力士樂電磁閥按原理分為: 直(zhi)動式、分布直(zhi)動式、先導(dao)式三大類;按結(jie)構分為(wei)膜片式電磁閥和活塞式電磁閥兩類。 力士樂電磁閥工作原理: 電(dian)磁閥(fa)里有密閉的(de)(de)(de)腔,在的(de)(de)(de)不(bu)(bu)同位置開有通孔(kong)(kong),每個孔(kong)(kong)都通向不(bu)(bu)同的(de)(de)(de)油(you)(you)管,腔中間是(shi)閥(fa),兩面是(shi)兩塊電(dian)磁鐵(tie),哪面的(de)(de)(de)磁鐵(tie)線圈(quan)通電(dian)閥(fa)體就(jiu)會被吸引到哪邊,通過控(kong)(kong)制(zhi)閥(fa)體的(de)(de)(de)移(yi)動(dong)(dong)(dong)來檔(dang)住或漏出不(bu)(bu)同的(de)(de)(de)排油(you)(you)的(de)(de)(de)孔(kong)(kong),而進油(you)(you)孔(kong)(kong)是(shi)常開的(de)(de)(de),液(ye)壓油(you)(you)就(jiu)會進入不(bu)(bu)同的(de)(de)(de)排油(you)(you)管,然后通過油(you)(you)的(de)(de)(de)壓力來推動(dong)(dong)(dong)油(you)(you)缸的(de)(de)(de)活(huo)塞(sai),活(huo)塞(sai)又帶(dai)動(dong)(dong)(dong)活(huo)塞(sai)桿,活(huo)塞(sai)竿帶(dai)動(dong)(dong)(dong)機械裝(zhuang)置動(dong)(dong)(dong)。這樣通過控(kong)(kong)制(zhi)電(dian)磁鐵(tie)的(de)(de)(de)電(dian)流就(jiu)控(kong)(kong)制(zhi)了機械運(yun)動(dong)(dong)(dong)。 【1】力士樂直動式電磁閥工作原理: 通電(dian)(dian)時,電(dian)(dian)磁線(xian)圈(quan)產生(sheng)電(dian)(dian)磁力把關閉件從(cong)閥座(zuo)上提起,閥門打(da)開;斷電(dian)(dian)時,電(dian)(dian)磁力消失,彈(dan)簧把關閉件壓在閥座(zuo)上,閥門關閉。 【2】力士樂分(fen)布(bu)直(zhi)動式(shi)電磁閥工作原(yuan)理: 它(ta)是(shi)一種直動(dong)式(shi)和先(xian)(xian)導(dao)(dao)(dao)式(shi)相結(jie)合的(de)原理。常閉式(shi)---當(dang)(dang)入(ru)口(kou)與(yu)(yu)出(chu)口(kou)沒有(you)壓差(cha)時,通(tong)電(dian)(dian)后(hou)電(dian)(dian)磁(ci)力(li)直接(jie)打開(kai)先(xian)(xian)導(dao)(dao)(dao)孔(kong)連(lian)接(jie)主閥(fa)活塞(sai)(sai)依次向(xiang)上提起,閥(fa)門打開(kai);當(dang)(dang)入(ru)口(kou)與(yu)(yu)出(chu)口(kou)達到啟動(dong)壓差(cha)時,通(tong)電(dian)(dian)后(hou),電(dian)(dian)磁(ci)力(li)先(xian)(xian)打開(kai)先(xian)(xian)導(dao)(dao)(dao)孔(kong),主閥(fa)活塞(sai)(sai)上腔壓力(li)下(xia)降,從而利用壓差(cha)和電(dian)(dian)磁(ci)力(li)拉動(dong)主活塞(sai)(sai),閥(fa)口(kou)打開(kai);斷電(dian)(dian)時,靠彈簧復位(wei)關(guan)閉先(xian)(xian)導(dao)(dao)(dao)孔(kong),主活塞(sai)(sai)上腔增(zeng)壓,推動(dong)主活塞(sai)(sai)向(xiang)下(xia)移動(dong),閥(fa)關(guan)閉。常開(kai)式(shi)與(yu)(yu)常閉式(shi)相反(fan)。 