Temperature control system

1. Temperature control is PID touch screen instrument (TEMI580), single-point or program-type temperature control, which can be automatically calculated, PV/SV simultaneously displayed and touch setting;With the memory function (such as temperature and time), remember the temperature and time of each test process.
2. Function of timer: the meter is equipped with (hours and minutes can be set), and the temperature will be timed.
3. At the same time, the temperature of the upper, middle and lower center points in the cabinet is also displayed by the meter, without recording;
4. Temperature line (PT100);
5. Output is 3-32v;
6. The current controller is: SSR of solid relay has no contact;

7, rate of temperature: 100 ℃, about 15 minutes to temperature control instrument, need constant temperature 15 to 20 minutes, the internal temperature to reach;

8. Adopt three-side heating and thermal radiation convection, and the heating pipe is installed on the left, right and bottom of the outer wall of the inner box;
9. Heating element: stainless steel high-temperature heating tube;

10, temperature range: normal temperature + 30 to 250 ℃, the commonly used temperature is 90 degrees, 120 degrees, 180 degrees respectively;

11, the control precision of plus or minus 2.0 ℃;

12, display precision of 0.1 ℃;

13, the temperature in the cabinet deviation distribution uniformity + / – 5 ℃. (deviation) test chamber, the highest and the lowest layer

Vacuum system

1. The machine adopts a high-density silicone sealing strip for sealing at the door;
2. The vacuum degree is displayed by using SMC pressure gauge to display the instant vacuum degree and relative pressure.
3. Vacuum degree range of the machine: 0KPa to -100.0kpa, (vacuum degree: less than or equal to 265Pa);
4. Vacuum control mode: automatically control the vacuum to stop vacuuming and start automatically when the vacuum degree is lower than the lower limit. Work in this cycle.Manually decompress and fill with air or nitrogen;
5. The change of vacuum degree during the baking process of the product is only observed, and the data is not saved;
6. It is equipped with a 4-liter direct-connected vacuum pump with a power of 550W and a voltage of 220V.

Nitrogen charging device (manual air charging and decompressing)

1. Pressure regulating valve: control nitrogen pressure. Under normal use, nitrogen pressure should be adjusted to about 2kg.
2. Flow meter: control the size of nitrogen entering the box, with a range of 2L/ min-10lmin;
3. The nitrogen pipeline enters the front back of the box, and a 2-meter-long 10mm nitrogen hose is provided outside.
4. You need to provide nitrogen gas.

Protection system

1. Over-temperature protection system: when the temperature is out of control and the temperature is set beyond the over-temperature protection, the heating power supply will be automatically stopped to protect the safety of products and machines;
2. Circuit protection system: ground protection, phase loss protection and fast fuse.

Machine power supply:

1. Voltage 380V three-phase five-wire
2. Current 23A
3. Heating power of single box is 6KW
4. Total power: 15KW

Vacuum oven making principle:

1. After the power is connected, the power is normally energized;
2. Put the products to be baked;
3. Set the constant temperature time;
4. Set the temperature increase;
5. Start the vacuum, and stop the vacuum after the vacuum is reached;
6. Start heating;
7. Extract the product after baking.(for recycling)
