力士樂(lè)高頻響比例閥2WFCE50S1000L-10/M/24G1原裝 新品
德國(guó)Rexroth高頻響比例閥是比例閥中動(dòng)態(tài)響應(yīng)性能zui接近伺服閥,雖然頻率和敏感度比不上伺服閥,但是它無(wú)零位死區(qū),高精度、高頻響,對(duì)油液的清潔度要求比伺服閥低,具有更高的工作可靠性。
采用力士樂(lè)高頻響比例閥時(shí),應(yīng)同時(shí)采用蓄能器或增設(shè)緩沖回路,消除液壓沖擊,因?yàn)楣苈返臎_擊也影響著高頻響比例閥的穩(wěn)定響應(yīng)。油路長(zhǎng)度是否合理,管路壁厚是否合理,管路是否緊固,直接影響到管路的固有頻率,從而影響著比例閥的穩(wěn)定響應(yīng)。
