2、故障原因a、曲軸軸承連桿滾針軸承或軸承及活塞銷孔嚴(yán)重磨損、松動(dòng)，蘇州薄型氣缸哪家質(zhì)量好，在活塞上下行程轉(zhuǎn)速的瞬間，活塞頂會(huì)碰撞氣門蓋。 b、也可能由于制造質(zhì)量的原因或使用的配件不配套，使活塞達(dá)到上止點(diǎn)時(shí)超高而碰撞氣門蓋。 3、排除方法拆下氣缸蓋，檢查碰撞的情況，可根據(jù)情況更換合格的產(chǎn)品和配套的零件，蘇州薄型氣缸哪家質(zhì)量好，也可以加上一個(gè)合適的氣缸襯墊，使汽缸蓋升高而不致被碰撞，如果因相關(guān)件磨損嚴(yán)重，應(yīng)修理或更換其磨損嚴(yán)重的零部件。優(yōu)點(diǎn)：重心較低，配重均衡，給車輛帶來(lái)更好操控性。蘇州薄型氣缸哪家質(zhì)量好</p><div

㎜的余量。2.活塞的運(yùn)動(dòng)速度主要取決于氣缸輸入壓縮空氣流量、氣缸進(jìn)排氣口大小及導(dǎo)管內(nèi)徑的大小。要求高速運(yùn)動(dòng)應(yīng)取大值。氣缸運(yùn)動(dòng)速度一般為 50～800 ㎜/s。對(duì)高速運(yùn)動(dòng)氣缸，應(yīng)選擇大內(nèi)徑的進(jìn)氣管道；對(duì)于負(fù)載有變化的情況，為了得到緩慢而平穩(wěn)的運(yùn)動(dòng)速度，可選用帶節(jié)流裝置或氣
