Momwe mungathetsere vuto la kutsekeka kwa makina oziziritsira ndi nkhawa ya ogwiritsa ntchito ambiri. Kutsekeka kwa makina oziziritsira kumachitika makamaka chifukwa cha kutsekeka kwa mafuta, kutsekeka kwa ayezi kapena kutsekeka kodetsedwa mu valavu yolumikizira, kapena kutsekeka kodetsedwa mu fyuluta yowumitsira. Lero ndikupatsani chiyambi chatsatanetsatane cha zomwe zimayambitsa ndi njira zothetsera kutsekeka kwa makina.
1. Kulephera kutsekeka kwa mafuta
Chifukwa chachikulu chomwe mafuta amatsekeka ndichakuti silinda ya compressor yawonongeka kwambiri kapena malo olumikizira silinda ndi akulu kwambiri. Mafuta omwe amatuluka mu compressor amatuluka mu condenser, kenako amalowa mu fyuluta yowumitsa pamodzi ndi refrigerant. Chifukwa cha kukhuthala kwakukulu kwa mafuta, amatsekedwa ndi desiccant mu fyuluta. Mafuta akakhala ambiri, amapanga kutsekeka pamalo olowera fyuluta, zomwe zimapangitsa kuti Refrigerant isayende bwino.
Mafuta ochulukirapo oziziritsa amakhalabe mu makina oziziritsa, zomwe zimakhudza momwe makina oziziritsira amagwirira ntchito kapena zimalepheretsa makina oziziritsa. Chifukwa chake, mafuta oziziritsa omwe ali mu makinawo ayenera kuchotsedwa.
Momwe mungathanirane ndi kutsekeka kwa mafuta: Pamene fyuluta yatsekeka, isintheni ndi yatsopano, ndipo gwiritsani ntchito nayitrogeni wothamanga kwambiri kuti mutulutse gawo la mafuta oziziritsa omwe asonkhanitsidwa mu condenser. Ndi bwino kugwiritsa ntchito chowumitsira tsitsi kuti mutenthe condenser mukayamba kugwiritsa ntchito nayitrogeni.
Mwa njira, netiweki yoziziritsira idzakamba za filimu yamafuta apa. Chifukwa chachikulu cha filimu yamafuta ndichakuti mafuta odzola omwe sanalekanitsidwe ndi cholekanitsa mafuta adzalowa mu dongosolo ndikuyenda ndi firiji yomwe ili mu chubu, ndikupanga kuzungulira kwamafuta. Pali kusiyana kwakukulu pakati pa filimu yamafuta ndi kutseka mafuta.
Kuopsa kwa filimu ya mafuta:
Ngati filimu ya mafuta imamatira pamwamba pa chosinthira kutentha, kutentha kwa condensation kudzakwera ndipo kutentha kwa nthunzi kudzatsika, zomwe zimapangitsa kuti mphamvu igwiritsidwe ntchito kwambiri;
Pamene filimu yamafuta ya 0.1mm yalumikizidwa pamwamba pa condenser, mphamvu yoziziritsira ya compressor yoziziritsira imachepa ndi 16% ndipo mphamvu yogwiritsira ntchito mphamvu imawonjezeka ndi 12.4%;
Pamene filimu ya mafuta mu evaporator ifika pa 0.1mm, kutentha kwa evaporation kudzatsika ndi 2.5°C ndipo mphamvu yogwiritsidwa ntchito idzawonjezeka ndi 11%.
Njira yochizira filimu ya mafuta:
Kugwiritsa ntchito mafuta ogwira ntchito bwino kwambiri kungachepetse kwambiri kuchuluka kwa mafuta omwe amalowa mu payipi ya system;
Ngati mafuta ali kale mu dongosololi, akhoza kutsukidwa ndi nayitrogeni kangapo mpaka mpweya wofanana ndi nthunzi utatha.
2. Kutseka kwa ayezikulephera
Kulephera kwa ayezi kutsekeka kumachitika makamaka chifukwa cha chinyezi chochuluka mu makina oziziritsira. Pamene makina oziziritsira akuzungulira mosalekeza, chinyezi mu makina oziziritsira chimakhazikika pang'onopang'ono pa malo otulukira valavu ya throttle. Popeza kutentha komwe kumatuluka valavu ya throttle kumakhala kotsika kwambiri, madzi amapangidwa. Madzi amaundana ndipo pang'onopang'ono amawonjezeka. Kufikira pamlingo winawake, chubu cha capillary chimatsekedwa kwathunthu ndipo makina oziziritsira satha kuyenda.
Magwero akuluakulu a chinyezi:
Chinyezi chotsala m'zigawo zosiyanasiyana ndi mapaipi olumikizira a makina oziziritsira chifukwa cha kuuma kosakwanira;
Mafuta a mufiriji ndi mufiriji ali ndi chinyezi choposa kuchuluka kololedwa;
Kulephera kutsuka mpweya woipa panthawi yoyika kapena kuyika molakwika kumabweretsa chinyezi;
Pepala loteteza kutentha la mota mu compressor lili ndi chinyezi.
