Section 3:Utilize
1、 Please provide the Chinese content to be translated.CO2The steel cylinder is connected to the cooling coil within the cold bath.
2、 Turn on the cold bath power supply for cooling. Refer to the cold bath instructions for usage details.
3、 Turn on the cold bath external circulation power supply, coolCO2Pump head.
4、 Set on the electrical contact pressure gaugeCO2Pump upper limit protection pressure: The pump will automatically shut off for protection when the pressure reaches the upper limit. After the pressure drops, simply reset the switch to restart the pump.
5、 Open the valve on the reactor.CO2Pump power, inject into the reactorCO2。
6、 Turn on the reactor heating switch, set the heating temperature on the temperature controller, and the controller will automatically control the reactor's temperature rise until it reaches the set temperature, then maintain a constant temperature. For instructions on using the temperature controller, please refer to the temperature controller's user manual.
7、 Turn on the agitator power switch, adjust the speed control knob, and the motor stirs the medium inside the mixing vessel at a certain speed.
8、 The pressure of the reaction kettle is measured by a pressure gauge, with manual readings.
Section 4: Safety
Manufacturer reminds operators to pay attention to the following points:
* Ensure correct power input for all instrument gauges.
* All parts of the instrument are guaranteed to have good grounding.
* Flow line pressure in all sections must not exceed the design pressure, especially not higher than the range of various measuring instruments. Extra caution must be exercised when using gas to increase pressure.
* The instrument's valve is designed for manual operation. Please pre-design the test process route according to the test steps. Any incorrect operation of a valve can lead to the failure of the entire test.
* The system must be operated with insulating gloves during high-temperature operations to prevent burns.
Special attention: When heating, due to the expansion of the liquid, the pressure increases. Always monitor the liquid pressure inside the container to prevent it from becoming too high and exceeding the container's operating pressure.
