變(bian)(bian)頻(pin)供(gong)水(shui)(shui)設備(bei)是(shi)處理水(shui)(shui)壓(ya)(ya)缺(que)乏，變(bian)(bian)頻(pin)加壓(ya)(ya)供(gong)水(shui)(shui)的設備(bei)類型，水(shui)(shui)泵是(shi)成套變(bian)(bian)頻(pin)供(gong)水(shui)(shui)設備(bei)中(zhong)重要組(zu)成局部(bu)，華振(zhen)運(yun)用變(bian)(bian)頻(pin)調速技術，使其(qi)生活供(gong)水(shui)(shui)愈加節能、環保、自(zi)動運(yun)轉(zhuan)。

如何處理變頻供水設備水泵低效運轉：

　　1.樹立(li)用水負荷模型

　　在(zai)變(bian)(bian)頻(pin)(pin)驅動供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)技術方(fang)(fang)面(mian)，國內外很(hen)多學者曾(ceng)經有了深(shen)化的(de)(de)(de)研(yan)討(tao)(tao)，但(dan)對(dui)二次供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)量(liang)(liang)、用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)范(fan)圍(wei)等(deng)方(fang)(fang)面(mian)的(de)(de)(de)研(yan)討(tao)(tao)還比擬少，因而(er)，要加大(da)對(dui)用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)特(te)性的(de)(de)(de)研(yan)討(tao)(tao)力度。由(you)于變(bian)(bian)頻(pin)(pin)供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)泵的(de)(de)(de)選(xuan)(xuan)配(pei)對(dui)其(qi)運轉效率(lv)有直接影(ying)響(xiang)，而(er)用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)量(liang)(liang)、用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)變(bian)(bian)化規律、用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)范(fan)圍(wei)等(deng)對(dui)變(bian)(bian)頻(pin)(pin)供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)泵的(de)(de)(de)選(xuan)(xuan)配(pei)有很(hen)大(da)的(de)(de)(de)影(ying)響(xiang)，因而(er)，在(zai)迸行二次供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)設計時，要針對(dui)用(yong)(yong)(yong)戶(hu)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)量(liang)(liang)、用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)變(bian)(bian)化規律、用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)范(fan)圍(wei)等(deng)停止細致(zhi)調查研(yan)討(tao)(tao)，并樹(shu)立相(xiang)應的(de)(de)(de)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)負荷模(mo)型，從(cong)而(er)為(wei)變(bian)(bian)頻(pin)(pin)供(gong)(gong)(gong)水(shui)(shui)(shui)(shui)泵的(de)(de)(de)選(xuan)(xuan)配(pei)提供(gong)(gong)(gong)根據。

