Monga mpweya woteteza wopanda mphamvu, kodi nayitrogeni ili ndi chiopsezo cha "kusungunuka" panthawi yoponderezedwa? Kodi mungapewe bwanji kudzera mu kapangidwe kake?

Nayitrogeni imagwiritsidwa ntchito kwambiri ngati mpweya woteteza m'mafakitale ambiri—kuyambira kuphimba ndi mankhwala ndi kulongedza chakudya mpaka kupanga zamagetsi ndi kutentha kwachitsulo. Popeza nayitrogeni siiyaka ndipo sigwirizana ndi zinthu zambiri, nthawi zambiri imaonedwa ngati mpweya "wosavuta" kuponderezedwa. Komabe, mainjiniya ndi ogwira ntchito m'mafakitale nthawi zina amafunsa funso lofunika: Kodi nayitrogeni ingasungunukedi mkati mwa compressor panthawi yogwira ntchito nthawi zonse? Ndipo ngati ndi choncho, kodi zimenezo zimayambitsa zoopsa zotani, ndipo kodi kapangidwe koyenera ka compressor ndi kuwongolera njira kungalepheretse bwanji?

Nkhaniyi ikufotokoza za momwe nayitrogeni imakhalira madzi, chifukwa chake izi ndi zoopsa kwakompresa wa nayitrogeni, ndi njira zotani zopangira ndi kugwiritsa ntchito zomwe zimasunga njira yochepetsera mpweya bwino mu gawo la mpweya.

Kodi nayitrogeni imasungunuka pa kutentha ndi mphamvu yotani?

Nayitrogeni si mpweya "wosatha" kwenikweni—ungathe kusungunuka ngati utaziziritsidwa pansi pa kutentha kwake kofunikira ndikukakamizidwa mokwanira. Kutentha kofunikira kwa nayitrogeni ndi pafupifupi -147 °C (-233 °F). Kupitirira kutentha kumeneku, palibe kupanikizika komwe kungasungunule nayitrogeni; idzakhalabe madzi kapena mpweya wofunikira kwambiri. Pansi pa -147 °C, nayitrogeni imatha kusungunuka kukhala madzi pamene kupanikizika kukupitirira kupsinjika kwake kwa nthunzi.

Mu kupsinjika kwanthawi zonse kwa mafakitale, nayitrogeni imalowa mu compressor pa kutentha kozungulira (nthawi zambiri 20–40 °C) ndipo imatulutsidwa pa kutentha kokwera (nthawi zambiri 100–150 °C). Munthawi yonseyi, kutentha kwa mpweya nthawi zonse kumakhala pamwamba pa -147 °C. Chifukwa chake, pansi pa magwiridwe antchito abwinobwino, palibe chiopsezo choti nayitrogeni isungunuke mkati mwa compressor, mosasamala kanthu kuti kuthamanga kwake kukukwera bwanji.

Ndiye n’chifukwa chiyani mukufunsa funsoli?

Nkhawa nthawi zambiri imabwera chifukwa cha zochitika ziwiri:

1. Kuzizira kumayamba kapena kutentha kochepa kwambiri: Ngati compressor ili pamalo ozizira kwambiri (monga nyengo ya Arctic) ndipo gwero la nayitrogeni nalonso ndi lozizira kwambiri, mpweyawo ukhoza kulowa mu compressor kutentha komwe kumayandikira -50 °C kapena kutsika. Ngakhale kuti ukadali pamwamba pa -147 °C, mainjiniya ena akuda nkhawa ndi zotsatira za kuzizira komwe kumachitika m'deralo.
2. Kuziziritsa kwa Kukulitsa: Mpweya wopanikizika ukafalikira kudzera mu valavu kapena mtsinje (monga, panthawi ya kupsinjika, kutentha kwake kumatsika kwambiri (Joule-Thomson effect). Ngati nayitrogeni wopanikizika kwambiri wawonjezeka mwadzidzidzi kufika pa kupsinjika kochepa, kutentha kumatha kutsika pansi pa -147 °C, zomwe zimapangitsa kuti madzi asungunuke. Izi sizichitika.mkatichipinda chopondereza cha compressor koma chingachitike pansi pa mtsinje, mwachitsanzo, pamalo ochepetsera kupanikizika kapena njira yodzidzimutsa.

