Nzira yekugadzirisa sei dambudziko rerombo mafuta kudzoka kweiyo screw chiller?

Pane nzira mbiri dzekudzorera mafuta ku compressor, imwe ndeye kudzoka kwemafuta kweanopatsanura mafuta, uye imwe yacho kudzoka kwemafuta kwepombi yekudzosa mweya. Iyo yekuparadzanisa oiri yakaiswa pane iyo compressor yekuzadza pombi. Kazhinji, 50-95% yemafuta inogona kupatsanurwa. Iyo yekudzosa mafuta mhedzisiro yakanaka, kumhanya kuri kukurumidza, uye huwandu hwemafuta hunopinda muipi pombi hwaderedzwa zvakanyanya, nokudaro zvichitambanudzira basa pasina mafuta kudzoka. nguva.

Hazvina kujairika kune inotonhorera yekuchengetedza mafiriji masisitimu ane akareba zvakanyanya mapaipi, akazara-emvura echando-kugadzira masystem, uye chando-kuomesa michina ine yakadzika kwazvo tembiricha kudzoka anopfuura maminetsi gumi kana kunyange gumi nemaviri maminetsi mushure mekutanga kumusoro, kana neakanyanya mashoma mafuta anodzoka. Dhizaini Sisitimu yakashata inokonzeresa kuti compressor imire nekuda kwekumanikidza kwemafuta. Kuisirwa kwepamusoro-kunyatsoshanda mafuta eparadzanisa mufiriji system kunogona kuwedzera zvakanyanya iyo compressor isiri-yekudzoka mashandiro nguva, kuitira kuti iyo compressor inogona kupfuura nhanho nhanho yekusave nemafuta ekudzoka mushure mekutanga-kumusoro. .

Mafuta ekuzora asina kupatsanurwa anopinda muchirongwa uye kuyerera neiyo firiji iri mupombi kuti itange kutenderera kwemafuta. Mushure mekunge mafuta ekuzora apinda mu evaporator, chikamu chemafuta ekuzora anopatsanurwa kubva kune firiji nekuda kwetembiricha yakaderera uye kusanyungudika kwakadzika; kune rimwe divi, yakadzika tembiricha uye yakakwira viscosity, iyo yakaparadzaniswa mafuta ekuzora iri nyore kutevedzera kumadziro emukati wepombi, uye zvinonetsa kuyerera. Iyo yakadzika iyo tembiricha yemvura, zvakanyanya kuomarara kudzosa mafuta. Izvi zvinoda kuti dhizaini uye kuvakwa kwepombi yekushanduka kwemvura uye pombi yekudzoka inofanira kuve inodzosera mafuta. Tsika yakajairika ndeyekutora inoderera dhizaini dhizaini uye nekuona yakakura mweya kuyerera velocity.

Kune mafirita masisitimu ane akanyanya kutonhora tembiricha, pamusoro pekushandisa yakanyanya-inoshanda mafuta akaparadzanisa, akasarudzika solvents anowanzo kuwedzerwa kudzivirira mafuta ekuzadza kubva kuvharira ma capillari uye ekuwedzera mavharuvhu, uye kubatsira kudzosa mafuta. Panguva imwecheteyo, vamwe vanhu vanoshandisa iyo yakavakirwa-mukati mukati memhepo yekuisa mweya kutsiva iyo yekunze mafuta. Pamusoro, inochengetedza mutengo, asi maererano nemutengo wekushandisa wenguva refu, inozongowedzera chete mutengo wekushandisa. Iko kushanda kweiyo system kucharamba kuchikura uye kuwedzera.

Mukushandisa kunoshanda, matambudziko ekudzoka kwemafuta anokonzerwa nekugadzirwa kwakashata kweiyo evaporator uye yekudzosa mutsara haina kujairika. Kune maR22 neR404A masystem, kudzoserwa kwemafuta evaporator mafashama kwakanyanya kuomarara, uye dhizaini yekudzora mafuta pombi sisitimu inofanirwa kuve yakangwarira. Kune yakadaro sisitimu, kushandiswa kwemafuta epamusoro-soro kunogona kudzora huwandu hwemafuta achipinda mupombi, uye nekuwedzera nguva isiri-yekudzoka yemapaipi ekudzosera mweya mushure mekutanga.

Kana iyo compressor yakakwira kupfuura iyo evaporator, iyo mafuta yekudzosa bend pane yakatwasuka yekudzoka pombi inodikanwa. Iyo bend yekudzoka inofanirwa kunge iine compact sezvinobvira kudzikisa kuchengetera kwemafuta. Iyo nzvimbo pakati peoiri yekudzosa mafuta inokodzera. Kana huwandu hwekudzoserwa kwemafuta hwakati kurei, mamwe mafuta ekuzora anofanirwa kuwedzerwa. Mutsara wekudzosa mafuta weiyo musiyano mutoro system inofanirawo kungwarira. Kana mutoro wacho waderedzwa, mhepo yekumhanyisa yekumhanyisa inoderera, yakanyanya kumhanya mhanyisa haina kukodzera kudzoka kwemafuta. Kuti uve nechokwadi chekudzoka kwemafuta pasi pemutoro wakadzika, iyo yekumira yekukweva pombi inogona kutora miviri yakatwasuka mapaipi.

Zvakare, kazhinji compressor kutanga hakubatsire kudzoka kwemafuta. Sezvo iyo compressor inomira kwenguva pfupi inoenderera yekushanda nguva, hapana nguva yekuumba yakatsiga-inomhanya mweya kuyerera mune yekudzosera pombi, uye mafuta ekuzora anogona kungogara mupombi. Kana kudzoka kwemafuta kuri kushoma pane mafuta eBen, iyo compressor ichave ishoma nemafuta. Iyo ipfupi iyo nguva yekushanda, iyo yakareba iyo pombi uye iyo inowedzera kuomesa system, iyo inonyanya kuratidza dambudziko rekudzoka kwemafuta. Naizvozvo, kazhinji, usatanga iyo compressor kazhinji.

Muchidimbu, kushayikwa kwemafuta kunokonzeresa kushomeka kwekukanganisa. Mhedzisiro yekushaikwa kwemafuta haisi iyo huwandu uye kumhanya kweiyo screw-mhando chiller, asi hurombo mafuta kudzoka kweiyo system. Kuisirwa kwepamusoro-kunyatsoshanda mafuta eparadzanisa kunogona kukurumidza kudzosa mafuta uye kuwedzera nguva yekushanda kwecompressor pasina mafuta kudzoka. Dhizaini yeiyo evaporator uye iyo yekudzosera gomba pombi inofanira kutora kudzoserwa kwemafuta mukufunga. Matanho ekuchengetedza akadai sekudzivirira kutanga kazhinji, kudzora nguva, kuzadzikisa nguva firiji, uye kumisikidza nenguva yekupfeka zvikamu (zvakaita semabheyari) zvinobatsirawo kudzoka kwemafuta
