At present, most of the industrial explosion-proof high and low temperature cycle machines are equipped with all-digital PID temperature, flow control and automatic cooling control, which can automatically maintain a stable mold temperature and have multiple settings
.
Generally, there are two categories of refrigeration and heating
.
They are widely used in various fields of chemical industry and other industries
.
The market of explosion-proof high and low temperature cycle machines in the chemical industry and the application status of the chemical industry.
The rapid development of the chemical industry has brought great opportunities and challenges to the industry
.
Similar to developed countries, it has great advantages compared to the domestic level in terms of technology, experience or processing equipment
.
Of course, this also shows that there is still a lot of room for improvement at the domestic level
.
1.
After checking the accuracy of the pipeline connection between the power supply and the heating equipment, and confirming that all aspects are correct, the equipment can be started.
For the first use, the heating rate should not be too fast, and must be carried out according to the heating curve
.
For example, if the temperature is 300 degrees, the set temperature should be set at 100 degrees, and the heating cycle should be carried out; after the equipment is running normally, the temperature will be gradually heated, with a heating frequency of every 5 degrees.

2.
During the continuous heating of the equipment, the operator should check whether the operating conditions of each heat-using equipment and its process system are in good condition, and check whether the vibration, noise and lubrication are normal
.
3.
At the beginning of normal heating operation, the operator should check whether the equipment and its connecting pipeline valves have the phenomenon of leakage and dripping of heat-conducting oil
.
4.
After stable circulation heating, normal process production is started with thermal equipment.
Operators should pay attention to observe whether the support of relevant equipment, process systems and pipelines is stable to ensure stable production
.
5.
During the normal working process, the operator should always pay attention to the thermal expansion of the relevant equipment and its pipelines
.
6.
During the heating process, check whether the process parameters such as temperature, temperature difference, pressure, pressure difference and flow rate are normal and stable at any time
.
7.
The operator is required to check and record the actions of each electrical instrument and its control alarm device to check whether its function is normal
