Introduction of the principle of electric vacuum drying oven

August 24, 2021

The outer surface of the electric vacuum drying oven is stamped and welded by steel plate, and the surface of the outer casing is treated with high-strength electrostatic spray coating, and the paint film is smooth and firm. The studio is made of carbon steel or stainless steel, and the insulation between the studio and the outer casing is filled with insulation cotton. A sample shelf is placed inside the studio for placing various test items, and a mica heater is placed around the outside of the work wall. The door seal is sealed with a silicone rubber strip, and a sight glass for observation is provided on the door. The evacuation and inflation of the electric vacuum drying oven are controlled by a solenoid valve. The electrical box is on the left or the lower part of the cabinet. The front panel of the electrical box is equipped with a vacuum gauge, a temperature control instrument and a control switch. The electrical box is equipped with electrical components.

The electric vacuum drying oven maintains a certain degree of vacuum in the working chamber and uses an intelligent digital temperature controller for temperature setting, display and control. The temperature regulator uses computer technology to collect and process the temperature signal in the working chamber, so that the temperature in the working chamber can be automatically kept at a constant temperature. The temperature control system is PID intelligent temperature control, reliable performance and convenient to use.

Intelligent temperature regulators have over temperature protection. When the temperature in the working chamber exceeds the set temperature value during the operation of the device, the over-temperature protection circuit operates to cut off the heating circuit.
