SMC速度控制阀SSC(ASS)结构原理

SMC具有固定节流孔和急速供气机能的速度控制阀SSC(ASS)作用

在中泄式电磁阀驱动气缸的回路中,当中泄阀处于中位时,气缸活塞两侧都排空。当换向阀切换至左位时,因无杆腔很快充气,有杆腔初始时为大气压力,故活塞杆会急速伸出伤人或损坏设备。若将无杆侧的排气节流式速度控制阀改装成固定节流孔和有急速供气机能的速度控制阀(SSC系列),则可避免上述活塞杆急速伸出事故。

SMC 具有固定节流孔和急速供气机能的速度控制阀SSC(ASS)的使用注意

1)SSC阀应安装在防止活塞杆急速伸出的供气侧,希望直接诶装在气缸上。若与气缸用配管连接,一旦配管长,不仅速度控制变差,在正常动作时,其始动作时间也变长,甚至速度控制不起作用。
2)100mm以下短行程气缸及摆动气缸不要使用SSC阀。
3)负载率在50%以下使用SSC阀,以免正常动作时的速度控制不起作用。
4)排气节流控制的SSC阀,防止活塞杆急速伸出的初始速度是不可调节的,若希望低于初期速度且可调,则应选用进气节流控制的SSC阀(ASS110·310)。
5)缸内有残压的回路,使用进气节流式的速度控制阀就能防止活塞杆急速伸出。
