What are the characteristics of vacuum furnace? Introduction of raw materials for vacuum furnace.

Vacuum furnace is a box-type drying equipment for drying dry materials under negative pressure. It uses a vacuum pump to extract air and moisture, so that a vacuum state is formed in the working room, the boiling point of water is reduced, and the drying speed is accelerated. Let's talk about the function of vacuum furnace in detail. What are the characteristics of vacuum furnace?

Raw materials of vacuum furnace

1, inner box material: the inner box is made of SUS stainless steel with high temperature and corrosion resistance in the world market, and the steel plate is 3mm thick, so that your goods can be processed in a clean working environment without being affected by unclean environment.

2. Raw materials for the outer box: The outer box is made of 1.5mm SCC steel plate which is widely used in the equipment industry in the world. The surface of the steel plate is treated with fine double-layer powder baking paint. Compared with the usual surface spraying treatment, the appearance is more beautiful and elegant, and the anti-corrosion and anti-rust functions are enhanced.

3. Thermal insulation material: Our thermal insulation material is imported Shiyan thermal insulation cotton, which has strong thermal insulation function and better thermal insulation function than ordinary thermal insulation cotton, and plays an excellent role in saving your electricity and reducing the impact on the ambient temperature of the equipment.

The PID microcomputer active temperature controller is selected. By setting the upper and lower limits of the internal temperature, it gives an alarm to the over-temperature problem in the machine studio, stops the power output, and ensures that the goods in the maintenance machine will not cause unnecessary losses due to over-temperature.

1. Overtemperature maintenance system: When the power input of the whole machine is too high, the machine is equipped with overtemperature maintenance system and active fuse blowing system.

2. High temperature maintenance system: When the temperature is out of control due to external force, this system will actively stop the power supply of the whole machine when it exceeds the set temperature 10 degrees, thus maintaining the safety of your goods and machines.

3. Over-current maintenance system: When the power of the whole machine exceeds the normal power due to excessive applied voltage or other reasons, the system will actively cut off the power supply to protect the industrial control components of the whole machine from being damaged.

Why is it necessary to vacuum the vacuum furnace before heating?

1. Put the commodity into a vacuum furnace and vacuum it to extract the extractable gas components from the commodity raw materials. If the goods are heated first, the gas will expand when heated. Due to the excellent sealing performance of the vacuum furnace, the infinite pressure generated by inflation may cause the toughened glass of the observation window to burst. This is a potential risk. The vacuum furnace operates according to the procedure of vacuumizing first and then heating up.

This can prevent this risk. 2. If the vacuum furnace is operated according to the procedure of heating first and then vacuumizing, when the heated air is pumped out by the vacuum pump, the heat will be brought to the vacuum pump, resulting in a high temperature rise of the vacuum pump and possibly reducing the power of the vacuum pump.

3. The heated gas is led to a vacuum pressure gauge,

The temperature of the vacuum pressure gauge will increase. If the temperature rise exceeds the application temperature range specified by the vacuum pressure gauge, the indication of the vacuum pressure gauge may be wrong. The accurate use of vacuum furnace should be vacuumizing first and then heating up. After the vacuum furnace reaches the extra temperature, if it is found that the vacuum degree decreases, it will be beneficial to prolong the service life of the vacuum furnace.
