Pressure measurement and monitoring

1. The high-pressure chamber is equipped with a pressure sensor and connected to the control system for real-time display
On the flange of the high-pressure relief solenoid valve, when the air pressure inside the furnace tube is higher than the set pressure value, the solenoid valve will automatically open to release air, and the chamber pressure will be maintained within the set pressure range.

Equipment usage precautions

1) Connect the gas source, air compressor, and booster pump.
2) Open the right cover and place the materials inside. The cavity should be clean and free of debris.
3) Check the oxygen free copper sealing gasket for high temperature deformation, discoloration, etching, holes, impurities, and the sealing surfaces of the left and right flanges for impurities and etching. If necessary, use alcohol to scrub.
4) Close the right cover and tighten the nut with a torque wrench (the torque of the torque wrench can be adjusted to between 130Nm-160Nm normally).
5) Adjust the intake pressure of the steel cylinder (not less than 5Mpa), adjust the driving gas pressure of the air compressor (constant 0.8Mpa), use a booster pump to increase the gas pressure entering the reaction chamber to 50Mpa, and continue for a period of time to ensure that there is no air leakage in the equipment.
6) When cleaning, first turn on the booster pump, then turn on the exhaust valve. Gas flows in and out to flush the cranial cavity for a period of time. After cleaning, close the exhaust valve first, and then turn off the booster pump.
7) Set sintering process (especially target temperature and set pressure).
8) Start sintering.
9) After sintering is completed and heating is stopped, wait for the material to cool to the appropriate temperature (to ensure that the material does not oxidize and is not burned by high temperatures), manually open the exhaust solenoid valve to release the furnace chamber pressure (be careful not to release pressure at high temperatures, as it may cause danger).
