Hot air circulation oven maintenance methods and purchase considerations

Hot air circulation oven maintenance method:

1. Check whether the vents are blocked and clean up the dust.

2. Whether the fan is running normally, the maintenance worker checks whether the current is normal.

3. Check whether the fan is running normally. If it is not accurate, please adjust the static compensation or sensor correction value of the thermostat.

4. Check whether the heating tube is damaged and whether the circuit is aging.

5. Check whether the delay device is accurate and whether the error is allowed.

6. Check whether the circuit and switch are normal.

7. Check whether the motor gearbox is filled with oil

8. It is necessary to carefully observe whether the tightness of the mesh belt is appropriate.

Factors to consider when purchasing a hot air circulation oven:

1. Consider the size of the hot air circulation oven: refers to the production capacity. In terms of appearance, the larger the volume, the stronger the production capacity and the higher the purchase cost.

2. Pay attention to the type of material: The type of material determines the structure and characteristics of the hot air circulation oven. For example, the material is powder, and hot air circulation hot air circulation oven cannot be used.

3. Choose the appropriate structure according to the characteristics of the material: the air circulation system of the hot air circulation oven adopts the fan circulation air supply method, and the air circulation is uniform and efficient.

The air source is a circulating air supply motor, which uses a non-contact switch to drive the wind wheel through the heater to send hot air out, and then to the inner chamber of the oven through the air duct. Use for heating.

4. The temperature uniformity of the hot air circulation oven is an important performance. It is also an important indicator to judge the quality of an oven. In the oven constant temperature stage, although the temperature of the control instrument is generally relatively stable, the temperature of each point in the oven is different, which will cause the samples in different positions to be heated differently.
