黑龙江省依安县多年来打了一大批电井,在农业抗旱灌溉中起了重要作用。但由于许多电井配套不合理,效率低而能耗高,既加重了农民负担,又影响了溉灌积极性。为了消除这些弊端,去年这个县水利科技人员对依安镇33眼电井进行了有成效地技术改造。其方法是: 一、测试工作电井测试是在不改变原工作状态下于现场进行的,从而取得了机泵正常工作参数。 1、静水位、动水位和扬程的测量。选用音响回测量法进行。开机前先测量静水位,机泵正常运转30—60分钟后,再测动水位,同时测水泵总扬程,反复测2—3遍, Yi’an County, Heilongjiang Province, hit a large number of wells over the years and played an important role in agricultural drought-resistant irrigation. However, because many well supports are unreasonable, inefficient and energy-intensive, they not only increase the peasant burden but also affect the enthusiasm of irrigation. In order to eliminate these drawbacks, last year, the county’s water conservancy scientific and technical personnel conducted an effective technological transformation of the 33 wells in Yi’an. The method is: First, the test work Well test is carried out in the field without changing the original working conditions, so as to obtain the normal operating parameters of the pump. 1, static water level, water level and lift measurements. Use audio back to measurement method. Before the start of the measurement of static water level, the normal operation of the pump after 30-60 minutes, and then measure the water level, while measuring the total pump head, repeatedly measured 2-3 times,
