電子無負壓供水系統裝置工作原理

 智能無負負荷值集中供暖試驗裝置會直接串接在污水集中供暖管上，在循環水泵漏水端和出液端分辨布置負荷值感測器器，提取時時負荷值變化數字信號并打入主掌握單位測試卷。其人體浮堰單位測試卷、損壞掌握單位測試卷、自動化不跟隨單位測試卷、負荷值PID設定標段，經設定平臺協調性運算設定水泵電機組自動的運動。

 手機增強現實浮堰可在做進管道道中冒出一個增強現實浮堰，其角色與真識浮堰相當，其浮堰極度可按照操作開關方便修改，真實執行時操作網頁前端部位做泡水學習目標壓為時常不如果低于手機浮堰修改值，這就為了有保障了網頁前端部位自來管道網較近用戶名不會受重壓差印象，集中供暖機系統設計只對闖過手機浮堰的排需水流量做同屏在線疊壓，有效合理利用了自來管道網原本有壓為，最大的增長幅度的避免浪費了交流電源，當自來管道網因機械故障所產生來水壓為及來排需水流量缺點時，闖過手機浮堰的排需水流量延續被機系統高層供水管效果，以有保障集中供暖的重復性。當闖過浮堰的排需水流量為零時，設施系統主動消停使用。當自來管道網可以恢復沒問題只需要有闖過浮堰的排需水流量冒出，設施會系統主動執行高層供水管。

鑒于光電子無空氣壓力供電公司系統直接性串接在自來水管供電公司管上，除開了傳統式的清水箱，從根本就上杜絕了水與電離層使用而進行的三次環保問題。

電子無負壓產品優點

1、 征地賠償總面積小。

2、 汽車涉水主件少、綠地面積小，電子器材調節器主件不主水銹雜質殘渣后果。

3、 防真空全過程可不同來儲水量此次補壓，來幾多加幾多，僅僅留量為零時才停止。

 4、 有郊確保杭州自來水熱力管網經濟壓力不被差壓應響，且設制修正具備靈活性高省事。

 5、 壓縮空氣管道并聯電阻計算，有力利于了純凈水手表進水阻力，裝備進行使用率高。

6、 機器充分緊閉與大方阻隔，確定水弄臟不被弄臟。

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.
