恒压供水系统

Issuing time:2018-11-16 09:36
供水系统是国民生产生活中不可缺少的重要一环。传统供水方式占地面积大,水质易污染,基建投资多,而最主要的缺点是水压不能保持恒定,导致部分设备不能正常工作。变频调速技术是一种新型成熟的交流电机无极调速技术,它以其独特优良的控制性能被广泛应用于速度控制领域,特别是供水行业中。由于安全生产和供水质量的特殊需要,对恒压供水压力有着严格的要求,因而变频调速技术得到了更加深入的应用。
将管网的实际压力经反馈后与给定压力进行比较,当管网压力不足时,变频器增大输出频率,水泵转速加快,供水量增加,迫使管网压力上升。反之水泵转速减慢,供水量减小,管网压力下降,保持恒压供水。
