Ngwakọta gas Piston (compressors na-agbanwe agbanwe) aghọọla akụrụngwa dị mkpa na nrụgide gas ụlọ ọrụ n'ihi mmepụta ha dị elu, njikwa mgbanwe, na ntụkwasị obi pụrụ iche. Isiokwu a na-akọwapụta uru teknụzụ ha na ọnọdụ nrụgide gas dị iche iche, dabere na ụkpụrụ nhazi usoro.
I. Nhazi ihe owuwu isi
Arụmọrụ nke piston gas compressors sitere na sistemụ akụkụ a haziri nke ọma, gụnyere akụkụ ndị a dị mkpa:
1. Mgbakọ Silinda Dị Ike
E ji ígwè a kpụrụ akpụ, ígwè alloy, ma ọ bụ ihe mkpuchi pụrụ iche rụọ ya iji guzogide mmebi ogologo oge site na ihe siri ike dịka gas acidic (dịka ọmụmaatụ, H₂S) na oxygen nwere nrụgide dị elu.
Ọwa mmiri na mmanụ jikọtara ọnụ iji jikwaa mgbanwe okpomọkụ nke ihe ndị na-akpata gas (dịka ọmụmaatụ, obere viscosity nke hydrogen, nnukwu mmeghachi omume nke ammonia).
2. Mgbakọ Piston nke nwere ọtụtụ ihe
Okpu Piston: Nhọrọ ihe e ji mee ihe dabere na kemịkalụ gas—dịka ọmụmaatụ, ígwè anaghị agba nchara 316L maka iguzogide nchara gas nke nwere sọlfọ, mkpuchi seramiiki maka gburugburu CO₂ dị elu.
Sistemụ Mgbaaka Mkpuchi: A na-eji akara graphite, PTFE, ma ọ bụ ihe mejupụtara ígwè iji gbochie mmiri nke gas nrụgide dị elu (dịka ọmụmaatụ, helium, methane), na-eme ka arụmọrụ mkpakọ dị mma ≥92%.
3. Sistemụ Valvụ Ọgụgụ Isi
Na-agbanwe oge valvụ oriri/ikuku na ebuli ya nke ọma iji kwekọọ njupụta gas na oke mkpakọ dị iche iche (dịka ọmụmaatụ, nitrogen na 1.5:1 ruo hydrogen na 15:1).
Efere valvụ ndị na-anaghị akpata ike ọgwụgwụ na-anagide usoro ịgbagharị ugboro ugboro (≥1,200 okirikiri kwa nkeji), na-agbatị oge mmezi n'ebe gas na-ere ọkụ/na-agbawa agbawa.
4. Ngalaba Mkpakọ Modular
Na-akwado nhazi mkpakọ nke ọkwa abụọ ruo isii na-agbanwe agbanwe, yana nrụgide otu ogbo ruo ogwe 40–250, na-egbo mkpa dị iche iche site na nchekwa gas na-adịghị arụ ọrụ (dịka ọmụmaatụ, argon) ruo nrụgide syngas (dịka ọmụmaatụ, CO+H₂).
Njikọ ngwa ngwa na-eme ka mgbanwe sistemụ oyi ngwa ngwa dabere na ụdị gas (dịka ọmụmaatụ, mmiri oyi maka acetylene, mmanụ oyi maka Freon).
II. Uru Ndakọrịta Gas Ụlọ Ọrụ
1. Ndakọrịta zuru oke nke mgbasa ozi
Gas ndị na-emebi emebi: Ihe ndị e ji aka mee (dịka ọmụmaatụ, silinda Hastelloy, mkpara piston titanium alloy) na ime ka elu sie ike na-eme ka ọ dịgide ogologo oge n'ebe jupụtara na sọlfọ na halogen.
Gas Dị Ọcha Dị Elu: Mmanụ na-enweghị mmanụ na nzacha nke ọma na-eme ka ISO 8573-1 Klas 0 dị ọcha maka nitrogen na oxygen ahụike.
Gas ndị na-ere ọkụ/na-agbawa agbawa: Na-agbaso asambodo ATEX/IECEx, e ji ihe mgbochi ọkụ na ihe mgbochi mgbanwe nrụgide mee ihe maka ijikwa hydrogen, oxygen, CNG, na LPG nke ọma.
2. Ike Ọrụ Mgbanwe
Oke Njem Njem: draịva ugboro ole na-agbanwe agbanwe na mgbanwe olu nkesa na-eme ka njikwa usoro mmiri kwụ ọtọ (30%–100%), nke dabara adaba maka mmepụta oge ụfọdụ (dịka ọmụmaatụ, mgbake ikuku sitere na osisi kemịkalụ) na inye ihe na-aga n'ihu (dịka ọmụmaatụ, nkeji nkewa ikuku).
