武汉市水利科学研究所、武汉水利电力学院、武汉市谌家矶公社等三个单位根据水利部下达的喷灌系统自动化的科研课题,在省市有关单位的大力协作下于去年十二月在谌家矶初步建成了一个灌溉面积为133亩的自动控制固定式喷灌系统。经初步检验证明,该系统结构较为简单,运行可靠,自动化程度较高。为了便于维修、运行可靠和经济合理该系统采用了继电器控制的线路,根据
Wuhan Institute of Water Conservancy, Wuhan Institute of Water Conservancy and Electric Power, Wuhan Chenjiaji commune and other three units under the Ministry of Water Resources issued sprinkler irrigation system automation research projects in the provinces and cities under the concerted efforts of relevant units in December last year in Chen Jiaji initially built an irrigation area of 133 acres of automatic control of fixed sprinkler irrigation system. After preliminary examination proved that the system structure is relatively simple, reliable operation, high degree of automation. In order to facilitate maintenance, reliable and economical operation of the system uses the relay control circuit, according to
