恒壓供水系統

Issuing time:2018-11-16 09:36
供水系統是國民生產生活中不可缺少的重要一環。傳統供水方式占地面積大,水質易污染,基建投資多,而最主要的缺點是水壓不能保持恒定,導致部分設備不能正常工作。變頻調速技術是一種新型成熟的交流電機無極調速技術,它以其獨特優良的控制性能被廣泛應用于速度控制領域,特別是供水行業中。由于安全生產和供水質量的特殊需要,對恒壓供水壓力有著嚴格的要求,因而變頻調速技術得到了更加深入的應用。
將管網的實際壓力經反饋后與給定壓力進行比較,當管網壓力不足時,變頻器增大輸出頻率,水泵轉速加快,供水量增加,迫使管網壓力上升。反之水泵轉速減慢,供水量減小,管網壓力下降,保持恒壓供水。
