High Temperature Trolley ovenPrecautions for use
High temperature trolley oven is a device that uses electric wire compartment to heat the object to dry. It is suitable for baking, drying, heat treatment, etc., 5~300℃ than room temperature height (some high 200 ℃), and the sensitivity is usually ±1℃. There are many types of oven in high temperature trolley, but the basic structure is similar, which is generally composed of three parts: box, Electric heating system and active temperature control system. Its use and precautions are summarized as follows:
1. The oven should be placed in the indoor drying and horizontal place to avoid oscillation and corrosion.
2. Pay attention to the safe use of electricity, according to the oven power consumption installation to meet the capacity of the power supply gate knife. Choose the satisfied power wire, and should have a good grounding line.
3. The oven with an electrical contact Mercury thermometer thermostat shall leave the two wires of the electrical contact thermometer to the two wiring columns at the top of the box. An ordinary mercury thermometer is also stabbed into the exhaust valve, (the thermometer in the exhaust valve is used to proofread the electrical contact Mercury thermometer and the actual temperature in the observation box) to open the hole in the exhaust valve. Adjust the electrical contact Mercury thermometer to the desired temperature and fasten the screws on the steel cap to reach the intention of constant temperature. However, it is important to note that when adjusting, do not spin the indicator iron outside the scale.
4. When all the preparation is ready, the specimen can be placed in the oven, and then connected and turned on the power supply, red indicator light indicates that the box has been heated. When the temperature reaches the controlled temperature, the red light extinguishes the green light, beginning the constant temperature. In order to avoid the failure of temperature control, you must also look after.
5. When putting in the test, you should pay attention to the placement can not be too dense. The heat sink should not be placed on the test products, so as not to affect the flow of hot air to the movement. Stop baking flammable, explosive, volatile and corrosive items.
6. When the requirements observe the condition of the sample in the work room, the outsider box door can be opened and observed through the glass door. But the box door to as little as possible to open as well, so as not to affect the constant temperature. Especially when working at more than 200 ℃, opening the door of the box may cause the glass door to plummet and break.
7. An oven with a blast must open the blower during heating and constant temperature, otherwise it will affect the uniformity of the studio temperature and damage the heating element.
8. When the work is finished, the power supply should be cut off in time to ensure safety.
9. Keep clean inside and outside the oven.
10. When used, the temperature should not exceed the Zui high use temperature of the oven.
11. In order to avoid burning bad, use special things when taking the test product.
