时针式喷灌机选用高、中压摇臂式喷头,电耗大,且在寒冷的气候条件下,无法进行喷灌作业。北方地区冬春喷灌按种水、早期喷灌苗水,气温均在摄氏零度以下,因而影响喷灌的正常进行。我国目前定型生产的Py_1系列摇臂式喷头,因档次稀,流量,压力差距大,不能适应时针式喷灌机的需要,我们应生产之急需,仿美林赛制造公司生产的《齐马提克》平移式喷灌机所采用《雨鸟》折射式喷头,设计了一套喷头,喷孔直径由2.5—8.1毫米,工作压力1.6—2.8公斤/厘米~2,流量为0.27—3.28米~3/时,档次35种,
Hour needle irrigation machine selection of high and medium pressure rocker nozzle, power consumption, and in cold climates, can not be sprinkler irrigation operations. Spring and winter sprinkler irrigation in northern China according to water, early sprinkler water, the temperature is below zero degrees Celsius, thus affecting the normal sprinkler. China’s current stereotypes production Py_1 series rocker nozzle, due to the grade dilute, flow, pressure gap, can not meet the needs of the hourglass irrigation machine, we should produce the urgent need, imitation Merlin 赛 manufacturing company’s “Zimatiac ”Pan-type irrigation machine used“ Rain Bird ”refraction nozzle, designed a nozzle, nozzle diameter from 2.5-8.1 mm, the working pressure of 1.6-2.8 kg / cm ~ 2, the flow rate of 0.27-3.28 m ~ 3 / When the grade of 35 species,
