Daily maintenance of high-pressure reaction kettle in hydrofluoric acid system:

1. Check for corrosion on the reactor body: Check for cracks, bulges, deformation, corrosion, perforation, leakage, and other phenomena on the high-pressure reactor body. Check for intact insulation, paint, and any signs of detachment or burning.

2. Check for any abnormal noise during operation: Listen for the sound of the reducer and motor to see if it is normal. Touch the driving temperature of various parts such as the motor, reducer, and machine base bearings. The general temperature should be ≤ 40 ℃, and the maximum temperature should be ≤ 60 ℃. Listen for abnormal noise: Regularly listen for any abnormal vibrations and sounds inside the high-pressure reactor.

3. Check lubrication and sealing: Regularly check for oil leakage in the reducer, whether the shaft seal is intact, and if necessary, add or update the corresponding oil (oil hot high-pressure reaction kettle).

4. Check safety devices: Check whether safety devices such as safety valves, pressure gauges, explosion-proof membranes, thermometers, etc. are accurate, flexible, and easy to use, whether safety valves and pressure gauges have been calibrated and sealed properly, whether the red line on the pressure gauge is drawn correctly, and whether the explosion-proof membrane is leaking inside.

5. Check the mixing shaft: Keep the mixing shaft clean and visible. For the shaft connected by the round nut, check whether the rotation direction of the mixing shaft is clockwise, and it is strictly prohibited to reverse. Check bolts and shields: Check for loose bolts on the flange and base of the high-pressure reactor, and ensure that the safety shield is intact and reliable.

6. Maintain equipment hygiene: Keep the high-pressure reactor clean, ensuring no oil stains, the equipment is in its natural color, and the sealing surface is clean to ensure the normal operation of the high-pressure reactor.