　　2.開發新(xin)型控制系(xi)統

　　對控(kong)制(zhi)(zhi)(zhi)系統不合理惹起的(de)變(bian)(bian)(bian)頻(pin)水(shui)(shui)泵(beng)低效(xiao)(xiao)(xiao)運轉(zhuan)現象(xiang)，首先要(yao)改動(dong)水(shui)(shui)泵(beng)出口(kou)壓(ya)力恒定低效(xiao)(xiao)(xiao)控(kong)制(zhi)(zhi)(zhi)形式(shi)，其控(kong)制(zhi)(zhi)(zhi)方式(shi)改動(dong)成(cheng)水(shui)(shui)泵(beng)出口(kou)變(bian)(bian)(bian)壓(ya)變(bian)(bian)(bian)流量控(kong)制(zhi)(zhi)(zhi)，并將變(bian)(bian)(bian)頻(pin)水(shui)(shui)泵(beng)組控(kong)制(zhi)(zhi)(zhi)形式(shi)改動(dong)成(cheng)單變(bian)(bian)(bian)頻(pin)控(kong)制(zhi)(zhi)(zhi)方式(shi)，從而進步變(bian)(bian)(bian)頻(pin)水(shui)(shui)泵(beng)高效(xiao)(xiao)(xiao)運轉(zhuan)范(fan)圍。在肯(ken)定二(er)次(ci)供(gong)水(shui)(shui)變(bian)(bian)(bian)頻(pin)水(shui)(shui)泵(beng)控(kong)制(zhi)(zhi)(zhi)方式(shi)時，要(yao)對水(shui)(shui)泵(beng)效(xiao)(xiao)(xiao)率(lv)(lv)調(diao)速極限(xian)要(yao)素(su)停(ting)止剖(pou)析，從而為水(shui)(shui)泵(beng)全(quan)流量效(xiao)(xiao)(xiao)率(lv)(lv)運轉(zhuan)提供(gong)保證(zheng)。關于管網變(bian)(bian)(bian)化(hua)要(yao)素(su)多、用水(shui)(shui)變(bian)(bian)(bian)化(hua)大的(de)建(jian)筑二(er)次(ci)供(gong)水(shui)(shui)，要(yao)對水(shui)(shui)泵(beng)效(xiao)(xiao)(xiao)率(lv)(lv)調(diao)速極限(xian)、管網特性、控(kong)制(zhi)(zhi)(zhi)戰略等停(ting)止全(quan)面(mian)剖(pou)析，推行(xing)控(kong)制(zhi)(zhi)(zhi)系統的(de)工程(cheng)化(hua)應(ying)用，從而確保二(er)次(ci)供(gong)水(shui)(shui)變(bian)(bian)(bian)頻(pin)水(shui)(shui)泵(beng)的(de)高效(xiao)(xiao)(xiao)運轉(zhuan)。

　　3.降低變頻供水設備內部損耗(hao)

　　關于二次供(gong)水(shui)變(bian)頻水(shui)泵設(she)備(bei)，要注(zhu)重降(jiang)低(di)變(bian)頻供(gong)水(shui)設(she)備(bei)內(nei)部(bu)損耗(hao)的(de)(de)問題，從而(er)有效地進步(bu)二次供(gong)水(shui)變(bian)頻水(shui)栗運轉(zhuan)效率(lv)。變(bian)頻供(gong)水(shui)泵消費(fei)廠家在停止設(she)備(bei)消費(fei)時，要留意增強(qiang)產質量量控制(zhi)，依據(ju)設(she)備(bei)的(de)(de)實踐狀況(kuang)，選購配(pei)套的(de)(de)控制(zhi)元(yuan)件(jian)、閥件(jian)等器件(jian)，從而(er)進步(bu)整裝設(she)備(bei)的(de)(de)運轉(zhuan)效率(lv)。

