How to properly regulate the operation of high pressure reactor

The high pressure reactor is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food, and is used to complete the process of vulcanization, nitrification, hydrogenation, hydrocarbonization, polymerization, condensation and other processes. It is important to use a high pressure reactor with properly regulated installations.

1. The autoclave should be placed indoors. When equipped with multiple autoclaves, they should be placed separately. Each operating room should have an exit to the outside or the passage, and the equipment should be well ventilated.

2. When installing the kettle lid, the sealing surfaces between the kettle lids should be prevented from colliding with each other. Carefully place the lid on the kettle body in a fixed position. When tightening the main nut, it must be tightened step by step in a diagonally and symmetric manner. The force should be uniform, and the lid should not be tilted to one side to achieve a good sealing effect.

3. For the positive and negative nut joints, only the positive and negative nuts should be rotated. The two arc sealing surfaces must not be relatively rotated. When all the nut pattern couplings are assembled, the lubricating oil should be applied.

4, needle valve line seal, just need to gently turn the valve needle, press the cover tightly, you can achieve a good sealing effect.

5. Turn the rotating body on the kettle by hand to check whether the operation is flexible.

6. The controller should be placed on the console. The working environment temperature is 10-40 °C, the relative humidity is less than 85%, and the surrounding medium does not contain conductive dust and corrosive gases.

7. Check whether the movable parts and fixed contacts on the panel and the rear panel are normal, pull out the upper cover, check whether the connector contacts are loose, and whether there is damage or rust caused by poor transportation and storage.

8. The controller should be grounded reliably.

9. Connect all the wires, including the power cord, the electric furnace wire between the controller and the kettle, the motor wire and the temperature sensor and the tachometer wire.

10. Close the “power” air main switch on the panel and the digital display should display.

11. Set various parameters (such as upper limit alarm temperature, working temperature, etc.) on the digital display. Then, press the “heating” switch, the electric furnace is turned on, and the indicator light on the “heating” switch is on. Adjust the “Voltage” knob to adjust the heating power of the furnace.

12. Press the “stirring” switch, the stirring motor is energized, and the indicator light on the “stirring” switch is on. Slowly turn the “speed control” knob to make the motor rotate slowly. Observe whether the motor is rotating forward. If there is no error, stop the machine. Belt, then restart.

13. After the operation, it can be cooled naturally, cooled by water or placed on the support for air cooling. After the temperature drop, release the pressurized gas in the kettle to reduce the pressure to normal pressure (the pressure gauge shows zero), then loosen the main nut symmetrically, then remove the main nut, then carefully remove the kettle lid and place it. On the stand.

14. After each operation, the residue on the kettle body and the kettle lid should be removed. The main seal should be cleaned frequently and kept clean. Do not wipe with hard objects or rough surfaces.
