Pneumatic Actuator Performance

1. The rated output force or torque of the pneumatic device should comply with the regulations of GB/T12222 and GB/T12223
2. Under no-load condition, input the air pressure specified in "Table 2" into the cylinder, and its movement should be smooth without jamming or crawling.
3. Under the air pressure of 0.6MPa, the output torque or thrust in the opening and closing directions of the pneumatic device should not be less than the value indicated on the nameplate of the pneumatic device, and the movement should be flexible, and permanent deformation and deformation of various parts are not allowed. Other abnormal phenomena.
4. When the maximum working pressure is used for the sealing test, the amount of air leaking from each back pressure side is not allowed to exceed (3+0.15D) cm3/min (standard state); the amount of air leaking from the end cover and output shaft The air volume is not allowed to exceed (3+0.15d)cm3/min.
5. The strength test is carried out with 1.5 times the maximum working pressure. After maintaining the test pressure for 3 minutes, no leakage or structural deformation is allowed in the cylinder end cover and static sealing parts.
6. The number of action lifespan. The pneumatic device simulates the action of a pneumatic valve. While maintaining the output torque or thrust capability in both directions, the number of opening and closing operations should be no less than 50,000 times (open-close cycle is one time).
7. For pneumatic devices with buffer mechanisms, no impact is allowed when the piston moves to the end position of the stroke.
