style="text-indent:25px">能源效率比較：我們研究的結(jié)果表明，在往復(fù)運(yùn)動(dòng)周期較短（小于1min）的水平往復(fù)運(yùn)動(dòng)中，電動(dòng)執(zhí)行器的運(yùn)行能耗通常低于氣缸的運(yùn)行能耗，即更節(jié)能。而在往復(fù)運(yùn)動(dòng)周期較長(zhǎng)（大于1min）時(shí)，氣缸竟然變得更節(jié)能。這首先是由于終端停止時(shí)電動(dòng)執(zhí)行器的控制器通常需要消耗約10W的電力，而氣缸*有電磁閥耗電和氣體泄露，一般低于1W，即終端停止時(shí)間越長(zhǎng)，對(duì)氣缸越有利；其次電機(jī)在連續(xù)旋轉(zhuǎn)條件下的額定效率可達(dá)90%以上，但在直線往復(fù)運(yùn)動(dòng)（絲杠轉(zhuǎn)換）中的臺(tái)形加減速旋轉(zhuǎn)條件下的平均效率卻不到50%。在豎直往復(fù)運(yùn)動(dòng)時(shí)，夾持工件的保持動(dòng)作要求不斷供給電流給電動(dòng)執(zhí)行器以克服重力，而氣缸只需關(guān)閉電磁閥即可，耗電極少。因此在豎直往復(fù)運(yùn)動(dòng)時(shí)電動(dòng)執(zhí)行器相比氣缸的能耗優(yōu)勢(shì)不是很大。中山帶導(dǎo)軌無(wú)桿氣缸為減輕重量并防銹，常使用鋁合金壓鑄，微型缸有使用黃銅材料的。</p><div

1.氣缸檢修重新裝配時(shí)，零件必須清洗干凈，特別要防止密封圈被剪切、損壞，注意動(dòng)密封圈的安裝方向。 2.使用中應(yīng)定期檢查氣缸各部位有無(wú)異?，F(xiàn)象，各連接部位有無(wú)松動(dòng)等，軸銷式安裝的氣缸的活動(dòng)部位應(yīng)定期加潤(rùn)滑油。 3.氣缸拆下長(zhǎng)時(shí)間不使用時(shí)，所有加工表面應(yīng)涂防銹油，進(jìn)排氣口應(yīng)加防塵堵塞。 4.氣缸檢修重新裝配時(shí)，零件必須清洗干凈，不得將臟物帶入氣缸內(nèi)。特別須防止密封圈被剪切、損壞和注意動(dòng)密封圈的安裝方向。 5.制定出氣缸的月、季、年的維護(hù)保養(yǎng)制度，可參考方向閥的維護(hù)管理制度中規(guī)定的內(nèi)容。保養(yǎng)維護(hù)一般用的是油脂，通稱黃油，還要看活塞的溫度，脂類在活塞內(nèi)部形成一層很薄的膜，可使活塞更好的密封。氣缸和缸體鑄成一個(gè)整體時(shí)稱整體式氣缸;氣缸和缸體分別鑄造時(shí)，單鑄的氣缸筒稱為氣缸套。清遠(yuǎn)標(biāo)準(zhǔn)型氣缸生產(chǎn)廠家</p><p
