ZGKQ50-W型抗旱灌溉机与微喷带组合应用性能参数试验

为解决现有机组设备沉重、运行成本不清以及与微喷带组合方式不明确的问题,设计研发了ZGKQ50-W型抗旱灌溉机组,机组选择汽油泵作为动力设备。试验测试了机组首部耗油量及配备4种常用型号微喷带的喷洒均匀系数,计算并验证了与不同微喷带组合后的最大灌溉面积以及灌溉667 m~2土地所需的运行成本。结果表明,机组首部与微喷带组合后的最大运行流量为20 m~3/h,与Ⅰ号微喷带组合后喷洒均匀系数低于70%,与Ⅱ号微喷带的组合方式为2条33 m以2 m的间距并列铺设,组合后的喷洒均匀系数为73.30%,灌溉667 m~2土地运行成本为470.9元;与Ⅲ号微喷带的组合方式为3条83.3 m以3.5 m的间距并列铺设,组合后的喷洒均匀系数为77.06%,灌溉667 m~2土地运行成本为175.2元;与Ⅳ号微喷带的组合方式为3条99.3 m以2 m的间距并列铺设,组合后的喷洒均匀系数为77.40%,灌溉667 m~2土地运行成本为320.0元。综合考虑喷洒均匀系数及运行成本,Ⅲ号微喷带省工省时,适合进行大面积灌溉;Ⅱ号微喷带灌溉区域灵活性强,适合在小型零散地块使用。

Testing the Performance of ZGKQ50-W Machine Equipped with Micro-sprinkling Hoses Used for Irrigation in Drought

We designed the ZGKQ50-W machine equipped with deiseal pump to resolve some problems such as heavy weight, untidy operation and uncertain costs, facing irrigation equipments currently used for irrigation in drought. In this paper, we tested its performance in fuel consumption, irrigation uniformity, maximum control ar-ea, and cost for irrigating a 667 m2 of land.The results showed that the maximum flow rate of the new equipment was 20 m3/h after combining with micro-sprinkler hose.Its irrigation uniformity, when connected to Type Ⅰ hose, was less than 70%. When connected to two 30 m long Type Ⅱ hoses separated by 2 m, the irrigation uniformity was 73.30%, costing 470.9 Yuan to irrigate the 667 m2 of land. Equipping with two 83.3 m long Type Ⅲ hoses separated by 3.5 m gave an irrigation uniformity of 77.06%and running cost of 175.2 Yuan. We also tested the performance of the system when connected to two 99.3 long Type Ⅳ hoses separated by 2 m, and the irrigation uniformity and running cost were 77.40%and 320.0 Yuan respectively. In summary, combining the new system with Type Ⅲ hose was suitable for irrigating large area due to the saving in time and labor, while equipping with Type Ⅱ hose was more suitable for irrigating small scattered plots.
