淺談液壓系統同步回路與同步精度
在各類液壓機器、設備、裝置中，實現同步運行功能是由液壓元件、管路按一定規律組合，并以液流介質傳遞，控制驅動兩個或兩個以上的執行器（液壓缸或液壓馬達）產生相同的線位移或角位移的運動，即謂之液壓同步回路。液壓同步回路是 液壓系統中回路之一，一般是由控制同步運動的液壓件，經管道至執行器，執行器的回油口經管路至油箱部分，即同步回路組成部分。
同步精度，表示同時數個同步執行器（液壓缸或液壓馬達）輸出力或轉矩的機件（液壓缸的活塞桿、液壓馬達輸出軸），它們之間運動速度或位移的誤差程度。常用同步誤差率來表示同步精度，其表達式為：
δ理=【（Q理－Q實）/ Q理】×100%
式中δ理──理論同步誤差率；
Q理──計算的理論流量；
Q實──輸入執行器的實際流量。
δ=【（Qmax―Qmin）/Qmin】×100%
式中δ──同步誤差率；
Qmax——輸入執行器的最大流量；
Qmin——輸入執行器的最小流量。
上式中δ可能有三個值，如上式即為一個值；若將上式中分母Qmin改為Qmax，則δ值相應就縮小；另外將上式中Qmin改為Q理，則δ又是一個值。但是實際工作中，一般是以實際同步誤差值作為要求（或列入技術條件或列入合同），一種以絕對值如同步精度0. 5mm，另一種是同步精度相對值如同步精度0. 5mm/m，即每行程1m同步誤差允許0．5mm/m，當然具體的同步誤差值是由具體條件決定的。
在具有液壓系統同步回路的機械設備中，若同步回路的同步精度達不到要求，則該機械設備就不能充分發揮效用，甚至成廢品一堆，不但浪費人力物力，而且使生產規劃落空。
由此看來，液壓同步回路在要求具有同步運動功能的機器、設備、裝置中占很重要的地位。因此大蘭液壓廠家提醒大家在設計液壓同步回路時，首先要保證回路能達到同步精度要求，其次要適合其他技術要求，同時也符合使用環境等。故要設計出優良的液壓同步回路，除熟知這些要求外，必須對組成這些回路的液壓元件的結構、原理、功能、適應條件有清楚的了解，對涉及的儀器、電氣電子器件等也應該有一定的了解。
液壓同步回路雖然屬于液壓傳動系統（以傳遞動力為主、傳遞信息次之），但是隨著科學技術飛躍發展，尤其電子技術進步以及對同步精度要求越來越高，
如今液壓控制系統（以傳遞信息為主，傳遞動力次之）已與液壓系統傳動系統日益融合，有時在液壓系統中很難分清哪些屬于傳動系統，哪些屬于控制系統。故液壓工作者尤其設計者對控制理論及電子電氣技術知識也應有一定程度的了解，否則很難得心應手從事液壓技術工作。
