1.Ukuhlola izinto zogcino lwezikrufu ezicinezelayo
(1) Jonga ukuba ngaba kukho iimpawu zokunxiba ezingaqhelekanga kumphezulu ongaphakathi womzimba kunye nomphezulu wevalve yesilayidi, kwaye ulinganise ubungakanani kunye nokungqukuva komphezulu ongaphakathi ngegeyiji yokudayela engaphakathi.
(2) Jonga ukuba ngaba akhona na amanqaku okunxiba kwisiphelo sobuso be-rotors eziphambili kunye neziqhutywayo kunye nezitulo zokufunxa kunye ne-exhaust ekupheleni.
(3) Jonga ukunxiba kwe-diameter yangaphandle kunye nezinyo ezingundoqo kunye neerotors eziqhutywayo, kwaye ulinganise i-diameter yangaphandle ye-rotor kunye ne-dial dial gauge yangaphandle.
(4) Ukulinganisa ububanzi be-shaft ephambili ye-rotor kunye nobubanzi bangaphakathi bomngxuma oyintloko wokuthwala, kwaye ukhangele ukunxiba kweyona nto iphambili.
(5) Jonga ukunxitywa kwetywina leshaft.
(6) Jonga zonke iiringi zika-"o" kunye nemithombo ye-deformation kunye nomonakalo.
(7) Jonga imeko yazo zonke iisekethe zeoyile zangaphakathi zecompressor.
(8) Jonga ukuba isalathisi samandla sonakalisiwe okanye sivaliwe.
(9) Jonga ipiston yeoyile kunye nepiston yebhalansi yokunxiba okungaqhelekanga.
(10) Jonga ukuba undoqo wothumelo okanye i-diaphragm yodibaniso yonakele.
2.Ukugcinwa kunye nokungaphumeleli kwefriji ye-screw
A.I-alamu yokuhamba kwamanzi abandayo ephantsi
Ukutshintsha okujoliswe kuko kwamanzi abandayo akuvaliwe, khangela kwaye ulungelelanise ukutshintshwa kokuhamba.
Impompo yamanzi abandayo ayivulwanga.
Ivalve yokuvala yombhobho wamanzi abandayo ayivulekanga.
B.I-alamu yoxinzelelo lweoyile
Ukuphelelwa yi-oyile kunye ne-alam yokutshintsha inqanaba le-oyile, i-alam yoxinzelelo lweoyile, i-alam yoxinzelelo lweoyile.
Ukusebenza kwexesha elide phantsi kweemeko zomthwalo ophantsi, indlela engcono kakhulu kukugcina iyunithi isebenza kumthwalo opheleleyo.
Ubushushu bamanzi okupholisa buphantsi (ngaphantsi kwama-20 degrees), okwenza kube nzima ukugcina ukunikezelwa kweoli ngokuhlukana koxinzelelo.
C.I-alamu yoxinzelelo oluphantsi lokufunxa
Inzwa yoxinzelelo oluphantsi iyasilela okanye inonxibelelwano olubi, jonga okanye uyitshintshe.
Intlawulo yefriji engonelanga okanye ukuvuza kweyunithi, itshekhi kunye nentlawulo.
Isihluzi esivaliweyo somiso, siqhawule kwaye sicoceke.
Xa ukuvulwa kwevalve yokwandisa kuncinci kakhulu, i-motor steping yonakaliswe okanye inoqhagamshelwano olubi, khangela, ukulungisa okanye ukuyibuyisela.
D.I-alamu yokukhupha uxinzelelo oluphezulu
Ukuba amanzi okupholisa akavulwanga okanye ukuhamba kwawo akwanelanga, ukuhamba kungandiswa;
Iqondo lokushisa lokungena kwamanzi okupholisa liphezulu, khangela isiphumo senqaba yokupholisa;
Imibhobho yobhedu kwi-condenser ihlanjululwe kakhulu, kwaye imibhobho yobhedu kufuneka ihlambuluke;
Kukho igesi engacondensable kwiyunithi, ukukhupha okanye ukucoca iyunithi;
Isikhenkcezisi esigqithisileyo sinokufunyanwa kwixabiso elifunekayo lefriji;
I-plate partition in the condenser water room is half-through, ukulungisa okanye ukubuyisela i-gasket yegumbi lamanzi;
Inzwa yoxinzelelo oluphezulu iyasilela.Buyisela isixhobo soluvo.
