What Are The Abnormal Operation Test Methods For The Inflation Shaft?

The purpose of the abnormal operation test of the air-expansion shaft manufacturer is to improve the reliability of the system and avoid undue accidents as much as possible. The abnormal operation test can be carried out as follows:

1. External sudden power failure experiment. When the device is operated manually or automatically, no matter under any circumstances, the sudden power-off of the external can be reliably stopped, and the device can be restored to normal operation by the specified operation steps.

2. Emergency breaking test. When the device is running manually or automatically, no matter what the circumstances, for emergency disconnection operation (such as pressing the emergency stop button on the control panel), the device can be reliably stopped and the normal operation can be resumed through the specified operation steps. .

3. Detect switch failure test. Consideration should be given to the possibility of system detection switch failure, especially for components that are prone to collision, interference, and safety of mechanical components, and abnormal tests should be performed on signals such as end-of-stroke detection. It must be ensured that even if a certain detection switch is defective or damaged, it still does not. A safety incident will occur.

4. Perform no residual bad tests. Consideration should be given to the possibility of system failure, especially for actuators that are prone to mechanical collisions, interference, and safety. The abnormality test should be carried out, and it must be ensured that even if a certain actuator is defective or damaged, it will not occur. Security incident.

5. Protection circuit action test. The possibility of the protection circuit of the system should be considered. Especially for protection devices such as circuit breakers and automatic switches, it should be tested abnormally. It must be ensured that the device can be reliably stopped when the protection device is operated, and the specified operation steps can be used. Resume normal work.
