Abstract

Vacuum sintering furnace may encounter a variety of faults in the operation process, the following are some common faults and their solutions:

The vacuum degree cannot reach the requirement:

Reason analysis: it may be due to the decline in the performance of the vacuum pump, the existence of leakage points or contamination within the vacuum system.

Solution: Check and replace damaged seals, clean or replace filters; perform maintenance on the vacuum pump, repair or replace if necessary; find and repair possible leakage points.

Temperature control is not stable:

Reason analysis: damaged thermocouple, heating element failure, improper temperature control instrumentation settings.

Solution: Replace the damaged thermocouple or heating element; recalibrate the temperature control instrument to ensure that the parameters are set correctly.

Heating speed is too slow or not heating:

Cause analysis: power supply problems, heating element aging or broken circuit, control system failure, etc.

Solutions: Check for proper power connections and fix any power supply problems; check the condition of heating elements and replace as needed; troubleshoot potential problems in the control system and fix them.

Inefficient cooling:

Cause analysis: blockage of the cooling system, insufficient cooling medium or circulating pump failure.

Solution: Clean the cooling pipes to ensure there is no blockage; replenish the cooling medium to the proper level; repair or replace the faulty circulation pump.

Equipment abnormal noise:

Cause analysis: loose mechanical parts, wear and tear or imbalance.

Solution: Tighten all loose screws and connections; replace worn parts; adjust relevant components to restore balance.

Alarm triggers frequently:

Cause analysis: Sensor failure, limit protection device malfunction, or operating conditions outside the set range.

Solution: Test the function of all sensors and replace them if necessary; check whether the working logic of the limit protection device is correct; make sure that the operating conditions are in accordance with the equipment specifications.  

Regular maintenance is an effective means of preventing many of these problems. In addition, following the manufacturer's operating instructions and safety protocols is essential to ensure long-term stable operation of the equipment. In case of complex technical problems, it is recommended to contact a specialized technician or service provider for assistance.
