Pfupiso ye screw compressor rotor kukanganisa ruzivo
1. Rotor zvikamu
Rotor chikamu chinoumbwa neanoshanda rotor (chirume rotor), chinotyairwa rotor (chikadzi rotor), huru kutakura, thrust bearing, bearing gland, balance piston, balance piston sleeve nezvimwe zvikamu.
2. General fault phenomena yeyin uye yang rotors
1. Normal mechanical kupfeka uye kukwegura
1.1 Kupfeka dhayamita rekunze reiyo rotor's yin uye yang giya nzira;
1.2 Kupfeka kwakajairwa kwe rotor cylinder.
2. Kukuvadzwa kwemagetsi kwakagadzirwa nemunhu
2.1 Kukwenya padhayamita rekunze reyin neyang rotor mazino;
2.2 Kukwenya pahumburumbira inotenderera;
2.3 Rutivi rwekupinza rotor uye exhaust end mavhavha anokwenywa;
2.4 Kusakara kwemabhengi ekupinza uye kupera simba uye kupera kwedenderedzwa remukati rebeche rekuvhara;
2.5 Kupfeka dhayamita yeshaft panzvimbo inotakura rotor;
2.6 Iyo shaft inoguma yeyin uye yang rotor yakakanganiswa.
3. General nhengo dzine mavanga kana kunamatira
3.1 Kukwenya nekunamira (kuvharika) pakati peYin neYang rotor;
3.2 Pakati pedhayamita rekunze rerota nemadziro emukati emuviri;
3.3 Pakati pepanoperera muromo werota nechigaro chinotakurisa mhepo;
3.4 Pakati pejenari pamucheto wekukweva werota neburi remuviri;
3.5 Pakati pejenari pamagumo ekupera kwe rotor uye gomba re shaft ye exhaust inotakura chigaro.
3. Chikonzero chekukundikana
1. Mhepo yefirita yemhepo haina kutsiviwa nenguva, zvichiita kuti mweya wakashata utore kunaka uye kusakara kwakakomba kwe rotor;kushandiswa kwakavhenganiswa kwemafuta ekuzora emhando dzakasiyana-siyana kunowanzo tungamira kusangana uye kupfeka kwe rotor;
2. Mhando yemafuta e compressor inoshandiswa haina kukodzera kana kuti haina kutsiviwa nenguva sezvinodiwa.Izvo zvisina kuchena mumafuta zvinodarika mwero, zvichikonzera mavanga pane rotor uye cylinder;
3. Kupisa kwekutsvaira kwakaderera zvikuru panguva yekushanda, zvichiita kuti unyoro mumafuta uye gasi huve hwakanyanya.Kushanda kwenguva refu kuchaita kuti mafuta aite emulsify, zvichikonzera kushanda kwenguva refu uye inlet uye kupera kwekupedzisira mabheji hakuzonyatsogadziriswa panguva yekumhanya-mhanya uye inorema-mutoro kutenderera.Kukuvadzwa kwekupisa kuchaita kuti rotor iite tambo, deform uye inonamira;
4. Deformation ye rotor drive end shaft head nekuda kwe meshing clearance ye drive coupling gear kana kutadza kwegear key connection;
5. Kukuvadzwa kusina kujairika kunokonzerwa nekutakura unhu.Kusashanda zvakanaka kwemhepo compressors kunowanzo kukonzerwa nevanhu.Mubasa rekuchengetedza zuva nezuva, chero bedzi maitiro ekushanda nekugadzirisa akanyatsoteverwa, kukundikana kwepamusoro kunogona kudziviswa zvachose.
