電子無(wú)負(fù)壓供水系統(tǒng)裝置工作原理

電子無(wú)負(fù)壓供水裝置直接串接在自來(lái)水供水管上，在水泵進(jìn)水端和出水端分別安裝壓力傳感器，采集實(shí)時(shí)壓力變化信號(hào)并送入中心控制單元。其虛擬浮堰單元、模糊控制單元、自動(dòng)跟隨單元、壓力PID控制單元，經(jīng)控制中心協(xié)調(diào)運(yùn)算控制水泵組自動(dòng)運(yùn)行。

電子虛擬浮堰可在進(jìn)水管道中形成一道虛擬浮堰，其作用與真實(shí)浮堰相同，其浮堰高度可通過控制面板靈活設(shè)定，實(shí)際運(yùn)行時(shí)控制前端進(jìn)水目標(biāo)壓力始終不低于電子浮堰設(shè)定值，這就確保了前端自來(lái)水管網(wǎng)周邊用戶不受負(fù)壓影響，供水裝置只對(duì)越過電子浮堰的水量進(jìn)行在線疊壓，充分利用了自來(lái)水管網(wǎng)原有壓力，最大幅度的節(jié)約了電能，當(dāng)自來(lái)水管網(wǎng)因故障產(chǎn)生來(lái)水壓力及來(lái)水量不足時(shí)，越過電子浮堰的水量繼續(xù)被系統(tǒng)加壓輸出，以保證供水的連續(xù)性。當(dāng)越過浮堰的水量為零時(shí)，設(shè)備自動(dòng)停止運(yùn)轉(zhuǎn)。當(dāng)自來(lái)水管網(wǎng)恢復(fù)正常只要有越過浮堰的水量出現(xiàn)，設(shè)備會(huì)自動(dòng)運(yùn)行加壓。

由于電子無(wú)負(fù)壓供水裝置直接串接在自來(lái)水供水管上，省去了傳統(tǒng)的水箱，從根本上避免了水與大氣接觸而形成的二次污染。

電子無(wú)負(fù)壓產(chǎn)品優(yōu)點(diǎn)

1、 占地面積小。

2、 涉水部件少、面積小，電子傳感部件不受水垢雜質(zhì)影響。

3、 防負(fù)壓過程可根據(jù)來(lái)水量同步加壓，來(lái)多少加多少，只有流量為零時(shí)才停機(jī)。

4、 有效保護(hù)自來(lái)水管網(wǎng)壓力不受負(fù)壓影響，且設(shè)定調(diào)整靈活方便。

5、 管路串聯(lián)，充分利用了自來(lái)水進(jìn)水壓力，設(shè)備運(yùn)行效率高。

6、 設(shè)備完全密閉與大氣隔絕，確保水質(zhì)不受污染。

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.