　　變頻供水設(she)備(bei)水泵低效(xiao)運轉的(de)緣由：

　　1.水泵選擇不(bu)合(he)理

　　從理(li)(li)論上(shang)看，變(bian)(bian)(bian)頻供(gong)(gong)(gong)水(shui)(shui)(shui)設備的(de)(de)(de)水(shui)(shui)(shui)泵(beng)(beng)其能(neng)耗(hao)(hao)應該比擬(ni)(ni)小(xiao)，但在(zai)(zai)實踐應用(yong)中(zhong)(zhong)發現(xian)，變(bian)(bian)(bian)頻供(gong)(gong)(gong)水(shui)(shui)(shui)系(xi)統(tong)(tong)的(de)(de)(de)能(neng)耗(hao)(hao)很(hen)(hen)高，以至比水(shui)(shui)(shui)泵(beng)(beng)-水(shui)(shui)(shui)箱結合供(gong)(gong)(gong)水(shui)(shui)(shui)方式能(neng)耗(hao)(hao)的(de)(de)(de)2倍都高，這闡明變(bian)(bian)(bian)頻驅動(dong)供(gong)(gong)(gong)水(shui)(shui)(shui)系(xi)統(tong)(tong)并不(bu)節能(neng)。變(bian)(bian)(bian)頻水(shui)(shui)(shui)泵(beng)(beng)供(gong)(gong)(gong)水(shui)(shui)(shui)技(ji)術(shu)固然在(zai)(zai)我(wo)國建筑二(er)次供(gong)(gong)(gong)水(shui)(shui)(shui)中(zhong)(zhong)的(de)(de)(de)應用(yong)時間比擬(ni)(ni)長，但很(hen)(hen)多技(ji)術(shu)人(ren)(ren)員對變(bian)(bian)(bian)頻供(gong)(gong)(gong)水(shui)(shui)(shui)系(xi)統(tong)(tong)的(de)(de)(de)認識還(huan)不(bu)全面，錯誤的(de)(de)(de)以為采用(yong)變(bian)(bian)(bian)頻技(ji)術(shu)就(jiu)是減少能(neng)耗(hao)(hao)，在(zai)(zai)停止二(er)次供(gong)(gong)(gong)水(shui)(shui)(shui)設計(ji)(ji)時，隨意的(de)(de)(de)選(xuan)(xuan)(xuan)擇(ze)水(shui)(shui)(shui)泵(beng)(beng)，從而招致水(shui)(shui)(shui)泵(beng)(beng)選(xuan)(xuan)(xuan)擇(ze)不(bu)合理(li)(li)，這就(jiu)對二(er)次供(gong)(gong)(gong)水(shui)(shui)(shui)變(bian)(bian)(bian)頻水(shui)(shui)(shui)泵(beng)(beng)運轉(zhuan)效率形(xing)成很(hen)(hen)大的(de)(de)(de)影(ying)響。在(zai)(zai)供(gong)(gong)(gong)水(shui)(shui)(shui)系(xi)統(tong)(tong)設計(ji)(ji)選(xuan)(xuan)(xuan)擇(ze)水(shui)(shui)(shui)泵(beng)(beng)時，設計(ji)(ji)人(ren)(ren)員經常會依(yi)照供(gong)(gong)(gong)水(shui)(shui)(shui)系(xi)統(tong)(tong)最(zui)大設計(ji)(ji)流量(liang)停止組(zu)合，而在(zai)(zai)工(gong)程(cheng)上(shang)有(you)一(yi)用(yong)一(yi)備、二(er)用(yong)一(yi)備、三用(yong)一(yi)備、四(si)用(yong)一(yi)備等狀況，流量(liang)匹配有(you)25%+25%+25%+25%、10%+30%+30%+30%、40%+40%+40%、50%+50%等狀況，設計(ji)(ji)人(ren)(ren)員在(zai)(zai)設計(ji)(ji)過(guo)程(cheng)當選(xuan)(xuan)(xuan)擇(ze)比擬(ni)(ni)普遍，檢查(cha)人(ren)(ren)員很(hen)(hen)難判(pan)別(bie)其泵(beng)(beng)組(zu)設計(ji)(ji)選(xuan)(xuan)(xuan)配能(neng)否合理(li)(li)。

