关于气缸的顶出速度与顶出力的问题
有一气缸φ63×500，垂直布置。要求顶出速度S=2～4mm/s，顶出力F=650N。气缸到空压机的距离即φ8mm管路长15m。实际安装：按顶出力算出气压值，调节气泵的输出压力至设计值。调整调速阀2以调节气缸的伸出速度。阀1全开。
现在的问题是①速度调节不到要求的2～4mm/s。即使阀1拧到底关死。气缸杆还是以大于2～4mm/s的速度伸出，且中途稍用力就能把气缸杆压回去。
②出现爬行现象，即使气缸空载也一样，不能匀速顶出。
请教各位高手社友指教，万分感谢！
最终目的：调节气缸以恒定的顶出力匀速顶出气缸杆。

关于气缸顶出力附图 做设备这么多年了，没有遇见这么低速度还用气缸的。强烈建议用电驱动方式。 气体可被压缩，液体基本不可压缩，气缸在充气过程中气体会被逐渐压缩，有压力累积与释放的过程，所以，你用气动实现匀速从根源上就不可行吧。 桃花岛 发表于 2024-7-23 09:33
关于气缸顶出力附图
“①速度调节不到要求的2～4mm/s。即使阀1拧到底关死。气缸杆还是以大于2～4mm/s的速度伸出，且中途稍用力就能把气缸杆压回去。”
看图，顶出是说带着负载向下伸出吧。伸出的速度超过了要求，这说明负载有自重，调节阀一点用也没有吗？

我理解，lz不是要匀速，是要慢速。
向下顶出，有负载重力的加成，按说调节气缸的两个阀，应该可以起到作用

不知道是不是用单向排气的调节阀， 用气液阻尼缸，价格实惠。气缸里注液压油那种，但是还是气源驱动。 人外有人 发表于 2024-7-23 09:57
做设备这么多年了，没有遇见这么低速度还用气缸的。强烈建议用电驱动方式。
经济上合理的前提是技术上可行，便宜是好，前提得能用才行。这个速度，直接气缸驱动怎么可能稳定。速度40mm/s一下尽量，还要求稳定就要不要考虑气缸，40mm/s以下极大概率会爬行，用过气缸的人都知道，更何况这都2-4mm了。
可以靠虑用气液增压缸，来解决气缸气压可压缩性，造成不稳定的问题，
