2、度高。二、主要技術(shù)指標(biāo)：1）防爆電機(jī)：電源電壓：380VAC（三相四線制）功率：0.75KW轉(zhuǎn)速：1450r/min2）控制電源：220VAC（二線制）2、齒輪泵：排量：5L/min額定壓力：6MPa3、蓄能器：額定壓力：10MPa容積：10L4、壓力變送器：1）系統(tǒng)壓力：量程：010MPa2）立管壓力：量程：040MPa3)套管壓力：量程：040MPa所有變送器輸出信號(hào)為：420mA5、電閥位變送器：量程：0180度輸出信號(hào)：420mA6、數(shù)字顯示控制儀表：顯示位數(shù)：4位精度：0.5%FS1字7、輸出扭矩：150Kgfm8、溢流閥調(diào)定為7.5MPa三、整機(jī)配備和工作原理：1、電動(dòng)液控節(jié)流管匯

3、控制箱是由控制箱、壓力變感器、電閥位變送器、電纜、液壓管線等組成?？刂葡溆煞辣瑑x表箱、防爆電機(jī)、齒輪泵、蓄能器、溢流閥、截止閥、三位四通換向閥、手動(dòng)試壓泵、油箱、液壓元件、電器控制元件、數(shù)字顯示控制儀表等組成。工作原理液壓工作原理見(jiàn)圖一電動(dòng)節(jié)流管匯控制箱它集電動(dòng)、液壓于一體，將外部電能轉(zhuǎn)換成液壓能量去控制液動(dòng)節(jié)流閥的開(kāi)啟和關(guān)閉。啟動(dòng)防爆電機(jī)帶動(dòng)齒輪泵，高壓液壓油經(jīng)單向閥，進(jìn)入蓄能器，蓄能器隨著液壓油進(jìn)入量增多而壓力增高，當(dāng)壓力升至設(shè)定值后電機(jī)停止，扳動(dòng)三位四通換向閥可達(dá)到控制節(jié)流閥開(kāi)、關(guān)的目的。速度調(diào)節(jié)閥作用是調(diào)節(jié)液壓油流量，控制液動(dòng)節(jié)流閥開(kāi)或關(guān)的速度。溢流閥是當(dāng)控制電路出現(xiàn)故障，即系統(tǒng)油壓升
