Zeziphi iingenelo zempompo yemagnethi yobushushu obuphezulu? ?

  Ipompo yemagnethi yobushushu obuphezulu luhlobo lokuhanjiswa kwetorque engadibananga nge-magnetic drive (i-magnetic coupling), ukuze isitywina esimileyo sithathe indawo yesitywina esiguquguqukayo, ukuze impompo ivuze ngokupheleleyo. Ekubeni i-pump shaft kunye ne-rotor yangaphakathi yamagnetic ivalwe ngokupheleleyo ngumzimba wempompo kunye nomkhono wokuzihlukanisa, ingxaki yokuvuza ixazululwe ngokupheleleyo, kwaye ingozi yokhuseleko lweendaba ezinokutsha, eziqhumayo, ezinobuthi kunye neziyingozi ezivuza ngokutywinwa kwempompo kwishishini lokucoca kunye neekhemikhali kupheliswa.

Ukuqulunqwa kwempompo

Ipompo yemagnethi yobushushu obuphezulu inamacandelo amathathu: impompo yokuzenzela, i-magnetic drive kunye ne-motor. Icandelo eliphambili, i-magnetic drive, liqukethe i-rotor yangaphandle yamagnetic, i-rotor yangaphakathi yamagnetic kunye ne-non-magnetic isolation sleeve.

1. Iimagnethi ezisisigxina:
Iimagnethi ezisisigxina ezenziwe ngezinto eziphathekayo zineqondo lokushisa elibanzi (-45-400 ° C), amandla anyanzeliswayo aphezulu, i-anisotropy efanelekileyo kwicala lommandla wamagnetic, kwaye akukho demagnetization iya kwenzeka xa isibonda esifanayo sisondele komnye nomnye. Luhlobo lomthombo olunge kakhulu wemagnethi.

2. Umkhono wokuzahlula:
Xa i-spacer yesinyithi isetyenziswa, i-spacer ikwindawo yemagnethi etshintshanayo ye-sinusoidal, kwaye i-eddy current inyanzelwa kwicandelo elijongene necala lomgca wamandla omagnetic kwaye iguqulwe ibe bubushushu.

3. Ukulawulwa kokupholisa ukuhamba kwe-lubricant
Xa impompo yemagnethi yobushushu obuphezulu isebenza, ulwelo oluncinci kufuneka lusetyenziselwe ukugungxula kunye nokupholisa indawo yesikhewu sesangqa phakathi kwerotha yangaphakathi yemagnethi kunye nomkhono wokwahlula kunye neperi yokukhuhlana kwebheringi etyibilikayo. Isantya sokuhamba kwesipholisi sikholisa ukuba yi-2% -3% yoyilo lokuhamba kwempompo, kunye nendawo ye-gap ye-ring phakathi kwe-rotor yangaphakathi yamagnetic kunye nomkhono wokuzihlukanisa uvelisa ubushushu obuphezulu ngenxa ye-eddy currents. Xa ulwelo lokuthambisa olupholileyo lungonelanga okanye umngxuma wokugungxula ungagudi okanye uvalwe, ubushushu bendawo ephakathi buya kuba phezulu kunobushushu obusebenzayo bemagnethi esisigxina, ukuze i-rotor yangaphakathi yamagnetic ilahlekelwe kancinci kancinci kwaye i-magnetic drive iya kusilela. Xa i-medium ingamanzi okanye i-fluid-based fluid, ukunyuka kweqondo lokushisa kwindawo ye-annulus kunokugcinwa kwi-3-5 ° C; xa i-medium i-hydrocarbon okanye i-oyile, ukunyuka kweqondo lokushisa kwindawo ye-annulus kunokugcinwa kwi-5-8 ° C.

4. Ukuthwala okucacileyo
Izinto zeempompo zemagnethi ezityibilikayo iibheringi ziquka igraphite efakiweyo, i-PTFE egcweleyo, iiseramikhi zobunjineli, njl.njl. Ngenxa yokuba iiseramikhi zobunjineli zinokuxhathisa ubushushu obulungileyo, ukuxhathisa kokutya, kunye nokumelana nokukhuhlana, iibheringi ezityibilikayo zeempompo zemagnethi zenziwe ikakhulu ngobunjineli beseramikhi.
Ekubeni i-ceramics yobunjineli i-brittle kakhulu kwaye ine-coefficient encinci yokwandisa, ukunyanzeliswa kwesigxina akufanele kube kuncinci kakhulu ukuphepha iingozi zokubamba i-shaft.Njengoko ii-sliding bearings zeempompo zemagneti ezishushu ezishushu zithanjiswa yi-medium yothutho, izinto ezahlukeneyo kufuneka zisetyenziswe ukwenza iibheringi ngokuhambelana neendaba ezahlukeneyo kunye neemeko zokusebenza.
