目前,小型机电灌站的管路直径,大部分是按水泵口径配套的,即3时泵配3时管,4时泵配4时管,……。按这种方式配套,在很多情况下要造成管路阻力大,烧油耗电多,浇地成本高的情况。因此,为小型机电灌站选配合适直径的管路,是小型机电灌站建设中需要很好解决的一个问题。我们知道:对于一定流量的水泵,如选配的管路直径小,投资 At present, most of the pipe diameters of mini mechanical and electrical filling stations are matched according to the diameter of the water pump, that is, 3 o’clock pump is equipped with 3 o’clock pipe and 4 o’clock pump is equipped with 4 o’clock pipe. In this way supporting, in many cases to cause a large pipeline resistance, oil burning more electricity, pouring land high cost situation. Therefore, it is an issue that needs to be well solved in the construction of small mechanical and electrical filling stations for matching the pipe with the proper diameter for the small electromechanical filling station. We know: For a certain flow pumps, such as the optional pipeline diameter, investment
