给水(shui)(shui)(shui)设备在(zai)结构以及控(kong)制方式(shi)上(shang)多种多样,给水(shui)(shui)(shui)设备在(zai)结构上(shang)较多采用(yong)(yong)“水(shui)(shui)(shui)泵组+变(bian)频(pin)(pin)电控(kong)柜”的(de)(de)形(xing)式(shi)。用(yong)(yong)水(shui)(shui)(shui)定(ding)时定(ding)量(liang)设备供(gong)应不同,生(sheng)活用(yong)(yong)水(shui)(shui)(shui)量(liang)变(bian)化曲线较大(da),而且具有明显的(de)(de)时间特性(xing),因此,生(sheng)活给水(shui)(shui)(shui)设备应具有“多用(yong)(yong)水(shui)(shui)(shui)、多耗(hao)电;少(shao)用(yong)(yong)水(shui)(shui)(shui)、少(shao)耗(hao)电”的(de)(de)节能特点。气压(ya)罐是水(shui)(shui)(shui)泵可以进入睡眠的(de)(de)前提条件,利用(yong)(yong)水(shui)(shui)(shui)的(de)(de)压(ya)缩(suo)(suo)性(xing)极小的(de)(de)性(xing)质,用(yong)(yong)外(wai)力将水(shui)(shui)(shui)储存在(zai)罐内,气体受到压(ya)缩(suo)(suo)压(ya)力升高,当外(wai)力消失(shi)压(ya)缩(suo)(suo)气体膨(peng)胀(zhang)可将水(shui)(shui)(shui)排除(chu)。由(you)于(yu)水(shui)(shui)(shui)的(de)(de)压(ya)缩(suo)(suo)比远(yuan)远(yuan)小于(yu)气体,当管网有小流量(liang)的(de)(de)泄漏(lou)可造(zao)成压(ya)力大(da)幅度的(de)(de)下降,可使水(shui)(shui)(shui)泵频(pin)(pin)繁(fan)启动。如(ru)工频(pin)(pin)泵直接(jie)向用(yong)(yong)户供(gong)水(shui)(shui)(shui),就必需配备气压(ya)罐,缓解水(shui)(shui)(shui)泵频(pin)(pin)繁(fan)启动。

  选(xuan)购

  给水(shui)(shui)设备(bei)(bei)在结(jie)构(gou)以及控(kong)制方式上(shang)多种多样(yang),给水(shui)(shui)设备(bei)(bei)在结(jie)构(gou)上(shang)较多采用(yong)“水(shui)(shui)泵(beng)组+变(bian)频(pin)电(dian)控(kong)柜”的(de)(de)(de)(de)形式。一般来说,和生产(chan)用(yong)水(shui)(shui)定时定量供(gong)应不同,生活(huo)用(yong)水(shui)(shui)量变(bian)化曲线(xian)较大,而且具有(you)(you)明显的(de)(de)(de)(de)时间特性,因此,生活(huo)给水(shui)(shui)设备(bei)(bei)应具有(you)(you)“多用(yong)水(shui)(shui)、多耗电(dian);少用(yong)水(shui)(shui)、少耗电(dian)”的(de)(de)(de)(de)节(jie)能特点。气压(ya)(ya)(ya)罐(guan)(guan)是水(shui)(shui)泵(beng)可(ke)以进(jin)入睡眠的(de)(de)(de)(de)前提(ti)条(tiao)件,利用(yong)水(shui)(shui)的(de)(de)(de)(de)压(ya)(ya)(ya)缩性极小的(de)(de)(de)(de)性质,用(yong)外力将水(shui)(shui)储存(cun)在罐(guan)(guan)内(nei),气体受到压(ya)(ya)(ya)缩压(ya)(ya)(ya)力升高(gao),当(dang)(dang)外力消失压(ya)(ya)(ya)缩气体膨胀可(ke)将水(shui)(shui)排除。由(you)于(yu)水(shui)(shui)的(de)(de)(de)(de)压(ya)(ya)(ya)缩比远远小于(yu)气体,当(dang)(dang)管网有(you)(you)小流量的(de)(de)(de)(de)泄漏可(ke)造成压(ya)(ya)(ya)力大幅(fu)度(du)的(de)(de)(de)(de)下降,可(ke)使水(shui)(shui)泵(beng)频(pin)繁(fan)启(qi)动。如工频(pin)泵(beng)直接(jie)向用(yong)户(hu)供(gong)水(shui)(shui),就(jiu)必需配(pei)备(bei)(bei)气压(ya)(ya)(ya)罐(guan)(guan),缓解水(shui)(shui)泵(beng)频(pin)繁(fan)启(qi)动。
