Refrigeration Compressor Troubleshooting

Mocheso o phahameng ka ho fetesisa oa ho huloa haholo-holo o bakoa ke ho eketseha ha mocheso o matla.Tlhokomeliso: Mocheso o phahameng oa mocheso ha o bolele hore khatello ea ho huloa e phahame hobane ke mouoane o chesang haholo.Hangata, hlooho ea cylinder ea compressor e lokela ho ba halofo e batang le halofo e chesang.Haeba mocheso o kenang o phahame haholo, hlooho ea silinda e tla futhumatsa.Haeba mocheso oa ho hula o phahame ho feta boleng bo tsitsitseng, mocheso oa khase ea ho tsoa o tla nyoloha ka tsela e nepahetseng.

Lebaka:

a.Sehatsetsi ha sea lekana.Esita le haeba valve ea katoloso e sebetsa haholo, ha ho na phetoho phepelong ea mokelikeli, hore mocheso oa sehatsetsing o phahame ka mouoane e le hore o phahamise mocheso o monyang.

b.Sephahla sa ho atolosa se sebetsa ka mokhoa o fokolang.Ho potoloha ha sehatsetsing sa sistimi ha hoa lekana, sehatsetsi se tlase se kena ka har'a mouoane, mocheso o phahameng haholo, mocheso o monyang o phahameng.

c.Sefefo sa valve ea katoloso se koalehile.Palo ea phepelo ea mokelikeli ka har'a mouoane ha e lekane, palo ea mokelikeli oa sehatsetsing e fokotsehile, 'me karolo ea sebaka sa mouoane e sebelisoa ke mouoane o chesang haholo, kahoo mocheso oa moea o kenang oa eketseha.

d.mabaka a mang.

a.Tefiso ea sehatsetsing e ngata haholo, e nka karolo ea sebaka ka hare ho condenser, e le hore khatello ea condensing e phahame, 'me mokelikeli o kenang mouoane o eketsehe.Mokelikeli o ka har'a mouoane o ke ke oa fetoha mouoane ka ho feletseng, e le hore khase e anngoeng ke compressor e na le marotholi a metsi.Kahoo, mocheso oa pompo ea moea o pholileng o theoha, empa mocheso oa mouoane ha o fetohe hobane khatello ha e fokotsehe, 'me mocheso o matla oa fokotseha.Esita le haeba u fetola valve ea ho atolosa, ha ho na ntlafatso e ngata.

b.Tekanyo ea ho bula ea valve ea ho atolosa e kholo haholo.Hobane sensor ea mocheso e tlameletsoe ka mokhoa o hlephileng, sebaka sa ho kopana le phala ea moea e khutlelang e nyenyane, kapa mochine oa mocheso ha o phuthetsoe ka thepa e sireletsang mocheso 'me boemo ba ho phuthela bo fosahetse, mocheso o lekantsoeng ka mochine oa mocheso ha o nepahale, o haufi le mocheso o potolohileng, 'me valve ea ho atolosa e sebetsa.Tekanyo ea ho bula e eketseha, e bakang phepelo ea metsi e ngata haholo.

Lebaka:

Tefiso ea sehatsetsi ha ea lekana 'me e tla hoamisoa ho tloha mouoane ho ea ho compressor (Hlokomela: e hloka ho netefatsoa).Ho phaella moo, ka lebaka la mabaka a ka ntle, sehatsetsing ha se fetohe mouoane hantle kapa esita le ho se fetohe mouoane ho hang ka mouoane, se ka bakang serame se matla kapa esita le ho hatella ka metsi.(Haeba air-conditioning e bohareng e khutlela moeeng hampe kapa filthara ea air-conditioning e thibiloe ka botebo, phala ea chiller e tla hoamisoa 'me mocheso o khathatsang o tlase haholo.) , e ka bakang mocheso oa moea oa ho huloa holimo.

3. Mocheso oa mocheso ha o tloaelehe

Lintlha tse ka bang teng: boleng ba adiabatic, karo-karolelano ea khatello, mocheso o monyang.

Thempereichara ea ho tsoa ha compressor e ka baloa ho tsoa ho thermometer moleng oa ho tima.E amana le index ea adiabatic ea sehatsetsing, tekanyo ea khatello (khatello ea condensation / khatello ea mouoane), le mocheso o monyang.Ha mocheso o monya o phahame, ho ba le tekanyo e phahameng ea khatello le mocheso o phahameng oa ho ntša metsi.

Ha khatello ea ho hula e sa khaotse, mocheso oa khase ea ho tsoa o phahama ha khatello ea ho ntša metsi e eketseha;haeba khatello ea ho qeta e sa fetohe, mocheso oa khase ea ho qeta o boetse oa phahama ha khatello ea ho hula e fokotseha, ka bobeli e bakoa ke ho eketseha ha tekanyo ea khatello.Lithempereichara tse fetelletseng tsa condensing le lithempereichara tsa mouoane li kotsi ts'ebetsong ea komporo mme li lokela ho qojoa.Lithempereichara tse phahameng haholo tsa ho ntša metsi li ka etsa hore oli e tlotsang e fokotsehe kapa e chese le coke, e leng se senyang maemo a ho tlotsa a compressor.

Thempereichara ea khase ea ho tsoa e lekana le tekanyo ea khatello (khatello ea condensation / khatello ea mouoane) le mocheso o monyang.Haeba mocheso o phahameng oa mocheso oa ho hula o phahame 'me tekanyo ea khatello e phahame, mocheso oa khase ea ho tsoa o tla ba holimo.Haeba khatello ea ho hula le mocheso li sa fetohe, mocheso oa khase ea ho tsoa o boetse oa phahama ha khatello ea ho ntša metsi e ntse e eketseha.

