Iyo inotonhora kamuri piston firiji compressor inotsamira pane inodzokorodza kufamba kwepiston kumanikidza gasi muhumburumbira. Kazhinji, kutenderera kweiyo prime mover inoshandurwa kuita inodzokorodza kufamba kwepiston kuburikidza ne crank-link mechanism. Iro basa rinoitwa ne crankshaft shanduko yega yega inogona kukamurwa kuita yekusveta maitiro uye kumanikidza uye kupera simba.
Mukushandiswa kwemazuva ese kwepiston firiji compressors, gumi nembiri zvikanganiso uye nzira dzadzo dzekugadzirisa dambudziko dzinorongwa sezvizvi:
1) Compressor inoshandisa mafuta akawanda
Chikonzero: Mukana pakati pekubereka, mhete yemafuta, silinda uye piston yakakura kwazvo, iyo inowedzera kushandiswa kwemafuta.
Mushonga: Ita zvinoenderana nekugadzirisa kana kutsiva zvikamu.
2) Kubata tembiricha yakanyanya
Zvikonzero: Mafuta ane tsvina, nzira yakavharwa yemafuta; mafuta asina kukwana; kudiki kwazvo clearance; eccentric wear of the bearing or roughening of the bearing bush.
Kubvisa: Chenesa dunhu remafuta, shandura mafuta ekuzora; kupa mafuta akakwana; gadzirisa clearance; shandura gwenzi rinobereka.
3) Simba rekugadzirisa simba rinokundikana
Chikonzero: Kumanikidzwa kwemafuta hakuna kukwana; mafuta ane refrigerant liquid; iyo oiri yekubuda kwevhavha yemuchina wekutonga yakasviba uye yakavharwa.
Kubvisa: Tsvaga chikonzero chekudzikira kwemafuta uye gadzirisa kudzvanywa kwemafuta; kudziya mafuta mu crankcase kwenguva yakareba; chenesa dunhu remafuta uye vharafu yemafuta kuita kuti mafuta edunhu asavharwe.
4) Exhaust tembiricha yakanyanya
Zvikonzero: mutoro mukuru; yakawandisa clearance volume; yakakuvara vharafu yekupedza uye gasket; hombe yekusveta superheat; kutonhora kwecylinder.
Kubvisa: kuderedza mutoro; gadzirisa kubviswa ne cylinder gasket; shandura chikumbaridzo ndiro kana gasket mushure mekuongorora; kuwedzera kuwanda kwemvura; kuwedzera kuwanda kwemvura inotonhorera.
5) Exhaust tembiricha yakaderera
Zvikonzero: iyo compressor inoyamwa mvura; vharafu yekuwedzera inopa mvura yakawandisa; mutoro wekutonhora hauna kukwana; iyo evaporator frost yakanyanya kukora.
Kubvisa: kuderedza kuvhurwa kwevhavha yekusveta; gadzirisa kugovera kwemvura kuti uite superheat yemhepo yekudzoka pakati pe5 ne10; gadzirisa mutoro; gara uchitsvaira kana kubvisa chando.
6) Kupedzwa kwemhepo kwakanyanyisa
Chikonzero: Dambudziko guru ndiro condenser, senge isina-condensable gasi muhurongwa; vharafu yemvura δ yakazaruka kana kuvhura hakusi kukuru, kudzvinyirira kwemvura kwakaderera zvikuru kukonzera mvura isina kukwana kana kutonhora kwemvura kwakanyanyisa; iyo air-cooled condenser fan δ yakavhurika kana vhoriyamu yemhepo Haina kukwana; Yakawandisa refrigerant charge (kana pasina mvura inogamuchira); Kunyanya tsvina mucondenser; Iyo compressor exhaust valve δ inovhurwa kusvika pakakwirira} Iyo pombi yekuburitsa haina kutsetseka.
Kubvisa: deflate pa-high-pressure exhaust end; vhura vharuvhu yemvura kuti uwedzere kudzvinyirira kwemvura; batidza fan kuti uderedze kuramba kwemhepo; bvisa yakawandisa refrigerant; kuchenesa condenser uye teerera kuhutano hwemvura; vhura vharafu yekupedza; bvisa pombi yekupedza.
7) Exhaust pressure yakanyanya kuderera
Zvikonzero: Kusakwana refrigerant kana kuvuza; kubuda kwemhepo kubva pavhavha yekupedza; kuwandisa kwemvura inotonhorera, tembiricha yemvura yakaderera, uye kudzorwa kwesimba kusina kunaka.
Kubvisa: kuona kudonha uye kubviswa kwekuputika, kuzadzazve refrigerant; kugadzirisa kana kuchinjwa kwezvidimbu zvevhavha; kuderedzwa kwemvura inotonhorera; kugadziriswa kwemagetsi ekugadzirisa magetsi
8) Wet compression (sando yemvura)
Zvikonzero: Iyo yemvura level ye evaporator yakanyanya kukwirira; mutoro wacho wakakurisa; vharafu yekukweva inovhurwa nekukurumidza.
Kubvisa: gadzirisa valve yekupa mvura; gadzirisa mutoro (gadzirisa chigadziro chekugadzirisa simba); vharafu yekusveta inofanira kuvhurwa zvishoma nezvishoma, uye inofanira kuvharwa kana pane nyundo yemvura.
9) Kumanikidzwa kwemafuta kwakanyanya
Chikonzero: Kugadziriswa kusina kunaka kwekumanikidzwa kwemafuta; pombi yakashata yemafuta; isina kururama mafuta pressure gauge.
Mushonga: gadzirisa mafuta ekumanikidza valve (zorora chitubu); tarisa uye uchenese pombi yemafuta; shandura geji yekumanikidza
10) Kumanikidzwa kwemafuta kwakanyanya kuderera
Zvinokonzera: Kusakwana kwehuwandu hwemafuta; kururamisa kusina kunaka; yakavharwa sefa yemafuta kana kuti yakavharwa mafuta inlet; pombi yemafuta yakasakara; (evaporator) kushanda kwevacuum.
Mushonga: kuwedzera mafuta; gadzirisa mafuta anodzvinyirira anogadzirisa valve} bvisa uye uchenese, bvisa kuvhara; gadzirisa pombi yemafuta; gadzirisa kushanda kuita kuti crankcase pressure ikwire kupfuura iyo airspheric pressure.
11) Kupisa kwemafuta kwakanyanya
Zvikonzero: tembiricha yekupedza yakanyanya; kutonhora kwemafuta hakuna kunaka; gungano clearance idiki zvakanyanya.
Kubvisa: Gadzirisa chikonzero chekumanikidza kwakanyanya; kuwedzera kuwanda kwemvura inotonhorera; gadzirisa clearance.
12) Motor overheating
Zvikonzero: low voltage, zvichikonzera ikozvino huru; mafuta asina kunaka; overload operation; isina-condensable gasi muhurongwa; kukanganisa kwekuvharidzirwa kwemagetsi emagetsi.
Kubvisa: tarisa chikonzero chekuderera kwemhepo uye kuibvisa; tarisa iyo lubrication system uye igadzirise; kuderedza mutoro wekushanda; bvisa isina-condensable gasi; tarisa kana kutsiva mota.
