1, gaggawa dakatarwa: a lokacin gwajin aikin na'urar, a lokacin daya daga cikin yanayi masu zuwa, ya kamata nan da nan gaggawa dakatarwa. Aikin dakatar da gaggawa shine danna maɓallin dakatar da motar, sa'an nan kuma yi aikin gyara bayan dakatarwa.
A, centrifugal fan ba zato ba tsammani samun karfi rawar jiki, kuma ya wuce tafiya darajar.
b, a cikin jiki akwai taɓawa scratching ko ba al'ada friction sauti.
c, duk wani bearing ko hatimi ya bayyana hayaki, ko wani bearing zafin jiki m tashi zuwa ƙararrawa darajar.
d, lokacin da matsin lamba na man fetur ya kasance ƙasa da ƙimar ƙararrawa kuma ba za a iya dawowa al'ada ba.
e, tankin ruwa matakin low, akwai wani suction yanayin.
f, shaft motsi darajar bayyana m ci gaba da girma, lokacin da ya kai ƙararrawa darajar.
2, al'ada kashewa: na'urar al'ada kashewa aiki kamar yadda aka tsara.
A, a hankali bude komai bawul (ko fitarwa bypass bawul), yayin da a hankali rufe fitarwa bawul.
B, a hankali kashe kananan shigar da gas batutuwa ƙofar zuwa 20 ~ 25 °.
c, danna maɓallin ajiye motoci, kuma lura ko akwai wani abu mai ban mamaki a lokacin dakatarwa.
D, na'urar dakatar da 5 ~ 10min bayan, ko bearing zafin jiki sauka zuwa 45 ° C za a iya dakatar da samar da man fetur. Ga na'urorin da ke da hatimi na madaidaiciya, famfo mai hatimi dole ne ya ci gaba da samar da man fetur har sai zafin jiki ya kasance ƙasa da 80 ℃.
Bayan dakatar da na'urar, ya kamata a kai a kai a cikin sa'o'i 2 zuwa 4 don motsa rotor 180 °.
Shigarwa Matters
1, da shigarwa na centrifugal fan duka na'urar, ya kamata a kai tsaye sanya a kan tushe don amfani da nau'i na oblique mats neman flat.
2, da filin taro centrifugal fan, yankan aiki surface a kan tushe ya kamata ya dace kare, ba ya kamata akwai tsaki ko aiki, lokacin da tushe aka sanya a kan tushe, aikace-aikace a cikin nau'i-nau'i slanted mats neman flat.
3, bearing wurin zama da tushe ya kamata ya kasance kusa da haɗin kai, longitudinal rashin daidaito ba ya kamata ya wuce 0.2 / 1000, da madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaidaicin madaida
4, kafin shaft shaft scraping ya kamata a farko gyara rotary shaft line da kuma shell shaft line, a lokaci guda daidaita tsakanin shaft da kuma shigar da iska da kuma tsakanin shaft da kuma shell baya panel shaft rami, don ya dace da kayan aiki fasaha takardun.
5, lokacin da shaft da shaft tile tarawa, ya kamata a duba bisa ga kayan aiki fasaha takardun. Bearing rufi da kuma shaft tile ya kamata a kiyaye 0.03 ~ 0.04 mm surplus (auna waje diamita na shaft tile da kuma ciki diamita na bearing wurin zama).
6, lokacin da fan shell tarawa, ya kamata a yi amfani da rotary shaft line a matsayin ma'auni don neman daidai shell matsayi da kuma sanya axial da radial rabo tsakanin impeller da shell shigarwa high gudun zuwa na'urar fasaha takardun da aka tsara, a lokaci guda bincika ko ƙasa ƙafa bolt ƙafa. Lokacin da ba a ƙayyade darajar rata ba kamar takardun fasaha na kayan aiki, ya kamata tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin tsakanin A lokacin daidaitawa yi kokarin rabo darajar kadan don inganta iska fan inganci.
