Indlela yokusombulula ingxaki yesenzeko sokuba ulwelo lwecompressor lubethe isilinda kwi chiller zemizi-mveliso isixokelelwano

1. Iimbangela zokungaphumeleli kwe-stroke emanzi

① Xa usebenzisa ulawulo lwezandla, ivalve ye-throttle ayilungiswanga kakuhle, ukuvuleka kukhulu kakhulu, okanye ivalve yokudada ayivalwanga ngokuqinileyo;

②Ivalve yokwandiswa kwe-thermal ayisebenzi, okanye ibhalbhu evavanya ubushushu ifakwe ngokungachanekanga, kwaye unxibelelwano aluyonyani, okukhokelela ekuvulekeni ngokugqithisileyo;

③Ikhoyili ye-evaporator ingqindilili kakhulu kwaye umthwalo mncinane kakhulu;

④ Ukuqokelela ngokugqithiseleyo kweoli kwinkqubo;

⑤Umthamo wokupholisa wecompressor mkhulu kakhulu, okanye umthwalo wobushushu wendawo yokugcina impahla uncinci;

⑥ Ulungelelwaniso olungafanelekanga lomsebenzi wevalvu;

⑦Isikhenkcezisi kwisistim somqandisi sigcwaliswe ngesikhenkcezisi kakhulu;

⑧Ivalve ye-solenoid yolwelo ayivalwanga ngokuqinileyo;

⑨Kumjikelo we-refrigeration wamanqanaba amabini, xa ivalve yokufunxa yenqanaba loxinzelelo oluphantsi ivalwe okanye ivuliwe ngequbuliso (okanye inani leeyunithi zokusebenza liyancipha ngokukhawuleza kwaye linyuka), nakwi-intercooler. Ikhoyili yenyoka ngokukhawuleza ingena kulwelo, enokuthi ibangele ngokulula i-stroke emanzi ye-high-pressure stage compressor.

Ngamafutshane, kukho izinto ezininzi ezibangela i-stroke emanzi ye-compressor, kwaye izizathu kufuneka zifunyenwe kwaye zipheliswe ngokwemeko ethile.

2. Izixhobo, izixhobo kunye nezixhobo ezisetyenziselwa ukufumanisa ukusilela kwe-stroke emanzi yecompressor yefriji.

①Isixhobo: igeyiji yoxinzelelo, i-multimeter, i-clamp meter, i-thermometer, i-qi meter ephindwe kabini.

②Izixhobo: izitshixo, izixhobo zokwandiswa kwemibhobho, iivalve zokuzalisa, iipliers ezitsolo, iipliers, iitotshi, izixhobo ezikhethekileyo.

③Izixhobo: ibhotile yolwelo olusebenzayo, ibhotile yenitrogen, impompo yevacuum, iseti epheleleyo yegesi yokuwelda.

3. Indlela yokusebenza ngokubanzi ukufumanisa ukungaphumeleli kwe-stroke emanzi ye-compressor yefriji

Ekubeni inkqubo yefriji ye-industrial chillers yinkqubo enzima eyenziwe ngama-condensers, i-evaporators, i-valve yokwandisa, kunye nezincedisi ezininzi zezixhobo ezihambelanayo kunye neziphembelela omnye nomnye, xa isixhobo sefriji sihluleka, umntu akufanele agxininise kuphela kwizinto ezithile Kwinqanaba lendawo. kuyimfuneko ukwenza uhlolo olubanzi kunye nohlalutyo olubanzi lwenkqubo yonke. Ngamafutshane, indlela eqhelekileyo yokufumanisa yile:

“Omnye uphulaphule, ukuchukumisa ezimbini, ukujonga okuthathu, uhlalutyo olune” isethi yeendlela ezisisiseko.

Enye inkangeleko: jonga uxinzelelo lokufunxa kunye nokukhupha uxinzelelo lwe-compressor; jonga izinga lokupholisa legumbi lokupholisa; jonga imeko yeqabaka ye-evaporator; jonga imeko yeqabaka yevalve yokwandisa i-thermal.

Ukuphulaphula okwesibini: ukuphulaphula isandi se-compressor esebenzayo, kufuneka kubekho kuphela ukunyakaza okucacileyo kwevalve. Xa kukho isandi esithi “through-through”, sisandi sempembelelo yehamile yolwelo; mamela isandi sefriji equkuqelayo kwivalve yokwandisa; mamela isandi somoya opholileyo; mamela isandi sevalve ye-solenoid; mamela ukuba kukho ukungcangcazela okucacileyo kumbhobho.

