The Built-in Gas-increasing Shaft Cannot Be Widely Used And The Reason Why It Cannot Work Normally

In recent years, the application of the tunnel-type gas-increasing shaft is basically a large enterprise, a manufacturer of higher-grade products and some enterprises pursuing quality and efficiency. However, what causes most small and medium-sized enterprises to not be widely used?

1. The propaganda of the manufacturer is not enough, and the supporting services are still insufficient.

2. Due to the low grade of the enterprise products, the requirements for printing and slitting are not high. The ordinary air-expansion shaft and the mechanical slip shaft can meet the basic requirements for use, and the production scale of the enterprise is not large, the production pressure is not large, and there is no desire for urgent improvement. And failed to apply.

3, due to the slippery shaft in the past few years, there is no domestic manufacturer, all rely on imports, the price is expensive, and the use of the company to cause greater economic pressure and give up.

4. Most air-expansion shaft manufacturers do not know enough about the performance difference between the sliding air-expansion shaft and the mechanical slip shaft, and the ordinary air-expansion shaft. In particular, the maintenance ratio of the air-expansion shaft of the slip air shaft and other shafts is not clear. The understanding only believes that the price of the sliding air shaft is relatively high, and the company has no urgent requirements for maximizing the efficiency of the products, which hinders the enthusiasm of its application.

In order to improve production efficiency, the normal operation of the inflation shaft is also very important. Therefore, in the normal case of using the inflation shaft, the following points should be understood. This is very important.

1. Check if the switch is not in good contact. 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.

2. The external power is suddenly turned off. When the equipment is operated manually or automatically, no matter under any circumstances, the sudden power-off of the external can be reliably stopped, and the air-expansion shaft device can be restored to normal operation by the specified operation steps.

3. Pay attention to the protection circuit action. 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.

4, emergency break test. When the equipment is operated manually or automatically, the air shaft can be reliably stopped for emergency disconnection (such as pressing the emergency stop button on the control panel) under any circumstances, and can be reliably stopped by the specified operation steps. Resume normal work.

5. The actuator is defective. Consideration should be given to the possibility of system actuators being defective, especially for actuators that are prone to mechanical collisions, interference, and safety effects. Anomaly detection should be performed to ensure that even if an actuator is defective or damaged, no safety accident will occur. .
