The high-pressure reactor should be used at the designated location and operated according to the instructions. Identify the test pressure, usage pressure, and maximum usage temperature conditions engraved on the main container, and use them within their allowable range.
　　
The high-pressure reactor is a precision equipment that uses a conical contact sealing form through a sealing ring, and achieves sealing by tightening the main bolt to press them against each other. Special care must be taken for the sealing cone surface to avoid damage caused by various collisions. When installing the cover, first place the reaction kettle body, then carefully install the kettle cover in a fixed position on the kettle body. When tightening the main bolts, they must be tightened diagonally and symmetrically in multiple steps, with even force. The kettle cover is not allowed to tilt to one side to achieve good sealing effect, and the specified tightening torque should not be exceeded to prevent the sealing surface from being squeezed or accelerated wear.
　　
The pressure used by the pressure gauge should be within 1/2 of its indicated pressure. And often compare the pressure gauge with the standard pressure gauge and calibrate it.
　　
Oxygen pressure gauges should be avoided from being mixed with pressure gauges used for other gases.
　　
Safety valves and other safety devices must use instruments that have undergone regular inspections and meet the specified requirements.
　　
Attention must be paid during operation to accurately insert the thermometer into the reaction solution.
　　
The interior and lining parts of the high-pressure reactor should be kept clean.
　　
When covering the disc flange cover, the bolts located on the diagonal should be tightened in pairs in sequence.
　　
When the measuring instrument ruptures, most of the time it breaks on both sides of its glass surface. Therefore, do not stand in these dangerous places during operation. When danger is expected, the glass should be removed and replaced with a new one.
