Umoya womoya kunyeyokugcina ebandayoumsebenzi wokugcina uxinzelelo kunye nezilumkiso.
I-rinkqubo yomkhenkceyinkqubo etywiniweyo. I-air-tightness system yefriji emva kokugcinwa kufuneka ihlolwe ngokungqongqo ukuqinisekisa umgangatho wokugcinwa, ukuphucula ukuthembeka kokusebenza, ukunciphisa ukulahlekelwa kwefriji, kunye nokuphucula uqoqosho lokusebenza. Ifriji ingena kakhulu. Ngoko ke, kuyimfuneko ukujonga ukunyanzeliswa komoya kwenkqubo yefriji.
Kufuneka kuqatshelwe ukuba igesi ye-nitrogen kufuneka isetyenziswe ukugcina uxinzelelo kwinkqubo yefriji. Ioksijini yigesi enokutsha. Ukuba ioksijini isetyenziselwa ukugcina uxinzelelo, inokubangela umlilo okanye ugqabhuko-dubulo!
- Ugcino loxinzelelo lomsebenzi wogcino oluncinci kunye oluphakathi olubandayo:
Kucetyiswa ukuba ucinezele amacala omabini erhasi kunye nolwelo ngaxeshanye. Okokuqala, qhagamshela i-gauge ye-pressure gauge kwi-channel ye-multi-purpose ye-valve yokuvala i-compressor ephezulu kunye nephantsi, kwaye ususe amacandelo akwinkqubo yokuqala engafanele ibe phantsi koxinzelelo olugqithiseleyo, njenge-valve yokulawula i-evaporation kunye nezinye izinto.
Ukuthatha i-R22 yefriji njengomzekelo, xa uxinzelelo oluphantsi loxinzelelo luyi-1.2MPa, ukutshaja kwenitrogen kuyekile. Emva kokuba uvavanyo lwecandelo loxinzelelo oluphantsi lugqityiwe, uvavanyo loxinzelelo lwenkqubo yoxinzelelo oluphezulu lwenziwa. Emva koxinzelelo lwenkqubo yoxinzelelo oluphezulu lonyuswe ukuya kwi-2.5MPa, ukutshaja kwenitrogen kuyekile. Gcina uxinzelelo lwe-24 ~ 48h.
| Inkqubo yefriji | I-R134a | I-R22 | R401A, R402A,R404A,R407A,R407B,R407C,R507 |
| Inkqubo yokucinezela okuphantsi | 1.2 | 1.2 | 1.2 |
| Inkqubo yobushushu obuphezulu | 2.0 | 2.5 | 3.0 |
Ukulumkela:
Kwiiyure ze-4 zokuqala zenkqubo, i-gauge ye-gauge yokuhla koxinzelelo ayidluli i-0.03MPa, kwaye emva koko iyaqhubeka izinzile (ngexesha lenkqubo yokuvavanya, ukuhla koxinzelelo ngenxa yokutshintsha kweqondo lokushisa ngokuqhelekileyo akudluli kuxinzelelo lwe-gauge ye-0.01 ~ 0.03MPa), kunye nenkqubo yefriji inokuthi ithathelwe ingqalelo ukuba ifanelekele uvavanyo lokuvuza.
2. Uxinzelelo lwenkqubo ye-multi-line system yokugcina ukusebenza
I-multi-connector kufuneka igxininiswe kumacala omabini ombhobho wegesi kunye nombhobho wolwelo ngexesha elifanayo, kuba uxinzelelo kumacala omabini egesi kunye nolwelo lunokukhusela iindawo zevalve ezifana ne-valve yokwandisa i-electronic kwiyunithi yeyunithi yangaphakathi yenkqubo ye-multi-connector ukuba yonakaliswe. Initrogen eyomileyo kufuneka isetyenziswe kuvavanyo lokuqina komoya. yenza i medium.
Ngethuba lovavanyo lobunzima bomoya, akuvumelekanga ukudibanisa uvavanyo lombhobho womatshini wangaphandle. Uxinzelelo lovavanyo lwenkqubo ye-R410A yi-4.0MPa, uvavanyo lokuqina komoya kufuneka lusebenzise initrogen njengomthombo, kwaye initrogen kufuneka yome. Cinizela kancinci, ngamanyathelo amathathu:
| Cinezela | Ixesha | Umsebenzi |
| 0.3MPa | >5 imiz | Ukuvuza okukhulu kunokufunyanwa |
| 1.5MPa | >5 imiz | Ukuvuza okukhulu kunokufunyanwa |
| 4.0MPa | 24h | Incinci ukuvuza kunokufunyanwa |
1. Uxinzelelo kwi-0.3MPa, hlala imizuzu emi-5 yokuhlolwa kokuvuza, kwaye unokufumana ukuvuza okukhulu;
2. Cinizela kwi-1.5MPa, hlala imizuzu emi-5 yokuhlolwa kokuqina komoya, kwaye ufumane ukuvuza okuncinci;
3. Gxininisa ukuya kwi-4.0MPa, hlala imizuzu emi-5 yovavanyo lwamandla, kwaye amadyungudyungu amahle angafunyanwa.
Emva koxinzelelo kuxinzelelo lovavanyo, gcina uxinzelelo lweeyure ezingama-24, kwaye uqaphele ukuba uxinzelelo luyehla. Ukuba uxinzelelo alwehli, lufanelekile.
I-R410A uluhlu lwegeyiji yoxinzelelo lwenkqubo yovavanyo kufuneka lube ngaphezulu kwe-4.5MPa
Ukulumkela:
Ukulungiswa koxinzelelo: Xa ubushushu buguquka nge-1 ° C, uxinzelelo lutshintsha ngokuhambelana ne-0.01MPa. Ukuba uxinzelelo lufuna ukugcinwa ixesha elide, uxinzelelo kufuneka luncitshiswe lube ngu-0.5MPa okanye ngaphantsi. Uxinzelelo oluphezulu lwexesha elide lunokukhokelela ekuvuzeni kwamalungu e-welding, kwaye kukho iingozi ezinokubakho zokhuseleko;
Uxinzelelo emva kokubamba uxinzelelo luchaphazeleka bubushushu be-ambient. Njengoko iqondo lokushisa liphakama, uxinzelelo luya kunyuka, kwaye njengoko ukushisa kwehla, ukushisa kuya kuhla. Ukuba ubushushu be-ambient yi-10 ° C xa uxinzelelo lugcinwe izolo, kwaye iqondo lokushisa liye lanyuka ngokukhawuleza ukuya kwi-25 ° C namhlanje, ngoko Ukuba iqondo lokushisa liyi-15 ° C, i-gauge yoxinzelelo iya kuhla, kwaye iyinto eqhelekileyo ukuba uxinzelelo lwe-gauge lube yi-38.4kgf / cm².
Aemva kokuba uvavanyo loxinzelelo lwe-nitrogen lufanelekile, i-vacuum yomise inkqubo. Qhagamshela igeyiji yokufunxa kwaye uqhube impompo yokufunxa ngaphezulu kweeyure ezi-2. Ukuba ayikwazi ukufikelela -755mmHg, qhubeka umpompa iyure enye. Emva kokufikelela ku-755mmHg, inokubekwa iyure enye, kwaye ifanelekile ukuba i-vacuum gauge ayiphakami.
