Kushanda musimboti wemagineti pombi

Nguva: 2021-05-11 Hits: 8

Iyo magnetic pombi inoumbwa nezvikamu zvitatu: pombi, yemagineti drive, uye mota. Chinhu chakakosha cheiyo magnetic drive ine yekunze magnetic rotor, yemukati yemagineti rotor uye isina-magineti yekuzviparadzanisa sleeve. Kana mota ichityaira yekunze magnetic rotor kuti itenderedze, iyo magnetic field inogona kupinda mukati memhepo uye isina-magineti zvinhu, uye kutyaira yemukati yemagineti rotor yakabatana kune iyo impeller kutenderera zvakafanana, nekuziva kusabatana kwekutapurirana kwesimba, uye shandura iyo inesimba chisimbiso muchisimbiso chakamira. Nekuti iyo pombi mugodhi nemukati wemagineti rotor akanyatsovharirwa nemuviri wepombi uye ruoko rwekuzviparadzanisa, dambudziko re "kumhanya, kuburitsa, kudonhedza, uye leakage" rakagadziriswa zvachose, uye leakage remoto unopisa, unoputika, une chepfu uye unokuvadza midhiya mukati. iyo yekunatsa uye kemikari indasitiri kuburikidza nepombi chisimbiso inobviswa. Iyo ingangoita njodzi dzekuchengetedza zvinobudirira kuona hutano hwepanyama uye hwepfungwa uye kugadzirwa kwakachengeteka kwevashandi.

1. Kushanda musimboti wemagineti pombi
N mapaundi emagineti (n iri kunyange nhamba nhamba) akaunganidzwa mukati nekunze magnetic rotors emagineti actuator muhurongwa hwenguva dzose, kuitira kuti magineti zvikamu zviite zvakakwana zvakabatana magineti system pamwe neayo. Kana matanda emukati neyekunze ari pakatarisana, ndiko kuti, kona yekufambisa pakati pematanda maviri emagetsi Φ = 0, iyo simba remagineti remagineti ndiyo yakaderera pane ino nguva; kana iwo magineti matanda akatenderera kuenda padanda rimwe chete, iyo yekumisidzana kona pakati pemagineti matanda maviri Φ = 2π / n, iro simba remagineti remagineti system rakanyanya panguva ino. Mushure mekubvisa simba rekunze, sezvo iwo magineti matanda eiyo magineti system achidzokerana, iro simba remagineti rinodzosera magineti kune rakaderera simba remagineti nyika. Ipapo magineti anofamba, achifambisa iyo magnetic rotor kutenderera.

2. Maumbirwo ezvimiro
1. Permanent magineti
Permanent magineti akagadzirwa neasingawanzo epasi zvachose magineti zvinhu zvine hupamhi hwekushanda tembiricha renji (-45-400 ° C), kukwirira kwekumanikidza, uye yakanaka anisotropy munzira yeiyo magnetic field. Demagnetization haizoitika kana iwo mamwe matanda ave pedyo. Iyo yakanaka sosi yemagineti munda.
2. Isleeve ruoko
Kana simbi inopatsanura sleeve ichishandiswa, ruoko rwekuzviparadzanisa rwuri musinusoidal alternating magnetic field, uye eddy yazvino inofambiswa muchikamu chemuchinjikwa chakanangana nekutungamira kwemagineti esimbi mutsara uye ikashandurwa kuita kupisa. Izwi re eddy razvino nderekuti: iko Pe-eddy ikozvino; K-chinogara; n-rated kumhanya kwepombi; T-rinobva hutachiwana torque; F-kumanikidza mune iyo spacer; D-yemukati dhayamita yeiyo spacer; kudzvinyirira kwechinhu; Kana pombi yagadzirwa, n naT zvinopihwa nemamiriro ekushanda. Kuderedza eddy yazvino kunogona kungotariswa kubva pazvinhu zveF, D, zvichingodaro. Ruoko rwekuzviparadzanisa rwakagadzirwa nemidziyo isiri yesimbi ine masimba ekudzivirira uye simba rakakwira, iro rinoshanda kwazvo mukuderedza eddy yazvino.

3. Kudzora kwekutonhora kwemafuta ekuyerera
Kana iyo pombi yemagineti iri kumhanya, shoma shoma yemvura inofanirwa kushandiswa kugeza uye kutonhodza iyo annular gap nzvimbo pakati peyemukati magineti rotor uye yakasarudzika sleeve uye yekukwesana peya yekutsvedza inotakura. Kuyerera kweye inotonhorera inowanzo kuve 2% -3% yeiyo dhizaini kuyerera chiyero chepombi. Iyo annulus nharaunda iri pakati peyemukati magineti rotor uye yakasarudzika sleeve inogadzira yakanyanya kupisa nekuda kweeddy mafungu. Kana girizi inotonhorera isingakwani kana gomba rinodzika risingatsvedzerere kana kuvharika, tembiricha yepakati ichave yakakwira kupfuura tembiricha yekushanda yemagineti anogara aripo, uye iyo yemukati magineti rotor zvishoma nezvishoma inorasikirwa nemagineti uye iyo magnetic drive inotadza. Kana iyo svikiro iri mvura kana mvura-yakavakirwa mvura, iyo tembiricha inokwira munzvimbo yekudzima inogona kuchengetwa pa 3-5 ° C; kana iyo yepakati iri hydrocarbon kana mafuta, iyo tembiricha inokwira munzvimbo yekudzima inogona kuchengetwa pa5-8 ° C.

