Common troubleshooting methods for vacuum sintering furnace

Vacuum sintering furnace as a common sintering equipment, with high temperature, high vacuum working environment, so in the use of the process, some failures may occur. Vacuum melting furnace editor will introduce some common troubleshooting methods below.

Firstly, when the sintering furnace cannot start, firstly check whether the power supply is on, whether the power cord is damaged and whether the switch is on. If all of the above are OK, you can check whether the fuse is blown or the protection device is triggered. If there is a trigger, please replace the fuse or reset the protection device in time.

Secondly, if the heating effect of the sintering furnace is not good, you can first check whether the heating element is damaged, if it is damaged, it needs to be replaced. At the same time, you can also check whether there is a foreign body blockage in the sintering furnace resulting in uneven heating, and you need to clean up the foreign body. In addition, you can also check whether the frequency converter is working properly, whether you need to adjust the frequency or replace the frequency converter.

Again, if the sintering furnace vacuum is unstable or can not meet the requirements, firstly, check whether the vacuum pump is working properly, whether it is necessary to replace the vacuum pump. Secondly, you can check whether the vacuum pipeline has air leakage, need to seal the pipeline or replace the seals. You can also check whether the vacuum gauge is working properly and can be calibrated or replaced.

In addition, if the temperature of the sintering furnace exceeds the set value or the temperature is unstable, you can check whether the temperature control instrument is working properly, and whether it needs to be calibrated or replaced. Also, the temperature sensor can be checked to see if it is damaged and needs to be replaced. Also, you can check if the thermocouple connections are secure and need to be reconnected or replaced.

In addition, if there is a strange noise inside the sintering furnace equipment, you can check whether the transmission parts are out of oil or worn, and need to add lubricant or replace parts. At the same time, you can also check whether the bearing is damaged or the bearing hole is deformed, need to replace the bearing or repair the bearing hole.

There is also a common fault that the sintering furnace equipment can not be stopped normally. Firstly, you can check whether the sintering furnace control system is faulty and whether the control parameters need to be reset. Secondly, you can check whether the stop switch is out of order, and you need to replace the stop switch. In addition, you can also check whether the controller is working properly, whether you need to replace the controller or repair.

In summary, the common troubleshooting methods of vacuum sintering furnace mainly include checking the power supply and switch status, replacing the fuse or resetting the protection device, replacing the heating element, cleaning up the foreign matter, adjusting the frequency of the inverter, replacing the vacuum pump, sealing the pipeline, calibrating or replacing the vacuum gauge, calibrating or replacing the temperature control instrument, replacing the temperature sensor, reconnecting or replacing the thermocouples, adding lubricants or replacing parts, Replace the bearing or repair the bearing hole, reset the control parameters, replace the stop switch, replace the controller or make repairs. For some unsolvable faults, it is recommended to contact the manufacturer or professional maintenance personnel in time for investigation and repair to ensure the normal operation of the equipment.
