埃美柯阻流止回閥LH45X概述：

LH45X限流止回(hui)閥(fa)支持水泵(beng)工(gong)作點(dian)在區內工(gong)作，限制水泵(beng)大流量，低效(xiao)率(lv)時(shi)(shi)運行，同時(shi)(shi)微阻緩閉止回(hui)停泵(beng)時(shi)(shi)，關閉無水錘現象；還可以防(fang)水泵(beng)過(guo)載額定(ding)電流燒壞電機，有調節揚(yang)程功能(neng)，限制揚(yang)程可調范圍0.1-0.6MPa，壓力(li)設定(ding)在0.1MPa，可調介質溫度在0-150℃之間(jian)。

埃(ai)美柯(ke)阻流(liu)止回閥LH45X工作原理：

LH45X限流(liu)止回(hui)閥(fa)(fa)安(an)裝(zhuang)于(yu)水(shui)(shui)泵(beng)(beng)出(chu)口(kou)，在(zai)(zai)單泵(beng)(beng)啟動和非設(she)(she)計工(gong)作(zuo)泵(beng)(beng)工(gong)作(zuo)時，對工(gong)作(zuo)泵(beng)(beng)起限制(zhi)流(liu)量(liang)作(zuo)用，使泵(beng)(beng)在(zai)(zai)較狀態下(xia)工(gong)作(zuo)；防電(dian)(dian)動機(ji)在(zai)(zai)水(shui)(shui)泵(beng)(beng)低揚(yang)程(cheng)、大流(liu)量(liang)、低效(xiao)率時，發生過載現(xian)(xian)象；防額定(ding)(ding)(ding)(ding)電(dian)(dian)流(liu)燒電(dian)(dian)機(ji)現(xian)(xian)象的(de)發生，同時起到節能。其限流(liu)原理為(wei)依據水(shui)(shui)泵(beng)(beng)的(de)設(she)(she)計工(gong)況(kuang)點揚(yang)程(cheng)，LH45X限流(liu)止回(hui)閥(fa)(fa)自動檢(jian)測并(bing)控制(zhi)水(shui)(shui)泵(beng)(beng)的(de)實(shi)(shi)際(ji)工(gong)作(zuo)揚(yang)程(cheng)，以(yi)限制(zhi)水(shui)(shui)泵(beng)(beng)的(de)工(gong)作(zuo)流(liu)量(liang)，限制(zhi)電(dian)(dian)機(ji)的(de)負載。LH45X限流(liu)止回(hui)閥(fa)(fa)設(she)(she)定(ding)(ding)(ding)(ding)在(zai)(zai)一個控制(zhi)工(gong)作(zuo)氣(qi)揚(yang)程(cheng)，當水(shui)(shui)泵(beng)(beng)工(gong)作(zuo)揚(yang)程(cheng)低于(yu)控制(zhi)揚(yang)程(cheng)時閥(fa)(fa)門(men)(men)(men)做關閥(fa)(fa)動作(zuo)，使實(shi)(shi)際(ji)工(gong)作(zuo)揚(yang)程(cheng)加(jia)大；當水(shui)(shui)泵(beng)(beng)工(gong)作(zuo)揚(yang)程(cheng)大于(yu)設(she)(she)定(ding)(ding)(ding)(ding)揚(yang)程(cheng)時閥(fa)(fa)門(men)(men)(men)全(quan)開，閥(fa)(fa)門(men)(men)(men)阻力小(xiao)。控制(zhi)氣(qi)揚(yang)程(cheng)的(de)設(she)(she)定(ding)(ding)(ding)(ding)可(ke)以(yi)按電(dian)(dian)機(ji)額定(ding)(ding)(ding)(ding)電(dian)(dian)流(liu)設(she)(she)定(ding)(ding)(ding)(ding)，也(ye)可(ke)以(yi)按工(gong)況(kuang)設(she)(she)定(ding)(ding)(ding)(ding)，該閥(fa)(fa)門(men)(men)(men)工(gong)作(zuo)揚(yang)程(cheng)設(she)(she)定(ding)(ding)(ding)(ding)值可(ke)調，一般出(chu)廠設(she)(she)定(ding)(ding)(ding)(ding)值為(wei)設(she)(she)計工(gong)況(kuang)揚(yang)程(cheng)。
