Njengegesi yokukhusela engasebenziyo, ngaba i-nitrogen inomngcipheko "wokunyibilika" ngexesha lokucinezelwa? Ungayiphepha njani ngoyilo lwenkqubo?

I-nitrogen isetyenziswa kakhulu njengegesi yokukhusela engasebenziyo kwiinkqubo ezininzi zoshishino—ukusuka kwiingubo zeekhemikhali kunye nokupakisha ukutya ukuya kwimveliso ye-elektroniki kunye nonyango lobushushu besinyithi. Ngenxa yokuba i-nitrogen ayitshi kwaye ayisebenzi kwizinto ezininzi, idla ngokuthathwa njengegesi "elula" ukuyicinezela. Nangona kunjalo, iinjineli kunye nabaqhubi bezityalo ngamanye amaxesha babuza umbuzo obalulekileyo: Ngaba i-nitrogen ingayinyibilikisa ngaphakathi kwi-compressor ngexesha lokusebenza okuqhelekileyo? Kwaye ukuba kunjalo, zeziphi iingozi ezibangelwa koko, kwaye uyilo olufanelekileyo lwe-compressor kunye nolawulo lwenkqubo lungayithintela njani?

Eli nqaku lichaza iimeko zomzimba apho i-nitrogen inokutshintsha khona ulwelo, kwaye kutheni oko kuyingozi kwi-isixinizelelo senitrogen, kunye nokuba zeziphi iindlela zoyilo kunye neendlela zokusebenza ezigcina inkqubo yokucinezelwa ngokukhuselekileyo kwisigaba segesi.

I-nitrogen inyibilika xa iphantsi koxinzelelo kunye nobushushu obungakanani?

I-nitrogen ayisiyogesi "ehlala ihleli" ngeyona ndlela ingqongqo—inokunyibilikiswa ukuba ipholiswe ngaphantsi kobushushu bayo obubalulekileyo kwaye iphantsi koxinzelelo olwaneleyo. Ubushushu obubalulekileyo be-nitrogen bumalunga ne--147 °C (-233 °F). Ngaphezulu kobu bushushu, akukho xinzelelo lunokunyusa i-nitrogen; iya kuhlala ingulwelo okanye igesi ebaluleke kakhulu. Ngaphantsi kwe--147 °C, i-nitrogen inokujiya ibe lulwelo xa uxinzelelo ludlula uxinzelelo lwayo lomphunga.

Kwi-compression eqhelekileyo yemizi-mveliso, i-nitrogen ingena kwi-compressor kubushushu obuqhelekileyo (ngokuqhelekileyo i-20–40 °C) kwaye ikhutshwa kubushushu obuphezulu (ngokuqhelekileyo i-100–150 °C). Kuyo yonke le nkqubo, ubushushu begesi buhlala bungaphezulu kakhulu kwe-147 °C. Ke ngoko, phantsi kweemeko zokusebenza eziqhelekileyo, akukho mngcipheko wokuba i-nitrogen inyibilike ngaphakathi kwi-compressor, nokuba uxinzelelo luphakama kangakanani na.

Kutheni ke ubuza lo mbuzo?

Ingxaki idla ngokuvela kwiimeko ezimbini:

1. Ukuqala kokubanda okanye amaqondo obushushu aphantsi kakhulu: Ukuba i-compressor ikwimeko ebanda kakhulu (umz., iimeko ze-Arctic) kwaye umthombo we-nitrogen nawo ubanda kakhulu, igesi ingangena kwi-compressor kumaqondo obushushu asondela kwi--50 °C okanye ngaphantsi. Nangona isengaphezulu kakhulu kwi--147 °C, ezinye iinjineli zixhalabile ngemiphumo yokupholisa yendawo.
2. Ukupholisa okwandisiweyo: Xa igesi ecinezelweyo isanda ngevalvu okanye i-orifice (umz., ngexesha lokunciphisa uxinzelelo), ubushushu bayo buyehla kakhulu (isiphumo seJoule-Thomson). Ukuba i-nitrogen exinezelekileyo isanda ngequbuliso ukuya kuxinzelelo oluphantsi, ubushushu bunokwehla ngaphantsi kwe--147 °C, nto leyo ebangela ukunyibilika kolwelo. Oku akwenzeki.ngaphakathiigumbi lokucinezelwa kwecompressor kodwa linokwenzeka ngezantsi, umzekelo, kwisikhululo sokunciphisa uxinzelelo okanye kwinkqubo ye-cryogenic.

