Experimental Study on Micro-Pressure Hydraulic Characteristics of Drip Irrigation Emitters with Multiple Types of Channels

Abstract:

Article Preview

Reducing emitters’ working hydraulic pressure appropriately can cut down construction cost and running cost of the whole drip irrigation system. Reduction of the emitters’ working hydraulic pressure, however, will directly affect emitters’ hydraulic characteristics and anti-clogging property. In this study, experimental research into the hydraulic characteristics of multiple types of emitters under micro-pressure and compared the hydraulic characteristics with the ones under normal hydraulic pressure has been done. The experimental results showed that compensating emitters had poor water discharge uniformity at critical startup hydraulic pressure while non-compensating emitters, dripping arrows and dripping tape had consistent water discharge uniformity under micro-pressure and under normal pressure.
