Note: 1, the pressure kettle belongs to the meticulous equipment, through the sealing ring using the cone surface contact sealing form, by tightening the main bolts so that they press each other to achieve the purpose of
sealing.
The sealing cone surface must be specially taken care of to avoid various collisions that may cause damage
.
When closing, first place the reactor body, and then the kettle cover according to the fixed position, carefully installed on the kettle body, when tightening the main bolt, it must be diagonally and symmetrically divided into multiple times gradually tightened, the force should be uniform, do not allow the kettle cover to tilt to the side, in order to achieve a good sealing effect, can not exceed the specified tightening torque, in order to prevent the sealing surface is squeezed or accelerated wear; 2.
After each operation, the residue on the kettle body and the kettle cover should be removed, and all the sealing surfaces on the pressure kettle should be cleaned frequently and kept dry, and it is not allowed to clean with hard objects or soft objects with rough surfaces; 3.
The operation reactor should be strictly used in accordance with the "safe use procedures of high-temperature and pressure-resistant reactor", and the operation reactor shall not be operated separately, and more than two people should be required during the experiment; 4.
During the work of the pressure kettle, open the ventilation fan to ensure good ventilation; 5.
When there is pressure in the kettle, it is strictly forbidden to twist the nut or knock on the pressure resistant kettle; 6.
The front and back nut connection (the intake pipe, exhaust pipe and the branch pipe connected by the pressure gauge and the kettle cover) are only allowed to rotate the nut, and the two sealing surfaces shall not be rotated relative to each other; 7.
Observe the indication of the pressure gauge at any time during operation, and strictly prohibit the use of the kettle under the condition of overtemperature and overpressure; 8.
If there is air leakage in the experimental process, immediately stop heating, stop the experiment, and strictly prohibit high temperature twisting of the nut
.
