How to deal with the failure of the hot air circulation oven during use?

The hot air circulating oven is made of high quality mirror stainless steel (or drawing plate) by argon arc welding. The box is made of high quality steel plate and the double row digital expression microcomputer PID temperature controller. The temperature expression is intuitive and the temperature control is reliable. The overall system of the blast circulation consists of a centrifugal wind wheel and a guiding air duct that can operate at a high temperature, and the temperature inside the box is evenly controllable. The whole system of temperature limit alarm, the temperature is higher than the frame temperature, and the heating is actively stopped.
The domestic hot air circulation oven has reached the advanced level through several upgrades. It uses steam or electricity as a heating object, and uses an axial fan to heat the air in a convection manner. The hot air layer flows through the baking tray and the material is passed through the calorie. Fresh air enters the hot air circulation oven from the air inlet to supply and then discharges from the moisture exhaust port, continuously replenishing fresh air and continuously discharging hot and humid air, so as to maintain the proper relative humidity in the hot air circulation oven. The unique place of this hot air circulation oven is that most of the hot air is circulated in the box, thus increasing the heat conduction and saving energy substances.
Hot air circulation hot air circulation oven is a general-purpose drying facility. It is suitable for use in a wide range of pan-type intermittent drying facilities. It is used in the raw materials of pharmaceutical, chemical, food, light industry and heavy industry, and the heating and dehumidification of products.
The hot air circulation oven is a little tight and unique, and needs attention during the application process.
1. The hot air circulation oven should be placed in a clean and tidy indoors. Keep it dry, keep moisture and moisture, and avoid corrosion.
2. There must be a certain space for the hot air circulation oven to be placed. The southeast and northwest should have a certain distance from the wall. It is proposed to have more than 0.6 meters.
3. Check the voltage before use. The voltage required for the smaller hot air circulation oven is 220V. Install a sufficient capacity of the power supply knife according to the power consumption of the hot air circulation oven. Also, use a suitable power cord. You should also do a grounding line office.
4. After the above office number is ready, the product can be placed in the hot air circulation oven, and then the power supply is connected, the hot air circulation oven switch is turned on, and the hot air circulation oven with the air blowing device is sure to be heated during the heating process. The blower is turned on. If the blower is not turned on, the motor may be burned and destroyed, and the heating element may be destroyed. Immediately adjust the temperature of the appropriate product baking, the hot air circulation oven enters the office.
5. The baked products should not be arranged too densely. It should not be too close to the surrounding, so as not to affect the hot air circulation. It is strictly forbidden to bake flammable, explosive things and volatile and corrosive things.
6. After the bake is finished, cut off the power supply, and then open the office door. Remember that you can not directly touch the baked things with your hands. Use special tools or things with insulated gloves to take the baking. To avoid burns. Or wait for the indoor temperature to cool, and then take the product.
7. The hot air circulation oven should be kept clean and tidy.
8. When using a hot air circulation oven, the temperature should not exceed the upper operating temperature of the hot air circulation oven. Customers with special requirements can purchase special hot air circulation ovens, such as explosion-proof hot air circulation ovens, high temperature hot air circulation ovens, flammable gas hot air circulation ovens, etc.
There are several problems that the hot air circulation oven is easy to reveal during the application process:
1. Hot air circulating oven power supply failure: When the power supply fails, please check the specifications of the external power supply, and the accessories are not good.
2. The hot air circulation oven temperature is not normal: When the temperature operation problem occurs, please check if the temperature setting is wrong. When abnormal temperature occurs, please check the over-temperature care and contactor. Is the solid-state replacement device bad?
3. Hot air circulation oven hair dryer: Check if the contactor is not good. Check if the motor is not good. Check if the wind wheel is peeling off. Check if the power phase is not good.
