淺析伺服油缸的特點(diǎn)：靜壓支撐是一種無(wú)接觸的密封，由于壓差關(guān)系，使油液通過(guò)較小的節(jié)流孔形成一層很薄的油膜，從而替代普通密封件達(dá)到密封的效果，其所承受的比較大側(cè)向力。由于有接觸的密封和防塵圈不承受壓力，活塞桿的導(dǎo)向采用對(duì)摩擦力優(yōu)化的導(dǎo)向元件，因此在整個(gè)壓力范圍內(nèi)的啟動(dòng)摩擦力非常小，由此保證了伺服油缸的高動(dòng)態(tài)性和高壽命等特性。

style="text-indent:25px">淺談伺服油缸的快速和穩(wěn)定性：伺服油缸為提高生產(chǎn)率，要求各類(lèi)機(jī)床和機(jī)械設(shè)備有較高的退刀速度，為滿足這一要求，數(shù)控液壓伺服油缸必須具有較高的運(yùn)行速度。根據(jù)公式n=60f／(zm)，其中，廠為輸入脈沖頻率，可見(jiàn)其快速性與數(shù)控系統(tǒng)能提供的步進(jìn)電動(dòng)機(jī)運(yùn)行頻率有關(guān)，與液壓泵站能提供的油液流量也有關(guān)，在設(shè)計(jì)時(shí)應(yīng)根據(jù)實(shí)際需要計(jì)算確定。就油缸本身而言，根據(jù)公式u1—8Q-（πd2）（Vl為活塞速度；Q為液壓泵的流量；D為缸簡(jiǎn)直徑）可知快速性取決于油缸的流量，就系統(tǒng)而言還取決于伺服閥的開(kāi)啟度。即υ=υ1Ae／r式中，υ為活塞運(yùn)行速度；υ1為閥開(kāi)口處流速；A為閥開(kāi)口長(zhǎng)度；e為閥開(kāi)口寬度；r為活塞半徑。</p><p style="text-indent:25px">怎么從外形區(qū)分伺服油缸和普通油缸：傳感器是實(shí)時(shí)檢測(cè)汽缸或者油缸動(dòng)作位移量的，通過(guò)電液轉(zhuǎn)換把檢測(cè)到信號(hào)實(shí)時(shí)反饋到PLC控制系統(tǒng)中，經(jīng)處理后負(fù)反饋出誤差信號(hào)，自動(dòng)調(diào)用指令驅(qū)動(dòng)液力（氣動(dòng)）動(dòng)力執(zhí)行機(jī)構(gòu)達(dá)到預(yù)定動(dòng)作狀態(tài)，此過(guò)程是按照程序自動(dòng)完成的，且是閉環(huán)控制的回路。其中動(dòng)力執(zhí)行油缸就是伺服油缸。而普通油缸像工程機(jī)械上油缸多數(shù)是在滿量程和零位裝有接近開(kāi)關(guān)，限制過(guò)載，不需要全過(guò)程檢測(cè)油缸動(dòng)作位移，很明顯也不需要伺服控制，除非是個(gè)智能工程機(jī)械才用伺服油缸。伺服油缸為提高生產(chǎn)率，要求各類(lèi)機(jī)床和機(jī)械設(shè)備有較高的退刀速度，為滿足這一要求。</p><div

style="text-indent:25px">伺服油缸缸摩擦相對(duì)普通油缸要小一點(diǎn)，如果是高頻作動(dòng)差距會(huì)明顯出現(xiàn)，伺服缸是為控制設(shè)計(jì)的，更看重動(dòng)態(tài)性能。在液壓中控制元件是閥，動(dòng)力元件是泵，缸和馬達(dá)屬于執(zhí)行元件。伺服液壓的重要是控制不是液壓，只是因?yàn)橐簤菏莻鲃?dòng)功率體積比比較大的方式，更符合大力帶小負(fù)載（相對(duì)），提高響應(yīng)的原則才選擇了液壓傳動(dòng)，其實(shí)伺服液壓跟伺服電機(jī)什么的都類(lèi)似，重點(diǎn)是在控制上。當(dāng)今液壓系統(tǒng)的重要問(wèn)題是提高傳動(dòng)效率，節(jié)能，所以才有什么負(fù)載敏感，閉式系統(tǒng)的出現(xiàn)，而伺服系統(tǒng)是典型的低效率系統(tǒng)，以效率換動(dòng)態(tài)響應(yīng)，正好相反，當(dāng)然伺服系統(tǒng)也希望效率越高越好。液壓和伺服液壓明顯是兩大塊，就是因?yàn)槎叩膫?cè)重點(diǎn)完全不同。伺服缸要考慮磨擦力，在伺服系統(tǒng)中它影響了系統(tǒng)的動(dòng)態(tài)響應(yīng)，控制精度，穩(wěn)定性等。在伺服油缸設(shè)計(jì)中要選取用低磨擦系數(shù)的密封件，而運(yùn)動(dòng)面要比普通的更加精密。伺服油缸配套伺服閥或電液閥配套位移，傳感器反饋信號(hào)到plc進(jìn)行信號(hào)采集發(fā)出指令。微機(jī)伺服萬(wàn)能試驗(yàn)機(jī)定制</p><p
