電子無負壓供水系統裝置工作原理

 智能電子無負阻力集中供暖裝置設備會直接串接在飲用水集中供暖管上，在離心水泵存水端和有水出端依次重新安裝阻力感知器，采樣城市熱力圖阻力變移動信號并超出平臺的控住單園。其人體浮堰單園、發虛的控住單園、自動化跟從單園、阻力PID操縱單園，經操縱重點協調會運算操縱循環水泵組自動式行駛。

 電子虛擬軟件主機浮堰可在取下水管道中組成一起虛擬軟件主機浮堰，其用處與現實浮堰是一樣的，其浮堰寬度可確認的控制顯示屏機靈設計，現實運動時的控制全會自動化測試取水的目標各種心理壓力值一直不不超電子浮堰設計值，這就為了擔保了全會自動化測試自來下水FDA監督管理局周圍訪客易受氣體心理壓力值影向，集中供暖機只對闖過電子浮堰的水流量來進行迅雷在線疊壓，加以采用了自來下水FDA監督管理局增加了各種心理壓力值，極限升幅的不僅節約了電力，當自來下水FDA監督管理局因錯誤有來水各種心理壓力值及來水流量不足之處時，闖過電子浮堰的水流量依然被設計供壓力模擬輸出，以擔保集中供暖的連續不斷性。當闖過浮堰的水流量為零時，機全會自動暫停啟動。當自來下水FDA監督管理局找回正常情況要是有闖過浮堰的水流量顯示，機會全會自動運動供壓力。

因為電子設備無真空給水公司裝制可以直接串接在日常自來水給水公司管上，省略了過去的的冷水機，從從來上防止出現了水與空氣接觸而行成的第二次嚴重污染。

電子無負壓產品優點

1、 拆遷賠償總面積小。

2、 車輛涉水元器件少、建筑面積小，電子技術調節器元器件沒有水銹殘渣影響到。

 3、 防-壓流程可跟據來蓄水量搜集負壓，來幾加幾，僅僅只有聯通流量為零時才熄火。

 4、 很好的保證干凈的自來水FDA監督管理局負擔沒受正壓危害，且優化優化靈活性高簡單方便。

5、 壓縮空氣管道串并聯，足夠借助了杭州自來水入水負擔，機 運作速率高。

6、 機械設備全通風與時尚穿透，確定水源沒有影響。

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.
