Structural Features:

1) Temperature Controller: AI series digital intelligent programmable single-loop regulator with an accuracy of 0.1 class. Multiple curves can be set, each with 15 segments. 1) In high-quality heat treatment processes, the operating time of the heat preservation section can be accurately determined.

2) The temperature measuring thermocouples: N-type armored thermocouples, employing internal temperature measurement.

3) The programmable logic controller (PLC): Siemens S7-200 Smart series, controlling mechanical actions and enabling fully automatic control of vacuuming, vacuum valve opening and closing, heating, movement, and gas filling and discharging.

4) Touchscreen: Provides a clear display of the vacuum furnace's operating status. The vacuum furnace has a self-diagnostic function for faults, and features audible and visual alarms and interlocking protection for water pressure, over-temperature, and over-current issues.

5) Cooling water circuit: a closed-loop circulation system, with flanges, molecular pumps, and other components, all circulated with cooling water for cooling. A water pressure switch is installed on the main return water pipe for real-time monitoring of cooling water pressure. A filter screen is installed at the inlet to filter out coarse impurities in the water.

Delivery Cycle:
