There are several main reasons for the overload operation damage of the pneumatic actuator

A key problem of pneumatic actuator damage is load. Its load situation mainly has the following types:

1, the torque constraint organization of the setting value is not correct, the suspended torque is less than its setting value, resulting in a continuous generation of excessive torque, so that the motor stops rolling.

2. For some reasons, the torque constraint organization circuit fails, resulting in excessive torque.

3, the use of ambient temperature is high, relatively reduce the heat capacity of the motor.

4, the voltage of the power supply is too low, so that it can not obtain the required torque, forming the motor to stop rolling.

5, continuous use, the heat storage generated exceeds the allowable temperature appreciation of the motor.

Generally, the motor will not be overloaded when working within a predetermined time. The maintenance measures for the load condition of the pneumatic actuator are mainly as follows:

1, through the selection of thermal relay to maintain the motor locked-rotation.

2, after the selection of thermostat to the motor continuous work or electric operation of the overload maintenance.

3, after the selection of fuses or overcurrent relays can be useful to avoid short circuit incidents.
