Piston kasa compressors (reciprocating compressors) ua avea ma meafaigaluega autu i le gaosiga o le kesi compressors ona o latou gaosiga maualuga-omiga, pulea fetuutuunai, ma tulaga ese le faatuatuaina. O lenei tusiga o loʻo faʻamalamalamaina lelei o latou tulaga faʻapitoa i faʻataʻitaʻiga faʻapipiʻi kesi e tele, faʻavae i luga o faʻavae mamanu faʻavae.
I. Fuafuaga Autu
O le fa'atinoga o piston gas compressors e afua mai i se faiga fa'amaopoopo fa'atasi, e aofia ai vaega taua nei:
1. Fonotaga Sili-Malosi Sili
Fausia mai le u'amea, u'amea u'amea, po'o mea fa'apipi'i fa'apitoa e fa'asalaina ai le a'a umi mai ala fa'asalalau fa'amalosi e pei o kasa oona (eg, H₂S) ma le okesene maualuga.
Fa'amuta vai/suau'u tu'ufa'atasia e fa'amanino lelei suiga o le vevela e mafua mai i mea kesi (fa'ata'ita'iga, maualalo le viscosity o le hydrogen, maualuga le gaioiga o le ammonia).
2. Tele-Material Piston Fonotaga
Piston Crown: Filifiliga mea e fa'atatau i kemisi kesi—fa'ata'ita'iga, 316L u'amea u'amea mo le sulfur-o lo'o i ai le kasa e tete'e, ufiufi sima mo siosiomaga maualuga CO₂.
Faiga Fa'amauga Fa'amau: Fa'aaogaina graphite, PTFE, po'o fa'amaufa'ailoga u'amea tu'ufa'atasi e puipuia ai le fa'aosoina o kasa maualuga maualuga (fa'ata'ita'iga, helium, methane), fa'amautinoa le lelei o le fa'amalosi ≥92%.
3. Faiga Valve atamai
Fa'ato'a fa'afetaui le taimi o le fa'aulu/usu ma si'i ina ia fa'aogaina le tele o kasa ma fua fa'amalosi (fa'ata'ita'iga, nitrogen ile 1.5:1 ile hydrogen ile 15:1).
O pa'u pa'u fa'afefete le vaivai e tumau i le uila vilivae maualuga (≥1,200 ta'amilosaga/minute), fa'alautele taimi fa'aleleia i si'osi'omaga kesi mu/pa.
4. Modular Compression Unit
Lagolagoina fetuutuunai fetuutuunai 2- i le 6-laasaga compression configurations, faatasi ai ma le tasi-laasaga mamafa e oo atu i le 40-250 pa, ausia manaoga eseese mai inert kesi teuina (faataitaiga, argon) i syngas pressurization (faataitaiga, CO+H₂).
O feso'ota'iga feso'ota'i vave e mafai ai ona fetu'una'i faiga fa'a'alili vave e fa'atatau i ituaiga kesi (fa'ata'ita'iga, fa'amalulu vai mo le acetylene, fa'amalulu suau'u mo Freon).
II. Fa'amanuiaga Fa'atatauga Gaoioiga Gas
1. Atoatoa Fa'asalalauga Felagolagomai
Kasa Mata'utia: Mea fa'alelei (fa'ata'ita'iga, Hastelloy cylinders, titanium alloy piston rods) ma le fa'ama'a'a o luga e fa'amautinoa ai le tumau i totonu o si'osi'omaga e tele le sulfur ma halogen.
Kasa maualuga-mama: lubrication e leai se suauu ma ultra-saʻo filtration ausia ISO 8573-1 Vasega 0 mama mo eletise-grade nitrogen ma okesene faafomai.
Kasa mu/Papa: Fa'amalieina fa'amaoniaga ATEX/IECEx, fa'apipi'iina ma fa'agata ai aloiafi ma fa'afefete fete'ena'iga mo le tagofiaina saogalemu o le hydrogen, okesene, CNG, ma le LPG.
2. Adaptive Gaioioiga Gafatia
Laulau Lautele: Ta'avale felafolafoa'i ma fetuutuunaiga o le kilia e mafai ai ona pulea le tafe laina (30%-100%), talafeagai mo le gaosiga fa'afuase'i (fa'ata'ita'iga, le toe fa'aleleia o le manava o le fale kemisi) ma le fa'aauau pea o le sapalai (fa'ata'ita'iga, iunite vaeluaga o le ea).
Pulea Atamai: Fa'apipi'i masini tu'ufa'atasiga tu'ufa'atasiga e otometi ona fetu'una'i ta'otoga (fa'ata'ita'iga, fa'alava o le vevela, fua ole lubrication) e puipuia ai fa'aletonu e mafua mai i suiga fa'afuase'i o meatotino.
