Introduction to the daily troubleshooting of benchtop resistance furnaces The benchtop resistance furnace is one of many resistance furnaces, so let's learn about the official content about the daily troubleshooting of benchtop resistance furnaces
.
1.
The resistance furnace does not heat up 1.
When the power supply voltage and the controller are working normally, the ammeter does not display, and the general fault is that the electric furnace wire is broken
.
2.
If the power supply voltage is normal and the controller cannot work, you can repair the switch, fuse and furnace door switch inside the controller
.
If the furnace door of the resistance furnace is not closed and the controller cannot work, please refer to the controller manual for the maintenance method of the controller failure
.
3.
When the electric furnace is not connected, it works normally, but when it is connected to the electric furnace, it does not work normally, and the controller emits continuous rattling sound.
The reason is that the voltage drop of the power supply line is too large or the socket and the control switch are not in good contact, which can be adjusted or replaced
.
Second, the resistance furnace heats up slowly 1.
The power supply voltage is normal, and the controller works normally.
The common fault is that some electric furnace wires are open circuited, which can be checked with a multimeter and replaced with electric furnace wires of the same specification
.
2.
The power supply voltage is normal, but the working voltage of the electric furnace is low.
The reason is that the voltage drop of the power supply line is too large or the contact between the socket and the control switch is not good.
It can be adjusted and replaced
.
3.
The power supply voltage is lower than the normal voltage, and the heating power of the electric furnace is insufficient when working
.
The three-phase power supply is out of phase, which can be adjusted and repaired
.
3.
The temperature of the resistance furnace is abnormal 1.
The thermocouple is not inserted into the furnace, causing the furnace temperature to be out of control
.
2.
The graduation number of the thermocouple is inconsistent with the graduation number of the temperature control instrument, which will cause the furnace temperature to be inconsistent with the temperature displayed by the temperature control instrument
.
The above is the relevant introduction about the daily troubleshooting of the benchtop resistance furnace.
I believe that everyone has a corresponding understanding of this after reading, and understanding the corresponding content in advance will be of great help to the future operation.
I hope it will be helpful to everyone.
