The vacuum degree does not meet the requirements:
Reason: It may be due to aging seals, air leakage, vacuum pump failure, pipeline blockage, etc.
Solution: Check the condition of the seals, repair or replace them; Check the working condition of the vacuum pump, perform maintenance or replacement; Check the pipeline and clean any blockages.
Uneven heating:
Reason: Heating element aging and damage, temperature control system malfunction.
Solution: Check and replace damaged heating elements, inspect temperature control system sensors and controllers, repair or replace problematic parts.
Unstable furnace pressure:
Reason: Vacuum system leakage, decreased efficiency of vacuum pump, malfunction of vacuum gauge.
Solution: Check the vacuum system and repair the leakage point; Maintain or replace the vacuum pump; Calibrate or replace the vacuum gauge.
Furnace temperature exceeds or cannot reach the set temperature:
Reason: Temperature controller malfunction, damaged heating element, temperature sensor malfunction.
Solution: Check the thermostat, repair or replace it; Check the heating element, repair or replace it; Check the temperature sensor, calibrate or replace it.
Cooling system malfunction:
Reason: Blockage of cooling water circuit, malfunction of cooling pump, malfunction of temperature controller.
Solution: Clean the cooling water circuit, check and maintain the cooling pump, repair or replace the temperature controller.
Electrical system malfunction:
Reason: Unstable power supply, aging electrical components, and control system malfunction.
Solution: Check the power supply to ensure stability; Check and replace aging electrical components; Maintain or upgrade the control system.
Exhaust valve or intake valve malfunction:
Reason: Valve aging, damage, or control system malfunction.
