摘要：This paper presents two examples of exploitation of water energy that can be used in the irrigation field. First of these examples is the hydraulic transformer type A. Barglazan used for irrigation, pumped water is taken directly from the river’s well, using a hydraulic pump which simultaneously carried out a double transformation in this way: hydraulic energy into mechanic energy and mechanical energy into hydraulic energy. Technology preparation and devices design was done in record time, seeing that this constructive solution is more robust, reliable and with improved energy performance versus the laboratory prototype. The experimental research which was made at 1:1 scale proved their good function over time. Another example is the hydraulic hammer (hydraulic pump) that uses low-head energy to pump water, with a global efficiency of about 10 - 50%. Currently, the new situation of private ownership of land provides conditions for new pumping microstations to be made where irrigation is necessary and optimal hydraulic locations exist.is
