嘉兴县新丰公社为了节约农业排灌用电,近十年来,大力改建旧机埠,推广落井安装,根据实际扬程,调节转速,减少电耗。降低灌溉成本,取得显著成效。新丰公社地处水网圩区,地势低洼,常年实际扬程约为2.5米,而旧机埠(岸边卧式安装)的经济扬程(*)普遍超过实际扬程50～60％,同时增大吸程和管路摩阻(主要为底阀)。落井安装后,这些不利的工作状况,得到改善,从而达到节约用电的目的。根据我们对东胜
In order to save agricultural irrigation and drainage irrigation power, Xinfeng Commune in Jiaxing County has vigorously rebuilt the old port in the past 10 years to promote the installation of drop shafts and adjust the speed according to the actual lift to reduce power consumption. Reduce irrigation costs, achieved remarkable results. Xinfeng commune is located in the water network polders, low lying, perennial actual lift is about 2.5 meters, while the old port (shore horizontal installation) of the economic head (*) generally more than the actual lift 50 ~ 60%, while increasing Suction and pipeline friction (mainly the end of the valve). After falling into the well, these unfavorable working conditions have been improved, so as to achieve the purpose of saving electricity. According to us Dongsheng