Mkati mwa nitrogen compressor yopangidwa bwino—palibe chiopsezo

Pa chipangizo choyezera nayitrogeni chomwe chimagwira ntchito mkati mwa kapangidwe kake, kutentha kwa mpweya sikufika pamlingo wofunikira. Kutentha kwa kutulutsa madzi nthawi zambiri kumakhala pakati pa 120 °C ndi 150 °C kuti chitetezeke komanso chikhale ndi moyo wopatsa mafuta (pa mitundu yoyezera mafuta). Ngakhale pakakhala kupanikizika mpaka 350 bar kapena kupitirira apo, nayitrogeni imakhalabe madzi kapena mpweya wofunikira kwambiri, osati madzi. Chifukwa chake, kuwonongeka kwa makina chifukwa cha kukhudzidwa ndi madzi (hydraulic lock) kapena kuzizira kwamkati si vuto pa ntchito yanthawi zonse ya nayitrogeni.

Kodi ndi liti pamene kusungunuka kwa madzi kungakhale vuto? Ndipo tingapewe bwanji?

Ngakhale kuti kusungunuka kwa madzi mkati mwa compressor si chiopsezo chenicheni, pali zochitika ziwiri zomwe nayitrogeni yamadzimadzi ingapangidwe mu makina a compressor, ndipo izi zimafuna kapangidwe kosamala:

1. Kuziziritsa pakati pa siteji ndi kutentha kochepa kwambiri kwa choziziritsira
Ngati compressor ili ndi ma intercooler omwe amagwiritsa ntchito refrigerant kapena madzi ozizira kuti aziziritse mpweya pakati pa magawo, ndizotheka kuziziritsa nayitrogeni kwambiri. Ngati kutentha kwa mpweya pambuyo pa intercooler kutsika pansi pa mame a chinyezi chilichonse (ngati chilipo), kuzizira kwa madzi ndi chiopsezo. Koma pa nayitrogeni yoyera, youma, intercooler iyenera kuziziritsa mpweyawo pansi pa -147°C kuti ipangitse kuti madzi azizire—zomwe sizichitika m'mafakitale.

• Pewani: Gwiritsani ntchito mpweya wozungulira kapena madzi ozizira bwino (osati madzi ozizira) kuti muziziritse. Ikani kuchuluka kwa mpweya wozizira kuti mpweya wotuluka ukhale wotentha kwambiri kuposa 0 °C (kapena kupitirira -147 °C, zomwe zimachitika zokha).

2. Kukula kwa mphamvu yamagetsi pansi pa mtsinje
Ngati nayitrogeni wopanikizika wasungidwa pa mphamvu yayikulu kenako nkukulitsidwa mpaka mphamvu yotsika kwambiri kudzera mu valavu (mwachitsanzo, mu malo odzaza mafuta a silinda ya gasi kapena potsetsereka), kutsika kwa kutentha kungayambitse kuzizira kwa chinyezi kapena kusungunuka kwa nayitrogeni ngati kutsika kwa mphamvu kuli kwakukulu ndipo kutentha koyambira kuli kochepa kwambiri.

• Kupewa: Yatsani nayitrogeni musanakulitse kapena gwiritsani ntchito magawo angapo okukulitsa ndi kutenthetsanso. Ikani cholekanitsa nthunzi ndi madzi pansi ngati pali chiopsezo choti madzi apitirire.

