Noma yikuphi ukuvuza okungaphandle kwencazelo yephampu noma yomhlinzeki wesivalo kufanele kuhlolwe.

Ingabe ukugijima okomile kungalimaza uphawu lomshini wepompo ye-centrifugal?

Yebo. Ukugijima okomile kususa ifilimu yokugcoba phakathi kobuso besivalo, okubangela ukwakheka kokushisa okusheshayo, ukuqhekeka kobuso, umonakalo we-elastomer, kanye nokuvuza. Amaphampu kufanele afakwe i-primer efanele, afakwe umoya, futhi avikelwe ngezilawuli ezifanele.

Ukudlidliza kuyithinta kanjani impilo yesivalo somshini?

Ukudlidliza ngokweqile kuphazamisa iphethini yokuxhumana kobuso besivalo futhi kungalimaza izipilingi, ubuso, ama-O-rings, nama-bearings. Ngokuvamile kuhlotshaniswa nokugoba, ukungalingani, ukungalungi kahle, ama-bearings agugile, noma ukusebenza kude nendawo yokusebenza kahle kakhulu yephampu.
