近几年来,随着喷灌技术的迅速发展,在群众性的科学实验活动中一批性能较好的喷灌机具相继产生,喷灌面积不断扩大。但是,喷灌机具仍然存在型号杂、品种多、性能不全,成本高、“三化”程度低等问题。因此,喷灌机具的“三化”工作必须抓紧抓好。水电部、一机部于1977年4月共同组织了摇臂式喷头系列和喷灌泵系列两个联合设计组,用了不到一年的时间,分别完成了 PY(?)系列喷头和喷灌泵系列的设计、试制和试验工作,并均已通过部级鉴定。同时,设计组还协助喷灌机具标准起草小组,进
In recent years, with the rapid development of sprinkler irrigation technology, a batch of sprinkling irrigation equipment with good performance has been produced in mass scientific experiment activities, and sprinkler irrigation area has been expanding. However, there are still sprinkler type miscellaneous models, varieties, performance is incomplete, high cost, “three ” low degree of the problem. Therefore, irrigation equipment “three of ” work must pay close attention to. In April 1977, the Ministry of Water Resources and Electric Power jointly organized two joint design teams of the rocker arm type sprinkler pump series and the sprinkler irrigation pump series. In less than a year, they completed the PY (?) Series of sprinklers and sprinkler pumps Series of design, trial production and test work, and have passed ministerial appraisal. At the same time, the design team also assisted the standard drafting team of irrigation equipment into
