How to operate the high-pressure reactor 3

(4) When installing valves, pressure gauges and safety valves, the sealing effect is achieved by tightening the front and back nuts. The arc sealing surfaces at both ends of the connection must not rotate relative to each other. All screw joints must be lubricated during assembly. Use graphite mixed with agent or oil to avoid seizure. Use of valves: The needle valve is a line seal. You only need to turn the valve needle slightly and press the cover tightly to achieve good sealing performance. Do not use excessive force to avoid damaging the sealing surface.
(5) After the equipment is installed, pass in a certain amount of nitrogen and keep the pressure for 30 minutes, and check for leaks. If any leaks are found, use soap foam to find the leak points in the pipelines and pipe mouths. After finding them, release the gas and tighten them. Run the nitrogen pressure holding test again to ensure there is no leakage and then start working normally.
(6) When heating, the heating rate should not be greater than 100℃h, and the heating power should be slowly added from low voltage. When cooling down,
