Structure and use of hot air circulation oven and attention
First, an overview
Hot air circulation oven is mainly used in industry and trade of agricultural production, scientific research, medical and health, the laboratory to test products for the baking, heating, heat treatment. Note: hot air circulation oven does not apply to volatile, flammable items. The temperature of the drying box of the hot air circulation oven can be arbitrarily adjusted from 10 to 300 C, and the temperature of the selected working temperature can be adjusted automatically. The digital display Shu type temperature controller, sensitive and reliable, convenient operation, more intuitive and clear digital display. Is a college, medical and health, environmental protection and other research departments of laboratory and industrial, mining, agricultural production line test or production line. Hot air circulation oven blast device, wind through the air duct into the studio, prompted the studio heated air circulation convection, which has good temperature uniformity.
Two, hot air circulation oven structure:
1, hot air circulation oven box body is formed by a thin steel plate and steel, the shell and the studio to glass fiber insulation materials, inside the storm door with glass door to peep at the studio.
2, all electrical wiring installed in the box on the right side of the control room, temperature controller and the switch control part were outside the control room, control room door detachable, easy to repair.
Three, hot air circulation oven use and attention:
1, hot air circulation oven should be placed in the room for the use of the level of drying, the cabinet must be effective.
2, in the power supply line, the user should be installed with the drying box current corresponding to the off switch for this box.
3, each unit of the drying box studio accompanied by two pieces of network type shelf for placing test, and according to the sample size adjustment shelf spacing, placement test material shoulds not be too close, hot air circulation, the studio floor above no placement test, avoid due to overheating burn test.
4, hot air circulation oven for digital display temperature controller, select set incessantly temperature, the dashboard temperature test digital set according to meet the required number of temperature can start work.
5, temperature control instrument indicator: green for electric heater in work, red light for the heating is stopped, when heated to a box temperature reaches the set temperature after the green light to red light, then temperature controller will continue to flip, alternating traffic lights flash, namely for constant temperature state, but because just when the temperature is constant, studio internal heat is not uniform, even when the temperature reaches the setting box has been in constant temperature state, there may there will be heat continues to heat up, this phenomenon in half an hour after gradually disappear tends to be stable.
6, when the phone is switched on, in order to seek to accelerate the heating time, heating switch to a high temperature, two groups of heaters and heating to temperature, the heating switch to low temperature, leaving only a group of heater power consumption is saved.
7, fetching test objects, do not hit the sensor into the studio, with the temperature sensor to head loss prevention and control failure.
8, before starting to unscrew the box top exhaust valve is about 10mm, in order to transform the air convection, and the moisture and exhaust gas.
9, you want to observe the studio in the testing material, open the door, or peeping inward from the glass door, but doors don't often open is appropriate, to avoid heat leakage and when the temperature rises to about 300 degrees, open box doors may be made of glass rapid cooling and rupture.
10, this series of dry box for non - explosive products, do not bake baked flammable, explosive, volatile substances, in case of explosion.
11, the use is completed, must be cut off the power supply.
