1.确定气缸选用的类型
2.确定气缸的安装方式
1.由负载性质及气缸运动速度选定负载率β值 负载率 β=F/P×100% 式中F-气缸活塞杆上所受的实际负载(N) P-气缸理论出力(N)理论输出力P(N) 推力P1=π/4×D2×p 式中D-气缸内径(cm) p-气缸工作压力(MPa)拉力P2=π/4×(D2-d2)×p 式中d-气缸活塞直径(cm) 负载性质 阻性负载 β=80% 惯性负载 一般场合 β=50% V<0.2m/s β=65% 高速运动 β=30%
2.由实际负载F及负载率β值，即将求出所需的气缸理论输出力P(P1或P2） P=F/β
3.由气缸的工作压力P及所需的理论输出力P(P1或P2）即可计算气缸缸径D，再按缸径系列尺寸圆整。

1.气缸安装使用前,应先检查气缸在运输过程中是否损坏,连接部件是否松动,然后再安装使用
2.安装时，气缸的活塞杆不得承受偏心载荷可横向载荷，应使载荷方向与活塞杆轴线相一致。
3.无论采用何种安装型式，都必须保证缸体不产生变形，气缸的安装底座有足够的刚度，不允许负载和活塞杆的连接用电焊焊接。
4.气缸水平安置时，特别是长行程气缸，用水平仪在进行三点位置（活塞杆全部伸出、中间及全部退回）检验。
5.速度调整
6.气缸安装完毕后，在工作压力范围内，无负载情况下运行2-3次，检查气缸是否正常工作
7.若采用带可调缓冲气缸，在开始工作前，应将缓冲调节阀调至阻尼最小位置，气缸正常工作后，再逐渐调节缓冲针阀，增大缓冲阻尼，直到满意为止。
8.采用CA、CB、TA、TB、TC型安装型式的气缸时，应定期在安装结合部位加润滑油。
