在试验室内,对研制的微压灌水器进行了水力性能试验。试验结果表明:在微压(2~5 m)工作时,新型微压滴灌灌水器在自由出流状态下的出流规律符合设计要求;在工作压力范围内,微压灌水器的流量稳定,变化小;新型微压滴灌灌水器在连续工作1周后流量略有变化,出流更加均匀;微压滴灌灌水器抗堵塞能力强,性能可靠。
In the laboratory, the developed micro-pressure emitter for hydraulic performance test. The test results show that the outflow regularity of the new micro-drip irrigation emitter meets the design requirements under the conditions of micro-pressure (2 ~ 5 m), and the flow of the micro-pressure emitter is stable under the working pressure range. Little change; the new micro-pressure drip irrigation water flow in a week after a slight change in flow, more uniform flow; micro-pressure drop irrigation emitter anti-clogging ability, reliable performance.