　　2.控制形式不合理

　　關于(yu)(yu)變(bian)(bian)(bian)(bian)頻調(diao)(diao)速水泵(beng)(beng)(beng)(beng)(beng)，其控(kong)(kong)(kong)(kong)制形(xing)式(shi)有變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)控(kong)(kong)(kong)(kong)制和(he)(he)恒壓(ya)(ya)(ya)(ya)控(kong)(kong)(kong)(kong)制兩種(zhong)狀(zhuang)況(kuang)，其中(zhong)變(bian)(bian)(bian)(bian)壓(ya)(ya)(ya)(ya)控(kong)(kong)(kong)(kong)制是(shi)依據(ju)變(bian)(bian)(bian)(bian)頻水泵(beng)(beng)(beng)(beng)(beng)出(chu)口(kou)處(chu)的(de)(de)流量計(ji)(ji)和(he)(he)壓(ya)(ya)(ya)(ya)力傳感(gan)器(qi)，剖析(xi)管網用(yong)水實踐需(xu)(xu)求(qiu)，然后(hou)對(dui)水泵(beng)(beng)(beng)(beng)(beng)的(de)(de)轉(zhuan)速停止調(diao)(diao)整，從而(er)滿(man)足用(yong)戶的(de)(de)用(yong)水需(xu)(xu)求(qiu);恒壓(ya)(ya)(ya)(ya)控(kong)(kong)(kong)(kong)制是(shi)在管網末(mo)端(duan)或者水泵(beng)(beng)(beng)(beng)(beng)出(chu)口(kou)處(chu)裝(zhuang)置(zhi)壓(ya)(ya)(ya)(ya)力傳感(gan)器(qi)，然后(hou)設(she)定一個恒定的(de)(de)水壓(ya)(ya)(ya)(ya)，對(dui)電機轉(zhuan)速、水泵(beng)(beng)(beng)(beng)(beng)轉(zhuan)速、運轉(zhuan)水泵(beng)(beng)(beng)(beng)(beng)的(de)(de)數量等停止調(diao)(diao)整，從而(er)滿(man)足用(yong)戶用(yong)水需(xu)(xu)求(qiu)，依據(ju)壓(ya)(ya)(ya)(ya)力傳感(gan)器(qi)的(de)(de)裝(zhuang)置(zhi)位置(zhi)，能夠將恒壓(ya)(ya)(ya)(ya)控(kong)(kong)(kong)(kong)制分為管網末(mo)端(duan)壓(ya)(ya)(ya)(ya)力恒定控(kong)(kong)(kong)(kong)制和(he)(he)水泵(beng)(beng)(beng)(beng)(beng)出(chu)口(kou)壓(ya)(ya)(ya)(ya)力恒定控(kong)(kong)(kong)(kong)制兩種(zhong)狀(zhuang)況(kuang)。在肯(ken)定變(bian)(bian)(bian)(bian)頻調(diao)(diao)速水泵(beng)(beng)(beng)(beng)(beng)控(kong)(kong)(kong)(kong)制形(xing)式(shi)時(shi)，設(she)計(ji)(ji)人員經常會疏忽水泵(beng)(beng)(beng)(beng)(beng)效率(lv)調(diao)(diao)速極限及管網水力特性，從而(er)形(xing)成能耗糜費(fei)，如用(yong)水量小(xiao)于(yu)(yu)最大設(she)計(ji)(ji)流量時(shi)，管網實踐需(xu)(xu)求(qiu)壓(ya)(ya)(ya)(ya)力必然小(xiao)于(yu)(yu)供水壓(ya)(ya)(ya)(ya)力，這時(shi)多余的(de)(de)水頭(tou)壓(ya)(ya)(ya)(ya)力就會形(xing)成糜費(fei)。

　　3.供水(shui)系統內部部分水(shui)損比(bi)擬大(da)

　　近年來，隨著我國建筑行業的快速開展，二次供水范圍越來越大，變頻供水設備的(de)開展也越來越快(kuai)，目前(qian)，很(hen)(hen)多(duo)(duo)變頻供水系統是由廠(chang)家(jia)直接(jie)提(ti)供的(de)，由于變頻供水系統具有(you)集成(cheng)組(zu)裝的(de)特性，很(hen)(hen)多(duo)(duo)廠(chang)家(jia)都是自主研討(tao)主要構(gou)件(jian)，然后在(zai)市(shi)場上采(cai)購控制元(yuan)件(jian)、閥件(jian)等器(qi)件(jian)，廠(chang)家(jia)在(zai)選購這些器(qi)件(jian)時，經常會(hui)疏忽(hu)閥件(jian)的(de)部分損失，這就會(hui)對水泵運(yun)轉效率形成(cheng)很(hen)(hen)大(da)的(de)影響。
