Annotatsiya: Ushbu maqolada markazdan qochma nasoslarda uchraydigan
asosiy gidravlik, mexanik va ekspluatatsion muammolar tizimli ravishda tahlil qilinadi.
Kavitatsiya, radial kuchlarning ortishi, tebranish, podshipnik va mexanik muhrlarning
nosozlanishi, bosim hamda unumdorlikning pasayishi singari holatlar nasosning
ishonchliligi va energiya samaradorligiga sezilarli ta’sir ko‘rsatadi. Tadqiqotda analitik
yondashuv, nasos xarakteristikalarini solishtirish va amaliy diagnostika belgilarini
umumlashtirish usullaridan foydalanildi. Natijada markazdan qochma nasoslar uchun
muammo-zanjir modeli taklif qilinib, nosozliklarni erta aniqlash, optimal ish rejimini
saqlash va texnik xizmat ko‘rsatishni takomillashtirish bo‘yicha tavsiyalar ishlab
chiqildi. Maqola natijalari sanoat, kommunal va qishloq xo‘jaligi nasos stansiyalarida
ekspluatatsion ishonchlilikni oshirishga xizmat qiladi.
