气缸安装使用注意事项：
安装前应先空载条件下试运行，正常后方能安装。
按使用条件选用安装形式，安装时须注意：
a、耳环安装、中间轴销安装，其作用力应处同一平面内。
b、法兰安装，其作用力与支承中心处在同一轴线上，法兰与支承座的链接应使用法兰面承受作用力，而不使其固定螺钉承受拉力。
c、气缸活塞杆不允许承受偏载荷或横向荷载，长行程气缸，应加支承或导向装置，接入管前要清除管内赃物，杂物进入气缸。
经常检查紧固件，及时松动脱落。要时可以调节节流阀，一调整缓冲效果，避免活塞与气缸盖碰撞，损坏机件。
pre-running the cylinder under idle load condition before installation,install it after everything is OK.
sele the installation method according to usage condition,pay attention to the following points:
a.The force will be applied pn pne surface when mounting the tongue and middle axle pin.
B.The applied force will be on one axis with the supporting center when mounting flange make the flage bear
the effe instead of its fixing bolt when the flange is conneed with the supporting base.
c.The cylinder piston rob is t allowed to bear inclined load or lateral load,cylinder with overlength travel
will add support or guiding device,empty the pipe before conneion to avoid dirt enter into the pipe.
Check the fastener regularly to avoid loosening happens.
lf it isnecessary,adjust the throttle valve to regular the buffer erre and aviod the piston to strike with the cylinder
tap to damage the parts.
