Performance introduction of single acting pneumatic actuator
Single acting pneumatic actuator performance:
1. The rated output force or torque of the pneumatic device shall meet the requirements of GB/T12222 and GB/T12223
2. Under no-load conditions, input the air pressure specified in Table 2 into the cylinder, and the action should be smooth, without sticking and crawling.
3. Under the pressure of 0.6mpa, the output torque or thrust of the pneumatic device in the switching direction shall not be less than the value marked on the label of the pneumatic device. The action shall be flexible, and the parts shall not have deformation and other abnormal phenomena.
4. When the sealing test is carried out under high working pressure, the air leakage shall not exceed (3)+ 0.15D) cm3/min(standard state); Leakage of end cover and output shaft shall not exceed (3)+0.15d) cm3/min.
5 large working pressure strength test 1.5 times. Keep the test pressure for 3min and the cylinder end cover and static seal are not allowed to leak and structural deformation.
6. Action life. Pneumatic device that simulates the action of pneumatic valve. The number of open and close operations shall be no less than 50000 (one open and close cycle) while maintaining output torque or thrust capability in both directions.
7. For pneumatic devices with buffer mechanism, when the piston moves to the end of the stroke, it is not allowed to impact.
