1.Kuongorora zvinhu zvekutonhora kuchengetedza screw compressors
(1) Tarisa uone kana paine mavara asina kujairika mukati memuviri nepamusoro pevharuvhu inotsveyama, woyera saizi nekutenderera kwenzvimbo yemukati nedhayamita yemukati yegeji.
(2) Tarisa kana paine mavanga ekupfeka pazviso zvemahombe uye anotyairwa rotor uye kukweva uye kupera simba kwezvigaro.
（3） Tarisa kupfekwa kweiyo dhayamita yekunze uye mazino pamusoro peiyo huru uye inotyairwa rotors, uye kuyera dhayamita rekunze re rotor nekunze dhayamita dial gauge.
(4) Kuyera dhayamita yegomba guru re rotor uye dhayamita yemukati yegomba guru rinotakura, uye chengetedza kupfeka kwekutakura kukuru.
(5) Tarisa kupfeka kweshaft chisimbiso.
(6) Tarisa zvese "o" zvindori nezvitubu zve deformation uye kukuvara.
(7) Tarisa mamiriro eese emukati mafuta maseketi ecompressor.
(8) Tarisa uone kana chiratidzo chesimba chakakuvadzwa kana kuvharika.
(9) Tarisa piston yemafuta uye bharanzi piston yekupfeka zvisina kujairika.
(10) Tarisa uone kana iyo yekufambisa musimboti kana diaphragm yekubatanidza yakanganiswa.
2.Maintenance uye kukundikana kwe screw firiji
A.Kuyerera kwemvura inotonhora yakaderera
Mvura inotonhora inoyerera inoyerera switch haina kuvharwa, tarisa uye gadzirisa kuyerera kwekuchinja.
Pombi yemvura inotonhora haina kubatidzwa.
Ivhavha yekuvhara yepombi yemvura inotonhora haina kuvhurika.
B.Oil pressure alarm
Kupera kweoiri uye kunyange neoiri level switch alarm, oiri pressure alarm, oil pressure difference alarm.
Kwekushanda kwenguva refu pasi pemamiriro emutoro wakaderera, nzira yakanakisisa ndeyokuchengeta chikwata chichishanda pamutoro wakakwana.
Tembiricha yemvura inotonhorera yakadzikira (isingasviki 20 madhigirii), zvichiita kuti zviome kuchengetedza kupihwa kwemafuta nekumanikidza musiyano.
C.Alarm yekuyamwa yakaderera
Iyo yakaderera pressure sensor inotadza kana isina kubatwa zvakanaka, tarisa kana kuitsiva.
Kusakwana refrigerant charge kana unit leakage, cheki nekuchaja.
Yakavharwa sefa yakaoma, disassemble uye yakachena.
Kana kuvhurwa kwevharuvhu yekuwedzera kuri kudiki kwazvo, mota yekutsika inokuvadzwa kana isina kubatana, kutarisa, kugadzirisa kana kuitsiva.
D.High exhaust pressure alarm
Kana mvura inotonhorera isina kuvhurwa kana kuyerera kusina kukwana, kuyerera kunogona kuwedzerwa;
Iyo inotonhorera yemvura inotonhorera tembiricha yakakwira, tarisa inotonhorera shongwe mhedzisiro;
Mapaipi emhangura ari mucondenser akanyanya kusvibiswa, uye mapaipi emhangura anofanira kucheneswa;
Iko kune isina-condensable gasi muyuniti, kuburitsa kana vacuumize iyo unit;
Yakawandisa firiji inogona kudzoserwa kune inodiwa huwandu hwefiriji;
Iyo yekuparadzanisa ndiro mukamuri yemvura yecondenser iri hafu-kuburikidza, kugadzirisa kana kutsiva gasket yekamuri yemvura;
Iyo high pressure sensor inokundikana.Dzorera sensor.
E.Kukanganisa kwemafuta ekumanikidza kusiyana
Iyo economizer kana mafuta pressure sensor inotadza, itarise woitsiva.
Mafirita emukati nekunze akavharwa, tsiva sefa.
Oiri inopa solenoid valve kukundikana.Tarisa coil, solenoid valve, kugadzirisa kana kutsiva.
Pombi yemafuta kana vharafu yeimwe nzira yeboka repombi yemafuta yakashata, tarisa uye tsiva.
F.Kutonga kuti refrigerant charge haina kukwana
zvinoda kutariswa!Girazi rekuona pane pombi yemvura rinoratidza kuti mabhubhu haana kukwana kutonga kushaikwa kwefiriji;kutonhora kwemhepo yakanyanyisa hakuna kukwana kutonga kushayikwa kwefriji;inogona kutongwa nenzira dzinotevera:
Simbisa kuti chikwata chiri kushanda pasi pe100% mamiriro ekutakura;
Simbisa kuti tembiricha yemvura inotonhora yekubuda kweiyo evaporator iri pakati pe4.5 ne7.5 madhigirii;
Simbisa kuti mutsauko wetembiricha pakati pemvura inotonhora yekupinza nekubuda kweevaporator uri pakati pe5 ne6 madhigirii;
Simbisa kuti mutsauko wetembiricha yekupisa muevaporator uri pakati pe0.5 ne2 madhigirii;
Kana mamiriro ari pamusoro apa asina kusangana, uye kuvhurwa kwevhavha yekuwedzera yemagetsi yakakura kupfuura 60%, uye girazi rekuona rinoratidza mabhubhu, chinyorwa ichi chinobva kuRefrigeration Encyclopedia, zvichibva pane izvo zvinogona kutongwa kuti chikwata hachina refrigerant.Usawedzera mari nefiriji, sezvo izvi zvichizoguma nekukwirira kwekuyerera, kuwedzera kutonhorera kwemvura kushandiswa, uye pamwe kukuvadza kune compressor.
