1. Ukugoba noma ukungahambi kahle kwe-shaft yepompo yamanzi kuzobangela ukuba iphampu yamanzi inyakaze futhi kubangele ukushisa noma ukuguga kwe-bearing.

2. Ngenxa yokwanda kwe-axial thrust (isibonelo, lapho i-disc yebhalansi kanye nendandatho yebhalansi empompini yamanzi igugile kakhulu), umthwalo we-axial ekuthwaleni uyanda, okwenza ukuthi ukuthwala ukushisa noma konakaliswe. .

3. Inani lamafutha okugcoba (amafutha) ku-bearing alanele noma lidlulele, izinga liphansi, futhi kukhona imfucumfucu, izikhonkwane zensimbi nezinye imfucumfucu: I-sliding bear ngezinye izikhathi ayijikelezi ngenxa yokulimala kwamafutha, futhi ukuthwala akukwazi ukungeniswa emafutheni ukuze kubangele ukushisa.

4. Imvume yokufanisa ayihlangabezani nezidingo. Isibonelo, uma ukufanisa phakathi kweringi yangaphakathi ethwele kanye ne-shaft yepompo yamanzi, iringi yangaphandle ethwele kanye nomzimba othwalayo kuxege kakhulu noma kuqine kakhulu, kungabangela ukuthwala ukushisa.

5. Ibhalansi emile ye-rotor yepompo yamanzi ayilungile. Amandla e-radial we-rotor yepompo yamanzi ayanda futhi umthwalo wokuthwala uyanda, okubangela ukushisa ukushisa.

6. Ukudlidliza kwephampu yamanzi lapho isebenza ngaphansi kwezimo zephoyinti elingadizayinelwe nakho kuzobangela ukushisa kwephampu yamanzi.

7. Ukuthwala kuye konakaliswa, okuvame ukuba yimbangela evamile yokushisa okuthwala. Isibonelo, i-roller bearing engaguquki ihlala yonakalisiwe, ibhola lensimbi lichoboza indandatho yangaphakathi noma ukuphuka kwendandatho yangaphandle; ungqimba lwe-alloy lwe-bearing bearing luyaxebuka futhi liwe. Kulesi simo, umsindo ekuthwaleni awujwayelekile futhi umsindo uphezulu, ngakho-ke ukuthwala kufanele kuhlakazwe ukuze kuhlolwe futhi kushintshwe ngesikhathi.

Izinyathelo zokuzivikela ngokumelene nezinga lokushisa eliphakeme kakhulu lephampu yamanzi:

1. Naka ikhwalithi yokufaka.
2. Qinisa isondlo.
3. Ama-bearings kufanele akhethwe ngokusho kwedatha efanele.
