Mokhoa oa ho rarolla mathata oa ketsahalo ea hore mokelikeli oa compressor o otla silinda ka indasteri chiller tsamaiso

1. Lisosa tsa ho hloleha ha stroke se metsi

① Ha u sebelisa taolo ea matsoho, valve ea throttle ha e lokisoe ka tsela e nepahetseng, ho bula ho hoholo haholo, kapa valve ea float ha e koaloe ka thata;

②Valfo ea ho atolosa mocheso ha e sebetse, kapa tleloubu e lemohang mocheso e kentsoe ka phoso, ‘me ho kopana ha se nnete, ho bakang ho buloa ho feteletseng;

③Koele ea mouoane e tenya haholo mme mojaro o monyane haholo;

④ Ho bokella oli ho feteletseng tsamaisong;

⑤Bokhoni ba ho pholisa ba compressor bo boholo haholo, kapa mojaro oa mocheso oa ntlo ea polokelo o nyane;

⑥ Phetoho e fosahetseng ea ts’ebetso ea valve;

⑦ Sehatsetsi se ka har’a tsamaiso ea sehatsetsi se tletse sehatsetsi se ngata haholo;

⑧The valve solenoid e fanang ka metsi ha e koaloe ka thata;

⑨Mokhahlelong oa sehatsetsing sa methati e ‘meli, ha valve ea khatello e tlase e koaloa kapa e buloa ka tšohanyetso (kapa palo ea likarolo tsa ts’ebetso e fokotseha ka tšohanyetso le ho eketseha), le ka har’a intercooler. Koala ea noha ka tšohanyetso e kena ka har’a mokelikeli, e ka bakang habonolo leqeba le metsi la compressor ea boemo bo phahameng ba khatello.

Ka bokhutšoanyane, ho na le lintlha tse ngata tse bakang ho otloa ke metsi ha compressor, ‘me mabaka a lokela ho fumanoa le ho felisoa ho ea ka boemo bo itseng.

2. Lisebelisoa, lisebelisoa le lisebelisoa tse sebelisetsoang ho lemoha ho hlōleha ha sekhahla se metsi sa compressor ea sehatsetsing.

① Sesebelisoa: tekanyo ea khatello, multimeter, clamp meter, thermometer, habeli qi meter.

② Lisebelisoa: li-wrenches, lisebelisoa tsa ho atolosa liphaephe, li-valve tsa ho tlatsa, li-pliers tse nchocho, li-pliers, litoche, lisebelisoa tse khethehileng.

③ Thepa: botlolo ea mokelikeli o sebetsang, botlolo ea naetrojene, pompo ea vacuum, sete e felletseng ea tjheseletso ea khase.

3. Mokhoa o tloaelehileng oa ts’ebetso ea ho lemoha ho hlōleha ha setorouku se metsi sa compressor ea sehatsetsing

Kaha tsamaiso ea sehatsetsing ea li-chillers tsa indasteri ke mokhoa o rarahaneng o entsoeng ka li-condensers, li-evaporators, li-valve tsa ho atolosa, le lisebelisoa tse ngata tsa lisebelisoa tse amanang le ho susumetsa tse ling, hang ha sesebelisoa sa sehatsetsi se hlōleha, motho ha aa lokela ho tsepamisa maikutlo feela ho tse itseng Boemong ba sebaka sa heno. hoa hlokahala ho etsa tlhahlobo e felletseng le tlhahlobo e felletseng ea sistimi eohle. Ka bokhutšoanyane, mokhoa o tloaelehileng oa ho lemoha ke:

“Ho mamela motho a le mong, ho ama tse peli, ho sheba tse tharo, ho hlahloba tse ‘nè” sehlopha sa mekhoa ea motheo.

Ponahalo e le ‘ngoe: sheba khatello ea ho hula le khatello ea ho ntša khatello ea compressor; sheba lebelo la ho pholile la kamore e pholileng; sheba boemo ba serame sa mouoane; sheba boemo ba serame sa valve ea ho atolosa mocheso.

