The high-pressure reactors of different refrigeration heating systems are different in quality from different manufacturers. However, the same points of attention still need to be noted.
The autoclave configured for different refrigeration and heating systems should be used at the designated location and in accordance with the instructions for use. The conditions such as the test pressure, the use pressure and the use temperature engraved on the main body container shall be determined and used within the permissible conditions.
The high-pressure reaction kettle equipped with the refrigeration heating system is a precision equipment. The sealing ring adopts a tapered surface contact sealing form, and the main bolt is tightened to make them compact against each other to achieve the purpose of sealing. The sealing cone must be specially protected to avoid damage caused by various collisions.
When installing the cover, first place the kettle body of the reaction kettle, then press the kettle lid to the fixed position and carefully install it on the kettle body. When tightening the main bolt, it must be diametrically divided into several times according to the diagonal angle. Uniform, do not allow the lid to tilt to one side, in order to achieve a good sealing effect, can not exceed the specified tightening torque, in order to prevent the sealing surface from being crushed or accelerated wear.
The pressure used in the high pressure reactor pressure gauges of different high and low temperature integrated machine prices is used within 1/2 of the indicated pressure. The pressure gauge is often compared with a standard pressure gauge and corrected. Pressure gauges for oxygen should be avoided in combination with pressure gauges for other gases. For safety valves and other safety devices, use equipment that has been regularly inspected to meet the specified requirements.
When operating high pressure reactors with different refrigeration and heating system configurations, care must be taken that the thermometer is accurately inserted into the reaction solution. The inside of the autoclave and the gasket should be kept clean. When closing the disc flange cover, the bolts on the diagonal line should be tightened in the same pair. When the measuring instrument is broken, most of the cases are broken on the front and rear sides of the glass surface. Therefore, do not stand in these dangerous places during operation. When it is expected that there will be danger, remove the glass and replace it with a new one.
The attention points of the high-pressure reactor are similar, but because the brands of refrigeration heating systems are different, the products brought by them are different, and we need to buy them from regular manufacturers.