Muchidimbu, kusveta uye kupera kwekupedzisira majenari escrew compressor rotor anotsigirwa nemabheya ari pa compressor body uye exhaust inotakura chigaro zvichiteerana.Kana iyo coaxiality ye compressor body, exhaust inotakura chigaro, uye rotor inokonzerwa nekugadziriswa kwemuchina kana kusangana, Kana izvo zvinodiwa zvekugadzira zvikasasangana, zvinotungamira kune makwara pakati pemarotor, rotor uye muviri, rotor nezvimwe. zvikamu, kana rotor inonamira.Kazhinji, iyo coaxiality inodiwa pakati pegomba re shaft uye rotor compression chamber iri mukati me 0.01 ~ 0.02mm.
Kucheneswa pakati pezvikamu mukamuri yekumanikidza ye screw compressor inowanzoyerwa muwaya kana mm.Zvikamu zviri mukamuri yekumanikidza zvinofananidzwa zvine simba.Kana iyo yakagadziriswa yemvumo yakakosha yakanyanya kudiki, yakabatana nekukanganisa mukugadzira maitiro, iyo rotor ichakurumidza kukuvara.Yakapwanyika kana yakanamatira.Mukaha uripo pakati pe rotor nemuviri unowanzo svika 0.1mm, uye gaka riri pakati peanopotera magumo erotor uye chigaro chekutakura chinopera i0.05 ~ 0.1mm.
Munguva ye disassembly process ye compressor, nekuti kubereka uye rotor shaft yakanyatsoenderana, kana simba rekuparadzanisa rakanyanya kukura, zvinokonzeresa deformation yezvikamu uye coaxiality yezvikamu pachazvo zvichaderedzwa.
Mushure mekunge compressor yaunganidzwa, zvinodikanwa kuti utarise iyo yakazara coaxiality yegungano.Kana iyo coaxiality iri kunze kwekushivirira, inokonzeresa kukwenya pakati pezvikamu kana rotor ichabatwa.
4. Njodzi uye kuonekwa kwekukuvara kwe rotor
Panguva yekushanda kwakajairika kwemhepo compressor, kana ruzha rusina kujairika, kuzunguzika kwakawedzera, tembiricha yenguva refu yekuburitsa, kana kuwandisa kwazvino kunoitika, inofanirwa kuvharwa kuti inyatso tariswa.Iwe unofanirwa kutarisa kutarisa kana iyo air compressor bearings yakakuvadzwa uye kana kuguma kwe rotor shaft yakaremara.Kana kukanganisa kwe rotor end bearing kunogona kuonekwa munguva uye muchina wacho wakavharwa pakarepo, hazvizoiti kuti kutakura kuve kunopisa uye kunamatira, uye hakuzokonzeri kukanganisa kune zvikamu zvikuru zvemagetsi.Kana kukuvadzwa kweiyo rotor kupera kusingawanikwe munguva uye iyo mhepo compressor ikashanda kwenguva yakareba, kupokana uye kutsvedza pakati peyemukati denderedzwa rekutakura uye rotor yekumisikidza inotakura chinzvimbo inowanzoitika.Muzviitiko zvakakomba, iyo rotor inotakura chinzvimbo ichava yebhuruu, yakaomeswa uye yakaonda, kana iyo rotor yekupedzisira ichaonekwa.Denderedzwa remukati rekutakura kwevhavha rakanamira, zvichiita kuti denderedzwa rekunze rekutakura ritenderere, zvichiita kuti gomba rinotakura rekuvhara kwevhavha riwedzere kana kubva kunze.Zvinogona kutoitika kuti kukuvara kwekutakura kunokonzeresa kuti rotor iparadze pasi pechiito chesimba guru, ichiparadza rotor coaxiality.
Kuongororwa kweyin uye yang rotors kunowanzoenderana nekupfeka uye kukwenya kwe rotor.Kupfeka kwayo meshing hakuzove pasi pe 0.5mm-0.7mm yezita rekuti dhayamita.Nzvimbo yekutsvaira haifaniri kuva yakakura kudarika 25mm2, kudzika hakuzove kwakakura kudarika 1.5mm, uye kwete-axiality ye rotor shaft yekupedzisira haifaniri kunge yakakura kudarika 0.010mm.
