Operational points for the operation of the double door hot air circulation oven

The double-door hot air circulation oven continuously circulates hot air in the box by means of the air circulation system fan circulating air. The motor drives the wind wheel to continuously circulate the air through the heater, and the hot air passes through the air passage to reach the oven room, and then sucks after use. The air passage is air circulation. After the zui, the oven can be used to achieve a relatively constant temperature using the Hui melting material inside the silicon crystal.

Operating points of the two-door hot air circulation oven :

1. Explosive, flammable and volatile materials should not be placed in the box, so as not to cause an explosion.

2. The uniform load of the sample shelf should not exceed 20kg.

3. No objects can be placed on the shelf between the sample chamber and the heating chamber, so as not to affect the heat exchange.

4. Before use, it is necessary to reflect on whether there is stacking or short circuit of nickel wire.

5. The reason why the heating indicator does not light up:

1 bulb is broken;

2 bad bulb contact;

3 heating and breaking the problem.

6. Open the heating switch, the reason for not heating:

1 nickel-chromium wire breaking;

2 switch and line desoldering;

3 temperature control knob refers to the zero position (rotate the temperature control knob to the specified temperature scale);

4 relay protection.

7. The reason why the temperature of the double door hot air circulation oven is mastered is:

1 temperature probe protection (change the thermistor);

2 relay protection;

3 temperature control system and other parts of the problem (available with a universal meter).
