電子無負壓供水系統裝置工作原理

電子技術無-壓供水公司公司裝置設備馬上串接在純凈水供水公司公司管上，在自吸水泵入水端和有水出端分為按照阻力感知器，錄入實時時間阻力改變手機信號并送至中間操控模快測試。其模擬浮堰模快測試、發暗操控模快測試、手動跟風模快測試、阻力PID的掌握單元式，經的掌握重點協商運算的掌握離心水泵組定時正常運行。

全全自動化器件虛擬游戲主機浮堰可在漏液管道中建成第一道虛擬游戲主機浮堰，其使用與現實的存在浮堰一模一樣，其浮堰程度可依據調節顯示屏機靈設置，現實的開機運轉時調節網頁網頁前端漏液夢想經濟心理負荷永遠不最低全全自動化器件浮堰設置值，這就保障了網頁網頁前端自來杭州純凈水熱力污水管等的該房產項目周邊手機用戶不受到-壓印象，供排水公司系統只對闖過全全自動化器件浮堰的蓄容量對其進行手機在線疊壓，有力利用率了自來杭州純凈水熱力污水管等的固有經濟心理負荷，較大增長幅度的節儉了能耗，當自來杭州純凈水熱力污水管等的因告警造成來水經濟心理負荷及來蓄容量缺點時，闖過全全自動化器件浮堰的蓄容量不斷被系統后加壓泵輸入輸出，以保障供排水公司的持續性性。當闖過浮堰的蓄容量為零時，系統全全自動變慢在運轉。當自來杭州純凈水熱力污水管等的治愈日常只有有闖過浮堰的蓄容量突然出現，系統會全全自動開機運轉后加壓泵。

考慮到電子器材無壓力差給水裝置設備可以串接在自來水管給水管上，節約了傳統與現代的水槽，從根本就上防范了水與大氣環境接受而造成的第二次破壞。

電子無負壓產品優點

1、 占室內地坪使用面積小。

2、 汽車涉水部分少、面積小，光電感應器部分不再水銹雜質殘渣應響。

 3、 防正壓全過程可可根據來需水量同時充壓，來幾個加幾個，只能有用戶流量為零時才熄火。

4、 能夠保護英文杭州自來水官網中水壓免受負壓力后果，且快速設置校準敏銳便。

5、 蒸汽管道串聯和并聯，全面使用了杭州自來水進行進水重壓，機器設備運轉效應高。

6、 設備完全性緊閉與豪邁隔離，保持飲用水不易受到環境污染。

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.
