VT-VRRA1-537-20/V0石油行業(yè)的力士樂REXROTH放大器

博士力士樂電液比例閥對簡化工程機(jī)械操作、提高效率和作業(yè)精度以及實現(xiàn)智能化作業(yè)都有著極其重要意義，其性能進(jìn)步提高和應(yīng)用范疇日益拓寬必將使工程機(jī)械技巧到較大程度提高。

博士力士樂電液比例閥包含比例流量閥、比例壓力閥、比例換向閥。工程機(jī)械液壓操作特點，以結(jié)構(gòu)形式劃分電液比例閥主要有兩類：類是螺旋插裝式比例閥（screwincartridgeproportionalvalve），另類是滑閥式比例閥（spoolproportionalvalve）。

博士力士樂螺旋插裝式比例閥是螺紋將電磁比例插裝件固定油路集成塊上元件，螺旋插裝閥應(yīng)用機(jī)動、節(jié)省管路和成本廉等特點，近年來工程機(jī)械上應(yīng)用越來越普遍。常用螺旋插裝式比例閥有二通、三通、四通和多通等形式，二通式比例閥主比例節(jié)流閥，它常它元件起構(gòu)成復(fù)合閥，對流量、壓力進(jìn)行把持；三通式比例閥主比例減壓閥，也是移動式機(jī)械液壓系統(tǒng)中應(yīng)用較多比例閥，它主對液動操作多路閥先導(dǎo)油路進(jìn)行操作。利用三通式比例減壓閥可以代替?zhèn)鹘y(tǒng)手動減壓式先導(dǎo)閥，它比手動先導(dǎo)閥多機(jī)動性和高把持精度。可以制成如圖1所示比例伺服把持手動多路閥，不同輸入信號，減壓閥使輸出活塞不同壓力或流量進(jìn)而實現(xiàn)對多路閥閥芯位移進(jìn)行比例把持。四通或多通螺旋插裝式比例閥可以對工作裝置實現(xiàn)單把持。

博士力士樂滑閥式比例閥又稱分配閥，是移動式機(jī)械液壓系統(tǒng)zui基礎(chǔ)元件之，是能實現(xiàn)方向與流量調(diào)節(jié)復(fù)合閥。電液滑閥式比例多路閥是比較理想電液轉(zhuǎn)換把持元件，它保存了手動多路閥基礎(chǔ)功效，還增加了地位電反饋比例伺服操作和負(fù)載傳感等把持手段。它是工程機(jī)械分配閥新?lián)Q代。

出于成本考慮和工程機(jī)械把持精度要求不高特點，般比例多路閥內(nèi)不配置位移感應(yīng)傳感器，電子檢測和糾錯功效。，閥芯位移量容易受負(fù)載變化引起壓力波動影響，操作進(jìn)程中要靠視覺察看來保證作業(yè)完成。電控、遙控操作時應(yīng)注意外界干預(yù)影響。近來，電子技巧發(fā)展，人們越來越多采用內(nèi)裝差動變壓器（ＬＤＶＴ）等位移傳感器構(gòu)成閥芯地位移動檢測，實現(xiàn)閥芯位移閉環(huán)把持。這種由電磁比例閥、地位反饋傳感器、驅(qū)動放大器和其它電子電路組成高度集成比例閥，定校正功效，可以有效克服般比例閥缺點，使把持精度到較大提高。
