Ungayithola Kanjani Futhi Uyithole Kanjani Indawo Eqondile Yokuvuza Ngaphakathi Kwesiqandisi Esivuzayo?

Ungayilungisa kanjani ipayipi elivuzayo lesiqandisi?

Ama-evaporator ala mafriji ngokuvamile enziwe ngezinto zepayipi ezingezona ezethusi, futhi isikhunta sizovela ngemva kwesikhathi eside sokusetshenziswa. Ngemva kokuhlola izingxenye zepayipi ezivuzayo, indlela evamile yokulungisa iwukufaka ezinye izingxenye zepayipi ezonakele esikhundleni sezintsha zekhoyili. Ngakho-ke ungayihlola kanjani indawo yokuvuza kwefriji esiqandisini ngaphambi kokuba umsebenzi wokulungisa izingxenye ezishintshayo uqale?

 Ungakwahlulela kanjani ukuvuza kwesiqandisi esiqandisini?

Uma isiqandisi esiqondile singapholi, ngemva kokuqala umshini imizuzu eminingi, thinta ipayipi elinomfutho ophezulu bese uzizwa ushisa; ngesikhathi esifanayo, ipayipi elinomfutho ophansi liseduze nokushisa kwegumbi (ngokuvamile kufanele libe cishe ku-0°C, kanye neqhwa elincane), okungabhekwa njengephutha lesiqandisi. Ukuvuza kwesiqandisi.

 Ungawuchaza kanjani ububanzi bokuvuza?

Ngokuvamile, ukuvuza kweziqandisi kuzokwenzeka kulezi zesekeli: i-evaporator eyinhloko, i-evaporator eyisizayo, ishubhu lokushisa lohlaka lomnyango, i-condenser eyakhelwe ngaphakathi nakwezinye izindawo.

 

 Ungawahlola kanjani amapayipi anomoya ocindezelwe?

 

Indlela engathembekile yokuhlola ukuvuza:

Onjiniyela bokulungisa abangenalwazi baxhuma ngqo i-pressure gauge nepayipi lenqubo ye-compressor, bangeze umoya owomile ku-0.68MPa, futhi bahlole ingcindezi yepayipi langaphandle lesiqandisi. Le ndlela ngezinye izikhathi ayisebenzi, ngoba i-compressor, i-condenser, i-evaporator nezinye izinto zokufaka amapayipi zixhunywe ndawonye, ​​amapayipi ayaxhumana, futhi umthamo wegesi mkhulu. Endaweni ethile epayipini, inani lesibonisi se-pointer ye-pressure gauge ngeke lehle ngesikhathi esifushane, ngisho nangezinsuku ezingaphezu kweshumi. Ngakho-ke, le ndlela ayithembekile ekutholeni ukuvuza.

 

Indlela yokuthola ethembekile:

1. Okokuqala hlola ukuthi ipayipi eliveziwe liyavuza yini; (ipayipi eliveziwe lingahlolwa ukuthi alivuzi yini ngamabhamuza ensipho)

2. Uma kungekho ukuvuza epayipini eliveziwe, sekuyisikhathi sokushisela ngesilinganiso sokucindezela ukuhlola isimo sepayipi langaphakathi.

3. Shibiliza igeyiji yokucindezela epayipini elinomfutho ophansi (Φ6mm, elibizwa nangokuthi ipayipi lokungenisa) kanye nepayipi elikhipha igesi elinomfutho ophezulu (Φ5mm) eduze kwe-compressor;

4. Sika i-capillary ebangeni elingama-5mm ukusuka kusihlungi, bese uxhuma imikhawulo ye-capillary esikiwe nge-solder;

5. Faka umoya owomile ovela epayipini lenqubo ye-compressor kungcindezi engu-0.68MPa, bese uvimba ipayipi lenqubo ukuze ugcine lo mfutho womoya wangaphakathi;

6. Linda izinga lokushisa lazo zonke izindawo zokushisela lilingane nezinga lokushisa elizungezile (cishe ihora eli-1), bese usebenzisa ipeni lokuphawula ukuma kwenaliti yegeji esembozweni sengilazi esibonakalayo segeji yokucindezela;

7. Qhubeka uqaphela izinsuku ezingu-2-3 (isimo siwukuthi izinga lokushisa elizungezile alishintshi kakhulu, ngaphandle kwalokho lizothinta inani lomfutho womoya ngaphakathi kwepayipi);

8. Ngesikhathi senqubo yokubuka, uma inani lesikhombisi senye yamageyiji okucindezela lehla, sicela uliphawule esembozweni esibonakalayo sedayeli elihambisanayo;

9. Ngemva kokuqhubeka nokubuka izinsuku ezingu-2-3, ingcindezi yehla kakhulu, okufakazela iqiniso lokuthi ipayipi elixhunywe ku-pressure gauge livuvukile.

 

Hlaziya ngokwehlukana ngokuya ngokuvuza kwe-condenser kanye nokuvuza kwe-evaporator:

 

a)   Uma inani lesilinganiso sokucindezela engxenyeni ye-evaporator lehla, kudingeka lihlolwe futhi ngezigaba.

Hlola isigaba se-evaporator ngesigaba:

Susa ipuleti langemuva, hlukanisa ama-evaporator angaphezulu nangaphansi, faka i-pressure gauge, bese uqhubeka nokwandisa ukuhlolwa komfutho womoya kuze kube yilapho ingxenye ethile yesigaba se-evaporator enezimbobo ilandelwa.

 

b)  Uma kungukwehla kwengcindezi kwengxenye ye-condenser, imbangela kufanele inqunywe ngokwesakhiwo sayo.

Uma kunjaloi-condenser enesakhiwo esifakwe ngemuva, imbangela engaba khona kakhulu ukubhoboka kwepayipi lamazolo ohlakeni lomnyango.

Uma kunjaloi-condenser eyakhelwe ngaphakathi, kuyadingeka ukuhlola ngokwengeziwe izinguquko zenani lengcindezi yendawo ezigabeni, bese ufaka igeyiji entsha yokucindezela epayipini ukuze uyifinyelele.
