Compressors chikamu chakakosha cheanenge ese ekugadzira nzvimbo. Inowanzo kunzi moyo wechero mweya kana gasi system, zvinhu izvi zvinoda kutariswa zvakanyanya, kunyanya kudzosa kwavo. Kuti unzwisise basa rakakosha rinoitwa nerubrication mumacompressor, unofanirwa kutanga wanzwisisa basa ravo pamwe nemhedzisiro yehurongwa pane lubricant, iyo lubricant yekusarudza uye kuti ndeipi bvunzo dzekuongorora mafuta dzinofanira kuitwa.
● Compressor Types uye Mabasa
Mazhinji akasiyana compressor marudzi anowanikwa, asi basa ravo rekutanga rinenge rakafanana. Macompressor akagadzirirwa kuwedzera kudzvanywa kwegasi nekudzikisa huwandu hwayo hwese. Mumashoko akareruka, munhu anogona kufunga nezve compressor sepombi yakaita segasi. Iko kushanda kwakafanana, nemusiyano mukuru uri wekuti compressor inoderedza vhoriyamu uye inofambisa gasi kuburikidza nehurongwa, nepo pombi inongomanikidza uye kutakura mvura kuburikidza nehurongwa.
Macompressors anogona kukamurwa kuita maviri akajairwa mapoka: yakanaka kusimuka uye ine simba. Rotary, diaphragm uye anodzoreredza macompressor anowira pasi peiyo yakanaka-displacement classification. Rotary compressors inoshanda nekumanikidza magasi munzvimbo diki kuburikidza ne screws, lobes kana vanes, nepo diaphragm compressor inoshanda nekumanikidza gasi kuburikidza nekufamba kwe membrane. Reciprocating compressors compresses gasi kuburikidza nepiston kana nhevedzano yepistons inofambiswa ne crankshaft.
Centrifugal, yakasanganiswa-kuyerera uye axial compressors iri muchikamu chine simba. A centrifugal compressor inoshanda nekumanikidza gasi uchishandisa dhisiki rinotenderera mune yakaumbwa imba. Iyo yakasanganiswa-inoyerera compressor inoshanda zvakafanana necentrifugal compressor asi madhiraivha anoyerera axially kwete radially. Axial compressors inogadzira compression kuburikidza nenhevedzano yeairfoils.
● Migumisiro paMafuta
Isati yasarudzwa yecompressor lubricant, chimwe chezvinhu zvekutanga zvekufunga nezvazvo imhando yekunetsa iyo lubricant inogona kuiswa pairi musevhisi. Kazhinji, lubricant stressors mumacompressors zvinosanganisira hunyoro, kupisa kwakanyanya, gasi rakadzvanywa nemhepo, zvimedu zvesimbi, kunyungudika kwegasi, uye nzvimbo dzinopisa dzinobuda.
Ramba uchifunga kuti kana gasi rikamanikidzwa, rinogona kuva nemhedzisiro yakaipa pamafuta uye zvichikonzera kuderera kunooneka kweviscosity pamwe nekubuda, oxidation, kabhoni depositing uye condensation kubva mukuunganidzwa kwemwando.
Kana iwe uchinge waziva nezve zvakakosha zvinonetsa zvinogona kuunzwa kune lubricant, unogona kushandisa ruzivo urwu kupfupisa sarudzo yako kune yakakodzera compressor lubricant. Hunhu hweakasimba mukwikwidzi lubricant zvinosanganisira yakanaka oxidation kugadzikana, anti-kupfeka uye corrosion inhibitor additives, uye demulsibility zvivakwa. Synthetic base stocks inogonawo kuita zvirinani mumatembiricha akakura.
● Lubricant Selection
Kuve nechokwadi chekuti une lubricant yakakodzera ichave yakakosha muhutano hwecompressor. Danho rekutanga nderekunongedzera kurudziro kubva kumugadziri wemidziyo yekutanga (OEM). Compressor lubricant viscosities uye zvikamu zvemukati zviri kuiswa mafuta zvinogona kusiyana zvakanyanya zvichienderana nerudzi rwe compressor. Mazano emugadziri anogona kupa pekutangira kwakanaka.
Tevere, funga nezve gasi riri kudzvanywa, sezvo rinogona kukanganisa zvakanyanya lubricant. Kudzvanywa kwemhepo kunogona kutungamirira kumatambudziko ane tembiricha yakakwira lubricant. Hydrocarbon magasi anowanzo kunyungudutsa mafuta uye, zvakare, zvishoma nezvishoma anodzikisa viscosity.
Kemikari inert magasi akadai secarbon dioxide uye ammonia anogona kuita nerubricant uye kuderedza viscosity pamwe nekugadzira sipo muhurongwa. Makemikari anoshanda magasi seokisijeni, chlorine, sulfur dioxide uye hydrogen sulfide anogona kugadzira tacky deposits kana kuita ngura zvakanyanya kana mwando wakawandisa mumafuta.
