High Pressure Pneumatic Air Actuator , Air Torque Spring Loaded Double Acting Actuator​

 

A pneumatic actuator is a tool that converts compressed air into mechanical motion. The actuator type determines whether the motion is rotary or linear. There are many different pneumatic actuator types available on the market.

How does the Actuator Work?

The actuator is made up of several different parts, which include: a piston, cylinder, valve, and ports. A diaphragm encloses the pistons, which helps to keep air in the top section of the cylinder. This allows air pressure to bring power to the diaphragm in a downward motion, which moves the piston underneath. When the piston reaches this area the valve stem moves causing the actuator’s internal pieces to move. Each different type of Actuator is capable of a specific application:

 

Pneumatic actuator working principle

 

1, double acting actuator
A port intake, B port exhaust, push the two pistons separately to the two B port intake, A port exhaust, push the two pistons close to the center
While moving, the output shaft turns the valve counterclockwise to open the heart, and the output shaft rotates the valve clockwise to close.

2, single acting actuator
A port intake, B port exhaust, push the two pistons separately to the two exhaust or power loss, the spring pushes the two pistons close to the center
While moving, compress the spring at the same time, the output shaft moves counterclockwise, and the output shaft rotates the valve clockwise to close.
Turn to the direction. Valve open

Precautions

 

 When performing large-scale inspections of actuators, it is necessary to completely discharge the remaining pressure in the pipeline.
When the actuator is in operation, do not step into the transmission or place your hand in the transmission.
To prevent an electric shock, do not touch the wire connection (exposed live body) on the actuator with the solenoid valve or switch.
Be sure to test in the event of a power outage. Also, do not touch these charged bodies with wet hands.

 

Pneumatic valve accessories

 

Annex 1 Reversing solenoid valve
The electronic control operation for "turning on" or "off" the pneumatic valve acts as a switching air source. The solenoid valve complies with the NAMUR connection standard and can be divided into a mounted type and a separate type. The double-acting pneumatic actuator is equipped with a two-position five-way solenoid valve, and the single-acting two-position three-way solenoid valve can be manually operated. The structure is simple, compact and has a long life. The solenoid valve coil voltage has AC220V or DC24V low power consumption, and the explosion-proof encapsulation Ex m II BT4 and the explosion-proof Ex d II BT4 are optional. The company's solenoid valve is directly mounted on the actuator in a plate type.

Common faults and handling

 

 

Stage Fault Description Fault Cause Remedy
I/P check I/P air pressure output does not change Gas source failure Check if the air supply valve is open
      Check if the pipeline is blocked
    Control signal failur Check if the signal line is disconnected
      Control signal line "+" "-" is reversed
    I/P damage replacement
Adjustment valve The regulating valve will not move or the action will not be in place No air source Check if the air supply valve is open
    Gas circuit connection is incorrect Check the correctness of the gas circuit connection
    Gas circuit blockage Check and ventilate the circuit
    Give way Check for leaks and fix
    Adjustment valve stuck Contact the aircraft to solve
    Regulating valve and accessory connection is not strong Check the connection of the regulating valve and accessories, it should be fixed firmly, no looseness
    I/P failure Check I/P
    Solenoid valve is not powered or de-energized Check solenoid valve power
    Valve not in automatic position Switch to automatic position
    DCS has a mandatory signal Contact run processing
    Some valves must be reset to the local after losing gas. Local reset
  Position transmitter current output is not allowed Not securely connected to the regulating valve Check the connection, it should be fixed firmly, no looseness
