力士樂比例溢流閥0811402016 DBETX-10/315G24-8NZ4M

比例溢流閥工作原理是：比例溢流閥通過彈簧力的大小改變溢流壓力大大小變化，比例電磁鐵作用在彈簧上的力可以按比例調(diào)整，所以就輸入信號變化比例溢流閥的壓力也會變化。

普通溢流閥與比例溢流閥一樣，都有一個閥芯，閥芯的一端是液壓油產(chǎn)生的壓力，另一端是機(jī)械力。普通溢流閥通過調(diào)節(jié)彈簧力，來調(diào)整液壓壓力。而比例溢流閥是電磁鐵直接產(chǎn)生推力，作用在閥芯上，電磁鐵上的輸入電壓可以在0-24伏之間變化，產(chǎn)生的推力就隨之變化，從而得到連續(xù)變化的液壓壓力。

因為比例電磁鐵的推力不大，所以直動式比例溢流閥的流量很小，壓力70兆帕?xí)r，流量只有1升/分鐘左右。需要大流量比例閥的時候，要把這個比例閥做先導(dǎo)閥，還要配一個大通徑的溢流閥

由于各種原因，空氣被吸入油液中，或者在油液壓力低于大氣壓時，溶解在油液中的部分空氣就會析出形成氣泡，這些氣泡在低壓區(qū)時體積較 大，當(dāng)隨油液流到高壓區(qū)時，受到壓縮，體積突然變小或氣泡消失；反之，如在高壓區(qū)時體積本來較小，而當(dāng)流到低壓區(qū)時，體積突然增 大，油中氣泡體積這種急速改變的現(xiàn)象。

比例溢流閥的故障及其解決方法
比例滋流潤是能夠與電氣信號成比例的控制壓力的閥。它主要是由作為電—力轉(zhuǎn)換器的比例電磁鐵、力矩馬達(dá)、力馬達(dá)和作為力—液壓轉(zhuǎn)換器的先導(dǎo)閥。噴嘴擋板閥等組成。這里主要對比例電磁鐵和先導(dǎo)闊組成的比例先導(dǎo)閥的故障進(jìn)行分析。而對比例控制平衡活塞式滋流閥不做敘述。(關(guān)于比例控制平衡活塞式溢流閥的故障分析，與前面有關(guān)普通平衡活塞式濫流閥的故障分析基本一致)。
如果控制壓力發(fā)生故障，那么先用電流表檢查電流值。斷定究竟是包括電磁鐵的控制電路有問題，還是平衡活塞式閥有問題，然后再根據(jù)具體情況體對待。下面給出各種故障現(xiàn)象，然后分析產(chǎn)生故障的原因和解決方法。
(一)雖然流過電磁鐵的電流為額定值，但壓力完全上不去，或得不到所需壓力。
原因1，比例先導(dǎo)閥的先導(dǎo)閥口沽上大粒污垢，保持一個大開口，因此壓力上不去。解決方法是拆開清洗。
原因2，進(jìn)行搖控的場合，一般平衡活塞式溢流閥的調(diào)壓手輪放松時壓力就降低，而整體式比例控制平衡活塞式溢流閥，假如安全閥調(diào)整螺絲放松，也同樣會降低設(shè)定壓力。解決方法是將該壓力設(shè)定到超過壓力24kgf/cm2左右，使其經(jīng)常保持關(guān)閉狀態(tài)。若壓力設(shè)定過低，則接近工作壓力時，先導(dǎo)流量就會同時從安全閥和比例微導(dǎo)閥兩處流出，得不到所需壓力。
(二)流過電磁鐵的電流已經(jīng)過大，但壓力還是不上，或得不到所要求的壓力。
原因1,檢查電磁鐵線圈電阻，若遠(yuǎn)小于規(guī)定值，那是電磁鐵線圈內(nèi)部短路了。
原因2，電磁鐵線圈電阻正常，此時是接放大器的連線短路。這兩種原因的解決方躊是更換電磁鐵或連線。
(三)電磁鐵沒有電流流過，壓力也上不去。
原因1，檢查電磁鐵線圈電阻為無限大，這是線圈斷了或電磁鐵引線脫焊了。解決方法是更換電磁鐵線圈或焊好電磁鐵引線。
原因2，電磁鐵接插件松動，接觸不良。解決方法是擰緊插接件。
原因3，打開接插件，接線脫開了。解決方法是更換連線，或把斷線接上。
原因4，放大器和電磁鐵間連線斷開，或放大器端子接線脫開了。解決方法是更換連線，或把斷線接上。
原因5，放大器及設(shè)定器出故障。
(四)使壓力階躍變化時，小振幅的壓力波動不斷，設(shè)定壓力不穩(wěn)定。
原因，電磁鐵的導(dǎo)向部分和鐵芯表面附著污垢，妨礙鐵芯的運動。另外，主閥芯滑動部分沽有污垢，妨礙主閥芯的運動，由于這些污垢的影響，滯回增 大了。在滯回的范圍內(nèi)，壓力不穩(wěn)定。壓力波動不斷。解決方法是拆開并清洗閥和電磁鐵。檢查液壓油的污染度，如超過規(guī)定就要換油。
(五)壓力響應(yīng)緩慢。
原因1，電磁鐵鐵芯上設(shè)置的阻尼用固定節(jié)流孔及主閥芯節(jié)流孔被污垢堵住，電磁鐵鐵芯及主閥芯的運動受到不必要的阻礙。解決方法是拆開并清洗閥和電磁鐵。檢查液壓油的污染度，如超過規(guī)定就要換油。
原因2，沒流閥正常，可是液壓缸、管路的容積大，有空氣混入。通常發(fā)生設(shè)備剛裝好后開始運轉(zhuǎn)時或長期停機(jī)后有空氣混人的場合。解決方法:階躍響應(yīng)時間是隨著負(fù)載容積變化的。負(fù)載容積大則響應(yīng)時間長，因此，在和樣本值做比較時，要注意負(fù)載容積�？諝馊菀准性谟吐份^高部位，液壓缸中的空氣不易排出，設(shè)置放氣閥。