Ukuchukumisa okuthathu: bamba iqondo lokushisa langaphambili kunye neebheringi zangasemva zecompressor; chukumisa ubushushu be-compressor cylinder liner kunye nentloko ye-cylinder; bamba iqondo lokushisa lokufunxa kunye nokukhupha imibhobho. Uhlalutyo olune: Sebenzisa iithiyori ezifanelekileyo zesixhobo sefriji ukuhlalutya kunye nokugweba into eyenzekayo, ufumane isizathu sokungaphumeleli, kwaye uyisuse ngendlela ejoliswe kuyo. Isigwebo sokungaphumeleli kwesando solwelo asisekelwanga kuphela kwi-frosting yombhobho wokufunxa, kodwa ngokuyintloko ukusuka ekuhlahleni okubukhali kwiqondo lokushisa lokukhupha. Ngeli xesha, uxinzelelo lwe-exhaust aluyi kutshintsha kakhulu, kodwa isilinda, i-crankcase, kunye negumbi lokukhupha zonke zichaphazelekayo. Kubanda okanye iqabaka. Kwimeko yokutshatyalaliswa kwe-hydraulic, inokonakalisa inkqubo yokuthambisa, yenza umsebenzi wempompo yeoli ibe mandundu, icuthe ngokukhawuleza udonga lwe-cylinder, kwaye igqobhoze intloko ye-cylinder kwiimeko ezinzima.

4. Indlela yokusombulula ingxaki kunye nokubuyisela ukusebenza okuqhelekileyo kwefriji ye-compressor emanzi ye-stroke fault

Ukujongana neengozi zokutshatyalaliswa kwamanzi kufuneka kwenziwe ngokukhawuleza, kwaye kwiimeko ezinzima, ukuphathwa kwesithuthi esiphuthumayo kufuneka kuqhutywe. Xa istrowuku emanzi encinci isenzeka kwicompressor yenqanaba elinye, kufuneka ivalwe kuphela ivalve yokufunxa icompressor, ivalve yonikezelo lolwelo lwenkqubo yokuphuphuma komphunga kufuneka ivalwe, okanye ulwelo olukwisikhongozeli luncitshiswe. Noodle. Kwaye ubeke ingqalelo kuxinzelelo lweoyile kunye nobushushu bokuphelisa. Xa iqondo lobushushu linyuka liye kuma 50℃, zama ukuvula ivalve yokufunxa. Ukuba iqondo lokushisa liqhubeka likhuphuka, unokuqhubeka nokulivula, kwaye ukuba ukushisa kwehla, vala kwakhona.

Kuba “i-stroke emanzi” ye-compressor yamanqanaba amabini, indlela yonyango ye-low-pressure stage emanzi ifana ne-compressor eyodwa. Kodwa xa kukho inani elikhulu le-ammonia elikhawulezayo kwi-cylinder, i-compressor ephezulu yoxinzelelo ingasetyenziselwa ukudakumba kunye nokukhupha nge-intercooler. Ngaphambi kokupompa phantsi, i-liquid kwi-intercooler kufuneka ikhutshwe kwibhakethi yokukhupha, kwaye ke uxinzelelo kufuneka luncitshiswe. I-cylinder yokupholisa ibhatyi yamanzi kunye neoli kufuneka ipholile ngaphambi kokunciphisa uxinzelelo: khupha amanzi okupholisa kwisixhobo okanye uvule i-valve enkulu yamanzi.

Xa inqanaba le-liquid ye-intercooler liphezulu kakhulu, i-compressor ephezulu ibonisa “i-stroke emanzi”. Indlela yonyango kufuneka iqale icime ivalve yokufunxa ye-cofall-pressure compressor, kwaye emva koko ucime ivalve yokufunxa ye-high-pressure compressor kunye nevalve yokubonelela ngolwelo ye-intercooler. Ukuba kuyimfuneko, khupha i-ammonia liquid kwi-intercooler kwi-drum yokukhupha. Ukuba i-compressor yoxinzelelo oluphezulu iqhwale kakhulu, yeka i-compressor ephantsi yoxinzelelo. Indlela yonyango elandelayo iyafana naleyo yenqanaba elinye.
