Kodi mfundo yogwiritsira ntchito makina oundana ndi iti? Akuti aliyense sadziwa za vutoli. Nkhaniyi ifotokoza mfundo yogwirira ntchito ndi kayendedwe ka makina oundana mwatsatanetsatane ndi chithunzi cha schematic.

Ice maker ndi mtundu wa zida zamakina zamafiriji zomwe zimaziziritsa madzi kudzera mufiriji mufiriji kuti apange ayezi. Monga momwe tawonetsera pa Chithunzi 1, amagwiritsidwa ntchito kwambiri m'madzi, zakudya, mkaka, mankhwala, chemistry, kusunga masamba ndi mafakitale ena. Ndi chitukuko cha anthu komanso kusintha kosalekeza kwa kapangidwe ka anthu, makampani oundana akuchulukirachulukira, ndipo kufunikira kwa makina oundana kukukulirakulira.

Ⅰ. Chidule chachidule cha mfundo zogwirira ntchito

Mfundo ya refrigeration ya ice maker ikuwonetsedwa mu chithunzi chotsatirachi. Refrigerant imapanikizidwa ndi kompresa kuti ikhale yotentha kwambiri komanso mpweya wothamanga kwambiri, utakhazikika ndi condenser, kusungunuka mumadzi otentha komanso othamanga kwambiri, osunthidwa ndi throttling system, kenako amayenderera kupita ku evaporator ndikumasanduka nthunzi mu payipi yake. Refrigerant imatenga kutentha kwa malo ozungulira kuti ayimitse madzi, kenako imabwerera ku kompresa kudzera mu chitoliro chobwerera, kenako imapanikizidwa ndikutulutsidwa. Kuzungulira kumeneku kumapangitsa madzi kukhala ayezi mpaka madzi oundana afika pa makulidwe akutiakuti.

The refrigerant ndi wothinikizidwa mu mkulu-kutentha ndi mkulu-anzanu gasi mu kompresa ndi kutayidwa, ndiyeno mwachindunji amalowa evaporator kudzera mu chitoliro kutentha kotunga, kotero kuti kutentha kwa evaporator kuwuka, ndiyeno ayezi cubes kugwa ndi evaporator pansi ophatikizana zochita za refrigerant ndi madzi owonjezera. Mukamaliza kupanga ayezi kamodzi, pitirizani kubwereza mpaka madzi oundana a mufiriji atawunjikana kotheratu, ndipo kupanga ayezi kuyimitsidwa. Akatulutsa madzi oundanawo, wopanga ayeziyo amapitirizabe kuchita zimenezi.

1. Njira yopangira ayezi

Makinawo akayatsidwa, ikani kusinthana kwa ntchito mu "Ice Making 20" boma. Panthawiyi, chizindikiro cha kuwala chayatsidwa, ndipo mpope wamadzi ndi valavu ya solenoid imayendetsedwa kwa masekondi angapo (nthawi yeniyeni ikhoza kukhazikitsidwa) kukhetsa madzi otsala mu thanki yamadzi, motero kuonetsetsa kuti madzi omwe amagwiritsidwa ntchito popanga ayezi ndi atsopano komanso oyera. amazindikira ngati ayezi mufiriji ali odzaza Ngati ayezi sali odzaza, yambani kompresa, yambani kuzizira kwa condenser nthawi yomweyo, kutseka pampu yamadzi ndi kukhetsa valavu, ndipo tsegulani valavu yolowetsa madzi kuti mulowe m'malo opangira ayezi.

Panthawi yonse ya ayezi kupanga ndi deicing, kompresa nthawi zonse kuthamanga, valavu yotentha mpweya kutsekedwa pambuyo kompresa kuyambika kwa masekondi angapo, mpope madzi imayamba pambuyo kompresa precools ayezi chipinda (evaporator) kwa masekondi angapo, ndi valavu yolowera madzi imatsekedwa pamene chojambulira mlingo wa madzi umakhudza madzi mu lakuya kwa masekondi angapo (pamene kukhudza madzi mlingo wa madzi ndi chizindikiro, pamene chodziwikiratu kukhudza madzi mlingo. kuyatsa), kapena pambuyo pa mphindi zingapo zakumwa madzi mosalekeza. Pansi pa ntchito ya mpope wa madzi ndi cholekanitsa madzi, madzi amayenda mofanana mu chipinda chilichonse cha chipinda chozizira. Ndi mapangidwe a ayezi, madzi amatsika ndipo chizindikiro cha madzi chimatuluka. Panthawiyi, madzi adzawonjezeredwa kamodzi mpaka chowunikira chamadzi chidzakumana ndi madzi kwa masekondi angapo, kuti atsimikizire kuti pali madzi okwanira kupanga ayezi.

Popanga ayezi, bolodi loyang'anira zamagetsi lidzawona mosalekeza kutentha kwa condenser, ndipo kutentha kwake kukadutsa kutentha kwake, kumayamba kuzizira kwa condenser kuti achepetse kutentha kwake.

Ndikoyenera kutchula kuti condenser yozizira zimakupiza ndi kompresa ena makina ayezi amawongoleredwa ndi contactor yemweyo, ndi kuthamanga lophimba chikugwirizana mndandanda mu dera lalikulu la zimakupiza kuzirala condenser monga chiyambi-kuyimitsa kulamulira condensing zimakupiza. Kuthamanga kwa condensing kukakwera kuposa pafupifupi 1.7MPa, fan fan imayamba ndikuyima ikakhala yotsika kuposa 1.4Ma:.

2. Deicing process

Pamene chojambulira cha ayezi chikukhudzana ndi kutuluka kwa madzi (osati ayezi) kwa masekondi angapo, pampu yamadzi imagwira ntchito ndipo valavu ya solenoid yothira imatsegula kukhetsa madzi mu sinki (nthawi yokhetsa ikhoza kusankhidwa ndi kusintha kwa nthawi yothira pa gulu). Pambuyo pakukhetsa molingana ndi nthawi yoikika, valavu yamadzi yolowera m'madzi, valavu yamadzi yotulutsa madzi ndi pampu yamadzi imatsekedwa, ndipo sagwiranso ntchito panthawi yonseyi. Kumayambiriro kwa ngalande zamadzi, valavu ya gasi yotentha imatsegulidwa, ndipo mpweya wotentha wa refrigerant umalowa mu evaporator kuti utenthe madzi oundana pamwamba pa evaporator. Ma ice cubes amalowa m'chipinda chosungiramo madzi oundana m'zidutswa pansi pa mphamvu yokoka, ndipo bokosi la bokosi limatsegulidwa, kutsiriza ndondomeko ya deicing, ndiyeno kulowanso mu chikhalidwe chopanga ayezi.
