Small knowledge of the use of reactor heating temperature control

Reactor heating temperature control is a fully enclosed system
consisting of a refrigeration compressor, condenser, filter drier, capillary and evaporator welded by copper tubes.

1, in the system is filled with a certain amount of refrigerant, it under the action of the compressor, the evaporator absorbs the heat of the low-pressure low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, into the condenser cooling liquefaction, the formation of refrigerant, in the refrigeration system continuous circulation, to achieve the purpose of refrigeration, refrigeration compressor is fully enclosed, is to make the refrigerant to maintain the power
of circulation.

2, the electric heater is installed in the inner part of the body near the lower position of the fuel tank, and the side of the electric heater is provided with an oil pump, the side of the oil pump is provided with a cooler, the side of the solenoid valve is provided with a filter, and the internal of the solenoid valve is provided with a coolant inlet in the rear position of the body, the coolant inlet is provided with a heating liquid outlet, the lower part of the heating liquid outlet is provided with a coolant outlet, and the end of the temperature alarm is set with a temperature-sensitive head.
And the temperature alarm side near the upper end of the tank is provided with an oil filling port, the electric heater is provided with a heating tube, the electric heater, oil pump, cooler, solenoid valve and temperature alarm are connected
to the control panel through the wire.

3.
The cooling method is divided into direct cooling and indirect cooling
.

The indirect cooling method uses the cooling circuit to separate the main circuit, while the direct cooling method directly involves the cooling circuit in the
main circuit.

Water-carrying type hot and cold water circulation machine usually adopts direct cooling method
.

The oil-carrying type hot and cold water circulation machine, because during the heating process, water and oil can not be mixed together, so they all use indirect cooling methods, and their practices usually use plate exchangers for cooling
.

4.
Before use, we must strictly follow the rules and regulations to operate this product
.

Before operation, it should be carefully checked for abnormalities, and in normal operation, the terminals on the upper cover and the contact plate should not be opened to avoid electric shock; Pressure operation is strictly prohibited; In the process of pressure testing, carefully observe the changes in the pressure gauge, reach the test pressure, and immediately close the valve switch; The heating rate should not be too fast, and the pressurization should also be carried out slowly, especially the stirring speed, and only the slow rise is allowed
.

5, when heating to a higher temperature, do not contact with the kettle body, so as not to burn, the experiment should be cooled down first, not rapid cold, in order to prevent damage caused by excessive temperature difference pressure, while timely unplugging the power supply
