Yiziphi izinzuzo zepompo lokushisa kazibuthe eliphakeme? ?

Isikhathi: 2022-12-19

  Iphampu kazibuthe enezinga eliphezulu lokushisa iwuhlobo lokudluliswa kwetorque okungathinteki kuyo ngedrayivu kazibuthe (ukuhlanganisa kazibuthe), ukuze uphawu olumile luthathe indawo yophawu oluguquguqukayo, ukuze iphampu ingavuzi ngokuphelele. Njengoba i-pump shaft kanye ne-rotor magnetic yangaphakathi ivalwe ngokuphelele ngumzimba wepompo kanye nomkhono wokuzihlukanisa, inkinga yokuvuza ixazululwe ngokuphelele, kanye nengozi yokuphepha yemidiya evuthayo, eqhumayo, enobuthi neyingozi evuza ngokusebenzisa uphawu lwepompo endaweni yokucwenga kanye namakhemikhali. imboni iyaqedwa.


Ukwakheka kwephampu

Ipompo likakazibuthe lokushisa eliphezulu liqukethe izingxenye ezintathu: impompo yokuzenzela, idrayivu kazibuthe kanye nemoto. Ingxenye eyinhloko, idrayivu kazibuthe, iqukethe i-rotor yamagnetic yangaphandle, i-rotor yamagnetic yangaphakathi kanye nomkhono wokuhlukanisa ongewona uzibuthe.

1. Ozibuthe baphakade:
Ozibuthe baphakade abenziwe ngezinto ezibonakalayo banebanga lokushisa elibanzi lokusebenza (-45-400 ° C), amandla aphoqelelayo aphezulu, i-anisotropy enhle ekuqondeni kwendawo kazibuthe, futhi akukho demagnetization ezokwenzeka lapho isigxobo esifanayo sisondelene. Iwuhlobo lomthombo omuhle kakhulu we-magnetic field.

2. Umkhono wokuzihlukanisa:
Uma kusetshenziswa i-spacer yensimbi, i-spacer isendaweni yamagnetic eshintshanayo ye-sinusoidal, futhi i-eddy current ifakwa esigabeni esincikene nendawo eya ngakulayini wamandla kazibuthe bese iguqulwa ibe ukushisa.

3. Ukulawulwa kokupholisa ukugeleza kwe-lubricant
Uma iphampu kazibuthe enezinga eliphezulu lokushisa isebenza, inani elincane loketshezi kufanele lisetshenziswe ukuze kushayelwe futhi kupholiswe indawo yeringi yeringi phakathi kwerotha kazibuthe yangaphakathi nomkhono wokuhlukanisa kanye nokubhangqa kokungqubuzana kwebhere elishelelayo. Izinga lokugeleza kwesipholile ngokuvamile lingu-2% -3% wezinga lokugeleza lokuklama kwepompo, futhi indawo yegebe yeringi phakathi kwerotha kazibuthe yangaphakathi nomkhono wokuhlukanisa ikhiqiza ukushisa okuphezulu ngenxa yama-eded currents. Lapho uketshezi olupholile lokuthambisa lungenele noma imbobo yokushaywa ingabusheleli noma ivinjiwe, izinga lokushisa lendawo eliphakathi lizoba phezulu kunokushisa okusebenzayo kukazibuthe unomphela, ukuze i-rotor yangaphakathi kazibuthe kancane kancane ilahlekelwe amandla kazibuthe futhi idrayivu kazibuthe izoba phezulu. hluleka. Lapho okuphakathi kungamanzi noma uketshezi olusekelwe emanzini, ukuphakama kwezinga lokushisa endaweni ye-annulus kungagcinwa ku-3-5 ° C; lapho okuphakathi kuyi-hydrocarbon noma uwoyela, ukukhuphuka kwezinga lokushisa endaweni ye-annulus kungagcinwa ku-5-8 ° C.

4. Ukuzala okungenalutho
Izinto ezisetshenziswayo zamabheringi ezishelelayo wepompo kazibuthe zifaka i-graphite egxilile, i-PTFE egcwele, izitsha zobumba zobunjiniyela, njll. Ngenxa yokuthi izitsha zobumba zobunjiniyela zinokumelana nokushisa okuhle, ukumelana nokugqwala, nokumelana nokungqubuzana, ama-bheriding amaphampu kazibuthe enziwa kakhulu ngezitsha zobumba zobunjiniyela.
Njengoba i-ceramics yobunjiniyela i-brittle kakhulu futhi ine-coefficient encane yokwandisa, imvume yokuthwala akumele ibe yincane kakhulu ukugwema izingozi zokubamba i-shaft.Njengoba ama-sliding bearings amaphampu kazibuthe okushisa aphezulu agcotshwa yi-medium ethuthwayo, izinto ezahlukene kufanele zisetshenziselwe yenza ama-bearings ngokuya ngemidiya ehlukene kanye nezimo zokusebenza.
