Abnormal Operation Test Procedure For Gas Rising Shaft

The purpose of the gas up shaft abnormal operation test is to improve system reliability 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, detection 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, actuator failure test
Consideration should be given to the possibility of system actuators being defective, especially for actuators that are prone to mechanical collisions, interference, and affect safety. Anomaly tests should be performed to ensure that even if an actuator is defective or damaged, no safety accident will occur. .

5, protection circuit action test
The possibility of the protection circuit of the gas-up shaft system should be considered, especially for protection devices such as circuit breakers and automatic switches, and abnormal tests should be carried out to ensure that the device can be reliably stopped and the specified operation is performed when the protection device operates. Steps can resume normal work.
