低價(jià)*原裝德國(guó)力士樂(lè)比例伺服閥

     REXROTH力士樂(lè)比例閥其實(shí)缺點(diǎn)極多：能耗浪費(fèi)大、容易出故障、抗污染能力差、價(jià)格昂貴等等等等，好處只有一個(gè)：動(dòng)態(tài)性能是所有液壓閥中zui高的。就憑著這一個(gè)優(yōu)點(diǎn)，在很多對(duì)動(dòng)態(tài)特性要求高的場(chǎng)合不得不使用伺服閥，如飛機(jī)火箭的舵機(jī)控制、汽輪機(jī)調(diào)速等等。動(dòng)態(tài)要求低一點(diǎn)的，基本上都是比例閥的天下了。

    一般說(shuō)來(lái)，好像伺服系統(tǒng)都是閉環(huán)控制，比例多用于開(kāi)環(huán)控制；其次比例閥類(lèi)型要多，有比例壓力、流量控制閥等，控制比伺服藥?kù)`活一些。從他們內(nèi)部結(jié)構(gòu)看，伺服閥多是零遮蓋，比例閥則有一定的死區(qū)，控制精度要低，向應(yīng)要慢。但從發(fā)展趨勢(shì)看，特別在比例方向流量控制閥和伺服閥方面，兩者性能差別逐漸在縮小，另外比例閥的成本比伺服閥要低許多，抗污染能力也強(qiáng)！
