Today, after school, my friends asked me to have dinner with them, I felt so happy and went the restaurant with them. Then I found they wanted to eat buffet, I was so happy, because I always wanted to have buffet, I could eat a lot of food. As we paid the money more than we usually spent, so all of us wanted to eat as more as possible, even though we were full enough, we still tried to eat. I would go the wash room many times, so that I could continue to eat. I found eating the buffet should be a happy thing for me, but now it seemed to be a kind of torture, I always told myself to eat more than I could bear, my stomach hurt. The experience to eat buffet lets me realize that I should enjoy the food instead of eat more than I could bear.
如果有了以上9個方面的對比,就基本能辨別出無負壓的優(yōu)與劣了。
蚌埠箱式無負壓供水設(shè)備工作原理
設(shè)備投入使用,自來水管網(wǎng)的水進入供水罐,罐內(nèi)空氣從真空消除器排除,待水充滿后,真空消除器自動關(guān)閉。當自來水管網(wǎng)壓力能夠滿足用水要求時,系統(tǒng)由旁通止回閥向用水管網(wǎng)直接供水;當自來水管網(wǎng)壓力不能滿足用水需求時,系統(tǒng)壓力信號由遠傳壓力表反饋給變頻控制器,水泵運行,并根據(jù)用水量的大小自動調(diào)節(jié)轉(zhuǎn)速恒壓供水,若運轉(zhuǎn)水泵達到工頻轉(zhuǎn)速時,則啟動另一臺水泵變頻運轉(zhuǎn)。 水泵供水時,若自來水管網(wǎng)的水量大于水泵流量,蚌埠箱式無負壓供水設(shè)備系統(tǒng)保持正常供水;用水高峰時,若自來水管網(wǎng)的水量小于水泵流量時,供水罐內(nèi)的水作為補充水源仍能正常供水,此時,空氣由真空消除器進入供水罐,罐內(nèi)真空遭到破壞,設(shè)備確保了自來水管網(wǎng)不產(chǎn)生負壓,用水高峰過后,系統(tǒng)又恢復到正常供水狀態(tài)。當自來水管網(wǎng)停水,造成供水罐液位不斷下降,液位將信號反饋給變頻控制器,水泵自動停機,以保護水泵機組,供水罐可以儲存并釋放能量,避免了水泵頻繁啟動。
遠程控制系統(tǒng),蚌埠箱式無負壓供水設(shè)備可具備遠程監(jiān)控接口,利用GPRS/MODEM實現(xiàn)設(shè)備的有線或無線遠程控制,異地實時控制各泵工作狀態(tài)、實時壓力、變頻頻率等系統(tǒng)參數(shù),并對故障進行報警記憶處理。
多段壓力供水模式,設(shè)備可根據(jù)用戶用水特點設(shè)置多段供水方式,一般設(shè)置一天六時段不同壓力供水即可滿足用戶需要。時間設(shè)置可在人機界面上操作修改,操作簡單方便。設(shè)置好后由程序自動控制運行,根據(jù)預先設(shè)置好的時間自動更改出口壓力恒定值。該供水方式是在原有變頻恒壓基礎(chǔ)上進行的分時段供水,蚌埠箱式無負壓供水設(shè)備系統(tǒng)可在不同時間段內(nèi)設(shè)定不同的壓力值,在用水高峰期時,管網(wǎng)水頭損失較大,為保證zui不利點正常供水,出水口可設(shè)定較高壓力值;在一般用水量時,管網(wǎng)水頭損失相對減少,出水口設(shè)定壓力可適當降低;在小流量時,管網(wǎng)水頭損失較小,出水口壓力可以再適當降低;該供水方式可在原有變頻供水的基礎(chǔ)上進一步降低設(shè)備的后期運行費用。

Today, after school, my friends asked me to have dinner with them, I felt so happy and went the restaurant with them. Then I found they wanted to eat buffet, I was so happy, because I always wanted to have buffet, I could eat a lot of food. As we paid the money more than we usually spent, so all of us wanted to eat as more as possible, even though we were full enough, we still tried to eat.

是采用*的變頻調(diào)速器,具有系統(tǒng)壓力穩(wěn)定的功能。信號通過系統(tǒng)管道上的壓力傳感器,把信號P傳給微電腦控制器并與設(shè)定值P0進行比較,用比較結(jié)果P作為調(diào)節(jié)參量來改變變頻器輸出頻率f。因為水泵的轉(zhuǎn)速n及出口壓力P均與頻率f成正比。所以,當PP0時,頻率f下降,水泵轉(zhuǎn)速n變慢,P下降,這樣,就使系統(tǒng)壓力P始終逼近設(shè)定壓力P0。當系統(tǒng)水受熱膨脹后,導致壓力高于所設(shè)定的上限報警壓力值時,系統(tǒng)壓力控制器自動打開泄壓閥泄水降壓,當壓力恢復到正常值時,泄壓閥自動關(guān)閉,停止泄水降壓。

3、用途廣泛、適用性強
CDL4-12系列可作生活供水用,也可作消防供水用。可配置任意型號的水泵,當設(shè)備用于消防時,宜配備消防水泵;
4、功能全、智能化程度高
CDL4-12系列蚌埠箱式無負壓供水設(shè)備采用了*的變頻控制技術(shù)。具有軟啟動,有過載、短路、過壓、欠壓、缺相、過熱和失速保護等功能在異常,情況下能進行信號報警、自檢、故障判斷等,還可根據(jù)用水量的高低自動調(diào)節(jié)供水流量;
5、產(chǎn)品*、質(zhì)量可靠
CDL4-12系列使用的配件。經(jīng)過了諸多生產(chǎn)廠家的篩選,具有可靠的質(zhì)量保證,產(chǎn)品中的關(guān)鍵零部件,如:電機、水泵軸承、變頻器、斷路器、接觸器、繼電器等還采用了、國內(nèi)產(chǎn)品;
6、個性化設(shè)計、獨樹一幟
CDL4-12系列可根據(jù)自來水管網(wǎng)壓力穩(wěn)定情況,配置小型氣壓罐,避免水泵頻繁啟動,以延長設(shè)備使用壽命,其蓄能、穩(wěn)壓性能更加顯著。
蚌埠箱式無負壓供水設(shè)備用水原理
用水高峰時,若水泵流量大于自來水給水管網(wǎng)的流量,v穩(wěn)流調(diào)節(jié)罐內(nèi)的水作為補充水源仍能保持一定時段的正常供水,此時空氣經(jīng)真空消除器進入罐內(nèi),破壞了罐內(nèi)的真空形成,確保自來水給水管網(wǎng)不產(chǎn)生負壓;用水高峰過后,系統(tǒng)又恢復正常供水狀態(tài);
當自來水管網(wǎng)停水時,蚌埠箱式無負壓供水設(shè)備穩(wěn)流調(diào)節(jié)罐內(nèi)的水位不斷下降,液位探測器信號反饋給變頻控制器,水泵自動停機,以保護水泵機組;
夜間小流量用水且自來水給水管網(wǎng)壓力不能滿足要求時, 蓄能罐可以釋放其貯存能量,避免了水泵的頻繁啟動。蓄能罐根據(jù)自來水給水管網(wǎng)的壓力穩(wěn)定情況配置。
