REXROTH電磁換向閥當天發貨REXROTH電(dian)磁換向(xiang)閥是利用電(dian)磁鐵吸力推(tui)動閥芯來改變閥的工作位(wei)置。由于它可(ke)借助于按鈕開關、行程開關、限位(wei)開關、壓(ya)力繼電(dian)器等發出(chu)的信號進(jin)行控制，所以操作輕便，易于實(shi)現自(zi)動化(hua)，因此應(ying)用廣泛。

REXROTH電磁換(huan)(huan)向閥(fa)閥(fa)芯兩(liang)端(duan)分別接(jie)通(tong)(tong)(tong)控制油(you)(you)(you)(you)口K1和K2。當K1通(tong)(tong)(tong)壓力(li)油(you)(you)(you)(you)時，閥(fa)芯右(you)移，P與A通(tong)(tong)(tong)，B與T通(tong)(tong)(tong);當K2 通(tong)(tong)(tong)壓力(li)油(you)(you)(you)(you)時，閥(fa)芯左(zuo)移，P與B通(tong)(tong)(tong)，A與T通(tong)(tong)(tong);當K1和K2都(dou)不(bu)通(tong)(tong)(tong)壓力(li)油(you)(you)(you)(you)時，閥(fa)芯在兩(liang)端(duan)對(dui)中(zhong)(zhong)彈簧的作用(yong)(yong)下(xia)處于中(zhong)(zhong)位。當對(dui)液動滑閥(fa)換(huan)(huan)向平穩性要求較高時，還(huan)應在滑閥(fa)兩(liang)端(duan)K1、K2控制油(you)(you)(you)(you)路中(zhong)(zhong)加裝阻尼調(diao)(diao)節器下(xia)圖c。阻尼調(diao)(diao)節器由一(yi)(yi)個單(dan)向閥(fa)和一(yi)(yi)個節流(liu)閥(fa)并(bing)聯(lian)組成，單(dan)向閥(fa)用(yong)(yong)來保證(zheng)滑閥(fa)端(duan)面進油(you)(you)(you)(you)暢通(tong)(tong)(tong)，而節流(liu)閥(fa)用(yong)(yong)于滑閥(fa)端(duan)面回(hui)油(you)(you)(you)(you)的節流(liu)，調(diao)(diao)節節流(liu)閥(fa)開(kai)口大小即可調(diao)(diao)整閥(fa)芯的動作時間。

力士樂Rexroth電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)換(huan)(huan)向閥(fa)的工(gong)作(zuo)原理：Rexroth電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)換(huan)(huan)向閥(fa)工(gong)作(zuo)原理是(shi)基本相同的。現(xian)以三位(wei)四通(tong)(tong)O型滑閥(fa)機能的電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)換(huan)(huan)向閥(fa)為(wei)例來(lai)說明。如下(xia)圖(tu)(tu)(tu)閥(fa)體1內有三個環形沉(chen)割(ge)槽(cao)，中(zhong)間(jian)為(wei)進油(you)腔(qiang)(qiang)P，與其相鄰的是(shi)工(gong)作(zuo)油(you)腔(qiang)(qiang)A和(he)B。兩(liang)(liang)端(duan)還有兩(liang)(liang)個互(hu)相連(lian)(lian)通(tong)(tong)的回(hui)油(you)腔(qiang)(qiang)T。閥(fa)芯兩(liang)(liang)端(duan)分別裝有彈(dan)簧座3、復(fu)位(wei)彈(dan)簧4和(he)推桿5，閥(fa)體兩(liang)(liang)端(duan)各(ge)裝一個電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)鐵(tie)。當兩(liang)(liang)端(duan)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)鐵(tie)都斷電(dian)(dian)(dian)時(shi)下(xia)圖(tu)(tu)(tu)a，閥(fa)芯處于中(zhong)間(jian)位(wei)置。此(ci)時(shi)P、A、B、T各(ge)油(you)腔(qiang)(qiang)互(hu)不相通(tong)(tong);當左端(duan)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)鐵(tie)通(tong)(tong)電(dian)(dian)(dian)時(shi)下(xia)圖(tu)(tu)(tu)b，該(gai)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)鐵(tie)吸(xi)合，并推動閥(fa)芯向右(you)移(yi)動，使(shi)P和(he)B連(lian)(lian)通(tong)(tong)，A和(he)T連(lian)(lian)通(tong)(tong)。當其斷電(dian)(dian)(dian)后，右(you)端(duan)復(fu)位(wei)彈(dan)簧的作(zuo)用力可(ke)使(shi)閥(fa)芯回(hui)到中(zhong)間(jian)位(wei)置，恢復(fu)原來(lai)四個油(you)腔(qiang)(qiang)相互(hu)封閉的狀(zhuang)態;當右(you)端(duan)電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)鐵(tie)通(tong)(tong)電(dian)(dian)(dian)時(shi)下(xia)圖(tu)(tu)(tu)c，其銜鐵(tie)將通(tong)(tong)過推桿推動閥(fa)芯向左移(yi)動，P和(he)A相通(tong)(tong)、B和(he)T相通(tong)(tong)。電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)鐵(tie)斷電(dian)(dian)(dian)，閥(fa)芯則在(zai)左彈(dan)簧的作(zuo)用下(xia)回(hui)到中(zhong)間(jian)位(wei)置。

REXROTH電磁換向(xiang)閥(fa)(fa)(fa)利用了閥(fa)(fa)(fa)芯與液(ye)體相對位(wei)置的(de)變化，通過改(gai)變閥(fa)(fa)(fa)門端口(kou)之(zhi)間(jian)的(de)連(lian)接關系，打開和(he)關閉液(ye)體通道，控(kong)制液(ye)體流動換向(xiang)，控(kong)制執(zhi)行機構的(de)啟動停止和(he)運(yun)動換向(xiang)的(de)閥(fa)(fa)(fa)門。

電(dian)磁閥門只能在一定流量和壓力范(fan)圍內正常工作。這(zhe)個工作范(fan)圍的限(xian)制(zhi)稱為整(zheng)改限(xian)制(zhi)。

使(shi)用壽(shou)命(ming)：電(dian)(dian)磁閥的使(shi)用壽(shou)命(ming)主(zhu)要依賴(lai)于電(dian)(dian)磁鐵(tie)(tie)。濕(shi)電(dian)(dian)磁鐵(tie)(tie)的壽(shou)命(ming)比干電(dian)(dian)磁鐵(tie)(tie)長(chang)，DC電(dian)(dian)磁鐵(tie)(tie)的壽(shou)命(ming)比AC電(dian)(dian)磁鐵(tie)(tie)長(chang)。

內(nei)部泄(xie)漏：在不(bu)同的(de)工作位(wei)置和規定的(de)工作壓(ya)力(li)下，高壓(ya)室到低(di)壓(ya)室的(de)泄(xie)漏是內(nei)部泄(xie)漏。內(nei)部泄(xie)漏太(tai)多會降(jiang)低(di)系(xi)統效率，導(dao)致過熱(re)，還(huan)會影響執(zhi)行器的(de)正常運行。換(huan)向頻(pin)率：換(huan)向頻(pin)率是單(dan)位(wei)時間內(nei)閥門允許的(de)切(qie)換(huan)次(ci)(ci)數。目前，單(dan)個電磁鐵電磁閥的(de)整流頻(pin)率一般為(wei)60次(ci)(ci)/分(fen)鐘。
