The TC series consists of cylinder, actuator control accessories and manual device, manual device integrated in the box shell, the steel shell to support and protection, to ensure continuous operation of equipment in harsh environments.

The regulating type actuator transfers the electric signals to the positioner, and controls the pressure of the two ends of the cylinder by the positioner, so as to realize the function of adjusting the opening of the torque device through the electric signal.

The switch type actuating mechanism controls the electromagnetic valve to gain electricity and loses the electricity, controls the cylinder both ends to enter the gas the direction transformation, realizes through the gain electricity and loses the electricity to control the torque equipment the switch function.

With the increasing capacity of modern power plant units, terminal components are required
The control moment (damper, fan, etc.) is also increasing, which is often required
The actuator can achieve more than 20000Nm by torque Look faster.
TC series pneumatic actuator fully meets these requirements:
Pneumatic actuators with various sizes (maximum cylinder diameter 520mm) are suitable
Different torque should be given; proper accessory design as well as pneumatic circuit can be formed Enough to guarantee fast response time.

TC series of actuators with the gas lock system, to ensure high
Degree of security in case of emergency. When the gas source is faulty, the gas is out of order
The lock activation is automatically engaged with manual operation, and it realizes the position before the fault
Mechanical locking.

Platform installation and anchor bolt fixing The shaft end is provided with an output rocker arm, and both ends of the shaft are splined structures The initial position and direction of the whole rocker arm Two output angles, 90 degrees and 70 degrees
Solid box structure (all made of steel plate) The box has two functions: protection and support The space in the box can ensure the correct installation of the actuator and various accessories
The actuator is SC series cylinder actuator, with CDG patented permanent lubrication system, within the service life (30 years), do not need refueling removable panels, convenient maintenance and maintenance

 Enclosure：

application:

Widely used in electric power, steel, petrochemical and other industries, the actuator can control all kinds of valves, converter torque torque transmission and play equipment, this mechanism can be a certain distance through the connecting rod, making it more convenient in use and installation.

Working principle:

Pneumatic pressure switch connected with air lock valve (D) when the gas source is lost
Lost air source, spring reset operation, two sets of three-way valve to air pipe locking
The position of the actuator keeps the gas source out of position. At the same time, air lock
The device can send out the "state signal" which is out of breath as a general monitoring or participation
Logical control of system.

When the three way reversing valve (MC) is automatically controlled, the manual position is controlled at the connection position
When the clutch is in the closed position; gas separation, gas engagement. When system
When the gas source is lost, the clutch is meshed automatically with the handwheel mechanism. Therefore, the whole
All of the systems are locked mechanically before the gas is lost.

If manual control is carried out by hand wheel, the bypass valve (BP) should be opened
The cylinder is connected to the lower chamber and the cylinder is in free motion.
In addition, it is recommended to switch the three way reversing valve after the pneumatic lock (D) action
(MC) to the closed position, to ensure the stable engagement of the clutch, to prevent the gas source
Recovery misoperation.

Switching from manual control to automatic control

When manually switching to automatic control, remember not to build
Position deviation for switching. It is only recommended by the terminal adjustment mechanism
When the torque is transferred to the pneumatic actuator ahead of time, the clutch is disengaged
Unperturbed switching.

CDG designs this system and has a patent on it, and this system can be used in the system
Operation under the condition of maximum reliability.

When the gas pressure is restored, the air lock device is automatically reactivated, so the air lock device is automatically reactivated,
By closing the bypass (BP), the actuator can operate freely. Slow through
The control signal corresponding to the preset position of the terminal regulating mechanism is slowly reduced
In order to ensure that the actuator can fully bear by the terminal adjustment mechanism generated
Condition of moment. Under this balance condition, there is no load on the handwheel mechanism,
Switch the three way reversing valve (MC) to the connecting position, and the clutch is the same as the handwheel mechanism
Disengage and revert to automatic control state. 

Ensure the required torque limit pressure 10-20%.
