力士樂Rexroth流量控制閥2FRM6B36-3X/6QRV定壓溢流作用在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí)，會(huì)使流量需求減小。此時(shí)溢流閥開啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動(dòng)開啟）。

電磁閥故障與排除
一、電磁閥通電后不工作
檢查電源接線是否不良→重新接線和接插件的連接
檢查電源電壓是否在±工作范圍-→調(diào)致正常位置范圍
線圈是否脫焊→重新焊接
線圈短路→更換線圈
工作壓差是否不合適→調(diào)整壓差→或更換相稱的電磁閥
流體溫度過高→更換相稱的電磁閥
有雜質(zhì)使電磁閥的主閥芯和動(dòng)鐵芯卡死→進(jìn)行清洗，如有密封損壞應(yīng)更換密封并安裝過濾器
液體粘度太大，頻率太高和壽命已到→更換產(chǎn)品
二、電磁閥不能關(guān)閉
主閥芯或鐵動(dòng)芯的密封件已損壞→更換密封件
流體溫度、粘度是否過高→更換對(duì)口的電磁閥
有雜質(zhì)進(jìn)入電磁閥產(chǎn)閥芯或動(dòng)鐵芯→進(jìn)行清洗
彈簧壽命已到或變形→更換
節(jié)流孔平衡孔堵塞→及時(shí)清洗
工作頻率太高或壽命已到→改選產(chǎn)品或更新產(chǎn)品
三、其它情況
內(nèi)泄漏→檢查密封件是否損壞，彈簧是否裝配不良
外泄漏→連接處松動(dòng)或密封件已壞→緊螺絲或更換密封件
通電時(shí)有噪聲→頭子上堅(jiān)固件松動(dòng)，擰緊。電壓波動(dòng)不在允許范圍內(nèi)，調(diào)整好電壓。鐵芯吸合面雜質(zhì)或不平，及時(shí)清洗或更換。

2FRM型調(diào)速閥是兩通的流量控制閥，上海韋米機(jī)電銷售此閥是由減壓閥和節(jié)流閥串聯(lián)構(gòu)成的。油流進(jìn)入調(diào)速閥后，先經(jīng)閥減壓，再由節(jié)流閥節(jié)流。由于減壓閥對(duì)節(jié)流閥進(jìn)行了壓力補(bǔ)償，所以調(diào)速閥的流量不受負(fù)載變化的影響。同時(shí)節(jié)流窗口設(shè)計(jì)成薄刃狀，流量受溫度變化很小。調(diào)速閥與單向閥并聯(lián)時(shí)，油流能反向回流。Z4S型整在調(diào)速閥下，可以穩(wěn)定通過調(diào)速閥兩個(gè)方向的流量
