MOOG電液伺服閥D634-319C使用說明
電液伺服閥由力矩馬達(dá)和液壓放大器組成。 力矩馬達(dá)工作原理 磁鐵把導(dǎo)磁體磁化成N、S極，形成磁場。銜鐵和擋板固連由彈簧支撐位于導(dǎo)磁體的中間。擋板下端球頭嵌放在滑閥中間凹槽內(nèi)；線圈無電流時，力矩馬達(dá)無力矩輸出，擋板處于兩噴嘴中間；當(dāng)輸入電流通過線圈使銜鐵3左端被磁化為N極，右端為S極，銜鐵逆時針偏轉(zhuǎn)。彈簧管彎曲產(chǎn)生反力矩，使銜鐵轉(zhuǎn)過θ角。電流越大θ角就越大，力矩馬達(dá)把輸入電信號轉(zhuǎn)換為力矩信號輸出。 前置放大級工作原理 壓力油經(jīng)濾油器和節(jié)流孔流到滑閥左、右兩端油腔和兩噴嘴腔，由噴嘴噴出，經(jīng)閥9中部流回油箱力矩馬達(dá)無輸出信號時，擋板不動，滑閥兩端壓力相等。當(dāng)力矩馬達(dá)有信號輸出時，擋板偏轉(zhuǎn)，兩噴嘴與擋板之間的間隙不等，致使滑閥兩端壓力不等，推動閥芯移動。 功率放大級工作原理 MOOG電液伺服閥D634-319C使用說明
當(dāng)前置放大級有壓差信號使滑閥閥芯移動時，主油路被接通。滑閥位移后的開度正比于力矩馬達(dá)的輸入電流，即閥的輸出流量和輸入電流成正比；當(dāng)輸入電流反向時，輸出流量也反向。滑閥移動的同時，擋板下端的小球亦隨同移動，使擋板彈簧片產(chǎn)生彈性反力，阻止滑閥繼續(xù)移動；擋板變形又使它在兩噴嘴間的位移量減小，實(shí)現(xiàn)了反饋。當(dāng)滑閥上的液壓作用力和擋板彈性反力平衡時，滑閥便保持在這一開度上不再移 MOOG電液伺服閥D634-319C使用說明MOOG D661-4652/ 1156-421 G15JOAA6VSX2HA