3. Ta'amilosaga o le Soifuaga Lelei Tau
Fuafuaga Tausiga Maualalo: Fa'ateleina le ola o vaega taua e> 50% (fa'ata'ita'iga, 100,000-itula taimi fa'aleleia o le crankshaft), fa'aitiitia taimi fa'aletonu i si'osi'omaga mata'utia.
Fa'aleleia o Malosiaga: Fa'apipi'i pupuni e fa'atatau i fa'ailoga adiabatic fa'apitoa o kesi (k-values) maua le 15%-30% fa'asao malosi pe a fa'atusatusa i fa'ata'ita'iga masani. O fa'ata'ita'iga e aofia ai:
Ea fa'amalosi: Malosi fa'apitoa ≤5.2 kW/(m³/min)
Fa'aola kesi fa'alenatura: Fa'asao lelei ≥75%
III. Talosaga Autu Alamanuia
1. Kasa Fa'ainisinia (Oxygen/Nitrogen/Argon)
I metallurgy u'amea ma semiconductor gaosiga, suau'u-saoloto mamanu ma molecular sieve mulimuli-togafitiga mautinoa 99.999% mama mo talosaga e pei uʻamea talipupuni uʻamea ma faga fau.
2. Kasa Malosi (Hydrogen/Syngas)
Fa'apipi'i fa'atele-vaega (e o'o i le 300 pa) fa'atasi ma faiga fa'alavelave fa'alavelave e fa'aogaina saogalemu ai le hydrogen ma le carbon monoxide i le teuina o le malosi ma le fa'aogaina o vaila'au.
3. Kasa Mata'utia (CO₂/H₂S)
O vaifofo fa'apitoa e tete'e a'a-fa'ata'ita'iga, fa'alavalava tungsten carbide ma lubricant-tete'e fa'ama'i-tulaga i le sulfur-oa, maualuga-sūsū tulaga i le suau'u toe tu'iina ma le pu'eina kaponi.
4. Kasa Fa'aeletonika Fa'apitoa (Fluorinated Compounds)
Faiga fa'amaufa'ailoga atoa ma le su'esu'eina o le leki (leak rate <1×10⁻⁶ Pa·m³/s) fa'amautinoa le saogalemu o le fa'aogaina o kasa mata'utia e pei o le tungsten hexafluoride (WF₆) ma le nitrogen trifluoride (NF₃) i fale gaosi ata ma IC.
IV. Si'itia Fa'atekonolosi Fou
Faiga Fa'akomepiuta Twin: O fa'ata'ita'iga fa'amaumauga i taimi tonu e va'ai ai le ofuina o mama piston ma le fa'aletonu o le valve, e mafai ai ona fa'ailoa le tausiga i le 3-6 masina muamua atu.
Fa'atasiga Fa'ameamatamata: Fa'aliliuina e vaega o le vevela o otaota le 70% o le vevela fa'amalosi i le ausa po'o le eletise, e lagolagoina sini fa'aleaogaina o le carbon neutrality.
Ultra-High-Pressure Breakthroughs: Tekinolosi faʻamalo faʻamalo muamua e ausia ai le faʻapipiʻiina o le tulaga tasi> 600 pa i totonu o fale suʻesuʻe, saunia le ala mo le teuina ma le felauaiga o le hydrogen i le lumanaʻi.
Fa'ai'uga
Piston gas compressors, faʻatasi ai ma o latou fausaga faʻapitoa ma agavaʻa faʻapitoa, e tuʻuina atu fofo faʻatuatuaina mo le gaosiga o kesi fale gaosi oloa. Mai le fa'apipi'i masani e o'o atu i le fa'aogaina o kesi fa'apitoa fa'apitoa, o fa'atonuga fa'atulagaina e mautinoa ai le saogalemu, lelei, ma le taugofie o galuega.
Mo ta'iala filifilia compressor po'o lipoti fa'amaonia fa'atekinisi e fa'atatau i fa'asalalauga kesi fa'apitoa, fa'amolemole fa'afeso'ota'i la matou 'au fa'ainisinia.
Fa'amatalaga Fa'atekinisi:
Fa'amaumauga e maua mai le ISO 1217, API 618, ma isi fa'ata'ita'iga fa'ava-o-malo.
E ono fesuisuia'i la'ititi le fa'atinoga moni e fa'atatau ile tu'ufa'atasiga o kesi ma tulaga tau si'osi'omaga.
O le fa'atulagaina o meafaigaluega e tatau ona ogatasi ma tulafono fa'alotoifale mo le saogalemu mo masini fa'apitoa.