E.Impazamo yoxinzelelo loxinzelelo lweoyile
I-economizer okanye inzwa yoxinzelelo lweoyile ayiphumelelanga, yijonge kwaye uyibuyisele endaweni yayo.
Izihluzi zangaphakathi nangaphandle zivaliwe, buyisela isihluzo.
Ukungaphumeleli kwevalvu ye-solenoid ye-oyile.Khangela ikhoyili, ivalve yesolenoid, ukulungisa okanye ukubuyisela.
Ipompo ye-oyile okanye ivalve yendlela enye yeqela lempompo yeoli inempazamo, jonga kwaye uyibuyisele.
F.Ukuqwalasela ukuba intlawulo yefriji ayonelanga
kufuna ingqalelo!Iglasi yokubona kumbhobho wolwelo ibonisa ukuba amaqamu anganelanga ukugweba ukungabikho kwefriji;ukushisa kwe-steam egcweleyo akwanele ukugweba ukungabikho kwefriji;inokugwetywa ngezi ndlela zilandelayo:
Qinisekisa ukuba iyunithi isebenza phantsi kweemeko zomthwalo we-100%;
Qinisekisa ukuba iqondo lokushisa lokuphuma kwamanzi abandayo kwi-evaporator liphakathi kwe-4.5 kunye ne-7.5 degrees;
Qinisekisa ukuba umehluko weqondo lokushisa phakathi kokungena kwamanzi abandayo kunye nokuphuma kwe-evaporator phakathi kwe-5 kunye ne-6 degrees;
Qinisekisa ukuba ubushushu bokutshintsha kobushushu kwi-evaporator buphakathi kwe-0.5 kunye ne-2 degrees;
Ukuba le miqathango ingentla ayihlangabezwanga, kwaye ukuvulwa kwevalve yokwandisa i-elektroniki kukhulu kune-60%, kwaye iglasi yokubona ibonisa amaqamza, eli nqaku livela kwi-Refrigeration Encyclopedia, esekelwe kuyo kunokugwetywa ukuba iyunithi ayinayo ifriji.Musa ukuhlawula ngaphezulu ngefriji, njengoko oku kuya kubangela uxinzelelo oluphezulu lokukhupha, ukusetyenziswa kwamanzi okupholisa ngakumbi, kwaye mhlawumbi umonakalo kwi-compressor.
G.Yongeza ifriji
Ukuze kuqinisekiswe ukuba ifriji eyaneleyo yongezwa, kuyimfuneko ukwenza iyunithi iqhube ngokuqhubekayo phantsi kweemeko zomthwalo we-100%, ukwenzela ukuba ubushushu bokukhutshwa kwamanzi abandayo kwi-evaporator yi-5 ~ 8 degrees, kunye nokwahlukana kweqondo lokushisa phakathi kwendawo yokungena. kwaye amanzi aphumayo aphakathi kwe-5 ~ 6 degrees.Indlela yokugweba inokubhekisa koku kulandelayo:
Ukuvulwa kwevalvu yokwandisa kuphakathi kwe-40% kunye ne-60%;
Umahluko wobushushu bokudlulisa ubushushu be-evaporator uphakathi kwe-0.5 kunye ne-2 degrees;
Qinisekisa ukuba iyunithi isebenza phantsi kweemeko zomthwalo we-100%;.
Yongeza ulwelo ngevalve yokuzalisa ulwelo kumphezulu we-evaporator okanye ivalve ye-engile ezantsi;
Emva kokuba iyunithi iqhube ngokuzinzileyo, jonga ukuvulwa kwevalve yokwandisa i-elektroniki;
Ukuba ukuvulwa kwevalve yokwandisa i-elektroniki yi-40 ~ 60%, kwaye kukho rhoqo amaqamza kwiglasi yokubona, yongeza ifriji yolwelo;
H,ukumpompa ifriji
kufuna ingqalelo!Musa ukusebenzisa icompressor ukumpompa ifriji kwi-evaporator, kuba xa uxinzelelo lokufunxa lungaphantsi kwe-1kg, lungonakalisa i-compressor.Sebenzisa isixhobo sokumpompa isikhenkcisi ukumpompa isibandisi.
