7, the heater working life of not less than 1000h; door life of more than 5000 times.
Buy electric oven specific steps are as follows:
1, check the appearance
Cabinet baking paint is smooth and thick without flaking; cavity, baking net chrome layer bright, smooth without flaking; door open and close freely. The frame is easy to dismantle; the heater is firmly installed and can be pulled down with proper force.
2, energized test
Turn on the power, turn the switch to the upper heater energized position, the upper heating lamp is on, 3min later, there should be temperature rise. Then turn the switch to the lower part of the heater energized position, the corresponding indicator light, after a few minutes, the requirements of the temperature rise. Finally, the switch will be placed in the full on position, the box temperature control value will be dialed in the 200 ℃ position, the requirements of the temperature rise to 200 ℃ in 15min.
3, timing check
Timer electric oven, should check the timing time is accurate.
4, constant temperature check
Test 100 ℃ and 250 ℃ fixed-point constant temperature performance.
5, other checks
To check the closure of the oven door to observe the sealing, and pay attention to the observation of whether the glass is clean and bright. Each function knob operation should be flexible. Also check whether the electric oven baking pan, baking net, baking fork and other spare parts are complete. Industrial oven is a general-purpose drying equipment, by the steel plate box, fiber filler composition, with hot air circulation system. Industrial oven for a variety of industrial materials drying, in the field of industrial production is widely used.
1, the structure of the industrial oven
Industrial oven for the internal and external double structure, the shell for the angle steel thin steel plate, inside and outside the double shell filled with fiber material. Industrial ovens use fiber material is mostly aluminum silicate, it can play a role in insulation, the formation of a reliable insulation layer. The industrial oven is equipped with hot air circulation system and temperature measurement and control system.
2, the principle of industrial oven
Industrial oven in the work of the operator through the instrument and the temperature sensor to obtain the temperature value of the inside of the industrial oven, through the control system for operation. The hot air circulation heating mode of the industrial oven, compared with the ordinary heat dissipation heating mode, has a better gas mobility, which can accelerate the drying speed of the materials in the industrial oven. The hot air circulation system of the industrial oven consists of air supply motor, wind wheel and electric heater, the air supply motor drives the wind wheel to send out the cold air, the cold air is heated by the electric heating equipment and carries the heat energy into the industrial oven through the air duct into the drying room of the industrial oven.
Industrial oven hot air circulation system is conducive to improving the uniformity of the air temperature, in the industrial oven door opening and closing the process of transporting materials, the temperature value will be affected by changes in the uniformity of the hot air circulation system is conducive to restoring the temperature value of the working state in the maximum speed. 1. Customized
Capacity to determine the size specifications to meet the production requirements, high capacity. You can choose the tracked industrial oven, that is, we say drying production line, tunnel oven, drying road.
2. Temperature
Choose a temperature 10 degrees higher than the actual use can be. According to the process requirements, calculate the actual required temperature difference to ensure the effect of baking. Example: If the use of temperature is 150 degrees, 220 degrees, 360 degrees, 440 degrees, according to the highest design temperature of 500 degrees do. 4 temperature, if the same product. Control of the best choice of silicon controlled. Different products, the use of low-temperature state, the temperature difference to be slightly larger. 150 degrees and 220 degrees of the actual use of the effect, not as good as low-temperature oven. The use of medium-temperature 500-degree oven, 150-degree baking temperature difference than the low-temperature 250-degree oven to be 2 to 5 degrees, but also depends on the quality of the manufacturer's equipment is good or bad.
3. Discharge
How to put the product in. You can give the oven layered, configure trays, there are mesh trays, solid trays, perforated trays. If you can use more racks, racks, but pay attention to a problem, that is, whether the operator is easy to operate. For example: a high 1500 wide 1500 depth 850mm oven, if you do baking tray to put items, we must consider whether the operator can hold the problem. Many factories operators are girls, height is more than 1500mm, if she has to lift that 1500 * 850 specifications of the baking tray, a little difficult Oh, not to mention the products to be baked multiple.
4. Placement site
If the oven is placed on the floor. To consider whether you can enter the door, into the elevator.
In fact, are some of the technical problems to be satisfied. The oven does not have much technical difficulty, the structure is simple, it is easy to be imitated. It is recommended to sign a technical agreement for performance acceptance is better. Problem 1, industrial oven temperature does not fall
Solution:
1, the industrial oven of the electric contactor contacts burned out bite, electric power can not be disconnected, the contactor should be replaced,
2, industrial oven temperature meter is damaged, should be replaced.
3, the industrial oven's temperature sensing wire is damaged, should be replaced.
Problem 2, industrial oven no wind or very little wind.
Solution:
1, check whether the industrial oven wind impeller is reversed, if reversed should be any two lines of the power cord to switch.
2, the industrial oven wind impeller fell down, you should open the oven door, remove the top wind impeller cover, the wind impeller re-installed, screws tighten, and then cover the cover.
3, the wind motor does not turn, check whether the power supply is out of phase, the lack of phase when immediately shut down to check the power cord, or motor burned out, the motor should be replaced
Problem three, the industrial oven temperature is not long
Solution:
1, the industrial oven heat pipe winding bad, should be folded off the oven right heat pipe cover, replace the heat pipe.
2, the industrial oven's heating pipe power line burned out or poor contact, should be rewired.
