(1) 變頻供水(shui)設備(bei)
根據壓(ya)力(li)變送器送來的(de)信號,控制電(dian)機泵(beng)組的(de)速(su)度及運行臺數調節流(liu)量(liang)達到恒壓(ya)或變壓(ya)供(gong)水，當夜間小流(liu)量(liang)時，可切(qie)換(huan)到附(fu)屬小泵(beng)或小型氣壓(ya)罐來維持供(gong)水壓(ya)力(li)。
(2) 生活、消防共用供(gong)水(shui)設備(bei)
生活供水(shui)時(shi)(shi)，設(she)備運行在低(di)壓(ya)(ya)變頻狀態；當發(fa)生火(huo)災時(shi)(shi)打開消(xiao)防栓，管(guan)路中的(de)流量開關發(fa)出信號（亦(yi)可(ke)由消(xiao)防栓中的(de)消(xiao)防按紐(niu)或電控柜(ju)上的(de)按紐(niu)啟動），微機立即控制泵組使壓(ya)(ya)力上升至消(xiao)防壓(ya)(ya)力，并自動切(qie)斷(duan)生活供水(shui)。此(ci)方(fang)式可(ke)滿足消(xiao)防對系(xi)統壓(ya)(ya)力的(de)要求(qiu)。
(3) 專用消防(fang)設備
2個穩定(ding)泵，2個為消防泵，平時(shi)穩定(ding)泵工作。水在管路(lu)中形成一個小循環，維持(chi)一定(ding)系統壓力，當出(chu)現火警(jing)打開(kai)消防栓時(shi)，流量開(kai)關發出(chu)信號，通(tong)過(guo)電控柜帶動消防泵，滿足消防用水要(yao)求。
