1. The transmission case adopts the parallel double guidance stability enhancement design, and integrates the design concept of transmission stability enhancement for the first time. It is an upgraded product of ordinary fork actuator. The structure strength, transmission efficiency and transmission stability are improved.
2. Pneumatic priority and ESD function emergency priority in any case: during pneumatic operation, no matter what position the manual pump selection switch is, the control system can carry out pneumatic control and operate the valve according to the given control signal.
3. The patented multi-functional manual pump can realize all-round operation, and the hydraulic control conversion isolation circuit can test the functions of the control system with pressure and carry out on-line maintenance of the valve and actuator without operating the valve.
4. Hall type induction button is adopted, embedded design is anti-collision and anti misoperation.
Improve control performance of control unit plpg2010 and explosion-proof grade Exd ict6
Protection grade IP68
5. Break through the traditional design: completely realize the phenomenon of high gas-liquid separation and oil injection during the operation of pneumatic hydraulic actuator.
6. Integrated insulation filter is adopted to solve the problem of gas filtration and electrical insulation, and online cleaning can be realized to meet the accuracy of pressure transmitter detection and the cleanness of actuator air source
7. When the valve is driven under the same conditions, the size and weight of CDG actuator are reduced and the overall dimension is smaller. It can reduce the space occupation of actuator mechanism and reduce the load of pipeline and valve.
8. The actuator control system is designed according to the low pressure of 0.4MPa, which solves the problem that a considerable part of pipeline pneumatic hydraulic actuators can not work normally. High pressure can work up to 16 MPa
9. Improve the action response time and speed of the actuator, reduce the emergency shutdown accident state, and solve the problem that the valve can not realize fast shut-off
10. Optimize the actuator space layout, solve the problem that the operator needs to operate the actuator on both sides of the pipeline, and improve the escape space of the operator in case of emergency
11. Adopt fully welded oil cylinder to reduce the weight of oil cylinder and eliminate leakage of oil cylinder |
