ZH series pneumatic actuator Introduction of ZH series pneumatic actuator to single acting pneumatic actuator
Performance of single acting pneumatic actuator:
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 condition, input the air pressure specified in Table 2 into the cylinder, and the action is stable without jamming and creeping.
3. Under the pressure of 0.6MPa, the output torque or thrust of the pneumatic device in the switch direction shall not be less than the value marked on the label of the pneumatic device. The action shall be flexible, and all parts shall be free of deformation and other abnormal phenomena.
4. When conducting the sealing test under large working pressure, the amount of air leaking shall not exceed (3)+0.15d) cm3/min (standard state); The air leakage of end cover and output shaft shall not exceed (3)+0.15d) cm3/min.
5. The high working pressure strength test shall be conducted under 1.5 times. Maintain the test pressure for 3min, and the cylinder end cover and static seal shall be free of leakage and structural deformation.
6. Action life. A pneumatic device that simulates the action of a pneumatic valve. The number of opening and closing operations shall not be less than 50000 times (one opening and closing cycle), while maintaining the output torque or thrust capacity in both directions.
7. For the pneumatic device with buffer mechanism, when the piston moves to the end of the stroke, impact is not allowed.
