Refrigeration Compressor Troubleshooting

Kunyanya kupisa tembiricha yekukweva kunonyanya kukonzerwa nekuwedzera kusveta kupisa kwakanyanya.Cherechedzo: Tembiricha yekusveta yakakwirira hazvirevi kuti kusveta kwakakwira nekuti kunopisa zvakanyanya.Kazhinji, cylinder head of compressor inofanira kunge iri hafu yekutonhora uye hafu inopisa.Kana tembiricha yekutora yakanyanya kukwirira, musoro wecylinder unopisa.Kana tembiricha yekuyamwa yakakwira kupfuura iyo yakatemwa kukosha, tembiricha yekubuda gasi inokwira zvinoenderana.

Chikonzero:

a.Iyo firiji haina kukwana.Kunyange kana vharafu yekuwedzera inoshanda zvakanyanya, hapana shanduko mune yemvura inopihwa, iyo refrigerant tembiricha yakakwira muevaporator kuitira kuti kusimudza tembiricha yekuyamwisa.

b.Ivhavha yekuwedzera inoshanda mune zvishoma.Kutenderera kwefiriji yehurongwa hakuna kukwana, shoma refrigerant inopinda muevaporator, yakakwira superheat, yakanyanya kusveta tembiricha.

c.Sefa yevharuvhu yekuwedzera yakavharwa.Huwandu hwemvura inopihwa mu evaporator haina kukwana, huwandu hwefiriji mvura inoderedzwa, uye chikamu chenzvimbo ye evaporator inogarwa nemhepo inopisa, saka tembiricha yemhepo yekupinda inowedzera.

d.zvimwe zvikonzero.

a.Iyo refrigerant charge yakawandisa, inobata chikamu chenzvimbo mukati meiyo condenser, kuitira kuti iyo condensing pressure yakakwira, uye mvura inopinda muevaporator inowedzera.Mvura iri mu evaporator haigoni kunyungudutswa zvachose, kuitira kuti gasi rinoyamwa ne compressor rine madonhwe emvura.Saka, tembiricha yemhepo inodzoka duct inotonhorera pasi, asi tembiricha inoputika haichinji nekuti kudzvanywa hakudzike, uye kupisa kwakanyanya kunoderera.Kunyangwe kana kugadzirisa vharafu yekuwedzera, hapana kuvandudzwa kwakawanda.

b.Dhigirii yekuvhura yevharuvhu yekuwedzera yakakura zvakanyanya.Nekuti tembiricha sensor yakasungirirwa zvakasununguka, nzvimbo yekusangana neinodzosera pombi yemhepo idiki, kana tembiricha sensor haina kuputirwa neyakavharira kupisa zvinhu uye nzvimbo yekuputira haina kunaka, tembiricha yakayerwa ne sensor tembiricha haina kurongeka, padhuze. iyo ambient tembiricha, uye vharafu yekuwedzera inoshandiswa.Dhigirii rekuvhura rinowedzera, zvichikonzera kuwanda kwemvura.

Chikonzero:

Iyo refrigerant charge haina kukwana uye ichave nechando kubva kune evaporator kuenda kune compressor (Cherechedza: inoda kuongororwa).Uye zvakare, nekuda kwezvikonzero zvekunze, iyo refrigerant haina kubuda zvakanaka kana kuti haina kubuda zvachose muevaporator, izvo zvinogona kukonzera kutonhora kwakanyanya kana kutomanikidza kunyorova.(Kana air-conditioning yepakati ikadzokera kumhepo yakashata kana sefa yekufefetera yakavharika zvakanyanya, pombi yekutonhodza inoomesa nechando uye tembiricha inopedza simba yakadzikira.) Pombi haina kuvharirwa zvakanaka kana kuti pombi yakarebesa. , izvo zvinogona kukonzera tembiricha yekukweva kwemhepo yakakwirira.

3. Exhaust tembiricha haina kujairika

Zvinogona kuitika: adiabatic kukosha, compression ratio, tembiricha yekuyamwisa.

Iyo compressor discharge tembiricha inogona kuverengwa kubva kune thermometer pamutsara wekuburitsa.Iyo ine hukama neadiabatic index yefiriji, iyo compression ratio (condensation pressure / evaporation pressure), uye tembiricha yekuyamwisa.Kukwirira tembiricha yekusveta, ndiko kuwedzera kwereshiyo yekumanikidza uye kukwirisa tembiricha yekuburitsa.

Kana kusveta kunowedzera nguva dzose, kupisa kwemhepo yegesi kunokwira apo mhepo inopisa inowedzera;kana kupera kwemhepo kusingashanduki, kupisa kwegesi kwemhepo kunokwirawo kana kusveta kuderera kunoderedzwa, zvose zviri zviviri zvinokonzerwa nekuwedzera kwehuwandu hwekugadzirisa.Kuwedzera kupisa tembiricha uye tembiricha yekupedza zvinokanganisa kushanda kwecompressor uye inofanirwa kudzivirirwa.Kunyanya kupisa kwemhepo tembiricha kunogona kuita kuti mafuta ekuzora ave mutete kana kutopisa uye coke, izvo zvinokanganisa mamiriro ekuzora ecompressor.

Kupisa kwegasi rekubuda kwemhepo kunoenzanirana nereshiyo yekumanikidza (condensation pressure / evaporation pressure) uye tembiricha yekuyamwisa.Kana iyo yakanyanya kupisa yekudziya tembiricha yakakwira uye iyo compression reshiyo yakakwira, tembiricha yekubuda gasi inokwira.Kana iyo yekusveta kudzvanywa uye tembiricha ikasachinja, tembiricha yekubuda gasi inokwirawo sezvo kupedzwa kwemhepo kunowedzera.