Iwe unofanirwawo kufunga nezve nharaunda iyo compressor lubricant inoiswa. Izvi zvinogona kusanganisira ambient tembiricha, kushanda tembiricha, yakapoteredza zvinosvibisa mhepo, ingave compressor iri mukati uye yakavharwa kana kunze uye kuratidzwa nemamiriro ekunze asina kunaka, pamwe chete neindasitiri iyo inoshandiswa.
Macompressor anowanzo shandisa mafuta ekugadzira anoenderana nekurudziro yeOEM. Vagadziri vezvishandiso vanowanzoda kushandiswa kwemafuta avo emhando semamiriro ewaranti. Muzviitiko izvi, ungada kumirira kusvika mushure mekunge nguva yewaranti yapera kuti uite shanduko yemafuta.
Kana chikumbiro chako parizvino chichishandisa mineral-based lubricant, kuchinjira kune yekugadzira kunofanirwa kuve nechikonzero, sezvo izvi kazhinji zvichinyanya kudhura. Ehe, kana mishumo yako yekuongorora oiri ichiratidza zvirikunetsa, mafuta ekugadzira anogona kuve sarudzo yakanaka. Zvisinei, iva nechokwadi kuti hausi kungogadzirisa zviratidzo zvechinetso asi kugadzirisa zvikonzero muhurongwa.
Ndeapi mafuta ekugadzira anoita zvakanyanya mufungo mune compressor application? Kazhinji, polyalkylene glycols (PAGs), polyalphaolefins (POAs), mamwe diesters uye polyolesters anoshandiswa. Ndeipi yeaya masynthetics yekusarudza zvinoenderana nerubricant yauri kushandura kubva pamwe nekushandisa.
Inosanganisira oxidation kuramba uye hupenyu hwakareba, polyalphaolefins kazhinji inzvimbo yakakodzera yemafuta emamineral. Non-water-soluble polyalkylene glycols inopa yakanaka solubility kubatsira kuchengeta compressors yakachena. Mamwe ma esters anotova nani solubility kupfuura maPAGs asi anogona kunetseka nehunyoro hwakanyanya muhurongwa.

Muenzaniso wemafuta ekuongorora test slates uye alarm miganhu ye centrifugal compressors.
● Oil Analysis Tests
Huwandu hwebvunzo hunogona kuitwa pamuenzaniso wemafuta, saka zvakakosha kuve yakakosha kana uchisarudza iyi bvunzo uye masampuresheni. Kuyedzwa kunofanirwa kuvhara matatu ekutanga ekuongorora oiri zvikamu: iyo lubricant's fluid zvimiro, kuvapo kwezvinosvibisa murubrication system uye chero marara kubva pamushini.
Zvichienderana nerudzi rwecompressor, panogona kuve nekugadziridzwa kudiki muyedzo slate, asi kazhinji zvakajairika kuona viscosity, elemental ongororo, Fourier shandura infrared (FTIR) spectroscopy, acid nhamba, varnish inogona, inotenderera kumanikidza mudziyo oxidation bvunzo (RPVOT). ) uye demulsibility bvunzo inokurudzirwa yekuongorora iyo lubricant's fluid zvimiro.
Fluid inosvibisa bvunzo yecompressor ingangosanganisira chitarisiko, FTIR uye yekutanga ongororo, nepo iyo chete yenguva bvunzo kubva pakupfeka kwemarara maonero kungave kwekutanga kuongorora. Muenzaniso wemafuta ekuongorora test slates uye alarm miganhu ye centrifugal compressors inoratidzwa pamusoro.
Nekuti mamwe bvunzo anogona kuongorora akawanda zvinonetsa, mamwe anozoonekwa mumapoka akasiyana. Semuyenzaniso, ongororo yekutanga inogona kubata yekuwedzera kuderera kwemazinga kubva pamvura yezvivakwa maonero, nepo zvidimbu kubva mukupfeka kwemarara kuongororwa kana FTIR inogona kuona oxidation kana mwando sechinhu chinosvibisa mvura.
Miganho yealarm kazhinji inoiswa sezvisina kurongeka nerabhoritari, uye zvidyarwa zvizhinji hazvimbobvunzi kukosha kwazvo. Iwe unofanirwa kuongorora uye kuona kuti iyi miganho inotsanangurwa kuti ienderane nezvinangwa zvako zvekuvimbika. Sezvo iwe uchigadzira chirongwa chako, ungatoda kufunga nezvekuchinja miganhu. Kazhinji, miganho yealarm inotanga yakakwira zvishoma uye inoshanduka nekufamba kwenguva nekuda kwehutsanana hwakanyanya kunangwa, kusefa uye kudzora kusvibiswa.
● Kunzwisisa Compressor Lubrication
Nezvekuzora kwavo, compressors inogona kuita seyakaoma. Izvo zvirinani iwe nechikwata chako manzwisisa basa recompressor, mhedzisiro yehurongwa pane lubricant, iyo lubricant inofanirwa kusarudzwa uye kuti ndeapi maoiri ekuongororwa bvunzo anofanirwa kuitwa, zvirinani mikana yako yekuchengetedza nekusimudzira hutano hwemidziyo yako.