Njikwa Amamihe: Ihe mmetụta nhazi gas ejikọtara na-agbanwe paramita na-akpaghị aka (dịka ọmụmaatụ, oke okpomọkụ, ọnụego mmanụ) iji gbochie nsogbu nke mgbanwe ihe onwunwe gas na mberede kpatara.
3. Nhazi Ọnụ Ego Ndụ
Nhazi Mmezi Dị Ala: Ndụ akụkụ dị mkpa na-agbatị site na >50% (dịka ọmụmaatụ, oge mmezi crankshaft awa 100,000), na-ebelata oge ọrụ na gburugburu ebe dị ize ndụ.
Nhazi Ike: Usoro mkpakọ nke e mere ka ọ dabara na ihe ngosi adiabatic (k-values) nke gas na-enye nchekwa ike site na 15% ruo 30% ma e jiri ya tụnyere ihe nlereanya nkịtị. Ihe atụ gụnyere:
Ikuku a gbakọrọ agbakọ: Ike kpọmkwem ≤5.2 kW/(m³/min)
Mmelite gas sitere n'okike: arụmọrụ isothermal ≥75%
III. Ngwa Ụlọ Ọrụ Dị Mkpa
1. Gas ụlọ ọrụ nkịtị (Oxygen/Nitrogen/Argon)
N'ime ụlọ ọrụ ígwè na mmepụta semiconductor, atụmatụ ndị na-enweghị mmanụ nwere sieve molekul mgbe ọgwụgwọ gasịrị na-eme ka ọ dị ọcha 99.999% maka ngwa dịka ihe mkpuchi ígwè gbazere agbaze na imepụta wafer.
2. Gas Ike (Hydrogen/Syngas)
Mkpakọ dị iche iche (ruo 300 bar) yana sistemụ mgbochi mgbawa na-ejikwa hydrogen na carbon monoxide eme ihe n'enweghị nsogbu na nchekwa ike na mmepụta kemịkalụ.
3. Gas ndị na-emebi emebi (CO₂/H₂S)
Ngwọta ahaziri ahazi nke na-eguzogide nchara—dịka ọmụmaatụ, mkpuchi tungsten carbide na mmanụ na-eguzogide acid—na-edozi ọnọdụ mmiri dị elu nke jupụtara na sọlfọ, nke nwere oke iru mmiri na ntinye mmanụ na njide carbon.
4. Gas Elektrọniki Pụrụ Iche (Ihe Ndị A Na-eji Fluorin Mee)
Nchọpụta nke ọma gbasara nrụpụta na nchọpụta mmiri helium mass-spectrometer (ọnụọgụ mmiri <1×10⁻⁶ Pa·m³/s) na-eme ka a hụ na a na-ejikwa gas ndị dị ize ndụ dịka tungsten hexafluoride (WF₆) na nitrogen trifluoride (NF₃) n'ụlọ ọrụ fotovoltaic na IC nke ọma.
IV. Ọganihu Teknụzụ Ọhụrụ
Sistemụ Ejima Dijitalụ: Nhazi data oge a na-ebu amụma mmebi mgbanaka piston na ọdịda valvụ, na-eme ka ịdọ aka ná ntị mmezi dị irè ọnwa 3-6 tupu oge eruo.
Njikọta Usoro Akwụkwọ Ndụ: Ngalaba mgbake okpomọkụ mkpofu na-agbanwe 70% nke okpomọkụ mkpakọ ka ọ bụrụ uzuoku ma ọ bụ ọkụ eletrik, na-akwado ebumnuche nke nnọpụiche carbon.
Ihe Ndị Dị Mkpa Na-eme Ka Ọ Dị Elu: Teknụzụ silinda a na-agbagharị agbagharị nke e tinyere nrụgide tupu oge eruo na-enweta mkpakọ otu ogbo karịrị 600 bar na ntọala ụlọ nyocha, na-emeghe ụzọ maka nchekwa na mbufe hydrogen n'ọdịnihu.
Mmechi
Ngwakọta gas Piston, nke nwere usoro nhazi modular na ikike nhazi ha, na-enye ngwọta a pụrụ ịdabere na ya maka nhazi gas ụlọ ọrụ mmepụta ihe. Site na nrụgide oge niile ruo na njikwa gas pụrụ iche nke dị oke njọ, nhazi nhazi na-eme ka ọrụ dị nchebe, dị irè, na dị ọnụ ala.
Maka ntuziaka nhọrọ compressor ma ọ bụ akụkọ nkwenye teknụzụ nke ahaziri maka mgbasa ozi gas pụrụ iche, biko kpọtụrụ ndị otu injinia anyị.
Ihe Ndetu Nkà na ụzụ:
Data sitere na ISO 1217, API 618, na ụkpụrụ nnwale mba ụwa ndị ọzọ.
