Öntözötelepek hidraulikai szimulációja 259 расчетными и опытными кривыми, а также на сдвиг кривых в результате засорения труб и утечки из них в период эксплуатации. Поэтому очевидно, что для точной симуляции необходимы опытные графические характеристики. Испытание подземных трубопроводов проводилось с помощью вычислительных машин. Исходя из результатов исследований, данная работа дает рекомендации по планомерной и экономичной эксплуатации и техническому усовершенствованию орошаемого участка. * * * Hydraulic simulation of irrigation sections by S. NAGY In order to gain added operation experience, investigations have been performed at the irrigation section Kungyalu-I, situated at a distance of 50 km from Szolnok town. The most important task consisted of determining the performance curves of the pumps and the irrigation equipment (sprinklers of the Volshanka type and manually relocated laterals). For computer simulation the Q — H curves have been determined for 20 laterals analytically, for five laterals by field measurements as well (Figs. 2 — 4). The figures reveal clearly the differences between the curves calculated and measured actually, further the shift in the curves of laterals clogged during operaiion and of those which developed leaks. Evidently, for exact simulation the actual performance curves are needed. The buried pipe network has been analysed by means of a computer. Suggestions are eventually submitted for the rational and economical operation, as well as for the technical development of the sprinkler irrigation section.
