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

The box of hot air circulation oven is made of mirror stainless steel (or wire drawing plate) by argon arc welding The outside of the box is made of steel plate The double row digital expression micro-computer PID temperature controller is intuitive in temperature expression and reliable in temperature control The whole system of blast circulation is composed of a centrifugal wind wheel and a guide air duct which can run in one continuous air under high temperature, and the temperature in the box is even and controllable The overall system of temperature limit alarm, which actively stops heating when the temperature is higher than the frame temperature The domestic hot air circulation oven has reached the advanced level through several shifts It uses steam or electricity as the heating object, and uses axial flow fan to heat exchanger to heat air in the form of convection The hot air layer flows through the baking tray and carries out calorie transfer with materials The fresh air enters the hot air circulation oven from the air inlet for replenishment, and then is discharged from the dehumidification outlet The fresh air is continuously replenished and the hot and humid air is continuously discharged, so as to maintain the appropriate relative humidity in the hot air circulation oven The unique feature of the hot air circulation oven Zui is that most of the hot air circulates in the oven, so it increases heat conduction and saves energy materials The hot air circulation hot air circulation oven is a general drying facility, which is suitable for a wide range of applications It is a tray type intermittent drying facility, and is used for heating and dehumidification of raw materials and products in pharmaceutical, chemical, food, light and heavy industries Hot air circulation oven is a special place that is a little closed Attention should be paid in the process of application 1 Hot air circulation oven should be placed at a clean and tidy level in the room It should be kept dry, moisture-proof and moisture-proof, and avoid corrosion 2 There should be a certain space where the hot air circulation oven is placed There should be a certain distance between the southeast, northwest and the wall It is suggested that there should be more than 0.6m 3 Check the voltage before use The voltage required for the smaller hot air circulation oven is 220V Install the power switch with sufficient volume according to the power consumption of the hot air circulation oven Besides, proper power supply wire shall be selected The grounding wire office should also be done well 4 After the above office number is ready, the product can be put into the hot air circulation oven, then connect the power supply, turn on the hot air circulation oven switch, and the hot air circulation oven with the blower device must be turned on in the process of heating to the constant temperature If the blower is not turned on, the motor may be burned and destroyed, and the heating elements may be destroyed Then adjust the appropriate product baking temperature, the hot air circulation oven will enter the office 5 The baked products shall not be arranged too closely or too close to the surroundings, so as not to affect the hot air circulation It is strictly prohibited to bake inflammable, explosive and volatile and corrosive things 6 After baking, cut off the power supply first, and then open the public room door Keep in mind that you can't touch the baking directly with your hands Use special tools or insulated gloves to take the baking things, so as to avoid burns Or wait for the indoor temperature to cool, and then take the raw product 7 The office of hot air circulation oven shall be kept clean 8 When using the hot air circulation oven, the temperature shall not exceed the top application temperature of the hot air circulation oven Customers with special requirements can purchase special hot air circulation oven of Kunshan Taishun enterprise, such as explosion-proof hot air circulation oven, high temperature hot air circulation oven, combustible gas hot air circulation oven, etc.
