Njira yothetsera vuto la chodabwitsa kuti madzi a kompresa amagunda silinda mu chilonda cha mafakitale dongosolo

1. Zomwe zimayambitsa kunyowa sitiroko

① Mukamagwiritsa ntchito chiwongolero chamanja, valavu ya throttle imasinthidwa molakwika, kutsegulira kumakhala kwakukulu, kapena valavu yoyandama siyimatsekedwa mwamphamvu;

②Vavu yokulitsa matenthedwe imalephera, kapena babu yozindikira kutentha imayikidwa molakwika, ndipo kukhudzana kwake sikowona, zomwe zimapangitsa kutsegula kwambiri;

③Koyilo ya evaporator ndi yokhuthala kwambiri ndipo katundu wake ndi wocheperako;

④ Kuchuluka kwamafuta m’dongosolo;

⑤Kuzizira kwa kompresa ndikokulirapo, kapena kutentha kwa nyumba yosungiramo zinthu kumakhala kochepa;

⑥ Kusintha kolakwika kwa ntchito ya valve;

⑦ The refrigerant mu firiji dongosolo wodzazidwa ndi refrigerant kwambiri;

⑧Vavu yotulutsa solenoid yamadzimadzi samatsekedwa mwamphamvu;

⑨Mu magawo awiri ophikira firiji, pomwe valavu yoyamwa yapanthawi yotsika imatsekedwa kapena kutsegulidwa mwadzidzidzi (kapena kuchuluka kwa magawo ogwirira ntchito kumachepa ndikuwonjezeka), komanso mu intercooler. Koyilo ya serpentine mwadzidzidzi imalowa mumadzimadzi, yomwe imatha kuyambitsa kukwapula konyowa kwa compressor yapamwamba kwambiri.

Mwachidule, pali zinthu zambiri zomwe zimayambitsa kukwapula konyowa kwa compressor, ndipo zifukwa ziyenera kupezeka ndikuchotsedwa malinga ndi momwe zilili.

2. Zida, zida ndi zida zomwe zimagwiritsidwa ntchito kuti zizindikire kulephera kwa kunyowa kwa kompresa ya firiji.

① Chida: kuthamanga, multimeter, clamp mita, thermometer, double qi mita.

②Zida: ma wrenches, zida zokulitsira zitoliro, mavavu odzaza, zowongoka zowongoka, pliers, tochi, zida zapadera.

③Zida: botolo lamadzimadzi logwira ntchito, botolo la nayitrogeni, pampu ya vacuum, seti yonse ya kuwotcherera kwa gasi.

3. Ambiri ntchito njira kudziwa chonyowa sitiroko kulephera kompresa firiji

Popeza firiji dongosolo la mafakitale chillers ndi dongosolo zovuta wopangidwa ndi condensers, evaporators, mavavu kutambasuka, ndi zipangizo zambiri Chalk kuti n’zogwirizana ndi kulimbikitsana wina ndi mzake, kamodzi chipangizo firiji kulephera, munthu sayenera kungoganizira ena Pa mlingo wamba, m’pofunika kuchita kuyendera mwatsatanetsatane ndi kusanthula mwatsatanetsatane dongosolo lonse. Mwachidule, njira yodziwira ndiyo:

“Kumvera kumodzi, kukhudza kuwiri, kuyang’ana katatu, kusanthula zinayi” njira zoyambira.

Kuyang’ana kumodzi: yang’anani kuthamanga kwa kuyamwa ndi kutulutsa kuthamanga kwa kompresa; yang’anani kutentha kwa chipinda chozizira; yang’anani kuzizira kwa evaporator; yang’anani mkhalidwe wachisanu wa valavu yowonjezera kutentha.

Kumvetsera kwachiwiri: kumvetsera phokoso la compressor ikuyenda, payenera kukhala kayendedwe komveka bwino kwa valve. Pakamveka phokoso la “kupyola”, ndiko kumveka kwa nyundo yamadzi; mverani phokoso la refrigerant lomwe likuyenda mu valve yowonjezera; mverani phokoso la fan yoziziritsa; mverani phokoso la valve solenoid; mverani ngati pali kugwedezeka koonekeratu paipi.