Ngaphakathi kwi-nitrogen compressor eyilwe kakuhle—akukho mngcipheko

Kwi-compressor ye-nitrogen esebenza ngaphakathi kwemilinganiselo yayo yoyilo, ubushushu begesi abufiki kwinqanaba elibalulekileyo. Ubushushu bokukhupha umoya buhlala buphakathi kwe-120 °C kunye ne-150 °C ukuze kukhuseleke kwaye kuhlale ixesha elide lokuthambisa (kwiimodeli ezithanjiswe nge-lubricant). Nokuba kuxinzelelo olufikelela kwi-350 bar okanye ngaphezulu, i-nitrogen ihlala ingulwelo okanye igesi ebaluleke kakhulu, hayi ulwelo. Ke ngoko, umonakalo woomatshini ovela kwimpembelelo yolwelo (ukutshixa kwe-hydraulic) okanye ukufuma kwangaphakathi akuyongxaki kwinkonzo eqhelekileyo yokucinezela i-nitrogen.

Ingxaki ingaba nini ukunyibilika kolwelo? Kwaye ungayiphepha njani?

Nangona ukunyibilika ngaphakathi kwi-compressor kungengomngcipheko onokwenzeka, kukho iimeko ezimbini zenkqubo apho i-nitrogen engamanzi inokwenzeka kwinkqubo ye-compressor, kwaye ezi zifuna uyilo olucokisekileyo:

1. Ukupholisa phakathi kwesiteji kunye namaqondo obushushu aphantsi kakhulu okupholisa
Ukuba icompressor inee-intercoolers ezisebenzisa i-refrigerant okanye amanzi abandayo ukupholisa igesi phakathi kwezigaba, kunokwenzeka ukuba ipholise i-nitrogen kakhulu. Ukuba ubushushu begesi emva kwe-intercooler buyehla ngaphantsi komphetho womswakama (ukuba ukhona), ukufuma kwamanzi kuyingozi. Kodwa kwi-nitrogen ecocekileyo neyomileyo, i-intercooler kuya kufuneka ipholise igesi ngaphantsi kwe--147°C ukuze ibangele ukunyibilika—nto leyo engenzekiyo kwimizi-mveliso.

• Ukuphepha: Sebenzisa umoya ojikeleze umhlaba okanye amanzi aqhelekileyo okupholisa (hayi amanzi abandayo) ukuze upholise ngaphakathi. Misela amazinga okuhamba kwe-coolant ukuze ugcine amaqondo obushushu egesi ephumayo engaphezulu kwe-0 °C (okanye ngaphezulu kwe-147 °C, nto leyo eyenzeka ngokuzenzekelayo).

2. Ukwanda koxinzelelo oluphezulu ngezantsi
Ukuba i-nitrogen ecinezelweyo igcinwa kuxinzelelo oluphezulu ize yandiswe ukuya kuxinzelelo oluphantsi kakhulu ngevalvu (umzekelo, kwisikhululo sokuzalisa isilinda segesi okanye kwindawo yokutyibiliza uxinzelelo), ukwehla kobushushu kunokubangela ukubanda komswakama okanye nokuba yi-nitrogen enyibilikayo ukuba ukwehla koxinzelelo kugqithisile kwaye ubushushu bokuqala buphantsi kakhulu.

• Ukuphepha: Fudumeza i-nitrogen ngaphambi kokuba ikhule okanye usebenzise amanqanaba amaninzi okwandisa ngokuphinda uyifudumeze. Faka isahluli solwelo lomphunga ngezantsi ukuba kukho umngcipheko wokuba ulwelo ludlulele ngaphaya kwayo.

Kutheni ukukhetha i-compressor ngokufanelekileyo kunye noyilo lwenkqubo kubalulekile?

Inkqubo ye-nitrogen compressor eyilwe kakuhle kufuneka:

• Gcina amaqondo obushushu egesi ekhuselekile ngaphezu kweyona ndawo ibalulekileyo (ezenzekela ngokuzenzekelayo kwiimeko ezingqongileyo).
• Sebenzisa ukupholisa okungapholisi kakhulu igesi (umz., ii-intercoolers ezinobukhulu obufanelekileyo ezinolawulo lobushushu).
• Faka izikhonkwane zokhuseleko ezivala i-compressor ukuba amaqondo obushushu okukhupha amanzi aphantsi kakhulu (akunakwenzeka) okanye aphezulu kakhulu.
• Kwiindawo ezibandayo kakhulu, cinga ngeendawo zokufudumeza igesi yokungenisa okanye amagumbi okufudumeza afudumeleyo ukuze kugcinwe amaqondo obushushu angaphezulu kwe--20°C.
