Electric blast drying oven operating procedures
(1) Dry box is used for baking, drying or other heating of the sample. The maximum operating temperature is 300 °C. The drying oven works under the conditions that the ambient temperature is not more than 40 ° C and the relative humidity of the air is not more than 85%.
(2) Use a special plug and socket and ground it with a wire that is twice as thick as the power cord. Check the electrical insulation performance before use, and pay attention to whether there is open circuit, short circuit and leakage.
(3) Put the thermometer on the box, turn on the power supply and adjust the temperature control knob to the set temperature. When the AC contact switch is just disconnected, check whether the reading of the thermometer matches the set value. If there is any difference, fine-tune it until the constant temperature is met. Set the temperature.
(4) Open the top or bottom vent to remove moisture from the box.
(5) The maximum average load of the test steel plate is 15Kg, and the placement should not be too heavy or too dense. Be sure to leave a gap. The test piece should not be placed on the bottom plate of the studio.
(6) It is strictly forbidden to put flammable and volatile substances in the drying box to prevent explosion.
(7) Connect the power supply, the green indicator light is on, the blower switch is turned on, the blower motor is running, the heating power is turned on, and the drying box is put into working state.
(8) When working, the door should not be opened frequently to avoid affecting the constant temperature field.
(9) There is no over-temperature protection device for this equipment. Therefore, there should be a special person to monitor the temperature inside the box when working. If the temperature is out of control, it should be checked off in time to avoid accidents.
