  • Nleba anya ọnọdụ: Jiri sensọ chọpụta akara ọdịda mbụ.

8. Ọganihu na Mechanical Seal Technology

  • Akara Smart: Akara aka IoT nwere nleba anya ozugbo.
  • Akụrụngwa dị elu: Nanocomposites maka ịdịte aka emelitere.
  • Akara mmanụ mmanụ gas: Belata esemokwu n'ime ngwa ọsọ dị elu.

9. Nkwubi okwu

Akara igwe na-arụ ọrụ dị mkpa na arụ ọrụ ụlọ ọrụ site n'ịkwalite ntụkwasị obi akụrụngwa yana igbochi ntapu dị ize ndụ. Ịghọta ụdị ha, ihe na ngwa ha na-enye ohere ka ụlọ ọrụ na-ebuli arụmọrụ ma belata ụgwọ ọrụ. Site n'ọganihu na-aga n'ihu, akara igwe ga-aga n'ihu na-etolite, na-egbo mkpa nke usoro mmepụta ihe ọgbara ọhụrụ.

Site na itinye usoro kachasị mma na nhọrọ, nrụnye, na nrụzi, ụlọ ọrụ nwere ike ịbawanye ogologo ndụ nke akara igwe, na-ahụ na arụmọrụ dị mma na nchekwa.
