力士樂(le)(le)M-3SEW電磁(ci)閥(fa)概述(shu)：     力士樂(le)(le)M-SEW型方(fang)向(xiang)(xiang)閥(fa)是電磁(ci)截(jie)止式方(fang)向(xiang)(xiang)閥(fa)，用於控制油(you)液的(de)流動、停止和方(fang)向(xiang)(xiang)。力士樂(le)(le)M-SEW 型方(fang)向(xiang)(xiang)閥(fa)其組成主要包括(kuo)閥(fa)體 (1)、電磁(ci)鐵 (2)，經過硬化處理(li)的(de)閥(fa)系統 (3)，以及作為關閉件的(de)球 (4)。     

力(li)士樂M-SEW 型方向閥(fa)基本原(yuan)理(li)：     在(zai)初始(shi)位(wei)置，閥(fa)芯 (4) 被彈(dan)簧(huang) (9) 推向閥(fa)座(zuo)(zuo)，在(zai)切換位(wei)置，電(dian)磁鐵 (2) 將其推向閥(fa)座(zuo)(zuo)。電(dian)磁鐵 (2) 的力(li)經過角狀(zhuang)杠桿 (6) 和球(qiu) (7) 作用(yong)於兩面密(mi)封的操(cao)作推桿 (8)。 在(zai)兩個(ge)密(mi)封元(yuan)件之間的閥(fa)腔與P口連通。這樣，閥(fa)系統 (3) 的壓(ya)力(li)相(xiang)對(dui)於操(cao)作力(li) (電(dian)磁鐵或彈(dan)簧(huang))，處於平(ping)(ping)衡狀(zhuang)態 (即推桿、閥(fa)芯軸系處於軸向液(ye)壓(ya)力(li)平(ping)(ping)衡狀(zhuang)態)。這種閥(fa)因此可(ke)在(zai)壓(ya)力(li)高達(da) 630bar 條件下使用(yong)。     

力士樂(le)M-SEW型方(fang)向閥(fa)選型需要哪些(xie)參數呢？    德國力士樂(le)M-3SEW電(dian)磁閥(fa)資料(liao)     力士樂(le)M-3SEW電(dian)磁閥(fa)在2位3通(tong)方(fang)向提升閥(fa)的(de)下方(fang)連接一個迭(die)加板(ban)，即(ji)附加-1板(ban)，力士樂(le)M-3SEW電(dian)磁閥(fa)可用作2位4通(tong)截止式方(fang)向閥(fa)。在使用過(guo)程中力士樂(le)M-3SEW電(dian)磁閥(fa)的(de)運行(xing)過(guo)程是怎么樣的(de)呢？     

力士樂M-3SEW電磁閥初始位置：     主閥沒有(you)運作。彈簧(huang) (9) 使(shi)閥芯 (4.1) 保持在閥座  (11)上。油(you)(you)(you)口(kou)P關閉，油(you)(you)(you)口(kou)A與油(you)(you)(you)口(kou)T相連(lian)通。此外，從A到控(kong)制活塞(12) 的(de)大面積上有(you)一條控(kong)制管路，可向油(you)(you)(you)箱卸荷。經過油(you)(you)(you)口(kou)P產生的(de)壓(ya)力這時(shi)將球 (13) 推向閥座 (14)。所以(yi)油(you)(you)(you)口(kou)P與油(you)(you)(you)口(kou)B 連(lian)通，A 和 T 連(lian)通。     

力士樂M-3SEW電磁(ci)閥過(guo)渡位(wei)置：     當主(zhu)閥工作時，球 (4.2) 被(bei)推動而克服彈簧力 (9)，然後壓在閥座 (15) 上。