(1) Faka endaweni yesihluzo se-oyile eyakhelweyo
Xa iyunithi iqhuba iiyure ezingama-500 okokuqala, i-oyile yokucoca i-compressor kufuneka ihlolwe.Emva kweeyure zonke ze-2000 zokusebenza, eli nqaku livela kwi-Refrigeration Encyclopedia, okanye xa ukuhlukana koxinzelelo phakathi kwangaphambili nasemva kwe-oyile yokucoca kufunyenwe ukuba kudlule i-2.1bar, i-oyile yokucoca kufuneka idityaniswe kwaye ihlolwe.
(2) Xa ezi meko zimbini zilandelayo zisenzeka, ukuhla koxinzelelo lwe-oyile yokucoca kufuneka kujongwe:
Icompressor iyacima ngenxa ye-alarm 'yowona mahluko aphezulu woxinzelelo lwe-oyile kwisekethe yonikezelo lwe-oyile';
I-Compressor iyacima ngenxa ye-alam ethi 'Inqanaba le-oyile lokutshintsha liqhawulwe'.
J.Inkqubo yokutshintshwa kwe-oyile yokucoca
Cima, cima isitshixo somoya, vala ivalve yokulungisa isihluzo se-oyile, uqhagamshele ithumbu kumngxunya wokucoca ioyile, khupha ioyile kwisihluzo se-oyile, vula iplagi yokucoca ioyile, kwaye ukhuphe iplagi yesihluzo se-oyile. , i-'O' emanzi nge-oyile, faka isihluzo esitsha se-oyile, faka iplagi entsha, buyisela isihluzo se-oyile esincedisayo (isihluzo se-oyile sangaphandle), cima isihluzo se-oyile ngezibuko lenkonzo yokucoca kunye nokuncedisa umoya kwisihluzo se-oyile, vula inkonzo yokucoca ioyile. ivalve.
K,iqondo lokutshintsha kweoli liqhawulwe
Ukuba iyunithi ilumkisa ngokuphindaphindiweyo ngenxa yokuba ukutshintshwa kwezinga leoli kunqanyuliwe, kuthetha ukuba ioli kwi-oil separator ayanelanga kwaye inani elikhulu leoli likwi-evaporator.Ukuba utshintsho lwezinga leoli luhlala lunqanyuliwe, sebenzisa ipompo yeoli ukongeza iilitha ezingaphezu kweelitha zeoli kwi-oyile yokwahlula ioli, ungafaki ioli kuyo nayiphi na enye indawo, qinisekisa ukuba utshintsho lwezinga leoli luvaliwe, qalisa kwakhona iyunithi, kwaye uqhube. kwi-100% umthwalo ubuncinane kwi-1 iyure phantsi kweemeko eziqhelekileyo.
L.Ioli ebalekayo
Izizathu zokuqhuba ioli: iqondo eliphantsi lokukhupha i-superheat degree likhokelela kwisiphumo esibi sokwahlukana kwe-oyile, kwaye iqondo lokushisa elihluthayo leyunithi liphantsi kakhulu (ubushushu bamanzi okupholisa buphantsi), okukhokelela kumohluko ophantsi woxinzelelo lweoyile, okwenza kube nzima ukuhanjiswa kweoyile.Faka i-valve yeendlela ezintathu kumbhobho wamanzi we-condenser, kwaye ulungelelanise imilinganiselo ye-PID yesilawuli se-valve yeendlela ezintathu ngokuchanekileyo ukukhusela ulawulo olusuka kwi-oscillating.
Xa ioli engaphezulu ingena kwi-evaporator kwaye ixube kunye nefriji, inani elikhulu le-foam liya kuveliswa.Inkqubo yolawulo iya kukwazi ukubona le meko kwaye yenze impendulo echanekileyo.Xa i-foam iveliswa, umahluko wobushushu bokudluliselwa kobushushu kwi-evaporator uya kwanda kwaye wandise.I-valve iya kuvula ngokubanzi, ivumela i-refrigerant ngakumbi ukuba ingene kwi-evaporator, ikhulise inqanaba lefriji, ukwenzela ukuba ioli ifunwe yi-compressor kwaye ibuyele kwioli.
