Ushbu maqolada markazdan qochma nasos ishchi g‘ildiragi diskidagi ishqalanish yo‘qotishlarini sferik sirtqi chuqurchalar yordamida kamaytirishning analitik matematik modeli ishlab chiqilgan. Tadqiqotda turbulent chegara qatlamining xususiyatlari, chuqurchalarning nisbiy chuqurligi, qoplash ulushi va Reynolds sonining o‘zaro bog‘liqligi tahlil qilingan. Model asosida chuqurchalar uchun 0,75–2,20 mm joiz chuqurlik oralig‘i aniqlangan. Eksperimental natijalar nasos foydali ish koeffitsiyenti 0,70 foiz punktiga oshganini ko‘rsatgan.Keywords
