I. Imikhawulo Eyisisekelo Ye-Thrust Ball Bearings Ezindaweni Zasemanzini
1. Izinto ezibonakalayo:
Ama-ordinary thrust ball bearings iningi lawo enziwe nge-carbon steel (njenge-GCr15), ejwayele ukugqwala emanzini. Idatha yokuhlola ibonisa ukuthi ama-carbon steel bearings angagqwala afika ku-60% wendawo yawo ngemuva kokucwiliswa emanzini ahlanzekile izinsuku ezingu-30 (bona ucwaningo lwango-2021 kokuthi Mechanical Engineering Materials). Uma kudingekile ukuvinjelwa kwamanzi, insimbi engagqwali (efana no-440C) noma i-ceramic kufanele isetshenziswe esikhundleni salokho.
2. Ukuhluleka Kokugcoba:
Ukugcotshwa kwamafutha endabuko kuzokhukhulwa noma kufakwe emulsified lapho kuvezwe emanzini. Isibonelo, i-friction coefficient yebheringi egcotshwe nge-lithium{1}}amafutha asekelwe inyuka ngo-300% phakathi namahora angu-24 ngemva kokucwiliswa emanzini (umthombo wedatha: SKF Technical Manual). Ngokusetshenziswa ngaphansi kwamanzi, amafutha angangeni manzi (afana ne-polyurea{5}amafutha asekelwe) kufanele akhethwe noma kushintshwe okokugcoba okuqinile.
3. Ukuvala uphawu:
Ama-standard thrust bearings awanazo izimpawu, okuvumela amanzi ukuthi angene ngqo emigwaqweni yomjaho. Ukuhlolwa kubonisa ukuthi ngemva kokusebenza emanzini ngesilinganiso sokugeleza kwe-1 m / s amahora angu-10, izinga lokungena kwamanzi langaphakathi lama-bearings avulekile lidlula i-90%.

II. Izixazululo Ezingenzeka Zokusebenzisa Ngaphansi Kwamanzi
1. Ama-Bearings Akhethekile Angangeni Manzi:
- Ukuthuthukiswa Kwezinto Ezibalulekile: Isibonelo, i-NSK "Aqua Series" yase-Japan isebenzisa i-SUS304 insimbi engagqwali futhi ayibonisi ukugqwala ngemva kokuhlolwa kwesifutho sikasawoti samahora angu-500.
- Ukuthuthukiswa Kokuvalwa:-izivalo zenjoloba yezindebe eziphindwe kabili (ezenziwe nge-NBR) zingavimba umswakama ongu-99% (oqinisekiswe ngokuya nge-ISO 281).
2. Izinyathelo Zokuvikela Ezingeziwe:
- Ikhava Yokuvala Kwangaphandle: Ukwengeza indlu enesilinganiso se-IP68 kunyusa izindleko cishe ngo-20%, kodwa kwandisa ubude bempilo izikhathi ezintathu.
- Ukunakekela Okuvamile: Igrisi kufanele ishintshwe njalo ngamahora okusebenza angu-500 (kunconywa uchungechunge lwe-Klüber's Aquatro 2).
III. Izincomo Zokusebenza Ezisebenzayo
- Okwesikhathi esifushane-semisebenzi yangaphansi kwamanzi: Amabheringi avamile ane-coating yesikhashana engangeni manzi (njengesifutho se-WD-40) angamelana ngaphansi kwamahora angu-48.
Ngokusetshenziswa-isikhathi eside ngaphansi kwamanzi: Ama-Bearings aklanyelwe ngokuqondile amamotho angaphansi kwamanzi (njenge-THK's DSA series) abalulekile. Lokhu kubiza cishe u-$80-$150 lilinye kodwa kunikeza impilo yokuklama yamahora angu-50,000.
Isiphetho: Ukuthi ama-thrust ball bearings angasetshenziswa ngaphansi kwamanzi kuncike ezingeni lawo lokuvikela kanye nempilo yokusebenza. Abasebenzisi kufanele balinganisele izindleko nokusebenza, babeke phambili{1}}amamodeli avaliwe, angangeni amanzi.
