Methodology for assessing the efficiency of water jet pumps in auxiliary systems of irrigation pumping stations

The reliability and efficiency of irrigation pumping stations operation primarily depends on the well-coordinated all systems. Drainage system should ensure that building territory station are not flooded by drainage (filtration) water. At many (especially those with long pressure lines), water jet pumps installed as for out experience operating such plants has revealed their undeniable advantages in comparison conventional vane centrifugal (type K D) – sufficient due to simplicity design, absence rubbing parts installation, possibility contaminated liquids use power supply. But this, extremely low-efficiency. To justify pumps, a methodology is needed would allow comprehensive consideration main factors affect reliability, ease energy system. On example “Kiziltepa-2”, these were identified was calculated. Various applications considered, evaluated.
