There are many types of drying ovens, but the basic structure is the same. The standard drying ovens are composed of three system structures: the cabinet, the electric heating system, and the temperature control system. When using the drying oven, their precautions are also the same, so everyone Don't speculate and misuse to misuse, you should roughly understand the introductory knowledge about the drying oven before going to the test operation.
1. Understand the little knowledge of the entrance of the drying oven and open the first door for you
The drying oven must be placed in a dry place to avoid vibration and corrosion. Many people ignore this problem because the conditions do not allow it. In the use of electricity, we should choose a sufficient power supply wire according to the sufficient capacity of the dry box power consumption power device, and should have a good grounding wire to ensure personal safety.
In terms of processing method, the oven with electric contact mercury thermometer thermostat should distinguish the two wires of the electric contact thermometer to the two terminals on the top of the box. In addition, an ordinary mercury thermometer is pulled out of the exhaust valve (the thermometer in the exhaust valve is used to correct the electrical contact mercury thermometer and to check the actual temperature in the box) to open the hole of the exhaust valve. After adjusting the electrical contact mercury thermometer to the desired temperature, tighten the screw on the steel cap to reach the goal of constant temperature. But we must pay attention not to turn the indicating iron out of the scale during conditioning. When using, we should also pay attention to the temperature not exceeding the maximum operating temperature of the drying oven. Every little bit of knowledge makes it easier for you to start!
2. Analyze the actual operation in and after the drying oven, giving you the data at a glance
When preparing the drying oven, put the test oven in the oven first, and then turn on the power. The red indicator light is on to indicate that the oven is heated. When the temperature reaches the controlled temperature, the red light goes out and the green light goes on, and the constant temperature starts. In order to avoid the failure of temperature control, it needs to be looked after. When placing the test sample, the sample distance should not be too close, and the sample should not be placed on the radiator plate, so as not to affect the downward flow of hot gas. It is forbidden to put flammable, explosive, volatile and corrosive items in the drying oven. Special note: in the drying oven with blast, the blower must be turned on during the process of heating and constant temperature, otherwise it will affect the temperature evenness and damage the heating element.
The power supply should be turned off in time after the test to ensure safety. When taking the test samples, please use the special tool for taking samples in order to avoid burns. After the test, the surface of the drying cabinet must be kept clean.
It should also be noted that drying ovens are widely used in various industries; such as electronic component drying, industrial and agricultural, medical and health, plastic machinery, production workshops or laboratories of universities and scientific research departments, etc. Baking and sterilization.
