3 performance rating evaluation index

This standard through the assessment of pipe irrigation pump the provisions of the flow, the provisions of the head and pipe irrigation fuel consumption rate or tube irrigation efficiency to determine the pipe

Performance level. The performance grade of the pipe filling machine is divided into three grades. 1, 2, 3, and the performance is the highest. The evaluation of each grade of performance means

The values shall be in accordance with Table 1.