4. zvishoma nezvishoma mumatope inobereka
Izvo zvinoshandiswa zvekutsvedza mabheyamu emagineti mapombi akaiswa enhumbu grafiti, izere ne polytetrafluoroethylene, mainjiniya keramiki uye zvichingodaro. Nekuti mainjiniya ceramics ane akanaka kupisa kuramba, ngura kuramba, uye kukweshera kuramba, iwo anotsvedza mabhegi emagetsi magineti anowanzo kuve akagadzirwa enjiniya keramiki. Nekuti mainjiniya maceramics akapwanyika chaizvo uye ane diki yekuwedzera coefficient, iyo yekutakura clearance haifanire kunge iri diki kudzivisa shaft yakaturikwa tsaona.
Sezvo iyo inotsvedza inotakura yemagineti pombi yakakwenenzverwa neyakaendeswa svikiro, zvakasiyana zvinhu zvinofanirwa kushandiswa kugadzira mabheyari maererano akasiyana midhiya uye mashandiro ezvinhu.

5. Matanho ekudzivirira
Kana chikamu chinotyairwa chemagineti chinotyaira chiri kuwanda kana iro rotori rakanamatira, nzvimbo huru uye dzinofambiswa dzemagineti drive dzinobva dzatsvedza kuti dzidzivirire pombi. Panguva ino, iyo yekupedzisira magineti pane yemagineti actuator ichagadzira eddy kurasikirwa uye nemagineti kurasikirwa pasi pechiito cheiyo inotsiva magineti yeanoshanda rotor, zvinozoita kuti tembiricha yeinogara magineti kusimuka uye iyo magnetic actuator kutsvedza uye kutadza .
Tatu, zvakanakira magineti pombi
Inofananidzwa nemapombi epentrifugal anoshandisa michini zvisimbiso kana kurongedza zvisimbiso, magineti mapombi ane zvinotevera zvinotevera.
1. Iyo pombi shaft inochinja kubva pane ine simba chisimbiso ichienda kune yakavharwa static chisimbiso, ichidzivirira zvachose kuerera kwepakati.
2. Iko hakuna kudikanwa kwekuzvimiririra girizi uye kutonhora mvura, izvo zvinoderedza kushandiswa kwesimba.
3. Kubva pakubatanidza kuendesa kune synchronous dhonza, hapana kusangana uye kukweshera. Iyo ine yakaderera simba rekushandisa, yakanyanya kushanda, uye ine damping uye vibration kudzikisira mhedzisiro, iyo inoderedza kukanganisa kwe mota kudedera pane iyo magnetic pombi uye kukanganisa kune mota kana iyo pombi ikaitika yecavitation vibration.
4. Kana yawandisa, iyo yemukati neyekunze magineti rotors anotsvedza zvishoma, izvo zvinodzivirira mota nepombi.
Chechina, mashandiro ekuchengetedza
1. Dzivirira zvimedu kupinda
(1) Kusviba kweFerromagnetic uye zvidimbu hazvibvumirwe kupinda mune yemagineti pombi yekutyaira uye kutakura kukakavara vaviri.
(2) Mushure mekutakura iyo svikiro iri nyore kusimbisa kana kukanda, isa mvura mukati menguva (dururira mvura yakachena mupombi mhiri mushure mekumisa pombi, uye idurure mushure me1 min yekushanda) kuve nechokwadi chehupenyu hwebasa rekutsvedza .
(3) Kana uchitakura iyo svikiro ine yakasimba solid, inofanirwa kusefetwa panopinda pombi kuyerera pombi.
2. Dzivirira demagnetization
(1) Iyo magnetic pombi torque haigone kugadzirwa yakanyanya kudiki.
(2) Inofanirwa kuvhiyiwa pasi pemamiriro ekushisa akatsanangurwa, uye iyo tembiricha yepakati inorambidzwa zvakanyanya kubva pachiyero. Iyo platinamu yekudzivirira tembiricha sensor inogona kuiswa pane yekunze nzvimbo yemagineti pombi yekuzviparadzanisa sleeve kuti uone kukwira kwekushisa munzvimbo yekudzima, kuti igone kurira kana kudzima kana tembiricha ichidarika muganho.
3. Dzivirira kukakavara kwakaoma
(1) Idling inorambidzwa zvachose.
(2) Izvo zvakarambidzwa zvachose kubvisa iyo svikiro.
(3) Iine vharuvhu yekubuda yakavharwa, iyo pombi haifanire kuramba ichimhanya kweanopfuura maminetsi maviri kudzivirira iyo magnetic actuator kubva pakupisa uye kutadza.