G.Wedzera refrigerant
Kuti usimbise kuti firiji yakakwana inowedzerwa, zvinodikanwa kuita kuti iyo unit irambe ichimhanya pasi pe100% mamiriro ekuremerwa, kuitira kuti tembiricha yemvura inotonhora yekubuda kweiyo evaporator iri 5 ~ 8 madhigirii, uye mutsauko wekushisa pakati pekupinza. uye mvura yekubuda nayo iri pakati pe5 ~ 6 madhigirii.Nzira yekutonga inogona kureva zvinotevera:
Kuvhura kwevharuvhu yekuwedzera kuri pakati pe40% ne60%;
Kusiyana kwekushisa kwekushisa kwe evaporator kuri pakati pe 0.5 ne 2 degrees;
Simbisa kuti chikwata chiri kushanda pasi pe100% mamiriro ekutakura;.
Wedzera mvura ine mvura yekuzadza vharafu kumusoro kwe evaporator kana kona vharafu pazasi;
Mushure mokunge chikwata ichimhanya zvakasimba, cherechedza kuvhurwa kwevhavha yekuwedzera yemagetsi;
Kana kuvhurwa kwevhavha yekuwedzera yemagetsi iri 40 ~ 60%, uye pane nguva dzose mabhubhu mugirazi rekuona, wedzera refrigerant yemvura;
H,kupomba refrigerant
zvinoda kutariswa!Usashandise compressor kupomba refrigerant kubva kune evaporator, nekuti kana suction pressure iri pasi pe1kg, inogona kukuvadza compressor.Shandisa mudziyo wekupomba wefiriji kupomba firiji.
(1) Tsiva iyo yakavakirwa-mukati mafuta sefa
Kana iyo unit ichimhanya kwemaawa 500 kekutanga, iyo mafuta sefa ye compressor inofanirwa kuongororwa.Mushure memaawa ega ega e2000 ekushanda, chinyorwa ichi chinobva kuRefrigeration Encyclopedia, kana kana musiyano wekumanikidzwa pakati pemberi nekumashure kwesefa yemafuta ukawanikwa uchipfuura 2.1bar, iyo sefa yemafuta inofanirwa kubviswa uye kuongororwa.
(2) Kana mamiriro maviri anotevera aitika, kudonha kwemafuta emafuta kunofanirwa kutariswa:
Iyo compressor inodzima nekuda kwearamu ye 'yakanyanya kudzvanywa kwemafuta musiyano mumafuta ekupa wedunhu';
Compressor inodzima nekuda kwe 'Oil level switch yadzimwa' alarm.
J.Oil filter replacement process
Dzima, dhonza compressor air switch off, vhara mafuta sefa yegadziriso vharafu, batanidza hose kuburikidza neoiri sefa yekugadziridza gomba, bvisa mafuta musefa yemafuta, vhura mafuta sefa plug, uye buritsa iyo yekare Oiri sefa. , mhete ye'O' yakanyorova nemafuta, isa sefa itsva yemafuta, tsiva nepuragi nyowani, tsiva mafuta ekuwedzera sefa (sefa yemafuta ekunze), dhonza mafuta sefa kuburikidza nesefa sevhisi port uye Kubatsira mweya musefa yemafuta, vhura sefa yemafuta. vharafu.
K,oiri level switch yadzimwa
Kana iyo unit ichidzokorodza maalarm nekuti iyo mafuta level switch yakabviswa, zvinoreva kuti mafuta ari muoiri separator haana kukwana uye yakawanda yemafuta iri muevaporator.Kana iyo mafuta level switch inogara yakabviswa, shandisa pombi yemafuta kuwedzera marita maviri emafuta kune inoparadzanisa mafuta, usawedzera mafuta mune chero imwe nzvimbo, simbisa kuti iyo mafuta level switch yakavharwa, tangazve unit, uye mhanya. pa 100% mutoro kweinenge 1 awa pasi pemamiriro akajairika.
L.Mafuta ekumhanya
Zvikonzero zvekumhanya kwemafuta: yakaderera kupera kwepamusoro dhigirii inotungamira kune kushomeka kwemafuta ekuparadzanisa, uye yakazara yekupisa tembiricha yeyuniti yakadzikira (inotonhorera tembiricha yemvura yakadzikira), zvichikonzera kuderera kwemafuta ekudzvinyirira, izvo zvinoita kuti kutenderera kwemafuta kuome.Isa vharuvhu yenzira nhatu papombi yemvura yecondenser, uye gadzirisa iyo PID paramita yenzira nhatu-yevhavha controller nenzira kwayo kudzivirira kutonga kubva pakutenderera.
Kana mafuta akawandisa achipinda muevaporator uye anosanganiswa nefiriji, huwandu hwakawanda hwefuro huchagadzirwa.Iyo control system ichakwanisa kuona mamiriro aya uye kuita mhinduro chaiyo.Kana furo ragadzirwa, mutsauko wekushisa wekushisa mu evaporator uchawedzera nekuwedzera.Ivhavha ichazarura yakafara, ichibvumira kuti firiji yakawanda ipinde mu evaporator, ichiwedzera chiyero chefriji, kuitira kuti mafuta anoyamwa ne compressor uye adzokere kumafuta.
