1. When inflating to build pressure, when the pressure in the tank is too high and the safety valve is opened, the exhaust valve can be opened to reduce pressure;
2. When water enters the tank, the water should be discharged in time through the two drain valves at the bottom of the tank. If the canvas of the fluidized bed is wet,
The fluidized bed canvas should be replaced in time to avoid cement agglomeration on it;
3. During the unloading process, if other abnormal conditions occur and the unloading needs to be terminated, the unloading disc valve can be closed first, and then the pressure in the fluidization chamber can be released by opening the exhaust valve.
