自压滴灌无用电过滤装置与系统流量平衡关系

The Pressure Drip Irrigation Engineering Without Electricity Filter Unit and System Flow Balance

新疆牧业灌区由于无电供应,目前采用地面灌溉。地面灌溉灌水量多、地形坡度大等原因引起大量水土流失。灌区下游排水不畅洼地沼泽化面积剧增,地下水位上升导致土壤盐碱化,弃田面积逐渐扩大、种植面积萎缩,实现节水灌溉工程的难度大。为解决上述问题,研制了滴水调节器和自压滴灌工程无用电过滤装置。充分利用自然地形落差,解决了自压滴灌工程水源的过滤、排沙、冲沙及自行冲洗等问题。同时渠道进水流量、调水池的调节流量、集水桶流量及系统流量之间建立了平衡关系,介绍了系统流量的计算方法,为无电牧业灌区实现节水灌溉技术提供理论依据。

The animal husbandry in Xinjiang Irrigation Area has no electricity supply, so it uses the surface irrigation. Surface irriga- tion consumes more water, such as large terrain slope causes a large amount of water loss and soil erosion. Irrigation district of the downstream drainage not free lowland swamp area is on the rise, so is the ground water level in soil salinity, the abandoned field area expands gradually, the planting area is shrinking. It is difficult to realize water-saving irrigation projects. To solve the above prob- lem, this paper makes full use of natural terrain, and solves the pressure drip irrigation engineering water filtration, and sand, flush- ing, washing and so on. a balanced relationship is established between flow and system flow, this paper introduces the system flow calculation method, and for animal husbandry irrigation areas without electricity can provide a theoretical basis for water-saving irri- gation technology.
