Izizathu zokuhluleka komfutho ophezulu we-screw chiller zimi kanje

Ingcindezi yokukhipha i-screw chiller compressor iphezulu kakhulu, okubangela ukuthi i-relay yokuvikela ingcindezi ephezulu isebenze. I ingcindezi yokukhipha i-compressor ibonisa ukucindezela kokujiya, inani elivamile kufanele libe ngu-1.4~1.6MPa, futhi inani lokuvikela limiswe ukuze libe ngu-2.0MPa. Uma ukucindezela kuphezulu kakhulu isikhathi eside, kuzokwenza ukuthi i-compressor yokusebenza yamanje ibe nkulu kakhulu, i-motor kulula ukuyishisa, futhi kulula ukubangela umonakalo ku-valve yokukhipha i-compressor. Izizathu zokuhluleka kwe-voltage ephezulu zimi kanje:

(1) Izinga lokushisa lamanzi okupholisa liphezulu kakhulu futhi umphumela wokujiya awulungile. Isimo sokusebenza esilinganiselwe samanzi okupholisa adingwa i-screw chiller ngu-30~35℃. Izinga lokushisa eliphezulu lamanzi kanye nokushisa okungekuhle kuzoholela ekucindezelekeni okuphezulu. Lesi simo sivame ukwenzeka ezinkathini zokushisa okuphezulu. Isizathu sokushisa kwamanzi okuphezulu singase sibe: ukuhluleka kombhoshongo wokupholisa, njengokuthi i-fan ingavulwa noma ihlehliswe, umsabalalisi wamanzi akaphenduki, ubonakaliswa njengoba izinga lokushisa lamanzi okupholisa liphezulu kakhulu, futhi likhuphuka ngokushesha; izinga lokushisa langaphandle liphezulu, indlela yamanzi ifushane, futhi inani lamanzi elingasakazwa Kulesi simo, izinga lokushisa lamanzi okupholisa ngokuvamile ligcinwa ezingeni eliphakeme kakhulu, elingaxazululwa ngokukhulisa ithangi lokugcina.

(2) Ukugeleza kwamanzi okupholisa akwanele futhi akukwazi ukufinyelela ukugeleza kwamanzi okulinganiselwe. Ukusebenza okuyinhloko ukuthi umehluko wengcindezi phakathi kwe-inlet kanye ne-outlet yamanzi yeyunithi iba mncane (uma kuqhathaniswa nomehluko wengcindezi ekuqaleni kwesistimu ifakwa ekusebenzeni), futhi umehluko wokushisa uba mkhulu. Isizathu sokugeleza kwamanzi okwanele ukuntuleka kwamanzi ohlelweni noma ukuba khona komoya. Isixazululo ukufaka i-valve yokukhipha umoya endaweni ephakeme yepayipi ukuze kukhishwe; isihlungi sepayipi sivinjiwe noma ukukhetha kuhle kakhulu, futhi ukungena kwamanzi kunomkhawulo. Kufanele ukhethe isihlungi esifanele futhi Hlanza isihlungi njalo; iphampu yamanzi incane futhi ayifani nohlelo.

(3) I-condenser ingcolile noma ivinjiwe. Amanzi e-condensate ngokuvamile angamanzi kampompi. Kulula ukukala uma izinga lokushisa lingaphezu kuka-30℃. Ngenxa yokuthi umbhoshongo wokupholisa uvulekile, uvezwa ngokuqondile emoyeni. Uthuli nezinto zangaphandle zingangena kalula ohlelweni lwamanzi okupholisa, okwenza i-condenser ibe ngcolile futhi ivimbele futhi indawo yokushintshanisa ukushisa incane. , Ukusebenza kahle kuphansi, futhi kuthinta nokugeleza kwamanzi. Ukusebenza ukuthi umehluko wengcindezi kanye nomehluko wezinga lokushisa phakathi kokungena nokuphuma kwamanzi weyunithi uba mkhulu, amazinga okushisa aphezulu naphansi we-condenser aphakeme kakhulu lapho i-condenser ithintwa ngesandla, futhi ipayipi lethusi lokuphuma kwe-condenser liyashisa. I-screw chiller kufanele iwashwe ngemuva njalo, futhi ukuhlanzwa kwamakhemikhali nokwehliswa kufanele kwenziwe uma kunesidingo.

(4) Isiqandisi sikhokhiswe ngokweqile. Lesi simo ngokuvamile senzeka ngemva kokulungiswa, futhi sibonakala njengokucindezela okuphezulu kanye ne-exhaust kanye nokucindezela kwebhalansi, kanye ne-compressor ephezulu yokusebenza yamanje. Kufanele ikhishwe ngokuhambisana nengcindezi yokuncela nokukhipha, ingcindezi yebhalansi kanye nokusebenza kwamandla ngaphansi kwezimo ezilinganiselwe kuze kube yilapho evamile.

(5) Amagesi angajikijeki njengomoya ne-nitrogen axutshwa esiqandisini. Lesi simo ngokuvamile sivela ngemva kokulungiswa, futhi i-vacuum ayiphelele. Ingakhanywa kuphela, iphinde ikhishwe, futhi iphinde igcwaliswe ngesiqandisi.

(6) Ama-alamu amanga abangelwa amaphutha kagesi. Ngenxa yokuthi i-relay yokuvikela i-high-voltage inomswakama, ayixhunywanga kahle noma yonakele, iyunithi yebhodi ye-electronic inomswakama noma yonakele, futhi ukwehluleka kokuxhumana kubangela i-alamu engamanga. Ngalolu hlobo lwephutha elingamanga, inkomba yephutha ye-HP ebhodini likagesi ivamise ukucisha noma ikhanye kancane, i-relay yokuvikela i-high-voltage ayivumelekile ukusethwa kabusha ngesandla, ikhompuyutha iveza “HP RESET”, noma inyamalale ngokuzenzakalelayo, ukusebenza kwamanje kwe I-compressor ijwayelekile, futhi ingcindezi yokumunca nokukhipha nayo ijwayelekile.
