Extending the life of your vacuum furnace through preventive maintenance will result in decreased downtime and increased productivity.
Every Three Months
Variable Reactance Transformers (VRT)
⬜ Inspect all VRT resistors.
⬜ Inspect secondary power cables to the VRT for wear.
⬜ Ensure that all cables to and from the VRT have tight connections.
Voltage & Amperage
⬜ Inspect the setting of the blower blast gate to avoid exceeding motor amperage ratings (applicable for Ipsen MetalMaster/HR models).
Wiring & Fuses
⬜ Inspect the wiring on all cabinets and junction boxes.
⬜ Inspect all fuses for continuity.
⬜ Inspect bottom-head or door alignment to tank flange.
⬜ Ensure that the bottom-head motor and the gearbox shafts are aligned.
⬜ Test control and overtemperature thermocouples for proper response and direction.
Every Six Months
⬜ Replace load thermocouples regardless of appearance. If the vacuum-indicating instrument shows a possible malfunction in the sensing head, apply corrective actions and replace the vacuum-sensing head.
- NOTE: Keep spare sensing heads on hand at all times.
⬜ If you have a paper chart recorder, clean and lubricate the chart drive mechanics and slide-wire mechanism.
- NOTE: This step is only applicable if you have an older furnace as newer ones are mostly digital.
⬜ Check the temperature, calibration and stability on your test instruments.