Zvikonzero zvikuru zvekuwedzera kwekushisa kwekubuda

a.yakanyanya kusveta tembiricha.Mushure mefiriji mhute yakatsikirirwa uye tembiricha yekuburitsa inokwira.

b.Iyo tembiricha yekudziya inokwira kumusoro zvekuti condensing pressure yakakwira futi.zvichiita kuti tembiricha yekusimuka ikwire.

c.Iyo yekupedza valve ndiro inopwanyika, iyo yakanyanya kudzvanywa mutsindo inodzokororwa uye tembiricha inokwira, silinda uye silinda musoro zvinopisa, uye iyo thermometer inoratidza kukosha papombi yekuburitsa inokwira zvakare.

Izvo zvinhu chaizvo zvinokanganisa kukwira kwekushisa kwekutamisa ndezvi: kutonhora kwepakati kwepakati kwakadzikira, kana kuwanda kwechiyero muintercooler kunokanganisa kuchinjisa kupisa, tembiricha yekusveta yedanho rekupedzisira rinenge rakakwirira, uye tembiricha yekutamisa inowedzerawo.Iyo gasi vharafu inodonha uye piston mhete inodonha, iyo isingangokanganisa kukwira kwekushisa kwekutamisa, asi zvakare inoshandura iyo interstage pressure.Chero bedzi iyo compression ratio yakakwira kupfuura kukosha kwakajairika, tembiricha yekutamisa inokwira.Daming Refrigerationinokuyeuchidza kuti michina yakanyoroveswa nemvura inoshaya mvura kana kusakwana kwemvura inozowedzera tembiricha yekubuda.Iyo condensing pressure haina kujairika uye exhaust pressure inodzikiswa.

4.high exhaust pressure

Iyo exhaust pressure inowanzoenderana nehuwandu hwetembiricha yekunyungudika.Pasi pemamiriro akajairwa, iyo compressor discharge pressure iri padyo zvakanyanya neiyo condensing pressure.High exhaust pressure inowedzera simba rekumanikidza uye kuderedza gasi rekutapurirana coefficient, nekudaro kudzikisa kutonhora kunoshanda.

Sezvo iyo condensing pressure inowedzera, iyo compressor discharge tembiricha inokwirawo.Chiyero chekumanikidza che compressor chinowedzera, uye gasi rekufambisa coefficient rakaderedzwa, kuitira kuti firiji simba re compressor rideredzwe.Kushandiswa kwemagetsi kwawedzera.Kana tembiricha yekupisa gasi yakakwira zvakanyanya, kushandiswa kwecompressor lubricating mafuta kunowedzera, mafuta anoomeswa, uye mafuta anokanganisa;kana tembiricha yegesi yekubuda iri padhuze nekupenya kwemafuta ecompressor, chikamu chemafuta ekuzora chakagadzirwa nekabhoni uye chakaunganidzwa mukusveta, Iyo yekuburitsa valve port inokanganisa kuiswa chisimbiso kwevhavha.

Kuderedza tembiricha yepakati yekutonhora kunogona kuita kuti tembiricha ye condensation iderere uye kudzvanywa kwe condensation kuderera, asi izvi zvinoganhurwa nemamiriro ekunze uye zvakaoma kusarudza.Kuwedzera kuyerera kwepakati yekutonhora kunoderedza kutonhora kwe condensation (iyi nzira inoshandiswa zvakanyanya).Zvisinei, hazvibviri kuwedzera kuyerera kwemvura inotonhorera kana mhepo unilaterally, sezvo izvi zvichawedzera simba repombi yemvura inotonhorera kana fan uye motokari, uye inofanira kunyatsotariswa.

5. kupera kusina kukwana

Kusakwana kusimuka - kunyanya kuenzaniswa neyakagadzirirwa kutamiswa kwecompressor, ndeimwe yeanonyanya kutadza kutadza kwe compressor, kunyanya nekuda kwezvikonzero zvakati:

1. Sefa yekutora yakasvibiswa kana kuti compressor suction pipe yakareba, uye dhayamita yepombi idiki, izvo zvinoita kuti kupikisa kuwedzere kuwedzera, izvo zvinokanganisa mhepo inopinza uye inoderedza kubuda kwegesi.

2. Iyo compressor kumhanya inoderedzwa kuderedza vhoriyamu yekupedza.Sezvo kutamiswa kwecompressor kwakagadzirwa zvinoenderana nehumwe hurefu (kunyanya air compressor), tembiricha yekupinda, humidity uye magetsi, kana ichishandiswa munzvimbo inodarika chiyero chiri pamusoro, senge air compressor inoshandiswa mubani inokonzeresa. kusveta kudzvinyirirwa kuderera, nezvimwewo, uye kutamiswa kuchakanganiswawo.

3, chisimbiso chekurongedza hachina kuomarara, zvichikonzera kuvuza, kuitira kuti vhoriyamu yekuburitsa ideredze.Chokutanga pane zvose, zvingave kuti iyo yekuzadza pachayo haina kukodzera;chechipiri, inogona kukonzerwa nekubuda kwemhepo panguva yekuisa, senge abrasion kana kushungurudza.Kazhinji, iyo yekuzadza inozadzwa nemafuta ekuzora, ayo anogona kukwizwa, kuvharwa uye kutonhorera.
