當(dāng)向動圈輸入正向節(jié)制電流時，電磁力使動圈與節(jié)制閥芯向下移動，此時上節(jié)流口關(guān)小，下節(jié)流口開大，隨動活塞上腔的壓力升高，從而推動活塞下移當(dāng)活塞位移到達(dá)節(jié)制閥芯的位移量時，上、下節(jié)流口過流面積重又恢復(fù)相等，隨動活塞兩頭的液壓推力恢復(fù)相等，隨動活塞便不用人的勞力穩(wěn)定在這一新的平衡位置
2.因為力電動機(jī)推力的增加以及彈簧剛度的增加使其頻率相應(yīng)由CSV9的≥6Hz(-3db)增至≥14Hz
2.壓力零漂：工作壓力自60%至100%PS變化時輸出行程變化與總行程之比
(-3db)
CSV9H型電液轉(zhuǎn)換器是在CSV9的根蒂根基上革新而成，革新后CSV9H型電液轉(zhuǎn)換器就象下三個特點(diǎn)：1.接納大電流推動，其動圈式力電動機(jī)的推力比原CSV9要高出3倍，所以其閥芯的防卡能力即抗油液的
直接替代CSV9從而使電站調(diào)速機(jī)組的可靠性、動特性與精密度有很大提高
3.因為零件加工精密度的提高，使死區(qū)由CSV9的≤2.5%提高至≤1%，使壓力零漂由CSV9的≤2%提高至
二、主要技能指標(biāo)
其毗連板安裝面外貌粗糙度應(yīng)小于Ra6.3
注：1.死區(qū)：對于應(yīng)于同一輸出值的兩個不同輸入值之差與總行程之比
CSV9，CSV9H電液轉(zhuǎn)換器的電流-位移轉(zhuǎn)換部門是由永久磁鐵、導(dǎo)磁罩、內(nèi)外導(dǎo)磁板、動圈及彈簧所構(gòu)成的動圈式力電動機(jī)，液壓伺服放大部門是由節(jié)制閥芯、隨動活塞所構(gòu)成的具備直接位置反饋的三通道滑閥節(jié)制差動缸(詳見圖一)安裝體式格局為板式毗連
