The motor and pump of vertical motor are vertical arranged on the ground , it ' s smaller footprints and suitable for high - rise buildings water supply , not recommended to the court 长轴泵的电机在地面而泵体在水下,优缺点综合了潜水泵和卧式泵，使用寿命长，所以在通常的球场喷灌系统中为最佳选择，在球场喷灌泵站占90以上。
Based on the analyses of the investment of nozzle tube net and relationship between the annual operation cost and tube diameter function of a fixed spray irrigation system , a mathematic model to calculate the economical tube diameter of a spray irrigation system is developed by using the minimum expense norm and nonlinear planning theory in engineering economic analysis , and a direct calculation formula for the economical tube diameter in unrestrained conditions is presented 摘要在分析了固定式喷灌系统的管网投资、年运行费用与管径函数关系的基础上，利用工程经济分析中费用最小化准则和非线性规划理论，建立了求解喷灌系统管网经济管径的数学模型，并给出了无约束条件直接求解经济管径的计算式。
Taking the square wetted areas as an example , if we put this kind of sprinkler into practice , we not only can g et higher quality of amusement but also simplify the arrangement of the sprinklers . the total amount of the sprinklers and pipe networks can be decreased remarkably . then the engineering investment can be reduced a lot , all this can boost the development of water irrigation industry 如果在实际喷灌中采用这种喷头来控制方形喷洒域，那么其不仅有很高的观赏性且喷头的组合形式将更为简单，喷灌系统的喷头总数及管网设置可大大的减少，节省工程投资，促进节水灌溉事业发展。
