電子無負壓供水系統裝置工作原理

電子器件無真空供電試驗裝置直接性串接在日常自來水供電管上，在自吸水泵水進端和滿水后端對應重新安裝學習壓力值差傳還是器，終端采集隨時學習壓力值差發展數字信號并進入基地掌控機組。其一個浮堰機組、很糊掌控機組、手動隨著機組、學習壓力值差PID把握單元測試，經把握基地協調性運算把握抽水泵組一鍵進行。

智能智能虛假主機浮堰可在浸供水管公司管道中成型一層虛假主機浮堰，其效用與真實可靠浮堰類似，其浮堰層面可憑借操控蓋板靈活機動因素，預期程序開機運行時操控前面浸水關鍵阻力要自始至終不低過智能智能浮堰因素值，這就加強組織領導了前面自來供水管公司官網中工程相關普通用戶免受差壓影響到，供水管公司安裝只對超過智能智能浮堰的蓄需儲供的水量完成在線免費疊壓，充沛合理利用了自來供水管公司官網中工程已有阻力，較大 幅度過的節電了電，當自來供水管公司官網中工程因內部故障造成來水阻力及來蓄需儲供的水量欠缺時，超過智能智能浮堰的蓄需儲供的水量不斷被體統負壓輸出，以可以保障供水管公司的間斷性性。當超過浮堰的蓄需儲供的水量為零時，生產環保設備自己為止開機運行。當自來供水管公司官網中工程回到正常情況只有超過浮堰的蓄需儲供的水量現身，生產環保設備會自己程序開機運行負壓。

隨著電子器材無壓力差供電系統傳動裝置隨時串接在污水供電系統管上，減少了傳統的的水箱的，從本質上上防止出現了水與層結沾染而產生的首次弄臟。

電子無負壓產品優點

1、 征地賠償體積小。

2、 外出結構件少、范圍小，電子器件感測器結構件不被水堿沉渣影晌。

3、 防正壓階段可選擇來蓄水量同樣增壓，來數量加數量，必須的流量為零時才停止。

4、 合理有效愛護自來水管FDA監督管理局阻力不會受到氣體壓力應響，且快速設置改變輕松更方便。

5、 液壓管路串并聯，充足進行了純凈水取水水壓，專用設備運動生產率高。

6、 環保設備全封閉空間與包氣隔離，保障水質標準沒有破壞。

Working principle of electrical water supplying system device without negative pressure

 The device is directly connected to the tap water supplying pipes with a concatenation, and pressure sensors will be mounted respectively at the water in-let and out-let ends to collect real time pressure alterative signal and send to the central control unit. Its Virtual floating weir unit, fuzzy control unit, automatic follower unit, pressure PID control unit, through the central coordinative calculation, will control the water pump group to automatically work.

Electrical virtual floating weir can generate a virtual floating weir in water in-letting pipes, its function is equal to real floating weir, whose height can be adjusted smartly through the control panel, its actual motion can sustain the front end water in-letting pressure to be always higher than the value fixed by the electrical floating weir, and thus to ensure that the users surrounding the front end water pipe net won’t be affected by the negative pressure. The water supplying devices only make online overlying of the water quantity that has crossed the floating weir, which has sufficiently taken usage of the original pressure of the water pipe net, thus to save the power as much as possible. When the water pipe net can’t supply enough water or water pressure because of any error, the water crossing the floating weir will be continuously output with additional pressure from the system, thus to sustain continuous water supply. When there is no water crossing the floating weir, the device will stop automatically to accumulate pressure, when the water supply pipe net is recovered, only there is water crossing the floating weir, the device will automatically operate and accumulate pressure.

Because the electrical water supplying devices without negative pressure is connected directly to the water supplying pipe, the traditional water tank is saved, thus to avoid the secondary pollution from the contact between water and atmosphere.

Advantage of electrical products without negative pressure:

     1、Small area taken.

      2、Less parts and areas interfered by water, electrical sensing parts won’t be affected by incrustation.       3、The negative pressure protective process can accumulate pressure symmetrically as per the incoming water quantity, which only stops when the water flow is zero.       4、Effectively protect the water supply pipe net from being affected by the negative pressure, with smart setting and debugging modes.       5、Pipe line is connected with concatenates, which sufficiently takes advantage of the pressure from incoming water, more efficiency.       6、Device is totally sealed and isolated from atmosphere, thus to avoid pollution.
