9. Vacuum pump installation method: the vacuum pump is installed in the lower part of the machine;

10. The inner box material is: high temperature resistant SUS304# stainless steel industrial board, the thickness of the steel plate is 5.0mm, and the treatment is vacuumed without deformation;

11. The outer box is made of: 1.2mm thick cold-rolled steel plate, and the outer surface of the steel plate is treated with double-sided paint (white);

12, insulation material: fiber rock wool, good insulation performance, thickness 100mm;

13. Equipment use environment: working environment temperature is 5 to 25 °C, working environment humidity is 35% to 75%;

14. The movable caster and adjustable fixed foot cup are installed at the bottom of the machine.

Temperature control

system

1. The temperature controller is a digital display instrument (Taiwan Taisong instrument), single-point temperature control, automatic calculation, PV/SV simultaneous display, button setting;

2, timing function: 0-9999 hours / min / sec, warm to the timing, time to stop heating, and alarm prompts;

3. The temperature sensing line is (K) type;

4, the output is 3-32V;

5. The current controller is: SSR solid state relay;

6. Heating method: heat radiation with three sides heating; (left, right, and bottom sides of the inner box wall)

7. The heating element is: stainless steel high temperature resistant heating tube;

8, temperature range: normal temperature +15 ~ 100 °C adjustable;

9, instrument control accuracy: ± 0.5 ° C;

10. Instrument accuracy display: 0.1 °C;

11, the temperature deviation inside the box: ± 6 ° C. (no vacuum test).

1. This machine adopts high-density silicone sealing strip to seal at the door, and the sealing performance of the whole machine is good;

2. Use Panasonic digital display vacuum gauge to display the vacuum inside the box;

Negative pressure display pressure gauge

3. The vacuum sensor is: automatic air pressure sensing;

4. Vacuum range: 0.0KPa to -100.0KPa;

5, vacuum pressure leakage rate: about 1.0KPa per hour;

6. The vacuum control mode is: automatic control, reaching the upper limit set value stop, lower than the lower limit start, and thus circulating to maintain the optimal low pressure state;

7. Pressure display mode: For relative display, if the test vacuum is 70.0KPa, the standard air pressure is 101.3KPa-70.0KPa=31.3KPa, and the vacuum gauge is set to -31.3KPa. The set data is pumped away. Pressure, other parameters are calculated in the same way;

8. Vacuum pump configuration: one XD-20 vacuum pump, voltage 220V, power 0.9KW;

9, vacuum pump exhaust device, need to be exhausted to the outside (your company to handle it).

1. Over-temperature protection system: independent over-temperature protection device, when the over-temperature protection set temperature is exceeded, the heating supply is automatically stopped, thus protecting the safety of products and machines;

2, circuit protection system: phase sequence protection, ground protection, overload protection, circuit breakers, etc..

machine

power supply
