Dispositivo de control de temperatura del calderín de reacción a prueba de explosiones

Explosion-proof reaction kettle temperature control equipment is a commonly used temperature control equipment in the pharmaceutical chemical industry and laboratory. During the operation, we need to pay attention to its correct use method. Now I will give you a brief introduction.

1. Although the temperature control equipment of the explosion-proof reaction kettle has perfect measures to prevent electric shock, we should pay special attention to the control system of the electrical appliance, and do not touch the electrical part under the working condition.

2. First observe whether the refrigeration compressor can be started during the operation of the equipment. If the compressor can be started during the operation, it means that the main power supply to the electrical circuits are all normal, and there is no problem with the electrical system.

3. When there is no problem with the electrical system, continue to check the refrigeration system. Check the refrigeration compressor unit first. If the exhaust and suction pressures of the low-temperature stage compressor are lower than the normal values, and the suction pressure is in an evacuated state, it means that the amount of refrigerant in the main refrigeration unit is obviously insufficient. Then touch the exhaust and suction pipelines with your hands. If you find that the temperature of the exhaust pipeline is not high, and the temperature of the suction pipeline is not low (not frosted), this also shows the lack of refrigerant in the main unit. .

4. It is forbidden to experiment with flammable, explosive, and highly corrosive items, and do not carry and maintain them in the power-on state and during operation.

5. The refrigeration system of the temperature control equipment of the explosion-proof reaction kettle adopts a refrigeration system composed of a fully enclosed compressor, and the cycle is repeated to achieve the purpose of cooling. output to achieve a dynamic balance.

6. PID coordinated control is adopted, and the output power is calculated by microcomputer. In order to achieve fast heating rate and high temperature, generally increase the number of heating wires and improve the control performance of temperature control software.
