Safe operation rules of arch breaker you should know

The compressed air supply system of air gun should adopt centralized air supply to ensure the stability of pressure and minimize the loss of air source. In order to give full play to the performance of the air gun and achieve the purpose of breaking the arch, clearing the blockage and assisting the flow, the correct operation and good maintenance are extremely important. How to operate and maintain correctly? Xiaobian is here today to take you to learn.

1、 Operation procedure

After the installation of the air gun, it should be carefully checked. If there is no problem, it should be inflated to the air gun, and the seal should be checked. The air test can be carried out only after it is qualified, and the normal working pressure should be gradually increased during the trial release.

1. The air gun should be in the charge of a special person and must not be operated at will;

2. Ensure that the feeder and bin gate have been started or opened before air gun operation;

3. Before use, the blocking position in the silo should be checked, and then it should be released by stages and layers according to the specific situation of the silo blocking;

4. The release of air gun should start from the lowest layer and go up in sequence, with an interval of more than 10 seconds. Avoid the upper material tamping the lower material;

5. For manual control, the operation time of the button shall not be less than 1 second. The interval between two operations of the same air gun should be more than 60 seconds;

6. Before use, the pressure inside the gun body should be checked to be above 0.3MPa (working pressure 0.3-0.8mpa);

7. It is not allowed to start the air gun under the condition of normal material flow to avoid tamping the material and causing material blockage;

8. When the ambient temperature is lower than - 20 ℃, do not inflate the air gun;

2、 Safety precautions

1. When using, the personnel should be far away from the coal chute of the silo;

2. If manual cleaning or other maintenance work is needed in the silo, make sure that the main air inlet valve is closed, there is no compressed air in the gun body, and the control power supply is disconnected;

3. During the maintenance of the air gun, it should be confirmed that there is no compressed air in the gun body and the control power supply has been disconnected;

4. Before the air gun is fixed on the silo, do not put it on trial at will;