Mabaka a ka sehloohong a ho eketseha ha mocheso oa ho ntša mocheso

a.mocheso o phahameng oa ho hula.Ka mor'a hore mouoane oa sehatsetsing o hateletsoe 'me mocheso oa ho ntša metsi o phahame.

b.Thempereichara ea condensing e ea nyoloha e le hore khatello ea condensing e phahame, le eona.ho baka hore mocheso wa phalliso o phahame.

c.Letlapa la li-valve tsa ho ntša metsi le pshatlehile, mouoane oa khatello e phahameng o hatelloa khafetsa 'me mocheso oa phahama, cylinder le hlooho ea cylinder lia chesa,' me boleng ba pontšo ea thermometer holim'a phala ea ho tima le bona boa phahama.

Lintlha tsa sebele tse amang ho phahama ha mocheso oa ho falla ke: ts'ebetso ea ho pholisa bohareng e tlaase, kapa tekanyo e feteletseng ea intercooler e ama phapanyetsano ea mocheso, mocheso oa mocheso oa mohato oa ho qetela o hlile o phahame, 'me mocheso oa ho falla o boetse oa eketseha.Ho lutla ha valve ea khase 'me selikalikoe sa piston sea lutla, se sa ameng feela ho phahama ha mocheso oa phallo, empa hape se fetola khatello ea lipakeng.Ha feela tekanyo ea compression e phahame ho feta boleng bo tloaelehileng, mocheso oa ho falla o tla nyoloha.Sehatsetsi se Daminge u hopotsa hore mechine e pholileng ka metsi e haelloa ke metsi kapa metsi a sa lekaneng a tla eketsa mocheso oa ho tsoa.Khatello ea condensing e sa tloaeleha 'me khatello ea ho qeta e theohile.

4.khatello e phahameng ea ho qeta

Khatello ea ho qeta hangata e amana le boemo ba mocheso oa condensing.Tlas'a maemo a tloaelehileng, khatello ea khatello ea compressor e haufi haholo le khatello ea condensing.Khatello e phahameng ea ho felloa ke matla e tla eketsa matla a khatello le ho fokotsa coefficient ea phetisetso ea khase, kahoo e fokotsa ts'ebetso ea ho pholisa.

Ha khatello ea condensing e ntse e eketseha, mocheso oa compressor discharge le ona oa phahama.Karolelano ea khatello ea compressor e eketseha, 'me coefficient ea phetisetso ea khase e fokotsehile, e le hore matla a sehatsetsing a compressor a theohe.Tšebeliso ea matla e eketsehile.Haeba mocheso oa khase ea ho tsoa o phahame haholo, tšebeliso ea oli ea compressor lubricating e eketseha, oli e fokotsehile, 'me lubrication e ameha;ha mocheso oa khase ea ho qeta o le haufi le sebaka se khanyang sa oli ea compressor, karolo ea oli e tlotsang e na le carbonized 'me e bokelloa ka ho hula, The exhaust valve port e ama ho tiisoa ha valve.

Ho fokotsa mocheso oa sebaka sa ho pholisa ho ka etsa hore mocheso oa condensation o theohe le khatello ea condensation e fokotsehe, empa sena se lekanyelitsoe ke maemo a tikoloho 'me ho thata ho khetha.Ho eketsa lebelo la ho phalla ha mocheso o pholileng ho fokotsa mocheso oa condensation (mokhoa ona o sebelisoa haholoanyane).Leha ho le joalo, ho ke ke ha khoneha ho eketsa phallo ea metsi a pholileng kapa moea o le mong, kaha sena se tla eketsa matla a pompo ea metsi a pholileng kapa fan le motlakase, 'me e lokela ho nkoa ka ho pharaletseng.

5. ho felloa ke matla ho lekaneng

Ho falla ho sa lekaneng - haholo ha ho bapisoa le phallo e hlophisitsoeng ea compressor, ke e 'ngoe ea tse atisang ho hloleha ho hloleha ha compressor, haholoholo ka mabaka a' maloa:

1. Sesepa sa ho kenya se silafalitsoe kapa phala ea compressor suction e telele haholo, 'me bophara ba pipe e nyenyane haholo, e leng se etsang hore khanyetso ea ho tsuba e eketsehe, e amang molumo oa moea o kenang le ho fokotsa molumo oa khase ea ho tsoa.

2. Lebelo la compressor le fokotsehile ho fokotsa molumo oa ho qeta.Kaha ho falla ha compressor ho entsoe ho ea ka bophahamo bo itseng (haholo-holo moea compressor), mocheso o kenang, mongobo le phepelo ea motlakase, ha e sebelisoa sebakeng se fetang maemo a ka holimo, joalo ka ha ho sebelisoa moea oa compressor sebakeng se bataletseng. khatello ea ho hula ho fokotseha, joalo-joalo, le ho falla le hona ho tla ameha.

3, tiiso ea ho paka ha e thata, e bakang ho lutla, e le hore molumo oa ho tima o fokotsehe.Pele ho tsohle, e ka 'na ea e-ba hore ho tlatsa ka boeona ha hoa tšoaneleha;ea bobeli, e ka bakoa ke ho lutla ha moea nakong ea ho kenya, joalo ka abrasion kapa khatello.Ka kakaretso, setlolo se tlatsitsoe ka oli e tlotsang, e ka tlotsoang, ea koaloa le ho pholile.
