Umgomo wokuvala wokupakisha ikakhulukazi uncike kumphumela we-labyrinth kanye nomphumela wokuzala.

Umthelela we-Maze: Indawo ephansi ye-microscopic ye-shaft ayilingani kakhulu, futhi ingalingana kancane nokupakisha, kodwa ayixhumani nezinye izingxenye. Ngakho-ke, kukhona igebe elincane phakathi kokupakisha kanye ne-shaft, njenge-maze, kanti i-pressurized medium ingaphakathi kwegebe. Iphonswa izikhathi eziningana ukuze kuzuzwe umphumela wokuvala.

Ukukhipha umphumela: Kuzoba nefilimu encane ye-liquid phakathi kokupakisha kanye ne-shaft, okwenza ukupakisha kanye ne-shaft kufane nama-sliding bearings futhi idlala umphumela othile wokugcoba, ngaleyo ndlela igweme ukuguga ngokweqile kokupakisha kanye ne-shaft.

Izidingo zezinto ezibonakalayo zokupakisha: Ngenxa yezinga lokushisa, ingcindezi, kanye ne-PH yendawo evalekile, kanye nesivinini somugqa, ukugwedla kwendawo, i-coaxiality, ukuphuma kwe-radial, eccentricity nezinye izici ze-axially. icala lokuhlukanisa futha, impahla yokupakisha iyadingeka ukuze ibe nezici ezilandelayo:

1. Inezinga elithile lokunwebeka nepulasitiki

2. Ukuzinza kwamakhemikhali

3. Ukungakwazi ukungena emanzini

4. Ukuzigcoba

5. Ukumelana nezinga lokushisa

6. Kulula ukuqaqa nokuhlanganisa

7. Kulula ukwenza futhi ngentengo ephansi.

Izinto ezibonakalayo ezingenhla zithinta ngokuqondile ukusebenza kokuvala kanye nempilo yesevisi yokupakisha, futhi kunezinto ezimbalwa kakhulu ezingahlangabezana ngokugcwele nazo zonke izakhiwo ezingenhla. Ngakho-ke, ukuthola izinto zokuvala ezisezingeni eliphezulu kanye nokwenza ngcono izakhiwo zazo ezibonakalayo bekulokhu kugxile ocwaningweni emkhakheni wokubekwa uphawu.

Ukuhlukaniswa, ukwakheka kanye nokusetshenziswa kokupakisha kwe  amaphampu e-axially split case .

Ngenxa yezimo ezihlukene zokusebenza, kunezinhlobo eziningi zezinto zokupakisha. Ukuze uhlukanise kangcono futhi ukhethe ukupakisha, sivame ukuhlukanisa ukupakisha ngokusho kwempahla eyisisekelo yokubeka uphawu yokupakisha:

1. Ukupakisha i-fiber yemvelo. Ukupakisha imicu yemvelo ikakhulukazi kuhlanganisa ukotini wemvelo, ilineni, uvolo, njll. njengezinto eziyisisekelo zokuvala.

2. Ukupakisha i-mineral fiber. Ukupakishwa kwe-mineral fiber ikakhulukazi kufaka phakathi ukupakisha kwe-asbestos, njll.

3. I-synthetic fiber packing. Ukupakishwa kwe-synthetic fiber ikakhulukazi kufaka phakathi: ukupakisha kwe-graphite, ukupakisha kwe-carbon fibre, ukupakisha kwe-PTFE, ukupakisha kwe-Kevlar, ukupakisha kwe-acrylic-clip silicone fiber, njll.

4. Ukupakisha i-Ceramic ne-metal fibre Packing I-Ceramic ne-metal fiber packing ikakhulukazi ihlanganisa: ukupakisha kwe-silicon carbide, ukupakisha kwe-boron carbide, ukupakisha i-fiber yengilazi ye-alkali emaphakathi, njll. i-fiber isetshenziselwa ukwaluka ukupakisha. Njengoba kunezikhala phakathi kwemicu yokupakisha, kulula ukubangela ukuvuza. Ngasikhathi sinye, eminye imicu inezakhiwo ezingezinhle zokuzigcoba kanye ne-coefficient enkulu yokungqubuzana, ngakho-ke idinga ukugxiliswa ngama-lubricant nama-filler. kanye nezithasiselo ezikhethekile, njll. Ukwenza ngcono ukuminyana kanye nokuthambisa kwesigcwalisi, njengalokhu: amafutha amaminerali noma i-molybdenum disulfide grease exutshwe ne-graphite powder, i-talc powder, i-mica, i-glycerin, amafutha emifino, njll., kanye ne-emulsion yokuhlakazwa kwe-polytetrafluoroethylene ehlanganisiwe, kanye ku Faka amanani afanelekile ama-surfactants nama-disperants ku-emulsion. Izithasiselo ezikhethekile ngokuvamile zihlanganisa izinhlayiya ze-zinc, ama-barrier agents, i-molybdenum-based corrosion inhibitors, njll.
