1. Installation location.
Laboratory glass reactors should be installed in a room that meets the requirements of national safety management. When using multiple reactors, they should be placed separately. Each operating room should have a channel and outlet leading to the outdoors. When there is an explosive medium At the same time, it should ensure that the ventilation effect of the enterprise equipment is good.
2. The installation and sealing of the kettle body and the kettle cover.
The kettle body and the kettle cover adopt the line contact between the washer or the cone surface and the arc surface, and they are pressed against each other by tightening the main nut to achieve a good sealing effect. When tightening the nut, it must be symmetrical diagonally, and gradually tighten several times with uniform force, and the kettle cover is not allowed to tilt to one side to achieve a good sealing effect.
3. Installation of valves, pressure gauges and safety valves
By tightening the two nuts on the front and the back, a sealing effect is achieved. We must not use relative free rotation on the arc sealing surfaces connecting the two ends. When assembling all fixed screw joints, lubricant or oil blended graphite must be applied. , so as not to be killed.
4. Pressure maintenance inspection
After installing the equipment, keep the vacuum pressure for 30 minutes to check whether there is a large leak. If there is a leak, please use soap foam to find the pipeline and the leakage point of the pipeline. After finding out the ventilation and 5. Kettle body cleaning
After the reaction is completed, the temperature is first lowered, and then the gas in the kettle is released to the outside through the pipeline, so that the pressure in the kettle is reduced to normal pressure. Disassembly under pressure is strictly prohibited! Then loosen and remove the main bolts and nuts symmetrically, then carefully remove the lid and place it on the stand.