Chifukwa chiyani kusankha bwino kompresa ndi kapangidwe kake ndikofunikira

Dongosolo lopangidwa bwino la nitrogen compressor liyenera:

• Sungani kutentha kwa mpweya mosamala pamwamba pa malo ofunikira (komwe kumachitika zokha pamalo ozungulira).
• Gwiritsani ntchito kuziziritsa komwe sikuziziritsa mpweya kwambiri (monga, ma intercoolers a kukula koyenera okhala ndi kutentha koyenera).
• Phatikizani zotchingira zachitetezo zomwe zimatseka compressor ngati kutentha kwa mpweya kwatsika kwambiri (kosayembekezereka) kapena kwakwera kwambiri.
• Pa malo ozizira kwambiri, ganizirani zotenthetsera mpweya wolowera kapena zipinda zotenthetsera kuti kutentha kwa mpweya kukhale kokwera kuposa -20 °C.

Ubwino wa Xuzhou Huayan: Ma compressor a nayitrogeni opangidwa mwamakonda kuti azigwira ntchito modalirika komanso popanda kumwa madzi.

Kampani ya Xuzhou Huayan Gas Equipment Co., Ltd., takhala tikupanga ndi kupanga ma compressor a nayitrogeni kwa zaka zoposa 40. Mainjiniya athu akumvetsa kuti mpweya "wosavuta" monga nayitrogeni umafunikirabe uinjiniya woganiza bwino kuti tipewe mavuto osowa koma omwe angakhalepo monga kuzizira kwambiri, kuzizira kwa chinyezi, kapena kuchepetsa kuthamanga kwa mpweya molakwika.

• Kapangidwe ndi kupanga mkati mwa nyumba - Timawongolera chilichonse: kakonzedwe ka siteji, kukula kwa intercooler, kusankha zinthu, ndi zida zotetezera. Izi zimatsimikizira kuti compressor yanu ya nayitrogeni imagwira ntchito bwino malinga ndi momwe mulili komanso momwe zinthu zilili.
• Zokonzedwa kuti zigwirizane ndi ntchito yanu - Kaya mukufuna chipangizo chimodzi chopangira blanket yotsika mphamvu kapena compressor ya magawo anayi kuti ikwaniritse silinda yotsika mphamvu, timasintha kapangidwe kake kuti tipewe chiopsezo cha madzi oundana kapena kusungunuka kwa mpweya.
• Chidziwitso chotsimikizika—Ma compressor athu a nayitrogeni amagwiritsidwa ntchito m'mafakitale oyeretsera zinthu, m'mafakitale opanga mankhwala, m'mafakitale amagetsi, komanso m'mapakiti a chakudya padziko lonse lapansi—m'nyengo yozizira kwambiri ku Arctic mpaka kutentha kwa m'chipululu.
• Thandizo lonse - Timapereka malangizo omveka bwino okhudza kulamulira madzi ozizira, malo otenthetsera pakati pa masitepe, ndi njira zotetezera zokulitsa madzi m'mphepete mwa mtsinje.

Mapeto

Pa ntchito zonse za mafakitale, nayitrogeni simadziunjikira mkati mwa compressor ya nayitrogeni yopangidwa bwino chifukwa kutentha kwa mpweya nthawi zonse kumakhala pamwamba pa kutentha kwake kofunikira kwa -147 °C. Zoopsa zenizeni zimakhala pakukulitsa kapena kugwiritsa ntchito molakwika zinthu zoziziritsa kukhosi zomwe zimaphwanyidwa - zoopsa zomwe zingathetsedwe kudzera mu kapangidwe kabwino. Mwa kusankha compressor ya nayitrogeni yopangidwa bwino kuchokera kwa wopanga wodziwa bwino ntchito ndikutsatira njira zoyenera zogwirira ntchito, mutha kusangalala ndi kupsinjika kwa nayitrogeni kotetezeka, kodalirika, komanso kopanda madzi kwa zaka zambiri.

Ngati mukukonzekera njira yatsopano yochepetsera nayitrogeni kapena muli ndi nkhawa zokhudzana ndi zoopsa za kusungunuka kwa madzi mu dongosolo lanu lamakono, lankhulani ndi mainjiniya omwe akhala akuthetsa mavutowa kwa zaka zoposa 40.

Lumikizanani ndi gulu lathu la mainjiniya kuti mukambirane zomwe mukufuna pa compressor ya nayitrogeni.
