Refrigeration Compressor Troubleshooting

Kunyanya kupisa tembiricha yekukweva kunonyanya kukonzerwa nekuwedzera kusveta kupisa kwakanyanya. Cherechedzo: Tembiricha yekusveta yakakwira 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 yekusveta yakakwira kupfuura kukosha kwakatemwa, 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 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 yakasungwa zvakasununguka, nzvimbo yekusangana neinodzosera pombi yemhepo idiki, kana tembiricha sensor haina kuputirwa nezvinhu zvinodzivirira kupisa uye nzvimbo yekuputira haina kunaka, tembiricha yakayerwa ne sensor tembiricha haina kurongeka, padhuze. iyo ambient tembiricha, uye vharafu yekuwedzera inoshandiswa. Dhigirii yekuvhura inowedzera, 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 chando chakanyanya kana kutomanikidza kunyorova. (Kana air-conditioning yepakati ikadzokera kumhepo yakashata kana sefa yekufefetera yakavharika zvakanyanya, pombi yechando inotonhora uye tembiricha inopedza simba yakadzikira.) Pombi haina kuvharwa zvakanaka kana kuti pombi yakarebesa. , izvo zvinogona kukonzera tembiricha yekukweva kwemhepo yakakwirira.

3. Exhaust tembiricha haina kujairika

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

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

Kana kusveta kunowedzera nguva dzose, kupisa kwegesi kwemhepo 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 tembiricha yekupedza simba kunogona kuita kuti mafuta ekuzora ave mutete kana kutopisa uye coke, izvo zvinokanganisa mamiriro ekuzora ecompressor.

Kupisa kwegasi rekubuda kwemhepo kunoenderana neiyo compression ratio (condensation pressure / evaporation pressure) uye tembiricha yekuyamwa. Kana iyo superheat yekudziya tembiricha yakakwira uye iyo compression ratio yakakwira, tembiricha yekubuda gasi ichave yakakwirira. Kana iyo yekusveta kumanikidza uye tembiricha ikasachinja, tembiricha yekubuda gasi inokwirawo sezvo simba rekubuda rinowedzera.

Zvikonzero zvikuru zvekuwedzera kwekushisa kwekubuda

a. yakakwirira yekusveta tembiricha. Mushure mefiriji mhute yakatsikirirwa uye tembiricha yekubuda yakakwira.

b. Iyo tembiricha yekumisikidza inokwira kuti condensing pressure ikwire, futi. zvichiita kuti tembiricha yekutamisa ikwire.

c. Iyo yevharuvhu ndiro inopwanyika, iyo yakanyanya kudzvanywa mutsindo inodzokororwa uye tembiricha inokwira, silinda uye cylinder 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 kuchinjana kwekupisa, tembiricha yekusveta yedanho rekupedzisira inenge yakakwira, uye tembiricha yekutamisa inowedzerawo. Iyo gasi vharafu inodonha uye piston mhete inodonha, iyo isingangokanganisa kukwira kwekushisa kwekutamisa, asi zvakare inoshandura interstage pressure. Chero bedzi iyo compression ratio yakakwira kupfuura kukosha kwakajairika, tembiricha yekutamisa inokwira.Daming Refrigerationinokuyeuchidza kuti michina yakanyoroveswa nemvura inoshaya mvura kana kuti mvura isina kukwana ichawedzera 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 kwakanaka.

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 kupisa kwegasi kunopisa kwakanyanya, kushandiswa kwecompressor lubricating mafuta kunowedzera, mafuta anoderedzwa, uye kusvibiswa kunokanganisa; kana tembiricha yegesi yekubuda iri padhuze nekupenya kwemafuta ecompressor, chikamu chemafuta ekuzora chakagadzirwa nekabhoni uye chakaunganidzwa mukusveta, Iyo exhaust valve port inokanganisa kuiswa chisimbiso kwevhavha.

Kuderedza tembiricha yemhepo inotonhorera kunogona kuita kuti tembiricha ye condensation idonhe uye kuti condensation pressure iderere, asi izvi zvinoganhurwa nemamiriro ekunze uye zvakaoma kusarudza. Kuwedzera kuyerera kwemhepo inotonhorera kunoderedza kupisa kwemhepo (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 kwe compressor, ndeimwe yeanonyanya kutadza kutadza kwe compressor, kunyanya nekuda kwezvikonzero zvakati:

1. Firita yekutora yakasvibiswa kana kuti compressor suction pipe yakarebesa, uye dhayamita yepombi iduku kwazvo, 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 chekutakura hachina kuomarara, zvichikonzera kuvuza, kuitira kuti vhoriyamu yekuburitsa ideredzwe. 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.
