摘 要：
The determination of the relationship between the Size of pressure regulator and the expenditure of energy in it is the basis of reasonably designing constant pressure sprinkler irrigation systems. This paper affirms through experiment that the expenditure of energy for initiating pump unit can be neglected, compared with that for running it, which provides a basis for building a model of energy expenditure in constant pressure sprinkler irrigation systems. By means of the model the relationship is analyzed between the size of pressure regulator and the expenditure of energy of the system.
