MOOG G631-3006B伺服驅(qū)動器
1.產(chǎn) 品 資 料 介 紹：
- 兩級機(jī)械反饋架構(gòu)：MOOG G631-3006B 采用 “力矩馬達(dá) + 雙噴嘴擋板先導(dǎo)級 + 主滑閥” 的兩級設(shè)計，通過懸臂彈簧桿實現(xiàn)閥芯位置機(jī)械反饋，與 D633-317B 的直動式 DDV 架構(gòu)形成顯著差異。這種設(shè)計雖增加傳動環(huán)節(jié)，但在大流量場景下控制穩(wěn)定性更優(yōu)，適配航空航天測試臺等高精度需求場景。
- 干式力矩馬達(dá)驅(qū)動：搭載干式雙氣隙永磁力矩馬達(dá)，無需油液浸泡冷卻，相比 D633-317B 的線性力馬達(dá)，減少油液污染導(dǎo)致的磁滯誤差，同時避免馬達(dá)內(nèi)部磨損，適配長期連續(xù)運行的工業(yè)自動化設(shè)備。
- 標(biāo)準(zhǔn)化兼容安裝設(shè)計：采用 ISO 4401 標(biāo)準(zhǔn)安裝底面，支持第五油口單獨控制，油口連接適配 SAE 標(biāo)準(zhǔn)螺紋，雖接口類型少于 D633-317B 的法蘭 / 螺紋可選配置，但可直接替換同規(guī)格傳統(tǒng)伺服閥，降低液壓系統(tǒng)改造難度。
- 寬域流量壓力適配：最大工作壓力達(dá) 35MPa，35bar 壓降下額定流量覆蓋 3.8-100L/min，流量調(diào)節(jié)范圍與 D633-317B（30-80L/min）形成互補(bǔ)，既能滿足小型精密設(shè)備的低流量需求，也可適配中型執(zhí)行機(jī)構(gòu)的動力供給。
- 高頻響動態(tài)特性：頻率響應(yīng)達(dá) 40-60Hz，閥芯最大位移 1.27mm，通過機(jī)械反饋桿快速建立力矩平衡，100% 階躍響應(yīng)時間雖略長于 D633-317B 的 15ms，但在低壓差工況下響應(yīng)一致性更優(yōu)，保障吹塑設(shè)備的流量穩(wěn)定性。
- 高精度控制指標(biāo)：雙噴嘴擋板結(jié)構(gòu)實現(xiàn)低摩擦傳動，滯環(huán)誤差≤±1%，分辨率較 D633-317B 的 0.1% 略低，但機(jī)械反饋的抗干擾能力更強(qiáng)，在電磁環(huán)境復(fù)雜的冶金設(shè)備中控制精度更穩(wěn)定。
MOOG G631-3006B伺服驅(qū)動器 英文資料：
1、 Infrastructure and driving characteristics
Two level mechanical feedback architecture: MOOG G631-3006B adopts a two-stage design of "torque motor+dual nozzle baffle pilot stage+main slide valve", and achieves mechanical feedback of valve core position through cantilever spring rod, which is significantly different from the direct acting DDV architecture of D633-317B. Although this design increases the transmission link, it has better control stability in high flow scenarios and is suitable for high-precision demand scenarios such as aerospace test benches.
Dry torque motor drive: Equipped with a dry dual air gap permanent magnet torque motor, it does not require oil immersion cooling. Compared with the D633-317B linear force motor, it reduces hysteresis errors caused by oil pollution and avoids internal wear of the motor, making it suitable for long-term continuous operation of industrial automation equipment.
Standardized compatible installation design: Adopting ISO 4401 standard installation bottom surface, supporting separate control of the fifth oil port, and adapting SAE standard thread for oil port connection. Although the interface type is less than D633-317B flange/thread optional configuration, it can directly ｒｅｐｌａｃｅ traditional servo valves of the same specification, reducing the difficulty of hydraulic system transformation.
2、 Core performance and control accuracy
Wide range flow pressure adaptation: The maximum working pressure reaches 35MPa, and the rated flow covers 3.8-100L/min under a pressure ｄｒｏｐ of 35bar. The flow regulation range complements D633-317B (30-80L/min), which can meet the low flow requirements of small precision equipment and also adapt to the power supply of medium-sized actuators.
High frequency response dynamic characteristics: The frequency response reaches 40-60Hz, the maximum displacement of the valve core is 1.27mm, and torque balance is quickly established through a mechanical feedback rod. Although the 100% step response time is slightly longer than the 15ms of D633-317B, the response consistency is better under low pressure ｄｒｏｐ conditions, ensuring the flow stability of the blow molding equipment.
High precision control indicators: The dual nozzle baffle structure achieves low friction transmission, hysteresis error is ≤± 1%, and the resolution is slightly lower than the 0.1% of D633-317B. However, the anti-interference ability of mechanical feedback is stronger, and the control accuracy is more stable in metallurgical equipment with complex electromagnetic environment.
