自动消防水炮由于受管网压力、安装高度、空气阻力等因素影响,会造成射流轨迹发生变化,而不能准确射向火源。本文提出了一种实用的补偿修正方案,即在固定的安装环境下对其俯仰角进行修正,使落水点准确射中火源。在不同距离上重复上述射水过程,形成射流参数射表,由不同安装环境下的多个射流参数表组成射流参数数据库。并通过软件模拟仿真补充完善该数据库供工程中调用,从而提高射水精度和灭火效率。
Automatic fire water cannons due to pipe network pressure, installation height, air resistance and other factors, will result in changes in jet trajectory, and can not be accurately fired fire. This paper presents a practical compensation correction program, that is, in a fixed installation environment to correct its pitch angle, so that the exact landing fire point fire source. At different distances, the above water jetting process is repeated to form a jet parameter jet meter, which is composed of a plurality of jet parameter meters under different installation environments. And complemented by software simulation to complement the database for engineering calls, thereby improving water accuracy and fire fighting efficiency.
