Zifukwa za kulephera kwamphamvu kwa screw chiller ndi izi

Kuthamanga kwa screw chiller compressor ndikokwera kwambiri, zomwe zimapangitsa kuti chitetezo champhamvu kwambiri chigwire ntchito. The Kuthamanga kwa compressor imasonyeza kupanikizika kwa condensing, mtengo wabwinobwino uyenera kukhala 1.4 ~ 1.6MPa, ndipo mtengo wachitetezo umayikidwa ku 2.0MPa. Ngati kupanikizika kuli kwakukulu kwa nthawi yaitali, kumapangitsa kuti compressor ikugwira ntchito panopa ikhale yaikulu kwambiri, galimotoyo imakhala yosavuta kuwotcha, ndipo n’zosavuta kuwononga valavu yotulutsa compressor. Zifukwa za kulephera kwakukulu kwamagetsi ndi izi:

(1) Kutentha kwamadzi ozizira ndikokwera kwambiri ndipo condensation zotsatira zake ndizochepa. Malo ogwirira ntchito amadzi ozizira omwe amafunidwa ndi screw chiller ndi 30 ~ 35 ℃. Kutentha kwakukulu kwa madzi ndi kutentha kosakwanira kungayambitse kupanikizika kwakukulu kwa condensing. Chodabwitsa ichi nthawi zambiri chimapezeka munyengo zotentha kwambiri. Chifukwa cha kutentha kwa madzi okwera kungakhale: kulephera kwa nsanja yozizirira, monga faniyo sichikutsegulidwa kapena ngakhale kutembenuzidwa, wogawira madzi satembenuka, amawonetseredwa ngati kutentha kwa madzi ozizira kumakhala kwakukulu kwambiri, ndipo kumatuluka mofulumira; kutentha kwakunja kumakhala kwakukulu, njira yamadzi ndi yochepa, komanso kuchuluka kwa madzi omwe angayendetsedwe Pachifukwa ichi, kutentha kwa madzi ozizira nthawi zambiri kumasungidwa pamlingo wapamwamba kwambiri, womwe ukhoza kuthetsedwa mwa kuwonjezera thanki yosungirako.

(2) Kuthamanga kwa madzi ozizira sikukwanira ndipo sikungathe kufika pamtunda wamadzi omwe adavotera. Ntchito yaikulu ndi yakuti kusiyana kwapakati pakati pa malo olowera ndi kutulutsa madzi a unit kumakhala kochepa (poyerekeza ndi kusiyana kwa kuthamanga kumayambiriro kwa dongosolo kumayikidwa), ndipo kusiyana kwa kutentha kumakhala kwakukulu. Chifukwa cha kusakwanira kwa madzi oyenda ndi kusowa kwa madzi mu dongosolo kapena kukhalapo kwa mpweya. Njira yothetsera vutoli ndikuyika valavu yotulutsa mpweya pamtunda wa payipi kuti muthe; fyuluta ya payipi yatsekedwa kapena kusankhako kuli bwino kwambiri, ndipo kutsekemera kwa madzi kumakhala kochepa. Muyenera kusankha fyuluta yoyenera ndikuyeretsa fyuluta nthawi zonse; mpope wamadzi ndi wochepa ndipo sagwirizana ndi dongosolo.

(3) Condenser yasokonezedwa kapena kutsekedwa. Madzi a condensate nthawi zambiri amakhala madzi apampopi. Ndikosavuta kuyeza kutentha kukakhala pamwamba pa 30 ℃. Chifukwa nsanja yozizirirayo ndi yotseguka, imawululidwa mwachindunji ndi mpweya. Fumbi ndi zinthu zakunja zimatha kulowa mosavuta m’madzi ozizira, zomwe zimapangitsa kuti condenser ikhale yonyansa komanso yotsekereza ndipo malo osinthira kutentha ndi ochepa. , Kuchita bwino kumakhala kochepa, komanso kumakhudzanso kayendedwe ka madzi. Kuchita kwake ndikuti kusiyana kwa kuthamanga ndi kusiyana kwa kutentha pakati pa madzi olowera ndi kutuluka kwa unit kumakhala kwakukulu, kutentha kwapamwamba ndi kutsika kwa condenser kumakhala kokwera kwambiri pamene condenser imakhudzidwa ndi dzanja, ndipo chitoliro chamkuwa cha condenser chimakhala chotentha. The screw chiller iyenera kutsukidwa m’mbuyo nthawi zonse, ndipo kuyeretsa ndi kuchotsa mankhwala kuyenera kuchitika ngati kuli kofunikira.

(4) Firiji yachulukitsidwa. Izi nthawi zambiri zimachitika pambuyo pokonza, ndipo zimawonetsedwa ngati kuyamwa kwakukulu ndi kutulutsa mpweya komanso kuthamanga kwamphamvu, komanso kuthamanga kwambiri kwa kompresa. Iyenera kutulutsa mpweya molingana ndi kuthamanga kwa kuyamwa ndi kutulutsa, kuthamanga kwapakati komanso kugwira ntchito kwapano pansi pamikhalidwe yomwe idavotera mpaka yabwinobwino.

(5) Mipweya yosasunthika monga mpweya ndi nitrogen imasakanizidwa mufiriji. Izi nthawi zambiri zimachitika pambuyo pokonza, ndipo vacuum siinathe. Itha kungotsanulidwa, kuchotsedwanso, ndikudzazidwanso ndi firiji.

(6) Ma alarm abodza obwera chifukwa cha kuvulala kwamagetsi. Chifukwa cholumikizira champhamvu chamagetsi chamagetsi chimakhala chonyowa, sichilumikizidwa bwino kapena kuwonongeka, bolodi lamagetsi lamagetsi limakhala lonyowa kapena lowonongeka, ndipo kulephera kwa kulumikizana kumayambitsa chenjezo labodza. Pazolakwa zabodza zamtunduwu, chizindikiro cha HP pa bolodi lamagetsi nthawi zambiri chimakhala chozimitsa kapena chowala pang’ono, cholumikizira chamagetsi champhamvu kwambiri chimakhala chosavomerezeka pamanja, kompyuta imawonetsa “HP RESET”, kapena kutha yokha, kuthamanga kwamagetsi kompresa ndi wabwinobwino, komanso kuyamwa ndi kutulutsa kutulutsa ndikwachilendo.
