2. Before opening the steam valve, open the return valve first and then the intake valve. Open the steam valve slowly to preheat the jacket and gradually increase the pressure. The pressure in the jacket cannot exceed the specified value.  
3. The steam valve and cooling valve cannot be started at the same time, and hammering and collision are not allowed when the steam pipeline is passing through.  
4. When opening the cooling water valve, open the return valve first and then the inlet valve. The cooling water pressure shall not be lower than 0.1 MPa or higher than 0.2 MPa.  
5. The water ring vacuum pump should start the pump first and then feed water. When stopping the pump, stop the pump first and then stop the water. There should be no water in the pump.  
6. Check the operation of the reactor and shut down for maintenance in case of any abnormality.  
7. When cleaning the titanium epoxy (enamel) reactor, do not brush the reactor with alkali water, and pay attention not to damage the enamel.
III. after shutdown of stainless steel reactor
1. Stop mixing, cut off the power supply and close the valve.  
2. Cut off the power supply of the mixer, hang a warning sign, and set up a person to monitor.
