Maqolada oqim energiyasidan foydalanadigan oqimchali nasosning sug‘orish va melioratsiya tizimidagi vertikal drenajlarning energiya samaradorligini oshirish maqsadida amaliyotda qo‘llanishi bo‘yicha o‘tkazilgan tadqiqot natijalari bayon etilgan. Bugungi kunda elektr energiyasiga bo‘lgan talabning ortib borishi va narxining oshishi melioratsiya hamda sug‘orishda ishlatilayotgan nasoslarning energiya sarfini kamaytirish uchun energiya tejamkor mexanizmlardan foydalanish zaruratini taqozo etmoqda. Oqimchali nasosni amaliyotda qo‘llash ishlari Sirdaryo viloyati Guliston shahar hududidagi vertikal drenajda amalga oshirilib, tabiiy dala sharoitida gidravlik parametrlar suv sarfining 0,8–1,6 l/s gacha va quvurdagi bosimi 0,5–1,0 atm gacha oralig‘ida sinov ishlari olib borildi. Dala va laboratoriya tadqiqot natijalari o‘zaro qiyosiy baholanib, nisbiy sarf va nisbiy napor orasidagi bog‘lanishlar olingan. Ularning aniqlilik darajasi koreliatsiya koeffitsiyenti (R2 = 0,91) orqali asoslangan. Oqimchali nasoslarni vertikal drenajlarda qo‘llash bo‘yicha shartlar va tavsiyalar qayd etilgan.

В статье изложены результаты исследований по пра ктическому применению струйного насоса, использующего энергию потока, в целях повышения энергоэффективности вертикальных водостоков в ирригационно-мелиоративных системах. Сегодня растущий спрос на электроэнергию и рост её стоимости диктуют необходимость использования энергоэффективных механизмов для снижения энергопотребления насосов, используемых для мелиорации земель и орошения. Работы по практическому применению струйного насоса проводились на вертикальном дренаже в районе города Гулистана Сырдарьинской области, испытательные работы проводились в естественных полевых условиях в диапазоне гидравлических параметров расхода воды 0,8–1,6 л/с и давления в трубопроводе 0,5–1,0 атм. Результаты полевых и лабораторных исследований были сравнительно оценены, и были получены связи между относительным расходом и относительным напором. Уровень их точности основан на коэффициенте корреляции (R2 = 0,91). Отмечены условия и рекомендации по применению струйных насосов в вертикальных водостоках.

The article presents findings from research into practical application of a jet pump utilizing flow energy in view to improve energy efficiency of vertical drains in irrigation and reclamation systems. Increasing demand for electricity and its rising cost nowadays dictate the need for energy efficient mechanisms to reduce the energy consumption of pumps used for land reclamation and irrigation. Works on practical application of the jet pump were carried out on vertical drainage in the area of Gulistan city of Syrdarya province, test works were implemented in field conditions in the range of hydraulic parameters of water flow rate 0,8-1,6 l/s and the pipeline pressure of 0,5-1,0 atm. Comparative evaluation of results from the field and laboratory tests retrieved relationships between relative flow rate and relative head. Their level of accuracy is based on the correlation coefficient (R2 = 0.91). The paper provides conditions and recommendations for the use of jet pumps in vertical drains.
