The main points of use of laboratory reactor

Shanghai Huotong

The laboratory reactor is used as a chemical reaction vessel. The product has the advantages of safe and reliable use, easy maintenance and wide application range. There are many problems that users need to pay attention to when using the laboratory reactor. Today, the Yanzheng experimental instrument will introduce the ten key points of the laboratory reactor, and hope to help everyone.

1. In the reaction of different media in the reaction kettle, first check whether the medium has corrosion to the main material. The reaction to the moment is intense, a large amount of gas or a high-temperature flammable and explosive chemical reaction, and the reaction of the high-pressure, ultra-high temperature or the medium containing chlorine ions and fluoride ions to the stainless steel are severely ordered!

2. When loading the reaction medium, it should not exceed 2/3 of the surface of the reactor body of the laboratory reactor!

3. It is strictly forbidden to dismantle with pressure when working or at the end! It is strictly forbidden to work under overpressure and over temperature!

4. When cleaning the autoclave, special care should be taken not to allow water or other liquid to flow into the heating furnace to prevent the heating furnace wire from being blown. If heating the jacketed heat transfer oil, be careful not to mix water or other liquids when adding the heat transfer oil. Check the oil level of the heat transfer oil from time to time!

5. If there is abnormal sound inside the isolation sleeve during operation, stop the pressure and check whether the mixing system has abnormal conditions. Regularly check the amount of swing of the stirring shaft. If the amount of swing is too large, replace the bearing or sliding bushing in time!

6. According to the voltage of the controller, connect the corresponding voltage, single-phase 220V, three-phase 380V, the fire and zero lines of the controller should not be connected; do not implement wiring work in the power transmission to prevent electric shock! In order to ensure the controller For normal operation and personal safety of the staff, please connect the grounding wire! The control device itself is not explosion-proof, so avoid the inflammable and explosive environment such as oil and gas!

7. When the final reaction temperature is determined, it is not allowed to change the temperature setting value during the heating process to avoid a large overshoot of the temperature!

8. Under the premise of turning on the power, even if the switch such as heating and stirring is not turned on, the output terminal of the rear panel of the controller is also charged. It is not allowed to pull any plug during operation!

9. The working time display is the internal single-chip 8031. It is timed by accumulating the internal partial frequency. Each time the power is turned off, the internal accumulated data will disappear. In the operation, it should be noted that the working time display is divided into units and the maximum work. The time is 9999 points (166.5 hours)!

10, the speed display correct detection position is essential for the stable display of the speed, this position has been adjusted at the factory, do not adjust at will!