Zizindikiro za kutsekeka kwa ayezi:
Mpweya umayenda pang'onopang'ono komanso pang'onopang'ono;
Pamene kutsekeka kwa mpweya kuli kwakukulu, phokoso la mpweya limatha, kuyenda kwa mpweya mufiriji kumasokonekera, ndipo condenser pang'onopang'ono imakhala yozizira;
Chifukwa cha kutsekeka, mphamvu ya utsi imawonjezeka ndipo phokoso la makina limawonjezeka;
Palibe firiji yomwe imalowa mu evaporator, malo oundana pang'onopang'ono amakhala ochepa, ndipo kuzizira kumakhala koipa kwambiri;
Pambuyo pa nthawi yotseka, firiji imayamba kubwezeretsedwanso (ma ice cubes ozizira amayamba kusungunuka)
Kutsekeka kwa ayezi kumapanga kubwerezabwereza kwa kuchotsedwa kwakanthawi, kutsekedwa kwakanthawi, kutsekedwa kenako kuchotsedwa, ndikuchotsedwanso ndikutsekedwa kachiwiri.
Chithandizo cha kutsekeka kwa ayezi:
Kutsekeka kwa ayezi kumachitika mu makina oziziritsira chifukwa chakuti pali chinyezi chochuluka mu makinawo, choncho makina onse oziziritsira ayenera kuumitsidwa. Njira zokonzera ndi izi:
Chotsani ndikusintha fyuluta yowumitsa. Pamene chizindikiro cha chinyezi mu galasi lowoneka la makina oziziritsira chikhala chobiriwira, chimaonedwa kuti ndi choyenera;
Ngati madzi ambiri alowa m'dongosolo, tsukani ndi nayitrogeni pang'onopang'ono, sinthani fyuluta, sinthani mafuta oziziritsira, sinthani firiji, ndikutsuka mpaka chizindikiro cha chinyezi chomwe chili mugalasi chitakhala chobiriwira.
3. Vuto loipa la kutsekeka
Makina oziziritsira akatsekedwa, firiji siimatha kuyendayenda, zomwe zimapangitsa kuti compressor iziyenda mosalekeza. Evaporator si yozizira, condenser si yotentha, chipolopolo cha compressor si chotentha, ndipo palibe phokoso la mpweya womwe ukuyenda mu evaporator. Ngati pali zinyalala zambiri mu dongosololi, choumitsira fyuluta chidzatsekedwa pang'onopang'ono ndipo chophimba cha fyuluta cha makina opopera chidzatsekedwa.
Zifukwa zazikulu zotsekeka kwa dothi:
Fumbi ndi zitsulo zochokera pa ntchito yomanga ndi kukhazikitsa, ndi oxide wosanjikiza pamwamba pa khoma lamkati womwe umagwa panthawi yolumikiza mapaipi;
Pa nthawi yokonza gawo lililonse, malo amkati ndi akunja sanatsukidwe, ndipo mapaipi sanatsekedwe bwino ndipo fumbi linalowa m'mapaipi;
Mafuta oziziritsira ndi firiji ali ndi zinthu zosafunika, ndipo ufa wa desiccant mu fyuluta yowumitsira ndi woipa;
Kuchita bwino pambuyo pa kutsekeka kwauve:
Ngati yatsekedwa pang'ono, evaporator idzamva kuzizira kapena kuzizira, koma sipadzakhala chisanu;
Mukakhudza pamwamba pa valavu yowumitsira ndi chotsukira cha fyuluta, idzamveka yozizira mukaikhudza, ndipo padzakhala chisanu, kapena ngakhale chisanu choyera;
Evaporator si yozizira, condenser si yotentha, ndipo chipolopolo cha compressor si chotentha.
Kuthana ndi mavuto otsekeka kwa dothi: Kutsekeka kwa dothi nthawi zambiri kumachitika mu fyuluta yowumitsira, fyuluta yolumikizira maukonde, fyuluta yolumikizira maukonde, ndi zina zotero. Fyuluta yolumikizira maukonde ndi fyuluta yolumikizira maukonde zimatha kuchotsedwa ndikutsukidwa, ndipo fyuluta yowumitsira nthawi zambiri imasinthidwa. Pambuyo poti yasinthidwa, makina oziziritsira amafunika kufufuzidwa ngati akutuluka madzi ndikutsukidwa ndi vacuum.

Ngati mtunda pakati pa chubu cha capillary ndi chophimba cha fyuluta mu choumitsira fyuluta uli pafupi kwambiri, izi zitha kuyambitsa kutsekeka kwauve.
