目前,各种型号的水泵已在全省各地广泛使用,但不少农户因选型、配套、安装不当,造成电力损耗过大,不能发挥水泵最高效益。如何节约电能,提高农用水泵的使用效率呢?笔者认为应从以下三个方面入手。 1、选型 农用水泵型号众多,选用时应当按照排灌实际需要的扬程和流量选择水泵。要求水泵的额定扬强等于泵站的地形扬程(即实际扬程)与损失扬程之和,但不少农 Currently, various types of pumps have been widely used throughout the province, but many farmers due to selection, ancillary and improper installation, resulting in excessive power loss, can not play the highest efficiency pumps. How to save energy, improve the efficiency of agricultural water pump it? I think the following three aspects should be started. 1, many types of agricultural pump selection, selection should be based on the actual needs of irrigation and drainage head and flow selection pump. Requires the rated capacity of the pump is equal to the pumping station topography lift (that is, the actual head) and the loss of the sum of head, but many farmers
