Ma screw chiller amatha kugawidwa m'magulu awiri: ma screw chiller oziziritsidwa ndi mpweya ndi ma screw chiller oziziritsidwa ndi madzi malinga ndi njira zosiyanasiyana zochotsera kutentha. Ma screw chiller oziziritsidwa ndi madzi amagwiritsa ntchito njira yoyendetsera madzi ya tower yozizira kuti achotse kutentha, pomwe ma screw chiller oziziritsidwa ndi mpweya amagwiritsa ntchito mpweya wochepa kuti achotse kutentha. Panthawi yogwira ntchito ya chipangizochi, padzakhala zonyansa zina chifukwa cha ubwino wa madzi kapena mavuto a mpweya, kapena chifukwa mafuta oziziritsidwa ndi matope, zomwe zidzakhudza makina onse oziziritsira. Chitani kuyeretsa ndi kukonza.
Ndiye, kodi mungatsuke bwanji makina oziziritsira a screw chiller?
1. Kodi mungadziwe bwanji kuti makina oziziritsira a screw chiller ayenera kutsukidwa?
Choyamba, tiyenera kuona ngati mtundu wa mafuta a compressor refrigeration oil wa screw chiller umasintha kukhala bulauni? Ngati ndi choncho, zikutanthauza kuti mtundu wa mafuta ndi mitambo. Kachiwiri, onani ngati fungo layaka, ndikuwona mphamvu ya resistance ya motor winding mu compressor. Ngati mphamvu ya resistance pakati pa winding ndi shell ndi yabwinobwino, zikutanthauza kuti insulation ndi yabwino. Apo ayi, mafuta a refrigeration ayenera kusinthidwa ndipo makina oziziritsira ayenera kutsukidwa.
Apa, ndikufuna kukumbutsa aliyense: Mu makina a madzi a chitofu, zinyalala zimamatira kwambiri pakhoma la mkati mwa chitoliro. Ngati chipangizocho chikuyenda kwa nthawi yayitali ndipo pali zinyalala zambiri, fyuluta yowumitsira idzatsekedwa ndipo chipangizocho sichidzatha kuzizira. Chifukwa chake, tikukulimbikitsani kuyeretsa chotenthetsera kutentha miyezi isanu ndi umodzi iliyonse ndikuyeretsa makinawo chaka chilichonse.
2. Kodi muyenera kuchita chiyani musanayeretse makina oziziritsira?
Pa kuipitsidwa kwa mpweya mu payipi ya makina oziziritsira, chotsukira chingagwiritsidwe ntchito kuchiyeretsa. Musanayeretse, ndikofunikira kutulutsa firiji mu payipi yoziziritsira, kenako kuchotsa compressor, ndikutsanulira mafuta a firiji mu payipi yopangira. Pa ntchito yoyeretsa, choyamba chotsani compressor ndi fyuluta youma, kenako chotsani capillary (kapena valavu yowonjezera) kuchokera ku evaporator, lumikizani evaporator ku condenser ndi payipi yosapanikizika, kenako gwiritsani ntchito payipi ya A yolumikiza mwamphamvu zida zoyeretsera ndi mapaipi otulutsa ndi kutulutsa a compressor. Kenako yeretsani zida zomwe zimagwiritsidwa ntchito, monga mapampu, matanki, zosefera, zowumitsira, ndi ma valve osiyanasiyana.
Njira yoyeretsera ndi iyi: choyamba ikani chotsukira mu thanki yamadzimadzi, kenako yambani pampu, igwireni ntchito, ndikuyamba kuyeretsa. Mukatsuka, chitani ntchito zingapo kutsogolo ndi kumbuyo mpaka chotsukiracho chisawonetse acidity. Pa kuipitsidwa pang'ono, chimangofunika kuyenda kwa ola limodzi. Pa kuipitsidwa kwakukulu, zimatenga maola 3-4. Ngati chatsukidwa kwa nthawi yayitali, chotsukiracho chimakhala chodetsedwa, ndipo fyuluta nayonso yatsekeka komanso yakuda. Chotsukiracho ndi fyuluta ziyenera kusinthidwa musanachite izi. Dongosolo likatsukidwa, chotsukiracho chimakhala chodetsedwa ndipo fyuluta nayonso yatsekeka komanso yakuda. Chotsukiracho chomwe chili mu chosungira chamadzimadzi chiyenera kuchotsedwa mu chitoliro chamadzimadzi. Pambuyo poyeretsa, kupopera ndi kuumitsa kwa nayitrogeni kuyenera kuchitika pa payipi yoziziritsira, kenako kudzazidwa ndi fluorine, ndipo ntchito yokonza zolakwika za chipangizocho iyenera kuchitika kuti zitsimikizire kuti choziziritsiracho chikugwira ntchito bwino.
Mphamvu ya chotsukira cha screw ndi yayikulu, ndipo pali kusankha mutu umodzi kapena mutu wawiri. Chotsukira cha screw cha mutu umodzi chili ndi compressor imodzi yokha, yomwe ingasinthidwe m'magawo anayi kuyambira 100% mpaka 75% mpaka 50% mpaka 25%. Chotsukira cha screw cha mutu wawiri chimapangidwa ndi ma compressor awiri ndipo chili ndi machitidwe awiri odziyimira pawokha. Imodzi ikalephera kapena ikufunika kukonzedwa, inayo ingagwiritsidwe ntchito mwachizolowezi, zomwe ndizosavuta kugwiritsa ntchito.