【3】力士(shi)樂先導式(shi)電磁閥(fa)工作原(yuan)理(li): 常(chang)閉(bi)式---通電時(shi),電磁力吸合(he)先導孔(kong)閥芯,先導孔(kong)打開,主(zhu)(zhu)閥活(huo)(huo)塞上(shang)腔(qiang)壓(ya)(ya)力下(xia)(xia)降(jiang),在主(zhu)(zhu)活(huo)(huo)塞上(shang)腔(qiang)和(he)下(xia)(xia)腔(qiang)形(xing)成上(shang)低下(xia)(xia)高(gao)的(de)壓(ya)(ya)力,這樣下(xia)(xia)腔(qiang)壓(ya)(ya)力推動(dong)主(zhu)(zhu)活(huo)(huo)塞打開閥門;斷電時(shi),彈簧力復位(wei)關(guan)閉(bi)先導孔(kong),主(zhu)(zhu)活(huo)(huo)塞上(shang)腔(qiang)增壓(ya)(ya),在主(zhu)(zhu)活(huo)(huo)塞上(shang)腔(qiang)和(he)下(xia)(xia)腔(qiang)形(xing)成上(shang)高(gao)下(xia)(xia)低的(de)壓(ya)(ya)力,介質壓(ya)(ya)力和(he)彈簧力推動(dong)主(zhu)(zhu)活(huo)(huo)塞,閥關(guan)閉(bi)。常(chang)開式與常(chang)閉(bi)式相反。 【4】力(li)士樂膜片式電磁閥(fa)工作原理: 通(tong)(tong)電(dian)時,電(dian)磁力(li)(li)把先導孔打開(kai),上腔(qiang)室(shi)(shi)壓(ya)(ya)力(li)(li)迅(xun)速下降(jiang),在關閉(bi)(bi)件周圍(wei)形成上低下高的(de)(de)壓(ya)(ya)差(cha),流體(ti)壓(ya)(ya)力(li)(li)推動(dong)關閉(bi)(bi)件向上移動(dong),閥(fa)門打開(kai);斷(duan)電(dian)時,彈簧力(li)(li)把先導孔關閉(bi)(bi),入(ru)口壓(ya)(ya)力(li)(li)通(tong)(tong)過旁通(tong)(tong)孔迅(xun)速腔(qiang)室(shi)(shi)在關閥(fa)件周圍(wei)形成下低上高的(de)(de)壓(ya)(ya)差(cha),流體(ti)壓(ya)(ya)力(li)(li)推動(dong)關閉(bi)(bi)件向下移動(dong),關閉(bi)(bi)閥(fa)門。 【5】力士樂活塞(sai)式電磁閥工作原理(li): 線(xian)圈通(tong)電后由于吸力作(zuo)(zuo)用(yong),動鐵(tie)芯下移,把副(fu)(fu)閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)塞(sai)壓下,副(fu)(fu)閥(fa)(fa)(fa)(fa)(fa)(fa)關(guan)閉,主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯內壓力上(shang)升,當壓力升到(dao)一定值時(shi),主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯的(de)(de)上(shang)下壓差一樣,由于電磁力作(zuo)(zuo)用(yong),動鐵(tie)芯失去(qu)主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯下,壓緊主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)座(zuo),閥(fa)(fa)(fa)(fa)(fa)(fa)門關(guan)閉。線(xian)圈斷電時(shi),電磁吸力為零(ling),副(fu)(fu)閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)塞(sai)和支(zhi)鐵(tie)芯由于彈簧作(zuo)(zuo)用(yong)向上(shang)提起(qi),副(fu)(fu)閥(fa)(fa)(fa)(fa)(fa)(fa)打(da)開,主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯上(shang)的(de)(de)流體(ti)經副(fu)(fu)閥(fa)(fa)(fa)(fa)(fa)(fa)流走,減(jian)少了作(zuo)(zuo)用(yong)在主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯上(shang)的(de)(de)壓力,當主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯上(shang)的(de)(de)壓力減(jian)少到(dao)一定值時(shi),利用(yong)壓差把主閥(fa)(fa)(fa)(fa)(fa)(fa)閥(fa)(fa)(fa)(fa)(fa)(fa)杯推(tui)起(qi),主閥(fa)(fa)(fa)(fa)(fa)(fa)打(da)開,介質流通(tong)。
