Li-compressor ke karolo ea bohlokoa ea hoo e batlang e le setsi se seng le se seng sa tlhahiso. Ka tloaelo ho thoe ke pelo ea tsamaiso efe kapa efe ea moea kapa ea khase, thepa ena e hloka tlhokomelo e khethehileng, haholo-holo ho tlotsoa ha eona. Ho utloisisa karolo ea bohlokoa eo lubrication e e bapalang ho li-compressor, u tlameha ho qala ka ho utloisisa ts'ebetso ea tsona hammoho le litlamorao tsa sistimi ho lubricant, e lokelang ho khethoa ke lubricant le hore na liteko tsa tlhahlobo ea oli li lokela ho etsoa joang.
● Mefuta ea Compressor le Mesebetsi
Mefuta e mengata e fapaneng ea li-compressor e fumaneha, empa karolo ea bona ea mantlha e batla e tšoana kamehla. Li-compressor li etselitsoe ho matlafatsa khatello ea khase ka ho fokotsa molumo oa eona ka kakaretso. Ka mantsoe a bonolo, motho a ka nahana ka compressor e le pompo e kang ea khase. Ts'ebetso e hlile e ts'oana, phapang e kholo ke hore compressor e fokotsa molumo mme e tsamaisa khase ka sistimi, ha pompo e hatella le ho tsamaisa metsi ka sistimi.
Li-compressor li ka aroloa ka mekhahlelo e 'meli e akaretsang: phalliso e ntle le e matla. Li-compressor tsa Rotary, diaphragm le tse khutlisetsang li oela tlas'a sehlopha sa phalliso e ntle. Li-compressor tsa rotary li sebetsa ka ho qobella likhase libakeng tse nyane ka li-screw, lobes kapa li-vanes, ha li-compressor tsa diaphragm li sebetsa ka ho hatella khase ka ho tsamaea ha lera. Li-compressor tse khutlisang li hatella khase ka piston kapa letoto la lipiston tse khannoang ke crankshaft.
Li-centrifugal, phallo e tsoakiloeng le li-axial compressors li sehlopheng se matla. Compressor ea centrifugal e sebetsa ka ho hatella khase e sebelisa disk e potolohang ntlong e entsoeng. Compressor e nang le phallo e tsoakiloeng e sebetsa joalo ka konpresser ea centrifugal empa li-drive li phalla ka axially ho fapana le radially. Li-compressor tsa Axial li theha khatello ka letoto la lifola tsa moea.
● Liphello ho Litlolo
Pele ho khetho ea setlolo sa compressor, e 'ngoe ea lintlha tsa mantlha tse lokelang ho nahanoa ke mofuta oa khatello eo lubricant e ka bang le eona ha u le ts'ebeletso. Ka tloaelo, likhatello tsa lubricant ka har'a li-compressor li kenyelletsa mongobo, mocheso o feteletseng, khase e hatelletsoeng le moea, likaroloana tsa tšepe, ho qhibiliha ha khase le libaka tse chesang tse tsoang.
Hopola hore ha khase e hatelloa, e ka ba le liphello tse mpe ho lubricant 'me ea fella ka ho fokotseha ho hlokomelehang ha viscosity hammoho le mouoane, oxidation, carbon depositing le condensation ho tloha ho bokella mongobo.
Hang ha u se u hlokometse ka lintho tse ka sehloohong tse amehang tse ka hlahisoang ho lubricant, u ka sebelisa tlhahisoleseding ena ho fokotsa khetho ea hau bakeng sa setlolo se loketseng sa compressor. Litšobotsi tsa lubricant e matla ea mokhethoa li tla kenyelletsa botsitso bo botle ba oxidation, anti-wear le corrosion inhibitor additives, le thepa ea demulsibility. Li-stocks tsa maiketsetso li ka boela tsa sebetsa betere maemong a pharaletseng a mocheso.
● Khetho ea Mafura
Ho etsa bonnete ba hore o na le lubricant e nepahetseng ho tla ba bohlokoa bophelong ba compressor. Mohato oa pele ke ho bua ka likhothaletso tse tsoang ho moetsi oa lisebelisoa tsa mantlha (OEM). Compressor lubricant viscosities le likarolo tse ka hare tse tlotsoang li ka fapana haholo ho latela mofuta oa compressor. Litlhahiso tsa moetsi li ka fana ka ntlha e ntle ea ho qala.
Ka mor'a moo, nahana ka khase e hatelitsoeng, kaha e ka ama mafura haholo. Khatello ea moea e ka baka mathata ka mocheso o phahameng oa lubricant. Ligase tsa Hydrocarbon li na le ho qhaqha litlolo, 'me, ka lehlakoreng le leng, butle-butle li theola viscosity.
Likhase tse sa sebetseng ka lik'hemik'hale tse kang carbon dioxide le ammonia li ka 'na tsa sebetsana le lubricant' me tsa fokotsa viscosity hammoho le ho etsa sesepa tsamaisong. Likhase tse sebetsang ka lik'hemik'hale tse kang oksijene, chlorine, sulfur dioxide le hydrogen sulfide li ka etsa li-tacky deposits kapa tsa senya haholo ha ho le mongobo o mongata ka har'a lubricant.