7, lokacin da fan neman daidai, daban-daban axes na fan shaft da kuma lantarki injin shaft: radial positioning motsi bai kamata ya wuce 0.05mm, karkata bai kamata ya wuce 0.2 / 1000.
8, da madaidaiciya bearing tarawa centrifugal iska, daban-daban shafts na bearing rami a kan biyu bearing racks, za a iya jiran da rotor shigar bayan juyawa sassauci.
Hanyar gyara kuskure
centrifugal iska ne wani gini rikitarwa kayan aiki, yafi da iska shigarwa, iska bawul, impeller, inji, iska fitarwa. A cikin yanayi daban-daban, tasirin centrifugal fan ba daidai ba ne. Saboda haka, sassa daban-daban na aiki yanayi ba daidai ba ne, da kuma tasirin centrifugal fan zai shafi. Debugging centrifugal fan zuwa jihar, za a iya fara daga hanyoyi da yawa.
1, centrifugal fan ba da damar cikakken ƙarfin lantarki farawa ko saukar da ƙarfin lantarki, amma ya kamata a lura da cewa a lokacin da cikakken ƙarfin lantarki farawa yanzu ne kimanin 5-7 sau na yau da kullun, da saukar da ƙarfin lantarki farawa torque daidai da ƙarfin lantarki murabba'in, a lokacin da wutar lantarki grid damar ba ta isa, ya kamata a yi amfani da sau
2, centrifugal fan a lokacin gwajin motar, ya kamata a hankali karanta samfurin umarnin, duba ko wiring hanyar dace da wiring zane-zane; Ya kamata a duba da hankali ko aikin ƙarfin lantarki na samar da wutar lantarki na fan ya dace da buƙatun, ko samar da wutar lantarki ya bace ko lokaci guda, ko ƙarfin kayan rarraba ya dace da buƙatun.
3, lambar mutane ba kasa da mutane biyu ba a lokacin gwajin motar, mutum daya yana sarrafa samar da wutar lantarki, mutum daya yana lura da yanayin aikin fan, yana gano abubuwan da ba su da kyau don bincika lokacin dakatarwa nan da nan; Da farko duba ko juyawa shugabanci daidai; Bayan centrifugal fan fara aiki, ya kamata nan da nan duba ko kowane mataki aiki halin yanzu daidaita, ko halin yanzu ya wuce da aka ƙididdige halin yanzu; Idan akwai rashin al'ada, ya kamata a duba lokacin dakatarwa. Bayan mintuna biyar na aiki, dakatarwa bincika ko fan yana da wani al'ada, tabbatar da cewa babu wani al'ada don fara aiki.
4, lokacin da biyu gudun centrifugal injin gwaji, ya kamata fara low gudun, duba ko juyawa shugabanci ne daidai; Dole ne a fara shi a lokacin da iska ta tsaya bayan farawa, don hana juyawa mai sauri, wanda ke haifar da sauyawa da lalacewar motar.
5. Lokacin da centrifugal iska ya kai al'ada gudun juyawa, ya kamata a auna ko centrifugal iska shigarwa halin yanzu ne na al'ada, centrifugal iska aiki halin yanzu ba zai iya wuce ta Rated halin yanzu. Idan aikin halin yanzu ya wuce halin yanzu, ya kamata a bincika ko ƙarfin lantarki da aka samar ya kasance daidai.
6, da centrifugal iska da ake buƙata injin ikon yana nufin a cikin wani aiki yanayi, da centrifugal iska da kuma iska akwatin, da ake buƙata ikon a lokacin da shigar da iska bude gaba daya. Idan an buɗe iska don aiki, motar tana da haɗarin lalacewa. Lokacin da fan gwaji rufe bawul a kan fan shigo da ko fitarwa bututun, bayan aiki a hankali bude bawul, ya kai da ake bukata yanayin aiki, da kuma lura da ko fan aiki halin yanzu ya wuce da ƙididdigar halin yanzu.
Cikakken bin hanyar da aka ambata a sama don debugging centrifugal iska, zai iya ba da damar ingancin centrifugal iska ya kai sama da 98%.