Kukhudza katatu: kukhudza kutentha kwa kutsogolo ndi kumbuyo kwa compressor; kukhudza kutentha kwa kompresa silinda liner ndi yamphamvu mutu; kukhudza kutentha kwa kuyamwa ndi utsi mapaipi. Kusanthula zinayi: Gwiritsani ntchito malingaliro oyenerera a chipangizo cha firiji kuti mufufuze ndi kuweruza zochitikazo, kupeza chifukwa cha kulephera, ndikuchichotsa mwachindunji. Chigamulo cha kulephera kwa nyundo yamadzimadzi sichimangotengera chisanu cha chitoliro choyamwa, koma makamaka kuchokera kudontho lakuthwa mu kutentha kwautsi. Panthawiyi, kuthamanga kwa mpweya sikungasinthe kwambiri, koma silinda, crankcase, ndi chipinda chotulutsa mpweya zonse zimakhudzidwa. Kuzizira kapena chisanu. Pankhani ya hydraulic shock, imatha kuwononga makina opangira mafuta, kukulitsa ntchito ya mpope wamafuta, kufooketsa khoma la silinda, ndikuboola mutu wa silinda pazovuta kwambiri.

4. Njira yothetsera mavuto ndi kubwezeretsa ntchito yachibadwa ya firiji kompresa wonyowa sitiroko cholakwika

Kuthana ndi ngozi zowopsa zamadzimadzi ziyenera kuchitika mwachangu, ndipo pazovuta kwambiri, kuyendetsa galimoto mwadzidzidzi kuyenera kuchitidwa. Pamene sitiroko yonyowa pang’ono imachitika mu kompresa ya gawo limodzi, valavu yoyamwitsa yokhayo iyenera kutsekedwa, valavu yamadzimadzi ya evaporation iyenera kutsekedwa, kapena madzi omwe ali mumtsuko ayenera kuchepetsedwa. chakudya. Ndipo samalani ndi kuthamanga kwa mafuta ndi kutentha kwa mpweya. Kutentha kukakwera mpaka 50 ℃, yesani kutsegula valavu yoyamwa. Ngati kutentha kwa mpweya kukupitirirabe, mukhoza kupitiriza kutsegula, ndipo ngati kutentha kutsika, kutsekanso.

Kwa “stroko yonyowa” ya compressor ya magawo awiri, njira yochiritsira yochepetsetsa yonyowa yonyowa imakhala yofanana ndi ya siteji imodzi yokha. Koma pakakhala kuchuluka kwa ammonia kuthamangira mu silinda, kompresa yothamanga kwambiri imatha kugwiritsidwa ntchito kufooketsa ndikutuluka kudzera mu intercooler. Asanayambe kupopera pansi, madzi mu intercooler ayenera kutsanulidwa mu chidebe chokhetsa, ndiyeno kupanikizika kuyenera kuchepetsedwa. Jekete lamadzi lozizira la silinda ndi mafuta ayenera kukhazikika musanayambe kuchepetsa kupanikizika: kukhetsa madzi ozizira mu chipangizo kapena kutsegula valavu yaikulu yamadzi.

Pamene mlingo wamadzimadzi wa intercooler uli wochuluka kwambiri, compressor yapamwamba imawonetsa “stroko yonyowa”. Njira yochizira iyenera kuyamba kuzimitsa valavu yoyamwa ya kompresa otsika, ndiyeno zimitsani valavu yoyamwa ya compressor yapamwamba kwambiri ndi valavu yamadzimadzi ya intercooler. Ngati ndi kotheka, chotsani ammonia madzi mu intercooler mu ng’oma kumaliseche. Ngati kompresa yothamanga kwambiri yazizira kwambiri, siyani kuponderezana kocheperako. Njira yochiritsira yotsatira ndiyofanana ndi ya gawo limodzi.
