Kukonza Pamalo Ogulitsira

Kuyang'anira A. I. Kukonza Zinthu Zisanachitike

1. Kuyang'ana Malo Ogwirira Ntchito

a) Palibe kutayikira kwa madzi mufiriji komwe kumaloledwa m'chipindamo musanagwiritse ntchito.

b) Mpweya wopumira uyenera kusungidwa nthawi zonse panthawi yokonza.

c) Malawi otseguka kapena magwero otentha kwambiri opitilira 370°C (omwe angayatse malawi) ndi oletsedwa m'malo okonzera.

d) Panthawi yokonza: Ogwira ntchito onse ayenera kuzimitsa mafoni am'manja. Zipangizo zamagetsi zomwe zimayatsa magetsi ziyenera kuzimitsidwa.

Kugwira ntchito kwa munthu mmodzi, gulu limodzi, ndi dera limodzi n'kofunikira kwambiri.

e) Ufa wouma kapena chozimitsira moto cha CO2 (chomwe chikugwira ntchito bwino) chiyenera kupezeka pamalo okonzera.

1. Kuyang'anira Zipangizo Zokonzera

a) Onetsetsani kuti zipangizo zokonzera zikugwirizana ndi firiji ya makina otenthetsera. Gwiritsani ntchito zida zaukadaulo zokha zomwe zalangizidwa ndi wopanga makina otenthetsera.

b) Yang'anani ngati zipangizo zozindikirira kutayikira kwa firiji zakonzedwa. Kuchuluka kwa alamu sikuyenera kupitirira 25% ya LFL (Lower Fireability Limit). Zipangizozo ziyenera kugwira ntchito nthawi yonse yokonza.

1. Kuyang'anira Pampu Yotenthetsera ya R290

a) Onetsetsani kuti chotenthetsera chakhazikika bwino. Onetsetsani kuti nthaka yakhazikika bwino komanso kuti yakhazikika bwino musanachigwiritse ntchito.

b) Onetsetsani kuti magetsi a pampu yotenthetsera atsekedwa. Musanakonze, chotsani magetsi ndikutulutsa ma capacitor onse a electrolytic mkati mwa chipangizocho. Ngati mphamvu yamagetsi ikufunika kwambiri panthawi yokonza, kuyang'anira kutayikira kwa madzi mufiriji kuyenera kuchitika pamalo omwe ali pachiwopsezo chachikulu kuti mupewe ngozi zomwe zingachitike.

c) Yang'anani momwe zilembo zonse ndi zizindikiro zilili. Sinthani zilembo zilizonse zochenjeza zomwe zawonongeka, zosweka, kapena zosawerengeka.

B. Kuzindikira Kutayikira kwa Madzi Musanayambe - Kukonza Malo Otayira Madzi

1. Pamene pampu yotenthetsera ikugwira ntchito, gwiritsani ntchito chowunikira kutuluka kwa madzi kapena chowunikira kuchuluka kwa madzi (mtundu wa pampu - mtundu wokoka madzi) chomwe wopanga pampu yotenthetsera amalangiza (onetsetsani kuti mphamvu yake ikukwaniritsa zofunikira ndipo yasinthidwa, ndi kuchuluka kwa madzi owunikira kutuluka kwa madzi kwa 1 g/chaka ndi kuchuluka kwa alamu yowunikira kuchuluka kosapitirira 25% ya LEL) kuti muwone ngati mpweya ukutuluka. Chenjezo: Madzi ozindikira kutuluka kwa madzi ndi oyenera ma refrigerant ambiri, koma musagwiritse ntchito zosungunulira zokhala ndi chlorine kuti mupewe dzimbiri la mapaipi amkuwa chifukwa cha momwe chlorine ndi refrigerant zimachitikira.
2. Ngati mukukayikira kuti pali kutayikira, chotsani zinthu zonse zomwe zimawoneka zomwe zimayambitsa moto pamalopo kapena zimitsani motowo. Komanso, onetsetsani kuti malowo ali ndi mpweya wabwino.
3. Zolakwika zomwe zimafuna kuwotcherera mapaipi amkati a refrigerant.
4. Zolakwika zomwe zimafunika kusokoneza makina oziziritsira kuti akonze.

C. Zochitika Pamene Kukonza Kuyenera Kuchitikira ku Malo Othandizira

1. Zolakwika zomwe zimafuna kuwotcherera mapaipi amkati a refrigerant.
2. Zolakwika zomwe zimafunika kusokoneza makina oziziritsira kuti akonze.

D. Njira Zokonzera

1. Konzani zida zofunika.
2. Tsukani madzi mufiriji.
3. Yang'anani kuchuluka kwa R290 ndikutulutsa makinawo.
4. Chotsani ziwalo zakale zomwe zawonongeka.
5. Tsukani makina osungiramo zinthu mufiriji.
6. Yang'anani kuchuluka kwa R290 ndikuyikanso magawo atsopano.
7. Tulukani ndipo perekani ndalama mufiriji ya R290.

E. Mfundo Zachitetezo Panthawi Yokonza Malo

1. Posamalira chinthucho, malowo ayenera kukhala ndi mpweya wokwanira. N'koletsedwa kutseka zitseko ndi mawindo onse.
2. Malawi otseguka ndi oletsedwa kwambiri panthawi yokonza zinthu, kuphatikizapo kuwotcherera ndi kusuta. Kugwiritsa ntchito mafoni a m'manja nakonso n'koletsedwa. Ogwiritsa ntchito ayenera kudziwitsidwa kuti asagwiritse ntchito malawi otseguka pophikira, ndi zina zotero.
3. Pa nthawi yokonza nthawi yachilimwe, pamene chinyezi chili pansi pa 40%, njira zopewera kusinthasintha ziyenera kutengedwa. Izi zikuphatikizapo kuvala zovala za thonje loyera, kugwiritsa ntchito zipangizo zopewera kusinthasintha, komanso kuvala magolovesi a thonje loyera m'manja onse awiri.
4. Ngati kutayikira kwa mpweya wotentha m'firiji kwapezeka panthawi yokonza, njira zopumira mpweya ziyenera kutengedwa nthawi yomweyo, ndipo komwe kunatayikirako kuyenera kutsekedwa.
5. Ngati kuwonongeka kwa chinthucho kukufuna kutsegula makina oziziritsira kuti akakonzedwe, chiyenera kunyamulidwa kubwerera ku malo okonzera kuti chigwiritsidwe ntchito. Kuwotcherera mapaipi oziziritsira ndi ntchito zina zofanana ndizoletsedwa pamalo a wogwiritsa ntchito.
6. Ngati pakufunika zida zina pokonza ndipo pakufunika ulendo wachiwiri, chotenthetsera chiyenera kubwezeretsedwa momwe chinalili poyamba.
7. Njira yonse yosamalira iyenera kuonetsetsa kuti makina oziziritsira ali pansi bwino.
8. Popereka chithandizo pamalopo ndi silinda ya refrigerant, kuchuluka kwa refrigerant yodzazidwa mu silinda sikuyenera kupitirira mtengo womwe watchulidwa. Silinda ikasungidwa mgalimoto kapena ikayikidwa pamalo oikira kapena kukonza, iyenera kuyikidwa bwino molunjika, kutali ndi magwero a kutentha, magwero a moto, magwero a ma radiation, ndi zida zamagetsi.