Ho mamela ha bobeli: ho mamela molumo oa compressor e mathang, ho lokela ho ba le motsamao o hlakileng oa valve feela. Ha ho utloahala molumo oa “ho feta”, ke molumo o matla oa hamore ea metsi; mamela molumo oa sehatsetsi se phallang ka valve ea ho atolosa; mamela molumo oa fene e pholileng; mamela molumo oa valve ea solenoid; mamela hore na ho na le ho thothomela ho totobetseng.

Ho ama tse tharo: ama mocheso oa li-bearings tse ka pele le tse ka morao tsa compressor; ama mocheso oa compressor cylinder liner le hlooho ea cylinder; ama mocheso oa liphaephe tsa ho hula le ho ntša metsi. Litlhahlobo tse ‘nè: Sebelisa likhopolo tse amehang tsa sesebelisoa sa sehatsetsing ho hlahloba le ho ahlola ketsahalo ena, ho fumana sesosa sa ho hlōleha, le ho e felisa ka mokhoa o lebisitsoeng. Kahlolo ea ho hloleha ha hamore ea mokelikeli ha e thehiloe feela holim’a serame sa phala ea ho hula, empa haholo-holo ho tloha ho theoha ho matla ha mocheso oa mocheso. Ka nako ena, khatello ea ho ntša metsi e ke ke ea fetoha haholo, empa silinda, crankcase le kamore ea ho ntša metsi kaofela lia ameha. Mohatsela kapa serame. Tabeng ea hydraulic shock, e ka senya tsamaiso ea lubrication, ea mpefatsa mosebetsi oa pompo ea oli, ea fokotsa ka matla lebota la silinda, ‘me ea phunya hlooho ea silinda maemong a boima.

4. Mokhoa oa ho rarolla mathata le ho khutlisetsa ts’ebetso e tloaelehileng ea sehatsetsi sa compressor wet stroke

Ho sebetsana le likotsi tsa ho sisinyeha ha metsi ho lokela ho etsoa hang-hang, ‘me maemong a tebileng, ho sebetsana le likoloi tsa tšohanyetso ho lokela ho etsoa. Ha setorouku se senyenyane sa metsi se etsahala ka har’a mohatla o le mong, valve ea ho hula ea compressor feela e lokela ho koaloa, valve ea ho fana ka metsi ea tsamaiso ea mouoane e lokela ho koaloa, kapa mokelikeli o ka har’a setshelo o fokotsehe. noodle. ‘Me u ele hloko khatello ea oli le mocheso oa ho qeta. Ha mocheso o nyolohela ho 50 ℃, leka ho bula valve ea ho hula. Haeba mocheso oa mocheso o ntse o phahama, o ka tsoela pele ho o bula, ‘me haeba mocheso o theoha, o koale hape.

Bakeng sa “motsoako oa metsi” oa compressor ea mekhahlelo e ‘meli, mokhoa oa phekolo oa sekhahla se tlaase sa khatello ea metsi se tšoana le se nang le sekhahla se le seng. Empa ha ho na le ammonia e ngata e kenang ka har’a cylinder, compressor e nang le khatello e phahameng e ka sebelisoa ho fokotsa khatello ea maikutlo le ho tsoa ka intercooler. Pele o pompa fatše, mokelikeli o ka har’a intercooler o lokela ho tšeloa ka nkhong ea drain, ebe khatello e lokela ho fokotseha. Sekoti sa metsi a pholileng a cylinder le oli e lokela ho pholile pele ho fokotsa khatello: tlosa metsi a pholileng ka sesebelisoa kapa u bule valve e kholo ea metsi.

Ha boemo ba mokelikeli oa intercooler bo phahame haholo, compressor e nang le khatello e phahameng e bontša “stroke e metsi”. Mokhoa oa phekolo o lokela ho qala ka ho tima valve ea ho monya ea konpresser e tlaase, ebe o tima valve ea ho monya ea khatello e phahameng ea khatello le valve ea phepelo ea metsi ea intercooler. Haeba ho hlokahala, tšela metsi a ammonia ka har’a intercooler ka moqomong oa ho ntša metsi. Haeba konpresser e nang le khatello e phahameng e bata haholo, emisa compressor ea khatello e tlase. Mokhoa o latelang oa phekolo o tšoana le oa mohato o le mong.
