Oven heating use note
The oven is heated by the electric heating wire layer object drying equipment. It is suitable for baking, drying, heat treatment and so on, which is higher than room temperature 8~300 C (some 200 degrees Celsius), and the sensitivity is usually about 1. The model of the oven is a lot, but the basic structure is similar, which is composed of three parts, the box body, the electric heating system and the automatic temperature control system. Its use and precautions are summarized as follows:
1 oven should be placed in the room to dry and level, to prevent vibration and corrosion.
2 to Caution! Electricity, according to the power switch power installed capacity enough oven. Selection of adequate power supply, and should have a good grounding.
3 electric contact mercury thermometer type temperature controller of the oven should be the electric contact thermometer two wires were connected to the top of the box on the top of the two terminal. Another common mercury thermometer into the exhaust valve, (the valve in the thermometer is used to check the electric contact mercury thermometer and the actual temperature in the box to open the vent valve. Adjust the electric contact mercury thermometer to the required temperature to tighten the screw on the steel cap, in order to achieve the purpose of constant temperature. But must pay attention to the adjustment must not be directed to the scale of the iron scale.
4 when all ready to work in the oven can be put into the oven, and then connect and turn on the power, the red indicator light indicates that the box has been heated. When the temperature reaches the temperature control, the red light goes out the green light, and begins to constant temperature. In order to prevent the failure of temperature control, but also to take care of.
5 should pay attention to the arrangement should not be too dense. Heat radiating plate should not be put on the test article, so as not to affect the flow of hot gas flow. Flammable, explosive, volatile and corrosive substances are prohibited.
6 when the need to observe the situation in the studio sample, can be opened outside the box door, through the glass door observation. But the box door to as little as possible to open as well, so as not to affect the constant temperature. Especially when working in 200 degrees above, open door may make the glass door sudden rupture.
7 there is a blast oven, in the process of heating and constant temperature must be turned on the blower, otherwise affect the uniformity of the temperature of the studio and damage the heating element.
8 after the completion of the work should be promptly cut off the power supply, to ensure safety.
9 keep clean inside and outside the oven.
10 when used, the temperature should not exceed the maximum operating temperature of the oven.
11 in order to prevent burns, take the test product to use special tools.