U boetse u lokela ho ela hloko tikoloho eo compressor lubricant e tlas'a eona. Sena se ka kenyelletsa mocheso o potolohileng, mocheso o sebetsang, litšila tse potolohileng moea, ebang compressor e ka hare le e koahetsoeng kapa e ka ntle 'me e pepesehetse boemo bo bobe ba leholimo, hammoho le indasteri eo e sebetsang ho eona.
Hangata li-compressor li sebelisa mafura a maiketsetso ho latela khothaletso ea OEM. Hangata bahlahisi ba lisebelisoa ba hloka hore ho sebelisoe mafura a nang le letšoao e le boemo ba tiisetso. Maemong ana, u ka 'na ua batla ho ema ho fihlela ka mor'a hore nako ea tiisetso e felile ho etsa phetoho ea lubricant.
Haeba kopo ea hau hajoale e sebelisa setlolo se thehiloeng ho liminerale, ho fetohela ho sa maiketsetso ho tlameha ho utloahala, kaha hangata sena se tla bitsa chelete e ngata. Ehlile, haeba litlaleho tsa hau tsa tlhahlobo ea oli li bonts'a matšoenyeho a itseng, mafura a maiketsetso e ka ba khetho e ntle. Leha ho le joalo, etsa bonnete ba hore ha u sebetsane le matšoao a bothata feela empa ho e-na le hoo u rarolla lisosa tsa tsamaiso.
Ke lisebelisoa life tsa maiketsetso tse utloahalang haholo ts'ebetsong ea compressor? Ka tloaelo, li-polyalkylene glycols (PAGs), polyalphaolefins (POAs), tse ling tsa diester le polyolester li sebelisoa. Ke efe ho li-synthetics tsena eo u ka e khethang e tla ipapisa le lubricant eo u tlohang ho eona hammoho le ts'ebeliso.
E na le ho hanyetsa oxidation le bophelo bo bolelele, polyalphaolefins ka kakaretso ke sebaka se loketseng sa oli ea liminerale. Li-polyalkylene glycols tse se nang metsi li fana ka ho qhibiliha hantle ho thusa ho boloka li-compressor li hloekile. Li-ester tse ling li na le solubility e betere ho feta li-PAGs empa li ka loana le mongobo o feteletseng tsamaisong.

● Liteko tsa Tlhahlobo ea Oli
Liteko tse ngata li ka etsoa sampuling ea oli, kahoo ho bohlokoa ho ba hlokolosi ha u khetha liteko tsena le maqhubu a sampole. Teko e lokela ho akaretsa likarolo tse tharo tsa mantlha tsa tlhahlobo ea oli: thepa ea mokelikeli oa setlolo, boteng ba litšila ka har'a sistimi ea ho tlotsa le litšila life kapa life tse tsoang mochining.
Ho ipapisitse le mofuta oa compressor, ho ka ba le liphetoho tse nyane letlapeng la tlhahlobo, empa hangata ho tloaelehile ho bona viscosity, tlhahlobo ea mantlha, Fourier transform infrared (FTIR) spectroscopy, nomoro ea acid, bokhoni ba varnish, tlhahlobo e potolohang ea khatello ea oxidation ea sekepe (RPVOT). ) le litlhahlobo tsa ho felloa ke mokelikeli tse khothaletsoang bakeng sa ho lekola boleng ba mokelikeli oa lubricant.
Liteko tsa litšila tsa mokelikeli bakeng sa li-compressor li kanna tsa kenyelletsa ponahalo, FTIR le tlhahlobo ea mantlha, athe tlhahlobo e le 'ngoe feela e tloaelehileng e tsoang ponong ea litšila e ka ba tlhahlobo ea mantlha. Mohlala oa li-slate tsa tlhahlobo ea oli le meeli ea alamo bakeng sa li-compressor tsa centrifugal li bontšitsoe ka holimo.
Hobane liteko tse ling li ka lekola mathata a mangata, tse ling li tla hlaha ka mekhahlelo e fapaneng. Mohlala, tlhahlobo ea mantlha e ka ts'oara sekhahla sa ho fokotseha ho eketsehileng ho tsoa ponong ea thepa ea mokelikeli, athe likaroloana tsa tlhahlobo ea litšila kapa FTIR li ka supa oxidation kapa mongobo e le tšilafalo ea mokelikeli.
Meeli ea alamo hangata e beoa e le lits'ebetso tsa laboratori, 'me limela tse ngata ha li belaelle boleng ba tsona. U lokela ho hlahloba le ho netefatsa hore meeli ena e hlalositsoe ho lumellana le merero ea hau ea ho tšepahala. Ha u ntse u ntlafatsa lenaneo la hau, u ka ba ua batla ho nahana ka ho fetola meeli.

● Ho Utloisisa Compressor Lubrication
Mabapi le ho tlotsa ha tsona, li-compressor li ka bonahala li rarahane. Ha uena le sehlopha sa hau le utloisisa mosebetsi oa compressor hamolemo, litlamorao tsa sistimi ho lubricant, hore na ke lubricant efe e lokelang ho khethoa le hore na liteko tsa tlhahlobo ea oli li lokela ho etsoa joang, menyetla ea hau ea ho boloka le ho ntlafatsa bophelo ba lisebelisoa tsa hau e betere.
