德國Rexroth力士樂比例閥規(guī)格特點
Rexroth力士樂氣動和力士樂液壓是我們常做的兩大產(chǎn)品,包括電磁閥、比例閥、換向閥、柱塞泵、油泵、葉片泵等。我司從2006年注冊以來,已經(jīng)有了將近9年的銷售經(jīng)驗,我們從租房面積20平米到126平米,公司規(guī)模在不斷的擴大,隨著時間的見證,我們所以全體員工服務(wù)質(zhì)量越來越負責(zé),歡迎新老客戶前來查看。
德國Rexroth力士樂比例閥規(guī)格特點
德國力士樂REXROTH比例閥也就是說,伺服閥的主閥是靠前置級閥的輸出壓力來控制的,而前置級閥的壓力則來自于伺服閥的入口p,假如p口的壓力不足,前置級閥就不能輸出足夠的壓力來推動主閥芯動作。
德國力士樂REXROTH比例閥其實缺點極多:能耗浪費大、容易出故障、抗污染能力差、價格昂貴等等等等,好處只有一個:動態(tài)性能是所有液壓閥中zui高的。就憑著這一個優(yōu)點,在很多對動態(tài)特性要求高的場合不得不使用伺服閥,如飛機火箭的舵機控制、汽輪機調(diào)速等等。動態(tài)要求低一點的,基本上都是比例閥的天下了。一般說來,好像伺服系統(tǒng)都是閉環(huán)控制,比例多用于開環(huán)控制;其次比例閥類型要多,有比例壓力、流量控制閥等,控制比伺服藥靈活一些。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!
