Knowledge of relevant accessories for explosion-proof low-temperature heating units

It is very important for everyone to choose an explosion-proof low-temperature heating unit.
It is not only suitable in terms of price and temperature control range, but also reliable in quality.
We also need to understand the relevant accessories
.


1.
During daily maintenance, the ash layer of the heat exchanger is the place that everyone needs to clean up on a daily basis.
When encountering the ash layer, you can blow it with an air compressor, or use other dusting tools to clean the dust
.

2.
Pay attention to the sound when the device is running.
Once there is an abnormal or sharp sound, it indicates that there must be a problem with the device.
At this time, it is necessary to stop working and check and deal with it immediately
.

3.
When encountering a fault, you must learn basic troubleshooting and judgment.
Generally speaking, you can start the troubleshooting from the power supply.
If the screen does not light up when the power is turned on, it must be a phase sequence protector or a PLC garbled code
.

　　4.
The other is to look at the pressure gauge.
Once the pressure is low, it will alarm, and it will also alarm if it is high.
If it is low, it is definitely abnormal.
In the case of shutdown, the pressure gauge is also very low, or it returns to zero, it must be Air leak
.

　　5.
If the temperature jumps violently or unevenly during operation, it means that the emptying and adding liquid is not done well.
When adding liquid, the exhaust valve is opened when adding liquid, the circulating pump is turned on, and then the exhaust valve Do not turn it off, keep circulating, if the liquid is not enough, continue to add liquid, remember not to close the exhaust valve, and always maintain normal operation
.

6.
The installation of filters in the equipment pipelines is indispensable, which can effectively prevent pipeline blockages, deterioration of heat transfer medium, etc.
, which may cause property damage or related accidents
.

　　7.
The pressure gauge is more critical in refrigeration and heating equipment.
It can pay close attention to the pipeline pressure and find out the pipeline pressure state in time, find out the high and low pressure problems in the pipeline in time, and modify it in time
.

　　8.
Manual valves are added at the connection of the equipment and at both ends of each component installation, so that it is easy to disassemble during maintenance, which can reduce the loss of heat transfer medium, and the relevant valves can be manually closed in time when problems occur
.

　　The accessories of explosion-proof low-temperature heating unit are not only these, of course, there are other accessories.
In order to ensure the stable operation of the equipment, the appropriate temperature range, pressure range, operating environment and other specific knowledge of these components should be fully considered
